Abstract [eng] The European Technical Safety Organizations Network (ETSON) is an association of Technical Safety Organizations (TSO), whose main goal and duty is to provide technical expert support to national Authorities in Nuclear Safety and Radiation Protection. Research is fundamental not only to develop and maintain a high level of technical expertise necessary for TSO expert safety assessment, but also to support the whole international research community to achieve safety objectives, in the context of IAEA, OECD or European platforms such as NUGENIA. Moreover, the TSOs’ needs for advanced R&D contribute to orienting research in this field and establishing priorities. This helps to concentrate the resources available for research, with focus on topics which are relevant for most countries and avoiding duplication of efforts. The ETSON Research Group (ERG) aims to identify the needs for nuclear reactor safety research for Gen.II-III Nuclear Power Plants (NPP), ranking their priorities, sharing information on R&D projects/activities in which ETSON members are involved, and launching initiatives for new R&D projects. The ETSON members address most technical domains relevant for safety by national and international R&D projects and collaborations. In these domains, they have set up experienced experimental and modelling teams, built experimental research facilities, developed simulation codes and performed their verification and validation. These domains are principally: thermal hydraulics; material testing reactors and fuel behaviour; reactor physics and criticality; materials, mechanics, chemistry and corrosion; severe accidents, emergency preparedness and response; uncertainty methods and probabilistic safety assessment; hot laboratories with irradiated materials and research reactors; and fires and explosion. They also work on waste disposal, but these activities are not described in this paper. For each of the above domains, a few illustrations of ETSON experimental facilities and simulation codes, with their scope of applicability, will be briefly described. For modelling, the focus will be on the code developers’ teams, mainly for large or unique codes, and a list of most widely used codes will be given. On facilities, the focus will be made on the large or unique facilities. The possibility of the modelling and experimental teams receiving students and/or researchers through mobility within ETSON is highlighted. This emphasizes that, as a whole, ETSON covers all safety issues with experienced teams and capabilities and can address further R&D challenges such as new materials, fuels, and safety systems.
