Postirradiation examinations were performed on element G-3, from the GCFR F-1 series of mixed-oxide elements, after 2.6 at. % burnup in EBR-II. The 20% cold-worked Type 316 stainless steel clad G-3 element was irradiated as an encapsulated element using a stainless steel thermal barrier to achieve peak cladding temperatures of 690/sup 0/C at a peak power of 14.4 kW/ft. The maximum diametral increase of the element was 0.2% ..delta..D/D/sub 0/. The volatile fission products were found just above the top of the fuel column and in a gap between the bottom and next higher fuel pellet. Annular pellets were used in the element, and at 2.6 at. % burnup, the central hole was closed by fuel material at both the top and the bottom of the fuel column. Fission-product attack of the cladding was minimal; a uniform matrix attack of only 0.3 mil was found along most of the length of the fuel column.
