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

Nuclear 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

Aging Effects in Zr(Fe_0.5V_0.5)₂ Tritides

Crystals
We report an experimental study on the tritiding capabilities over a long period of the intermetallic compound Zr(Fe0.5V0.5)2. The study was carried out with the prospect of using the alloy as a chemical converter to reduce HTO. Two identical getter beds,

Studies of irradiated two-phase lithium ceramics Li4SiO4/Li2TiO3 by thermal desorption spectroscopy

Nuclear Materials and Energy
Two-phase ceramics Li2TiO3-Li4SiO4 are one of the potentially promising materials for creating a ceramic blanket for DEMO reactor. However, until now, a limited number of studies have been carried out on the release of tritium from this material under ...

Tritium content in water bodies in regions of peaceful nuclear explosions

Радиационная гигиена
Sites of peaceful nuclear explosions pose a potential radiation hazard to the territories of the Russian Federation, primarily due to the possible release of radioactivity from the explosion cavity into aquifers and onto the earth's surface.

Release of tritium from tritiated paints

, 1974
A study of the tritium losses from five tritiated phosphor paints showed that the losses from these paints were generally low. Samples of five different paints which were leach tested six times over a period of 11 months had losses ranging from 0.018 to 0.731% of the initial activity in the samples. Tritium evolved from a paint which had been cured for
