Nuclear waste management has led to recycling PuO/sub 2/ into mixed oxide fuel nuclear fuel (MOX). Its manufacturing route involves a sintering process. A multiscale model is under construction in order to predict the evolution of the sample characteristics during sintering and to improve sintering conditions. The purpose of the small scale model is to(More)
Nuclear waste management has led to recycling PuO/sub 2/ into nuclear fuel (Mixed OXides). Its manufacturing route involves a sintering process. A model is under construction in order to predict the evolution of the sample characteristics during sintering and to improve the sintering conditions. The small scale model aims to simulate grain size and(More)
The oxygen to metal ratio (O/M) is directly related to oxygen potential, which strongly influences the sintering and irradiation performance of nuclear fuels. A better understanding of these two parameters is therefore of major interest. To further ascertain the correlation between O/M ratio and oxygen potential in Am-bearing MOX, several thermodynamic(More)
