FeCrAl-ODS stainless steel cladding with Al has been developed to improve oxidation resistance for accident tolerant fuel of LWRs. The strength of weld part may decrease due to growth of fine oxide particles, when the weld method with fusion is used for the end cap joining of FeCrAl-ODS stainless steel. For FeCrAl-ODS stainless steel cladding for fast reactors, the pressurization resistance welding (PRW) mood which is solid-state welding has been developed by an atomic organization. It is reported the results of joining tests that applied the PRW method about a FeCrAl-ODS stainless steel.
