Peroxide-Inhibited Decontamination Solutions for Carbon Steel and Other Metals in the Gas-Cooled Reactor Program. Progress Report, November 1959-July 1962

Description: A search for solutions suitable for dissolving uranium dioxide powder or lumps and yet noncorrosive enough to be used for decontaminating the carbon steel EGCR charge and service machines resulted in the development of buffered oxalate solutions of controlled temperature and pH, with hydrogen peroxide added to act as corrosion inhibitor, UO/sub 2/ oxidizer, and decontamination aid. Hydrogen peroxide acts either as a corrosion promoter or inhibitor, depending on factors such as its concentration… more

CHEMICAL TECHNOLOGY DIVISION, CHEMICAL DEVELOPMENT SECTION C, PROGRESS REPORT ON SEPARATIONS CHEMISTRY AND SEPARATIONS PROGRESS RESEARCH FOR JANUARY-JUNE 1963

Description: Cesium Recovery from Ores. Adaptation of the phenol extraction (Phenex) process to the recovery of cesium from ore leach liquors continued to show promise. In roast-leach tests, 98 to 99% of the cesium was dissolved from pollucite ore by roasting the ore at 800 deg C with 1.8 parts of Na/sub 2/CO/sub 3/ plus 1.2 parts of NaCl and leaching with water. More than 99% of the cesium was recovered from the leach liquor and separated from other alkali metals by extracting with 4-sec-butyl-2-( alpha -m… more

ELECTROLYSIS AND EXTRACTION OF SOME LANTHANONS FROM AQUEOUS ELECTROLYTES WITH LITHIUM AMALGAM

Description: Phase transfer of Pr by electrolysis at a lithium amalgam cathode was found to be linear with time for fixed electrolysis conditions. The rate of electrolysis of Pr decreased with increasing lithium citrate concentration. Extraction of Pm from Pm--Gd mixtures with saturated lithium amalgam was found to vary with virtually any change in electrolyte composition. The Pm extraction was first order with respect to Pm concentration, but the extraction rate decreased with increasing excess citrate con… more
