Westinghouse Electric Company, Bechtel, and Polish utility Polskie Elektrownie Jądrowe (PEJ)—the three firms leading the effort to build Poland’s first nuclear power plant—have announced the signing of a new agreement that defines the main principles of cooperation on the project’s design and construction and confirms the implementation of its next major stage.

Seven sites in southwestern Virginia have been identified as “competitive hosting grounds” for small modular reactors by a feasibility study Dominion Engineering, Inc. (DEI) prepared for the LENOWISCO Planning District Commission. (The planning district, based in Duffield, Va., serves the counties of Lee, Wise, and Scott and the city of Norton.) At a May 22 press conference at LENOWISCO’s offices, DEI chemical engineer and principal investigator Chuck Marks said the review represents the “very early stages of, does this region have what it takes to site one of these reactors, successfully deploy and successfully operate. And the answer is overwhelmingly yes,” according to an article in the Cardinal News.

NuScale Power announced yesterday that it has joined the Romanian Atomic Forum, aka Romatom, as a supporting member “to champion the association’s nuclear energy goals and further the next generation of advanced nuclear technology experts, technologists, and operators in Romania.” The move further deepens the American small modular reactor company’s commitment to the deployment of a VOYGR SMR plant in the Central European state.

Both current and advanced nuclear are among the clean energy sources that will be required to reach the Biden administration’s declared goal of a zero-carbon U.S. electricity sector by 2035, concludes a new report from the Department of Energy.

On the Path to 100% Clean Electricity, released last week, features a list of 10 actions the authors consider necessary for meeting that climate commitment. The full report can be accessed here.

On the sidelines of the G7 summit in Hiroshima, Japan, over the weekend, the Biden administration and partners Japan, South Korea, and the United Arab Emirates announced a public-private commitment of up to $275 million to support the advancement of NuScale Power’s small modular reactor project in Romania.

NuScale Power and steel manufacturer Nucor have signed a memorandum of understanding to explore the deployment of NuScale’s VOYGR small modular reactor plants at Nucor’s scrap-based electric arc furnace (EAF) steel mills, the Portland, Ore.–based SMR developer announced Tuesday.

Lee

In his latest effort to promote the growth of nuclear energy in his state, Tennessee Gov. Bill Lee signed an executive order on Tuesday to establish the Tennessee Nuclear Energy Advisory Council.

“Tennessee is ready-made to lead America’s energy independence and drive continued economic growth with safe, clean, and reliable nuclear energy for the future,” Lee said at a news conference held at the University of Tennessee’s Knoxville campus to publicize the document. “Today, I’m signing an executive order that will continue our work to make Tennessee the number-one state for nuclear energy companies to invest and thrive, bringing greater opportunity and quality jobs for Tennesseans.”

Santa Clara, Calif.–based Oklo is planning to build its second and third commercial Aurora Powerhouse nuclear plants in southern Ohio, the company announced yesterday. The advanced reactor developer received a site permit in December 2019 from the Department of Energy to build its initial Aurora facility at Idaho National Laboratory.

According to the announcement, Oklo has signed an agreement with the Southern Ohio Diversification Initiative (SODI), a community-reuse organization, to deploy two 15-MWe plants on land owned by SODI at the Portsmouth site near Piketon, Ohio. The DOE began transferring parcels of the Portsmouth site—home to the Portsmouth Gaseous Diffusion Plant, now undergoing decontamination and decommissioning—to SODI in June 2018 for economic development.

Reports released this week point to a clean energy future fueled by atomic energy—if and when pressing supply chain issues can be resolved. Advanced Reactor Roadmap, Phase 1: North America, released on May 15 by the Electric Power Research Institute and the Nuclear Energy Institute, takes a broad look at the deployment of advanced fission reactors and identifies supply chain ramp-up as one key enabler. The Fusion Industry Supply Chain: Opportunities and Challenges, released by the Fusion Industry Association on May 17, focuses on fusion energy supply chain issues.

Westinghouse Electric Company has signed a contract with Dominion Energy to design, manufacture, and deliver replacement steam generators for Virginia’s Surry plant, the nuclear technology firm announced Tuesday.

Ontario–based Terrestrial Energy announced yesterday that its U.S. branch has been awarded a regulatory assistance grant from the Department of Energy to support the company’s Nuclear Regulatory Commission licensing program for the Integral Molten Salt Reactor (IMSR) plant.

