Summary of Uranium Solubility Studies in Concrete Waste Forms and Vadose Zone Environments

Description: One of the methods being considered for safely disposing of Category 3 low-level radioactive wastes is to encase the waste in concrete. Concrete encasement would contain and isolate the waste packages from the hydrologic environment and act as an intrusion barrier. The current plan for waste isolation consists of stacking low-level waste packages on a trench floor, surrounding the stacks with reinforced steel, and encasing these packages in concrete. These concrete-encased waste stacks are expe… more

Refining of MgX and Other Uranium-Bearing Materials. Quarterly Progress Report

Description: Investigations on problems related to the use of MgX and other feed materials in the Plant 6 U refinery at St. Louis, Mo., have continued, with emphasis on the extraction of process feeds by neutral ether. Results of Scheibel column extraction tests wtth neutral ether on a variety of pitchblende, MgX, and V-20 soda salt feed materials indicate that the addition of Fe to complex interfering elements can reduce U losses in raffinates to lower levels than are attainable with acid ether in the abse… more

Conditions Conducive to Forming Crystalline Uranyl Silicates in SRS Evaporators

Description: The laboratory conditions under which synthetic uranyl silicates are made are almost identical to SRS evaporator conditions,with the exception of differences in sodium ion concentration. Synthetic uranyl silicates have been made only under low sodium ion concentration (less than 0.02 M), while attempts to synthesize uranyl silicates in this study in the presence of high sodium ion concentration (5.6 M), which are typical of SRS evaporators have proved unfruitful. In the presence of soluble sili… more
