| Abstract Scope |
Tritium bred by the interaction of neutrons with lithium in molten salts is released through different mechanisms depending on the environment, forming various chemical species. The transport, permeation, and release dynamics vary between these pathways, and the presence of different species in the melt affects its redox state and corrosivity. Understanding the factors influencing tritium speciation and release mechanisms in molten salts is crucial for future fusion devices utilizing the Liquid Immersion Blanket (LIB) concept. New results from the LIBRA experiments, examining tritium breeding in molten FLiBe and ClLiF (LiF–LiCl eutectic), demonstrate the impact of cover or sparge gas composition on tritium release dynamics and speciation. Additionally, the composition of the gas swept outside the salt vessel is observed to influence the ability of permeated tritium to desorb from the walls, while also determining its chemical form. |
