Tritium implantation in the accelerator production of tritium device [PDF]

open access: yes, 1997
We briefly describe the methods we have developed to compute the magnitude and spatial distribution of born and implanted tritons and protons in the Accelerator Production of Tritium (AFT) device. The methods are verified against experimental measurements and then used to predict that 16% of the tritium is implanted in the walls of the APT distribution

Tritium permeability measurement in hydrogen-tritium system

open access: yesFusion Engineering and Design, 2018
Abstract Understanding of thermodynamic equilibria of multi-components hydrogen isotopes is required to accurately measure tritium permeability at the expected low tritium partial pressure and non-negligible high hydrogen partial pressure in a fusion blanket system.

Epigenetic and genotoxic effects of tritium in marine mussels: Comparing waterborne and metal-associated forms

open access: yes
Tritium (3H), an isotope of hydrogen, is a by-product of the nuclear industry. Decommissioning and normal operations of nuclear facilities can generate tritiated stainless-steel particles (T-SSPs) that could be unintentionally released into the ...
