Abstract
Analysis of experimental data and modeling of processes of hydrogen isotope retention, diffusion and release from beryllium irradiated in two fission reactors were carried out. The activation energies of hydrogen release for five TDS peaks were calculated according to the mechanism of second order d esorption. An attempt was made to describe high-temperature peak by bulk di ffusion from beryllium with surface oxide layer. (C) 1998 Elsevier Science B.V. All rights reserved.
