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

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.
