Dobrov, V. Kanyukova, S. Kurchatov, V. Likhanskii, O. Khoruzhii] A new model is developed for radiation sealing of intergrain boundaries under low-temperature irradiation conditions. The model agrees with the physical concepts concerning the mechanisms of athermal diffusion and radiation re-solution of gas bubbles. The model makes it possible to explain the experimentally observed sharp irradiation temperature dependence of gas release at low temperatures, even though the athermal radiation-stimulated transfer mechanisms predominate. The model was integrated into a mechanistic RTOP code and verified on experimental data, including Halden project data. 2 figures, 25 references.
