Three companies that are part of a larger collaboration to develop and demonstrate Natrium, the fast reactor design recently introduced by TerraPower and GE Hitachi Nuclear Energy (GEH), were invited to participate in a webinar hosted by ClearPath to talk about Natrium’s design, fuel requirements, and load-following potential.

The September 21 webinar, titled “Natrium: Latin for Sodium, Big for Advanced Nuclear,” was moderated by Rich Powell, executive director of ClearPath, and featured TerraPower’s Chris Levesque and Tara Neider, Centrus Energy’s Dan Poneman, and Duke Energy’s Chris Nolan.

TerraPower announced on September 15 that it plans to work with Centrus Energy to establish commercial-scale production facilities for the high-assay, low-enriched uranium (HALEU) needed to fuel many advanced reactor designs.

The proposed investment in HALEU fuel fabrication is tied to a TerraPower-led submittal to the Department of Energy’s Advanced Reactor Demonstration Program (ARDP), which was created to support the deployment of two first-of-a-kind advanced reactor designs within five to seven years. TerraPower would like one of those designs to be Natrium, the 345-MWe sodium fast reactor that it has developed with GE Hitachi Nuclear Energy.

The board of directors of the Energy Communities Alliance (ECA), an organization known more for its work in advancing the cleanup of Department of Energy sites, is launching a new initiative aimed at supporting the development of new nuclear technologies. As announced by the ECA on September 15, the self-funded, one-year initiative will focus on small modular reactors, micro and advanced reactors, a skilled nuclear workforce, and new nuclear missions around DOE facilities. facilities.

“With growing bipartisan support for nuclear energy in Congress, new federal demonstration projects led by DOE and the Department of Defense, and notable investment from the private sector, local governments want to be meaningfully engaged—and prepared—to match the strengths and needs of our communities with new nuclear opportunities,” the ECA said in its announcement.

As the voice of American nuclear engineers and scientists, ANS congratulates NuScale Power for receiving the first-ever final safety evaluation report for a small modular reactor issued by the U.S. Nuclear Regulatory Commission.

The Natrium reactor and energy system architecture, recently introduced by TerraPower and GE Hitachi Nuclear Energy (GEH), offers baseload electricity output from a 345-MWe sodium fast reactor with the load-following flexibility of molten salt thermal storage. Stored heat can be used to boost the system’s output to 500 MWe for more than five and a half hours when needed, according to TerraPower. A company representative told Nuclear News that the company expects a commercial Natrium plant to cost $1 billion or less.

The Department of Energy announced on August 14 that $5.1 million would go to the Electric Power Research Institute (EPRI) to develop modular-in-chamber electron beam welding capabilities to support reactor pressure vessel welding for NuScale Power’s small modular reactor design. The project has a total value of nearly $6.5 million, of which the DOE will provide about $5.1 million.

Shaping a regulatory framework to support future innovation

Session organizers Amir Afzali and Brandon Chisholm of Southern Company crafted a session titled “Advanced Reactors: Innovation in Nuclear Technology Needs Agile, Efficient, and Predictable Regulatory Framework” in the Regulatory Relations track of the UWC Virtual Summit. The panel discussion was focused on how to enable innovation in a regulated industry to support advanced reactor deployments within 10 years. “The right regulatory framework can enable innovation, and right-sizing the regulatory requirements incentivizes innovation,” Chisholm said during his opening comments.

A new report from the Nuclear Innovation Alliance, U.S. Nuclear Innovation in a Global Economy: Updating an Outdated National Security Framework, argues for the repeal of the Atomic Energy Act’s restriction on foreign ownership, control, or domination of nuclear reactors—the so-called FOCD provision.

Republicans on the House Energy and Commerce Committee on July 29 continued their push for nuclear with the introduction of the Nuclear Prosperity and Security Act (H.R. 7814) and the Modernize Nuclear Reactor Environmental Reviews Act (H.R. 7817). Last month, GOP members of the committee introduced the Strengthening American Nuclear Competitiveness Act and the Nuclear Licensing Efficiency Act.

