International Atomic Energy Agency (IAEA) organized an expert mission in Liverpool to assess progress by the UK’s Office for Nuclear Regulation (ONR) in addressing findings from prior IRRS peer review missions. The 4–7 November 2014 mission reviewed legislative and governmental responsibilities, regulatory body functions, management system, authorization, and additional occupational radiation protection and related radiation-source and waste-management areas. The mission noted ONR’s transition to an independent public corporation and consolidation of its “One ONR” operating model, with most 2009 and 2013 findings closed and new recommendations issued.

The purpose of the 2013 peer review mission was to review measures undertaken following the recommendations and suggestions of the 2006 and 2009 IRRS missions and to review the areas of waste management and decommissioning, occupational radiation protection and radiation sources application in order to ensure ONR had received an IRRS mission covering all ONR regulatory functions. The IAEA was also requested to review ONR’s approach to openness and transparency as well as the recently implemented ONR operating model. All except one of the suggestions from 2009 were closed and the 2013 IRRS mission resulted in 12 new suggestions and 13 new recommendations. The IRRSteam at that time identified this as a ‘commendable’ result by the ONR. In June 2014, the UK Government requested the International Atomic Energy Agency to carry out a progress review mission to the UK, following on from the series of missions to the UK in 2006, 2009 and 2013. This request is the first time a member state has requested assessment against findings within a year of a peer review mission, and again the expert mission commends ONR for the support they have shown to the process, and its findings. The expert mission took place from 4 to 7 November 2014 at the ONR headquarters in Liverpool. The expert team consisted of three senior regulatory experts from three IAEA Member States and three IAEA staff members. The team carried out a review of the progress made with actions to address the findings from the previous IAEA regulatory-peer-review missions in the following areas: legislative and governmental responsibilities, responsibilities and functions of the regulatory body, management system of the regulatory body, authorization, and the additional areas of occupational radiation protection, control of discharges, radiation source applications, waste management facilities and decommissioning. The expert team made the following general observations: Since the 2013 Mission, a new Chief Nuclear Inspector was appointed in November 2013 and ONR has become an independent Public Corporation as of 1 April 2014. The UK nuclear regulatory body has been in a state of transition from the first 2006 IRRS mission until its establishment as an independent Public Corporation in April 2014. The change of responsibilities with a broader remit in th
