The Canadian Nuclear Safety Commission (CNSC) has finished Phase 3 of the Pre-Project Design Review of Atomic Energy of Canada Ltd.’s (AECL) Advanced Candu Reactor (ACR-1000), making it the first advanced nuclear power reactor to have completed three phases of a vendor pre-project design review by the CNSC.

As a result of the third and final phase of the CNSC Vendor Pre-Project Design Review, the ACR-1000 meets Canada’s nuclear regulator’s expectations for new nuclear power plants in Canada. The CNSC findings indicate there are no fundamental barriers to licensing the reactor design in Canada.

The objective of a Vendor Pre-Project Design Review is to verify, at a high level, the acceptability of a nuclear reactor design with respect to Canadian safety requirements and expectations. To achieve this objective, CNSC staff assessed specific safety and security aspects of the ACR-1000 design to identify any potential technical issues that could constitute a potential fundamental barrier to licensing a new reactor design in Canada.

In Phase 3, AECL requested that the CNSC review some specific aspects of Phase 2 findings for eleven review topics. CNSC assessed activities undertaken under these topics to further determine the readiness of the reactor design for licensing.
