Zusammenfassung:PROBLEM TO BE SOLVED: To provide a new energy saving three-chamber type electrolytic cell for tritium recovery that can improve the tritium removal ratio by an electrolytic method, and a tritium recovery system using the electrolytic cell.SOLUTION: A three-chamber type electrolytic cell for tritium recovery comprises an anode chamber in which an anode is placed, an intermediate chamber that is separated from the anode chamber by an anode-side electrolyte layer film and into which water containing tritium and a hydride is poured, and a cathode chamber in which a cathode is placed and which is separated from the intermediate chamber by a cathode-side electrolyte layer film. Bond energy between hydrogen and other elements of the hydride is smaller than O-H bond energy between oxygen (O) and hydrogen (H) in water. Light energy containing a wavelength component longer than a wavelength capable of imparting energy exceeding the O-H bond energy to decompose the bond and shorter than a wavelength capable of decomposing the bond of the hydride is irradiated to the intermediate chamber. In a tritium recovery system, the three-chamber type electrolytic cells are connected in a multistage manner. 【課題】電解法でのトリチウム除去率の向上を図れる新たな省エネルギー型のトリチウム回収用三室型電解槽およびこれを用いたトリチウム回収システムを提供する。【解決手段】陽極の置かれる陽極室と、該陽極室と陽極側電解質層膜で隔てられトリチウム及び水素化物を含んだ水が注入される中間室と、該中間室と陰極側電解質層膜で隔てられ陰極の置かれる陰極室と、を備えるトリチウム回収用三室型電解槽であって、前記水素化物の水素と他の元素との結合エネルギーが、水における酸素(O)と水素(H)とのO−H結合エネルギーよりも小さく、前記中間室に前記O−H結合エネルギーを超えるエネルギーを与えて結合を分解させ得る波長よりも長く前記水素化物の結合を分解させ得る波長よりも短い波長成分を含む光エネルギーが照射されるトリチウム回収用三室型電解槽及びこれらを多段接続したトリチウム回収システム。【選択図】図1
