High pressure vessel with hemispherical head thinner than cylinder wall is a new type ofvessel which consists ofsealing device, cylinder, hemispherical head and reinforcing ring.
The improved transient sealing analysis program for reactor pressure vessel is applied to analyze the 1/4 structure of the model under the cool and the thermal work conditions.
应用改进后的反应堆压力容器瞬态密封分析程序对压力容器模拟体1/4模型进行了冷态和热态密封分析。
