이동형 방사화학 분석시설에서의 해체 금속폐기물 전처리작업자 피폭 평가 연구

Abstract

Radioactive waste generated by nuclear facilities has various shapes and levels, soaccurate source terms must be derived. In the case of nuclear power plants, metal and concretewastes account for a large proportion of the decommissioning waste. In addition, since the wastesubject to clearance accounts for more than 90%, rapid radiochemical analysis is required. This study to preliminarily evaluate the external exposure of pretreatment workers in a mobileradiochemical analysis facility to analyze wastes generated when decommissioning a nuclearpower plant. In pre-treatment work, the point source method and point kernel method were usedto evaluate external exposure. Preliminary evaluation results were derived by using the inputfactors (source term, sample size, time, etc.) expected to be applied at the mobile radiochemicalanalysis facility.
