Office for Nuclear Regulation

The Office for Nuclear Regulation (ONR), colloquially known as Ofnuke, is the safety regulator for the civil nuclear industry in the United Kingdom.[1] It is an independent statutory corporation whose costs are met by charging fees to the nuclear industry. The ONR reports to the Department for Work and Pensions, although it also works closely with the Department of Energy and Climate Change.[2]


The establishment of the ONR followed a 2008 review conducted on behalf of the Government into the regulation of the UK civil nuclear industry, recommending the creation of a single industry specific regulator.[3]

It was initially created on 1 April 2011 as a non-statutory agency of the Health and Safety Executive (HSE), with the Government intending to put the ONR on a statutory basis at a later date.[4][3]

The ONR was formed from the merger of the HSE's Nuclear Directorate (the Nuclear Installations Inspectorate, the Office for Civil Nuclear Security and the UK Safeguards Office) and from 1 June 2011, the Department for Transport's Radioactive Materials Transport Team.[3]

Nick Baldwin, former chief executive of Powergen (now E.ON UK) was appointed part-time interim chair of the ONR on its formation,[1] resigning as a non-executive director of Scottish and Southern Energy.[5] John Jenkins was appointed as Chief Executive of ONR from 1 June 2013,[6] having previously been Chief Operating Officer.[7]

Legislation to establish the ONR was included in the Energy Act 2013, and it was formally launched as an independent statutory corporation on 1 April 2014.[8]

John Jenkins resigned from his post on 28 February 2015 and was replaced by Les Philpott on 1 March 2015 as the Interim Chief Executive. Adriènne Kelbie was appointed Chief Executive and took up the appointment on 18 January 2016.[9]

Generic Design Assessment process

Following the 2006 Energy review the Nuclear Installations Inspectorate developed the Generic Design Assessment process (GDA), now operated by ONR, to assess new nuclear reactor designs ahead of site-specific proposals.[10] The GDA started assessing four designs:

However the ACR-1000 and ESBWR were subsequently withdrawn from the assessment for commercial reasons,[11][12] leaving the EPR and AP1000 as contenders for British new nuclear builds.[13][14] Assessment of the AP1000 was suspended at Westinghouse's request, awaiting a firm UK customer before addressing issues raised by the assessment.[15]

In 2012 Hitachi purchased Horizon Nuclear Power, announcing intent to build two to three 1,350 MWe Advanced Boiling Water Reactors (ABWR) on both of Horizon's sites.[16] The ABWR will first require a UK GDA.[17] The assessment was agreed in April 2013,[15] and is likely to take about four years.[18]

On 21 September 2015 Energy Secretary Amber Rudd announced that a Chinese designed nuclear power station was expected to be built at Bradwell nuclear power station. The reactor chosen will first require a UK GDA.[19][20]

Although the ONR is primarily a civil regulator, it has responsibility for assessing the response systems for nuclear weapon accidents at HMNB Clyde and RNAD Coulport, in Argyll, Scotland.[21]
