The hydrogen isotope transport through the first wall between plasma and first wall coolant has been investigated. The time dependence of hydrogen isotope permeation through the first wall from plasma into water coolant has been calculated. The hydrogen isotope inventory (both mobile and trapped hydrogen isotopes) in the first wall has been evaluated. The influence of temperature gradient, surface conditions, isotopic effect and trapping in the ion- and neutron-induced defects on the hydrogen isotope permeation and inventory has been considered.
