The tritium release behavior from Li $_{2}$ O sintered pellets is observed by isothemal heating tests. (1) For 81%TD,The rate determining process is controlled by Kohlrauch strecthed exponential form. Tritium trapped in irradiation defects released with recovering the defects by isothermal heating. (2) For 88%TD, tritium release behavior is controlled by Avrami law (exponent n=0.5). The rate determining process is the connected micro-pore migration process.

Disordering in Li $_{2}$ TiO $_{3}$ irradiated with high energy ions

Li $_{2}$ TiO $_{3}$ samples with high energy oxygen ions were examined by the use of Raman spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The Raman spectra of the irradiated samples do not show any evidence of destruction of Li $_{2}$ TiO $_{3}$ structure. On the other hand, the Bragg peak intensity of XRD is decreased with the increasing the ion fluence. Especially, the intensity of (002) supercell peak is drastically reduced after the irradiation to 1.2E+19 ions/m $^{2}$ . This result implies that partial site mixing between Li and Ti atoms is induced by the irradiation. The transition to such a disordering is observed also by SEM examination; the grain structure at surface layer is vanished after the irradiation.
