Abstract: Structure design and mechanical analysis of pipe support are important parts to ensure the safety of pipeline systems in
nuclear power plants. According to the loads and spatial position of a process pipe support in HPR1000 PWR, the idea of pipe
support structure design was analyzed, and the support structure was designed. The finite element model and mechanical analysis
of pipe support were established by ANSYS software. Stress assessment and rigidity check were put into effect for the pipe
support. The calculation result shows that the pipe support meets the requirements of RCC-M-2007 Design and Construction
Rules for Mechanical Components of PWR Nuclear Islands, the rigidity of the pipe support also meets the corresponding
requirements. The design idea and mechanical analysis method in this paper can provide reference for the design and analysis of
similar supports.

Key words: pipe support; finite element analysis; stress assessment; nuclear power plant
