Geothermal Well Maintenance and Repair in Cerro Prieto  

DOE Green Energy (OSTI)

When the first well is drilled at a geothermal field, procedures for the cleaning, repair, and control of wells should be established. This aspect will be increasingly important as more wells are drilled. Equipment, tools and techniques need to be improved to achieve economic and safe results. Different systems have been developed and applied in maintenance of wells, in problems of casing incrustations, repairs, plugging, and well control. These systems should be improved, even though they have been reasonably satisfactory to date.

Review of Maintenance and Repair Times for Components in Technological Facilities  

SciTech Connect

This report is a compilation of some unique component repair time data and it also presents citations of more extensive reports where lists of repair times can be found. This collection of information should support analysts who seek to quantify maintainability and availability of high technology and nuclear energy production systems. While there are newer sources of repair time information, most, if not all, of the newer sources are proprietary and cannot be shared. This report offers data that, while older, is openly accessible and can serve as reasonable estimates of repair times, at least for initial studies. Some times were found for maintenance times in radiation environments, and some guidance for multiplicative factors to use to account for work in contamination areas.

Development and validation of bonded composite doubler repairs for commercial aircraft.  

Science Conference Proceedings (OSTI)

A typical aircraft can experience over 2,000 fatigue cycles (cabin pressurizations) and even greater flight hours in a single year. An unavoidable by-product of aircraft use is that crack, impact, and corrosion flaws develop throughout the aircraft's skin and substructure elements. Economic barriers to the purchase of new aircraft have placed even greater demands on efficient and safe repair methods. The use of bonded composite doublers offers the airframe manufacturers and aircraft maintenance facilities a cost effective method to safely extend the lives of their aircraft. Instead of riveting multiple steel or aluminum plates to facilitate an aircraft repair, it is now possible to bond a single Boron-Epoxy composite doubler to the damaged structure. The FAA's Airworthiness Assurance Center at Sandia National Labs (AANC), Boeing, and Federal Express completed a pilot program to validate and introduce composite doubler repair technology to the U.S. commercial aircraft industry. This project focused on repair of DC-10 fuselage structure and its primary goal was to demonstrate routine use of this repair technology using niche applications that streamline the design-to-installation process. As composite doubler repairs gradually appear in the commercial aircraft arena, successful flight operation data is being accumulated. These commercial aircraft repairs are not only demonstrating the engineering and economic advantages of composite doubler technology but they are also establishing the ability of commercial maintenance depots to safely adopt this repair technique. This report presents the array of engineering activities that were completed in order to make this technology available for widespread commercial aircraft use. Focused laboratory testing was conducted to compliment the field data and to address specific issues regarding damage tolerance and flaw growth in composite doubler repairs. Fatigue and strength tests were performed on a simulated wing repair using a substandard design and a flawed installation. In addition, the new Sol-Gel surface preparation technique was evaluated. Fatigue coupon tests produced Sol-Gel results that could be compared with a large performance database from conventional, riveted repairs. It was demonstrated that not only can composite doublers perform well in severe off-design conditions (low doubler stiffness and presence of defects in doubler installation) but that the Sol-Gel surface preparation technique is easier and quicker to carry out while still producing optimum bonding properties. Nondestructive inspection (NDI) methods were developed so that the potential for disbond and delamination growth could be monitored and crack growth mitigation could be quantified. The NDI methods were validated using full-scale test articles and the FedEx aircraft installations. It was demonstrated that specialized NDI techniques can detect flaws in composite doubler installations before they reach critical size. Probability of Detection studies were integrated into the FedEx training in order to quantify the ability of aircraft maintenance depots to properly monitor these repairs. In addition, Boeing Structural Repair and Nondestructive Testing Manuals were modified to include composite doubler repair and inspection procedures. This report presents the results from the FedEx Pilot Program that involved installation and surveillance of numerous repairs on operating aircraft. Results from critical NDI evaluations are reported in light of damage tolerance assessments for bonded composite doublers. This work has produced significant interest from airlines and aircraft manufacturers. The successful Pilot Program produced flight performance history to establish the durability of bonded composite patches as a permanent repair on commercial aircraft structures. This report discusses both the laboratory data and Pilot Program results from repair installations on operating aircraft to introduce composite doubler repairs into mainstream commercial aircraft use.

Open source software development and maintenance: an exploratory analysis  

E-Print Network (OSTI)

The purpose of this research was to create measures and models for the evaluation of Open Source Software (OSS) projects. An exploratory analysis of the development and maintenance processes in OSS was conducted for this purpose. Data mining and text mining techniques were used to discover knowledge from transactional datasets maintained on OSS projects. Large and comprehensive datasets were used to formulate, test and validate the models. A new multidimensional measure of OSS project performance, called project viability was defined and validated. A theoretical and empirical measurement framework was used to evaluate the new measure. OSS project data from SourceForge.net was used to validate the new measure. Results indicated that project viability is a measure of the performance of OSS projects. Three models were then created for each dimension of project viability. Multiple data mining techniques were used to create the models. Variables identified from process, product, resource and end-user characteristics of the project were used. The use of new variables created through text mining improved the performance of the models. The first model was created for OSS projects in the development phase. The results indicated that end-user involvement could play a significant role in the development of OSS projects. It was also discovered that certain types of projects are more suitable for development in OSS communities. The second model was developed for OSS projects in their maintenance phase. A two-stage model for maintenance performance was selected. The results indicated that high project usage and usefulness could improve the maintenance performance of OSS projects. The third model was developed to investigate the affects of maintenance activities on the project internal structure. Maintenance data for Linux project was used to develop a new taxonomy for OSS maintenance patches. These results were then used to study the affects of various types of patches on the internal structure of the software. It was found that performing proactive maintenance on the software moderates its internal structure.

Development of a composite repair system for reinforcing offshore risers  

E-Print Network (OSTI)

A research program was conducted to investigate the application of composite materials in repairing corroded offshore risers, leading to the development of an optimized repair using a hybrid carbon/E-glass system. The objective of this research program was to investigate the feasibility of extending onshore composite repair techniques to offshore risers by developing integrated analytical and experimental methods. The study considered loads typical for offshore risers including internal pressure, tension, and bending. To fulfill this objective efforts included a state of the art assessment of current composite repair technology, designing a carbon-based composite repair system optimized by numerical simulation with prototype testing, and providing guidelines for industry in repairing and reinforcing offshore risers using composite materials. Research efforts integrated numerical modeling, as well as full-scale testing that included four composite repair manufacturers to assess the current state of the art on pipe samples with simulated corrosion reinforced with composite materials. Analysis and testing were also performed on the optimized carbon/E-glass system. The results of this program demonstrated that composite materials are a viable means for repairing corroded offshore steel risers as adequate reinforcement ensures that the steel risers are not loaded beyond acceptable design limits. For corroded risers, the results demonstrated through analysis and full-scale testing efforts that properly designed composite repair systems can provide adequate structural reinforcement to ensure that excessive strains are not induced in the steel when subjected to internal pressure, axial tension, and bending design loads. This was verified experimentally using strain gages placed beneath the composite repair. This program is the first of its kind and is thought to contribute significantly to the future of offshore riser repairs. It is likely that the findings of this program will foster future investigations involving operators by integrating their insights regarding the need for composite repair based on emerging technology. One of the most significant contributions to the existing body of work is the use of limit analysis in developing design limits for the repair of steel pipes using composite materials.

Comparing Maintenance Costs of Geothermal Heat Pump Systems with other HVAC Systems in Lincoln Public Schools: Repair, Service, and Corrective Actions  

DOE Green Energy (OSTI)

The Lincoln Public School District, in Lincoln, Nebraska, recently installed vertical-bore geothermal heat pump systems in four, new, elementary schools. Because the district has consistent maintenance records and procedures, it was possible to study repair, service and corrective maintenance requests for 20 schools in the district. Each school studied provides cooling to over 70% of its total floor area and uses one of the following heating and cooling systems: vertical-bore geothermal heat pumps (GHPs), air-cooled chiller with gas-fired hot water boiler (ACUGHWB), water-cooled chiller with gas-fired hot water boiler (WCCYGHWB), or water-cooled chiller with gas-fired steam boiler (WCUGSB). Preventative maintenance and capital renewal activities were not included in the available database. GHP schools reported average total costs at 2.13 cents/ft{sup 2}-yr, followed by ACC/GHWB schools at 2.88 cents/ft{sup 2}-yr, WCC/GSB schools at 3.73 cents/ft{sup 2}-yr, and WCC/GHWB schools at 6.07 cents/ft{sup 2}-yr. Because of tax-exemptions on material purchases, a reliance on in-house labor, and the absence of preventative maintenance records in the database, these costs are lower than those reported in previous studies. A strong relationship (R{sup 2}=O.52) was found between costs examined and cooling system age: the newer the cooling equipment, the less it costs to maintain.

Developing a Novel Framework for Quality System and Systems Thinking to Integrate: A Paradigm Shift in Maintenance  

E-Print Network (OSTI)

Abstract—This paper presents a need of paradigm shift in maintenance system so as to improve performance of overall system in this global competition. It discovers flaws in present day maintenance strategies that were considered to be the rationale behind the need for this new paradigm; changing scheme from a problem solving maintenance to a problem understanding maintenance. To reply to that research gap, this study unveils want in quality system and systems thinking that must have got to be integrated into conception of the existing maintenance strategies. Having had demand for integration of these methodologies, this paper offers a novel framework that enable maintenance operatives to plan maintenance actions through the identification of true root cause of failures and the quest of optimal solutions by viewing problem as a system in its entirety. Unlike current maintenance strategies, the proposed framework will count not only ‘hard ’ factors but also their relationships with nascent ‘soft ’ factors as contributing elements in the cause of failure. It can then be developed from beneficial effect of integration between the Six Sigma and the System Dynamics benefiting from favorable merged characteristics of the two; quality system and systems thinking respectively, along with feedback mechanism. Details construction of the framework is explained thoroughly in every section of this paper. Keywords—cybernetics system engineering, maintenance system, manufacturing management, quality system, systems thinking, system dynamics, six sigma. I.

