NUCLEAR SAFETY RESEARCH JOINT PROJECTSWEEK: SUCCESS STORIES AND OPPORTUNITIESFOR FUTURE DEVELOPMENTS
9-13 January 2023, 13:00-16:00 CET, Zoom Webinar(This online workshop takes place in three-hour slots each day
to allow full international participation.)
Since its inception, the NEA has provided a highly flexible and powerful platform for
multinational research co-operation, particularly in areas related to providing
understandings and insights needed to improve global nuclear safety. For decades,
the projects conducted under NEA auspices have enabled nuclear safety regulatorsand industry from NEA member countries – as well as partners that are not membersof the NEA – the ability to share research costs and results that have informed
regulations and practices around the world and facilitated the harmonisation of
nuclear safety rules and practices around the world.
The NEA Nuclear Safety Research Joint Projects Week has been established torecognise the many accomplishments achieved by the international community in thecourse of these projects over the last four decades. High-level panels and a series oftechnical sessions will review the main benefits of NEA safety research joint projects
and discuss 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 brings together stakeholders from the nuclear energy sector, including
regulators, representatives from technical support, research and internationalorganisations, as well as industry representatives to share views on researchframeworks, platforms and competences needed in order to maintain or develop futurecollective nuclear safety research in the nuclear energy sector. Based on the experience
gained through NEA safety research joint projects, workshop participants will also share
recommendations for the development of future collaborative international research
ventures at the NEA to support innovation.

Workshop objectives
The objective of this workshop is to review the experience gained in the last 40 yearsof NEA nuclear safety research joint projects. Event participants will discuss thebenefits of the development of technical bases for the demonstration of safety andreflect on how safety research joint projects contribute to shaping the collective
intelligence that connects the industry, regulators and research organisations on key
safety aspects. Participants will also exchange on how to preserve key researchfacilities and key competences currently at risk that contribute to the education ofyoung researchers, as well as the production of high quality data sets for safety codesdevelopment and validation; most of these data sets are available to NEA member
countries through the NEA Data Bank.

The event will also provide a forum to discuss maintenance and evolution of theestablished frameworks, research platforms and networks to open up opportunities forsupporting the continued safe operation of nuclear power plants and to ease thelicensing 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 will discuss areas for co-operation and resource sharing forexperiments, code validation activities and related competences.

Structure
The workshop is organised in three main streams:•

During the first day participants will take stock of the existing overall experienceand discuss the main benefits of NEA joint projects, as well as opportunities forevolution of the joint projects framework and infrastructures.

•

The following three days will be devoted to reviewing concrete examples ofjoint projects in safety in design, in operation, and in accidents addressing
technical fields such as accident analysis and management, fuel safety, safetyof 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 will focus on summarising the discussions from the first four days
and providing recommendations for future research initiatives.

Challenges addressed
The workshop will address 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 forfacilitating decisions from public and private stakeholders of the nuclear
energy sector to fund the future safety research joint projects for the benefitof 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?
