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。 This paper summarizes the stress analysis and test results of PWR pressure vessel, which is an important equipment of nuclear power station, and evaluates the stress with reference to the strength criterion formulated by relevant national standards. The results show that the container has sufficient strength for steady-state pressure and temperature. The comparative analysis of the containers using a variety of methods does not aim at ensuring data reliability, but rather at trying to get a stereotyped practical analytical method to establish the necessary procedural system. Through the analysis and comparison of calculation results and test results, some opinions are put forward.
