Tritium Diffusion in Fusion Reactor Blankets

The steady-state diffusion of tritium in a fusion reactor blanket has been evaluated using the Los Alamos Scientific Laboratory Theta-Pinch reactor as a reference system. The purpose was to calculate the equilibrium tritium transport rate, approximate time to reach equilibrium, and tritium inventory in various regions of the reactor blanket as a function of selected blanket parameters. Values for these quantities have been tabulated for blanket conditions that appear reasonable for the reference system.
