FIELD: nuclear power.
SUBSTANCE: invention relates to production of fuel elements in nuclear reactors with uranium and MOX-fuel. Decontamination is performed by drawing a fuel element through a cartridge containing cleaning material, leaving no traces on surface of fuel element. After one drawing of fuel element used cartridge is removed from process. Decontamination can be both dry and wet. Decontaminating solution can be applied both at wiping material and applied to surface of fuel element. Device for implementation of present method comprises magazine for storage of new cartridges, system for feeding cartridges into decontamination zone, system for removing spent cartridges from decontamination zone, storage container, system for recycling spent cartridges, biological protection in case of operation with plutonium-containing fuel.
EFFECT: technical result is automatic decontamination of fuel element completely meeting requirements for operation with MOX-fuel.
