First concrete has been poured for the ‘common raft’ of Hinkley Point C, on which the reactor building and safety systems will be constructed. The major milestone in the construction was announced by EDF Energy today. The raft will be a 4500 tonne cross-shaped platform of nuclear grade concrete, reinforced with steel, which will support the reactor building and the fuel building as well as four separate sections for electrical and safeguards systems. EDF Energy said the first 2000 cubic metre portion was poured over 30 hours to a thickness of 3.2 metres. Four more pours will follow before the raft will be complete, scheduled in 2019. Consent for this work was granted by the Office for Nuclear Regulation on 23 November, which judged EDF Energy and its contractors ready to proceed past this so-called hold point. The raft is the second safety-related concrete item to be constructed at Hinkley Point C. In March 2017 EDF Energy placed structural concrete for the technical galleries which run beneath the plant.
