Two hydriding--dehydriding runs were made with zirconium sponge on an engineering scale for application to retrievable tritium storage systems. The dehydriding rates were low in comparison to hydriding rates. An overall hydrogen recovery of 35% was achieved after 16 hours at 500/sup 0/C. At 600/sup 0/C, the overall hydrogen recovery was 66% after 48 hours. Hydriding rates were obtained for titanium rod at 450 and 525/sup 0/C. The maximum reaction rates for an initial system pressure of 705--709 torr were 0.026 and 0.40 Cm/sup 3/ of H/sub 2/ at STP/cm/sup 2/-min at 450 and 525/sup 0/C, respectively. Increasing the initial system pressure to 1863 torr increased the maximum reaction rate to 1.04 cm/sup 3/ of H/sub 2/ at STP/CM/sup 2/-min at 525/sup 0/C. In general, these rates are comparable to the rates obtained with zirconium sheet.
