Update on the CNSc's SMR Discussion Paper

Abstract

To keep current on technology trends and regulatory implications, many nuclear regulators, including the CNSC, have been reviewing the application of novel features in more traditional, and larger, NPP designs. SMRs, however, represent novel technologies that aim to achieve greater efficiencies and reduced operational costs. One of the key questions that nuclear regulators – including the CNSC – must address with vendors and other stakeholders is what are the regulatory and licensing implications presented by SMRs? If a proponent decides to deploy such technologies in Canada, what are some of the key regulatory issues that need to be resolved in advance to meet Canadian licensing requirements?

As a result of the CNSC's examination, a discussion paper DIS-16-04, Small Modular Reactors: Regulatory Strategy, Approaches and Challenges was published on May 31, 2016 and is open for comments until September 28, 2016. The discussion paper provides an overview of potential regulatory issues associated with SMRs and how they could be addressed.

This paper provides an overview of the feedback received on this discussion paper and outlines how the CNSC will use the feedback received to bring greater clarity to its regulatory framework for SMRs.
