摘　　要：池壳式布置常用于较高功率和较高压力的研究堆,堆本体采用压力壳方式,同时将压力壳浸入水池,有利于采用非能动方式导出堆芯余热,在全厂断电事故后,她有多种可能的余热导出方式。本文采用Relap5程序对某池壳式研究堆全厂断电下的应对策略进行了研究,分析了不同工况下的余热导出及堆芯安全情况,就不间断电源是否可用分别建议了事故后的应对措施。Layout of reactor vessel in a pool is usually used in high power and high pressure research reactor.For these reactors,the pressure vessel is immerged in a pool,both active and passive residual heat removal system was adopted by the reactor.The paper study the defensive strategy after station blackout accident,multi-condition was analyzed using Relap5 code,heat removal ability and safety of the core was studied,the suggestion was given to the strategy for the reactor after SBO accident.
