摘　　要：对比分析了3种典型的乏燃料贮存池冷却方案。在现有方案基础上,综合考虑安全性、经济性及系统可实现角度,提出了6种改进的乏燃料贮存池冷却方案。经过对比,确定最佳方案是采用双吸回水管线,3列冷却回路,2列支持系统进行配置。并对第3列的冷却水泵采用交叉供电技术进行安全强化,将第3列热交换器作为设备冷却水系统非安全公共用户进行冷却。初步定性与定量分析评价表明,该优化方案在满足乏燃料贮存池冷却安全要求的前提下,具有较高的经济性。Three typical cooling schemes of spent fuel storage pool are compared and analyzed.On the basis of the existing scheme,the optimization idea is established from comprehensively considering the safety,economy and system achievable.Six different cooling schemes for spent fuel storage pool are proposed.After preliminary comparison and selection of multiple schemes,the best scheme is determined.The best scheme adopts double suction and return water pipelines,three rows of cooling circuits and two rows of supporting systems.The cooling water pump of the third train is provided with cross power supply technology to enhance safety.The third train of heat exchanger is used as a public user of the equipment cooling water system for cooling.Analysis and demonstration show that the scheme has high economic efficiency under the premise of meeting the cooling safety requirements of spent fuel storage pools.
