Release behavior of bred tritium from LiAlO2

Existence states of deuterium irradiated into LiAlO2

“…However, it is important to clarify the differences between Li 2 O and other ternary oxides, since different tritium release behaviors have been observed for each Li-containing oxide [2,[17][18][19]. In this respect, we selected LiAlO 2 as a representative of the ternary Li-containing oxides, due to its particular hydrogen-releasing behavior [20][21][22][23].…”

Correlation between tritium release and thermal annealing of irradiation damage in neutron-irradiated Li2SiO3

“…It has reported that these irradiation defects could affect tritium recovery processes from the tritium breeding materials [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Therefore, for the establishment of the tritium recovery system, it is one of critical issues to understand the chemical behavior of tritium produced in the tritium breeding materials including its chemical states and release behavior.…”

“…Therefore, for the establishment of the tritium recovery system, it is one of critical issues to understand the chemical behavior of tritium produced in the tritium breeding materials including its chemical states and release behavior. Many researchers have investigated the production and annihilation of the irradiation defects such as F + -center, which is an oxygen vacancy occupied by one electron, in various tritium breeding materials, and their effects on tritium release behavior from the tritium breeding materials [1][2][3][7][8][9][10][11][12][13][14][15][16].…”

Estimation of tritium release behavior from solid breeder materials under the condition of ITER test blanket module

“…To analyze the effects of the surface reactions on tritium release behavior from solid breeder materials, tritium release experiments were carried out using a purge gas with different compositions (dry N 2 , N 2 with H 2 , N 2 with H 2 O) while applying the out-pile temperature programmed desorption techniques at the Japan Atomic Energy Research Institute (JAERI) [1][2][3][4].…”
