Title: Demonstrate Ames Laboratory capability in Probabilistic Risk Assessment (PRA)

Abstract

In response to the damage which occurred during the Three Mile Island nuclear accident, the Nuclear Regulatory Commission (NRC) has implemented a Probabilistic Risk Assessment (PRA) program to evaluate the safety of nuclear power facilities during events with a low probability of occurrence. The PRA can be defined as a mathematical technique to identify and rank the importance of event sequences that can lead to a severe nuclear accident. Another PRA application is the evaluation of nuclear containment buildings due to earthquakes. In order to perform a seismic PRA, the two conditional probabilities of ground motion and of structural failure of the different components given a specific earthquake are first studied. The first of these is termed probability of exceedance and the second as seismic fragility analysis. The seismic fragility analysis is then related to the ground motion measured in terms of ``g`` to obtain a plant level fragility curve.

  • This report is a user's manual for a package of computer programs and data files to be used for probabilistic risk assessment of shallow-land burial of low-level radioactive waste. The nuclide transport pathways modeled are an unsaturated groundwater column, an aquifer, and the atmosphere. An individual or the population receives a dose commitment through shine, inhalation, ingestion, direct exposure, and/or a puncture wound. The methodology of risk assessment is based on the response surface method of uncertainty analysis. The parameters of the model for predicting dose commitment due to a release are treated as statistical variables, in order to computemore » statistical distributions for various contributions to the dose commitment. The likelihood of a release is similarly treated as a statistical variable. Uncertainty distributions are obtained both for the dose commitment and for the corresponding risk. Plots and printouts are produced to aid in comparing the importance of various release scenarios and in assessing the total risk of a set of scenarios. The entire methodology is illustrated by an example. Information is included on parameter uncertainties, reference site characteristics, and probabilities of release events.« less
  • In FY 1993, the Los Alamos National Laboratory Waste Management Group [CST-7 (formerly EM-7)] requested the Probabilistic Risk and Hazards Analysis Group [TSA-11 (formerly N-6)] to conduct a study of the hazards associated with several CST-7 facilities. Among these facilities are the Hazardous Waste Treatment Facility (HWTF), the HWTF Drum Storage Building (DSB), and the Mixed Waste Receiving and Storage Facility (MWRSF), which are proposed for construction beginning in 1996. These facilities are needed to upgrade the Laboratory`s storage capability for hazardous and mixed wastes and to provide treatment capabilities for wastes in cases where offsite treatment is not availablemore » or desirable. These facilities will assist Los Alamos in complying with federal and state requlations.« less
  • In a Probabilistic Risk Assessment (PRA) for a nuclear power plant, the analyst identifies a set of potential core damage events and their estimated probabilities of occurrence. These events include both equipment failures and human errors. If operator recovery from an event within some specified time is considered, the probability of this recovery can be included in the PRA. This report provides PRA analysts with a step-by-step methodology for including recovery actions in a PRA. The recovery action is divided into two distinct phases: a Diagnosis Phase (realizing that there is a problem with a critical parameter and deciding uponmore » the correct course of action) and an Action Phase (physically accomplishing the required action). In this methodology, time-reliability curves, which were developed from simulator data on potentially dominant accident scenarios, are used to provide estimates for the Diagnosis Phase, and other existing methodologies are used to provide estimates for the Action Phase.« less
  • In a probabilistic risk assessment (PRA) for a nuclear power plant, the analyst identifies a set of potential core damage events consisting of equipment failures and human errors and their estimated probabilities of occurrence. If operator recovery from an event within some specified time is considered, then the probability of this recovery can be included in the PRA. This report provides PRA analysts with an improved methodology for including recovery actions in a PRA. A recovery action can be divided into two distinct phases: a Diagnosis Phase (realizing that there is a problem with a critical parameter and deciding uponmore » the correct course of action) and an Action Phase (physically accomplishing the required action). In this methodology, simulator data are used to estimate recovery probabilities for the diagnosis phase. Different time-reliability curves showing the probability of failure of diagnosis as a function of time from the compelling cue for the event are presented. These curves are based on simulator exercises, and the actions are grouped based upon their operational similarities. This is an improvement over existing diagnosis models that rely greatly upon subjective judgment to obtain such estimates. The action phase is modeled using estimates from available sources. The methodology also includes a recommendation on where and when to apply the recovery action in the PRA process.« less
  • A sensitivity evaluation was conducted to assess the impact of human errors on the internal event risk parameters in the LaSalle plant. The results provide the variation in the risk parameters, namely, core melt frequency and accident sequence frequencies, due to hypothetical changes in human error probabilities. Also provided are insights derived from the results, which highlight important areas for concentration of risk limitation efforts associated with human performance. 14 refs., 28 figs., 9 tabs.
