On 13-14 April 2017, the Generation IV International Forum (GIF) held its semi-annual Policy Group (PG) meeting in Paris, France, hosted by the NEA. Participants at this meeting included representatives from twelve GIF member countries, including the ten signatories of the GIF Framework Agreement and Australia, which joined the GIF in June 2016 and is currently in the process of acceding to the GIF Framework Agreement. The United Kingdom, one of the first countries to join GIF but currently a non-active member, was also represented at the meeting as an observer, and was encouraged by the PG to consider acceding to the GIF Framework Agreement. The PG also reviewed the progress in the development of safety design criteria and guidelines for the sodium-cooled fast reactor and their extension to other Generation IV systems, as well as laid the groundwork for the 4th GIF Symposium to be held on 16-17 October 2018. Deployment challenges for Generation IV systems in future energy markets and strengthening interaction with the private sector were also examined, building on the discussions with industry experts and professionals from large corporations and startups during the NEA workshop on "Advanced Reactor Systems and Future Energy Market Needs", which took place the previous day.
