Study says nuclear waste can be cut 90%

Engineers from the University of Sheffield have developed a way to significantly reduce the volume of some higher activity wastes, which will reduce the cost of interim storage and final disposal.

The researchers, from the University's Faculty of Engineering, have shown that mixing plutonium-contaminated waste with blast furnace slag and turning it into glass reduces its volume by 85-95 per cent. It also effectively locks in the radioactive plutonium, creating a stable end product.The approach could also be applicable to treating large volume mixed wastes generated during the eventual clean-up of the damaged Fukushima plant.
