DEVELOPMENT OF VIBRATORY DECONTAMINATION WITH ABRASIVES.

Objective

THE OBJECTIVE OF THE RESEARCH IS TO DEVELOP A TECHNIQUE FOR THE DECONTAMINATION OF NUCLEAR COMPONENTS USING VIBRATORY EQUIPMENT WITH SELF-CLEANING ABRASIVES GENERATING A MINIMUM QUANTITY OF WASTE.
THE DEVELOPMENT IS AIMED AT THE FOLLOWING GOALS:

- DECONTAMINATION OF METAL AND NON-METAL ITEMS,
- DECONTAMINATION WITHOUT PERSONNEL ATTENDANCE,
- HIGH DECONTAMINATION FACTORS WITH MINIMUM WASTE GENERATION,
- SELF-DECONTAMINATING EQUIPMENT WHICH LOWERS THE OCCUPATIONAL RADIATION EXPOSURE AND CAN BE INSTALLED AS MOBILE UNITS.

THE RESEARCH WILL SEEK FOR THE BEST ABRASIVES WHICH DO NOT RETAIN CONTAMINATION BUT GENERATE A HIGH DECONTAMINATION FACTOR AND A MINIMUM VOLUME OF WASTE, AS WELL AS FOR THE EQUIPMENT REQUIRED TO HANDLE NUCLEAR COMPONENTS DURING THE PROCESS. THE RESEARCHED PROCESS WILL NOT REQUIRE OPERATION PERSONNEL EXCEPT FOR LOADING AND UNLOADING THE COMPONENTS.

B.1 OPTIMIZATION OF THE VIBRATORY TECHNIQUE INCLUDING THE STUDY OF VARIOUS FREQUENCIES AND ABRASIVES.
B.2 CONSTRUCTION OF A SMALL PROTOTYPE OF THE DEFINED VIBRATORY DECONTAMINATION SYSTEM.
B.3 TESTING OF THE PROTOTYPE ON NON-RADIOACTIVE METAL (STAINLESS STEEL AISI 304 AND 316) AND NON-METAL (GLASS, PLASTICS, ETC.) SAMPLES
B.4 DECONTAMINATION TESTS ON CONTAMINATED METAL AND NON-METAL SAMPLES INCLUDING DETERMINATION OF THE DECONTAMINATION FACTORS.
B.5 ASSESSMENT OF THE ARISINGS AND THE TREATMENT OF SECONDARY WASTE, AND EVALUATION OF THE COST AND RADIOLOGICAL CONSEQUENCES OF DECONTAMINATION.
