The annihilation behavior of irradiation defects introduced into neutron-irradiated Li2TiO3 and Li2ZrO3 was deduced from the T-release behavior. It was revealed that common characteristics of both samples were that the annihilation process of irradiation defects consisted of 2 first-order processes and that the E’-center could act as a T trapping site. Differences in the manner in which the E’-center annihilated were attributed to the mobility of M, as M4+ or M3+, etc.
