Abstract

Abstract

Spent fuel dry storage is an important method for handling spent fuel, however, the high temperature generated by spent fuel may cause great thermal stress, thereby leading to permanent deformation and damage. Therefore, it is of great significance to study the mechanical properties of storage canister module in spent fuel storage system. In this paper, the storage canister module in the spent fuel dry storage system is taken as the research object, and a 1/2 scaled model of the storage canister module is established. Based on the calculated temperature distribution of the storage canister module, the numerical study of the mechanical characteristics of the storage canister module under normal storage conditions is carried out, which provides data support for the scale test of the spent fuel dry storage system. The results show that: ①The stress in grid is high in center and low around, and there is a large shear stress in the top and bottom parts, while the overall stress of the aluminum support block is small, and there is a large stress at the junction of the canister shell and the top cover plate; ②Under the lowest ambient temperature condition, the maximum stress of the grid, the aluminum support block and the storage canister is 253.71 MPa, 89.99 MPa and 55.35 MPa, respectively. The stress of each component does not exceed the limits.
