【摘要】 本文綜述了核电站重要設备——压水堆压力容器的应力分析和試驗结果,并参照有关国家规范拟定的强度准則,进行了应力評价。结果表明,該容器对于稳态压力和温度具有足够的强度。采用多种方法对容器所进行的对比分析,其目的不仪在于确保数据可靠,还在于試图得到一种定型的实用分析方法,以建立必要的程序系統。通过計算和試驗結果的分析比較,提出了一些看法。更多还原

【Abstract】 This paper summarizes the theoretical and experimental stress analysis results of pressure vessel of 300 MWe PWR Nuclear Power Station. Stress assessment is given with reference to relevant strength criteria. The results show that the vessel is strong enough under normal steady pressure and tempesature. Various methods were used in the stress analysis in order to cnsure reliability of the results, and to establish a practical analytical method and a program system. A comment on the stress analysis concerned is given on the basis of the comparison between the analytical and experimental resulls.更多还原
