REGULATORY APPROACH ON REGULATORY APPROACH ON DECOMMISSIONING OF NUCLEAR INSTALLATIONS DECOMMISSIONING OF NUCLEAR INSTALLATIONS APPLICABLE REGULATIONS TO THE DECOMMISSIONING STAGE: � Licencing of Relevant Nuclear Installations � Basic Standard for Radiological Safety � Decommissioning of Nuclear Power Plants � Radioactive Waste Management � Estimation of the radioactive material inventory � Volume,materials(metals,wood,textil,plastic) � Old facilities 8

NATIONAL ASPECTS OF THE D&D D&D ACTIVITIES ACTIVITIES NATIONAL ASPECTS OF THE According to chapter I, Art. 2.e of the National Law Nº 24804 ruling nuclear activities CNEA “ Is responsible for determining the procedure for decommissioning Nuclear Power Plants and any other relevant radioactive facilities.” The implementation the Nuclear Law, states that CNEA is responsible for decommissioning of all relevant radioactive facilities in the country, at end of life. Consequently in May 2000 CNEA created a D&D branch within its Unit of Technology. 10

Real Situation According with this Scenario Many structural components and old facilities were or must be removed or treated. The main activities are focused in: Preliminary planning and radiological characterization f or research reactors RA1,RA3 and RA6: A preliminary planning was given to the Regulatory Body during this year. Characterize structural components ,valves, flanges, etc. Evaluate the decontamination and the treatment of the liquids generated. The final aim must be: reuse, declassified or waste. 11

Works in progress progress: : Works in � Segregation of waste � Volume Evaluation � Characterization � Decontamination: by using agressive solutions in ultrasonic bath and/or abrasive treatment. � Evaluation of cutting technics 12
