Abstract

A flowing-lithium vapor-box divertor for the compact breeder that couples heat exhaust to the fuel cycle. Coupled FESTIM/TMAP permeation-retention modelling ranks four liquid metals by tritium loss: lithium is optimal by three to six orders of magnitude over lithium-tin, lead-lithium, and tin, so the best power-handling surface is also the best inventory-control surface. Internal-platform concept, not a built system.
