MOX fuel quality and reprocessing requirements

Description

The BN MIMAS fuel manufacturing process relies on the dilution in free flowing UO2 of a micronized master blend containing up to 30% of PuO2. This allows to produce industrial amounts of MOX fuel with a good quality level, as illustrated by resintering results as well as weld contamination measurements. While this fuel is completely soluble in 10M HNO3, kinetics limitations appear when testing entire pellets at 5.5M molarity. These kinetic effects can be virtually eliminated by testing mid-cleaved pellets in non boiling acid, thereby confirming that the dissolution characteristics of MOX fuel are identical to those of UO2. During the reprocessing of modern MOX fuels, one should therefore not expect a more difficult dissolution than with UO2 fuel. (author). 4 refs, 5 figs, 2 tabs
