Abstract
A brief review is presented on the hydrogen diffusion in beryllium and graphite materials. It is shown that the hydrogen diffusion coefficie nts obtained at temperatures below 900 K should be used for evaluation of hydrogen inventory in graphite material. The effect of different p arameters on hydrogen inventory is demonstrated by means of numerical calculations. The obtained value for hydrogen inventory in ''virgin'' RGT graphite is 0.1 g per metric ton material at a temperature of 850 K.
