船用核动力装置小破口冷却剂丧失事故处理研究

Research of Processing Rules of SBLOCA in Marine Nuclear Reactor

应用仿真分析软件对船用核动力装置小破口冷却剂丧失事故进行计算分析,对事故发生后采取的两种事故处置方式进行对比分析,结果表明,采取低压保护停堆的事故处置方式更为合理有效。建议对原事故处理规程作进一步验证、修改,以提高事故处理的有效性。

Simulation analysis software was applied to analyze SBLOCA in marine nuclear reactor. Two kinds of processing methods were compared and analyzed. The simulation results indicated that the processing method of low pressure protection reactor shutdown is more reasonable and effective. Further check and modification on original processing rules were suggested in order to raise the effectiveness of accident processing.
