A fourth out-of-pile Xe/sup 133/ release experiment was performed using 2-mil iron --chromium foils impregnated with a fission-product concentration of 1.67 x 10/sup 13/ fission recoils per cm/sup 2/. The data show that temperature and fissionproduct concentration affect the amount of Xe/sup 133/ released in the initial burst. Two experiments were performed to determine the feasibility of using a static system for studying fission-gas release. In the solid-fission- product diffusion studies, results were obtained on the distribution of Ce/sup 141/ in the first diffusion couple. In three in-pile experiments, measurable amounts of all fission gases and significant amounts of Xe/sup 133/ and I/sup 131/ were released at temperatures approashing 1200 deg C from the surfaces of tubular specimens loaded with UO/sub 2/. As a result of the experiments it was concluded that irradiation to 1.67 x 10/sup 13/ fission per cm/sup 2/ induces dislocations. Bubbles were formed when the irradiated specimen was subsequertly annealed at 800 deg C and higher. The concentration of bubbles increased with increasing annealing temperature. It was found that etch pits can be produced by cathodic vacuum etching, (M.C.G.)
