ABSTRACT
During 1998, the emphasis of our activities was focused mainly on target fabrication. Successful conversion requires a reliable irradiation target; the target being developed uses thin foils of uranium metal that can be removed from the target hardware for dissolution and processing. This paper describes successes in (1) improving our method for heat-treating the uranium foil to produce a random small grain structure, (2) improving electrodeposition of zinc and nickel fission fragment barriers onto the foil, and (3) showing that these fission fragment barriers should be stable during transport of the targets following irradiation. A method for quantitatively electrodepositing uranium and plutonium contaminants in the 99Mo was also developed. Progress was also made in broadening international cooperation in our development activities.
