基于RCC-M与ASME的核2/3级管道应力评定比较
Comparision between RCC-M and ASME for Stress Evaluation of Nuclear Safety Class 2/3 Pipes
摘要
Abstract
RCC-M Design and Construction Rules for Mechanical Components of PWR Nuclear Islands and ASME American Society of Mechanical Engineers are widely used in China. They are similar specifications with differences. It discusses the stress analysis and evaluation methods for nuclear safety class 2/3 pipes, summarizes the requirements of RCC - M and ASME about stress evaluation and compares the differences. Such as the application of PIPESTRESS for the evaluation of stress, respectively according to RCC - M and ASME, shows that the total stress calculation results is closely related to stress increase coefficient and stress index. RCC - M standard focuses on the influence of pressure, and ASME standard focuses on the influence of gravity and accidental loading. When the internal pressure is lesser, ASME is relatively safer. When the internal pressure is bigger,and the gravity and accidental loading is lesser,RCC - M is relatively safer.关键词
