Report containing ongoing projects and experiments undertaken by the Oak Ridge National Laboratory's Molten-Salt Reactor Program.

Report discussing information relative to the pyrophoricity of uranium for the purpose of reactor core fire safety. The report includes physical and chemical properties of uranium.

Study carried out to determine a suitable reactor system or systems for the testing of water, gas, and liquid-metal cooled fuel assemblies.

Report describing a method of fitting "a weighted least square polynomial of order n to a set of m observation points" in order "to satisfy the need for a general curve fitting scheme" (p. 1).

From summary: "Report discussing the beta-gamma dosage rate at the surface of a natural uranium disc. Measurements were taken using a Ryerson electrometer and an extrapolation ionization chamber."

Report of experimentation on mice of exposure to daily doses of gamma radiation at two rates and the resultant damage.

Abstract: An IBM-650 computer has been used to calculate series terms required for the area analysis of Doppler-broadened neutron cross section resonances according to the formulation of G. M. Roe.

Introduction: The object of this test work was to determine the practicability of a two-stage leach using ion-exchange as the method of uranium concentration.

From abstract: General expressions relating product stream compositions to the operating conditions of countercurrent stagewise extraction columns are derived by an inductive method, and the conversion of the general equations to ones involving the particular case of constant extraction factor is demonstrated. For comparison, the derivation of simple column equations by the use of finite difference equations is included.

From abstract: Results of a reconnaissance geochemical survey of the Rice Lake Quadrangle, Wisconsin are reported. Field and laboratory data are presented for 518 groundwater samples, 540 stream sediment samples, and 533 stream water samples.

From abstract: Results of a reconnaissance geochemical survey of the San Antonio Quadrangle , Texas are reported. Field and laboratory data are presented for 781 groundwater samples 541 stream sediment samples, and 331 stream water samples.

From abstract: Results of a reconnaissance geochemical survey of the Iron Mountain Quadrangle, Michigan; Wisconsin are reported. Field and laboratory data are presented for 479 groundwater samples, 369 stream sediment samples, and 389 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.

From introduction: "This investigation was undertaken with the general objective of determining whether uranium core could be sheathed with aluminum by an extrusion-cladding process. The ultimate objective of this work was to determine the feasibility of extrusion cladding flat plates of uranium."

The following report proposes various methods in injecting and heating in mirror machines, using high-energy ion beams.

From introduction comments: The present analysis is intended to examine the relations for "adiabatic" injection in general from a different point of view.

This report follows a study that deals with a portion of the ternary diagram previously analyzed, namely the boundary curves which separate the central area of two coexistent liquid phases from the two border stripe representing one-phase liquid systems.

The following document presents designs and blueprints to the bubble-cap column built to replace a nitric acid concentrator.

The following report provides measurements of the crystalline structure of neptunium metal.

Abstract: "A method is described for determining moisture on uranium and uranium oxides. This method should also be applicable to solid samples which, when heated, do not decompose to form water or liberate a substance which will react with Fischer's reagent. The method should be especially applicable to samples which are insoluble in alcohol or Karl Fischer reagent under normal titration conditions, or which will themselves react with the reagent. The amount of moisture on uranium and uranium oxide was found to be 0.02% except when the oxide was found to be 0.02% except when the oxide source was uranyl sulfate. In this case, the moisture content was found to be 0.1%. Modifications of the procedure and apparatus are presented for improving the accuracy and shortening the time necessary for the determination."

From abstract: "An investigation of the radiation stabilities of aqueous solutions of sodium ethylenediamine tetraacetate and sodium acetate was made using a 3000-curie Co⁶⁰ source...A study of the behavior of the standard-size Beckman type glass pH electrodes in a solution containing 0.36 curie of Ce¹⁴⁴-Pr¹⁴⁴ activity per milliliter showed the useful electrode life to be of the order of two to eight days."

This report provides fundamental equations and maps to calculate neutron behavior in a spherical cavity.

The following report describes an experiment on the aluminum nitrate process for the conversion of tuballoy tetrafluoride to tuballoy peroxide and the solutions resulting.

The following report discusses the operation of the nuclear research reactor at the University of Michigan, as well as the maximum credible accident to the reactor.
