摘要

Based the reactor pressure vessel supporting of CPR1000,EPR,AP1000,a kind of reactor pres-sure vessel supporting was designed,which was used solid element and contact element mode to carry out finite element stiffness and stress calculation.The stiffness and stress calculation result of reactor pressure vessel supporting is precision.The demand of dynamics analysis is satisfied.The stiffness and stress calcu-lation of reactor pressure vessel supporting may be applied to the stiffness and stress calculation of reactor pressure vessel supporting related to different reactor core.%基于 CPR1000、EPR、AP1000反应堆压力容器支承，设计了一种反应堆压力容器支承，反应堆压力容器支承采用实体单元建模和接触单元的有限元算法模式，对反应堆压力容器支承进行了刚度和应力计算，反应堆压力容器支承刚度可用于核岛主设备动力学分析，反应堆压力容器应力分析和评定用于校验核岛主设备的安全性。反应堆压力容器支承刚度和应力计算方法可应用于新开发堆芯其它核岛主设备。
