مبادرة الوكالة لتيسير نشر المفاعلات النمطية الصغيرة تنتقل إلى مرحلة التنفيذ

“The global deployment of SMRs will need a degree of regulatory convergence,” added Mr Grossi. “We’re not aiming at unison, as it’s impossible, but without some degrees of concrete collaboration where we can leverage what others are doing, the business model of modularity and flexibility is simply not going to work.”  

Aline des Cloizeaux, Director, Division of Nuclear Power of the IAEA, explained the vision of the project is to “to make nuclear simpler while keeping it safe and secure”. 

She added: “We are paving the way for SMR projects that are faster, simpler and more economical to deploy.”  

The industry track of NHSI has had more than 200 contributors from over 30 countries and has worked in four main areas of harmonization, including end user requirements, and collaboration on computer codes for monitoring the safety and performance of advanced nuclear reactors (NEXSHARE). 

The short-term goals are to map pathways and reduce timelines and costs to both vendors and customers; to facilitate common approaches for regulatory approvals; and to gather lessons learned from SMR deployment models – with the long-term goal of preparing industry, end-users and countries for large-scale SMR deployment. 

Anna Hajduk Bradford, Director of the IAEA’s Division of Nuclear Installation Safety, explained the goals of the second track of the initiative. “The long-term aspiration of the NHSI regulatory track is the development of a global framework for regulatory reviews of advanced reactors. This is an ambitious goal.” 

Steps towards that goal include building a high level of trust among regulatory bodies and an understanding of commonalities and differences among regulatory frameworks in different countries.  

NHSI has been working closely with national regulators while “always ensuring the member states’ keep their own sovereignty and decision making,” Bradford added. 

“In addition, we envisage the establishment of a dedicated working group on nuclear security of SMRs, which will serve as another important resource for Member States.” 

Dozens of countries also gave their thoughts on NHSI’s progress so far and plans for the future. There was widespread agreement on the value of the work done in the first phase, and the direction planned for the second phase, with many topics raised for ongoing consideration. 

Christer Viktorsson, Director General, Federal Authority For Nuclear Regulation (FANR), United Arab Emirates said: “It is clear this initiative is having an effect, it is already creating momentum for working towards harmonization and standardization. It’s clear that Phase II should focus on the implementation of projects from Phase I.” 

Paul Fyfe from the United Kingdom’s Office For Nuclear Regulation (ONR) agreed: “Cooperation and collaboration between industry and regulators is key. The UK ONR strongly supports Phase II. There’s a real need for this work to be done.” 

Marcus Nichol Executive Director for New Nuclear from the United States’ Nuclear Energy Institute agreed: “We share your visions that you articulated for both the industry track and to facilitate the regulatory frameworks and reduce unnecessary design changes, so we appreciate that. All of the proposals for Phase II are on the right track, all of those areas will be valuable.” 

Representatives from regulators and industry spoke on a range of other questions relating to safeguards; safety and security issues; information sharing with newcomer countries; confidentiality; avoiding duplication of work; collaboration between regulators, designers and operators; choosing the best priorities; and ensuring technical experts are consulted. 

NHSI is now moving to the next phase, which will be to implement many of the recommendations the working groups have come up with.  

Phase II will also focus on providing tools to help understand regulatory commonalities and differences better, it will examine technology-specific user requirements and explore what is needed to facilitate the approval of what is known as long-lead items.
