In the framework of the IRIS-3 and IRIS-TUM irradiation programs, several full size, flat plates containing atomized (IRIS-3) or ground (IRIS-TUM) U(Mo) dispersion fuel in a aluminum matrix, with and without addition of silicon, have been irradiated in the OSIRIS reactor. The microstructural analyses of the fuels from these irradiation projects were performed at the hot laboratory (LHMA) of SCK•CEN in Mol, Belgium. Some results of the optical and scanning electron microscopy have been reported previously. Recent electron probe microanalysis results on the ground U(Mo) fuel provide further insight in the effect of adding silicon to the aluminum matrix and reveal some distinct differences between ground and atomized fuel, particularly concerning the fission gas behavior.
