Abstract

6플루오르화 우라늄에서 2산화 우라늄을 제조하는 회전식 건조로는 입구조립체와 가열된 회전통을 갖는다. 6플루오르화 우라늄과 수증기는 입구 조립체에서 함께 반응하여 회전식 스크롤 공급장치 도움으로 통에 공급될 플루오르화 우라닐을 형성한다. 통속에서, 플루오르화 우라닐은 수증기와 수소의 역류와 반응하여 2산화 우라늄을 제조한다. 다공성 금속 또는 세라믹 필터를 스크롤 공급장치에 밀접하게 설치하고 건조로 생성기체로부터 입자를 제공한다. 필터는 청결한 조건으로 유지되도록 스크롤 공급장치 일부인 다수의 반구형 날의 스크랩 작용을 받는다. 건조로에서 생성된 2산화 우라늄 분말은 처리하여 핵연료 펠릿을 제조한다.
