Studies of materials exhibiting low tritium permeation rates

Conference ·
OSTI ID:6025707
; ; ;
Tritium permeation is being measured through potential barriers, such as aluminum, copper, various oxides and glasses. The temperature range of the experiments is 300 to 500 K (25 to 200/sup 0/C) to compare such results to extrapolated high temperature data. A physical model is presented that accounts for the non-linear permeability seen at these low temperatures, where surfaces predominate.
