The DDP was established in 2016 and involves 17 supply chain companies working with Sellafield Ltd, to demolish redundant buildings, clean up land and get waste out of the site’s legacy ponds and silos.

Highlights to date have included the demolition of the diffuser on top of the Windscale Pile Chimney and retrieval of waste and sludge from the First Generation Magnox Storage Pond.

The partnership, which has now been extended until 2026, has so far delivered £385 million ($480m) of project work and recorded 4.5 million hours without a lost time accident. Nearly one third (32.4%) of all supply chain spend has gone to small to medium-sized enterprises and the partnership has created 90 new jobs. It aims to increase that job creation number five-fold by the end of the contract.

Glenn McCracken, chairman of the DDP programme board for Sellafield Ltd, said: “We have taken on work through the framework which has been much broader than the vast decommissioning remit, including constructing the new high-security fencing and adapting an existing plant so that it can accept waste from the Magnox Swarf Storage Silo.”

Future projects include clearing land and removing the heat exchangers around the redundant Calder Hall reactors and turbine halls; helping to plan the dewatering of the Pile Fuel Storage Pond; helping Sellafield Ltd to clean up the Thorp and Magnox reprocessing plants; demolishing structures such as the Windscale Pile Chimney.
