摘要
Abstract
The accident analysis model for integrated small reactor was established by the code of RELAP5/MOD3.2 ,including the reactor coolant system (RCS) ,simplified secondary system and safeguard system .The small & integrated modular multi-purpose passive low-emission economical reactor (SIMPLE) is a 660 MWt (>200 MWe) inte-gral pressurized water reactor .A double-ended direct vessel injection (DEDVI) and a small break loss of coolant accident (SBLOCA ) for the direct vessel injection line were analyzed .The results show that the break and automatic depressurization system can depressurize the RCS and the coolant from accumulator and in-containment refueling water storage tank can mitigate the accident consequence of DEDVI .The results also show that the safety system can effectively lower the temperature and reduce the pres-sure of RCS ,also can prevent core overheating for SBLOCA .关键词