In an 86 to 14 vote, the Senate on July 23 passed the National Defense Authorization Act (NDAA) for Fiscal Year 2021, incorporating by amendment S. 903, the Nuclear Energy Leadership Act (NELA). The House of Representatives passed its version of the NDAA, which supports $740 billion in funding for national defense, earlier in the week in a less bipartisan manner, 295 to 125. Members of both chambers will now begin negotiations to hammer out a final bill to send to the president—a process that could take months.

The Nuclear Regulatory Commission has extended the deadline for comments on its “Proposed Rule for Emergency Preparedness for Small Modular Reactors and Other New Technologies” to allow more time for members of the public and other stakeholders to develop and submit their comments. The proposed rule and associated draft regulatory guide apply to non-light-water reactors and certain nonpower facilities, and were originally published in the Federal Register on May 12 with a deadline of July 27. The new deadline is September 25.

All energy sources, including small modular reactors, are being considered to meet Puerto Rico’s energy needs, U.S. Coast Guard Rear Admiral Peter J. Brown said on July 15 during the second day of PR-Grid Virtual, a three-day online conference on Puerto Rico’s energy grid. Brown’s comments were quickly circulated on Twitter by people who are already working to make nuclear power a reality for Puerto Rico, including members of the Nuclear Alternative Project (NAP), a non-profit organization of Puerto Rican engineers in the nuclear industry.

As industry steps up its efforts to design, develop, and deploy advanced reactors, codes and standards must be developed to support these technologies. Toward that end, ANS and the Nuclear Energy Institute collaborated to host a virtual workshop on June 23 for industry partners to discuss the development of advanced reactor codes and standards.

NEI’s senior director of new reactors, Marc Nichol, welcomed more than 400 attendees to the online meeting, and ANS’s director of government relations, John Starkey, outlined the meeting logistics.

With a new generation of nuclear reactors in the works, Idaho National Laboratory has embraced digital engineering (DE) as a means of achieving the same efficiencies that companies in the private sector have been able to realize in everything from concert halls to aircraft engines.

DE—using advanced technologies to capture data and craft design in a digitized environment—has been evolving since the 1990s. For Mortenson Construction, a worldwide construction firm, using virtual design and construction resulted in a cumulative 600 days saved over 416 projects and a 25 percent increase in productivity. By building digital twins for assets, systems, and processes, DE has avoided more than $1.05 billion in customer, production, and mechanical losses.

Leaders at INL recognized in 2018 that DE could be useful in the design and construction of new commercial and test reactors. Managing construction costs, timing, and performance will be essential to maintain U.S. competitiveness.

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.

The ANS Young Members Group and the Gateway for Accelerated Innovation in Nuclear (GAIN) on June 18 presented a webinar on the rapidly developing prospects for advanced nuclear in Puerto Rico. Behind those bright prospects is the Nuclear Alternative Project (NAP), which led a Department of Energy–funded study on the feasibility of using small advanced reactors to meet the island’s power needs.

The American Nuclear Society and the Nuclear Energy Institute have organized a workshop for industry partners to discuss standards needs to support advanced reactors. The workshop will be conducted virtually through the Zoom platform

The workshop will be held on Tuesday, June 23, from 10:00 a.m. to 4:30 p.m. (EDT).

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.

The final plenary session of the American Nuclear Society's 2020 Virtual Annual Meeting was the General Chair’s Special Session, held on Wednesday, June 10. The session contained much information about the current and future role of advanced reactor technology. The session, with the subtitle “The Promise of Advanced Reactors during Uncertain Times: National Security, Jobs and Clean Energy,” featured two panels: the Lab Directors Roundtable and the Advanced Reactor Panel. The general chair is Mark Peters, Idaho National Laboratory director. The session was moderated by Corey McDaniel, of Idaho National Laboratory, and the assistant general chair of the Annual Meeting.

A few of the issues covered during the dual plenary session included challenges to advanced reactor deployment, public-private partnerships in research and development, nuclear non-proliferation and security, workforce issues, and market conditions and demand.

The Nuclear Regulatory Commission is taking comments on its “Proposed Rule for Emergency Preparedness for Small Modular Reactors and Other New Technologies,” published in the Federal Register on May 12. The proposed rule and associated draft regulatory guide apply to non–light-water reactors and certain nonpower facilities.
