Activation analysis of tritium breeder materials in the FDS-II fusion power reactor

Lithium lead (Li17Pb83) is presently considered as a primary candidate tritium breeder for fusion power reactors because of its attractive properties. Its induced radioactivity by D–T fusion neutrons was calculated with the fusion power reactor (FDS-II) as the reference reactor. The results were compared with the activation levels of other tritium breeders, such as Li4SiO4, Li2TiO3, Li2O, Li, etc., under the same irradiation conditions. Furthermore, the dominant nuclides to dose rate of Li17Pb83 and the effects of irradiation time on the activation characteristics of Li17Pb83 were analyzed.
