Defense-in-depth and diversity analysis for NSSS protection system for KORI NPP unit 1
- 1. KOPEC, Taejon (Korea, Republic of)
Description
The purpose of the paper is to assess the defense-in-depth and diversity and to determine if sufficient diversity exists within the NSSS protection system to prohibit accidents and to mitigate them assuming a postulated common mode failure (CMF) in the software in KORI nuclear power plant unit 1. It was investigated in the analysis whether a diverse protective scheme against CMF was provided for each credible event described in the FSAR Chapter 15 using the methodology described in NUREG/CR-6303. In the analysis result, the vulnerabilities in diversity were eliminated by using analog modules for those parameters to exclude software common mode failure
