본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (8)

  1. 가압 수형원자로의 일차계 표면으로부터 방사성 핵종으로 오염된 산-불용성 부식생성물을 오염 제거시키는 방법, 특히 오염된 표면을 산용액 중에서 산화제와 접촉시키고 산화에 의해 산용해성으로 만든 부식 생성물을 용해시킴으로써 크롬-니켈-철 합금으로부터 신화크롬(III)을 오염 제게시키는 방법에 있어서, pH7 이하이고 질산세륨, 크롬산 및 오존을 오염제거가 얻어지도록 하는 농도로 포함하는 물-기제의 산화제로 산화를 수행하는 것을 특징으로 하는 오염 제거방법.
  2. 제1항에 있어서, 산화제는 포화용액 및 분산된 형태로 질산세륨과 크롬산 및 오존의 산성수용액인 것을 특징으로 하는 오염 제거방법.
  3. 제1항에 있어서, 산화제는 2-상 오존가스-수성 혼합물인데, 여기서 기체상의 오존은 질산세륨과 크롬산의 산 수용액에 분산되어 있는것을 특징으로 하는 오염 제거방법.
  4. 제1항에 내지 제3항중 어느 하나에 있어서, 산화 및 용해는 하나의 같은 단계로 수행되는 것을 특징으로 하는 오염 제거방법.
  5. 제1항 내지 제4항중 어느 하나에 있어서, 산화 및 용해는 약 60℃ 이하의 온도, 바람직하게는 약 25℃ 이하 그리고 특히 바람직하게는 약 20℃ 이하의 온도에서 수행되는 것을 특징으로 하는 오염 제거방법.
  6. 제1항 내지 제5항중 어느 아나에 있어서, 물-기제의 산화제는 질산으로 산성으로 만드는 것을 특징으로 하는 오염 제거방법.
  7. 제6항에 있어서, 물-기제의 산화제는 pH 값이 약 1인 산성으로 만드는 것을 특징으로 하는 오염 제거방법.
  8. 제1항 내지 제7항중 어느 하나에 있어서, 질산세륨의 농도는 0.01-50g/l, 바람직하게는 0.5-2g/l이고 크롬산의 농도는 0.01-50g/l, 바람직하게는 0.05-0.2g/l이고, 오존의 농도는 0.001-1g/l, 바람직하게는 0.005-0.015g/l인 것을 특징으로 하는 오염 제거방법.
