Objective
THE CONTAMINATION OF CONCRETE IN NUCLEAR INSTALLATIONS IS MAINLY LOCATED IN THE VICINITY OF THE EXPOSED SURFACE, TO A DEPTH GENERALLY ESTIMATED AT A FEW MILLIMETERS. THEREFORE, DURING THE DECOMMISSIONING OF THESE INSTALLATIONS, TECHNIQUES ARE PREFERRED WHICH ARE CAPABLE OF REMOVING CONCRETE BY SUCCESSIVE THIN LAYERS SO AS TO MINIMISE THE QUANTITY OF RADIOACTIVE WASTE GENERATED. ON THE OTHER HAND, THE MINIMISATION OF AEROSOL EMISSION, DANGEROUS TO WORKERS, CONSTITUTES A SECOND CRITERION OF CHOICE FOR DECOMMISSIONING TECHNIQUES.
CONTRARY TO TRADITIONAL MECHANICAL TECHNIQUES, ELECTROCOMBUSTION IS LIKELY TO RESPOND SIMULTANEOUSLY TO THE TWO PREVIOUS CRITERIA, CAUSING SUPERFICIAL MELTING AND WEAKENING OF THE CONCRETE BY VERY HIGH TEMPERATURES.
THE AIM OF THE PRESENT RESEARCH IS TO DETERMINE BY INACTIVE EXPERIMENTS ON THE EXISTING TEST BENCH :
- THE EFFICIENCY OF THE PLASMA BURNER AS REGARDS THE SHALLOW DESTRUCTION OF CONCRETE AT A TEMPERATURE WHICH MAY EXCEED 3000 CELSIUS DEGREES;
- THE APPROXIMATE LEVELS OF AEROSOL EMISSION AND NOX INVOLVED IN THIS OPERATION.
B1. OPTIMISATION OF THE PLASMA-AUGMENTED BURNER UNDER NON-RADIOACTIVE CONDITIONS AS A MEANS FOR REMOVING CONCRETE LAYERS, INCLUDING THE FOLLOWING PARAMETERS : CONCRETE STRUCTURE, GAS COMPOSITION, TEMPERATURE AND VELOCITY OF EXIT GAS.
B2. APPLICATION OF THE PLASMA BURNER TO TWO TYPES OF CONCRETE, ONE OF THEM IMPREGNATED WITH NON-RADIOACTIVE CESIUM CHLORIDE FOR SIMULATION OF THE CONTAMINATION.
B3. CONTINUOUS MEASUREMENTS OF AEROSOL AND NOX GAS QUANTITIES PRODUCED AND ANALYSIS OF AEROSOL CONCENTRATION AND PARTICLE SIZE.
B4. CONCLUSIVE ASSESSMENT OF OBTAINED RESULTS AND ELABORATION OF RECOMMENDATIONS FOR THE BEST APPLICATION TO CONCRETE DECONTAMINATION.
