FIELD: decontaminating methods.
SUBSTANCE: proposed method for decontaminating nuclear reactor circuit includes treatment of internal surfaces with oxalic acid solution at the same time cleaning decontaminating solution from corrosion products dissolved on ion-exchange filters filled with anionite in oxalate form. Oxalate-form anionite filters are periodically reconditioned using nitric acid solution.
EFFECT: reduced amount of decontamination process wastes.
