The steady state plasma-driven permeation flux has been found to be strongly affected by the variation in upstream surface morphology resulted from plasma bombardment. The activation energy of permeability for gas-driven permeation has been estimated to be ∼ 0.5 eV, which is close to the result of plasma-driven permeation. Gas-driven permeation can occur in the opposite direction of plasma-driven permeation, which then results in an increase in first wall recycling.}, title = {Bi-Directional Hydrogen Permeation through F82H under DEMO-Relevant Conditions}, volume = {8}, year = {2013} }
