Japanese Patent JP6391633

B2

PROBLEM TO BE SOLVED: To provide a separation method and a device of high dose waste capable of reliably separating waste sand and granular waste resin as high dose waste which are generated in processing of supernatant water in a used fuel reservoir at a low cost.SOLUTION: The separation device of high dose waste includes: a separation tank 1 into which high dose waste containing waste sand and granular waste resin; a water flow generating chamber 6 that generates water flow mixed with air, which is disposed at the bottom part of the separation tank 1 via a first a porous plate 7; a header 9 which is connected to the bottom part of the water flow generating chamber 6 via a second porous plate 10; an air injection pipe 12 connected to the bottom part of the water flow generating chamber 6; and a water pipe 13 connected to the header 9. A granular waste resin take-out port 4 for taking out granular anion waste resin and granular cation waste resin in this order from the separation tank constituting granular waste resin is provided in an upper part of the separation tank 1. In a lower part of the separation tank 1, a waste sand take-out port 3 is provided for taking out the waste sand from the separation tank 1. The size of the opening of the first porous plate 7 is smaller than the size of the opening of the second porous plate 10.SELECTED DRAWING: Figure 1
