摘　　要：根据相关法规的要求,中等放射性废液贮槽间宜设置不锈钢敷面。分析了某型核电厂液体放射性废物系统流出液暂存槽间增设不锈钢覆面的必要性,对流出液暂存槽间的现状进行了详细的描述,指出了在严重事故工况下贮槽破裂后房间无法滞留放射性废液的问题。针对上述问题,给出了两种解决方案,从可靠性、成熟性及操作性的角度对比分析并确定最终方案,既保证了严重事故后流出液暂存槽间的滞留废液能力,又满足了正常运行工况下房间收集地面疏水的要求,最后对方案进行了总结。According to the requirements of relevant laws and regulations,stainless steel coating should be set in the medium radioactive waste liquid storage tank room.This paper analyzes the necessity of adding stainless steel cladding to the effluent temporary storage tank of the liquid radioactive waste system in a nuclear power plant,describes the current situation of the effluent temporary storage tank in detail,and points out the problem that the room can not retain radioactive waste after the storage tank breaks under severe accident conditions.In view of the above problems,two solutions are given,and the final solution is compared and analyzed from the perspective of reliability,maturity and operability,which not only ensures the residual waste liquid capacity of the effluent temporary storage tank after a serious accident,but also meets the requirements of the room to collect ground drainage under normal operating conditions.Finally,the solution is summarized.
