Pre-Licensing Vendor Design Review –
takes plave in __ phases, conducted
against related ____ regulatory
documents and Canadian codes &
standards
the doc is ____

CNSC
REGDOC 2.5.2
Phase 1: Pre-Licensing Assessment of Compliance with Regulatory Requirements:
overall assessment of the vendor’s nuclear power plant design against the most recent CNSC design requirements for new nuclear power plants in Canada
3 phases are
Phase 1: Pre-Licensing Assessment of Compliance with Regulatory Requirements:
Phase 2: Pre-Licensing Assessment for Any
Potential Fundamental Barriers to Licensing
Phase 3: Follow-up
Phase 2: Pre-Licensing Assessment for Any
Potential Fundamental Barriers to Licensing
a focus on identifying any potential fundamental barriers to licensing in Canada
Phase 3: Follow-up
This phase allows the vendor to follow-up on certain aspects of Phase 2 findings by:
▪ seeking more information from the CNSC about a Phase 2 topic; and/or
▪ asking the CNSC to review activities taken by the vendor towards the reactor’s design readiness, following the completion of Phase 2.
