摘　　要：针对国际原子能机构定义的电功率300MW以下的小型核电机组,本文较为完整地梳理了国内外研究机构主要开发的小堆,对于各型号小堆专设安全配置的特点,进行了用于缓解事故的合理分析。结合上海核工程研究设计院(SNERDI)研发的CAP200紧凑型小堆的特征,提出有效缓解非丧失冷却剂事故、丧失冷却剂事故和安全壳的专设配置措施,梳理挑战其专设配置的卡关事故,开展定量事故评价,确保CAP200紧凑型小堆专设安全配置可保证反应堆堆芯和安全壳的完整性。Aiming at the small nuclear power unit with electric power below 300 MW defined by the International Atomic Energy Agency,this paper makes a relatively complete research on main small reactors developed by domestic and foreign research institutes,and as for the engineered safety feature(ESF)characteristics of each type of small reactor,some reasonable analyses are carried out to alleviate the accidents.Combined with CAP200 compact reactor features developed by SNERDI/SPIC,China,this paper puts forward some effective measures to alleviate non-loss-of-coolant accident(Non-LOCA),loss of coolant accident(LOCA) and containment pressure.And to comb these limited accidents that challenge the ESF,this paper carries out some quantitative accident evaluation,to ensure that the ESF of CAP200 compact reactor has been designed to make sure the integrity of the reactor core and containment.
