AI Article Summary

EDF Energy has utilized the world's largest construction crane, 'Big Carl', to lift a 245-ton dome onto a nuclear reactor building at Hinkley Point C in Somerset, UK. This new nuclear plant, including twin reactors, is the first to be constructed in Britain in 30 years and aims to provide clean electricity to over six million homes. The project utilizes prefabrication methods to accelerate the build process and is expected to be completed by 2031, despite initial delays. Costing £26 billion, this project is part of the UK government's initiative to advance nuclear power and enhance energy security.
