摘要
核级冷水机组是第三代核电站通风系统中的重要设施。采用有限元分析方法,针对该系统设备在异常工况(OBE)和事故工况(SSE)下的动力特性进行计算,依据RCC-M 2007对该系统设备的整体及局部构件进行强度评定。结果表明,在事故工况下该核级冷水机组吊架均能够满足相关规范的要求。
The nuclear water chiller is an important facility of ventilation system in the 3rd nuclear power plants.The dynamic characteristics of this facility in the system are calculated under abnormal(OBE)and accident(SSE)conditions using finite element analysis method,respectively.Based on RCC-M 2007,the strength evaluation on the overall and parts is conducted.The results show that the hanger frame for nuclear water chiller under accident condition can satisfy the requirements of relevant specifications.
