Pressurized Thermal Shock Analysis for Reactor Pressure Vessels

Science and Technology on Reactor System Design Technology Laboratory, Nuclear Power Institute of China, Chengdu, 610041, China

摘要: 依据RCC-M规范和美国NRC 10CFR50.61,对存在假想裂纹的反应堆压力容器堆芯带区进行承压热冲击分析研究。计算核电厂寿期末的基准温度,并采用承压热冲击筛选准则进行评定;计算了承压热冲击瞬态作用下裂纹尖端的应力强度因子,并按RCC-M规范进行评定。

Abstract: According to RCC-M rule and NRC 10CFR50.61,the PTS analysis was performed for the reactor pressure vessel beltline with assumed defect.The end of life reference temperature TR of nuclear power plant was calculated and assessed with PTS screening criteria.The stress intensity factors were calcu-lated under PTS transients and assessed with RCC-M Rule.