Development and validation of nondestructive inspection techniques for composite doubler repairs on commercial aircraft  

SciTech Connect

Composite doublers, or repair patches, provide an innovative repair technique which can enhance the way aircraft are maintained. Instead of riveting multiple steel or aluminum plates to facilitate an aircraft repair, it is possible to bond a single boron-epoxy composite doubler to the damaged structure. In order for the use of composite doublers to achieve widespread use in the civil aviation industry, it is imperative that methods be developed which can quickly and reliably assess the integrity of the doubler. In this study, a specific composite application was chosen on an L-1011 aircraft in order to focus the tasks on application and operation issues. Primary among inspection requirements for these doublers is the identification of disbonds, between the composite laminate and aluminum parent material, and delaminations in the composite laminate. Surveillance of cracks or corrosion in the parent aluminum material beneath the doubler is also a concern. No single nondestructive inspection (NDI) method can inspect for every flaw type, therefore it is important to be aware of available NDI techniques and to properly address their capabilities and limitations. A series of NDI tests were conducted on laboratory test structures and on full-scale aircraft fuselage sections. Specific challenges, unique to bonded composite doubler applications, were highlighted. An array of conventional and advanced NDI techniques were evaluated. Flaw detection sensitivity studies were conducted on applicable eddy current, ultrasonic, X-ray and thermography based devices. The application of these NDI techniques to composite doublers and the results from test specimens, which were loaded to provide a changing flaw profile, are presented in this report. It was found that a team of these techniques can identify flaws in composite doubler installations well before they reach critical size.

Reactive Maintenance | Department of Energy  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Reactive Maintenance Reactive Maintenance Reactive Maintenance October 7, 2013 - 9:40am Addthis Reactive maintenance follows a run-it-until-it-breaks strategy where no actions or efforts are taken to maintain equipment as intended by the manufacturer. Studies indicate this is still the predominant mode of maintenance for Federal facilities. Advantages Reactive maintenance advantages are a double-edged sword. Federal agencies following a purely reactive maintenance strategy can expect little expenditures for manpower or system upkeep until something breaks. However, systems do break. With new equipment, Federal agencies can expect minimal incidents of failure. However, older equipment often experiences higher failure incidents and costlier repairs. Other advantages of reactive maintenance are:

The good computerized maintenance management systems available today provide Plant Engineers with sufficient data to institute policies and procedures to materially affect the company profits. Regrettably, the vast majority of these Engineers and their Maintenance Managers seem content to simply produce PM work orders, maintenance equipment repair histories and generate a few activity reports. A straightforward and practical application of the available cost and performance data enables maintenance management to constantly fine tune operational procedures to minimize cost and equipment failure from the available data. Using this data, the manager can easily measure the total effect of maintenance on his company's overall performance. The practical application of this data to reduce overall maintenance cost and to increase equipment availability is discussed in this paper.

Substation Reliability Centered Maintenance  

SciTech Connect

Substation Reliability Centered Maintenance (RCM) is a technique that is used to develop maintenance plans and criteria so the operational capability of substation equipment is achieved, restored, or maintained. The objective of the RCM process is to focus attention on system equipment in a manner that leads to the formulation of an optimal maintenance plan. The RCM concept originated in the airline industry in the 1970s and has been used since 1985 to establish maintenance requirements for nuclear power plants. The RCM process is initially applied during the design and development phase of equipment or systems on the premise that reliability is a design characteristic. It is then reapplied, as necessary, during the operational phase to sustain a more optimal maintenance program based on actual field experiences. The purpose of the RCM process is to develop a maintenance program that provides desired or specified levels of operational safety and reliability at the lowest possible overall cost. The objectives are to predict or detect and correct incipient failures before they occur or before they develop into major defects, reduce the probability of failure, detect hidden problems, and improve the cost-effectiveness of the maintenance program. RCM accomplishes two basic purposes: (1) It identifies in real-time incipient equipment problems, averting potentially expensive catastrophic failures by communicating potential problems to appropriate system operators and maintenance personnel. (2) It provides decision support by recommending, identifying, and scheduling preventive maintenance. Recommendations are based on maintenance criteria, maintenance history, experience with similar equipment, real-time field data, and resource constraints. Hardware and software are used to accomplish these two purposes. The RCM system includes instrumentation that monitors critical substation equipment as well as computer software that helps analyze equipment data.

www.mdpi.com/journal/ijms Chromatin Dynamics during Nucleotide Excision Repair: Histones on the Move  

E-Print Network (OSTI)

Abstract: It has been a long-standing question how DNA damage repair proceeds in a nuclear environment where DNA is packaged into chromatin. Several decades of analysis combining in vitro and in vivo studies in various model organisms ranging from yeast to human have markedly increased our understanding of the mechanisms underlying chromatin disorganization upon damage detection and re-assembly after repair. Here, we review the methods that have been developed over the years to delineate chromatin alterations in response to DNA damage by focusing on the well-characterized Nucleotide Excision Repair (NER) pathway. We also highlight how these methods have provided key mechanistic insight into histone dynamics coupled to repair in mammals, raising new issues about the maintenance of chromatin integrity. In particular, we discuss how NER factors and central players in chromatin dynamics such as histone modifiers, nucleosome remodeling factors, and histone chaperones function to mobilize histones during repair.

Federal Energy Management Program: Maintenance Types  

NLE Websites -- All DOE Office Websites (Extended Search)

Maintenance Types Maintenance Types Proper operations and maintenance (O&M) goes beyond repairing equipment after it breaks. Several maintenance strategies exist to prevent systems disrepair and degradation. A combination of the following can ensure an optimal blend of cost and life-cycle effectiveness: Reactive Maintenance: Follows a "run it until it breaks" strategy. No action or effort is taken to maintain equipment, prevent failure, or ensure life of the system - even if actions are suggested by the manufacturer. Preventive Maintenance: Refers to a series of actions performed on calendar time or machine run time schedules. Predictive Maintenance: Strives to detect the onset of equipment degradation and address the problems as they are identified. Several predictive maintenance technologies exist.

INTERNAL REPAIR OF PIPELINES  

Science Conference Proceedings (OSTI)

The two broad categories of fiber-reinforced composite liner repair and deposited weld metal repair technologies were reviewed and evaluated for potential application for internal repair of gas transmission pipelines. Both are used to some extent for other applications and could be further developed for internal, local, structural repair of gas transmission pipelines. Principal conclusions from a survey of natural gas transmission industry pipeline operators can be summarized in terms of the following performance requirements for internal repair: (1) Use of internal repair is most attractive for river crossings, under other bodies of water, in difficult soil conditions, under highways, under congested intersections, and under railway crossings. (2) Internal pipe repair offers a strong potential advantage to the high cost of horizontal direct drilling when a new bore must be created to solve a leak or other problem. (3) Typical travel distances can be divided into three distinct groups: up to 305 m (1,000 ft.); between 305 m and 610 m (1,000 ft. and 2,000 ft.); and beyond 914 m (3,000 ft.). All three groups require pig-based systems. A despooled umbilical system would suffice for the first two groups which represents 81% of survey respondents. The third group would require an onboard self-contained power unit for propulsion and welding/liner repair energy needs. (4) The most common size range for 80% to 90% of operators surveyed is 508 mm (20 in.) to 762 mm (30 in.), with 95% using 558.8 mm (22 in.) pipe. Evaluation trials were conducted on pipe sections with simulated corrosion damage repaired with glass fiber-reinforced composite liners, carbon fiber-reinforced composite liners, and weld deposition. Additional un-repaired pipe sections were evaluated in the virgin condition and with simulated damage. Hydrostatic failure pressures for pipe sections repaired with glass fiber-reinforced composite liner were only marginally greater than that of pipe sections without liners, indicating that this type of liner is only marginally effective at restoring the pressure containing capabilities of pipelines. Failure pressures for larger diameter pipe repaired with a semi-circular patch of carbon fiber-reinforced composite lines were also marginally greater than that of a pipe section with un-repaired simulated damage without a liner. These results indicate that fiber reinforced composite liners have the potential to increase the burst pressure of pipe sections with external damage Carbon fiber based liners are viewed as more promising than glass fiber based liners because of the potential for more closely matching the mechanical properties of steel. Pipe repaired with weld deposition failed at pressures lower than that of un-repaired pipe in both the virgin and damaged conditions, indicating that this repair technology is less effective at restoring the pressure containing capability of pipe than a carbon fiber-reinforced liner repair. Physical testing indicates that carbon fiber-reinforced liner repair is the most promising technology evaluated to-date. In lieu of a field installation on an abandoned pipeline, a preliminary nondestructive testing protocol is being developed to determine the success or failure of the fiber-reinforced liner pipeline repairs. Optimization and validation activities for carbon-fiber repair methods are ongoing.

Kalispell Maintenance Headquarters Project : Environmental Assessment.  

