Analysis of Tritium Transport Mechanisms at the Surface of Lithium Ceramics

An analysis was made of the surface fluxes of hydrogen species in order to determine the activation energies which affect the bulk and surface inventories in a lithium ceramic. It was found that in the absence of protium, Sievert Law is obeyed and the concentration depends on However, in the presence of protium, the concentration depends on P_HT. The bulk and surface concentrations were found to depend on a combination of all four surface energies in the activation energy of solution and the heat of adsorption.
