Consent for Hinkley Point C Nuclear Island concrete pour

23 November, 2018

The Office for Nuclear Regulation (ONR) has provided NNB Genco (HPC) Ltd (NNB GenCo) with consent to commence the unit 1 Nuclear Island concrete pour at Hinkley Point C (HPC).

The Nuclear Island will contain the unit 1 reactor building, the fuel building and the four electrical and safeguard divisions on one common reinforced concrete base slab. This cross-shaped base slab is known as the common raft.

NNB Genco is constructing a twin reactor European Pressurised Reactor™ (EPR) nuclear power station at HPC in Somerset.  NNB GenCo is the holder of a nuclear site licence for HPC which we granted in November 2012.

Our inspectors will continue to regulate NNB GenCo to ensure that the high standards of safety and security expected in the UK is maintained at HPC.
