RADIATION IMPACT DURING THE DECONTAMINATION BY MELTING OF RADIOACTIVE SCRAP METAL ARISEN FROM THE DECOMMISSIONING OF NUCLEAR POWER PLANTS

Andrej Slimák – Vladimír Nečas

   Decontamination of radioactive scrap metal by melting is a prospective technology to reduce the amount of metallic radioactive waste. Melting technology provides a particular advantage of homogenising a number of radionuclides in the ingots and concentrating other radionuclides in the slag and dust filter resulting from the melting process, thus decontaminating the primary material. The presented paper also deals with the evaluation of exposure of the workers during melting of radioactive scrap metal. According to the obtained results, the effective doses absorbed by workers during the melting meets the legislatively given limit 20 mSv per annum.

Keywords: decommissioning, radioactive scrap metal, metal melting
