The use of MOX fuel in commercial reactors is a means of burning plutonium originating from either surplus weapons or reprocessed irradiated uranium fuel. This requires the fabrication of MOX assemblies on an industrial scale.
The OECD/NEA Expert Group on Experimental Needs for Criticality-Safety has highlighted MOX fuel manufacturing as an area in which there is a specific need for additional experimental data for validation purposes. Indeed, integral experiments with low-moderated MOX fuel are either scarce or not sufficiently accurate to provide an appropriate degree of validation of nuclear data and computer codes. New and accurate experimental data would enable a better optimisation of the fabrication process by decreasing the uncertainties on the determination of multiplication factors of configurations such as the homogenisation of MOX powders.
In this context, the OECD/NEA Nuclear Science Committee organised a workshop to address the following topics:
1) Expression and justification of needs for critical or near critical experiments with low-moderated MOX fuels
2) Proposals for experimental programs to address these needs
3) Prospects for an international co-operative program
