ARC Clean Technology has reached a pivotal milestone with the completion of Phase 2 of the Canadian Nuclear Safety Commission (CNSC) Vendor Design Review (VDR) for its ARC-100 advanced small modular reactor. The CNSC’s report identified no fundamental barriers to licensing, a critical advancement for the reactor’s commercial deployment. The ARC-100, a 100MWe sodium-cooled fast neutron reactor, is designed for electricity production and industrial heat applications, utilizing proven technology to deliver clean, reliable power.
The Phase 2 VDR process, initiated in 2022, involved the submission of hundreds of technical documents across 19 focus areas by ARC. These documents covered safety systems, analyses, reactor and process system design, regulatory compliance, and quality assurance. Robert Braun, ARC’s Chief Operating Officer, emphasized the importance of this achievement, highlighting the CNSC’s international respect and the credibility it lends to the ARC-100 technology.
This development also supports ongoing licensing efforts for a demonstration unit of the ARC-100 in New Brunswick, where New Brunswick Power (NB Power) has submitted a license to prepare site application. Lori Clark, President and CEO of NB Power, commended ARC on this milestone, noting the collaborative effort in advancing innovative energy solutions.
With the successful completion of the CNSC review, ARC is now poised to move forward with further licensing and deployment steps, contributing to Canada’s leadership in clean energy and advanced nuclear technology. The ARC-100’s progress represents a significant step in the global transition to sustainable and reliable energy sources.
