Assemblies containing SBR MOX fuel, fabricated in the MOX Demonstration Facility at Sellafield, were loaded into Nok's Beznau-1 reactor in 1994. The fuel was irradiated for 3 cycles to assembly average burnups of 33 MWd/kgHM and subsequently rods were extracted and sent for Post Irradiation Examination at the European Institute for Transuranium Elements. This paper presents the detailed results of this PIE investigation so far. Comparisons are also made between the PIE results and predictions from the fuel performance code ENIGMA-B to place the PIE results in context. Overall it is shown that the performance of the SBR MOX fuel is good.
