[en] In 2015, Ireland underwent an IRRS (Integrated Regulatory Review Service) review mission. The purpose of the mission was to review Ireland’s radiation and nuclear safety regulatory framework and activities against the relevant IAEA safety standards, to report on the regulatory effectiveness and to exchange information and experience in the areas covered by the IRRS. The review mission was well-timed as there had been recent changes in the regulatory infrastructure with the merger of the Radiological Protection Institute of Ireland (RPII) and the Environmental Protection Agency (EPA) in 2014, as well as the upcoming implementation of the new Euratom Basic Safety Standards (BSS) Directive. The key objectives of the mission were to enhance the national legal, governmental and regulatory framework for nuclear and radiation safety, and national arrangements for emergency preparedness and response. The agreed scope of the review covered all relevant facilities and activities regulated in Ireland and also included medical exposures and public exposure to radon. In advance of the mission, Ireland completed a process of self-assessment and review. This process identified strengths and weaknesses in the national regulatory framework compared with the international standards. In addition to the value of having Ireland’s radiation protection framework peer reviewed by senior international experts, the mission helped to further strengthen links between all the national bodies (government, licensees, regulatory) with a role in the regulation of radiation safety. The findings from the IRRS review team’s objective evaluation of Ireland’s regulatory infrastructure are being used to prioritise actions for strengthening the regulatory framework, to provide input into the transposition of the Euratom BSS, and to support the revision of the national emergency plan for nuclear accidents. It is planned to have addressed the findings of the IRRS mission in advance of a follow up mission in 2019. (author)
