Travel to Battelle Memorial Institute to discuss the results of subcontract research on the extended surface fuel element program and to review progress on the consolidation of Horizons` electrolytic thorium. Nickel-plated uranium samples, press-clad with 30-mil thick aluminum at 6, 10, and 15 thousand psi, have been on corrosion test for periods of 10 to 31 days. Six specimens from the 6,000 psi group have failed by undercutting after 21 to 31 days; this is another good record. Pinch welds have proved very effective as a means of sealing corrosion samples. Two 9--10 pound virgin ingots and three smaller remelts were made by consumable electrode arc melting of Horizons` electrolytic thorium. Physical and chemical data on the remelts are being obtained. Diffusion coefficients have been determined, at two sets of time-temperature conditions, for two diffusion couples of aluminum and a 0.5 w/o thorium in aluminum alloy, after high temperature annealing. The data show that the rate of interdiffusion of thorium and aluminum is very slow. These results are discussed.