Science Conference Proceedings (OSTI)

The facilities needed to maintain and repair Bonneville Power Administration (BPA's) electrical equipment in northwest Montana are currently in two locations: A maintenance headquarters at the Kalispell Substation, and a temporary leased facility south of Kalispell. The present situation is not efficient. There is not enough space to accommodate the equipment needed at each site, and coordination and communication between the two sites is difficult. Also, two sites means duplication of equipment and facilities. BPA needs a single, centralized facility that would efficiently accommodate all the area's maintenance activities and equipment. BPA proposes to build a maintenance headquarters facility consisting of 2 to 4 single-story buildings totaling about 35,000 square feet (office spaces and workshop areas); an open-ended vehicle storage building (carport style); a fenced-in storage year; a storage building for flammables, herbicides, and hazardous wastes; and a parking lot. The facility would require developing about 6 to 10 acres of land. Two sites are being considered for the proposed project (see the attached map for locations). This report is the environmental assessment of the two options.

ARCHY (Analysis and Reverse Engineering of Code Using Hierarchy and Yourdon): A tool for Fortran code maintenance and development  

SciTech Connect

Analysis and Reverse Engineering of Code Using Hierarchy and Yourdon (ARCHY) diagrams is a tool for development and maintenance of FORTRAN programs. When FORTRAN source code is read by ARCHY, it automatically creates a database that includes a data dictionary, which lists each variable, its dimensions, type, category (set, referenced, passed), module calling structure, and common block information. The database exists in an ASCII file that can be directly edited or maintained with the ARCHY database editor. The database is used by ARCHY to product structure charts and Yourdon data flow diagrams in PostScript format. ARCHY also transfers database information such as a variable definitions, module descriptions, and technical references to and from module headers. ARCHY contains several utilities for making programs more readable. It can automatically indent the body of loops and conditionals and resequence statement labels. Various language extensions are translated into FORTRAN-77 to increase code portability. ARCHY frames comment statements and groups FORMAT statements at the end of modules. It can alphabetize modules within a program, end-of-line labels can be added, and it can also change executable statements to upper or lower case. ARCHY runs under the VAX-VMS operating system and inputs from VAX-FORTRAN, IBM-FORTRAN, and CRAY FORTRAN sources files.

Science Conference Proceedings (OSTI)

Neutron detectors are commonly used by the nuclear materials processing industry to monitor fissile materials in process vessels and tanks. The proper functioning of these neutron monitors must be periodically evaluated. We have developed and placed in routine use a PC-based multichannel analyzer (MCA) system for on-line BF3 and He-3 gas-filled detector function testing. The automated system: 1) acquires spectral data from the monitor system, 2) analyzes the spectrum to determine the detector`s functionality, 3) makes suggestions for maintenance or repair, as required, and 4) saves the spectrum and results to disk for review. The operator interface has been designed to be user-friendly and to minimize the training requirements of the user. The system may also be easily customized for various applications

These headquarters buildings, however, were built in 1941 and have deteriorated to the point of needing extensive repair. They also lack sufficient inside storage space. New buildings cannot be constructed on the site because of surrounding development. In addition, the site is within an area exposed to industrial fallout (coal tar pitch and metallic particles) that may be damaging buildings, equipment, and vehicles. BPA is concerned about the potential health risk to headquarters staff from the fallout. In light of these problems, BPA proposes to construct a new operations and maintenance headquarters at a different location, and to demolish the existing headquarters. This paper discusses the environmental impacts of the proposed action and alternatives.

Terminal automation system maintenance  

SciTech Connect

Nothing has improved petroleum product loading in recent years more than terminal automation systems. The presence of terminal automation systems (TAS) at loading racks has increased operational efficiency and safety and enhanced their accounting and management capabilities. However, like all finite systems, they occasionally malfunction or fail. Proper servicing and maintenance can minimize this. And in the unlikely event a TAS breakdown does occur, prompt and effective troubleshooting can reduce its impact on terminal productivity. To accommodate around-the-clock loading at racks, increasingly unattended by terminal personnel, TAS maintenance, servicing and troubleshooting has become increasingly demanding. It has also become increasingly important. After 15 years of trial and error at petroleum and petrochemical storage and transfer terminals, a number of successful troubleshooting programs have been developed. These include 24-hour {open_quotes}help hotlines,{close_quotes} internal (terminal company) and external (supplier) support staff, and {open_quotes}layered{close_quotes} support. These programs are described.

Decontamination and decommissioning surveillance and maintenance report for FY 1991  

SciTech Connect

The Decontamination and Decommissioning (D D) Program has three distinct phases: (1) surveillance and maintenance (S M); (2) decontamination and removal of hazardous materials and equipment (which DOE Headquarters in Washington, D.C., calls Phase I of remediation); and (3) decommissioning and ultimate disposal, regulatory compliance monitoring, and property transfer (which DOE Headquarters calls Phase II of remediation). A large part of D D is devoted to S M at each of the sites. Our S M activities, which are performed on facilities awaiting decommissioning, are designed to minimize potential hazards to human health and the environment by: ensuring adequate containment of residual radioactive and hazardous materials; and, providing physical safety and security controls to minimize potential hazards to on-site personnel and the general public. Typically, we classify maintenance activities as either routine or special (major repairs). Routine maintenance includes such activities as painting, cleaning, vegetation control, minor structural repairs, filter changes, and building system(s) checks. Special maintenance includes Occupational Safety and Health Act facility upgrades, roof repairs, and equipment overhaul. Surveillance activities include inspections, radiological measurements, reporting, records maintenance, and security (as required) for controlling and monitoring access to facilities. This report summarizes out FY 1991 S M activities for the Tennessee plant sites, which include the K-25 Site, the Gas Centrifuge facilities, ORNL, and the Y-12 Plant.

Developing a CD-CBM Anticipatory Approach for Cavitation - Defining a Model-Based Descriptor Consistent Across Processes, Phase 1 Final Report Context-Dependent Prognostics and Health Assessment: A New Paradigm for Condition-based Maintenance SBIR Topic No. N98-114  

SciTech Connect

The objective of this research, and subsequent testing, was to identify specific features of cavitation that could be used as a model-based descriptor in a context-dependent condition-based maintenance (CD-CBM) anticipatory prognostic and health assessment model. This descriptor is based on the physics of the phenomena, capturing the salient features of the process dynamics. The test methodology and approach were developed to make the cavitation features the dominant effect in the process and collected signatures. This would allow the accurate characterization of the salient cavitation features at different operational states. By developing such an abstraction, these attributes can be used as a general diagnostic for a system or any of its components. In this study, the particular focus will be pumps. As many as 90% of pump failures are catastrophic. They seem to be operating normally and fail abruptly without warning. This is true whether the failure is sudden hardware damage requiring repair, such as a gasket failure, or a transition into an undesired operating mode, such as cavitation. This means that conventional diagnostic methods fail to predict 90% of incipient failures and that in addressing this problem, model-based methods can add value where it is actually needed.

The SMAP provides an annual status of maintenance initiatives completed and planned, a summary of performance indicators, a summary of maintenance backlog, a listing of real property and capital equipment maintenance cost estimates that were used to create the FY 1996 infrastructure and maintenance budget input, and a listing of proposed line item and general plant projects. Additionally, assumptions for various Site programs are listed to bring the Site Maintenance Plan into focus with overall Site activities. The primary mission at Hanford is to clean up the Site. In this cleanup process WHC will provide scientific and technological expertise to meet global needs, and partnership with stakeholders in the region to develop regional economic diversification. Other missions at the Hanford Site include energy research and development, and waste management and disposal activities. Their primary mission has a 30-year projected life span and will direct the shutting down and cleanup of defense production facilities and the Fast Flux Test Facility. This long-term mission requires continuous maintenance and in many instances, replacement of existing basic infrastructure, support facilities, and utilities. Without adequate maintenance and capital funding these infrastructure, support facilities, and utilities will continue to deteriorate causing an increase in backlogged work.

Risk Based Maintenance Optimization using Probabilistic Maintenance Quantification Models of Circuit Breaker  

E-Print Network (OSTI)

New maintenance techniques for circuit breakers are studied in this dissertation by proposing a probabilistic maintenance model and a new methodology to assess circuit breaker condition utilizing its control circuit data. A risk-based decision approach is proposed at system level making use of the proposed new methodology, for optimizing the maintenance schedules and allocation of resources. This dissertation is focused on developing optimal maintenance strategies for circuit breakers, both at component and system level. A probabilistic maintenance model is proposed using similar approach recently introduced for power transformers. Probabilistic models give better insight into the interplay among monitoring techniques, failure modes and maintenance techniques of the component. The model is based on the concept of representing the component life time by several deterioration stages. Inspection and maintenance is introduced at each stage and model parameters are defined. A sensitivity analysis is carried to understand the importance of model parameters in obtaining optimal maintenance strategies. The analysis covers the effect of inspection rate calculated for each stage and its impact on failure probability, inspection cost, maintenance cost and failure cost. This maintenance model is best suited for long-term maintenance planning. All simulations are carried in MATLAB and how the analysis results may be used to achieve optimal maintenance schedules is discussed. A new methodology is proposed to convert data from the control circuit of a breaker into condition of the breaker by defining several performance indices for breaker assemblies. Control circuit signal timings are extracted and a probability distribution is fitted to each timing parameter. Performance indices for various assemblies such as, trip coil, close coil, auxiliary contacts etc. are defined based on the probability distributions. These indices are updated using Bayesian approach as the new data arrives. This process can be made practical by approximating the Bayesian approach calculating the indices on-line. The quantification of maintenance is achieved by computing the indices after a maintenance action and comparing with those of previously estimated ones. A risk-based decision approach to maintenance planning is proposed based on the new methodology developed for maintenance quantification. A list of events is identified for the test system under consideration, and event probability, event consequence, and hence the risk associated with each event is computed. Optimal maintenance decisions are taken based on the computed risk levels for each event. Two case studies are presented to evaluate the performance of the proposed new methodology for maintenance quantification. The risk-based decision approach is tested on IEEE Reliability Test System. All simulations are carried in MATLAB and the discussions of results are provided.

