Nuclear energy offers a pairing of high capacity factors and low carbon emissions unrivaled by other power sources, and advanced reactors and small modular reactors (SMRs) hold promise to deliver that power with even more efficiency and versatility. Researchers in the public and private sectors, backed by government funding through programs like the Department of Energy’s Advanced Reactor Demonstration Program and Advanced Research Projects Agency–Energy (ARPA-E), are bringing that promise closer to fulfillment by engineering solutions to open questions about advanced reactor materials and fuel cycles.

As part of its strategy to achieve net-zero status by 2050, the Tennessee Valley Authority yesterday issued a request for proposals for supplying up to 5 GW of carbon-free energy that must be operational before 2029.

Nesbit

Steven Nesbit, ANS’s immediate past president, is among the nuclear industry leaders quoted in a recent New York Times article about the renewed interest in nuclear power in the United States. The article explains that the challenges of meeting clean energy goals and surging electricity demands are prompting many government officials to take “a fresh look at nuclear power—both extending the life of existing reactors and building new ones.” The article also presents the views of some nuclear critics.

Much of the article focuses on the fate of California’s Diablo Canyon nuclear power plant, which is currently scheduled for shutdown in 2025. Several of the state’s lawmakers who previously supported the shutdown, including Gov. Gavin Newsom and Sen. Diane Feinstein, are now considering supporting the extended life of the plant. A joint study by Stanford University and the Massachusetts Institute of Technology has concluded that a 10-year extension of Diablo Canyon could substantially reduce carbon emissions, lessen reliance on natural gas, cut electricity costs, and minimize the risk of brownouts.

With the proper investment and policy support, advanced nuclear energy has the potential to become a key component of a future U.S. clean energy system, a new report from Berkeley, Calif.’s, Breakthrough Institute finds.

Released this morning, the 155-page Advancing Nuclear Energy: Evaluating Deployment, Investment, and Impact in America’s Clean Energy employs “a high-resolution nationwide model of the United States electricity sector to demonstrate how advanced nuclear reactors might play a major role in a least-cost plan to transition the power grid entirely to clean energy sources by 2050, assuming that the first advanced reactors are available for deployment by 2030,” according to the executive summary.

Nuclear power can play a significant role in helping countries solve the twin crises of energy and climate and securely transition to future energy systems dominated by renewables, according to a new report, Nuclear Power and Secure Energy Transitions: From Today’s Challenges to Tomorrow’s Clean Energy Systems, released June 30 by the International Energy Agency (IEA). The message is clear: Nuclear power can reduce reliance on imported fossil fuels, cut carbon dioxide emissions, and stabilize electricity systems; and building sustainable and clean energy systems will be harder, riskier, and more expensive without nuclear.

“Keeping Illinois nuclear plants open is saving some customers $237 a year on average,” reads the headline of a recent CNBC article about the Climate and Equitable Jobs Act, which was passed by the Illinois legislature and signed into law by Gov. J.B. Pritzker in September 2021. The legislation includes a provision to keep Illinois nuclear power plants open to meet the state’s clean energy goals, even if the facilities are not profitable.

“What if I told you that scientists had figured out a way to produce affordable electricity that was 99 percent safer and cleaner than coal or oil, and that this breakthrough produced even fewer emissions per gigawatt-hour than solar or wind?” That’s the question that Derek Thompson, a staff writer at The Atlantic, asks in his article, "The Forgotten Stage of Human Progress," before revealing, “The breakthrough I’m talking about is 70 years old: It’s nuclear power.”

From refugee in Bangladesh to top nuclear engineer at Idaho National Laboratory, ANS member Yasir Arafat has led quite an interesting life, as described in a recent online profile written by Donna Kemp Spangler for the INL website. Arafat is leading the development of the Department of Energy’s Microreactor Applications Research Validation and EvaLuation (MARVEL) project at INL. The profile notes that MARVEL, which Arafat envisioned soon after joining INL in 2019, is scheduled to be “built and demonstrated at INL’s Transient Reactor Test Facility and connected to the world’s first nuclear microgrid within two years.”

I often say that nuclear energy will play a key role in our clean energy future, and I believe that is true. However, it won’t happen automatically. There is no “divine right” behind nuclear energy. We like to admire the fascinating aspects of nuclear technology, but at the end of the day, it comes down to the money, and that’s where we stubbed our toe badly over the past two decades.

The “Nuclear Renaissance” foundered when advanced light water reactors turned out to be much more expensive than their marketing claimed, while alternatives—primarily natural gas—plummeted in price. We tend to point to impediments to nuclear technology, such as overly restrictive licensing requirements and adverse public opinion, but these matter only to the extent of their impact on the bottom line. Again, it comes down to the money.

Small modular reactor developer NuScale Power has signed a memorandum of understanding with three South Korean companies—Doosan Enerbility Company, GS Energy Corporation, and Samsung C&T Corporation—to explore the deployment of NuScale’s VOYGR power plants in Asia.

The American Nuclear Society hosted the webinar “Earth Day: Reflections on the Future of Clean Energy” on April 22. Expert panelists discussed the best options for achieving emissions-free objectives, including goals in energy production, industrial activities, and transportation.

