Abstract
When neutron-irradiated Li(1 wt%)-Al alloys were heated under vacuum at temperatures above 770 K, more than 95% of tritium was extracted in the gas phase within 1 h. The predominant species of extracted tritium were HT and HTO, although the distribution of both species varied depending upon the extraction temperature. The specific activity of the HT fraction was found to change within wide limits also depending upon the extraction temperature. The phenomenon was attributed to the difference in the release behaviour between tritium produced by the6Li(n, α) T reaction and protium contained as impurity in the alloy.
