Book excerpt: Gallium present in weapons plutonium must be removed before it can be used for the production of mixed-oxide (MOX) nuclear reactor fuel. The main goal of the preliminary studies conducted at Texas A and M University was to assist in the development of a thermal process to remove gallium from a gallium oxide/plutonium oxide matrix. This effort is being conducted in close consultation with the Los Alamos National Laboratory (LANL) personnel involved in the development of this process for the US Department of Energy (DOE). Simple experiments were performed on gallium oxide, and cerium-oxide/gallium-oxide mixtures, heated to temperatures ranging from 700--900 C in a reducing environment, and a method for collecting the gallium vapors under these conditions was demonstrated.

Download or read book An Assessment of the Validity of Cerium Oxide as a Surrogate for Plutonium Oxide Gallium Removal Studies written by and published by . This book was released on 1999 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods for purifying plutonium metal have long been established. These methods use acid solutions to dissolve and concentrate the metal. However, these methods can produce significant mixed waste, that is, waste containing both radioactive and chemical hazards. The volume of waste produced from the aqueous purification of thousands of weapons would be expensive to treat and dispose. Therefore, a dry method of purification is highly desirable. Recently, a dry gallium removal research program commenced. Based on initial calculations, it appeared that a particular form of gallium (gallium suboxide, Ga2O) could be evaporated from plutonium oxide in the presence of a reducing agent, such as small amounts of hydrogen dry gas within an inert environment. Initial tests using ceria-based material (as a surrogate for PuO2) showed that thermally-induced gallium removal (TIGR) from small samples (on the order of one gram) was indeed viable. Because of the expense and difficulty of optimizing TIGR from plutonium dioxide, TIGR optimization tests using ceria have continued. This document details the relationship between the ceria surrogate tests and those conducted using plutonia.

Download or read book Kinetics of and Atmospheric Effects on Gallium Removal from a CeO2 Based Mixed Oxide Surrogate written by and published by . This book was released on 1998 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes preliminary experimental results on the kinetics of Ga removal from Ga2O3-doped CeO{sub 2-x}, a surrogate for weapons grade PuO{sub 2-x}. Ga is removed from the surrogate feedstock material using thermal techniques. An Ar-6% H2 gas was used in order to reduce the oxide to gaseous Ga2O. Experiments were done in the temperature range of 600--1,200 C as a function of time, gas flow rate, and sample geometry. Samples were analyzed through measurements of weight change, scanning electron microscopy/energy dispersive spectroscopy, x-ray photoelectron spectroscopy, proton induced x-ray emission, and direct current plasma analysis. Gallium levels were reduced by as much as 98% (130 ppm Ga residue) of that in the starting material. Studies to date have shown CeO{sub 2-x} is a very good surrogate for PuO{sub 2-x}.
