The geochemistry of tritium

Eos, Transactions American Geophysical Union, 1958
The tritium concentration has been determined in precipitation, ocean waters, and ground waters. Although the steady‐state tritium ‘cycle’ has been disturbed by thermonuclear testing, enough analyses of pre‐test water have been made to conclude that: (1) the North Atlantic surface water had a natural mean T:H = 1.0 × 10−18 which doubled in 1954 because

Study on Tritium Production and Effluent Source Term for HPR1000 [PDF]

E3S Web of Conferences
During the operation of nuclear power plants, fuel fission and activation of boron and lithium in reactor coolant will produce a certain amount of tritium, which is difficult to be removed by conventional waste treatment system, and will cause certain ...

Tritium-Lean Fusion Power Plants with Asymmetric Deuterium-Tritium Transport and Pumping [PDF]

arXiv
Asymmetries in deuterium-tritium (D-T) particle transport and divertor pumping speeds are shown to enhance tritium self-sufficiency in fusion power plants. Using a diffusive particle transport model that links the plasma core, separatrix, and divertor regions, it is shown that reducing tritium transport while increasing deuterium transport improves ...

Evaluation of tritium release curve in primary coolant of research reactors

Physical Sciences and Technology, 2018
Increase of tritium concentration in the primary coolant for the research and testing reactors during reactor operation had been reported. To clarify the tritium sources, a curve of the tritium release rate into the primary coolant for the JMTR and the ...

Preliminary assessment of tritium permeation and retention in the European Water Cooled Lithium Lead Test Blanket Module with TESSIM-X

Nuclear Materials and Energy, 2022
Tritium self-sufficiency is a key requirement for future fusion power plants. Therefore, it will be necessary to minimize tritium losses to the surrounding systems, such as the tritium breeding modules, plasma-facing components, cooling system, etc ...

Status of the Project 8 Phase II [PDF]

arXiv, 2017
The Project 8 collaboration aims to measure the absolute neutrino mass scale using cyclotron radiation emission spectroscopy on the beta decay of tritium. The second phase of the project will measure a continuous spectrum of molecular tritium beta decays and extract the tritium endpoint value with an eV or sub-eV scale precision.

Detector Development for a Sterile Neutrino Search with the KATRIN Experiment [PDF]

arXiv, 2018
The KATRIN (Karlsruhe Tritium Neutrino) experiment investigates the energetic endpoint of the tritium $\beta$-decay spectrum to determine the effective mass of the electron anti-neutrino with a precision of $200\,\mathrm{meV}$ ($90\,\%$ C.L.) after an effective data taking time of three years.
