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.
Safe and cost effective volume reduction of HALW allowing easier storage management and optimized final conditioning process.- Significant volume reduction (by a factor 10-100 according to waste),
- Concentrates ready for transfer to storage and final conditioning, including any suspended solids
- Acids/bases recovery for recycling achievable,
- Recovered water decontaminated to desired level, down to site low-level thresholds if need be,
- Chemical hazards analyzed and taken care of in the process and equipment design to ensure safe operation,
- Nuclear hazards (including criticality, decay-heat, radiolysis, contamination and irradiation) analyzed and taken care of in the process and equipment design to ensure safe operation,
- Remote inspection of pressure vessels possible,
- Proven safety, operability and maintainability (60 years track record),
- Solutions tailored to the exact customer need (type of waste, type of hazards, activity level, required throughput, layout constraints, site configuration, life-time requirements, life-time increase…),
- Expertise and R&D knowledge, design, manufacturing and operation expertise provided throughout the customer’s project.
