为配合秦山核电厂安全分析的评审工作和进一步开发RELAP5程序功能。我们利用程序RELAP5/MOD1对秦山厂承受未能停堆的预期瞬变(ATWS)的能力作了分析。ATWS为超设计基准事故,故采用了下列真实假定和半保守假定,即初始堆功率为1035MW,无旁通时主蒸汽隔离阀于事故后10s关闭,有旁通时,如压力低于41.8×
In line with the Qinshan Nuclear Power Plant safety assessment review and further development of RELAP5 program features. We used the program RELAP5 / MOD1 to analyze the ability of Qinshan to withstand the anticipated transient (ATWS) failure. ATWS is an over-design basis accident, so the following true assumptions and semi-conservative assumptions are used: the initial stack power is 1035MW and the main steam isolation valve is closed 10s after an accident without by-pass. If the pressure is lower than 41.8 ×
