Release of volatile fission products from uranium dioxide [electronic resource]
Post-irradiation anneal experiments have been used to determine the release of iodine and tellurium from lightly irradiated UO₂ samples maintained at stoichiometry. The applicability of the equivalent-sphere model of diffusion to release of fission gases has been tested. Diffusion coefficients and a...

| 520 | 3 | |a Post-irradiation anneal experiments have been used to determine the release of iodine and tellurium from lightly irradiated UO₂ samples maintained at stoichiometry. The applicability of the equivalent-sphere model of diffusion to release of fission gases has been tested. Diffusion coefficients and activation energies have been evaluated. The diffusion coefficient of ¹³²Te at 1400°C was found to be of an order-of-magnitude larger than that of ¹³¹I. This result may be of importance for an understanding of the pellet-cladding interaction and for a better evaluation of the source term for fission-product release under accident conditions. Qualitatively, the influence of the stoichiometry on the release of ¹³³Xe, ¹³¹I, and ¹³²Te has been established. | |
