Irradiation and post-irradiation evaluation of a "hot-spot" FBR fuel pin
A long-term study of the behaviour of FBR mixed oxide fuel, (U,Pu)O(2), under operating power cycling conditions has been performed in the High Flux Reactor (HFR) at Petten. The series of experiments, named KAKADU, is part of a more general FBR programme. One of the KAKADU fresh fuel pins, containing by chance a single higher enriched pellet amongst a 550 mm long column of lower enriched pellets, has recently been irradiated at the HFR. The expected hot-spot fissile power was calculated using transport and diffusion codes. The irradiation carrier used to irradiate the fuel pin was designed to measure in-pile the heat produced by the pin. The fuel pin after irradiation was examined by gamma-scanning spectrometry and the results compared with both calculations and in-pile power measurements. The irradiation history, the pre-irradiation calculations, and the comparison with the PIE results are presented and discussed.
