[en] The release of tritium from tritiated yttrium, yttrium-nobium (3:7) alloy, and yttrium-thorium (4:1) alloy in an Ar flow was examined preliminarily in the temperature range of 973 to 1173 K. At 1173 K, tritium was released with yields of 10to 40% after a 6 h heating period. The data was consistent with a model based on gas-phase transport of tritium with no resistance to mass transfer coming from either the solid or interfacial regions. Therefore, the release rate can be determined from equilibrium considerations only. (orig.)
