GAS-PRESSURE BONDING OF FUEL ASSEMBLIES
Technical Report
·
OSTI ID:4223207
A technique of bonding fuel assemblies by utilizing high gas pressure at elevated temperatures is being investigated for the preparation of Zircaloy-clad U-Zr fuel assemblies. The components to be bonded are fabricated to final size and then assembled and sealed in an evacuated container. The sealed assembly is then subjected to a high gas pressure and temperature in a high-pressure cold- wall autoclave. Plastic flow- brings the components into intimate contact, and bonding and cladding occur simuitaneously to form an integral assembly. Excellent results have been obtained by bonding 5 hr at 1550 deg F with a helium pressure of 10,000 psi. (auth)
