A tritium removal device for a lithium loop contains a neutron source (1) for colliding protons on a lithium flow, thereby generating neutrons, a lithium tank (11) for the lithium passing through this neutron source (1) to flow thereto through a flow passage (9), thereby temporarily accumulating it therein, and a lithium pump (17) for circulating and supplying the lithium of this lithium tank (11) to the neutron source (1) through a supply-side flow passage (9′). The lithium tank (11) and the lithium pump (17), into which hydrogen gas containing tritium therein can be easily collected, are enclosed within a hermetically sealed container (7) including an inactive gas therein, so that even if the hydrogen gas including the tritium therein is leaked into the hermetically sealed container (7), it is removed by a hydrogen isotope removal filter.
A tritium removal device comprising a lithium loop, the lithium loop comprising a neutron source for generating neutrons through the collision of proton rays with flowing lithium, a lithium tank for storing lithium therein, a first flow passage for transporting lithium from the neutron source to the lithium tank, a second flow passage, a lithium pump for transporting lithium from the lithium tank to the neutron source through the second flow passage and a hermetically sealed container enclosing the lithium tank and lithium pump therein, and the tritium removal device further comprising an argon supply tank for supplying argon gas to the hermetically sealed container, a used argon tank for receiving argon gas from the hermetically sealed container and a hydrogen isotope removal filter for removing tritium-containing hydrogen gas from the argon gas being received in the used argon tank.
