摘要

Bulk hydrogen retention and hydrogen diffusion in graphite and carbon materials have been studied to estimate hydrogen recycling and tritium inventory in a fusion reactor environment. Hydrogen may permeate into a filler grain in the form of a hydrogen molecule. diffuse through crystallite boundaries and finally be trapped as hydrogen atoms at the edge surface of a crystallite. In the estimation of hydrogen transport, the activation energy of hydrogen diffusion can be determined from absorption experiments. and the activation energy of detrapping can be obtained from desorption experiments. The activation energies of hydrogen trapping are 2.6eV in ordinary graphite and 4.4eV for irradiated or mechanically milled graphite samples. [References: 30]
