<P>PROBLEM TO BE SOLVED: To dispense with a maintenance of a spent fuel reprocessing apparatus by dispensing with a pipe transfer of solid contents in the reprocessing of spent fuel and preventing clogging of supernatant transfer means. <P>SOLUTION: The spent fuel reprocessing apparatus includes: a reaction container 12 to which spent fuel solution 11 is guided when reprocessing the spent fuel; a motor 21 for rotating the reaction container; oxalic acid input means 19 for adding oxalic acid to the interior of the reaction container 12; and supernatent transfer means 15 for extracting supernatent from a supernatent extraction port 15a opened into the reaction container 12 and transferring it with a pipe. When the oxalic acid is added to the spent fuel solution 11 and the reaction container 12 is rotated, the spent fuel solution 11 is separated, by a centrifugal force of the rotation, into an oxalic acid compound 16 as a solid content and the supernatent 14, and the separated supernatent 14 is recovered by the supernatent transfer means 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
