Journal ArticleDOI
Helium and hydrogen release measurements on various alloys irradiated in SINQ
TL;DR: In this paper, three irradiations have been performed in the Swiss Spallation Neutron Source (SINQ) to establish a materials database for mixed proton and neutron fluxes for future spallation neutron and other accelerator sources.
Journal ArticleDOI
Tritium retention and migration in beryllium
TL;DR: In this article, a coordinated experimental program performed to characterize the hydrogen isotope retention and release in beryllium was presented, and the results showed that the retention was seen to initially decrease with increasing exposure temperature, but reached a local maximum at 770 K.
Journal ArticleDOI
Recombination of deuterium atoms on the surface of molten Li–LiD
TL;DR: In this paper, the rate constant k r describing surface recombination of deuterium atoms into molecules, were made for various molten mixtures of Li-LiD using a thermal desorption technique.
Journal ArticleDOI
Tritium inventory and permeation in the ITER beryllium
Rion A. Causey,K.L. Wilson +1 more
TL;DR: In this paper, the authors present the results of modeling the tritium inventory in the beryllium components of ITER using Diffuse computer code, which predicts that the inventory is a strong function of both the assumed surface recombination rate constant and the trap density.
Journal ArticleDOI
A continuum-scale model of hydrogen precipitate growth in tungsten plasma-facing materials
TL;DR: In this article, a model of 3He gas bubbles in tungsten tritides was developed to simulate the growth of near-surface hydrogen precipitates during high-flux plasma exposure, strongly affecting migration and trapping in the material.
