Annihilation kinetics of irradiation defects in promising tritium breeding pebbles
Nuclear Materials and Energy, 2021 Lithium-based tritium breeding materials will be adopted to produce tritium in the D-T fusion reactor. Li2TiO3 and Li4SiO4 pebbles have been proposed as candidates in water-cooled ceramic breeder blanket (WCCB) and helium-cooled ceramic breeder blanket ...

Probabilistic risk assessment model for released tritium into the environment for CFETR
Nuclear Fusion, 2022 The China Fusion Engineering Test Reactor (CFETR) is the next facility in the Chinese roadmap to realize sustainable-clean fusion energy. Because of the large tritium inventory of the CFETR, safety analyses are necessary.

Trap and release of tritium formed in silica and alumina. [PDF]
Journal of Nuclear Science and Technology, 1981 The ability of trapping of tritium by silica and alumina which were preliminarily doped with Li and irradiated with neutrons, and the removal of tritium from these materials by ethylene were investigated. Tritium formed in almina was not liberated by the elevation of temperature to 350°C.

Comparison of release behavior of water vapor and tritiated water vapor from natural soil by heating
Nuclear Materials and Energy, 2018 In a water-cooled nuclear fusion power plant, a large amount of tritiated water will be handled. Assuming severe accidents including the release of tritiated water to the surrounding environment, it is important to understand the tritium behavior in ...

Tritium deposition in pine trees and soil from atmospheric releases of molecular tritium [PDF]
Environmental Science & Technology, 1984 Much of the tritium found in soil and leaf litter near a chemical separations facility is incorporated into soil organic matter in a stable non-exchangeable form. Formation of this ''bound'' tritium seems to result from the uptake of molecular tritium (HT) by living pine needles.

Tritium extraction in aluminum metal by heating method without melting
Nuclear Engineering and Technology, 2022 Tritium was extracted from tritium-contaminated aluminum samples by heating it in a high-temperature furnace at 200, 300, or 400 °C for 15 h. The extracted tritium was analyzed by using a liquid scintillation counter (LSC); the sample thicknesses were 0 ...
