Claims (9)

  1. 방사성물질에 의해 표면이 오염된 금속을 전해제염하는 방법에 있어서 중성염의 수용액을 전해액으로서 사용하여 제염대상금속을 교번전해 함으로써 방사능으로 오염된 산화피막층 및 금속표면을 제거하는 것을 특징으로 하는 방사성오염속의 제염방법.
  2. 상기 교번전해에 있어서, 음국전해시간을 양극전해시간의 2∼10배로 하는 것을 특징으로 하는 톡허청구의 범위 1기재의 방사성 오염금속의 제염방법.
  3. 중성염은 염산염, 황산염, 질산염 및 인산염으로 이루어진 군에서 선택된 1종 또는 2종 이상의 염인 것을 특징으로 하는 특허청구의 범위 1기재의 방사성 오염금속의 제염방법.
  4. 방사성물질에 의해 표면이 오염된 금속을 제해제염하는 방법에 있어서, 중성염의 수용액을 전해액으로서 사용하여 제염대상금속을 교번전해함으로써 방사능으로 오염된 산화피막층 및 금속표면을 제거하며, 이어서 전해액중에 포함되는 제염잔사를 분해하여, 이 잔사에 고화재를 가하여 고화하는 것을 특징으로 하는 방사성오염속의 제염방법.
  5. 상기 교번전해에 있어서 음극전해시간을 양극전해시간의 2∼10내로 하는 것을 특징으로 하는 특허청구의 범위 4기재의 방사성오염금속의 제염방법.
  6. 중성염은 염산염, 황산염, 질산염 및 인산염으로 이루어진 군에서 선택된 21종 또는 2종 이상의 염인 것을 특징으로 하는 특허청구의 범위 4기재의 방사성오염금속의 제염방법.
  7. 상기 제염잔사의 분리, 고화에 있어서 제염잔사를 탈수농축후, 물유리와 혼합하여 고화하는 것을 특징으로 하는 특허청구의 범위 4기재의 방사성오염금속의 제염방법.
  8. 상기 제염잔사의 탈수농축에 있어서, 원심분리법을 사용하는 것을 특징으로하는 특허청구의 범위 7기재의 방사성오염금속의 제염방법.
  9. 제염잔사와 물유리와의 혼합비는 1 : 2∼1 : 3인 것을 특징으로 하는 특허청구의 범위 7기재의 방사성오염금속의 제염방법.
