Popis:	The influence of sulfur content in the range of 20 to 200 μg/g on grain growth in sintered pellets of ceramic uranium dioxide(UO2) fuel originating from the ammonium uranate (AU) process was investigated. Results indicate a strong dependence of discontinuous grain growth on sulfur content and on sintering rates. The data show that, in the absence of sulfur, normal microstructures are obtained by sintering, whereas the presence of sulfur can cause coring. A possible mechanism is proposed based on the effect of the sintering atmosphere, hydrogen.
