摘要
四种事件可导致堆芯冷却剂流量下降。计算了这四种事件发生后堆芯内DNBR的分布,并从中找出最小DNBR。结果表明,冷却剂泵轴卡死事件的最小DNBR为最低,堆芯中部分燃料元件的最小DNBR低于限定值1.3。
Four events could result in a decrease of core coolant flow rate. The DNBR distributions incore are calculated for these events, and the minimum DNBR is found out from theirdistributions. The results show that the lowest DNBR occurs in the event of the coolant pump ro-tor seizure, and the minimum DNBR of some of fuel elements in core falls below the limiting value1. 3.