Comparing maintenance costs of geothermal heat pump systems with other HVAC systems: Preventive maintenance actions and total maintenance costs  

SciTech Connect

Total annual heating, ventilating, and air-conditioning (HVAC) maintenance costs were determined for 20 schools in the Lincoln, Nebraska, Public School District. Each school examined provides cooling to over 70% of its total floor area and relies on one of the following heating and cooling systems to provide the majority of space conditioning: vertical-bore, geothermal heat pumps (GHPs), air-cooled chiller with gas-fired hot water boiler (ACC/GHWB), or water-cooled chiller with gas-fired steam boiler (WCC/GSB). A precursor to this study examined annual costs associated with repair, service, and corrective maintenance activities tracked in a work order database. This follow-up study examines costs associated with preventive maintenance (PM) activities conducted by the district. Annual PM costs were 5.87 {cents}/yr-ft{sup 2} (63.14 {cents}/yr-m{sup 2}) for ACC/GHWB schools, followed by 7.14 {cents}/yr-ft{sup 2} (76.86 {cents}/yr-m{sup 2}) for GHP, 9.82 {cents}/yr-ft{sup 2} (105.39 {cents}/yr-m{sup 2}) for WCC/ GSB, and 12.65 {cents}/yr-ft{sup 2} (136.30 {cents}/yr-m{sup 2}) for WCC/GHWB. The results of the two analyses are combined to produce an estimate of total annual maintenance costs, by system type, for the 20 schools. Total annual maintenance costs were 8.75 {cents}/yr-ft{sup 2} (94.20 {cents}/yr-m{sup 2}) for ACC/GHWB schools, followed by 9.27 {cents}/yr-ft{sup 2} (99.76 {cents}/yr-m{sup 2}) for GHP, 13.54 {cents}/yr-ft{sup 2} (145.49 {cents}/yr-m{sup 2}) for WCC/GSB, and 18.71 {cents}/yr-ft{sup 2} (201.61 {cents}/yr-m{sup 2}) for WCC/GHWB. It should be noted that these costs represent only the trends seen in the maintenance database of the Lincoln School District. Because of differences in the number of schools using each system type, varying equipment age, and the small total number of schools included in the study, the maintenance costs presented here may not be representative of the maintenance costs seen for similar equipment in other locations.

Kalispell Maintenance Headquarters Project : Environmental Assessment and Findings of No Significant Impact.  

SciTech Connect

The facilities needed to maintain and repair Bonneville Power Administration (BPA`s) electrical equipment in northwest Montana are currently in two locations: A maintenance headquarters at the Kalispell Substation, and a temporary leased facility south of Kalispell. The present situation is not efficient. There is not enough space to accommodate the equipment needed at each site, and coordination and communication between the two sites is difficult. Also, two sites means duplication of equipment and facilities. BPA needs a single, centralized facility that would efficiently accommodate all the area`s maintenance activities and equipment. BPA proposes to build a maintenance headquarters facility consisting of 2 to 4 single-story buildings totaling about 35,000 square feet (office spaces and workshop areas); an open-ended vehicle storage building (carport style); a fenced-in storage year; a storage building for flammables, herbicides, and hazardous wastes; and a parking lot. The facility would require developing about 6 to 10 acres of land. Two sites are being considered for the proposed project (see the attached map for locations). This report is the environmental assessment of the two options.

Safety assured financial evaluation of maintenance  

E-Print Network (OSTI)

Management decisions in complex industrial facilities usually consider both the economic and environmental aspects of the plant's performance. For nuclear power plants (NPPs), safety is also a very substantial issue. The objectives of this dissertation are to develop and demonstrate a novel useful conceptual model that could be used to allocate maintenance funds for a nuclear power plant in such a way as to meet all specified safety requirements and objectives, while achieving a high degree of economic performance. The model is based on the general theory that the reliability of a plant at any time is a function of its initial reliability and the maintenance history of the individual plant components (Smith, 1997). Such a model can assist in evaluating strategic management decisions regarding allocation of funds for nuclear power plant maintenance. It could be used as a simulation tool; various scenarios could be studied to answer "what if" questions. Simulations of this type will allow a better understanding of the relationship between maintenance, economic performance, and safety, and consequently will lead to better decision making. The novelty of this model is tied to the intimate relationship that it develops between maintenance activities at a nuclear plant, and their relationship to prescribed safety requirements and to the economic performance of that plant.

Software maintenance maturity model (smmm): the software maintenance process model  

E-Print Network (OSTI)

This paper summarizes the research work leading to a Phd thesis that addresses the assessment and improvement of the software maintenance function by proposing a maturity model for daily software maintenance activities: Software Maintenance Maturity Model (SM mm) as well as its supporting knowledge based system SM Xpert. The software maintenance function suffers from a scarcity of management models to facilitate its evaluation, management, and continuous improvement. The SM mm addresses the unique activities of software maintenance while preserving a structure similar to that of the CMMi ©1 maturity model. It is designed to be used as a complement to this model. The SM mm is based on practitioners ’ experience, international standards, and the seminal literature on software maintenance. This paper presents the model’s purpose, scope, foundation, and architecture, followed by a knowledgebased system to help software maintainers learn and use the maturity model. 1.

Decontamination and decommissioning surveillance and maintenance report for FY 1991. Environmental Restoration Program  

SciTech Connect

The Decontamination and Decommissioning (D&D) Program has three distinct phases: (1) surveillance and maintenance (S&M); (2) decontamination and removal of hazardous materials and equipment (which DOE Headquarters in Washington, D.C., calls Phase I of remediation); and (3) decommissioning and ultimate disposal, regulatory compliance monitoring, and property transfer (which DOE Headquarters calls Phase II of remediation). A large part of D&D is devoted to S&M at each of the sites. Our S&M activities, which are performed on facilities awaiting decommissioning, are designed to minimize potential hazards to human health and the environment by: ensuring adequate containment of residual radioactive and hazardous materials; and, providing physical safety and security controls to minimize potential hazards to on-site personnel and the general public. Typically, we classify maintenance activities as either routine or special (major repairs). Routine maintenance includes such activities as painting, cleaning, vegetation control, minor structural repairs, filter changes, and building system(s) checks. Special maintenance includes Occupational Safety and Health Act facility upgrades, roof repairs, and equipment overhaul. Surveillance activities include inspections, radiological measurements, reporting, records maintenance, and security (as required) for controlling and monitoring access to facilities. This report summarizes out FY 1991 S&M activities for the Tennessee plant sites, which include the K-25 Site, the Gas Centrifuge facilities, ORNL, and the Y-12 Plant.

LASER ENGINEERED NET SHAPING FOR REPAIR AND HYDROGEN COMPATIBILITY  

DOE Green Energy (OSTI)

A method to repair mismatched or damaged components using Laser Engineered Net Shaping{sup R} (LENS) technology to apply material was investigated for its feasibility for components exposed to hydrogen. The mechanical properties of LENS bulk materials were also tested for hydrogen compatibility. The LENS process was used to repair simulated and actual mismachined components. These sample components were hydrogen charged and burst tested in the as-received, as-damaged, and as-repaired conditions. The testing showed that there was no apparent additional deficiency associated with hydrogen charging compared to the repair technique. The repair techniques resulted in some components meeting the requirements while others did not. Additional procedure/process development is required prior to recommending production use of LENS.

The objectives of this partnership project were to develop a preventive maintenance checklist program, a troubleshooting system for the Vertical Turning Center (VTC)-5, an on-line manual, and to integrate these components with a custom browser that would run on the VTC-5 machine's controller and would support future internet/intranet delivery. Kingsbury provided subject matter experts from engineering, manufacturing, and technical support. They also provided photographs, schematics, and CAD drawings, which AlliedSignal Federal Manufacturing and Technologies (ASFM and T) digitized for use in the final program. Information from The Kingsbury troubleshooting experts were interviewed regarding symptoms and root causes of system malfunctions This knowledge was captured and from it, fault trees were developed. These trees were then incorporated into the EPSS as a troubleshooting tool. The troubleshooting portion of the system presents simple questions to the machine operator in order to determine the likely cause or causes of malfunctions and then recommends systematic corrective actions. The on-line reference manual, covering operations and maintenance, provides text and illustrations to the machine operator in a traditional structure, but additionally offers the capability to search voluminous amounts of technical data and retrieve specific information on request. The maintenance portion of the EPSS includes checklists that are displayed daily, weekly, monthly, and annually, as appropriate, on the VTC-5 controller screen. The controller software is unavailable for machining parts until the machine tool operator goes through and checks off all of the checklist items. This project provided the team with a detailed understanding of the knowledge and information required to produce and support advanced machine tools. In addition, it resulted in the design and construction of a prototype VTC-5 EPSS containing all the logic and interfaces necessary to integrate operations and maintenance information from other Kingsbury machine tools.

Reliability-based maintenance evaluations and standard preventive maintenance programs  

SciTech Connect

Due to recent issuance of 10CFR50.65, the U.S. Nuclear Regulatory Commission maintenance rule (Rule), and the [open quotes]Industry Guideline for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants[close quotes] prepared by the Nuclear Management and Resources Council, many utilities are undertaking review or evaluation of current preventive maintenance (PM) programs. Although PM optimization and documentation are not specifically required by the Rule, an appropriate and effective PM program (PMP) will be the cornerstone of the successful and cost-effective implementation of the Rule. Currently, a project is being conducted at the Vermont Yankee Nuclear Power Station (VYNPS) in conjunction with Quadrex Energy Services to evaluate, optimize, and document the PMP. The project began in March 1993 and is scheduled for completion in mid-1995. The initial scope for the project is the evaluation of those structures, systems, and components that are within the scope of the Rule. Because of the number of systems to be evaluated ([approximately]50), the desired completion schedule, and cost considerations, a streamlined approach to PM optimization and documentation is being utilized.

