Hulls waste volume-reduction treatment equipment

摘要

Apparatus for volume-reduction of hulls waste (20), i.e. zircaloy and fuel cladding tube residues (hulls) generated during chemical reprocessing of a light-wafer reactor spent fuel, has at least two rotary cylindrical bodies (2a, 2b) having a clearance between them and rotating in mutually opposite directions are provided and compressive reduction in the volume of the hulls waste is accomplished by loading it into the clearance between said rotary cylindrical bodies. The rotary cylindrical bodies may be arranged in order for at least the clearance to be positioned in water or means may be provided for feeding or spraying water downward into the clearance and thus dust due to the occurrence of zircaloy powder during compressive volume-reduction treatment is prevented from exploding.
