For investigating the tritium behavior in molten-salt blanket, a new neutron irradiation experiment has started with FLiNaK (LiF-NaF-KF) and AmBe neutron source. Releasing tritium from FLiNaK by running He gas, TF and T₂ are recovered separately by water bubbling. The results of recovered tritium measurement using a liquid scintillation counter will be reported.
