Evidence for tritium persistence as organically bound forms in river sediments since the past nuclear weapon tests

open access: yesScientific Reports, 2019
Tritium of artificial origin was initially introduced to the environment from the global atmospheric fallout after nuclear weapons tests. Its level was increased in rainwaters by a factor 1000 during peak emissions in 1963 within the whole northern ...

ViMA -- the spinning rotor gauge to measure the viscosity of tritium between 77 and 300 K [PDF]

open access: yesarXiv, 2022
Experimental values for the viscosity of the radioactive hydrogen isotope tritium (T$_2$) are currently unavailable in literature. The value of this material property over a wide temperature range is of interest for applications in the field of fusion, neutrino physics, as well as to test ab initio calculations.

Calibration of a transient transport model to tritium data in streams and simulation of groundwater ages in the western Lake Taupo catchment, New Zealand [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Here we present a general approach of calibrating transient transport models to tritium concentrations in river waters developed for the MT3DMS/MODFLOW model of the western Lake Taupo catchment, New Zealand.

Long life neutron generator target using deuterium pass-through structure [PDF]

open access: yes, 1974
Target structure permits all deuterons, except the one-in-a-million that interacts with tritium atom to produce a neutron, to pass completely through target structure and be returned to vacuum system.

Sensitivity of Next-Generation Tritium Beta-Decay Experiments for keV-Scale Sterile Neutrinos

open access: yes, 2014
We investigate the sensitivity of tritium $\beta$-decay experiments for keV-scale sterile neutrinos. Relic sterile neutrinos in the keV mass range can contribute both to the cold and warm dark matter content of the universe.

Modelling solute transport in soil columns using advective-dispersive equations with fractional spatial derivatives [PDF]

open access: yes, 2010
Solute transport in soils is commonly simulated with the advective–dispersive equation, or ADE. It has been reported that this model cannot take into account several important features of solute movement through soil.

Tritium Diffusion Pathways in γ-LiAlO2 Pellets Used in TPBAR: A First-Principles Density Functional Theory Investigation

open access: yes, 2018
With superior thermophysical and thermochemical properties, γ-LiAlO2 has high compatibility with other blanket materials and is used in the form of an annular pellet in tritium-producing burnable absorber rods (TPBARs) to produce tritium by thermal ...

Quantitative estimation of tritium amount in surface layer and bulk of tungsten sample using BIXS

open access: yesNuclear Analysis, 2023
Estimation of both the surface tritium and tritium in bulk in key materials of fusion reactors is of great importance for tritium safety and the management of tritium-contaminated material.

Calibration of Tritium Microcalorimeter and Calorimetric Verification of Tritium Samples

open access: yesJournal of Isotopes, 2023
Radioactive isotope decay gives off heat, which is an important basis for calculating the activity of radioactive isotope. In order to measure the heat emitted by tritium decay, the detection limit test, working curve calibration and tritium sample ...

Overview of the JET preparation for deuterium-tritium operation with the ITER like-wall [PDF]

open access: yes, 2019
For the past several years, the JET scientific programme (Pamela et al 2007 Fusion Eng. Des.82 590) has been engaged in a multi-campaign effort, including experiments in D, H and T, leading up to 2020 and the first experiments with 50%/50% D–T mixtures ...
