摘要
The present invention is U 3 O 8 of spent nuclear fuelPressing and molding the powder to prepare U 3 O 8 pellets; Heating the U 3 O 8 pellets at a temperature of 550 to 700° C. under a hydrogen atmosphere to prepare UO 2 pellets; It relates to a process for preparing a porous UO 2 pellets containing; and to prepare a porous UO 2 pellets by heat-treating the UO 2 pellets. Not porous UO 2 pellets according to the invention CsTcO 4 is generated, it is not a required further separation for the solidification and disposal of CsTcO 4, it may be cesium to remove 99% or more, to volatilize a cesium compound in the fly ash filter Efficient disposal is possible because of selective collection.
