Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

The Department of Energy announced a cost-shared award on November 10 valued at about $150 million for American Centrifuge Operating, a subsidiary of Centrus Energy, to complete the high-assay low-enriched uranium (HALEU) demonstration project it began in 2019. After delays that Centrus attributes in part to the COVID-19 pandemic, the company now has until the end of 2023 to produce the first 20 kilograms of HALEU enriched to 19.75 percent U-235 from the 16-centrifuge cascade it has installed in a DOE-owned Piketon, Ohio, facility—the only U.S. facility currently licensed to produce HALEU.

Here is a recap of industry happenings over the past month:

ADVANCED REACTOR MARKETPLACE

U.S. and Canadian regulators formalize relationship on advanced reactors

The U.S. Nuclear Regulatory Commission and the Canadian Nuclear Safety Commission (CNSC) have reached a charter agreement that formally establishes a collaborative relationship on small modular reactors and other advanced reactor technologies. The two agencies have been cooperating on these technologies for several years, but the formal agreement is designed to better harmonize the American and Canadian regulatory processes to achieve safe, successful deployment. The charter specifically focuses on regulatory and safety issues regarding the licensing review of GE--Hitachi’s BWRX--300 SMRs, which Ontario Power Generation (OPG) has selected for deployment at its Darlington site and which the Tennessee Valley Authority (TVA) plans to build at Clinch River. OPG and TVA announced plans earlier this year to work together on the development and deployment these SMRs.

Deploying a fleet of advanced reactors in the 2030s means deploying high-assay low- enriched uranium (HALEU) infrastructure now.

The future fleet will need more than 40 metric tons of HALEU by 2030, according to Department of Energy projections. Getting to the 5–20 percent fissile uranium-235 content of HALEU involves either enriching natural or low-enriched uranium (LEU) or downblending high-enriched uranium (HEU).

Because downblending the limited stocks of HEU held at the DOE’s Idaho National Laboratory and Savannah River Site is a short-term option at best, the Energy Act of 2020 authorized a HALEU Availability Program to build a sustainable enrichment infrastructure by the time advanced reactors are ready for commercial deployment.

Comments on a request for information reached the DOE in February 2022, just before Russia’s invasion of Ukraine amplified global energy security concerns. While the war in Ukraine didn’t change the DOE’s plans, it “accelerated everything,” said Kathryn Huff, who leads the DOE’s Office of Nuclear Energy (DOE-NE) as assistant secretary. “Our attention is now laser-focused on this issue in a way that it wouldn’t have been in the past.”

The Department of Energy is providing $38 million in funding for a dozen projects aimed at developing technologies to advance spent nuclear fuel reprocessing, reduce the volume of high-level waste requiring permanent disposal, and provide domestic advanced reactor fuel stocks. The projects are being led by universities, private companies, and national laboratories.

NuScale Power announced October 20 that the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards (ACRS) issued a letter the previous day agreeing with NRC staff’s approval of NuScale’s methodology for determining the plume exposure pathway emergency planning zone (EPZ). As approved, the methodology would permit a smaller EPZ—dependent on site-specific conditions, including seismic hazards—that provides the same level of protection to the public as the 10-mile radius EPZs used for existing U.S. nuclear power plants.

Eddie Guerra, VP of Civil Infrastructure: Our energy infrastructure is undergoing an unprecedented transformation, which is in turn opening a new wave of challenges for deploying the next generation of nuclear reactors.

The decentralization of power generation will require nuclear plants to be sited closer to demand centers. As the future grid becomes more distributed, energy--intensive customers will demand proximity and flexibility, and new--generation reactors will need to accommodate the intermittency and load--following requirements that a greener and more dynamic grid will pose. Added to that, nuclear projects will need to compete economically within a more liberalized electricity market. Advanced reactor deployments will face unprecedented challenges in today’s world, and in the future.

Despite challenges, advances in engineering and technology point to a very bright future. Smaller reactors with enhanced safety features will allow stakeholders to rethink proximity criteria on siting, opening doors for deployment in new scenarios: university campuses, municipalities in remote areas, or industrial conglomerates, just to name a few.

The Nuclear Regulatory Commission last Friday announced the publication of its ninth report to the Convention on Nuclear Safety, describing the federal government’s actions under the convention to achieve and maintain safety for the nation’s nuclear power reactor fleet.

An International Atomic Energy Agency treaty, the Convention on Nuclear Safety was adopted in 1994 and entered into force in 1996. In 1999, it was ratified by the U.S. Senate.

The aim of the convention, according to the IAEA, is to “commit contracting parties operating land-based civil nuclear power plants to maintain a high level of safety by establishing fundamental safety principles to which states would subscribe.” Signatories are required to submit reports for peer review at meetings held every three years.

