摘要
在安全壳地坑过滤器纤维层形成的过程中,颗粒和部分纤维材料穿过过滤器进入下游的安全注入系统(RIS)/安全壳喷淋系统(EAS)流道,核安全监管单位要求对此展开评估,确定碎渣对于过滤器下游设备的影响。以秦山核电二期扩建工程为例,使用评估文件WCAP-16406中推荐的通用方法,对压水堆核电厂中地坑过滤器下游(堆芯外)设备的堵塞和磨损影响进行相应的计算和分析。
During the generation of the thin bed on the containment sump Strainer, the particular debris and the fiber debris with the small size will pass though the strainer and go into the Safety Injection System （RIS）/Containment Spray System （EAS） flow path. The debris effect on the downstream equipment should be evaluated according to the requirement of the nuclear supervisory authorities. The general method which recommended by evaluation document WCAP-16406 is used in QINSHAN Phase II Extension Project, the calculation and analysis for the blockage and wear evaluations on the downstream effect （ex-core） in PWR are performed.
