In order to enhance safety of fusion reactor, JAEA investigates effective tritium removal system in case of incidental tritium release in the building. Recently, we paid attention to the bacteria, which had an ability of hydrogen oxidation at room temperature, and a new effective detritiation system using the bacteria has been studied under the collaboration with Ibaraki University, instead of catalytic oxidation reactor of rare metal.
