The Activation of Low-Reactivity Uranium Dioxide Particles

Description: A detailed study of the activation of low-reactivity UO2 particles toward HF by successive oxidation and reduction was carried out. The effect of repeated successive oxidation and reduction on the reactivity of the UO2 source material toward HF was evaluated by hydrofluorination.

Biological Effectiveness of Nuclear Radiations From Fission Weapons

Description: Thermal neutron measurements made on five weapons during Operation Teapot indicated that these neutrons contribute at most 2 per cent of the total neutron dose in air. However, the total fluxes were high and thermal neutrons may become important under shielding conditions and may significantly affect the responses of the film badges and certain sensitive dose detectors, especially when the neutron to gamma flux ratio is high.

Critical Masses of Oralloy Lattices Immersed in Water

Description: Certain oralloy (Oy) lattices were immersed in infinite water for determining critical masses at various low-Oy densities. Three Oy unit sizes were used. In a broad sense the experiment shows safe and unsafe conditions for handling heterogeneous Oy-water mixtures.

Determination of Aluminum in Plutonium

Description: A spectrophotometric method is described for the determination of aluminum in plutonium-aluminum alloys. The alloys are dissolved in parchloric acid and the diluted solution electrolyzed using a mercury cathode to remove any iron present which would interfere in the subsequent analysis. Then plutonium is then separated from the aluminum by precipitation as the insoluble iodate, and the aluminum determined in the supernatant solution using aluminon as a color reagent.

The Determination of Small Amounts of Thorium in the Presence of Uranium, Titanium, and Tungsten

Description: Thorium is determined in uranium alloys by means of a fluoride separation followed by a complexometric titration. A nitric of hydrochloric acid solution of the alloy is neutralized to a pH of 2.0 to 3.0 and the thorium precipitated as thorium fluoride by the addition of hydrofluoric acid and ammonium fluoride using lanthanum as a carrier.

The Determination of Vanadium and Chromium in Alloys With Uranium

Description: Two methods are described for the quantitative determination of vanadium in uranium-vanadium alloys. A procedure is also described for the quantitative determination of vanadium and chromium in uranium-chromium-vanadium alloys.

Inelastic Cross Sections and [ ] For Some Fissionable Isotopes

Description: The transmissions of neutrons through spherical shells of normal uranium, oralloy, and Pu239 are reported. One group of measurements was made using a pure fission neutron source produced by thermal neutrons. The other group of measurements was made using monoenergetic neutrons. From both groups of measurements, the inelastic scattering cross sections have been determined according to methods developed in Los Alamos Scientific Laboratory Report LA-1429 (Jaunary 1955).

Oxidation of Metals Subjected to a Linear Temperature Increase: Cubic and Logarithmic Laws

Description: The total amount of oxidation which occurs up to a given time when a metal is subjected to a continuously increasing temperature has been studied by Fasseli and coworkers. A constant rate of increase as well as the linear and parabolic oxidation laws were assumed. The present report extends the analysis to include to the cubic and logarithmic growth laws. The notation for the nth order exponential integral functions which is used here simplifies the equations and the calculations.

Status Report on the K-4 Magnetic Induction Machine

Description: Due to laboratory interest in devices capable of production of high current with short rise times in gaseous discharges (plasmas), an experimental machine has been built and tested to obtain data applicable to the design of a high gradient magnetic induction machine. This machine consists of a condenser type energy storage bank air core coupled to a toroid in which the plasma is produced. It has been used to determine circuit parameters and the effect of these parameters on the plasma.
