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.

OPG and Moltex join forces on recycled fuel project

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.

Ontario Power Generation’s (OPG) massive project to refurbish all of its Darlington nuclear power plant reactors has reached its first major milestone with the successful completion of Unit 2’s refurbishment and reconnection to Ontario’s electricity grid, the utility stated in a June 4 media release.

The Darlington plant, located in Clarington, Ontario, Canada, houses four 878-MWe PHWR CANDU reactors, all of which entered commercial operation in the early 1990s. The 10-year refurbishment project, which also was 10 years in the planning, began in earnest in October 2016, when Unit 2 was taken off line (NN, Dec. 2016, pg. 45).

Nucleoelectrica Argentina S.A. announced in July that it had entered into a contract with China National Nuclear Corporation to build a Chinese-sourced version of the traditional Canadian CANDU reactor at its Atucha site. This 800-MWe plant will be the fourth at the site (already occupied by two Siemens pressurized heavy water reactor plants, and the just-begun CAREM Small Modular Reactor plant) and the nation's fifth nuclear plant overall (adding in the CANDU plant at Embalse.) This new unit will be Argentina's most powerful nuclear unit, topping Embalse by 200 MWe.
