Abstract

핵연료의 가공공정에서 발생하는 스러지를 건식처리공정으로 회수 정제할 수 있는 건식처리 방법에 대하여 논의하고자 하였다. 건식처리방법은 수용액을 전혀 사용하지 알기 때문에 폐기물의 발생량이 습식처리방법에 비해 훨씬 줄어든다. 산화우라늄은 고온의 용융염중에서 염소개스에 의해 염소화반응을 통하여 우라늄염화물을 생성되게 되어 이들은 전기적으로 이동이 가능한 형태로 바뀌므로 전극에 선택적으로 전착될 수 있기 때문에 다른 금속이온과 분리할 수 있다. 본 보고서에서는 산화우라늄의 염소화공정, 전착공정에 대하여 기술하였고 전착된 산화물의 물리적 특성에 대하여 요약하였다.
