Spent Nuclear Fuel (SNF) Canisters are large welded stainless steel structures without post-weld heat treatment, possibly leaving large welding residual stresses (WRS). For CISCC assessments for SNF canisters, the estimation of the weld residual stress accurately is very important because tensile stress can make crack initiate. In this paper, the welding procedure for the SNF canisters is simulated through a FE analysis. Two-dimensional FE WRS analysis is performed for both longitudinal welding and circumferential welding. To simulate the welding procedure, heat analysis and stress analysis are conducted separately. The results are compared with the experimental mock-up canister WRS data conducted at the Sandia National Laboratories. It seems that FEA could sufficiently confirm the experimental data.
