Build-Up of Tritium in a Liquid-Lithium Breeding Blanket for an Inertial-Confinement-Fusion Chamber

摘要

The build-up of tritium in a liquid lithium breeding blanket for an ICF chamber has been examined. The break-even time is found to decrease both the increasing tritium breeding ratio and increasing values of alpha , the fraction of unburned tritium absorbed in lithium. The break-even inventory also decreased with increasing breeding ratio but increases with increasing values alpha . For a molten-salt extraction process, the steady-state tritium inventory in lithium is inversely proportional to lithium flow rate through the extraction system. The lithium flow rate through the tritium extraction system required to maintain a given tritium concentration increases with increasing values of alpha . (ERA citation 07:013545)
