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.

The main construction phase for Unit 3 at Egypt’s El Dabaa nuclear power plant project has begun, Russia’s state-owned nuclear energy corporation Rosatom announced last week.

On December 20, 1951, researchers used energy produced by Experimental Breeder Reactor-I near Arco, Idaho, to illuminate four 200-watt lightbulbs. Since then, utilities have built commercial nuclear power plants in the United States almost exclusively to generate electricity. This has worked well alongside other power generation and transmission infrastructure—large oil- and coal-fired, natural gas turbine or hydroelectric plants, and a relatively simple electrical grid designed to deliver reliable power.

Humanity is now embarking on an epic and complex energy transformation across the grid, industry, and transportation. Renewables like wind and solar are contributing an increasing share of carbon-free electricity to the grid, but that contribution is variable and hard to predict—sometimes those sources produce more electricity than the grid needs, and sometimes less.

This month’s Nuclear News takes a look at nuclear’s reliability as an energy source, along with its contributions to the overall resiliency of our electricity grid. Capacity factors in the U.S. remain at an all-time high, and nuclear’s strength in maintaining a functional electricity distribution system in times of stress, whether by storm or war, is gaining public acceptance and appreciation.

Earlier this spring, the Nuclear Regulatory Commission hosted its first in-person Regulatory Information Conference (RIC) since the onset of COVID. Though well organized and informative, it was easy to sense the frustration of attendees—over things like the stringency of the NRC’s proposed Part 53 regulatory framework for advanced reactors and the perceived lack of preparedness for the coming onslaught of license applications. There was a general sense, as one friend put it, that the commission is “wrapped around the axle of administrative procedures and precedents.”
