Status Report on Pressure Resistance Weld Development for FeCrAl Thin-Wall Cladding

This report summarizes the recent development on the weld techniques of joining the thin walled FeCrAl cladding to the endplug as a part of accident tolerant fuels (ATF) program for advanced light water reactor (LWR) systems. The FeCrAl alloy has been considered as the top candidate cladding materials for ATF fuels largely due to its high oxidation resistance in high temperature steam relevant to the loss of coolant accident (LOCA) conditions. The two primary techniques for the thin-walled cladding weld development are laser beam weld (fusion based) and pressure resistance weld (solid state without melting). This report focuses on the progress made on the pressure resistance weld (PRW) development for a commercial FeCrAl alloy.