Mining Surveillance and Maintenance Dollars  

Science Conference Proceedings (OSTI)

Accelerating site cleanup to reduce facility risks to the workers, the public and the environment during a time of declining federal budgets represents a significant technical and economic challenge to U.S. Department of Energy (DOE) Operations Offices and their respective contractors. A significant portion of a facility's recurring annual expenses are associated with routine, long-term surveillance and maintenance (S&M) activities. However, ongoing S&M activities do nothing to reduce risks and basically spend money that could be reallocated towards facility deactivation. This paper discusses the background around DOE efforts to reduce surveillance and maintenance costs, one approach used to perform cost reviews, lessons learned from field implementation and what assistance is available to assist DOE sites in performing these evaluations.

Operations, Maintenance, and Replacement 10-Year Plan, 1990 -1999.  

SciTech Connect

In 1988 Bonneville Power Administration (BPA) began work on this Operations, Maintenance, and Replacement 10-Year Plan to develop a levelized program that would assure high system reliability. During the Programs in Perspective (PIP) meetings in the late summer and fall of 1988, many of the concerns to be addressed in an Operations, Maintenance, and Replacement Plan were identified. Following these PIP meetings BPA established internal work groups. During the winter and spring of 1989, these work groups developed technical background and issue papers on topics that ranged from substation maintenance to environmental protection. In addition, a customer forum group was established and met on several occasions to review work on the plan, to offer ideas and points of view, and to assure that BPA understood customer concerns. Based on recommendations from the work group reports and customer input, BPA's O M Management Team developed the draft Operations, Maintenance, and Replacement 10-Year Plan that was released for public comment during the spring of 1990. During the public review period, BPA received a number of written comments from customers and the interested public. In addition, special meetings were held with interested customers. This final Operations, Maintenance, and Replacement 10-Year Plan reflects BPA's response to customers and interested public on each topic discussed in the 10-Year Plan. The plan is a distillation of BPA's strategies to achieve a levelized program over 10 years.

Reliability centered maintenance of power transformers and circuit breakers  

SciTech Connect

At the Bonneville Power Administration (BPA), we have historically maintained high voltage equipment. Including transformers and power circuit breakers, on a time driven basis. While this has served our needs in the past, newer methods are needed to effectively maintain the power system in future years. Today aging equipment, maintenance backlogs, and budget constraints are a reality. BPA has initiated a research and development project to examine reliability centered maintenance (RCM) as an alternative to time based maintenance on high voltage equipment. Under RCM, the performance of each place of equipment is to be monitored by observing many operating parameters. For example, with circuit breakers we will observe (measure) the trip time, accumulated contact wear using I{sup 2}T, timing of the mechanism, plus several other parameters. Equipment performing below a predetermined level, or equipment having accumulated a large amount of ``usage`` will receive maintenance. The maintenance will restore full performance and preserve an acceptable service life for that piece of equipment. To develop and evaluate RCM concepts, BPA is installing a prototype system at our Alvey Substation on 4 transformers and 25 breakers.

A cask maintenance facility feasibility study  

SciTech Connect

The Oak Ridge National Laboratory (ORNL) is developing a transportation system for spent nuclear fuel (SNF) and defense high level waste (HLW) as a part of the Federal Waste Management System (FWMS). In early 1988, a feasibility study was undertaken to design a stand-alone, ''green field'' facility for maintaining the FWMS casks. The feasibility study provided an initial layout facility design, an estimate of the construction cost, and an acquisition schedule for a Cask Maintenance Facility (CMF). The study also helped to define the interfaces between the transportation system and the waste generators, the repository, and a Monitored Retrievable Storage (MRS) facility. The data, design, and estimated costs resulting from the study have been organized for use in the total transportation system decision-making process. Most importantly, the feasibility study also provides a foundation for continuing design and planning efforts. Fleet servicing facility studies, operational studies from current cask system operators, a definition of the CMF system requirements, and the experience of others in the radioactive waste transportation field were used as a basis for the feasibility study. In addition, several cask handling facilities were visited to observe and discuss cask operations to establish the functions and methods of cask maintenance expected to be used in the facility. Finally, a peer review meeting was held at Oak Ridge, Tennessee in August, 1988, in which the assumptions, design, layout, and functions of the CMF were significantly refined. Attendees included representatives from industry, the repository and transportation operations.

The impetus for such endeavors derives from the belief that the high incidence of skin cancer in the genetic disorder xeroderma pigmentosum (XP) primarily is a result of the reduced capacity of patients cells to repair UV-induced DNA damage. For assay, UV-irradiated non-replicating recombinant plasmid DNA harboring a chloramphenicol acetyltransferase (CAT) indicator gene is introduced into lymphocytes using DEAE-dextran short-term transfection conditions. Exposure to UV induces transcriptionally-inactivating DNA photoproducts in the plasmid DNA which inactivate CAT gene expression. Excision repair of the damaged CAT gene is monitored indirectly as a function of reactivated CAT enzyme activity following a 40 hour repair/expression incubation period.

Polymer nanocomposites for high-temperature composite repair  

SciTech Connect

A novel repair agent for resin-injection repair of advanced high temperature composites was developed and characterized. The repair agent was based on bisphenol E cyanate ester (BECy) and reinforced with alumina nanoparticles. To ensure good dispersion and compatibility with the BECy matrix in nanocomposites, the alumina nanoparticles were functionalized with silanes. The BECy nanocomposites, containing bare and functionalized alumina nanoparticles, were prepared and evaluated for their thermal, mechanical, rheological, and viscoelastic properties. The monomer of BECy has an extremely low viscosity at ambient temperature, which is good for processability. The cured BECy polymer is a highly cross-linked network with excellent thermal mechanical properties, with a high glass transition temperature (T{sub g}) of 270 C and decomposition temperature above 350 C. The incorporation of alumina nanoparticles enhances the mechanical and rheological properties of the BECy nanocomposites. Additionally, the alumina nanoparticles are shown to catalyze the cure of BECy. Characterization of the nanocomposites included dynamic mechanical analysis, differential scanning calorimetry, thermogravimetric analysis, rheological and rheokinetic evaluation, and transmission electron microscopy. The experimental results show that the BECy nanocomposite is a good candidate as repair agent for resin-injection repair applications.

Alkyltransferase-like proteins (ATLs) can do the same, but they lack the reactive cysteine residue that allows the alkyltransferase function, and the mechanism for cell protection has remained unknown. To address this mystery, a British-American team lead by researchers at the Scripps Research Institute recently applied a combination of x-ray structural, biochemical, and genetic studies to ATLs in the yeast Schizosaccharomyces pombe without and with damaged DNA. By showing how a process called non-enzymatic nucleotide flipping activates ATL-initiated DNA repair, their results may improve our understanding of genomic integrity and responses to DNA damage relevant to pathogens and cancer development.

Planning and care mark repair of 14-year old leak in Kuwait Oil Co. LPG tank 95  

SciTech Connect

This paper points out that the leak, which had been present for such a long time, completely saturated the perlite insulation with hydrocarbons, thus rendering the entire operation of inspection, repair, and maintenance of the inner tank a hazardous operation. It emphasizes the safety aspects, which were complicated by the saturated perlite as well as by the fact that the tank is situated in the middle of the LPG storage area with LPG tanks on either side. Tank design, making preparations, inspection, and repair are discussed. The fact that the leaking flanges were originally installed damaged, indicated the future need of tighter company quality control of all contractors work.

1999 Gordon Research Conference on Mammalian DNA Repair. Final Progress Report  

SciTech Connect

This Conference will examine DNA repair as the key component in genomic surveillance that is so crucial to the overall integrity and function of mammalian cells. Recent discoveries have catapulted the field of DNA repair into a pivotal position for fundamental investigations into oncology, aging, environmental health, and developmental biology. We hope to highlight the most promising and exciting avenues of research in robust discussions at this conference. This Mammalian DNA Repair Gordon Conference differs from the past conferences in this series, in which the programs were broader in scope, with respect to topics and biological systems covered. A conference sponsored by the Genetics Society in April 1998 emphasized recombinational mechanisms for double-strand break repair and the role of mismatch repair deficiency in colorectal cancer. These topics will therefore receive somewhat less emphasis in the upcoming Conference. In view of the recent mechanistic advances in mammalian DNA repair, an upcoming comprehensive DNA repair meeting next autumn at Hilton Head; and the limited enrollment for Gordon Conferences we have decided to focus session-by-session on particular areas of controversy and/or new developments specifically in mammalian systems. Thus, the principal presentations will draw upon results from other cellular systems only to the extent that they impact our understanding of mammalian DNA repair.

We describe the design of a tenant interface for energy and maintenance systems (TIEMS) in commercial buildings. TIEMS is designed for use by occupants (tenants) of commercial buildings. Our hypothesis is that by allowing tenants access to information from the energy and maintenance systems and by giving them some control over these systems, energy and maintenance performance can be improved. We used interviews with potential users and existing energy and maintenance databases to guide the design. Results of a field trial demonstrate the utility of TIEMS. We also describe the design of a maintenance and operations recommender (MORE). MORE uses information from computerized maintenance management systems (CMMS) and energy management and control systems (EMCS) to recommend what maintenance personnel should do in response to a maintenance service request. MORE integrates text descriptions of problems with sensor information related to the problem. After work orders are closed, MORE uses the information about what was actually done to solve the problem to learn how to improve its recommendations.

