In recent years, nuclear pipes play a very important role in the nuclear power equipment. Nuclear pipes especially class 1 usually contain cooling coolant of high temperature and high pressure in the operating nuclear power plant. The integrality of the nuclear pipes is very important to the nuclear reactor. This paper discusses the mechanical analysis and fatigue analysis of Class 1 pipes using finite element software. The soft ware PIPESTRESS is used to analysis the Class 1 pipe system to introduce the procedure for mechanical analysis and safety evaluation. The objective is to satisfy the criteria RCC-M. The results show that the pipe can guarantee the integrity of the pipe under the conditions. The method introduced in this paper can be used as a practical method for mechanical analysis of a nuclear Class 1 pipes.
