Background: Modularization is one of characteristics of AP1000 nuclear power plant

however

the challenge of large module lifting should be met.Purpose: An analysis method for large module lifting has been studied in this paper.Methods: Based on ANSYS software and steel design code of America

the finite element analysis of CA01 structure module in AP1000 nuclear power plant was conducted.Results: The analysis results show that stress and deformation meet the requirements of codes and construction when the temporary brace is properly set in CA01 module.The maximum stress can be found in the juncture of wall

and maximum deformation occurs at the corner of CA01 module.Conclusions: Proper temporary brace is important to the lifting of structure and maximum stress or deformation usually occurs at irregular locations of structure.And it is necessary to perform detail analysis before structure lifted.
