The reactor building dome has been lifted into place at the first new EPR nuclear power unit under construction at Hinkley Point C in Somerset, southwest England.
The world’s largest crane, nicknamed “Big Carl”, was used to place the dome, which is wider than the dome of St Paul’s Cathedral in London, on top of the Unit 1 nuclear reactor in Somerset.
The 820ft (250m) crane was deployed to place a 47m-wide dome on top of the reactor on Friday.
The 245-tonne steel dome is the top part of the reactor building’s inner containment – a steel cylinder encased in concrete. Installation of the roof allows the station’s first reactor to be installed next year.
