Costain Appointed to Magnox Decommissioning Framework

Costain awarded share of £485m programme

Costain Group PLC ("Costain") announces that is has been awarded a place on a new six-year framework for Magnox Ltd. to support the company across 11 sites and deliver its decommissioning programme through to 2029.

The full programme of work, which is worth up to £485m, will contribute to the clean-up of the UK's nuclear waste whilst reducing the environmental impact of the sites and helping to deliver the Nuclear Decommissioning Authority's strategic goals. Costain has secured a position on both Lot 1 and Lot 2 of the framework utilising its full complex delivery and consultancy capability.

Sam White, managing director, Natural Resources, Costain, commented:

"Costain has been implementing innovative solutions to deal with legacy nuclear waste for more than 20 years and these awards build on our decommissioning heritage with Magnox.

"Our previous work across the Magnox fleet has been instrumental in moving sites towards Care and Maintenance - essentially de-fuelling, decommissioning and creating safestores. This work represents a significant milestone along the decommissioning journey towards eventual final site clearance."

Magnox is a wholly owned subsidiary of the Nuclear Decommissioning Authority and Costain's experience will support the safe and secure closure of the Magnox sites.

Paul Winkle, chief operating officer, Magnox said:

"This new decommissioning framework contract builds on the success of the previous one. It is a key, collaborative business tool that will provide an efficient, cost-effective route to market to decommission, demolish or re-use redundant buildings.

"Magnox created a 7,400m2 demolition footprint last year - that's the collective size of 45 tennis courts. This is a significant achievement for the company and all the supply chain partners involved. We're looking to deliver even more this year and the new framework contract will simplify the procurement process to do that."
