Calder Hall towers get a cooling down

Four cooling towers at Calder Hall nuclear power station were brought down this week by explosive demolition by contractor Controlled Demolition.

The destruction of the 50-year-old towers at Calder Hall – the world’s first commercial nuclear power station – forms part of the overall programme of decommissioning works across the Sellafield site in Cumbria.


The towers were 88m high, 58m wide at the base, narrowing to 32m at the top.

Internal workings and structures were removed before more than 5,000 holes were drilled and each charged with explosives.
