FIELD: nuclear engineering.
SUBSTANCE: proposed method that can be used for decontaminating radionuclide-contaminated metal surfaces of various nuclear power installations, manufacturing and other pieces of equipment, including those having complex configuration and subject to disposal and burial, involves their scanning by contact-arc discharges from current supply having flat current-voltage characteristic of at least 280 A/V at voltage of 7 - 4 V across working electrodes; granules of contaminated metal brought out of decontamination zone are sized to minimum 0.05 mm.
EFFECT: enhanced productivity and personnel safety.
