各时期核电厂ATWT缓解系统比较与分析

Comparison and Analysis of ATWT Mitigation System in Different Generation Nuclear Power Plants

摘要: 通过对各时期核电厂（二代、二代加和三代）未能紧急停堆的预期瞬态（ATWT）缓解系统进行分析和总结，将三者的ATWT缓解系统AMSAC、DAC和DAS分别从系统功能和系统结构角度进行比较与分析。结果发现它们在系统功能和系统结构上存在明显的差异，AP1000核电厂DAS与AMSAC、DAC相比在系统功能和系统结构上有一定的改进和提升。

Abstract: ATWT mitigation systems in generation Ⅱ, Ⅱ plus and Ⅲ nuclear power plants were separately analyzed and summarized, and then, from the system functions and system configuration perspective, AMSAC, DAC and DAS were separately contrasted and analyzed. The results show that there are significant differences among them, and compared with AMSAC and DAC the system function and configuration of AP1000 nuclear power plant DAS are obviously enhanced.
