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.

DOE awards $8.5 million to fund advanced nuclear projects

November 29, 2021, 3:00PMNuclear News

In its latest financial nod of encouragement to the U.S. nuclear industry, the Department of Energy has announced awards totaling $8.5 million to five industry-led projects, with the aim of accelerating the commercial deployment of advanced reactors and fuels.

The awards are funded via the Office of Nuclear Energy’s U.S. Industry Opportunities for Advanced Nuclear Technology Development funding opportunity, which, since 2017, has invested more than $215 million in advanced nuclear technologies. Solicitations are broken down into three pathways: first-of-a-kind nuclear demonstration readiness projects, advanced reactor development projects, and direct regulatory assistance.

Countdown to the ANS Winter Meeting

Excitement is building for the 2021 ANS Winter Meeting and Technology Expo, which will be ANS’s first-ever completely hybrid event. The Winter Meeting will take place at the Washington Hilton in Washington, D.C., from November 30 to December 3, which is later than normal because the original venue for the Winter Meeting closed in the early days of the COVID-19 pandemic.

Terrestrial Energy and Cameco examine partnership for deploying IMSR Generation IV nuclear power plants

  • Terrestrial Energy and Cameco Corporation have signed a non-binding and non-exclusive memorandum of understanding to examine potential partnership opportunities to deploy Terrestrial Energy’s Integrated Molten Salt Reactor (IMSR) Generation IV nuclear power plants in North America and worldwide. The partnership would also evaluate possible opportunities for the supply of uranium, fuel, and other services. As part of these activities, the companies are investigating the potential of Cameco’s Port Hope uranium conversion facility in Ontario, Canada, for IMSR fuel salt supply.

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.

A look at SMRs for Australia

The Minerals Council of Australia (MCA) last week released Small Modular Reactors in the Australian Context, an overview of SMRs, their potential role in Australia, and their likely operating costs.

The 36-page report, written by Australian nuclear energy advocate Ben Heard, takes a look at three of the most advanced SMR designs currently undergoing regulatory approval: NuScale’s Power Module, GE-Hitachi’s BWRX 300, and Terrestrial Energy’s Integral Molten Salt Reactor.

Terrestrial Energy upgrades IMSR plant design

Terrestrial Energy has upgraded the design of its Integral Molten Salt Reactor (IMSR) nuclear power plant, the company announced on September 14. The proposed facility will now feature 390 MWe of generation capacity for grid supply from twin reactors and generators.

OPG resumes planning for new nuclear at Darlington

Ontario 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.

Testing for Terrestrial Energy’s IMSR under way with research partners

November 19, 2020, 7:00AMNuclear News

Terrestrial 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.”

Advanced reactor marketplace

October 29, 2020, 10:35AMNuclear News

Advanced reactor developers see potential markets for reactors in a range of sizes that offer clean, reliable, flexible, and cost-competitive power. Many have reached agreements with suppliers, utilities, and others to support the demonstration and possible deployment of their designs. Nuclear News is following these activities. Read on for updates and check back with Newswire often for more on the Advanced Reactor Marketplace.

Canada has invested Can$20 million in Terrestrial Energy’s 195-MW Integral Molten Salt Reactor through the Ministry of Innovation, Science and Industry, the company announced on October 15. In accepting the investment, Terrestrial Energy, which is based in Oakville, Ontario, has committed to creating and maintaining 186 jobs and creating 52 co-op positions nationally. In addition, Terrestrial Energy is spending at least $91.5 million on research and development. According to the company, the funds will assist with the completion of a key pre-licensing milestone with the Canadian Nuclear Safety Commission.

Two days earlier, Terrestrial Energy USA and Centrus Energy announced that they had signed a memorandum of understanding to evaluate the logistical, regulatory, and transportation requirements to establish a fuel supply for Integral Molten Salt Reactor power plants, which would use standard-assay low-enriched uranium at an enrichment level less than 5 percent.