In the transition from fossil fuels to clean energy, the highest-paying jobs will continue to be in the nuclear power industry, which provides significant and sustainable employment that benefits local and regional economies. That observation was made during a recent webinar sponsored by the International Atomic Energy Agency titled “Investing in Low Carbon Technologies: Job Creation for Just Energy Transitions.”

Representatives from the clean energy industry discussed how rising living standards and job creation around the world can be ensured as energy investments align to meet climate goals.

The Nuclear Innovation Alliance (NIA), a nonprofit advocating for advanced nuclear, has announced the publication of a new report, Fission Vision: Doubling Nuclear Energy Production to Meet Clean Energy Needs. According to the April 13 announcement, the United States needs a “focused national effort” to develop and deploy advanced nuclear technologies to help meet midcentury climate goals.

Current U.S. climate targets (set by the Biden administration) include a 50–52 percent reduction from 2005 levels in net greenhouse gas pollution by 2030 and a net-zero–emissions economy by 2050.

“Fission Vision answers the question: What is the role advanced nuclear energy could play at a scale and at a pace to help provide safe, reliable, and affordable clean energy?” said Judi Greenwald, NIA’s executive director. “Fission Vision has three objectives: catalyzing a robust U.S. innovation and commercialization ecosystem, ensuring ‘social license’ to operate advanced nuclear energy, and reimagining and integrating advanced nuclear energy with other clean energy sources. If we can achieve these objectives—and we think we can—advanced reactors will play a major role in meeting our climate and energy goals by at least doubling U.S. nuclear energy production by 2050.”

The American Nuclear Society is hosting a webinar, titled “Earth Day: Reflections on the Future of Clean Energy,” on Friday, April 22, from 11 a.m. to noon (EDT).

Notwithstanding the snubbing of nuclear in its recently released Green Bond Framework, the Canadian government is showing support for small modular reactors in its 2022 budget plan, which was presented to the House of Commons by the minister of finance, Chrystia Freeland, on April 7.

According to the Canadian Nuclear Association, “This is the first documented government policy that provides explicit financial support for SMRs as a key solution for climate change.”

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.

Holcomb

Indiana has joined the growing list of states looking into small modular reactors for future energy production as their coal-fired plants are retired.

Gov. Eric Holcomb on March 18 signed into law S. 271, which allows and incentivizes the construction of SMRs in Indiana. Introduced on January 10 and sponsored by state Sens. Eric Koch (R., Bedford) and Blake Doriot (R., Goshen), S. 271 passed in the Senate on February 1 in a 39–9 vote and in the House on February 22 by a vote of 70 to 22.

Specifics: S. 271 requires the Indiana Utility Regulatory Commission (IURC), in consultation with the state’s Department of Environmental Management, to adopt rules concerning the granting of certificates of public convenience for the construction, purchase, or lease of SMRs, defined as reactors with a rated electric generating capacity of not more than 350 MW. The rules are to be adopted by July 1, 2023.

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The May issue reviewed the economics of nuclear power and provided some great articles on nuclear power plant capacity factors, advanced reactor markets, the economic consequences of plant closures, plant closures as an opportunity for industry engagement with local communities, and the article below that looks at why the electricity markets are failing nuclear power plants.

The Biden administration has a goal to decarbonize the U.S. electricity sector by 2035.¹ Achieving this goal would require a massive nuclear power build program. The U.S. nuclear power industry’s size and historical success signal that we are in a good position to do this, but at present, the U.S. nuclear fleet is shrinking. Why is this so, and what can be done to turn the trend around?

A new study by researchers from Stanford University and the Massachusetts Institute of Technology—An Assessment of the Diablo Canyon Nuclear Plant for Zero-Carbon Electricity, Desalination, and Hydrogen Production—makes a compelling case that the 2018 decision to shut down California’s only operating nuclear power plants needs another look—and that revenue options could make reversing the decision not just feasible but economically attractive.

“Fast-forward three years and things have changed,” said Jacopo Buongiorno, a professor of nuclear science and engineering at MIT and one of the authors of the report, during a November 8 webinar. Since the decision was made to shut down Diablo Canyon’s twin pressurized water reactors in 2024 and 2025 when their current licenses expire, the state has passed bills calling for net zero carbon emissions by 2045 and for restrictions on land use that could effectively limit solar installation sprawl. Californian’s have also experienced repeated grid reliability issues and prolonged drought conditions.

As Congress awaited key votes yesterday on spending bills that include production tax credits for at-risk plants and a new amendment adding $500 million in supplemental funding over five years to increase the availability of high-assay low-enriched uranium (HALEU), the U.S. Senate Energy and Natural Resources Committee held a Full Committee Hearing On Potential Non-Electric Applications Of Civilian Nuclear Energy. Sen. Joe Manchin (D., W.V.), chairman of the committee, emphasized that “advanced nuclear reactors hold enormous potential to provide opportunity to communities across the country with zero-emission baseload power” and made it clear he expects new reactors to replace retiring coal plants in his home state of West Virginia.

Speaking before the committee were Shannon Bragg-Sitton of Idaho National Laboratory, Paul Chodak III of American Electric Power, and Michael J. Guastella of the Council of Radionuclides and Radiopharmaceuticals.
