Adsorption characteristics of tritium in lithium vacancy for Li4SiO4: A density functional theory study

open access: yesNuclear Engineering and Technology
Lithium orthosilicate (Li4SiO4) is a promising breeder material with its high lithium density and low tritium retention for fusion reactor blanket. After neutron irradiation, Li4SiO4 not only produces tritium but also forms lithium vacancy defects, which

Tissue distribution, excretion and effects on genotoxicity of tritium following oral administration to rats

open access: yesNuclear Engineering and Technology, 2019
Tritium is an important nuclide that must be monitored for radiation safety management. In this study, HTO was orally administered to rats at the level of 37 kBq (1 μCi) or 370 kBq (10 μCi) to examine tissue distribution and excretion levels.
