Abstract

Metal–hydrogen systems are of great basic and technological interest. In fusion reactors, absorption and desorption of hydrogen isotopes by the first wall and blanket structure are open problems. Hydrogen accumulation at adiation-induced defects in steel may have serious detrimental effects on the structure of steel. In this work, we present the results of a numerical code realized for simulating the hydrogen desorption processes and point out the advantage related with the numerical approaches to the problem. Indeed, as opposed to the analytical procedures which need approximations to avoid mathematical complications to include traps coverage, the numerical approaches work without any approximation. 2006 Elsevier B.V.
