OPG resumes planning for new nuclear at DarlingtonNuclear NewsPower & OperationsNovember 25, 2020, 6:57AM|Nuclear News StaffDarlington nuclear power plant. Photo: OPGOntario Power Generation (OPG) recently announced the resumption of planning activities for future nuclear power generation at its Darlington site, with a goal of hosting a grid-size small modular reactor as soon as 2028. Originally, plans for the Darlington new nuclear project were focused on the construction of traditional large reactors.Located in Clarington, Ontario, Darlington is the only site in Canada currently licensed for new nuclear. OPG was granted a license from the Canadian Nuclear Safety Commission (CNSC) in 2012 to allow site preparation activities for the project. The company has applied to renew the license, which is set to expire in August 2022. The CNSC will hold a public hearing on June 9–10, 2021, to consider the license renewal.Early last month, OPG announced that it was working with three grid-scale SMR technology developers—GE Hitachi, Terrestrial Energy, and X-energy—to advance engineering and design work, with the goal of identifying options for future deployment.Benefits: A study undertaken by the Conference Board of Canada showed a strong economic boost to Ontario from the construction and 60 years of operation of a single reactor in the province, according to OPG on November 13. Direct, indirect, and spin-off related employment, the study said, would result in an annual average of approximately 700 jobs during project development, 1,600 jobs during manufacturing and construction, 200 jobs during operations, and 160 jobs during decommissioning.In addition, the study found that the project would have a positive impact on direct, indirect, and induced gross domestic product of more than $2.5 billion and would result in an increase of provincial revenues of more than $870 million.The next generation: “OPG is paving the way on the development and deployment of the next generation of nuclear power in Canada,” said Ken Hartwick, OPG’s president and chief executive officer. “A new SMR development on this site as early as 2028 would benefit all Ontarians while further cementing Durham Region and Ontario as the clean energy capital of the world.”Greg Rickford, Canada’s minister of energy, mines, northern development, and indigenous affairs, said, “Our government is proud to support OPG’s efforts to develop cutting-edge SMR technology right here in Durham at the Darlington nuclear station by the end of this decade. Ontario and our provincial partners in Saskatchewan, New Brunswick, and Alberta are leading the charge on SMR deployment in Canada and showcasing our nuclear expertise and made-in-Ontario technology to the world.”Tags:canadian nuclear safety commissiondarlingtonge hitachiontario power generationsmall modular reactorterrestrial energyx-energyShare:LinkedInTwitterFacebook

Image: GE Hitachi NuclearThe Nuclear Regulatory Commission has issued a final safety evaluation report for the first of several licensing topical reports (LTR) submitted by GE Hitachi Nuclear Energy (GEH) for the BWRX-300 small modular reactor, the company announced on December 1.The initial LTR, titled “BWRX-300 Reactor Pressure Vessel Isolation and Overpressure Protection,” was submitted to the NRC in December 2019, officially beginning the U.S. licensing process. This LTR forms the basis for the “dramatic simplification” of the BWRX-300, according to GEH.In its announcement, GEH noted that two additional LTRs were submitted in early 2020 and that it anticipates reviews of those reports to be completed in the coming months. A fourth LTR was submitted in September 2020, the company added.Go to Article
NuScale unveils Energy Exploration Center at Oregon StateNuScale Energy Exploration Center at Oregon State University. Photo: Business WireSmall modular reactor developer NuScale Power has announced the opening of the NuScale Energy Exploration (E2) Center at Oregon State University (OSU).The E2 Center is designed to offer users a hands-on learning opportunity to apply nuclear science and engineering principles through simulated, real-world nuclear power plant operation scenarios, according to NuScale on November 17. The center employs state-of-the-art computer modeling within a simulator of the NuScale SMR power plant control room, allowing users to take on the role of control room operator at a 12-unit NuScale SMR plant to learn about the features and functionality unique to the company’s SMR technology.More to come: The E2 Center at OSU is the first of three planned installations of a NuScale power plant control room simulator at U.S. universities. Support for the centers was provided by a grant in 2019 from the Department of Energy. Additional information on the E2 Center is available here.Go to Article
Testing for Terrestrial Energy’s IMSR under way with research partnersTerrestrial Energy and the Nuclear Research and Consultancy Group (NRG) have started a graphite irradiation testing program at NRG’s Petten Research Centre’s High Flux Reactor (HFR), located in the Netherlands. According to Terrestrial Energy, which is based in Ontario, Canada, the work is part of broader program of confirmatory testing of components and systems for the company’s Integral Molten Salt Reactor (IMSR), designed to produce both electricity and industrial heat.The testing program at NRG was planned to confirm the predicted performance of selected graphite grades throughout the seven-year cycle of an IMSR core. The testing was designed in cooperation with Frazer-Nash Consultancy, and will simulate IMSR core conditions at a range of operating temperatures and neutron flux conditions.“Our work with NRG at its Petten HFR facility is an important element of our overall IMSR test program, now well underway. The start of in-core irradiation tests speaks to our progress and comes after many months of prior work,” Simon Irish, CEO of Terrestrial Energy, said on November 12. “The NRG work also reflects an important feature of our testing strategy. That is to engage existing laboratories offering existing capabilities rather than build those in-house, a strategy that is essential for our early deployment schedule.”Go to Article
