Objective
CHARACTERISTICS OF POLYMERS ARE CONVENIENT FOR PRODUCING COATINGS WITH GOOD PROPERTIES OF DURABILITY AND MECHANICAL RESISTANCE. THE STUDY CONCERNS THE DEVELOPMENT OF THICK COATINGS WITH POLYMERS ON METALLIC PIECES OR ON CONCRETE. INDEED, AN IMPORTANT THICKNESS ALLOWS THE LOWERING OF DIFFUSION OF RADIONUCLIDES AND PROTECTS DIRECTLY THE SURFACE OF CONTAMINATED PIECES WITHOUT COMPLEMENTARY PROCESS OF CUTTING OR EMBEDDING. NEW POSSIBILITIES ARE THEN FOUND IN THE FIELD OF HANDLING, TRANSPORT AND STORAGE OF LARGE SIZE WASTES ISSUING FROM DISMANTLING OF NUCLEAR PLANTS.
]THE AIM OF THIS PROGRAMME IS TO DEMONSTRATE THE POSSIBILITY OF APPLYING THIS TYPE OF COATING ON REAL CONTAMINATED PIECES FROM DISMANTLING.ATTENTION WILL BE GIVEN TO CONTROLS OF REPRESENTATIVE RADIONUCLIDES DIFFUSION, MECHANICAL AND TEMPERATURE RESISTANCE.
The aim of the research work was the development of new techniques to control contamination and contain radioactive waste using polyurethane paints.
The following main stages have been carried out:
determination of the polyurethane paint most suited to this application using water diffusion tests and the diffusion of radioactive elements;
choice of the spraying technique suitable for use in an ionising environment;
initial application of the technique at a site being dismantled.
B.1. FEASIBILITY STUDY OF A PROCEDURE SUITABLE FOR COATING LARGE COMPONENTS.
B.2. MECHANICAL, THERMAL AND RADIO-DIFFUSION OPTIMIZATION OF POLYMER COATING WITH PARTICULAR RESPECT TO GEOMETRY,SURFACE CONDITIONS AND NATURE (METAL, CONCRETE...) OF THE COMPONENTS.
B.3. STUDY OF MOBILE PROJECTION APPARATUS SUITABLE TO BE ADAPTED FOR APPLICATION IN THE NUCLEAR AREA AND ABLE FOR PROJECTION THICK COATINGS ON LARGE COMPONENTS AS GIVEN IN B.2.
B.4. PREPARATION OF A PROJECTION AREA AT PILOT PLANT SCALE TO DEMONSTRATE THE FEASIBILITY OF THE PROCEDURE ON COMPONENTS > 1M AND ON LARGE DIMENSION LOW LEVELS WASTE.
B.5. APPLICATION OF THE PROCEDURE WITHIN THE FRAME OF A DISMANTLING PROJECT IN FRANCE OR ANOTHER EC COUNTRY.
