含有弯头的核级混合管道模型计算

Calculation of Mixed Nuclear Piping Model with Elbow

采用PIPESTRESS程序,对含有弯头的核1、2级混合管道模型进行应力分析与评定,比较了单独计算和重启动计算对计算结果的影响。研究表明,单独计算的结果存在偏差,为得到符合规范要求的结果,应采用重启动计算方法。本文可以为3、4代核电厂的管道计算提供参考。

PIPESTRESS program is used to analyze and evaluate the nuclear safety class 1 and class 2 piping model with elbows,and the influence of two calculation methods of the separate calculation and the restart calculation is compared.The research shows that there is a deviation in the result of the separate calculation.In order to get the result that meets the standard requirements,the restart calculation should be adopted.This paper can provide a reference for the piping calculation of generationⅢan dⅢnuclear power plants.
