Disposal Methods on Solid Wastes from Mines in Transition Waste Management Overview World Nuclear Association

The important issues on disposal of solid wastes from metal mines are to choose the right varieties for the comprehensive utilization of mining waste and to control contamination from waste rocks and tailingsNuclear power is the only large scale energy producing technology that takes full responsibility for all its waste and fully costs this into the product The amount of waste generated by nuclear power is very small relative to other thermal electricity generation technologi Used nuclear fuel may
