Objective
THIS RESEARCH WORK IS AIMED AT THE ASSESSMENT OF NEW PROCEDURES IN THE FRAMEWORK OF THE DECOMMISSIONING OF A PLANT FOR THE PRODUCTION OF MATERIAL TEST REACTOR (MTR) AND THORIUM HIGH TEMPERATURE REACTOR (THTR) FUEL ELEMENTS.
IMPORTANT ISSUES IN THIS WORK ARE THE PREPARATION OF DETAILED URANIUM AND THORIUM CONTAMINATION DISTRIBUTION MAPS IN WALLS ANF FLOORS, THE EXECUTION OF VARIOUS DISMANTLING AND DECONTAMINATION OPERATIONS UNDER HEALTH PHYSICS CONTROL, THE LARGE-SCALE TREATMENT OF ARISING PRIMARY WASTE AND THE MINIMISATION OF SECONDARY WASTE. THE WORK WILL BE CONCLUDED WITH AN ASSESSMENT OF GAINED EXPERIENCE, WITH POSSIBLE RECOMMENDATIONS FOR FUTURE WORK ON SIMILAR FACILITIES.
IN A SUPPLEMENTARY AGREEMENT, THE INITIAL WORKPROGRAMME WAS MODIFIED, ACCOMPANIED BY A REDUCTION OF THE EC FUNDING OF 48 KECU.
New procedures have been tested for use in the decommissioning of a plant used for producing material test reactor (MTR) and thorium high temperature reactor (THTR) elements.
B.1.- PREPARATION OF A MAP OF THE DISTRIBUTION OF THE CONTAMINATION WITHIN DIFFERENT PARTS OF THE FUEL FABRICATION PLANT.
B.2.- DETERMINATION, BY ANALYSES OF REPRESENTATIVE SAMPLES, OF THE PENETRATION DEPTH OF URANIUM AND THORIUM IN VARIOUS PARTS OF THE FACILITY.
B.3.- CONTROLLED DECONTAMINATION AND DISMANTLING OF THE INTERNAL COMPONENTS AND OF ALL AUXILIARY EQUIPMENT OF THE PLANT.
B.4.- ASSESSMENT OF APPROPRIATE CONDITIONS FOR THE REMOVAL OF CONTAMINATION FROM THE WALLS OF THE FACILITY.
B.5.- DECONTAMINATION OF THE FLOORS AND THEIR REMOVAL.
B.6.- TESTING OF NEW DECONTAMINATION PROCEDURES FOR LESS ACCESSIBLE PARTS.
B.7.- DETERMINATION OF THE RESIDUAL ACTIVITY OF METALLIC SCRAP.
B.8.- DEVELOPMENT OF A LARGE SCALE FACILITY FOR FREE RELEASE BY GAMMA-DETECTION OF WASTE FROM A FUEL ELEMENT FABRICATION FACILITY.
B.9.- DEVELOPMENT OF METHODS FOR LARGE-SCALE DECONTAMINATION OF DEMOLITION RUBBLE.
B.10.- EVALUATION OF OBTAINED RESULTS.
