Oxidation behavior of (U,Pu)C fuel materials in air-inert gas mixtures containing 400 ppm to 20% oxygen
Hyperstoichiometric (U,Pu)C samples in both powder and pelletized form were subjected to a set of experiments designed to scope the oxidation characteristics of these materials under conditions simulating exposure to a wide range of oxygen impurity in an inert atmosphere glovebox. It is demonstrated that sample oxidation rates and ''ignition'' temperature are dependent not only on particle size (or surface area) and oxygen concentration in the cover gas, but also on the rate at which oxygen is introduced into the sample environment. The conditions under which rapid oxidation and sample ''ignition'' can be induced for powder and pelletized samples are discussed, and related to processing incidents which would result in excursions in oxygen level in a glovebox atmosphere.
