The building now stands at more than 32 metres tall, changing the skyline at the site, EDF Energy said. 

The steel ring forms part of the reactor building and was prefabricated in an onsite factory before being lifted into place by the 250m tall crane.

The team worked through the night, waiting for suitable weather conditions to lift it into place. EDF Energy said the lift demonstrates the "remarkable momentum" being made on the project. 

“This year marks a new phase for the site, with work being carried out to install pipes and electrical cables across the power station.” The UK's Office for Nuclear Regulation (ONR), granted permission for the start of bulk mechanical, electrical and heating, ventilation and air conditioning (MEH) work in January.
