In case of nuclear fusion reactor, the most of the fuel injected is discharged without the reaction. Therefore, the system that can reuse the fuel discharged is necessary. And, at blanket located around the core plasma, tritium is made by the reaction of neutron and lithium, is recovered and is used as fuel. In the research and development of these fueling systems, the collaboration with US having the facility that can handle the large amount of tritium has become important. In this section, the results of the US-Japan collaboration related to the development of fueling system technology will be presented.
