Road to advanced nuclear: How DOE and industry collaborations are paving the way for advanced nuclear reactors

April 2, 2021, 8:58AMNuclear NewsCory Hatch

As electric utilities rush to reduce carbon emissions by investing in intermittent renewables such as wind and solar, they often rely heavily on fossil fuels to provide steady baseload power.

More than 60 percent of the nation’s electricity is still generated with fossil fuels, especially coal-fired and gas-fired power plants that have the ability to quickly ramp up or ramp down power to follow loads on the electric grid. Most experts agree that even with a radical advancement in energy storage technology, relying exclusively on wind and solar to replace fossil fuels won’t be enough to maintain a stable electric grid and avoid the major impacts of climate change.

To complete the transition to a carbon-free energy future, one key piece of the puzzle remains: nuclear power.

GAIN vouchers connect three companies with national lab experts

The Gateway for Accelerated Innovation in Nuclear (GAIN) announced that three nuclear technology companies—Radiant, Oklo, and Lightbridge—will receive GAIN nuclear energy vouchers to accelerate the innovation and application of advanced nuclear technologies. The second set of Fiscal Year 2021 awards was announced March 25.

Advanced reactors take center stage in Popular Mechanics

The January/February 2021 issue of Popular Mechanics hit subscriber mailboxes this week with a stark cover image of a single small reactor under the headline, “Tiny nuclear reactors are about to revolutionize American energy.” The story looks at advanced reactors as a pivotal step to “redeem nuclear’s stature in American energy.”

A good primer: The article does a good job introducing the casual reader to the idea that “bigger is no longer better” and that the future of nuclear power in the United States will most likely be “a combination of traditional large plants and smaller, safer megawatt reactors.”

Advanced reactors, including small modular reactors, show that nuclear is no longer a one-size-fits-all operation, the article notes. The industry now “is all about personalization,” says Ken Canavan, Westinghouse’s chief technical officer, who is quoted in the article. The capacity and scalability of SMRs “is just irreplaceable,” he adds.

The article explains that SMRs, microreactors, and other advanced reactor designs will be able to bring reliable, carbon-free power to small or remote locations, replacing fossil fuel power plants and supplementing the “resource-sucking downtimes left by renewables.”

Petition window opened for Oklo’s microreactor license application

The Nuclear Regulatory Commission has announced a notice of opportunity to intervene in an adjudicatory hearing on Oklo Power’s combined license application (COLA) for construction of a microreactor at Idaho National Laboratory. The notice, dated June 24, was published in the Federal Register on June 30, opening a 60-day window for petitions.

Oklo's 1.5-MWe fast spectrum design known as Aurora is the first advanced non–light-water reactor to be accepted for a licensing review by the Nuclear Regulatory Commission. Both the reactor’s design and the anticipated licensing process mark a major departure from large light-water reactor design and licensing.
