Hinkley Point C: 170 tonne prefabricated part lifted into place

The 250m tall nicknamed ‘Big Carl’ crane lifted a 170 tonne prefabricated part of the reactor’s steel containment liner into place.

The achievement marked the end of a year where all the milestones for the new nuclear power station were met.

As well as being a great feat of skill, the lift is considered by EDF an important example of innovation. Using lessons learned from EPR construction around the world, the liner section was welded and prefabricated under cover in factory conditions on site to improve quality and lower schedule risk.

Other major achievements in 2019 included:

• Completion of the first reactor’s base


• Start of tunnelling on the three water cooling intakes deep beneath the Severn Estuary


• Completion of the 760m seawall


• Hiring of the 500th apprentice


• Construction of first permanent buildings above ground

The project is now focused on completing the base of Unit Two in 2020, as planned, 12 months after Unit One. Productivity improvements between the two units show the benefit of replication and using experienced workers repeating the same design. This approach will be used for the proposed near-identical plant at Sizewell C in Suffolk.

The project is also strengthening UK skills by joining in the creation of a national welding centre in Somerset, a UK nuclear Technical Services Organisation in Gloucester and a UK EPR engineering design centre in Bristol.

Hinkley Point C managing director Stuart Crooks said: “The first big lift is another impressive achievement and I want to thank the teams who’ve worked so hard to make this possible. The experience from civil and nuclear construction and operation across the world at Hinkley Point C is first class and I am pleased to say that we have ended 2019 with all milestones achieved.

“We know that Hinkley Point C’s success is essential in the fight against climate change – in a future when renewables and nuclear will be needed to fill an energy gap as we move away from polluting fossil fuels.”
