UO2펠릿의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. U02F2수용액에 NH3을 더하여 ADU를 침전시켜, 이 ADU로 부터 U02분말을 경유하여 UO2소결펠릿을 얻을수 있는 UO2펠릿의 제조방법에 있어서, 전기한 UO2F2수용액의 U농도를 50-500gU/1로 함과 동시에, 이 U02F2수용액과 NH3을 2단계로 나누워서 반응시켜, 1단계째에는 NH3/U몰비를 3-6으로 2단계째에는 NH3/U몰비를 6-12로 설정함으로서, 결정입경이 10-100μm의 UO2펠릿을 제조하는 것을 특징으로 하는 UO2펠릿의 제조방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
