The plutonium produced during the operation of commercial nuclear power plants or that has become available from the dismantlement of nuclear weapons needs to be properly managed. One important contribution to the management process consists in validating the calculation methods and nuclear data used for the prediction of power in systems burning mixed-oxide (MOX) fuel. Another important contribution is the improved modelling of MOX fuel behaviour in such systems.

Within the framework of the NEA Expert Group on Reactor-based Plutonium Disposition, a fuel modelling code benchmark test for MOX fuel was initiated, with in-pile irradiation data on two short MOX rods provided by the OECD/NEA Halden Reactor Project. This report summarises the in-pile data and fuel characteristics, and presents the calculation results provided by the contributors.
