摘要:
本文采MELCOR程序,以某船用压水堆为研究对象,分析了冷却剂主管道冷管段中破口失水事故,将所得结果与该船用堆的安全分析报告进行了比对,验证了MELCOR在计算设计基准事故时的准确性。并针对安注方式、停泵时间对事故后果的影响进行了分析,对预测事故进程、缓解事故后果具有重要意义。

Abstract:
In this paper, MELCOR code was applied to analyze the break loss of coolant accident occurring at the cold leg in the main pipe, taking the ship reactor for the object of the research. And the results were compared with the safety analysis report for the ship reactor, which proved the accuracy of the calculation for design basic accident (DBA) by MELCOR. The consequences of the accident was analyzed according to the safety injection manner and the pump stopping time, which is important for predicting the accident progress and alleviating the consequence of the accident.
