Applications Overview

Kurion’s waste separation and stabilization solutions are used to treat nuclear and hazardous waste around the world. Its Ion Specific Media (ISM) separation technology is known for its contribution to the cleanup at the Fukushima Daiichi Nuclear plant following the March 2011 earthquake and tsunami. Kurion’s GeoMelt® In-Container Vitrification (ICV™) and Sub-Surface Planar™ processes have been in commercial use since the 1990s and have treated in excess of 26,000 tons of waste in the U.S., Japan and Australia.

Following is a sample of the most prominent and meaningful applications to demonstrate the diversity and reach of Kurion’s solutions, as well as the familiarity of the Kurion staff with very different regulatory environments.

Wastewater Treatment at Fukushima Daiichi Nuclear Plant
Fukushima, Japan

Kurion delivered the first-ever external cooling system for a nuclear reactor, which was responsible for 70% of the radioactivity removed from the water in the first nine months of operation


Bulk Vitrification of Low-Activity Waste
Hanford, Wash.

This multi-year project was designed to demonstrate the feasibility of Kurion’s GeoMelt® In Container Vitrification (ICV™) process (also referred to as bulk vitrification for this project) as a supplemental treatment technology for Hanford’s Low-Activity Waste

Hazardous and Toxic Waste Treatment across Japan

Through ISV Japan, a sublicense holder of GeoMelt® technology, GeoMelt® completed dozens of melt operations at all scales to treat hazardous and toxic waste 

PCB Treatment
Spokane, Wash.

The 1994 project demonstrated the ability of the GeoMelt® technology to meet TSCA treatment requirements and to treat various types of PCB-contaminated debris

Contaminated Soil at Nuclear Weapons Site
Maralinga, South Australia

GeoMelt® vitrification technology was selected in 1989 for a decade-long project to stabilize contaminated soil from above-ground nuclear testing dating back to the 1950s and 1960s

In-Situ, Top-Down Treatment
Grand Ledge, Mich.

GeoMelt® demonstrated its first large-scale commercial application in 1994 for its in-situ, top-down melting process to treat contaminated soil at the site of a former chemical plant

Sellafield Thermal Treatment Development Program
Seascale, England

The GeoMelt® In-Container Vitrification (ICV™) technology was shown to be effective in this proof-of-concept test to treat a range of waste streams at the Sellafield site
