  • Reliability-Centered Maintenance (RCM) is a process used to determine what must be done to ensure that any physical asset continues to do whatever its users want it to do in its present operating context. There are 7 basic questions of RCM: (1) what are the functions of the asset; (2) in hwat ways does it fail to fulfill its functions; (3) what causes each functional failure; (4) what happens when each failure occurs; (5) in what way does each failure matter; (6) what can be done to predict or prevent each failure; and (7) what should be done if amore » suitable proactive task cannot be found. SNL's RCM experiences: (1) acid exhaust system - (a) reduced risk of system failure (safety and operational consequences), (b) reduced annual correctiv maintenance hours from 138 in FY06 to zero in FY07, FY08, FY09, FY10 and FY11 so far, (c) identified single point of failure, mitigated risk, and recommended a permanent solution; (2) fire alarm system - (a) reduced false alarms, which cause costly evacuations, (b) precented 1- to 2-day evacuation by identifying and obtaining a critical spare for a network card; (3) heating water system - (a) reduced PM hours on fire-tube boilers by 60%, (b) developed operator tasks and PM plan for modular boilers, which can be applied to many installations; and (4) GIF source elevator system - (a) reduced frequency of PM tasks from 6 months to 1 year, (b) established predictive maintenance task that identified overheating cabinet and prevented potential electrical failure or fire.« less

  • Sandia National Laboratories has monitored NTS since 1960 in an ongoing effort to obtain prompt yield estimates. The net evolved over several years to its present layout which includes five stations distributed around the Test Site. Each station consists of short-period and wideband (0.1 to 10 Hz) instruments which are recorded on analog tape. Presently the data acquisition system is undergoing a transformation from the analog scheme to a digital system. Over the years, techniques used for the yield estimates have been refined in both areal and master event comparisons with +- 25 percent error estimates. With the new digitalmore » system, some new automated methods will be attempted to reduce the uncertainties in the yield estimates by using a larger statistical base and perhaps new analytical methods. 3 figures.« less
  • Sandia`s High Performance Computing Environment requires a hierarchy of resources ranging from desktop, to department, to centralized, and finally to very high-end corporate resources capable of teraflop performance linked via high-capacity Asynchronous Transfer Mode (ATM) networks. The mission of the Scientific Computing Systems Department is to provide the support infrastructure for an integrated corporate scientific computing environment that will meet Sandia`s needs in high-performance and midrange computing, network storage, operational support tools, and systems management. This paper describes current efforts at SNL/NM to expand and modernize centralized computing resources in support of this mission.
