Studies were made on the behavior of a laboratory-scale vessel constructed from INOR-8 and used in a cyclic manner to dissolve Zircaloy-2 and uranium with hydrogen fluoride, followed by volatilization of the uranium with fluorine. Current flowsheet specifications for initial salt composition, temperature, and gas flow were simulated as closely as possible. Weighable corrosion coupons of INOR-8 along with specimens of four other candidate alloys were also tested. The results indicate considerable promise for INOR-8 as a material of construction for a single-vessel hydrofluorinator-fluorinator. The alloy was resistant at welded areas and was not subject to pitting attack. Corrosion on the vessel wall was relatively low, whereas the attack on the coupons was much higher because of intergranular effects. Results for HyMu-80 and Alloy 79-4 (Ni-- Fe) rated both alloys higher than INOR-8. L'' nickel was rated lowest because of a more damaging type of intergranular attack that took place. (P.C.H.)
