ANALYTICAL APPROXIMATION FORMULAE FOR HYDROGEN DIFFUSION IN A METAL SLAB
This report treats hydrogen diffusion in the first wall of a fusion machine (INTOR, reactor, etc.), taking the thermal load into account. Analytical approximation formulae are given for the concentration and flux density of hydrogen diffusing through a plane metal slab. The re-emission flux, particularly during the dwell time(s) of machine operation, is also described with analytical formulae. The analytical formulae are compared with numerical calculations for steel as first wall material.
