Abstract Scope Dry storage canisters used for spent fuel storage are typically sealed with fusion welding. To improve the longevity of these welds, it is proposed to treat the exposed weld surface with shot peening (SP), laser shock peening (LSP), and ultrasonic impact peening (UIP). Peening has consistently shown improved fatigue and stress corrosion cracking resistance. The objective of this work is to understand the effect SP, LSP, and UIP has on the metallurgical properties of fusion welded AISI 304L SS samples. Scanning electron microscopy and electron backscatter diffraction revealed evidence of grain refinement across the treated surface with UIP showing the greatest amount of deformation. Transmission electron microscopy analysis is performed on different peened samples to examine the extent of severe plastic deformation and amorphization (if any) across the treated surface. This work is supported by the US DOE Nuclear Energy University Program (NEUP), grant DE-NE0008957.
