Abstract
Tritium release behavior from neutron irradiated LiC 6 was investigated by heating up to 1000 °C. Released chemical species were found to be mainly molecular tritiated hydrogen (HT or T 2), accompanied by a small portion of CH 3T and HTO. Regarding tritium release kinetics, two peaks in tritium release were observed at 200–300 °C and 500–600 °C. The latter could be analyzed by diffusion-controlling kinetics, while the former by both diffusion-controlling and 1st order reaction kinetics. Judging from the values of diffusion coefficients and of activation energy, it is concluded that the tritium species behave with some interaction to lithium ions in LiC 6.
