| Outline of Final Research Achievements |
It has been found that hydrogen recycling from molten lithium is reduced, relative to that from solid lithium. This is believed to be because of Einstein-Stokes diffusion of lithium hydride (LiH) particles precipitated in the implatation range. However, if the liquid is stirred, the reduction in hydrogen recycling is significantly enhanced, presumably because of the disaturation effect. This means that liquid metal PFC concepts need to incorporate some forced convection effect to maintain reduced recycling in the edge region of a magnetic fusion device.