Estimation the Performance of Solar Fiber Optic Lighting System after Repairing the Glass Fiber Cables in a South Korean Residential Building  

E-Print Network (OSTI)

The solar fiber optic lighting system consists of the solar ray concentrating apparatus, the tracking control, lighting transmission and emission parts. This system was installed on a 20-storey apartment building in South Korea. Many residents had concerns about its long-term maintenance. The most common maintenance difficulties are sun tracking problems and damaged glass fiber cables. Sometimes fiber optic lighting systems should not be repaired with splices. Splicing glass fiber cables often results in decreased system efficiency and further cable damage. In this study, the cost of replacing the cables was prohibitive; hence, the drop in efficiency of the damaged cables was answered by repairing through splicing. These damaged cables were repaired by specially process of cutting and polishing. Results showed that the luminous intensity ratio improved by 0.391%, though this was still lower than the recommended guideline of 0.725%. Accordingly, on average 55% of luminous intensity was increased.

This has prompted an exploration of repair and mitigation options to prevent future degradation of the RVH. Inconel 52 and Inconel 152, which are resistant to PWSCC, have been identified as potential repair alloys for Alloy 600 type repairs, and have been evaluated with the gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) pro...

Charge transport-mediated recruitment of DNA repair enzymes  

E-Print Network (OSTI)

Damaged or mismatched bases in DNA can be repaired by Base Excision Repair (BER) enzymes that replace the defective base. Although the detailed molecular structures of many BER enzymes are known, how they colocalize to lesions remains unclear. One hypothesis involves charge transport (CT) along DNA [Yavin, {\\it et al.}, PNAS, {\\bf 102}, 3546, (2005)]. In this CT mechanism, electrons are released by recently adsorbed BER enzymes and travel along the DNA. The electrons can scatter (by heterogeneities along the DNA) back to the enzyme, destabilizing and knocking it off the DNA, or, they can be absorbed by nearby lesions and guanine radicals. We develop a stochastic model to describe the electron dynamics, and compute probabilities of electron capture by guanine radicals and repair enzymes. We also calculate first passage times of electron return, and ensemble-average these results over guanine radical distributions. Our statistical results provide the rules that enable us to perform implicit-electron Monte-Carlo simulations of repair enzyme binding and redistribution near lesions. When lesions are electron absorbing, we show that the CT mechanism suppresses wasteful buildup of enzymes along intact portions of the DNA, maximizing enzyme concentration near lesions.

Fabrication Flaw Density and Distribution In Repairs to Reactor Pressure Vessel and Piping Welds  

Science Conference Proceedings (OSTI)

The Pacific Northwest National Laboratory is developing a generalized fabrication flaw distribution for the population of nuclear reactor pressure vessels and for piping welds in U.S. operating reactors. The purpose of the generalized flaw distribution is to predict component-specific flaw densities. The estimates of fabrication flaws are intended for use in fracture mechanics structural integrity assessments. Structural integrity assessments, such as estimating the frequency of loss-of-coolant accidents, are performed by computer codes that require, as input, accurate estimates of flaw densities. Welds from four different reactor pressure vessels and a collection of archived pipes have been studied to develop empirical estimates of fabrication flaw densities. This report describes the fabrication flaw distribution and characterization in the repair weld metal of vessels and piping. This work indicates that large flaws occur in these repairs. These results show that repair flaws are complex in composition and sometimes include cracks on the ends of the repair cavities. Parametric analysis using an exponential fit is performed on the data. The relevance of construction records is established for describing fabrication processes and product forms. An analysis of these records shows there was a significant change in repair frequency over the years when these components were fabricated. A description of repair flaw morphology is provided with a discussion of fracture mechanics significance. Fabrication flaws in repairs are characterized using optimized-access, high-sensitivity nondestructive ultrasonic testing. Flaw characterizations are then validated by other nondestructive evaluation techniques and complemented by destructive testing.

WHERE MULTIFUNCTIONAL DNA REPAIR PROTEINS MEET: MAPPING THE INTERACTION DOMAINS BETWEEN XPG AND WRN  

Science Conference Proceedings (OSTI)

The rapid recognition and repair of DNA damage is essential for the maintenance of genomic integrity and cellular survival. Multiple complex and interconnected DNA damage responses exist within cells to preserve the human genome, and these repair pathways are carried out by a specifi c interplay of protein-protein interactions. Thus a failure in the coordination of these processes, perhaps brought about by a breakdown in any one multifunctional repair protein, can lead to genomic instability, developmental and immunological abnormalities, cancer and premature aging. This study demonstrates a novel interaction between two such repair proteins, Xeroderma pigmentosum group G protein (XPG) and Werner syndrome helicase (WRN), that are both highly pleiotropic and associated with inherited genetic disorders when mutated. XPG is a structure-specifi c endonuclease required for the repair of UV-damaged DNA by nucleotide excision repair (NER), and mutations in XPG result in the diseases Xeroderma pigmentosum (XP) and Cockayne syndrome (CS). A loss of XPG incision activity results in XP, whereas a loss of non-enzymatic function(s) of XPG causes CS. WRN is a multifunctional protein involved in double-strand break repair (DSBR), and consists of 3’–5’ DNA-dependent helicase, 3’–5’ exonuclease, and single-strand DNA annealing activities. Nonfunctional WRN protein leads to Werner syndrome, a premature aging disorder with increased cancer incidence. Far Western analysis was used to map the interacting domains between XPG and WRN by denaturing gel electrophoresis, which separated purifi ed full length and recombinant XPG and WRN deletion constructs, based primarily upon the length of each polypeptide. Specifi c interacting domains were visualized when probed with the secondary protein of interest which was then detected by traditional Western analysis using the antibody of the secondary protein. The interaction between XPG and WRN was mapped to the C-terminal region of XPG as well as the C-terminal region of WRN. The physical interaction between XPG and WRN links NER, (made evident by the disease XP) with DSBR, which imparts additional knowledge of the overlapping nature of these two proteins and the previously distinct DNA repair pathways they are associated with. Since genomic integrity is constantly threatened by both endogenous and exogenous (internal and external) damage, understanding the roles of these proteins in coordinating DNA repair processes with replication will signifi cantly further understanding how defects instigate physiological consequences in response to various DNA damaging sources. This ultimately contributes to our understanding of cancer and premature aging.

10 MWe Solar Thermal Central Receiver Pilot Plant maintenance experience, January 1982-March 1983  

DOE Green Energy (OSTI)

This report presents a description of the maintenance experience at the 10 MWe Solar Thermal Central Receiver Pilot Plant near Barstow, California, during the period January 1982 through March 1983. The plant systems are briefly described, and statistical data on maintenance orders, labor requirements, and maintenance costs are presented. The data presented have been extracted from Southern California Edison historical maintenance records accumulated at the plant. Pilot plant systems requiring the most maintenance activity are identified so that efforts to reduce plant maintenance costs can be properly identified. The information is analyzed for the purpose of developing a data base for general use during the economic assessment, design, and staff planning of future solar central receiver plants. However, data presented here from the Pilot Plant should not be used for direct scaling of larger power production plants. The number and size of equipment items for larger plants will not scale, the designs will vary, and the Pilot Plant includes special testing and evaluation equipment which would not be necessary in plants built for the sole purpose of power production. Data taken at the Pilot Plant during the early plant startup and operational phase shows an annual maintenance cost of approximately one perent of the recurring plant capital cost. Similar costs for recent technology steam electric generating plants are estimated to range from 1.5 to 3%. The Pilot Plant maintenance cost will not appear as favorable if based on energy produced during power production due to the small plant size and equipment intensive nature of the plant. The solar-unique systems of the plant required 45% of the total plant maintenance labor and 39% of the total maintenance cost, both percentages being lower than anticipated.

A Portable Expert System for Gas Turbine Maintenance  

E-Print Network (OSTI)

Combustion turbines for electric power generation and industrial applications have steadily increased in size, efficiency and prominence. The newest class of gas turbine-generators coming into service will deliver 150 megawatts, with turbine inlet temperatures of 2300° F. To sustain high levels of performance and reliability of this equipment, diagnostics and maintenance planning have also become increasingly important. Within the electric power industry, for example, as the overall fleet of gas turbines has aged, their annual service factor has increased to carry more of the peak load burden as reserve margins shrink. However, peaking duty requires frequent cycling with large thermal stresses that tend to shorten the life of hot section components. To assist the industry in meeting these needs, EPRI has developed The SA?VANT™ System. This unique multi-faceted portable unit will apply a broad range of expert systems in the workplace for power plant maintenance, including turbomachinery of all types, but especially for gas turbines.

software maintenance in Distributed, EVOLVing Environments  

E-Print Network (OSTI)

Distributed applications in evolving environments are typically difficult to maintain. Currently, human intervention is needed to maintain the application and adapt it to its changed environment. We need to: deploy application software on the added devices (buses), replace application software on the changed devices (e.g. to support the new advertisement display), and remove application software when no longer useful (e.g. because it requires an advertisement display which is removed). When the distributed environment becomes too large, or changes too often, manual software maintenance is no longer a feasible option. Automation is required. This paper reports on our ongoing work on dEVOLVe, a new OSGi based middleware platform which will automate some software maintenance tasks in ’distributed evolving environments’. dEVOLVe will detect changes in the distributed environment and will adapt the application accordingly. This way, the user is free from software maintenance tasks caused by the environment evolution.

