The role of temperature, deuterium pressure and residual gases in deuterium retention and outgassing of lithium deuterium co-deposits

Liquid lithium (Li) divertor concepts offer a promising solution for D the divertor in future fusion reactors. However, D lithium’s strong affinity for hydrogen isotopes raises concerns regarding tritium D inventory requirements and tritium breeding ratio. In particular, tritium-lithium co-deposits studies are critical, as co-deposits may D contribute significantly to tritium retention in inaccessible areas, complicating D tritium recovery......
