Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials. [PDF]

Small Methods
This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

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 ...

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABA_A Receptors That Modulate Dorsal Root Ganglia Neuron Excitability. [PDF]

Glia
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

Tritium Desorption Behavior and Microstructure Evolution of Beryllium Irradiated at Low Temperature Up to High Neutron Dose in BR2 Reactor

Journal of Nuclear Engineering, 2023
The present study investigated the release of tritium from beryllium irradiated at 323 K to a neutron fluence of 4.67 × 1026 m−2 (E > 1 MeV), corresponding up to 22,000 appm helium and 2000 appm tritium productions.

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 ...

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.

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.
