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

NATIONAL ASPECTS OF THE NATIONAL ASPECTS OF THE D&D D&D ACTIVITIES ACTIVITIES

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.

11

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.

12

Works in Works in progress progress: :

Segregation of waste Volume Evaluation Characterization Decontamination: by using agressive solutions

in ultrasonic bath and/or abrasive treatment.

Evaluation of cutting technics
