THREE-CHAMBER TYPE ELECTROLYTIC CELL FOR TRITIUM RECOVERY AND TRITIUM RECOVERY SYSTEM

摘要

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.;COPYRIGHT: (C)2016,JPO&INPIT