Bruce Power has awarded a 10-year, C$1.3 billion (about $970 million) fuel channel and feeder replacement (FCFR) contract to Shoreline Power Group for the remaining major component replacement (MCR) projects scheduled for Bruce Units 4, 5, 7, and 8.

NuScale Power has announced the opening of its fifth Energy Exploration (E2) Center, at the University Politehnica of Bucharest, in support of the small modular reactor developer’s ongoing collaboration with the U.S. and Romanian governments and Nuclearelectrica, operator of Romania’s Cernavoda nuclear power plant.

Avram

At a recent meeting of the Southwest Virginia Energy Research and Development Authority, advanced nuclear was on the docket for discussion. According to an article in the Bristol (Va.) Herald Courier, Dominion Energy vice president for business development Emil Avram discussed Dominion’s plans for developing advanced nuclear facilities featuring small modular reactors in southwestern Virginia, as well as the company’s vision regarding other energy sources.

Avram’s May 9 talk came at a time when Virginia is at the forefront of national efforts to deploy commercial SMRs. Gov. Glenn Youngkin has pledged that the commonwealth will be the first to build and deploy a commercial SMR, with plans to locate it in the coalfield region of southwestern Virginia.

Just days after immediately achieving key-player status in the small modular reactor market with the unveiling of its AP300 SMR, Westinghouse Electric Company on May 9 announced the filing of the new unit’s preapplication regulatory engagement plan with the Nuclear Regulatory Commission.

The plan outlines the preapplication activities Westinghouse intends to carry out with NRC staff to support the AP300’s licensing. According to the announcement, the plan documents the basic design philosophy of the technology, an overview of the proposed licensing approach, and a timeline for the planned preapplication interactions between the NRC and Westinghouse, with the goal of soliciting agency feedback on noteworthy topics.

Dow and X-energy have announced the location of their Xe-100 small modular reactor deployment project: Dow’s UCC Seadrift Operations manufacturing site in Texas. According to a May 11 joint news release, the SMR plant will provide the Seadrift site with power and heat as the site’s existing energy and steam assets near the end of their operational lives.

On September 1, 1859, amateur astronomer Richard Carrington was observing sunspots when a bright flash—a solar flare—erupted from the sun’s surface.

Unbeknownst to Carrington, the solar flare was accompanied by two large expulsions of magnetically charged plasma, what is now known as a coronal mass ejection. That plasma traveled 150 million miles in just 17.6 hours before slamming into the Earth’s magnetic field, inducing strong electrical currents under the Earth’s surface that today could impact electrical circuits across a significant area of the planet.

Washington state has trouble on the horizon—trouble with its electrical grid. Trouble as in not being reliable. Trouble as in big risks of rolling blackouts.

The trouble stems from attempts to decarbonize our society. Getting rid of coal, oil, and gas in generating electricity is the low-hanging fruit, but just getting rid of them without a realistic plan to replace them will do more harm than good.

Flipping on a light switch and knowing that the power will come on is a luxury. While it sounds like a simple act, it is achieved through deliberate government policies that ensure our electricity comes from a mix of sources, some of which are continuously operational—such as nuclear and gas—and some of which only operate at certain times—such as wind and solar. If any one source is unavailable or overly expensive, another source needs to deliver on demand. Diversity of energy sources ensures the grid is able to adapt and recover from changing conditions so that we can always flip the lights on.

While grid resilience—the grid’s ability to anticipate, absorb, and recover from major disruptions and rapidly restore electric service in their wake—is a matter of paramount importance, the source diversity required to achieve this is at risk. For power grids relying on renewables, supply and demand hang in a balance based on time of day and weather.

A recent multinational survey of attitudes toward nuclear energy has found widespread public support for advanced nuclear technologies in countries around the world, according to the 50-page report The World Wants New Nuclear, released yesterday by nongovernmental organizations ClearPath, Third Way, Potential Energy Coalition, and RePlanet.

The report is based on a large-scale online quantitative survey across three continents, among 13,500 members of the general public. Nationally representative samples were surveyed for each of eight nations—France, Germany, Japan, Poland, South Korea, Sweden, the United Kingdom, and the United States—between November 2022 and January 2023.
