Safety analysis of bleed-and-feed operations for Maanshan power plant

[[abstract]]Thermal-hydraulic calculations using RELAP5/MOD2 are performed to simulate the responses of the Maanshan pressurized water reactor (PWR) power plant when the secondary heat sink is lost. The loss of heat sink transient of primary interest in this study is the loss of off-site power coincident because it is one of the risk-dominant sequences leading to core damage for the Maanshan PWR power plant. The major purpose of this study is to identify the effectiveness of the bleed-and-feed (B&F) operation in mitigating the consequences of the event. Therefore, both with and without B&F, calculations are performed to investigate the system responses under different assumptions[[fileno]]2060134010048[[department]]工程與系統科學