CleanFleet. Final report: Volume 3, vehicle maintenance and durability  

DOE Green Energy (OSTI)

CleanFleet is a demonstration of panel vans operating on five alternative motorfuels in commercial package delivery operations in the South Coast Air Basin of California. The five alternative fuels are propane gas, compressed natural gas (CNG), California Phase 2 reformulated gasoline (RFG), methanol (M-85 with 15 percent RFG), and electricity. Data were gathered on in-use emissions, operations, and fleet economics. This volume of the final report summarizes the maintenance required on these vans from the time they were introduced into the demonstration (April through early November 1992) until the end of the demonstration in September 1994. The vans were used successfully in FedEx operations; but, to varying degrees, the alternative fuel vehicles required more maintenance than the unleaded gasoline control vehicles. The maintenance required was generally associated with the development state of the fuel-related systems. During the demonstration, no non-preventive maintenance was required on the highly developed fuel-related systems in any of the unleaded gasoline production vehicles used either as controls or as RFG test vehicles. The maintenance problems encountered with the less developed systems used in this demonstration may persist in the short term with vehicles featuring the same or similar systems. This means that fleet operators planning near-term acquisitions of vehicles incorporating such systems should consider the potential for similar problems when (1) selecting vendors and warranty provisions and (2) planning maintenance programs.

The technical and economic success of repairable PDC bits  

Science Conference Proceedings (OSTI)

Repairable PDC bits have saved operators and contractors millions of dollars in bit costs alone. The repair of steel-bodied PDC bits has been going on for over 4 years but more recently, due to technical innovations, matrix body bits are becoming repairable. DBS was concerned when starting the repairability project that the quality of a repaired bit be close to that of a new bit. Conventional thinking had it that the repaired bit would at best be slightly inferior to a new bit. However, during our initial evaluation of repaired steel-bodied bits, the authors noticed that, remarkably, the repaired bits overall drilled more footage per run at a higher rate of penetration than new bits. After over 200 bits had been run, repaired, and rerun, in every case and for every bit style the average footage and ROP were slightly higher for the repaired bit.

Energy and Technology Review: Unlocking the mysteries of DNA repair  

SciTech Connect

DNA, the genetic blueprint, has the remarkable property of encoding its own repair following diverse types of structural damage induced by external agents or normal metabolism. We are studying the interplay of DNA damaging agents, repair genes, and their protein products to decipher the complex biochemical pathways that mediate such repair. Our research focuses on repair processes that correct DNA damage produced by chemical mutagens and radiation, both ionizing and ultraviolet. The most important type of DNA repair in human cells is called excision repair. This multistep process removes damaged or inappropriate pieces of DNA -- often as a string of 29 nucleotides containing the damage -- and replaces them with intact ones. We have isolated, cloned, and mapped several human repair genes associated with the nucleotide excision repair pathway and involved in the repair of DNA damage after exposure to ultraviolet light or mutagens in cooked food. We have shown that a defect in one of these repair genes, ERCC2, is responsible for the repair deficiency in one of the groups of patients with the recessive genetic disorder xeroderma pigmentosum (XP group D). We are exploring ways to purify sufficient quantities (milligrams) of the protein products of these and other repair genes so that we can understand their functions. Our long-term goals are to link defective repair proteins to human DNA repair disorders that predispose to cancer, and to produce DNA-repair-deficient mice that can serve as models for the human disorders.

Utilities are doing too much breaker maintenance  

Science Conference Proceedings (OSTI)

Many breaker failures occur after the breaker has been torn down for maintenance because some error was made in reassembling it. Utilities now can get a better understanding of circuit breaker reliability as the result of a worldwide survey conducted by the International Conference on Large High-Voltage Electric Systems (Cigre) of the reliability of circuit breakers 63 kV and above. The most significant finding is that the rate of major failures have dropped drastically with the introduction of modern SF[sub 6] breakers (from 1.58 to 0.67 per 100 breaker-years). But the rate of minor failures - such as gas leaks, which require maintenance and add to the operating cost - has increased by 30%. Incorrect maintenance causes far fewer failures in modern breakers, simply because they have to be torn down less frequently. Only 15% as many major failures and 77% as many minor failures can be attributed to incorrect maintenance. The failure to open or close on command are still the dominant major-failure modes of circuit breakers. 4 tabs.

DNA repair in cells sensitive and resistant to cis-diamminedichloroplatinum(II): Host cell reactivation of damaged plasmid DNA  

SciTech Connect

cis-Diamminedichloroplatinum(II) (cis-DDP) has a broad clinical application as an effective anticancer drug. However, development of resistance to the cytotoxic effects is a limiting factor. In an attempt to understand the mechanism of resistance, the authors have employed a host cell reactivation assay of DNA repair using a cis-DDP-damaged plasmid vector. The efficiency of DNA repair was assayed by measuring the activity of an enzyme coded for by the plasmid vector. The plasmid expression vector pRSV cat contains the bacterial gene coding for chloramphenicol acetyltransferase (CAT) in a configuration which permits expression in mammalian cells. The plasmid was transfected into repair-proficient and -deficient Chinese hamster ovary cells, and CAT activity was subsequently measured in cell lysates. In the repair-deficient cells, one cis-DDP adduct per cat gene was sufficient to eliminate expression. An equivalent inhibition of CAT expression in the repair-proficient cells did not occur until about 8 times the amount of damage was introduced into the plasmid. These results implicate DNA intrastrand cross-links as the lesions responsible for the inhibition of CAT expression. This assay was used to investigate the potential role of DNA repair in mediating cis-DDP resistance in murine leukemia L1210 cells. The assay readily detects the presence or absence of repair and confirms that these resistant L1210 cells have an enhanced capacity for repair of cis-DDP-induced intrastrand cross-links.

Exposure Evaluation for Benzene, Lead and Noise in Vehicle and Equipment Repair Shops  

SciTech Connect

An exposure assessment was performed at the equipment and vehicle maintenance repair shops operating at the U. S. Department of Energy Hanford site, in Richland, Washington. The maintenance shops repair and maintain vehicles and equipment used in support of the Hanford cleanup mission. There are three general mechanic shops and one auto body repair shop. The mechanics work on heavy equipment used in construction, cranes, commercial motor vehicles, passenger-type vehicles in addition to air compressors, generators, and farm equipment. Services include part fabrication, installation of equipment, repair and maintenance work in the engine compartment, and tire and brake services. Work performed at the auto body shop includes painting and surface preparation which involves applying body filler and sanding. 8-hour time-weighted-average samples were collected for benzene and noise exposure and task-based samples were collected for lead dust work activities involving painted metal surfaces. Benzene samples were obtained using 3M™ 3520 sampling badges and were analyzed for additional volatile organic compounds. These compounds were selected based on material safety data sheet information for the aerosol products used by the mechanics for each day of sampling. The compounds included acetone, ethyl ether, toluene, xylene, VM&P naphtha, methyl ethyl ketone, and trichloroethylene. Laboratory data for benzene, VM&P naphtha, methyl ethyl ketone and trichloroethylene were all below the reporting detection limit. Airborne concentrations for acetone, ethyl ether, toluene and xylene were all less than 10% of their occupational exposure limit. The task-based samples obtained for lead dusts were submitted for a metal scan analysis to identify other metals that might be present. Laboratory results for lead dusts were all below the reporting detection limit and airborne concentration for the other metals observed in the samples were less than 10% of the occupational exposure limit. Noise dosimetry sampling was performed on a random basis and was representative of the different work activities within the four shops. Twenty three percent of the noise samples exceeded the occupational exposure limit of 85 decibels for an 8-hour time-weightedaverage. Work activities where noise levels were higher included use of impact wrenches and grinding wheels.

CATALYST ACTIVITY MAINTENANCE FOR THE LIQUID PHASE SYNTHESIS GAS-TO-DIMETHYL ETHER PROCESS PART II: DEVELOPMENT OF ALUMINUM PHOSPHATE AS THE DEHYDRATION CATALYST FOR THE SINGLE-STEP LIQUID PHASE SYNGAS-TO-DME PROCESS  

DOE Green Energy (OSTI)

At the heart of the single-step liquid phase syngas-to-DME process (LPDME{trademark}) is a catalyst system that can be active as well as stable. In the Alternative Fuels I program, a dual-catalyst system containing a Cu-based commercial methanol synthesis catalyst (BASF S3-86) and a commercial dehydration material ({gamma}-alumina) was demonstrated. It provided the productivity and selectivity expected from the LPDME process. However, the catalyst system deactivated too rapidly to warrant a viable commercial process [1]. The mechanistic investigation in the early part of the DOE's Alternative Fuels II program revealed that the accelerated catalyst deactivation under LPDME conditions is due to detrimental interaction between the methanol synthesis catalyst and methanol dehydration catalyst [2,3]. The interaction was attributed to migration of Cu- and/or Zn-containing species from the synthesis catalyst to the dehydration catalyst. Identification of a dehydration catalyst that did not lead to this detrimental interaction while retaining adequate dehydration activity was elusive. Twenty-nine different dehydration materials were tested, but none showed the desired performance [2]. The search came to a turning point when aluminum phosphate was tested. This amorphous material is prepared by precipitating a solution containing Al(NO{sub 3}){sub 3} and H{sub 3}PO{sub 4} with NH{sub 4}OH, followed by washing, drying and calcination. The aluminum phosphate catalyst has adequate dehydration activity and good stability. It can co-exist with the Cu-based methanol synthesis catalyst without negatively affecting the latter catalyst's stability. This report documents the details of the development of this catalyst. These include initial leads, efforts in improving activity and stability, investigation and development of the best preparation parameters and procedures, mechanistic understanding and resulting preparation guidelines, and the accomplishments of this work.

The radiographic integrated test stand (RITS-3) is a 5-MV, 160-kA, 70-ns inductive voltage adder accelerator at Sandia National Laboratories used to develop critical understanding of x-ray sources and flash radiographic drivers. On RITS-3 three pulse forming lines (PFLs) are used to drive three inductive voltage adder cavities. Each PFL contains a fast-pulse-charged, self-breakdown annular water switch that is used for initial pulse shaping and timing. Low loss in the switches combined with good synchronization is required for efficient operation of the accelerator. Switch maintenance is closely monitored over time to determine the effects of wear on switch breakdown performance.

