The LEONIDAS program is aimed at the qualification of the U(Mo)-Al(Si) dispersion fuel for the use in high power conditions. The first experiment of the program, called E-FUTURE, was performed to select the Si concentration and fuel plate heat treatment parameters for further qualification. It consisted of the irradiation of 4 distinct (4% and 6% Si, 2 different heat treatments) full size, flat fuel plates in the BR2 reactor (470 W/cm² peak BOL power, ~70% peak burn-up). After the irradiation, the E-FUTURE plates were examined non-destructively and found to have blistered in the high burn-up positions. The destructive post-irradiation examinations (PIEs) of these plates are expected to yield further insight in the cause of this blistering and the underlying mechanisms related to the fuel-matrix interaction. The examinations include scanning electron microscopy (SEM) and electron probe microanalysis (EPMA).
