PURPOSE:To separate and concentrate a hydrogen isotope with little power consumption by electrochemically transferring oxygen from heavy isotope water, such as tritium water to light isotope hydrogen. CONSTITUTION:A hydrogen isotope raw material (for example, tritium water) is supplied to a water-hydrogen isotope exchange reactor 11 where it is concentrated, and the concentrated water is introduced from a concentrated water outlet 13 to a water-hydrogen converter 17 (for example, that using an oxygen ion conductive solid electrolyte cell 18) where hydrogen is formed. Part of the hydrogen thus formed is taken off as a product and the other part is returned from a hydrogen inlet 14 to the exchange reactor 11 where the hydrogen transfers its tritium to water and the hydrogen thus formed is delivered from a hydrogen outlet 15 to the convertor 17. This causes a hydrogen isotope in tritium water to be continuously separated. To the converter 17, are fed the concentrated water of heavy isotope on one side of the cell 18 and the concentrated hydrogen of light isotope on the other side, permitting the exchange of water to hydrogen and vice versa to be spontaneously made. |
