Vitrifying hazardous radioactive waste
Vitrification will bring you a definitive solution for controlling hazards from your wastes and ensuring long-term stability thanks to a safe and proven conditioning approach, the outcome of 40-years’ experience.
-
Succeed in managing your wastes which:
- need a wasteform which is safe and stable over time controling radioactivity impact on environment and humans,
- cannot be routed to standard surface disposal facilities,
- cannot be processed using traditional technologies such as grouting,
- need a wasteform versatile enough to integrate very different chemical elements.
Vitrification is a solution to process radioactive and hazardous wastes that cannot be processed using traditional technologies.
Alone or coupled with other treatment such as organic wastes incineration or melting of metals, it neutralizes the hazardous characteristic of the waste, destroys unwanted reactivity, and produces an inert, stable wasteform, suitable for safe long-term disposal, with attractive volume reduction ratios.
Our vitrification technologies are capable of simultaneously treating your organic, inorganic and metallic wastes, depending on the configuration chosen. A wide range of solutions have been or are currently being developed by Orano:
- In-can process (DEM&MELT),
- Incineration-vitrification in a cold crucible melter (vitrification of ashes coming from organic wastes incineration),
- Plasma-enhanced, incineration-vitrification process (PIVIC – organic wastes incineration before vitrification and metallic wastes fusion),
- Calcination and hot wall melter or cold-crucible melter.
- Waste is transformed into an inert and durable wasteform,
- Significant volume reduction,
- Product ready for final disposal,
- Operable, maintainable, and adaptable facilities, suited to any environment,
- Several technologies available according to waste type and context.
Orano started designing, building, and operating vitrification facilities in the 1970s. To date, French operators have vitrified with their technologies more activity than any other country in the world (357,000,000 Terabecquerels beta-gamma activity incorporated, 9319 metric tons of glass produced since 1989).
Orano, as an operator, has upgraded its technologies to meet the evolving needs arising from current operations, but also to improve the safety of legacy facilities and legacy waste. With the full suite of competencies at Orano’s disposal, from R&D (furnace, bench studies) to engineering and operational experience, Orano is able to study any customer need and to propose the best solution for troublesome waste streams.
For instance, an application is currently under development for miscellaneous waste types from Fukushima remediation operations (sludges, mineral sorbents, soil….). Other applications are being developed for mixed TRU waste, or for waste from D&D.
Orano’s vitrification expertise and solutions will supply definitive elimination of hazards for a wide range of wastes. This will greatly improve site safety and enable significant progress in site decommissioning.
