Techniques for Applying Sets Code Procedures to Large Fault Trees in PRA (Probabilistic Risk Assessment) Analysis.

摘要

In this paper, we describe some of the new techniques developed in the Risk Methods Integration and Evaluation Program (RMIEP) for solving large fault trees and for performing external event analysis to the same level of detail as the internal event analysis by manipulating the original internal event fault trees to include component location information. Approximations or simplifications of these techniques were used in the NUREG-1150 analyses for both internal and external events. 5 refs. (ERA citation 14:022222)
