Nine clad and unclad composite specimens consisting of glass fibers containing 50 wt% U/sub 3/O/sub 8/ dispersed in a Type 1100 aluminum matrix were irradiated by Battelle at a temperature of 100 deg C to depletion burnups of 17 to 24% % of U/sup 235/ and to fast-neutron (> 1 Mev) exposures of 1 8 x 10/sup 20/ to 2.6 x 10/sup 20/ nvt. The specimens appeared unchanged by the irradiation environment. Swelling as determined by measurements of dimensions and densities was of the same order of magnitude as reported for alloy fuels which experienced similar irradiation exposures. Fission-gas release could be accounted for by the recoil mechanism. The ultimate strengths and elastic moduli were increased and the ductility as determined from elongation measurements did not change appreciably. Metallographic examination did not reveal any evidence of change in the microstructure, and evidence of fission recoil in the matrix was not observed. (auth)
