Decreasing the volume of radioactive effluents
Safe and efficient solution to minimize the volume of your high active liquid waste storage before ultimate conditioning.
-
High Active Liquid Waste (HALW) management needs:
- Concentrate HALW into a manageable volume for temporary storage and optimize concentration in order to prepare final conditioning,
- Demonstrate to Safety Authorities their safe management,
- Design process and equipment remotely operable, inspectable and maintainable allowing management of the decay heat,
- Design equipment compatible with lifetime needs and remaining space in the area, and as cost-effective as possible.
Evaporation of HLW in specifically tailored evaporators is a very efficient solution to concentrate such waste.
A wide range of evaporators and evaporation units have been developed by Orano since the 1960s and are regularly optimized taking into account operator feedback, R&D progress, advances in technologies and regulations, and specific operator constraints and requirements.
- Proven safety and reliability
- Volume reduction
- Management of suspended solids, precipitates or foams
- Concentrates ready for conditioning
- Reagent recovery and recycling
- Distillates ready for site liquid waste facility
- Operable, inspectable, maintainable, and adaptable facilities
Orano started designing, manufacturing, and operating high active evaporation facilities in the 1960s, for laboratory waste treatment to large reprocessing plant fission products or D&D waste concentration or acid recovery.
Orano, as an operator, has developed its processes and technologies to meet ever-increasing process requirements as well as improving safety. The Orano evaporators are thus able to manage corrosive ions, strong acid, or base conditions, precipitates or suspended solids as well as foams, and to offer a service life tailored to the needs.
Orano also developed solutions for in-service inspection, and when need be for life extension of high active waste evaporators, on its own sites as well as on customer sites.
With this full suite of competencies, from R&D to engineering, manufacturing and operational experience, Orano can study customer needs and propose the best suited solutions for HALW evaporators.
