【摘要】 反应堆压力容器是主回路冷却剂压力边界屏障的一个重要设备,它具有高温、高压、高放射性的特点,对其进行密封分析是其设计过程中很重要的一环。为了验证红沿河核电工程中压力容器结构设计的密封性,采用基于Ansys软件的三维耦合热弹塑性接触密封分析技术,对红沿河核电工程的压力容器密封结构在正常与扰动工况下的密封性能进行了计算,结果表明其在正常与扰动工况下满足密封要求。更多还原

【Abstract】 Reactor pressure vessel (RPV) is an important equipment of the main coolant loop pressure boundary. Sealing analysis is crucial in its design process, because it will be subject to high temperature, pressure, and high-level radioactive characteristics. In order to verify the seal performance of the Hongyanhe Nuclear Power Project’s RPV sealing structure, the sealing effectiveness has been analyzed by the 3D elastoplastic method of ANSYS software. The results show that the RPV has been designed and manufactured in line with the sealing criteria under normal and disturbed conditions.更多还原
