Ontario Power Generation has announced that refurbishment of Unit 3 at its Darlington nuclear plant is progressing ahead of schedule, with an expected return to service by late 2023, rather than early 2024.

As part of its “Made in Ontario” strategy announced last year, Bruce Power has awarded a contract valued at C$130 million (about US$100.8 million) to BWXT Canada in support of the ongoing major component replacement (MCR) project at the utility’s eight-unit Bruce nuclear plant.

The Canadian Nuclear Safety Commission has renewed the operating license of the reactor at the Point Lepreau nuclear plant for a period of 10 years. As a result, the facility’s 660-MWe CANDU-6 unit, the five-year license for which was set to expire on June 30, is now permitted to operate until the end of June 2032. License holder NB Power had requested an unprecedented 25-year extension.

The Advanced Test Reactor (ATR) at Idaho National Laboratory will soon be irradiating fuel pellets containing thorium and high-assay low-enriched uranium (HALEU) developed by Clean Core Thorium Energy for use in pressurized heavy water reactors (PHWRs). Clean Core announced on June 14 that it will proceed with irradiation testing and qualification under an agreement with the Department of Energy; the plans have been in the works since at least 2020, when the DOE filed a National Environmental Policy Act (NEPA) disclosure for the work.

SNC-Lavalin and Moltex Energy are partnering to advance the development and deployment of small modular reactor technology in Canada, the companies announced last week at the Canadian Nuclear Association’s 2022 conference in Ottawa, Ontario. The partnership will support Moltex as it pursues the licensing and construction of its 300-MW Stable Salt Reactor–Wasteburner (SSR-W), a molten salt reactor that uses nuclear waste as fuel.

Bruce Power and Ontario Power Generation (OPG) have announced an agreement to work together to support new nuclear technologies in Ontario. Bruce Power operates the Bruce nuclear plant and OPG operates the Darlington and Pickering facilities.

Ontario Power Generation has passed the midway point in its C$12.8 billion (about $10 billion) Darlington nuclear plant refurbishment project with the start of work on Unit 1, the company has announced. The unit is expected to be ready for grid reconnection in the second quarter of 2025.

Darlington houses four 878-MWe CANDU pressurized heavy water reactors, all of which entered commercial operation in the early 1990s. The plant is located in Clarington, Ontario, Canada.

The International Energy Agency’s newly published in-depth review of Canada’s energy policies, the first since 2015, urges the nation’s government to take more action in support of nuclear energy.

The 261-page report, Canada 2022 Energy Policy Review, released on January 13, features a 17-page section devoted to nuclear that includes four specific recommendations for Canada’s federal government:

Ontario Power Generation (OPG) has selected GE Hitachi Nuclear Energy (GEH) as its technology partner for the Darlington nuclear new-build project. The companies will work to deploy GEH’s BWRX-300 small modular reactor at OPG’s Darlington nuclear plant, located in Clarington, Ontario.

Canadian Nuclear Laboratories (CNL) and Korea Hydro and Nuclear Power (KHNP) intend to leverage data collected over decades on the dry storage of spent nuclear fuel to help inform decision-making on future spent fuel storage, transportation, and disposal activities.

The Canadian Nuclear Safety Commission has approved the renewal of the site preparation license for Ontario Power Generation’s Darlington new-build nuclear project. First granted in 2012, the license is now valid until October 11, 2031.

The first of eight 160-ton steam generators for Unit 6 at Canada’s Bruce nuclear power plant was installed last week as part of the facility’s major component replacement project. “Congrats to the MCR team and our partners, including @AeconGroup, @Framatome_CA, @UEandC, @mammoetglobal, @BWXT, and others who contributed to this historic moment,” Bruce Power tweeted on September 30.

The component was fabricated at BWXT Canada’s Cambridge, Ontario, location and was shipped to the Bruce site in late 2020, as shown in this video.

