摘要
采用RELAP5/MOD3.3程序对某游泳池式反应堆的全厂断电事故工况进行计算,对堆内冷却剂流动逆转过程进行了模拟计算,并对全厂断电事故下堆芯漏流和组件间流动等相关参数对流动逆转的影响进行了深入分析。结果表明,该反应堆在失去全部强迫流动的情况下,能形成足够的自然循环流量,以导出堆芯余热,燃料组件不会发生破损。
The RELAP5/MOD3.3 code was adopted to compute the SBO accident condi‐tion of a swimming pool reactor .The coolant flow reversal process was calculated ,and the influence of parameters of the flow between the core leakage and components on the flow reversal in the SBO accident condition was analyzed .The calculated results show that in the situation the reactor loses all forced flow ,the residual heat of the reactor can be removed by the natural circulation flow , and the fuel subassembly will not be damaged .
