GEH submits BWRX-300 SMR design for Canadian review

10 March 2020

GE Hitachi Nuclear Energy (GEH) has made its first submittals to the Canadian Nuclear Safety Commission (CNSC) for the vendor design review (VDR) of its BWRX-300 small modular reactor. The submittals are for the combined first two phases of the three-phase process and address eight of the 19 VDR focus areas. 

The VDR is an optional service provided by the CNSC to provide an assessment of a nuclear power plant design based on a vendor's reactor technology. It aims to verify the acceptability of a design with respect to Canadian nuclear regulatory requirements and expectations, providing early feedback during the design process.

The BWRX-300 is a 300 MWe water-cooled, natural circulation SMR with passive safety systems. It leverages the design and licensing basis of GEH's ESBWR boiling water reactor, which has been certified by the US Nuclear Regulatory Commission.

By leveraging the existing design certification of the ESBWR, using licensed and proven nuclear fuel design, incorporating proven components and supply chains and implementing simplification innovations, GEH said it believes the design can become cost-competitive with generation from combined cycle gas plants and renewable energy platforms.
