For more than twenty years now, the European Utility Requirements (EUR) organization has been actively developing and promoting harmonized technical specifications for the new designs to be proposed by the vendors in Europe. The EUR Document consists of a comprehensive set of requirements covering the whole Nuclear Power Plant (NPP). These terms of reference can be used by the utilities (guide for design assessment, technical reference for call for bids) and by the vendors (as a technical guide). The harmonization and standardization which is sought after by the EUR aims at delivering the safest and most competitive designs based on common rules shared all over Europe. Fifteen major nuclear operators across Europe are now members of the Organization. Over the last few years, the EUR organization has been extremely active. After the publication of the Revision D of the EUR Document (October 2012), the EUR organization released in March 2013 its roadmap for the period. This paper describes the main results obtained during that period of time and the new challenges in the three following fields. First, the revision of the EUR Document in order to maintain it at a state-of-the-art level remains the highest priority for the Organization. The paper presents the technical scope of the on-going new major revision (Revision E) which is scheduled to be issued in 2016. This project will deliver significant updates of the EUR document in many fields among which: revised Safety requirements taking into account lessons learned from the Fukushima accident and consistent with the most recent international safety standards, Instrumentation & Control, Seismic Approach, Probabilistic Safety Assessments. The assessment of new designs is the second main technical activity of the EUR organization. The MHI EU-APWR design has been assessed against the revision D between 2012 and 2014 and new design assessments applications have been received by the EUR organization (namely KEPCO's EU-APR1400 and AEP's VVER TOI). The paper briefly recalls the EUR design assessment objectives and process and the progress of the different assessment projects. The third topic to be covered by this paper is the interaction between the EUR and the other stakeholders, in particular the other international organizations (ENISS, WNA/CORDEL, WENRA, IAEA, EPRI). The paper describes how the EUR organization is connected to these stakeholders and the corresponding cooperation results and future projects.
