Part of the Materials Science Research book series (MSR, volume 9)


Uranium dioxide exhibits a wide range of stoichiometxy with the deviation from stoichiometry, x, ranging from -0.31 to +0.24. The observation of oxygen redistribution in uranium dioxide based fuels in a nuclear reactor and the consequent effect on operational performance parameters, has prompted investigation of the migration of oxygen in a temperature gradient. Several laboratory studies have been conducted on both uranium dioxide and mixed oxide fuels [1–6].
