Abstract

Abstract

Under severe reactor accidents, there is a risk of creep failure of pressure vessel due to insufficient cooling. Based on the modified θ-projection creep model, a creep model for reactor pressure vessel steel SA533B is proposed. The model can completely describe the three-stage creep process, and the simulation results are in good agreement with the experimental result creep curve. At the same time, the creep behavior under any load can be predicted by interpolation method. The model can be further used in the relevant case analysis of pressure vessel failure.
