Hydrogen permeability of the first wall of a thermonuclear reactor

Assessment of database for interaction of tritium with ITER plasma facing materials

“…Surface defects may catalyze recornbination of H. Hydrogen atoms may also be ejected by incident particles. (Sharapov et al 1986) Aitchison et a1 (1993) found that exposure to 0.2 Torr of oxygen reduced deuterium permeation through initially clean 403 SS by two orders of magnitude.…”
