Abstract
원자력 시설 해체시 발생되는 금속성 폐기물의 용융 제염을 위한 기초 연구를 위해 아크 용융로를 사용하여 스테인레스강과 탄소강의 금속 폐기물 용융시 슬래그 종류, 농도, 염기도에 따라 60Co, 137Cs 핵종의 주괴, 슬래그, 분진 상으로 분배 특성을 살펴보았다. 60Co은 90% 이상 주괴상에 균질하게 분포되었으며, 슬래그 상에는 약 10% 미만으로 잔존하며 슬래그 조성에 따라 분배특성이 크게 영향을 받지 않았으나, 유동성이 좋은 염기성 슬래그 형성제가 포함된 슬래그에서는 영향을 받음을 알 수 있었다. 137Cs는 스테인레스강과 탄소강의 용융체로부터 완전히 제거되어 슬래그상과 분진상 상으로 분배됨을 알 수 있었다.
A fundamental study on the melt decontamination of metal wastes generated by dismantling the nuclear facility, the melting of metal wastes such as stainless steel and carbon steel have been carried out to investigate the distribution phenomena of the radioisotopes such as 60Co and 137Cs into the ingot, slag and dust phases by using the various slag types, slag concentration and basicity in an arc furnace. The 60Co remained homogeneously in the ingot phase above 90 % and it was barely present in the slag below 10 %. The effect of the slag composition on the distribution for Co-60 was not considerable, but a basic slag former with high fluidity showed effective. 137Cs was completely eliminated from the melt of the stainless steel as well as the carbon steel and distributed to the slag and the dust phase.
