Bentonite Absorber Blocks
Bentonite Absorber Blocks (B.A.Bs) are a high-precision, engineered cement-based radionuclide absorbing and retaining system used to absorb low level active liquid and PCM nuclear waste, before encapsulation.
Developed by Smith Engineering, the B.A.B. is manufactured at the absorbent block plant within the Maryport facility.
It has been used extensively by Sellafield Ltd for 20 years in the liquid barrier lining in the base of their low level waste containers (containing PCM waste) at the above ground LLW Repository at Drigg, Cumbria.
The stable long term storage nature of the B.A.B. makes it the only suitable product for this task.
