ONTARIO POWER GENERATION INTENDS TO CONSTRUCT 4 BWRX-300 REACTORS AT DARLINGTON NUCLEAR GENERATING STATION
|
April 2023 - CNSC announced that it will conduct a public hearing on applicability of the Darlington New Nuclear Project environmental assessment and plant parameter envelope to selected reactor technology (the same topics were the subject of comments to CNSC staff in March 2023).
The Canadian Nuclear Safety Commission (CNSC) will hold 2 separate public hearings to consider the application from Ontario Power Generation (OPG) for a licence to construct a reactor facility for its Darlington New Nuclear Project (DNNP). The first hearing will be held during the week of January 22, 2024 and will focus on the applicability of the DNNP environmental assessment (EA) to Ontario Power Generation’s selected reactor technology. The second hearing is currently expected to be held in late 2024. OPG’s hearing submission and CNSC staff’s recommendations to be considered at the hearing will be available on the CNSC website, or on request to the Commission Registry, after September 18, 2023 For other OPG documents related to the project, please see supporting documents and resources. |
NEXT DEADLINE: COMMENT ON EIS REVIEW AND PPE BY NOVEMBER 20th; COMMISSION HEARING ON JANUARY 22, 2024. Details HERE
Key Documents (as of June 2023)

December 2022 - The Canadian Nuclear Safety Commission (CNSC) solicited feedback on two documents (OPG's Updated Plant Parameter Envelope Report and Environmental Impact Statement Review Report) "from individuals, interested groups, and Indigenous Nations and communities. Comments were accepted on these documents until March 20, 2023 and will remain posted thereafter. The CNSC will not respond to comments during this phase of the licensing process; however, the comments will inform CNSC staff’s technical review of the documents."

Ontario Power Generation has Submitted their Application to Construct the BWRX-300 at Darlington
On October 31, 2022, OPG has submitted an application for a Licence to Construct to the Canadian Nuclear Safety Commission (CNSC). This licence application is the next step in the deployment of a Small Modular Reactor (SMR) at the Darlington site. The application was developed collaboratively between OPG and GE Hitachi, and is comprised of a number of information packages that will be submitted to the CNSC in sequence, over the next six months. The CNSC has announced a deadline of December 2nd to apply for participant funding to support the review of 2 Ontario Power Generation (OPG) documents: Use of Plant Parameters Envelope to Encompass the Reactor Designs being Considered for the Darlington Site and Darlington New Nuclear Project Environmental Impact Statement Review Report for Small Modular Reactor BWRX-300.
OPG Announces Selection of GE Hitachi's BWRX-300 SMR for Darlington
2 December 2021 - Ontario Power Generation has selected GE Hitachi's BWRX-300 reactor for construction of up to four "small modular" reactors at the Darlington Nuclear site. GE-Hitachi's BWRX-300e reactor is a 300 MW boiling water reactor that will use 3.4 to 4.95% enriched uranium for fuel. OPG. According to OPG, site preparation will begin in the spring of 2022, pending appropriate approvals, OPG said they aim to apply to the Canadian Nuclear Safety Commission (CNSC) for a construction licence by the end of next year, and could be completed by the end of 2028.

In September 2020, the International Atomic Energy Agency produced the report ADVANCES IN SMALL MODULAR REACTOR TECHNOLOGY DEVELOPMENTS 2020 Edition. This 354 page report provides 3-4 page summaries of over 70 designs, including all those listed in the two tables on this page. Read the four page exerpt about the BWRX-300 HERE

The Canadian Nuclear Safety Commission has a "Pre-Licensing Vendor Design Review (VDR) " service it offers to prospective reactor vendors. GE-Hitachi Nuclear Energy's BWRX-300 reactor is in a Phase 2 review, which commenced in January 2020. Phase 2 reviews are estimated to take two years. A Phase 1 review was not undertaken; with an asterick, the CNSC web site notes that "*Phase 1 objectives will be addressed within the Phase 2 scope of work." There is no report available of CNSC's review or observations to date, and no access provided to the documentation that GE-Hitachi has provided. See the CNSC web page HERE

Additional Notes
- The GEH BWR fuel assemblies are about 4.5 m long, and weigh about 300 kg. In comparison, CANDU fuel bundles weigh less than 24 kg and are half a metre long . The burnup range of CANDU fuel is about 120-320 MWh/kg U, with a mean burnup value of 200-220 MWh/kg U. At this burnup, about 2% of the initial uranium has been “burned” and converted into other atoms. GEH BWR fuel is designed for higher burnup of about 1200 MWh/kg U. [Source: NWMO-TR-2022-14, March 2022] In summary: BWR fuel assemblies are 9 times longer and 10 times heavier than a CANDU fuel bundle.
