Office for Nuclear Regulation
The Office for Nuclear Regulation (ONR) is the regulator for the civil nuclear industry in the United Kingdom. Created on 1 April 2011, the ONR is formed from the merger of the Health and Safety Executive's Nuclear Directorate (the Nuclear Installations Inspectorate, Office for Civil Nuclear Security, and the UK Safeguards Office) and, from 1 June 2011, the Department for Transport's Radioactive Materials Transport Team. The change follows the recommendations of a review conducted on behalf of the Government in 2008.
The ONR was initially created as a non-statutory body and an agency of the HSE, however the Government has announced its intention to put the ONR on a statutory basis once the appropriate legislation has been passed. Pending the change, Nick Baldwin, former chief executive of Powergen (now E.ON UK) was appointed part-time interim chair of the ONR on its formation, resigning as a non-executive director of Scottish and Southern Energy. John Jenkins was appointed as Chief Executive of ONR from 1 June 2013, having previously been Chief Operating Officer.
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. The GDA started assessing four designs:
However the ACR-1000 and ESBWR were subsequently withdrawn from the assessment for commercial reasons, leaving the EPR and AP1000 as contenders for British new nuclear builds. Assessment of the AP1000 was suspended at Westinghouse's request, awaiting a firm UK customer before addressing issues raised by the assessment.
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. The ABWR will first require a UK GDA, which is likely to take from two to four years. The assessment was agreed in April 2013.
