Abstract:
The heat exchanger is nuclear equipment,and its shell part is a thin shell,which will endure the outer pressure 0.5 MPa in accident conditions.The calculation results of the structure buckling analysis by RCCM section ZIV is conservative.In this paper,the outer pressure buckling for the shell part of the heat exchanger is analyzed using ANSYS.The analysis results show that,comparing with the methods used in RCCM,the structure buckling analysis by finite element method is more accurate,and close to the project practice.
