Capabilities of probabilistic risk assessment modeled on a micro-computer
Responsibility for the Safety Issue Prioritization program is assigned to the Safety Program Evaluation Branch in the Office of Nuclear Reactor Regulation. The program ranks the importance of reactor safety issues using quantitative measures of benefits and costs associated with the resolution of an issue along with qualitative factors. Because of the large number of issues to be analyzed in the ranking process, a procedure was developed that would permit each issue to be analyzed with a level-of-effort amounting to two man-weeks of labor. Existing risk, cost, and dose information are used in the analysis whenever possible. Existing probabilistic risk assessments (PRAs) have been used in evaluating the change in public risk that would result from resolution of an issue. This paper briefly describes the issue analysis procedure and how the micro-computer programs are used in following the procedure. Next is a list of the PRAs that have been modeled and a discussion of how the micro-computer programs model the PRAs. Finally the advantages and the potential applications of these programs are described.
