摘要
基于对ASME规范案例N-284金属安全壳体屈曲的研究,介绍了适用于先进核电站钢制安全壳封头屈曲分析与评价的简化方法。同时,利用通用有限元程序ANSYS二次开发语言编写屈曲评定模块,并结合先进非能动核电站严重事故工况,完成钢安全壳封头屈曲安全评价。
Based on the study of ASME code case N - 284 about metal containment shell buckling design, a simplified method for buckling analysis and evaluation for steel containment head of the advanced pres- surized- water reactors is presented and described. Meanwhile, the buckling evaluation macro is devel- oped by using ANSYS parameter design language. Then the buckling safety for steel containment head of the advanced nuclear plant under the severe accident condition is estimated.
