原子力プラントの廃止措置に伴う鉛ブロックの切断手法の研究開発

Nuclear power plants and research facilities that use radioactive materials employ lead to shield against radiation. Lead must be cut to an appropriate size before being removed from the facility as waste. Because lead is soft, it is difficult to cut using mechanical cutting methods such as reciprocating saws. In this study, we attempted to make lead into a low-melting-point alloy of bismuth and tin (eutectic point 95 °C) and devised a new …
