Exelon, owner and operator of the nation’s largest nuclear reactor fleet, has made clear its position on the massive infrastructure and social spending bills that federal lawmakers, at this writing, continue to haggle over.
“As world leaders convene in Glasgow for COP26 to address the climate crisis, the need for America to take action has never been more urgent,” said Chris Crane, Exelon’s president and chief executive officer, on Monday. “The bipartisan infrastructure agreement and the policy framework for Build Back Better legislation will make us more competitive globally, spur innovation and support good-paying jobs, protect current and future generations from the worst impacts of climate change, and cement America’s leadership on one of the most pressing challenges—and opportunities—of our time. The time to act is now, and we encourage lawmakers to pass these critical policies into law.”
A recently completed feasibility study by Westinghouse Electric Company and Bruce Power concludes that the eVinci microreactor is capable of providing cost-competitive clean energy to decentralized, off-grid markets in Canada.
In his article, “The nuclear policy America needs,” journalist Matthew Yglesias says upfront that he is not a “nuclear bro.” He is not a scientist or a nuclear engineer. But he is part of an open, online conversation about the energy policy decisions shaping our future. And in the article posted on newsletter platform Substack on October 12, Yglesias says that nuclear prospects should not be determined by a zero-sum competition between zero-carbon energy resources. Instead, he says, “What nuclear really needs is specific regulatory changes that would give advanced reactor designs a chance to prove themselves.”
By 2030, Kairos Power aims to demonstrate electricity production from a full-scale, 140-MWe fluoride salt–cooled high-temperature reactor, the KP-X. In service of that goal, Kairos plans to demonstrate Hermes, a scaled-down 35-MWth nonpower reactor, in Oak Ridge, Tenn.
Hermes is being built to “prove our ability to deliver affordable nuclear heat,” said Mike Laufer, Kairos Power chief executive officer and cofounder, as he explained Kairos’s plans to the local community during a September 28 webinar now available to view on demand. Laufer took questions, and Kairos took the opportunity to introduce a virtual open house that visitors can tour to view videos and interactive features and even submit comments.
Back in July, officials from the state of Tennessee and Kairos Power met in Nashville to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The demonstration facility is a scaled-down version of Kairos’s Fluoride Salt–Cooled High Temperature Reactor (KP-FHR), dubbed Hermes. The company first announced plans in December 2020 to redevelop the ETTP’s former K-33 gaseous diffusion plant site for construction of Hermes.
For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.
Researchers at Sandia National Laboratories have been expanding MELCOR—the severe accident modeling computer code used by the Nuclear Regulatory Commission to evaluate the safety of light water reactors—to study the small modular reactors and non-light-water advanced reactors that are under development. An article published in Sandia Lab News on August 27 describes in detail how MELCOR is being expanded to work with different reactor geometries, fuel types, and coolant systems.
The nuclear community continues its collective push to restore funding for the Versatile Test Reactor (VTR) project at Idaho National Laboratory for fiscal year 2022. We first heard from the Department of Energy’s Katy Huff, followed by Argonne National Laboratory’s Jordi Roglans-Ribas. Now add Nuclear News opinion columnist James Conca to the list of supporters hoping to change the minds of those in Congress regarding the crucial VTR project.
Companies, universities, and national laboratories across the United States are working together to develop and demonstrate advanced nuclear technologies. To deploy those technologies on a global scale and maximize U.S. efforts to combat climate change, technology developers eyeing the export market must navigate rules and recommendations designed to ensure that international safeguards, security, and nonproliferation standards are met. Understanding and, where appropriate, integrating these standards early in the development process is crucial for streamlining export and technology deployment.
At the box office or streaming at home, it’s fear, not truth, that sells. The laws of physics are swept aside, apocalypse is inevitable, and superpowered heroes wait until the last possible second to save the universe. It can make for great entertainment, but in the real world we need to stick with science over science fiction and be wowed by engineering, not special effects.
The truth is, science and innovation are incredible in their own right. From communications and machine learning to space travel and medical advances, technology is evolving in hyperdrive to solve real problems. With climate change and global warming here on earth, we don’t have to go looking for trouble in a galaxy far, far away.
Statement from Craig Piercy, Executive Director and CEO of the American Nuclear Society:
A bipartisan group of legislators has introduced a bill to invest in university nuclear science and engineering infrastructure, establish regional consortia to promote collaboration with industry and national laboratories, and support the development of advanced reactor technology. The National Nuclear University Research Infrastructure Reinvestment Act of 2021 (H.R. 4819) was introduced in the House of Representatives by Reps. Anthony Gonzalez (R., Ohio), Sean Casten (D., Ill.), Peter Meijer (R., Mich.), and Bill Foster (D., Ill).
Today, Tennessee governor Bill Lee joined Department of Economic and Community Development commissioner Bob Rolfe and Kairos Power officials in Nashville, Tenn., to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The company first announced its plans to redevelop the former K-33 gaseous diffusion plant site at the Heritage Center, a former Department of Energy site complex, in December 2020.

As indicated in the April issue of Nuclear News, development of advanced reactor concepts heavily emphasizes small modular reactors and microreactors. Promised features, such as capital cost savings, plant system simplification, implementation flexibility, and favorable operational responsiveness with passive safety behavior, all promote small reactors as desirable, non-carbon-emitting power sources to help satisfy future energy needs. In spite of the favorable up-front economics compared to large nuclear reactors, SMRs and microreactors do not provide the benefit of economy of scale that typically compensates for the high staffing demands associated with traditional, labor-intensive operations and maintenance (O&M) practices in the nuclear industry. To avoid the prospect that high staffing levels relative to unit power production will lead to unsustainable O&M costs for small reactors, a significantly higher degree of automation, to the point of near autonomy, is necessary. Essentially, the economy of automation is needed to offset the loss of economy of scale.
The American Nuclear Society sent a letter this morning to the chairman and the ranking member of the House Foreign Affairs Committee, urging them to oppose any amendments to H.R. 3524, the Ensuring American Global Leadership and Engagement Act, that would disallow U.S. cooperation with China in the field of civil nuclear energy.
The bill, introduced on May 25 by the Foreign Affairs Committee chairman, Rep. Gregory Meeks (D., N.Y.), was scheduled for markup by the committee this afternoon at 1:00 (EDT).
Molten salt reactor technology first gained popularity in the 1960s, through the Molten Salt Reactor Experiment program at Oak Ridge National Laboratory. Now, decades later, a technology known as the molten salt nuclear battery (MsNB) is being developed to support the growing need for carbon-free, reliable, independent, and compact sources of small-scale heat and electrical power.
The pace of advances in nuclear instrumentation, controls, and human-machine interface technologies and their deployment has increased in recent years and are essential to achieving the enhanced safety and improved economics of advanced reactors.
The theme of the 2021 ANS Virtual Annual Meeting—Breaking Through to Deployment—is a theme of action. It can take substantial momentum, shrewdly applied, to break through barriers.
Coolant flow around the fuel pins in a light water reactor core plays a critical role in determining the reactor’s performance. For yet-to-be-built small modular reactors, a thorough understanding of coolant flow will be key to successfully designing, building, and licensing first-of-a-kind reactors.
