European Utility Requirements for advanced LWR issue of EUR revision E and ongoing activities

Since 1991, the European Utility Requirements (EUR), Organization has been actively developing and promoting harmonized technical specifications for advanced LWR designs in Europe gathered into a unique EUR Document. Currently fourteen nuclear European operators are members of the EUR Organization. The EUR Document consists of a comprehensive set of requirements covering the whole aspects of the design of a new nuclear power plant (NPP), encompassing safety, performance and competitiveness for the main parts of a NPP (nuclear and conventional islands). The EUR Document can be used by Utilities and by Vendors as a technical guide or by other stakeholders as a synthesis of the European utilities harmonized positions. The harmonization which is sought after by the EUR organization aims at delivering the safest and most competitive GEN III NPP designs based on common rules. Revision E of the EUR Document completed in December 2016, is now available for distribution and use by the different stakeholders. The presentation will describe the most significant updates implemented, such as revised safety requirements taking into account the most recent European and International safety standards issued by WENRA and IAEA, the Fukushima lessons learned, including re-evaluated seismic and other external natural hazards approach and the most recent international technical standards and best practices. After this important milestone, the EUR organization has defined new challenges for the three coming years through the 2019-2021 roadmap which will be stated in the presentation. The first one is to develop new Position Papers and harmonized requirements representing up-to-date European Utilities positions related to new LWR projects, especially innovative designs such as Small Modular LWR (SMLWR). The second topic is related to new design assessments against EUR. The presentation will briefly recall the assessment process and will describe the schedule of the assessments in progress (Russian AEP's VVER TOI and Chinese CGN's EU-HPR 1000). The EU-HPR1000 is the first design to be assessed against the EUR revision E Document. The third future activity deals with the promotion of the EUR Organization voice by developing efficient interactions with stakeholders (regulators, vendors, ENISS, IAEA, WNA/CORDEL,...) and by proposing new utilities to join the EUR Organization, as EUR member for European utilities having nuclear program development or in a newly created status of EUR Observer member for non European utilities that would seek to promote the same objectives as the EUR Organization.
