Abstract
Pressurizer relief piping was one of the most important nuclear class 1 piping in PWR nuclear power plant.Thermal stratification exist on the U shaped liquid seal section of piping between the pressurizer and three sets of safety valves,the pipeline was under cyclic thermal loading significantly,fatigue cumulative usage factor was too high.According to RCC-M code,finite element models of the local section on piping were built.Using the "mixed analysis method",fatigue analysis results were improved.The analysis result shows that the fatigue cumulative usage factor of the piping could be significantly reduced.关键词
