英文摘要For the operation of D-T fusion reactor, tritium breeding materials will be adopted to produce tritium. Li2TiO3-Li4SiO4 biphasic breeders are considered as promising breeding materials due to combining the ad-vantages of Li2TiO3 and Li4SiO4. The annihilation kinetics of defects induced by gamma-ray irradiation in xLi(2)TiO(3)-(1x) Li4SiO4 (molar ratio: x = 0.25,0.5,0.75) have been investigated. ESR and Easyspin simulation were employed to elucidate the annihilation processes of the irradiation defects. The defects of E'-center and O--center were introduced by irradiation. The amount of defects decreased as the molar ratio of Li2TiO3/Li4SiO4 increased. It was indicated that the irradiation stability of Li2TiO3 was better than that of Li4SiO4. According to Easyspin simulation, the defect density of E'-center and O--center was obtained respectively and the amount of defects decreased as the annealing temperature increased. The activation energy and kinetics equation of E'-center and O--center in xLi(2)TiO(3)-(1-x) Li4SiO4 (x = 0.25,0.5,0.75) were obtained. Based on annihilation kinetics, the correlation between annihilation of irradiation defects and tritium release was given.
