Cooperation in Pre-Licensing Review Activities for Advanced Reactors This activity serves as a platform for establishing and testing regulatory cooperation processes using specific case studies from a design under development, being reviewed in both Canada and the US.
CNSC and USNRC will each assess how the design is addressing regulatory requirements in each country and share experiences in a collaborative fashion.
Design: Terrestrial Energys Integral Molten Salt Reactor (IMSR)
Vendor engagement with regulators in U.S. and Canada: Terrestrial Energy USA is engaged in pre-application interactions with the NRC and submitted a white paper proposal to the NRC related to Postulated Initiating Events (PIE). CNSC is performing a Phase 2 Vendor Design Review with Terrestrial Energy Inc.
Key Activities and Outputs: CNSC and USNRC staff are developing a joint report concerning the identification and categorization of initiating events.
Design: X-energys Xe-100 Vendor engagement with regulators in U.S. and Canada:
X-energy is engaged in a combined Phase 1 and 2 Vendor Design Review with the CNSC and in pre-application interactions with USNRC. CNSC and NRC staff are currently reviewing a white paper from X-energy that outlines the regulatory and technical aspects of choosing a Construction Code for the Xe-100 RPV commensurate with its safety functions.
Key Activities and Outputs: CNSC and NRC are developing a joint report with observations on the white paper.
Sharing Regulatory Insights from the Technical Review of the NuScale SMR Design Certification Review Objective/Scope:
To share regulatory experiences and insights for the NuScale Power, LLC (NuScale) small modular reactor (SMR) design.
Vendor engagement with regulators in U.S. and Canada:
NRC approved a design certification for the NuScale SMR. NuScale is in the early phases of the combined phase 1&2 Vendor Design Review with the CNSC.
Key activities:
NRC and CNSC are exchanging information on key areas of the NuScale design.
Cooperation in Pre-application Review Activities Pertinent to Small Modular Reactors Design: GE Hitachis Small Modular Reactor BWRX-300 Vendor engagement with regulators in U.S. and Canada:
GEH has begun pre-application activities with USNRC and Combined Phase 1 and 2 Vendor Design Review project with CNSC.
Key Activities:
USNRC and CNSC plan to perform a collaborative review of the licensing topical report on the BWRX 300 Containment Evaluation Method and exchange information that will cover safety review methodologies, regulatory approaches, and treatment of unique aspects of the BWRX-300 Containment Evaluation Method.
A joint report will be prepared which is expected to summarize the findings of the CNSC and USNRC collaborative work that could be used in each regulators review process.
Develop Guidance for Staff Review of New Build License Applications for Advanced Reactor Projects Project: Develop Guidance for Staff Review of Applications for Advanced Reactor Projects Objective/Scope:
Develop common criteria/guidance for technology-inclusive, risk-informed, and performance-based staff review of applications for advanced reactors. Document areas of commonality and differences between the Canadian approach and US approach.
Key Activities and Outputs:
CNSC and USNRC staff are identifying the similarities and differences between their approaches to reviewing advanced reactor designs. Initial output will be a joint report comparing the USNRCs Licensing Modernization Project and Canadian practice.
