원자력발전소 방사성폐기물(폐윤활유) 자체처분

Abstract

Waste lubricating oil, which is radioactive waste generated from nuclear power plants, is a lubricant for major equipment of nuclear power plants, and is incinerated and buried through regulatory clearance because the possibility of contamination by radioactive materials is low. For regulatory clearance of radioactive waste, it is proved that the radioactive concentration is less than or equal to the radionuclide-specific radioactive concentration prescribed in the Nuclear Safety Act (Tables 1 and 2), and the estimated individual exposure dose is 10 μSv/yr or less, and the total exposure dose to the group is less than 1 manㆍSv/yr. For each radionuclide, one mixed sample per drum is collected and analyzed with a HP-Ge, and the expected exposure dose is evaluated by K-DOSE 60 and RESRAD. Since this waste oil is easy to handle and dispose of and is free from contamination by radioactive materials, it is often disposed of through regulatory clearance. Therefore, it is necessary to carefully examine the process of regulatory clearance of waste oil and widely use it for self-disposal of various radioactive wastes. If this is used for dismantling nuclear power plants, it will be an eco-friendly waste disposal method that is economical, free from radioactive contamination, and enhances public trust.
