California-based Oklo has received a $2 million cost-share award from the Department of Energy for the commercialization of advanced fuel recycling capabilities by using electrorefining technology. Oklo is matching $1 million in funds and is partnering with the DOE and Argonne National Laboratory on this public-private partnership, which is intended to help reduce fuel costs for advanced reactor designs while reducing waste by turning used fuel into advanced reactor fuel.

The Nuclear Innovation Alliance (NIA) yesterday released a report, Unlocking Advanced Nuclear Innovation: The Role of Fee Reform and Public Investment, arguing that a reform of the Nuclear Regulatory Commission’s user-fee model for new license applicants, combined with more funding for advanced reactor licensing and regulatory infrastructure, will unlock innovation and support U.S. leadership in advanced nuclear energy.

The 38-page report asserts that as currently structured, the NRC’s fee model inhibits carbon-free advanced nuclear innovation in two primary ways: First, it limits the agency’s resources, flexibility, and efficiency; and second, the open-ended costs associated with paying fees impose barriers to new entrants.

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.

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.”

Caroline Cochran, chief operating officer of Oklo Inc., and Sarah Bristol, PRA supervisor at NuScale Power, have given presentations recently for the American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) Community of Practice (CoP).

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.
