Pre-Licensing Vendor Design Review

About

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

A pre-licensing vendor design review is an assessment of a nuclear power plant design based on a vendor's reactor technology. The assessment is completed by the CNSC, at the request of the vendor. 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 a new nuclear power plant.

This review 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.

The objective of a review is to verify, at a high level, the acceptability of a nuclear power plant design with respect to Canadian nuclear regulatory requirements and expectations, as well as Canadian codes and standards. These reviews also identify fundamental barriers to licensing a new design in Canada and assures that a resolution path exists for any design issues identified in the review.

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.

The reviews take place in three phases, each of which is conducted against related CNSC regulatory documents and Canadian codes & standards:

Phase 1: Pre-Licensing Assessment of Compliance with Regulatory Requirements: This phase involves an overall assessment of the vendor's nuclear power plant design against the most recent CNSC design requirements for new nuclear power plants in Canada as indicated in REGDOC 2.5.2, Design Of Reactor Facilities: Nuclear Power Plants or Design of Small Reactor Facilities (RD-367) as applicable, as well as all other related CNSC regulatory documents and Canadian codes & standards.

Phase 2: Pre-Licensing Assessment for Any Potential Fundamental Barriers to Licensing: This phase goes into further details with a focus on identifying any potential fundamental barriers to licensing the vendor's nuclear power plant design 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.

Status of Pre-licensing Vendor Design Reviews

Participating vendors and their review completion dates are outlined below. Please note that planned completion dates for current reviews may be adjusted as needed by mutual agreement.

Current pre-licensing vendor design reviews

On February 16, 2016, the CNSC agreed to conduct a phase 1 vendor design review for the Terrestrial Energy integral molten salt reactor design concept as described in guidance document GD-385, Pre-licensing Review of a Vendor's Reactor Design. The review duration is estimated to take 18 months as determined by Terrestrial Energy’s schedule for submissions. At the end of the review, an executive summary of the project report will posted on this Web page. For questions about the review, contact cnsc.information.ccsn@canada.ca.
