| description | PROBLEM TO BE SOLVED: To provide a method for recovering reusable metal from metal contaminated with a radioactive substance while reducing a treating amount of a radioactive waste remains after the metal is recovered.SOLUTION: The method comprising: (a) a step S1 for preparing radioactive contaminated metal contaminated with a radioactive substance; (b) a step S2 for recovering the radioactive substance from the radioactive contaminated metal as a predetermined amount of a low-level radioactive waste; (c) a step S3 for recovering metal from the radioactive contaminated metal from which the predetermined amount of the low-level radioactive waste has been recovered; (d) a step S4 for equivalent exchanging the predetermined amount of the collected low-level radioactive waste with a predetermined amount of a high-level radioactive waste; and (e) a step S5 for preparing, as transportable enclosed solidified bodies, the high-level radioactive waste equivalent to the predetermined amount of the exchanged high-level radioactive waste.
【課題】放射性物質で汚染された金属から再利用可能な金属を回収すると同時に、その金属回収後に残る放射性廃棄物の処理量の低減を図れる方法を提供する。【解決手段】（ａ）放射性物質で汚染された放射性汚染金属を準備するステップＳ１と、（ｂ）放射性汚染金属から放射性物質を所定量の低レベル放射性廃棄物として回収するステップＳ２と、（ｃ）所定量の低レベル放射性廃棄物の回収後の放射性汚染金属から金属を回収するステップＳ３と、（ｄ）回収された所定量の低レベル放射性廃棄物を所定量の高レベル放射性廃棄物と等価交換するステップＳ４と、（ｅ）交換された所定量の高レベル放射性廃棄物に相当する高レベル放射性廃棄物を輸送可能な密封固化体として準備するステップＳ５と、を含む。【選択図】図１ |
