| 摘 要： | 分析典型的1000 MW级压水堆核电厂在高压严重事故序列下,堆芯晚期注水对压力容器失效时一回路压力的影响.分析结果表明,在开启1列稳压器卸压阀的情况下,稳压器波动管可能会在压力容器失效之前发生蠕变失效使一回路被动卸压,堆芯晚期注水不会造成一回路压力大幅增大,但波动管失效的时间和尺寸存在较大的不确定性.在开启2列或3列卸...

| Abstract: | Effect of late water injection on RCS repressurization during high pressure severe accident sequence in a typical PWR was analyzed.As the results shown,late water injection could increase RCS pres-sure when RPV failed without RCS passive depressurization.Especially in the condition of opening one PORV,RCS pressure could reach high pressure limit when RPV failed and the risk of HPME and DCH was dramatically increased.Integrity of containment could be threatened.However,in the condition of RCS pas-sive depres... |
