An emergency response study during multi-unit accidents

초록

Interests in multi-unit PSA have been increased after the Fukushima nuclear power plant accident. According to this situation, there has been growing necessity for multi-unit PSA as well as single-unit PSA performed mainly. Proper level 3 PSA performance is essential because total results derived from PSA are ultimately integrated in level 3 PSA. Establishment of emergency response plans is required for realistic level 3 PSA. Off-site resident protective actions consist of evacuation, sheltering, and relocation. Therefore, it is necessary to derive appropriate alternative protective actions for multi-unit level 3 PSA. Many off-site consequence assessments considering various protective alternative recommendations for multi-unit accidents were performed using MACCS in this study. Appropriate conditions for alternative protective actions in multi-unit accidents were found based on the results of this study.
