The ongoing Brexit negotiations, including matters relating to the UK's decision to leave the EURATOM Treaty, are being conducted bilaterally between the European Union, represented by the European Commission, and the UK. Ireland contributes to the process through its representation at the European Council Article 50 Working Party which meets regularly to discuss Brexit related issues, including EURATOM.
While I have not had correspondence or discussions directly with my UK counterpart regarding the UK's decision to exit from the EURATOM Community, officials from my Department continue to engage on this, and other related matters, with their UK counterparts through the UK-Ireland Contact Group on Radiological Matters. The Group met most recently on 10 October, 2017 and that meeting included a briefing from the UK on measures being developed to ensure that the UK meets its obligations under international conventions on nuclear safety post-Brexit.
