Proposed Clean-Up System for Carbon Steel High Temperature Recirculation System

Description: It is the purpose of this document to outline a proposed addition to the previously considered clean-up systems as a possible solution for the maintenance of high purity water. A cyclone separator system has been devised in conjunction with the water clean-up of a high temperature recirculating reactor cooling system. By utilizing such a cyclone separator system, a high quality water can be obtained in a primary coolant system made up of carbon steel components without excessive clean-up costs.

Calcium Uranium(IV) Fluoride; Precipitation and Reduction to Metal

Description: Using ferrous ion in the presence of fluoride for reducing uranium(VI) to the four state, the salt calcium uranium (IV) fluoride can be precipitated from uranyl nitrate solutions. X-ray studies have shown that the precipitate is a true double salt and not a mixture of the two insoluble fluorides of calcium and uranium. The salt settles rapidly and can be either filtered or centrifuged. Waste losses during precipitation and washing were on the order of 2.0 and 0.4 per cent, respectively. These w… more

A Kinetic Study of the Fluoride Catalyzed Nitric Acid Dissolution of Thorium Metal

Description: The penetration rates of thorium metal by boiling nitric acid were measured as a function of the concentration of fluoride catalyst and of nitric acid. Dissolved thorium and aluminum were found to inhibit the reaction. Thoris exhibited penetration rates much lower than those of thorium metal. In addition to the specific rate measurements, pot type batch dissolvings were carried out to estimate plant time cycles. An empirical mathematical equation was devised which correlates the results of thes… more

Description: The absorption of the important fission products by plants is quantitatively presented as a concentration factor which is defined as the ratio of the fission product concentration found in the leaves to the fission product concentration found in the nutrient substrate. Of the fission products, the isotopes of strontium were found to be the most important by virtue of their high concentration factor, long half-life, and low maximum permissible amounts for animals. Iodine and barium follow in im… more
