Preparation of U233
Technical report. The object of the research is to determine the procedure and equipment for the preparation of U233 on a semi-works scale. The general proposed procedure is that thorium carbonate in aluminum cans will be irradiated with pile neutrons. The Pa233 resulting from neutron absorption the Th232 and the decay of Th233 will be extraction from 99% of the thorium and the natural U in thorium by MnO2 precipitations. The Pa233 will then be allowed to decay to U233 which in turn will be isolated from the remaining Th and partially decayed Pa233 by ether extraction.

The Determination of T at the Dropping Mercury Electrode in Hex Plant Ammonia and Peroxide Decantrates
Inroduction: "A study of the literature, particularly the work done by R. Strubl, I.W. Kolthoff and S.B. Smith, indicated that a polargraphic method for the estimation of T could be devised which would not sacrifice reasonable accuracy for rapidity. Work was begun with the intention of developing such a method."

Complexing Agents for the Solvent Extraction of Uranium from Thorium. I. The Use of Thiocyanate in the Extraction of Uranium. II. The Use of Antipyrine in Solvent Extraction
Abstract. In the first section of this technical report a new method of extracting uranium from thorium nitrate solution is discussed. This method consists of extracting an aqueous solution of thorium nitrate, nitric acid, sodium sulphate, and potassium thiocyanate with hexone. By this procedure, using an equal volume of hexone it is possible to extract 83 percent of the uranium while only 0.3 percent of the thorium is extracted. other experiments show that even greater separations are possible. In the second section of this report the use of antipyrine in solvent extraction procedures is discussed. Experiments are described in which 90 percent of the uranium is extracted while the thorium is extracted to the order of 3 to 5 percent.

A Rapid Method for Determination of Water in TO₃
Summary: A set of conditions is described for a ten minute determination of water in TO₃ by ignition and absorption of the evolved water in magnesium perchlorate. Complete conversion to T₃O₃ is obtained under these conditions, so that total loss on ignition and total T (plus non-volatile impurity) content may also be obtained. It has been found unnecessary to employ Cu foil to prevent interference by nitrates, which may be present with a nitrate/water ratio as high as 5, and in an amount that does not exceed 100 mg.

Tabulation or Ore Reserves and Past Production for the Uranium-Vanadium Region of Colorado, Utah, New Mexico, and Arizona
The tabulations on these pages include all of the known areas in Colorado, Utah, New Mexico, and Arizona having economically important uranium-vanadium deposits of the type which are generally referred to by the terms roscoe-lite and/or carnotite. Though similar deposits are known to exist in other areas they are to be viewed as being little more than mineralogical curiosities.

Decomposition of Water at High Temperatures and Pressures Under Reactor Irradiation
Partial abstract: "The investigation of the high temperature and pressure dissociation of water under irradiation was undertaken by the Power Pile Division of Oak Ridge National Laboratory in an effort to determine the degree of importance of the phenomenon with respect to the design of a high temperature water-cooled power reactor. Theory and past experimentation indicate that net steady-state dissociation is determined by the rates of the dissociation and recombination reactions under the imposed conditions, the dissociation rate being essentially a function of flux and the recombination rate essentially a function of temperature" (p. 3).

Preparation of Ductile Zirconium: Summary of Thermodynamic Data
Abstract: A summary of thermodynamic calculations for zirconium halides is given. Data indicates that the iodide is the most promising of the halides for arc dissociation and that good recoveries of zirconium should be obtainable provided dissociation is carried out at reduced pressure.

Geology and Ore Deposits of Mesa V, Lukachukai District, Arizona
From abstract: Mesa V of the Lukachukai area is capped by Morrison sediments which dip gently eastward from the mountains to the mesa tip, where the strata are tilted sharply to the opposite dip by the Lukachukai monocline. The Salt Wash of Mesa V contains ore outcrops which indicate favorable intensity of mineralization at one horizon along a 2000-foot outcrop interval. Other scatted exposures indicate the existence of ore under much of the mesa surface.

Bismuth Casting and Canning : (Information Report)
Introduction: The experimental work at Mound Laboratory on bismuth casting and the sealing of aluminum irradiation containers is an outgrowth of the bismuth recovery project. Since the recovered bismuth contains residual activity it is necessary that the bismuth be processed to the point that no contamination will result from shipment or any subsequent operations required to prepare the bismuth for irradiation. In order to satisfy these requirements the work here has consisted of investigating methods of preparing the bismuth slugs in the shapes required and of mechanically sealing the aluminum container.
