NEA Nuclear Safety Research Joint Projects Week: Success Stories and Opportunities for Future Developments

Since its inception, the NEA has provided a highly flexible and powerful platform for multinational research co-operation, particularly in areas related to providing understanding and insights needed to improve global nuclear safety. For decades, the projects conducted under NEA's auspices have enabled nuclear safety regulators, industry and research organisations from NEA member countries, as well as from non-NEA member countries, to share research costs and results, results which have informed safety regulations, practices and facilitated safety harmonisation around the world.


The NEA Nuclear Safety Research Joint Projects Week was established to recognise the many accomplishments achieved by the international community in the course of these projects over the last four decades. High-level panels and a series of technical sessions reviewed the main benefits of NEA safety research joint projects and discussed how the established framework, research platforms and networks could support future developments in the nuclear energy sector, thereby facilitating innovation and greater harmonisation.

This workshop brought together stakeholders from the nuclear energy sector, including regulators, representatives from technical support, research and international organisations, as well as industry representatives to share views on research frameworks, platforms and competences needed in order to maintain or develop future collective nuclear safety research in the nuclear energy sector. Based on the experience gained through NEA safety research joint projects, workshop participants also shared recommendations for the development of future collaborative international research ventures at the NEA to support innovation.

Workshop objectives

The objective of this workshop was to review the experience gained in the last 40 years of NEA nuclear safety research joint projects with close to fifty projects successfully completed. Event participants discussed the benefits of the development of technical bases for the demonstration of safety and reflected on how safety research joint projects contributed to shaping the collective intelligence that connects the industry, regulators and research organisations on key safety aspects. Participants also exchanged on how to preserve key research facilities and key competences currently at risk that contribute to the education of young researchers, as well as the production of high quality data sets for safety codes development and validation; most of these data sets being available to NEA member countries through the NEA Data Bank.

The event also provided a forum to discuss maintenance and evolution of the established frameworks, research platforms and networks to open up opportunities for supporting the continued safe operation of nuclear power plants and to ease the licensing process of new reactor designs and systems, including small modular reactors (SMRs) and innovative safety systems. In particular, different technology developers, technical and scientific support organisations (TSOs) and experimental researchers operating research facilities discussed areas for co-operation and resource sharing for experiments, code validation activities and related competences.


The workshop was organised in three main streams:

  • During the first day participants took stock of the existing overall experience and discussed the main benefits of NEA joint projects, as well as opportunities for evolution of the joint projects framework and infrastructures.
  • The following three days were devoted to reviewing concrete examples of joint projects in safety in design, in operation, and in accidents addressing technical fields such as accident analysis and management, fuel safety, safety of systems, structures and components including reliability of innovative design safety solutions, etc., highlighting successful aspects, lessons learnt, as well as current and future challenges.
  • The last day focused on summarising the discussions from the first four days and providing recommendations for future research initiatives.
Challenges addressed

The workshop addressed the following challenges:

  • Challenge 1 – How safety research joint projects could best ensure safety research is carried out in an efficient and effective manner for the benefit of all stakeholders of the nuclear energy sector, given their future expectations for both conventional and a variety of innovative technologies?
  • Challenge 2 – How safety research joint projects could better serve development and maintenance of key competences and research infrastructures, including the education of new talent for the future of the nuclear energy sector?
  • Challenge 3 – What should be the new approaches and arguments for facilitating decisions from public and private stakeholders of the nuclear energy sector to fund the future safety research joint projects for the benefit of nuclear innovation and safety in general?
  • Challenge 4 – What mechanisms should be set to establish future priorities for international co-operation in nuclear safety research?



Recommendations and proposals for enhancing the efficiency and benefits of projects for the nuclear sector were put forward in five main directions (read the "Summary and Main Outcomes of the NEA Nuclear Safety Research Joint Projects Week: Success Stories and Opportunities for Future Developments" for more details):

  • to establish additional mechanisms and advisory panels at appropriate levels to prioritise needs in nuclear safety research, including for advanced concepts, and support the development of targeted project proposals;
  • to promote more integrated approach of safety research in main safety technical areas (e.g. accident and ageing management), around sets of experimental platforms;
  • to promote industry involvement, including designers of advanced concepts, by including further their needs;
  • to secure projects’ outcomes preservation and dissemination for expertise building and wider use, including in countries with recent nuclear power development;
  • to implement mechanisms within projects for enlarging expertise building.

The NEA, with the support of its technical committees, will propose concrete actions to progress in these directions and to continue with projects that bring benefits to the nuclear sector.