Technical Insights for Saltstone PA Maintenance  

Science Conference Proceedings (OSTI)

The Cementitious Barriers Partnership (CBP) is a collaborative program sponsored by the US DOE Office of Waste Processing. The objective of the CBP is to develop a set of computational tools to improve understanding and prediction of the long-term structural, hydraulic, and chemical performance of cementitious barriers and waste forms used in nuclear applications. CBP tools are expected to better characterize and reduce the uncertainties of current methodologies for assessing cementitious barrier performance and increase the consistency and transparency of the assessment process, as the five-year program progresses. In September 2009, entering its second year of funded effort, the CBP sought opportunities to provide near-term tangible support to DOE Performance Assessments (PAs). The Savannah River Saltstone Disposal Facility (SDF) was selected for the initial PA support effort because (1) cementitious waste forms and barriers play a prominent role in the performance of the facility, (2) certain important long-term behaviors of cementitious materials composing the facility are uncertain, (3) review of the SDF PA by external stakeholders is ongoing, and (4) the DOE contractor responsible for the SDF PA is open to receiving technical assistance from the CBP. A review of the current (SRR Closure & Waste Disposal Authority 2009) and prior Saltstone PAs (e.g., Cook et al. 2005) suggested five potential opportunities for improving predictions. The candidate topics considered were (1) concrete degradation from external sulfate attack, (2) impact of atmospheric exposure to concrete and grout before closure, such as accelerated slag and Tc-99 oxidation, (3) mechanistic prediction of geochemical conditions, (4) concrete degradation from rebar corrosion due to carbonation, and (5) early age cracking from drying and/or thermal shrinkage. The candidate topics were down-selected considering the feasibility of addressing each issue within approximately six months, and compatibility with existing CBP expertise and already-planned activities. Based on these criteria, the five original topics were down-selected to two: external sulfate attack and mechanistic geochemical prediction. For each of the selected topics, the CBP communicated with the PA analysts and subject matter experts at Savannah River to acquire input data specific to the Saltstone facility and related laboratory experiments. Simulations and analyses were performed for both topics using STADIUM (SIMCO 2008), LeachXS/ORCHESTRA (ECN 2007, Meeussen 2003), and other software tools. These supplemental CBP analyses produced valuable technical insights that can be used to strengthen the Saltstone PA using the ongoing PA maintenance process. This report in part summarizes key information gleaned from more comprehensive documents prepared by Sarkar et al. (2010), Samson (2010), and Sarkar (2010).

New methods of repairing mis-machined components are always of interest. In this study, an innovative method using Laser Engineered Net Shape{trademark} (LENS{reg_sign}) forming was used to repair intentionally mis-machined test articles. The components were repaired and subsequently hydrogen charged and burst tested. The LENS repair did not have an adverse effect on the solid state weld process that was used to repair the components. Hydrogen charged samples failed in a similar manner to the uncharged samples. Overall, the prospects for LENS repairing similar products are favorable and further work is encouraged.

Advanced Remote Maintenance Design for Pilot-Scale Centrifugal Contactors  

Science Conference Proceedings (OSTI)

Advanced designs of used nuclear fuel recycling processes and radioactive waste treatment processes are expected to include more ambitious goals for aqueous based separations including; higher separations efficiency, high-level waste minimization, and a greater focus on continuous processes to minimize cost and footprint. Therefore, annular centrifugal contactors are destined to play a more important role for such future processing schemes. Pilot-scale testing will be an integral part of development of many of these processes. An advanced design for remote maintenance of pilot-scale centrifugal contactors has been developed and a prototype module fabricated and tested for a commercially available pilot-scale centrifugal contactor (CINC V-02, 5-cm rotor diameter). Advanced design features include air actuated clamps for holding the motor-rotor assembly in place, an integral electrical connection, upper flange o-rings, a welded bottom plate, a lifting bale, and guide pins. These design features will allow for rapid replacement of the motor rotor assembly, which can be accomplished while maintaining process equilibrium. Hydraulic testing of a three-stage prototype unit was also performed to verify that design changes did not impact performance of the centrifugal contactors. Details of the pilot-scale remote maintenance design, results of testing in a remote mockup test facility, and results of hydraulic testing of the advanced design are provided.

Cask system maintenance in the Federal Waste Management System  

SciTech Connect

In early 1988, in support of the development of the transportation system for the Office of Civilian Radioactive Waste Management System (OCRWM), a feasibility study was undertaken to define a the concept for a stand-alone, green-field'' facility for maintaining the Federal Waste Management System (FWMS) casks. This study provided and initial layout facility design, an estimate of the construction costs, and an acquisition schedule for a Cask Maintenance Facility (CMF). It also helped to define the interfaces between the transportation system and the waste generators, the repository, and a Monitored Retrievable Storage (MRS) facility. The data, design, and estimated costs derived from the study have been organized for use in the total transportation system decision-making process. Most importantly, they also provide a foundation for continuing design and planning efforts. The feasibility study was based on an assumed stand-alone, green-field'' configuration. This design approach provides a comprehensive design evaluation, to guide the development of a cost estimate and to permit flexibility in locating the facility. The following sections provide background information on cask system maintenance, briefly summarizes some of the functional requirements that a CMF must satisfy, provides a physical description of the CMF, briefly discusses the cost and schedule estimates and then reviews the findings of the efforts undertaken since the feasibility study was completed. 15 refs., 3 figs.

Proactive maintenance initiatives at Argonne National Laboratory-West  

SciTech Connect

In the late 1980`s, ANL-W Management foresaw a need to provide dedicated technical support for maintenance supervisors. Maintenance supervisors were facing increased challenges to ensure all environmental, safety, and waste management regulations were followed in daily maintenance activities. This increased burden was diverting supervisory time away from on-the-job supervision. Supervisors were finding less time for their ``mentor`` roles to ensure maintenance focused on finding and correcting root causes. Additionally the traditional maintenance organization could not keep up with the explosion in predictive maintenance technologies. As a result, engineers were tasked to provide direct technical support to the maintenance organization. Today the maintenance technical support group consists of two mechanical engineers, two electrical engineers and an I&C engineer. The group provides a readily available, quick response resource for crafts people and their supervisors. They can and frequently do ask the support group for help to determine the root cause and to effect permanent fixes. Crafts and engineers work together informally to make an effective maintenance team. In addition to day-to-day problem solving, the technical support group has established several maintenance improvement programs for the site. This includes vibration analysis of rotating machinery, testing of fuel for emergency diesel generators, improving techniques for testing of high efficiency particulate air (HEPA) filters, and capacity testing of UPS and emergency diesel starting batteries. These programs have increased equipment reliability, reduced conventional routine maintenance, reduced unexpected maintenance, and improved testing accuracy. This paper will discuss the interaction of the technical support group within the maintenance department. Additionally the maintenance improvement programs will be presented along with actual cases encountered, the resolutions and lessons learned.

Stochastic Modeling of Future Highway Maintenance Costs for Flexible Type Highway Pavement Construction Projects  

E-Print Network (OSTI)

The transportation infrastructure systems in the United States were built between the 50's and 80's, with 20 years design life. As most of them already exceeded their original life expectancy, state transportation agencies (STAs) are now under increased needs to rebuild deteriorated transportation networks. For major highway maintenance projects, a federal rule enforces to perform a life-cycle cost analysis (LCCA). The lack of analytical methods for LCCA creates many challenges of STAs to comply with the rule. To address these critical issues, this study aims at developing a new methodology for quantifying the future maintenance cost to assist STAs in performing a LCCA. The major objectives of this research are twofold: 1) identify the critical factors that affect pavement performances; 2) develop a stochastic model that predicts future maintenance costs of flexible-type pavement in Texas. The study data were gathered through the Pavement Management Information System (PMIS) containing more than 190,000 highway sections in Texas. These data were then grouped by critical performance-driven factor which was identified by K-means cluster analysis. Many factors were evaluated to identify the most critical factors that affect pavement maintenance need. With these data, a series of regression analyses were carried out to develop predictive models. Lastly, a validation study with PRESS statistics was conducted to evaluate reliability of the model. The research results reveal that three factors, annual average temperature, annual precipitation, and pavement age, were the most critical factors under very low traffic volume conditions. This research effort was the first of its kind undertaken in this subject. The maintenance cost lookup tables and stochastic model will assist STAs in carrying out a LCCA, with the reliable estimation of maintenance costs. This research also provides the research community with the first view and systematic estimation method that STAs can use to determine long-term maintenance costs in estimating life-cycle costs. It will reduce the agency's expenses in the time and effort required for conducting a LCCA. Estimating long-term maintenance cost is a core component of the LCCA. Therefore, methods developed from this project have the great potential to improve the accuracy of LCCA.

Feasibility study for a transportation operations system cask maintenance facility  

SciTech Connect

The US Department of Energy (DOE), Office of Civilian Radioactive Waste Management (OCRWM) is responsible for the development of a waste management program for the disposition of spent nuclear fuel (SNF) and high-level waste (HLW). The program will include a transportation system for moving the nuclear waste from the sources to a geologic repository for permanent disposal. Specially designed casks will be used to safely transport the waste. The cask systems must be operated within limits imposed by DOE, the Nuclear Regulatory Commission (NRC), and the Department of Transportation (DOT). A dedicated facility for inspecting, testing, and maintaining the cask systems was recommended by the General Accounting Office (in 1979) as the best means of assuring their operational effectiveness and safety, as well as regulatory compliance. In November of 1987, OCRWM requested a feasibility study be made of a Cask Maintenance Facility (CMF) that would perform the required functions. 46 refs., 16 figs., 13 tabs.
