摘　　要：为了补充非能动余热排出系统运行过程中蒸汽发生器二次侧流体的损失量,设置了补水箱。采用RELAP5程序进行建模分析,评估不同补水箱初始水装量对非能动余热排出系统运行造成的影响。结果表明,设置补水箱有利于建立蒸汽发生器内部长期的稳定运行状态;补水箱初始水装量越高,在补水阶段对非能动余热排出系统的换热能力抑制效应越明显,但补水结束后的长期阶段,由前期补水对非能动余热排出系统运行所造成的影响不大。The make-up tank is set to compensate the fluid loss in steam generator during the passive residual heat removal system（PRHR） operates.Using RELAP5 code,several cases with different water inventory are estimated to find out the influence to PRHR.The result shows that the make-up tank is beneficial to establish long steady state in steam generator.And more water inventory in make-up tank would reduce heat transfer through PRHR when make-up tank injects water to steam generator.But this injection has little influence on the system operation in long term.
