Title: PRELIMINARY STUDIES OF BONDING OF BERYLLIUM-CLAD UO$sub 2$ FUEL ELEMENTS

Abstract

Gas-pressure bonding was investigated as a fabrication technique for the solid-state bonding of beryllium. Bonding parameters, surface-preparation methods, and compatibility of beryllium with UO/sub 2/ and with several container and barrier materials were studied. Beryllium-to-beryllium bonds were obtained after 2 to 4 hr at 1550 to 1650 deg F at 10,000 psi. Bonds produced with grit- blasted and abraded specimens exhibited recrystallization of grains at the original interface. The interface did not appear weaker than the parent metal during limited mechanical testing. Chromium or pyrolytic carbon coatings on UO/ sub 2/ cores prevented significant UO/sub 2/-beryllium reactions during bonding for 4 hr at 1650 deg F and 10,000 psi. Reaction products formed on the beryllium surface during compatibility experiments with other materials were easily removed by acid pickling. (auth)
