Title: The Frequency of Incipient Fires at the Savannah River Site

Abstract

Fire is a significant hazard in most industrial and nuclear facilities. As such it is important that adequate safeguards be provided to ensure a responsible level of safety. In determining this level of safety it is necessary to know three key parameters. These are the frequency of the incipient fire, the probability that a fire will grow from the incipient stage to cause the potential consequence, and the potential consequences (i.e., losses) from an unwanted fire. Consequence predictions have been modeled and evaluated extensively and can be readily confirmed by comparison with historic loss records. These loss records can also provide significant insight into the probability that given a fire it grows to create a defined consequence. The other key parameter, frequency, is the focus of this report. this report determines an alternative method for estimating Savannah River Site (SRS) building fire frequencies as a function of floor area to the linear method previously used. The frequency of an incipient fire is not easily derived from existing fire loss records. This occurs because the fire loss records do not make reference to the sample population. To derive an initiating frequency both the number of events (incipient fires) and the populationmore » (number of buildings and years in service) must be known. this report documents an evaluation that estimates the frequency of incipient fires in industrial and nuclear facilities. these estimates were developed from the unique historical record that has been maintained at the Savannah River Site.« less

  • The overall objective of the Integrated Demonstration Project for the Remediation of Organics at Nonarid Sites at the Savannah River Site (SRS) is to evaluate innovative remediation, characterization, and monitoring systems to facilitate restoration of contaminated sites. The first phase of the demonstration focused on the application and development of in situ air stripping technologies to remediate sediments and groundwater contaminated with volatile organic compounds (VOCs). The second phase focused on the enhancement of the in situ air stripping process by adding selected nutrients to stimulate naturally occurring microorganisms that degrade VOCs. The purpose of the third phase was tomore » evaluate the use of heating technologies [radio frequency (rf) and ohmic heating] to enhance the removal of contamination from clay layers where mass transfer is limited. The objective of this report is to document pretest and post-test data collected in support of the rf heating demonstration. The following data are discussed in this report: (1) a general description of the site including piezometers and sensors installed to monitor the remedial process; (2) stratigraphy, lithology, and a detailed geologic cross section of the study site; (3) tabulations of pretest and post-test moisture and VOC content of the sediments; (4) sampling and analysis procedures for sediment samples; (5) microbial abundance and diversity; (6) three-dimensional images of pretest and post-test contaminant distribution; (7) volumetric calculations.« less
  • The objective of the seismic reflection and side scan sonar survey is to determine the location, aerial extent, and depth of burial pits situated along the reservoir bottom of L Lake, Savannah River Site, SC. The results will be used in the overall characterization of L Lake by providing continuous profile line coverage of the bottom and subbottom sediment structure along the entire length of the project area. The results are also intended to supplement previous scientific information obtained from soil samples, aerial photography, and radiometric studies. Resultant information will be used as input for an Environmental Impact Statement ofmore » the site. Overall, the seismic reflection data will provide better descriptions of variations in the actual subbottom conditions and help identify the differing sediment layers. The side scan sonar will help identify the location of the burial pits and any other features on the bottom of the reservoir. A 3.5 kiloHertz (kHz), high resolution subbottom profiling system and an EG&G Model 260 side scan sonar system were used to meet the primary objectives of the investigation.« less
  • This report has been prepared in response to the request by the House Appropriations Committee to address the permanent isolation and containment/removal of the contaminants associated with the seepage basins at the Savannah River Site (SRS). Many of the activities regarding groundwater monitoring and status referred to in this report will be discussed in detail in a companion report on the Groundwater Monitoring Program at the SRS (WSRC-RP-89-889). Seepage Basins are broadly defined as excavated, unlined earthen basins designed to receive and store, treat, or recharge various liquid waste streams. Not included in this report are basins containing only non-hazardous,more » non-radioactive constituents, such as ash basins. Fifty-four basins are discussed in this report, forty of which are inactive. Five of the remaining fourteen active basins are coal pile runoff basins, one is an ash basin that also receives coal rejects, and the remaining eight are reactor seepage basins. The Department of Energy--Savannah River (DOE-SR) has notified the South Carolina Department of Health and Environmental Control (SCDHEC) of its intent to apply for National Pollution Discharge Elimination System (NPDES) Permits for the direct discharge of disassembly basin purge water. One the permits are issued the reactor basins will be taken out of service. All of the basins discussed in this report will be remediated under Federal and/or State regulatory environmental programs. 43 figs., 6 tabs.« less
  • During the first five years of its contract with the Department of Energy, Westinghouse Savannah River Company was paid over $130 million in fees to manage and operate the Savannah River Site. Fees paid to Westinghouse steadily increased over the five year period. For example, fees paid for the last six months of this five year period were over three times as large as fees paid for the first six months. The purpose of this inspection was to review the Department`s annual negotiation of total available fees with Westinghouse, and to examine the reasons for the growth in fees overmore » this five year period. The review disclosed that, after Fiscal Year 1989, the Department used an increasing number of fee bases in calculating Westinghouse Savannah River Company`s fixed-fee-equivalents from the maximum fee schedules within the Department of Energy Acquisition Regulation. The authors found that the Department had significantly increased the percentage of the dollar value of subcontracts being placed in Westinghouse`s fee bases for fee calculation purposes. They found that the Department had effectively increased Westinghouse`s fixed-fee-equivalents by approximately $3 million in both Fiscal Year 1993 and 1994 to, in large part, fund an unallowable employee incentive compensation program. They found that Westinghouse`s total paid fees for the five year period increased significantly over what they would have been had the terms resulting from the original competitive negotiations been maintained. The authors recommended that the Deputy Assist Secretary for Procurement and Assistance Management require that changes in either the number or composition of fee bases used in calculating fees from the maximum fee schedules be submitted to the Department`s Procurement Executive for approval.« less
  • Westinghouse Savannah River Company (WSRC) is responsible for managing and operating the Savannah River Site through a contract with the US Department of Energy (DOE). This responsibility includes providing accounts payable services for processing vendor invoices. The objective of the audit was to determine if refunds received from subcontractors were processed and recorded in accordance with DOE orders. For 6 of 10 refunds, WSRC did not follow the guidance provided by DOE Orders 2200.6 or 2200.4. Specifically, WSRC did not credit the originally charged accounts for the projects or request exception to the DOE orders from the Controller.
