Engineering Development of Fluid-Bed Fluoride Volatility Processes. Part 2. Bench-Scale Investigation of a Process for Aluminum-Uranium Alloy and Stainless Steel-Cermet Fuels

“…Uranium L.ircaloy Alloy Clad with Zircaloy Developlnent work on the FBV process for U-Zr fuels was conducted in the laboratories at Brookhaven, at Fontenay~aux-Roses and Grenoble (in France), and at Argonne A cornprehenslve survey of the work at ANL with nonirradiated fueL up to 0.72 kg, in a bench-scale fluid-bed reactor, was presented in an earlier report, 18 The FBV process conditlOns recommended by s bench-scale investigatJon were, subsequently, con firmed at ANL by the pilot-scale investigations 1q made charges *Fused alumina grain rnanufactured by Norton Co ,Worcestor Mass of nonirradiated fuel subassembheso Bench~scale studIes wIth Irradiated, highly-enriche uranium-alloy fuels are also in progress at ANL and will be pre sented in a forthcoming report 20 ProceSSIng of these fuels is sImilar to that descrIbed earher for U-Al fuels except that, during the hydrochlorination, the temperatures of the fluid-bed reactor and the packed~bed flIter are maIntaIned above 331°C, the subllmatlon point of ZrCL~at 1 atm More than 99% of the ura nium In the fuel charge was consIstently recovered under a WIde variety of proce s s operatlng condItions UranIum DioXld-:, and CarbIde Dispersed In Graph,te…”
