Sellafield plans Calder Hall Turbine Hall B demolition at 70

Summarised from 2 outlets · Updated 17 Oct, 06:08 · Archive

Sellafield has submitted plans to demolish Calder Hall Turbine Hall B as the world's first commercial nuclear power station marks its 70th anniversary.

Sellafield has submitted plans to demolish Turbine Hall B at Calder Hall near Seascale, the world's first full-scale commercial nuclear power station, marking its 70th anniversary. The prior notification was lodged with Cumberland Council on 14 October, just days before the anniversary of the station's opening by Queen Elizabeth II on 17 October 1956.

The demolition forms part of the Calder Land Clearance Project, which aims to remove redundant buildings and free up space for future use. Turbine Hall B contains redundant electricity generation equipment within a steel-framed structure built on a concrete raft, with external walls clad in masonry and asbestos-cement sheeting.

Sellafield awarded Amentum Clean Energy Limited a £14.85 million contract for the demolition, which runs from September 2026 to September 2028, although the planning application gives a wider expected works period ending in November 2031. According to Sellafield, the demolition will 'release a significant land area for reuse' whilst reducing the costs of maintaining a building which is no longer in use. The work would involve removing redundant equipment and assessing waste materials before the building is demolished using a wheeled excavator fitted with attachments.
