Fractionation of Fission Products and Heavy Elements by Volatilization Methods

Description: Technical report describing the attempt to separate the long lived fission product oxides by volatilization methods. A fractionization crucible was used. The fractionations give a fair idea of the relative volatilities of the longer lived fission products and also of the degrees of separation of the plutonium oxide or oxides from the fission products.

The Charge on Uranium(VI) in Acid Solution

Description: Abstract. The distribution coefficient of U(VI) between perchloric acid solutions and benzene solutions of TTA has been measured as a function of the acidity. It was possible to interpret the data in terms of the charge on the U(VI) species present in the aqueous phase. The experiments indicate that U(VI) exists as an ion charge +2 at acidities from 0.1M to 2.5M. In the interpretations of the distribution data, it was necessary to know the acidity coefficient of the uranyl chelate in the benzene solution. This was determined by measurement of the solubility of the compound UO2K2 - xH2). The activity coefficient of UO2K2 was found to decrease rapidly as the concentration of TTA in the benzene phase increased above 0.1M. This is probably due to the formation of a species involving more than two TTA molecules per U(VI)

The Dissolution of Thorium Metal and Thorium Dioxide in HNO3 - HF and HNO3- ( NH4 ) 2 SiF6 Mixtures

Description: Abstract. A satisfactory method has been found for dissolving thorium metal and thorium oxide in heat-treated 25-12 stainless steel vessels without excessive corrosion of the vessels. The dissolution medium consists of strong HNO3 containing a small amount of fluoride or fluo-silicate. the fluoride required has no harmful effects on a subsequent solvent-extraction step for a separation of uranium isotopes from the dissolved thorium.

Crystal Structures of Some Uranium Compounds : a Summary from the Ames Laboratory

Description: Introduction. Some forty different uranium compounds have now been given diffraction study at Ames. Reports of these investigations are scattered in the Project literature; many have been reported in a sentence or two as a note along with chemical or metallographic reports. To make the results of this crystal structure work more available this summary of the Ames work has been compiled. (A similar summary has already been published from the Chicago laboratory.)

Electrolytic Production of Uranium from Solutions of its Tribromide in Fused Salts

Description: Abstract. the electrodeposition of uranium metal, in the form of tree-like deposits, from molten strontium halide baths is described. Under the best conditions studied, approximately 40% recovery is attained. Freedom from side-reactions of the reduced uranium with anode products and/or refractory materials, and high cathode current densities appear to be essential to the success of the process. the refining of uranium under similar conditions appears to occur quite readily, with approximately 50% current efficiency. The preparation of UI3 is also described.

Preparation of Carrier Free Zr-Cb Tracer, Problem Assignment No. 263-X61C, Progress Report

Description: Technical report abstract. A rapid procedure for the preparation of very pure carrier-free Zr and Nb tracer involves the chloroform extraction of the cupferrides of Zr and Nb activities from process solutions. Zr and Nb form very stable chloroform soluble cupferrides in acid solutions (CK-993) and are separated from other fission elements almost quantitatively to yield pure mixture of Zr and Nb activity. A minimum of operations is required and the method is easily adaptable to remote control.

The Extraction Method of Purification of Uranyl Nitrate

Description: Technical report. Three extractions of a diethyl ether solution of uranyl nitrate with small portions of water are effective in removing rare earths, as is shown by radio-gadolinium and radio-europium tracer experiments. A study of representative ethers, alcohols, ketones, and esters showed that diethyl ether and a mixture of 85% ethyl methyl ketone with 15% xylene are the best solvents for the extraction.

Separations Chemistry, Quarterly Progress Report, January-March 1954

Description: "Scale-up work on high temperature fuel recovery processes has progressed to the point where the (high temperature) vacuum furnace for several operations to the hot cells has been completed and tested under operating conditions. Small scale experiments on high temperature methods for processing molten irradiated uranium fuel have been made with spent X-10 fuel slug pieces. The results of direct Pu evaporation, treatment with fused fluorides and oxide scavenging were every similar to those found with tracer experiments."

Heat Generation in Thermal Shields

Description: "Heat production resulting from the absorption of gamma ray photons in thermal shields and the leakage of neutrons and photons from ferritic thermal shields are investigated. The gamma rays considered arise from three types of reactor radiation -- thermal neutrons, fast neutrons, and core and reflector gammas. The energy spectra of the fast neutron leakage and absorption have been investigated in some detail because of the significant contribution of fast neutrons to the heating of the concrete biological shield."

Technical and economic potentials of shale oil production by nuclear explosives

Description: "In the following report, a new technology is discussed which was first proposed in 1959, but which has been developed mainly since 1964; the in situ production of oil from shale by large underground retorts created by nuclear explosives. The first part of the present report describes this new process; the second part gives an analysis of the United States and the world endowments with crude oil resources and oil shale deposits and finally, the third part deals with expected cost estimates of this new technology as compared with present crude oil prices and potential costs of conventional shale oil production."

Airborne Radiometric Survey in Northern New Jersey and Southeastern New York

Description: Abstract: "An airborne radiometric survey of the pre-Cambrian Highlands of New Jersey and New York, and Triassic Newark Basin located in 14 radiometric anomalies in the Highlands. No commercial deposit of uranium discovered. Ground checks revealed that most anomalies were caused by large masses or residual boulders of slightly radioactive granitoid gneiss."
