Abstract

The results of a transmission electron microscopy investigation of atomised and ground U(Mo) dispersion fuel in an aluminum matrix, with and without the addition of silicon, irradiated in the OSIRIS reactor in the framework of the IRIS-3 and IRIS-TUM irradiation programs, are discussed. The effect of the addition of Si and the different production methods on the fuel behavior, as revealed by optical microscopy, scanning electron microscopy and electron probe microanalysis, were reported previously. Also the TEM investigation reported here reveals small differences in the structure of the amorphous interaction layer, the matrix and the fuel kernels.
