Experience From Joint Research in Risk and Reliability Workstation

Abstract

KAERI (Korea Atomic Energy Research Institute ) has been participating in the Risk and Reliability (R&R) Workstation program as a form of joint research since 1993. This paper describes the experience and benefits from this joint research, as well as what KAERI has contributed to the R&R Workstation program. First, the KIRAP code, which is a probabilistic safety assessment tool developed by KAERI to improve quantification speed. Second, KAERI was able to develop its own risk monitor called Risk Monster. Third, a fast cutsets generation algorithm for risk monitors, called McFAR M, was developed to study online maintenance of the Essential Service Water (ESW) pump. Fourth, by participating in the R&R Workstation users' meeting KAERI was able to learn about new issues, and the current situation regarding U.S. nuclear regulations. KAERI's contribution to the R&R Workstation program, was to provide EPRI with the KIRAP code. In addition a localization method for the R&R Workstation software was developed.
