Irradiation of Powder Metallurgy Plates (open access)

Irradiation of Powder Metallurgy Plates

From abstract: "Four plates of uranium that were fabricated by powder metallurgy techniques and clad with 1100 aluminum by hot pressing were irradiated in the Materials Testing Reactor. Increases of about one-half per cent in length and one per cent in thickness were observed after exposure of 1600 megawatt days per ton. The surfaces of the plates remained smooth."

Coextrusion of Powder-Compact Slugs (open access)

Coextrusion of Powder-Compact Slugs

Technical report. From Abstract: "A process was developed for manufacturing aluminum-clad slugs containing UO2 or ThO2 dispersed in an aluminum matrix. In this process a mixture of the oxide and aluminum powder is cold compacted to form the billet core, which is then coextruded with an aluminum sheath to produce the clad slug."

Thermal Conductivity of Aluminum-Lithium Alloys Containing Up to 8% Lithium (open access)

Thermal Conductivity of Aluminum-Lithium Alloys Containing Up to 8% Lithium

Technical report. From Abstract: "The thermal conductivities of aluminum-lithium alloys containing up to * wt % lithium were determined at temperatures between 125 and 260ºC. The addition of lithium to aluminum sharply reduces the conductivity from 0.60 cal/(sec)(ºC)(cm) for pure aluminum to 0.22 cal/(sec)(ºC)(cm) for 2 wt % alloys; further addition linearly and more gradually decreases the conductivity to 0.16 cal/(sec)(ºC)(cm) for a 7.9 wt % alloy."

Automatic Dose Computer for Radiation Film Badges

Technical report. From Abstract: "A combination densitometer and analog computer is described which determines radiation exposure of photographic film used in personnel badges. The range of the instrument is 0 to 300 mr gamma and 0 to 300 mrad beta plus gamma. A novel phototube circuit is used to obtain logarithms directly."

Separation of Neptunium and Plutonium by Anion Exchange (open access)

Separation of Neptunium and Plutonium by Anion Exchange

Technical report. From Abstract : "The separation of neptunium and plutonium by anion exchange in nitrate solutions was studied under a wide variety of experimental conditions. A method of separation was developed that is adaptable to remote operation in the plant. In the method, Np(IV) and Pu(IV) are absorbed on an anion exchange resin from 8M nitrate solution. The column is washed with 8M HNO3 to remove contaminants; then the Pu is removed as Pu(III) by washing the column with HNO3 containing ferrous sulfamate and hydrazine. Finally, the Np is eluted with dilute HNO3."
