Vital area identification (VAI) is an essential procedure for the design of physical protection systems(PPSs) for nuclear power plants (NPPs). The purpose of PPS design is to protect vital areas. VAI has beenimproved continuously to overcome the shortcomings of previous VAI generations. In first-generationVAI, a sabotage fault tree was developed directly without reusing probabilistic safety assessment (PSA)results or information. In second-generation VAI, VAI model was constructed from all PSA event treesand fault trees. While in third-generation VAI, it was developed from the simplified PSA event trees andfault trees.
While VAIs have been performed for NPPs in full-power operations, VAI for NPPs in low-power andshutdown (LPSD) operations has not been studied and performed, even though NPPs in LPSD operationsare very vulnerable to sabotage due to the very crowded nature of NPP maintenance. This study is thefirst to research and apply VAI to LPSD operation of NPP. Here, the third-generation VAI method for fullpoweroperation of NPP was adapted to the VAI of LPSD operation.
In this study, LPSD VAI for a few plant operational states (POSs) was performed. Furthermore, theoperation strategy of vital areas for both full-power and LPSD operations was discussed. The LPSD VAImethod discussed in this paper can be easily applied to all POSs. The method and insights in this studycan be important for future LPSD VAI that reflects various LPSD operational states. Regulatory bodies andelectric utilities can take advantage of this LPSD VAI method
