Decontamination underway at Bradwell

Decontamination milestone reached at Bradwell

More than 10,000m2 of walls, floors and ceilings have been decontaminated at the site of a former nuclear power station in Essex, according to the Nuclear Decommissioning Authority (NDA).

The NDA said that the complex clean-up operation, which covered an area similar to a rugby field, has been the result of four years of work after draining and stabilising “ponds” in 2012. It explained that these ponds were previously used to temporarily store and cool used nuclear fuel before it was sent to a nuclear fuel reprocessing and decommissioning site at Sellafield.

Since 2012, Magnox Ltd, the site licence company responsible for managing the Bradwell site, said that it had continued to work to remove redundant equipment and decontaminate the rest of the associated buildings and infrastructure.

“This has been a major achievement in preparing the site for eventual closure. During the project more than 2.5km of pipework was deplanted and more than 120t of metal waste was recovered and appropriately disposed of,” said Magnox Ltd ponds project manager Trevor Frost.

“I am extremely proud of the team which has safely delivered this project to time and budget.”

The NDA said that one of the next phases of work would be to demolish the redundant ponds building and remaining ancillary buildings, followed by installation of weatherproof cladding over the remaining buildings.

This latest set of works has followed the recent decontamination of underground waste vaults and weatherproof cladding of the reactor buildings.

“The learning gained from reaching these milestones is invaluable as we move into our next phases of work on site and take another important step towards care and maintenance,” added Magnox Ltd’s Bradwell closure director Scott Raish.
