METHOD AND DEVICE FOR DECONTAMINATING METAL PROFILES SOILED BY RADIOACTIVITY

摘要

The present invention relates to a process for decontaminating metal profiles that are hardened by radioactivity. According to this method, the sections 5 are displaced in relation to rotary wire brushes 6, 7, 8. 9 IN ORDER TO ELIMINATE THE SOILS UNDER THE MECHANICAL ACTION OF THESE BRUSHES TO WHICH ARE SUBJECTED THE SURFACES OF THE PROFILES. THE SOIL THUS MECHANICALLY DETACHED IS THEN FILLED (IN 14) IN A CURRENT AIR, BY A SEPARATION OF DUSTS IN TWO STEPS. THE LOW VOLUME OF RESIDUES MAY THEN BE CLOSED AT THE EXIT OF THE SEPARATORS TO BE EVACUATED. / P P APPLICATION TO THE CLEANING OF THE METALLIC ELEMENTS CONSTITUTING THE SCAFFOLDING USED FOR REPAIR WORK IN THE NUCLEAR POWER PLANTS. / P
