The UK’s National Nuclear Laboratory (NNL) has launched a joint project with US waste treatment company Kurion to deploy a full-scale In-Container Vitrification (ICV) plant based on Kurion’s GeoMelt technology at NNL’s flagship Central Laboratory on the Sellafield nuclear reprocessing site.
Kurion’s systems minimize and stabilize nuclear and hazardous waste through two families of technologies: separation and stabilization. Kurion’s separation technology segregates radioactive elements and includes the company’s Ion Specific Media, which is currently deployed at the Fukushima Daiichi Nuclear Power Plant for cesium removal, and its Modular Detritiation System to separate tritium from contaminated water.
Kurion’s stabilization technology converts waste into a leach-resistant glass through vitrification. The company’s GeoMelt vitrification technology is used for treating solid and bulk waste, while its Modular Vitrification System is used for liquid waste.
Kurion acquired the GeoMelt technology in 2012. GeoMelt has been in commercial use since the 1990s and has successfully treated over 26,000 tons of waste in the US, Japan and Australia, the company says.
