Progress Report on Refining of MgX and Other Uranium-Bearing Materials

Description: From abstract: "Results are presented which suggest the possibility of satisfactorily extracting uranium from pitchblende feeds with neutral ether, without the necessity of removing sulfate, by the addition of a sufficient quantity of iron to the feed." Other factors' effects on extraction were tested and arsenic was traced throughout extraction.

Aqueous Corrosion of 2S Aluminum at Elevated Temperatures

Description: 2S aluminum corrodes uniformly in nearly pure water at rates which increase with temperature. Although normal corrosion is not extraordinarily rapid up to well over 250 degrees C, The usefulness of the material might be limited since above 200ÌŠC intergranular attack occurs, with resultant more rapid penetration and deterioration of the metal.

RBU: A Combined Monte Carlo Reactor-Burnup Program for the IBM 709

Description: RBU is a digital computer program for the detailed calculation of the neutron, reactivity, and isotopic history of a reactor in which relatively exact models of the geometry and physical processes are included to permit reliable pre dictions of fuel costs and reactor performance. The program uses the Monte Carlo method to obtain the fine structure of the neutron flux in three space dimensions and energy. Using this fine structure, cross sections are averaged over space and energy to obtain the … more

Pressure Limits of Flame Propagation of Pure Hydrocarbon-Air Mixtures at Reduced Pressure

Description: Memorandum presenting the flammability limits of 18 high-boiling hydrocarbons at reduced pressures in a closed flame tube with hot-wire ignition. Characteristic two-lobe flammability-limit curves were demonstrated by all of the hydrocarbons. The rich limit, lean limit, and flammability range were found to decrease as the number of carbon atoms increased.

An Estimation of the Explosion Hazard During Reprocessing of Metallic Uranium Fuel Elements Metallurgically Bonded to Zircaloy Cladding

Description: Through the years, considerable effort has been expended in studies of the explosive reactions sometimes observed in the dissolution of uranium-zirconium alloys in nitric acid. It has been shown (1) that such reactions result from the rapid oxidation of finely dived solids released by the preferential dissolution of the metallic matrix. The explosive portion of such solids has been identifies (1) as an intermetallic compound with the approximate composition UZr2. This compound, referred to as t… more
