Fabrication and Characteristics of $UO_{2+x}$ Powder by a Dry Conversion Process

건식 변환 공정에 의한 $UO_{2+x}$ 분말 제조 및 특성

  • Published : 2000.02.01

Abstract

Nuclear fuel $UO_{2+x}$ power was produced from concentrated $UF_6$ by the DCP(Dry Conversion Process). The characterstics of $UO_{2+x}$ powder, prepared with respect to steam flowing conditions and temperature variations in a rotary kiln reactor, have been investigated with a uranium analyzer, water vapor measurement, and SEM. Fluorine content of the powder could be reduced to 8ppm. The moisture content was found to be optimized.

농축 우라늄 $UF_6$로 건식법 중의 하나인 DCP법으로 핵연료 $UO_{2+x}$ 분말을 제조하였다. Rotary kiln 내로 수증기를 주입할 때 일어나는 온도 변화에 따른 $UO_{2+x}$ 분말 특성을 우라늄 분석기, 수분 측정기, SEM 등으로 측정하였다. 그 결과 불소의 함유량은 8ppm을 나타냈고, 수분 함량의 경우 최적화되었음을 알 수 있었다.
