IRRADIATION OF BeO-UO$sub 2$ CERAMICS
Technical Report
·
OSTI ID:4062738
Fuel pellets composed of 19 and 28 vol.% UO2/sub dispersed/ in a BeO matrix were irradiated to exposures of 2 x 10/sup 2//sup 0/ and 7 x 10/sup 1//sup 9/ fissions/cm/sup 3/, respectively. The specimen surface temperatures were approximately 15OO deg F. The UO/sub 2/ was present in the form of irregularly shaped grains approximately 115 mu average diameter. No significant change in the dimensions of the pellets or in the lattice parameters of the BeO matrix was observed. The crushing strength of the pellets and their resistance to abrasion were reduced as a result of the irradiation. (auth)
