Effect of catalytic metals on tritium release from ceramic breeder materials

Tritium release from lithium silicate pebbles produced from lithium hydroxide

“…2 and 3 indicate that the addition of hydrogen to the sweep gas has little effect on the enhancement of tritium release. In our previous work, tritium release experiments on Li 4 SiO 4 pebbles fabricated by an old different process were studied with a 0.1% H 2 /N 2 sweep gas by the same experimental method described in this paper [3]. In terms of the Li 4 SiO 4 pebbles, the tri- Fig.…”

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].…”

Out-of-pile tritium release study on Li4SiO4 pebbles from TRINPC-I experiments

“…Since there are not enough out-of-pile tritium release data on the specimens used in this research, referring to other references is preferred for explaining the two temperature peaks of tritium gas. Munakata et al [7,8] conducted similar out-of-pile tritium release experiments on Li 4 SiO 4 pebbles with 0.1% H 2 /N 2 sweep gas. The heating rate of the breeder was 5°C/min.…”
