In the framework of the joint activities of the OECD/NEA working party on the Physics of Plutonium Fuels and Innovative Fuel cycles (WPPR) and the Task Force on Reactor based Plutonium Disposition (TFRPD), an international benchmark exercise based on KRITZ UO2 and MOX critical configurations was launched in October 2000. The aim of this exercise was to investigate the capabilities of the current production codes and nuclear data librairies to analyse MOX fuelled systems and to compare the accuracy of the predictions for the MOX and UO2 fuelled configurations. Instutions from 7 countries participated in this exercise, providing 13 solutions. The report provides comparative analyses of calculated and measured results as well as intercomparions of some of the results obtained by calculations only.
