Outline of Final Research Achievements

After the accident in the Fukushima Dai-ichi Nuclear Power Plant. There are also concerns that a large amount of radioactive concrete waste will be generated due to the decommissioning in the future. Although conventional techniques are effective in decontaminating concrete floors and walls, it is not clear what techniques to apply for decontaminating radioactive concrete debris.
In this study, focusing on a pulsed power discharge technique, its applicability of the technique was evaluated to decontaminate radioactive concrete debris using those generated associated with the accident in the Fukushima Dai-ichi Nuclear Plant. Decontamination of concrete by the technique using the pulsed power discharge was evaluated. Results have suggest that the separation into aggregate and sludge of he contaminated concrete debris could achieve decontamination and volume reduction of the radioactive concrete debris.

Academic Significance and Societal Importance of the Research Achievements

既存のコンクリート除染技術は,床や壁等のフラットな表面形状を対象としたものがほとんどであり,表層や浸透層を物理的・機械的に切削,破砕して除染するものが多い。これらの技術は,諸外国の原子炉解体や除染作業で遠隔装置化され実証されている技術である。一方で,瓦礫等の複雑形状の廃棄物を除染する技術は事例が少なく,機械的除染では容易に近づけるフラットな表面に対して有効で,裂け目,接続部や接近を制限された場所の除染は困難または不可能でる。しかし汚染した部位を除去して汚染していない骨材の高度再生処理技術としてパルスパワー援用による本技術はコンクリートの形状に拘らず適用できる世界初の除染技術として期待される。
