Description

External reactor vessel cooling (ERVC) system, as one of the passive systems of AP1000 reactor, plays a key role for the melt in-vessel retention and prevention large-scale release of radioactive materials. In this paper the AP1000 ERVC system was modeled by RELAP5 code, simulated the physical processes of natural circulation cooling and investigated the effects of various thermal-hydraulic parameters such as decay power, subcooling, containment pressure. In addition, in this paper the simulation model of ERVC system was simplified, and proved the reasonableness of simplification by the compare of the results to the before calculations. (authors)
