Light water reactor spent fuel reprocessing method and apparatus

摘要

The present invention relates to a light water reactor spent fuel reprocessing method and apparatus for treating a light water reactor spent fuel to obtain fast reactor fuel without adding plutonium from the outside, and relates to a light water reactor spent fuel (1) as an elution anode (2 ) As the elution cathode (3) and the elution molten salt (4) to which the uranium oxide supply source is added, a voltage is applied to extract the uranium oxide (6) from the light water reactor spent fuel (1). (4) The uranium oxide elution part (8) for carrying out the uranium oxide elution step for elution into the elution cathode (3) and the elution anode (2) residue (10) is reduced to the reduction cathode ( 11) is immersed in a reducing molten salt (13) to which an oxygen supply source is added together with the reducing anode (12), and a voltage is applied between the reducing anode (12) and the cathode (11) to form a residue (10). ) Is reduced to obtain an alloy (16) Provided with a door.
