摘　　要：反应堆压力容器作为反应堆冷却剂系统的高压承压边界设备,其密封性能直接影响反应堆运行的安全性和可靠性。为了提高反应堆压力容器密封性能,系统分析了压力容器顶盖法兰锥段、顶盖法兰厚度和密封面倾角三方面结构形式变化对密封性能的影响,并获得了上述结构参数的优化设计方向,为提高压力容器密封性能和后续密封结构设计提供了指导。In order to improve the sealing behavior of reactor pressure vessel（RPV）, the effects of pyramidal section of RPV head flange, head flange thickness and sealing angle on the sealing behavior were studied. The optimization design of these structural parameters was obtained. The conclusion is useful for improving the sealing behavior and guiding the future sealing structure design.
