The second of three prefabricated steel rings to form the reinforced cylinder around the nuclear reactor at Hinkley Point C has been lifted from the bunker in which it was constructed to a lay-down area by “Big Carl”, the world’s largest land-based crane. The ring – which is 17m tall and 47m wide – is now being prepared for the final lift into the first reactor building. It was constructed in factory conditions in the bunker – one of the innovations to improve quality on the project. Prefabrication inside these bunkers reduces the need to work at height or in bad weather and the work can be completed and checked in a controlled setting. Big Carl lifted the first ring into place in December. The second ring was built 36% faster than the first due to the teams’ construction experience. During the project, Big Carl will lift more than 500 prefabricated steel and concrete elements weighing up to 1,600t.
