Waste Conditioning Technology of Radiocontaminated Soil

A special conditioning way for low level soil contaminated by ²⁴¹Am was discussed. Firstly, the contaminated soil was condensed in package container (200 L drum) by 20 t pressing machine. The contaminated soil was pressed from loose state to compaction state, and the volume reduction rate was from 1.1 to 1.4. Secondly, cement with thickness of 10 cm to 15 cm was poured on the package container for sealing. Thus, a cement sealing member was made up by contaminated soil and it could be described as normal solid waste. Finally, taking the cement sealing member as conditioning object, using Ⅶ steel trunk as package container and cement conditioning, Ⅶ steel trunk package was got. Through radiation monitoring, the Ⅶ steel trunk package can satisfy the transport requirement of radiation waste. Also, it can satisfy the accept and disposal requirements of national repository.
