OPTIMIZATION OF CERAMICS FOR NUCLEAR FUEL AND WASTE FORM APPLICATIONS

PDF Version Also Available for Download.

Description

We have used atomistic computer simulations and ion beam irradiations to examine radiation damage accumulation in oxides and nitrides. We have developed contour energy maps for oxides via computer simulations, to predict the effects of structure and chemical composition on radiation-induced atomic disorder, defect migration, and swelling. Ion irradiation damage experiments have been performed on fluorite and pyrochlore-structured oxide ceramics, as well as alkali halide-structured nitrides, to examine trends and to test the predictions from computer models. This presentation will examine both theoretical predictions and experimental results regarding radiation damage behavior in ceramics intended for nuclear fuel and waste form ... continued below
