Abstract

The objective of the LEONIDAS project (joining SCK•CEN, ILL, CEA and AREVA-CERCA) is to perform a common program for the qualification of the U(Mo) dispersion LEU fuel. The first experiment, called E-FUTURE, has tested in BR2 4 full size fuel plates made of U(Mo) atomized powder dispersed in an Al matrix with Si addition (4 and 6 % Si) at a maximum heat flux of 470 W/cm². The mean and maximum burnup reached were respectively about 48 % and 70 % 235U without cladding failure. The non destructive Post Irradiation Examinations have shown a local abnormal swelling in the highest burnup region, but with a positive evolution from 4 % to 6 % Si. The results of these detailed non-destructive analyses are also given at this conference. A new experiment, called E-FUTURE II, with higher Si contents in the matrix has been planned and defined in close collaboration with the US partners in order to pursue the performance validation of U(Mo) dispersion fuel. This new program will help to select the optimal fuel plate characteristics for the subsequent BR2 mixed curved fuel element irradiation test. The progress and the perspectives of the LEONIDAS project are described in this paper.
