• W4236006201 abstract "chemical processing systems are shown. The construction and engineering test status of the fuel processing plant are presented. Reactor Design and Analysis. Prellminary design parameters indicate the feasibility of a 500 Mw homogeneous research reactor using UO/sub 2/SO/sub 4/. The fuel costs for homogeneous reactors whose fuel is processed on a batch rather than a continuous basis were analyzed. Tables of data were prepared indicating the effecta of fuel isotopic concentration, the use of Li//sub 2/SO/sub 4/ additives, fission product removal, reactor operating periods, and Fu recovery on per krv power cost. The effects of Xe/sup 135/ on reactor conditions following shutdown were determined for the case of a U/sup 235/O/sub 2/SO/sub 4/, D/sub 2/O, spheri cal reactor operating at 280 deg C, assuming no fission product removal. Engineering Development. Developmental studies of ThO/sub 2/ blanket slurries were continued. Experience with ThO/sub 2/ deposits in circulation loops is tabulated; and shear diagrams, friction factors, and heat transfer characteristics are plotted. Slurry blanket system operational tests indicate satisfactory operation up to 300 deg C. Corrosion and Matertals. Studies of the corrosive effects of UO/sub 2/SO/ sub 4/ on Zircaloy, stainless steel, and Al//sub 2/O/sub were continued. The appearance of liquid phases as a function of temperature in UO//sub 2/SO/sub 4/-- Li/sub 2/SO/sub 4/, UO/sub 2/SO /sub 4/-BeSO/sub 4/, and BeSO/sub 4/-- UO/sub 3/ systems is plotted. Additional observations of pump corrosion and performance in reactor blanket loops contalning a range of ThO/sub 2/ concentrations are reported. Further attempts were made to establish the effects of slurry particle size on corrosive attack rates. Results of metallographic examinations of in- pile corrosion specimens of Zr and Ti alloys and stainless steel are tabulated and discussed. The effects of high temperatures and welding on crystalline phase changes in Zr alloys were investigated. The crystailine phase changes in H pickup in Ti, Zr, Al-Ti-V alloy, and Zircaloy upon exposure in the recombiner loop were determined. The effects of aging and temperature on Zircaloy impact strength are plotted. Chemical Engineering Revelopment. Chemical and engineering studies associated wlth HRT fuel processing are reported. In the study of Pu-producer blanket chemistry, adsorption of Pu on metals, Pu behavior in UO/sub 2/SO/sub 4/ solutions at 250 deg C, and dissolutlon of corrosion product oxides were considered. Slurries of ThO/sub 2/-U0//sub 3/-MoO/sub 3/-H/ sub 2/O were prepared and irradiated. Radiation effects and gas recombination rates for this type slurry are repcrted. Methods of particle size control in Th and U oxide preparation, and the effects of additives on oxide sedimentation rates in slurries were investigated. Supporting Chemical Research. Studies of slurry particle preparation and suspension are reported. The methods used in separating Pa/sup 231/ from Mallinckrodt waste are reviewed. (D.E.B.)" @default.
