Experimental Determination of Hydrogen Isotope Transport Parameters in Vanadium.

Deuterium permeation through vanadium membranes in a wide range of pressures and the temperature range ~250-550 °C was experimentally investigated. Measurements on the same material were carried out in three laboratories with different features for an extended characterization and for cross-check validation. A unified equation for deuterium permeability in pure vanadium (99%) was provided as Φ=1.
