Problems related to tritium in the fuel cycle of a D-3He fusion reactor are discussed. About 15 g/day of tritium is estimated to be exhausted from a 1-GW(electric) D-3He reactor. The cumulative amount of tritium in storage reaches ∼80 kg after 30 yr of operation if all the tritium exhausted from the plasma is confined.
