摘要
开发了对核电厂乏燃料贮存水池进行热工水力分析的ＲＥＴＲＡＮ模型，按照最大热功率工况，即在乏燃料贮存水池中装满乏燃料组件（其中包括换料期间刚卸出的全堆芯燃料组件）的条件下用ＲＥＴＲＡＮ模型来评估乏燃料贮存水池冷却系统的冷却能力，并进行了几个假想方案的瞬态计算和校对计算。利用ＲＥＴＲＡＮ模型来评估乏燃料贮存水池稳态和瞬态的热工水力安全分析既方便，又精确，还可用于申请许可证的计算和估算水池的温度分布。
A detailed RETRAN model has been developed for the Spent Fuel Pool(SFP) thermohydraulic analysis. The cooling capacity of the existing SFP system has been evaluated for the 'largest heat load case', i. e. full core discharge and fully loaded spent fuel assemblies. Several transient scenarios and benchmarking were simulated. RETRAN model of nodal calculations is convenient and accurate in thermo-hydraulic analysis of SFP either on steady-state or transient conditions, and can be used for licensing applications as well as best estimate of SFP temperature.
