Calder Hall collapsed

1 October 2007

Four iconic cooling towers at Sellafield’s defunct Calder Hall site in England were demolished at the weekend.

The cooling towers, each of which reached 88m tall, have stood as a symbol of the UK nuclear energy programme since the Queen opened Calder Hall in 1956 as the first commercial-scale nuclear power station.

The massive structures took only just over a minute to crumble to the ground following detonation.

Calder Hall consisted of four Magnox units, each rated at 50MWe.

Construction began in 1953 and criticality in each of the four reactors was reached between 1956 and 1958.
