Description

Chemical behaviour of tritium produced by the 6Li(n,α)T reaction in Li7Pb2 has been investigated with emphasis on the thermal release processes. When the neutron-irradiated Li7Pb2 was heated under vacuum, the tritium was released mainly in the form of HT. The HT release rate was found to obey diffusion-controlled kinetics. The diffusion coefficient of tritium in solid Li7Pb2 at temperatures ranging from 560 to 700 K was determined to be D=2.1x10-3 exp (-45.1/RT) cm2s-1. The tritium release behaviour of Li7Pb2 was compared with that of Li45Pb55 in which a distinct phase effect was observed in the HT release processes. (orig.)
