Mascari, A. Schaffrath, I. Tiselj, E. Uspuras, Y. Yamamoto, D. Gumenyuk, N. Fedotova, O. Cronvall and P. Liska 1 Introduction In October 2011, ETSON published the “Position Paper of the Technical Safety Organizations: Research Needs in Nuclear Safety for Gen 2 and Gen 3 NPPs” [1]. This paper, published only a few months after the Fukushima-Daiichi severe accidents in Japan, presented the R&D priorities on the main pending safety issues. It was produced by the ETSON Research Group (ERG) that has the mandate of identifying and prioritizing safety research needs, sharing information on research projects in which ETSON members are involved, defining and launching new research projects and disseminating knowledge among ETSON members. Six years after the above publication, many R&D international projects in frames such as OECD/NEA/CSNI and Euratom have finished and others have started. In particular a lot of work was done (and is going on…) on the analysis of the Fukushima-Daiichi severe accidents. Meanwhile a roadmap on research on Gen.II and III nuclear power plants (NPP), including safety aspects, was elaborated by the NUGENIA association and published in 2013 [2], followed in April 2015 by a more detailed document as “NUGENIA global vision” [3]. Thus in 2016-2017, the ERG judged it necessary to perform an update of the ETSON ranking of R&D priorities, accounting for recent outcomes of research projects (and, for severe accidents, knowledge gained on the Fukushima- Daiichi accidents) and for the NUGENIA R&D roadmaps. The main objective was to underline a possible convergence of topics for further R&D, but accounting for current international R&D projects to avoid duplication of efforts. 2 Process of ranking of priorities Thirteen ETSON members participated to the exercise focusing on the safety aspects with the challenge to agree on a short list of high priority topics and avoid the topics where significant R&D is ongoing. A good example of the latter case is In-Vessel-Melt-Retention during a severe accident where many organizations from Europe (and beyond) participate in the IVMR H2020 project [4]. For the sake of simplification, the process was based on the list of R&D challenges and issues from the NUGENIA roadmap (each challenge includes several specific issues). The partners were asked to: • Select up to 10 highest-priority challenges: give the mark 1 for the most important,…, 10 for the less important, • Then, for each of them, select up to 3 issues: give the mark 1 for the most important..., 3 for the less important. The ranking process was based on the list of R&D highpriority issues (around 150) from the latest NUGENIA R&D roadmap. This list covers the 6 following topical areas: plant safety and risk assessment, severe accidents, improved reactor operation, integrity assessment of systems, structures and components, fuel development, waste and spent fuel management and decommissioning, innovative LWR design and technology. The results indicated a rather large scattering of votes on issues but also the possibility of identifying issues with a majority of votes. The average ranking was the sum of marks divided by number of votes. The combined ranking of challenges and issues was then obtained as “challenge average ranking” multiplied by the “issue average ranking”. The smallest figures have the highest priority. Eight issues, described in the Section 3, were selected as the highest priority (the order of presentation does not represent a decreasing order of priority, the issues are in the order of the NUGENIA roadmap). This Section summarizes the importance of the issue for safety, the state of knowledge and the remaining gaps, and the international context such as ongoing or starting R&D projects. 3 High priority issues 3.1 Improved thermal-hydraulics evaluation for the existing plants Most of the thermal-hydraulic phenomena during accidents in NPPs occur at the scale of NPP cooling systems (thermal-hydraulics in Spent Fuel Pools or SFP is addressed in § 3.5). The NPP response often represents a complex interplay of the processes and phenomena in the subsystems, which can be reproduced or analyzed only with an experimental facility with a similar complexity or with a simulation system code that contains models of all relevant subsystems. Large integral facilities and system codes thus represent a basis for NPP safety analyses. More or less an integral facility was built in the past (or is being built) to correspond to every major NPP type, and thus was (or is) used to examine the plant performance during safety relevant scenarios. Such review of integral facilities and experiments was prepared by OECD/NEA/CSNI [5]. Some of these facilities have already been dismantled, some of them are maintained (PKL in Germany, as well as INKA for Gen.3+ BWR safety systems, and LSTF in Japan), while the countries with long term nuclear goals upgrade (MOTEL in Finland) or build entirely new (ACME in China) facilities. These experiments were and are still used for validation and verification of system codes (CATHARE, ATHLET, TRACE, RELAP ...) that represent indispensable tools for safety analyses. A complementary approach to the integral thermalhydraulics testing is the “bottom-up” approach, which actually means experimental and numerical studies of separate effects at larger scales under well-defined initial and boundary conditions. These test facilities are more accessible for academic institutions and can be roughly divided into problems of single-phase and two(multi)- phase flow phenomena. Single-phase experiments and computational fluid dynamics (CFD) can be considered a mature research field, where even blind predictions of rather complex flows with heat transfer (pressurized thermal shock, natural convection) and mixing of species atw-Special „Eurosafe 2017“.
