| Abstract: | Tritium release behavior from the pellets of γ-LiAlO2 was studiedby the thermodesorption method. According to the measured curves of different heating rates, the nominal diffusion activation energies of HT and HTO were calculated. Their values were （127±5）kJ·mol-1 and （253±50）kJ·mol-1 respectively. |
