ONR is responsible, amongst other things, for regulating licensees that wish to construct and operate (commission) new nuclear power stations at sites in Great Britain.
A nuclear site licence must be in place and this puts the licence holder under strict legal obligations and, importantly, gives wider and deeper regulatory powers to ONR to ensure the safe construction, commissioning and operation of a nuclear site.
ONR's regulatory responsibility starts at the point of granting of a nuclear site licence for a particular site. This continues with the granting of the final Licence Instrument (usually consent to commence operation). We will then use the powers available under the site licence to permission the start of construction and other subsequent key stages.
ONR's responsibilities will include interaction with BEIS, other regulatory bodies, NGOs and other UK and international stakeholders relating to ONR's regulatory framework, strategies and approaches to new reactor construction.
ONR is currently regulating the construction of an EPR reactor at Hinkley Point C in Somerset, the licensee being NNB Genco Limited.
