Pre-Licensing Vendor Design Review

A Pre-Licensing Vendor Design Review is an optional service provided by the CNSC when requested by a vendor.

This service does not certify a reactor design or involve the issuance of a licence under the Nuclear Safety and Control Act and it is not required as part of the licensing process for a new nuclear power plant. The conclusions of any design review do not bind or otherwise influence decisions made by the Commission.

A pre-licensing vendor design review is an assessment of a nuclear power plant design based on a vendor’s reactor technology. The words “pre-licensing” signifies that a design review is undertaken prior to the submission of a licence application to the CNSC by an applicant seeking to build and operate that design.

A vendor who has completed a phase 2 pre-licensing vendor design review, has committed to increased regulatory efficiencies at the time of licensing. The results of Phase 2 will be taken into account mainly for the Construction Licence Application and is likely to result in increased efficiencies of technical reviews.
