Uranium was successfully cast at temperatures as high as 1900 to 2000 deg C in crucibles made from CeS, CeS/sub 1.38/, ThS, ThS/sub 1.75/, and ThU/sub 0.7/S/sub 2/ with the sulfur pickup in all cases less than 0.15 wt.%, in some cases at low temperatures being less than 0.005%. A summary of actual sulfur absorption for different experimental temperatures and crucible types is given. The effect of the molten mixture of U and UBr/sub 3/(Br/U =2) upon some sulfide refractories was investigated. The results indicate that only ThS/sub 2/ and divalent sulfides like ThUS/sub 2/, US, ThS, etc., would withstand the U--UBr/sub 3/ mixture. Uranium may be separated from metal salt mixtures (CaCl/sub 2/, SrBr/ sub 2/, BaI/sub 2/, etc.) by distillation of the salt and fusion of the U in a sulfide crucible. (auth)

Data acquired form the sampling of Yakima River water-t Tests is presented. The sampling took place on June 24, 1947. The samples were analyzed for ph value, alkalinity, chlorine, harness, NH(sub 3), NO(sub 3), biological oxygen demand, dissolved oxygen, and turbidity.

Data acquired from the sampling of Columbia River water July 24, 1947, is presented. The water was analyzed for temperature, hardness, turbidity, dissolved oxygen, chlorine, ph value, NO{sub 3}, NH{sub 3}, total solids, and alkalinity.
