Conditionnement Déchets Béton (CDB) - Production of concrete containers
The prefabrication firm CDB is a joint subsidiary of SOCODEI (51 %) and SOGEA Construction (49 %).
Its production is mainly oriented towards radioactive waste packaging:
- Reinforced concrete containers
- Dry mix filler
CDB also manufactures reinforced concrete utility poles supporting overhead power lines and operates an alluvial quarry.
The drymixed fillers comprise dry aggregates, cement, and additives that are pre-measured and packaged in flexible containers.
They are used to prepare the concrete for containers, as well as concrete and mortar for encapsulation, grouting and sealing of radioactive waste on nuclear sites.
These are the containers used by the Mercure Unit.
The automated production facility is capable of dosing custom formulations wide range.
The premixed batch weight can vary from 50 to 1000 kg
with less than 1% moisture content and batching.accuracy for each component is ± 2%.
Annual production capacity is 15 000 premixed batches.
Continuous monitoring of raw materials, of the manufacturing process and of the final material ensures the user will receive a quality product.
The company operates an alluvial quarry to obtain the aggregates (which are qualified by EDF to produce durable concrete with a 300-year rating) used to produce the dry premixed batches.
Reinforced concrete containers are used for packaging low and intermediate-level radioactive waste for shipment to a surface storage facility.
Depending on waste type, they may also include internal steel radiological protection liners or filtration systems.
In addition to producing the containers, the company also conducts tests on simulated non-radioactive containers. The packages are subjected to a series of tests required to obtain approval by the regulatory authorities responsible for the transportation and storage of radioactive waste:
primarily package load resistance tests, drop tests, and cutting tests.