Who better to talk with about the licensing of nuclear facilities and materials than Christopher T. Hanson, the chairman of the five-member Nuclear Regulatory Commission? Hanson is the principal executive officer of and official spokesman for the NRC. As a collegial body, the Commission formulates policies, develops regulations governing nuclear reactor and nuclear material safety, issues orders to licensees, and adjudicates legal matters.

As energy security and environmental concerns prompt some countries to increase their reliance on nuclear energy or become first-time adopters of the technology, the U.S. government must decide whether it will offer financing for reactor exports—a move that poses financial risks but could create jobs, address global climate and energy security challenges, and limit Chinese and Russian influence. A new report released on August 25 by the Center on Global Energy Policy at Columbia University’s School of International and Public Affairs, Comparing Government Financing of Reactor Exports: Considerations for U.S. Policy Makers, digs into the history of nuclear reactor financing and delivers recommendations for U.S. policymakers.

Matt Bowen, research scholar at the center and the report’s lead author, told Nuclear News, “Given how important financing is to countries considering new reactor construction, as well as the competition that U.S. vendors face from foreign state-owned entities, Congress and the White House should both focus attention on the issue, including policy options to increase U.S. competitiveness.”

Representatives of Ultra Safe Nuclear Corporation (USNC) of Seattle, Wash., and Hyundai Engineering of Seoul, South Korea, traveled last week between USNC project sites in Oak Ridge, Tenn., and Ontario, Canada, to sign two agreements extending their collaboration on the deployment of USNC’s high-temperature, gas-cooled Micro Modular Reactor (MMR). The agreements expand on a business cooperation agreement signed in January 2022 and an engineering agreement signed in June, and follow the closure earlier this month of a previously announced $30 million equity investment after its review by the U.S. Treasury Department’s Committee on Foreign Investment in the United States.

The American Nuclear Society is offering the hour-long members-only webinar “Inflation Reduction Act: What's in it for nuclear?” on Friday, August 26, starting at 1:00 p.m. EDT.

What it’s about: With the Inflation Reduction Act (IRA) now signed into law, an expert panel will discuss its impact on nuclear in the coming years. The panelists will explore what it will mean for existing nuclear power plants, the deployment of advanced reactors, the production of high-assay low-enriched uranium (HALEU), hydrogen, and more.

Register now for the webinar.

Luria

Reps. Elaine Luria (D., Va.) and Byron Donalds (R., Fla.) have introduced in the House of Representatives the Fueling Our Nuclear Future Act (H.R. 8723), a measure to accelerate the availability of commercially produced high-assay low-enriched uranium (HALEU) fuel and boost domestic energy production in the United States.

Unveiled last week following a Senate version introduced in April by Sen. John Barrasso, the legislation directs the secretary of energy to prioritize and establish a program that ensures a domestic supply of HALEU for advanced nuclear reactors. Currently, the nation lacks the domestic enrichment capability to produce HALEU. The bill explicitly excludes uranium sourced or processed by any entity owned or controlled by the governments of Russia and China.

At the June ANS Annual Meeting in Anaheim, Calif., our Executive Director/CEO Craig Piercy used an interesting acronym: he said, “This meeting is so exciting we are going to give nuclear professionals FOMO with respect to ANS meetings going forward.” The term “fear of missing out” was common a few years ago, but I had not heard it recently. So when Craig used it, it really caught my attention. Craig was, of course, correct that the Annual Meeting was great: technically interesting, productive, and great fun, as well. It provided a wonderful opportunity to learn, network, and advance both academic and business goals. However, in thinking about this phrase I realized that in a lot of ways, getting people to realize how important nuclear science and technology is for making the world better is a lot like trying to get people to understand that they are truly missing out.

Energy Secretary Jennifer Granholm visited Idaho National Laboratory on August 3 to meet with INL staff, including director John Wagner, as she toured key research facilities on INL’s 890-square-mile site and the lab’s campus in Idaho Falls.

Crowell

Caputo

The Senate last evening confirmed by voice vote Annie Caputo and Bradley R. Crowell to seats on the Nuclear Regulatory Commission, returning the agency to its full, five-member complement. Caputo’s term expires in June 2026, Crowell’s in June 2027.

Nominated by President Biden in May to serve on the commission, Caputo and Crowell appeared before the Senate Environment and Public Works (EPW) Committee on June 8 to field questions. On July 27, the EPW Committee unanimously approved both and sent their nominations to the Senate floor.

In a 243–187 vote, the House of Representatives yesterday passed the CHIPS and Science Act of 2022, a $280 billion economic competitiveness package aimed at bolstering U.S. semiconductor manufacturing, as well as scientific research and development, including nuclear energy R&D.

The Nuclear Regulatory Commission recently approved, in a 2–1 vote, a recommendation from its staff that could potentially lead to the siting of advanced reactors in more densely populated areas than is permitted for traditional light water units.

NRC chairman Christopher Hanson and David Wright voted in favor of the recommendation, with Jeffery Baran casting the lone “nay” vote. (There are currently two open seats on the five-member commission.)
