Probabilistic Risk Assessment Course Documentation. Volume 1. PRA (Probabilistic Risk Assessment) Fundamentals.

摘要

The full range of PRA topics are presented, with special emphasis on systems analysis and PRA applications. Systems analysis topics include system modeling such as fault tree and event tree construction, failure rate data, and human reliability. The discussion of PRA applications is centered on past and present PRA-based programs such as WASH-1400 and the Interim Reliability Evaluation Program, as well as on some of the potential future applications of PRA. The relationship of PRA to generic safety issues such as station blackout and Anticipated Transient Without Scram (ATWS) is also discussed. In addition to system modeling, the major PRA tasks of accident process analysis, and consequence analysis are presented. An explanation of the results of these activities and the techniques by which these results are derived forms the basis for a discussion of these topics. An additional topic presented in this course is the topic of PRA management, organization, and evaluation.
