Abstract

In the EPR design there is a 100% MOX core with a slightly increased moderation ratio (2.5 instead of 2). Multirecycling Pu and Am in this core using a MOX fuel with enriched U (MOX-UE) was investigated and the results are presented in this paper. The principle is to compensate the degradation of the Pu quality by an increase of the U²³⁵ enrichment instead of an increase of the Pu content. To stabilize the Pu inventory, MOX-UE fuel with a 12% Pu content should produce between 25% and 28% of the energy. Adding Am to the fuel necessitates a drastic reduction of the Pu content in order to preserve a negative void coefficient and to increase the U²³⁵ enrichments significantly. The percentage of MOX-UE Pu+Am needed to stabilize the Pu and Am inventories is about 40%.
