New build/Construction


ONR is responsible for regulating licensees that wish to construct and operate new nuclear power stations at sites in Great Britain.

Before construction can begin, a nuclear site licence covering the area where the new reactor(s) will be located, must be in place. This puts the licence holder under strict legal obligations and, importantly, gives ONR powers to ensure the safe construction, commissioning and operation of the power station.

ONR's activities include interaction with BEIS, other UK regulatory bodies, NGOs and other UK and international stakeholders with an interest in our regulatory strategies and approaches to new reactor construction.

Current activities

ONR is currently regulating the construction of a nuclear power station at Hinkley Point C in Somerset, the licensee being NNB Generation Company (HPC) Limited.