The vendor responsible for generator removal is the Steam Generator Replacement Team (SGRT), a 50-50 joint venture between Aecon and the Steam Generating Team, itself a partnership between Framatome and United Engineers & Constructors. In July, Framatome announced that SGRT had been awarded an approximately C$350 million (about $278 million) contract by Bruce Power to replace the steam generators at Units 3 and 4.

Natural Resources Canada, a department of the Canadian government, and Romania’s energy ministry have signed a memorandum of understanding to strengthen cooperation in the civil nuclear realm, including collaboration on CANDU refurbishments and new-build projects in Romania.

A delegation from the Department of Energy arrived in Romania in late July to discuss bilateral energy cooperation and Romania’s expansion plans for its sole nuclear power plant, Cernavoda. The delegation was led by Kathryn Huff, acting assistant secretary and principal deputy assistant secretary for the Office of Nuclear Energy.

Unit 2 at Pakistan’s Karachi nuclear power plant officially began commercial operation in late May, gaining the distinction of being the first Hualong One reactor outside of China to do so, China National Nuclear Corporation announced last week. Construction of Karachi-2 began in August 2015, and connection to the grid was accomplished in March of this year.

A collaboration agreement signed by Ontario Power Generation’s Center for Canadian Nuclear Sustainability, Canadian Nuclear Laboratories, and SNC-Lavalin will build on Ontario’s extensive nuclear industry expertise and skilled workforce to support the decommissioning of CANDU reactors in Canada and around the world, according to a May 13 press release from the organizations. The work will include the decommissioning of OPG’s Pickering nuclear power plant following the end of commercial operations in 2025.

Ontario Power Generation’s Centre for Canadian Nuclear Sustainability (CCNS) will collaborate with nuclear technology firm Moltex Energy on a project aimed at recycling used fuel from CANDU reactors, the electricity generator announced March 30.

The CCNS will provide C$1 million (about $800,000) in funding to assist Moltex in demonstrating the technical viability of its process to recycle used CANDU fuel. That process, known as WAste to Stable Salt (WATSS), has the potential to reduce storage needs for used fuel, according to Moltex.

Speaking last week at a virtual event of the Empire Club of Canada, Bruce Power president and chief executive officer Mike Rencheck announced “NZ-2050”—the company’s strategy for helping Canada achieve its stated goal of net-zero emissions by 2050.

Canada’s only private sector nuclear generator, Bruce Power operates the Bruce Nuclear Generation Station, located in Kincardine, Ontario. The plant houses eight units, all CANDU pressurized heavy-water reactors, with a total output of 6,288 MWe.

U.S. Energy Secretary Dan Brouillette and Romania’s Minister of Economy, Energy, and Business Development Virgil Popescu initialed a draft intergovernmental agreement on October 9 to cooperate on the construction of two additional reactors at the Cernavoda nuclear power plant, as well as the refurbishment of Unit 1.

According to a Department of Energy news release, the agreement, once formally executed, will “lay the foundation” for Romania to “utilize U.S. expertise and technology.” The deal marks a major change in Romania’s plans for its sole nuclear plant, as up until early this year the source for that expertise and technology was expected to be China.

The latest phase of the Darlington nuclear power plant’s refurbishment project began last week with the start of the defueling of Unit 3, according to Ontario Power Generation (OPG). Originally scheduled to begin in May this year, Unit 3’s refurbishment was postponed due to the COVID-19 pandemic.

Located in Clarington, Ontario, Canada, the Darlington plant houses four 878-MWe CANDU pressurized heavy-water reactors, all of which entered commercial operation in the early 1990s. The 10-year refurbishment project—which was 10 years in the planning—commenced in earnest in October 2016, when Unit 2 was taken off line (NN, Dec. 2016, pg. 45). The refurbished Unit 2 was returned to service in early June, and in late July Unit 3 was shut down and disconnected from the grid in preparation for its refurbishment.
