“The world's largest chloride salt system developed by the nuclear sector” is now ready for operation in TerraPower’s Everett, Wash., laboratories. Southern Company, which is working with TerraPower through its subsidiary Southern Company Services to develop molten chloride reactor technology, announced on October 18 that the Integrated Effects Test (IET) was complete. The multiloop, nonnuclear test infrastructure follows years of separate effects testing using isolated test loops, and it was built to support the operation of the Molten Chloride Reactor Experiment (MCRE) at Idaho National Laboratory that the companies expect will, in turn, support a demonstration-scale Molten Chloride Fast Reactor (MCFR).

German chancellor Olaf Scholz has provided what appears to be the final word on the fate of his country’s three remaining operating nuclear power plants.

Via an October 17 letter, Scholz informed economy and energy minister Robert Habeck, environment minister Steffi Lemke, and finance minister Christian Lindner of his decision to keep all three facilities operating “beyond 31 December 2022 until 15 April 2023 at the latest.” The order ends months of argument between Scholz’s two coalition partners—the stridently antinuclear Greens and the center-right Free Democrats (FDP)—regarding the plants’ continued operation. (Habeck and Lemke are Green Party members, while Lindner is with the FDP.)

After the Atomic Energy Act of 1946 ended collaboration between the United States and its World War II allies (specifically, the United Kingdom and Canada), the British government felt it necessary to go down its own path in developing nuclear technology. As a result, the Windscale Piles, in Seascale, Cumberland, England, were planned and built with the aim of producing plutonium for the U.K.’s defense purposes. Windscale Pile No. 1 became operational in 1950, and Windscale Pile No. 2 followed shortly after in 1951.

Early in the design process, the U.K. government came to realize that it did not have an adequately expansive piece of land that could provide a safety barrier in case of an issue at a water-cooled reactor. If the flow of water coolant were to be interrupted, an evacuation and exclusion zone could require a large land area that Britain simply did not have. The government, therefore, decided to construct both reactors with a natural draft air convection core cooling system. A massive cooling chimney at each reactor would soar nearly 400 feet into the air.

Finnish energy company Fortum has announced the launch of a two-year feasibility study to explore the potential for new nuclear construction, with a focus on Finland and neighboring Sweden. The utility said it will examine commercial, technological, and societal conditions for both conventional large reactors and small modular reactors.

The Department of Energy’s crucial Versatile Test Reactor (VTR) project is the focus of a newly released special issue of Nuclear Science and Engineering. This special issue of the American Nuclear Society’s flagship journal presents a current snapshot of the nuclear innovation project, which is being developed in partnership among the DOE’s Office of Nuclear Energy (NE), six national labs, and a host of industry and university partners.

Haghighat

Join North Carolina State University’s Department of Nuclear Engineering for the 2022 Nuclear Engineering Distinguished Technical Lecture on Thursday, October 20, from 4:00 to 5:00 p.m. EDT.

Alireza Haghighat, professor and director of the nuclear engineering program in the Department of Mechanical Engineering at Virginia Tech, will deliver a presentation, “New Paradigm for Real-Time, High-Fidelity Particle Transport Simulation with Monte Carlo Accuracy.”

Workers at the Department of Energy’s Savannah River Site have achieved an 85 percent reduction in the site’s operational footprint, a percentage that will grow as decommissioning and demolition of facilities continue in the site’s massive D Area, according to the DOE.

Gov. Whitmer

While the fate of Michigan’s Palisades nuclear plant remains uncertain, Gov. Gretchen Whitmer has approved legislation requiring a feasibility study to examine the potential for new nuclear generation in the state.

Signed into law last Friday, House Bill 1609 instructs the Michigan Public Service Commission to engage an outside consulting firm to conduct the study.

The measure was introduced in the House on April 14 by Rep. Graham Filler (R., 93rd Dist.) and passed that chamber on May 19, 85–20. On September 28, the bill passed even more comfortably in the Senate, 32–4.

The mandated study is due to the governor and leaders of the state legislature in 18 months.

The Department of Energy’ Office of Legacy Management (LM) will be conducting verification and validation work at abandoned uranium mines in the Navajo Nation of northeastern Arizona during the fall field season, which runs from mid-October to mid-December.

Arguably, nowhere does a more robust safety culture exist than in nuclear, an industry that is a model of a learning organization, dedicated to continuous improvement through transparency in identifying and correcting errors and failures. Over the course of maintenance and outage planning, the cornerstones of reactor safety are considered in every decision regarding maintenance and outage activities. Radiation monitoring systems in nuclear power plants are vital to plant safety and regulatory compliance. In addition to the 10 CFR 20 applications, the industry relies on radiation monitors for measuring effluents (RG 1.21, RG 4.15, and Part 50 App A GDC 64), reactor pressure boundary leakage (RG 1.45), and PWR primary to secondary leakage, and to assist in emergency classification (RG 1.97). The Nuclear Regulatory Commission’s well-intended Maintenance Rule places maintenance priorities on systems, structures, and components (SSCs) used to mitigate accidents and SSCs used in emergency operating procedures (EOPs). The Maintenance Rule also includes SSCs whose failure could prevent a safety-related SSC from fulfilling its safety-related function and SSCs whose failure could cause a reactor scram or actuation of a safety-related system. Unfortunately, the narrow scope of the Maintenance Rule leaves a significant portion of radiation monitoring systems outside the scope of the rule, which often delays repairs.

“Why did a tiny leak bring down a hugely successful research reactor 25 years ago?”

That’s how Robert P. Crease, an academic who writes a regular column for Physics World, introduces The Leak: Politics, Activists, and Loss of Trust at Brookhaven National Laboratory, a book he wrote with former interim BNL director Peter D. Bond that was published this month by MIT Press.

“Were this story fiction, its characters, plot twists and ironies would be entertaining,” Crease writes in his October 5 Physics World post about the book. “But because it’s fact, it’s a tragicomedy.”

Some two weeks after unveiling his state’s 2022 Energy Plan, Virginia Gov. Glenn Youngkin has announced his intention to include $10 million in the state’s next budget proposal—due in December—to create the Virginia Power Innovation Fund for research and development of nuclear, hydrogen, carbon capture and utilization, and battery storage technologies.

Recently, while reading an editorial by William Roper in the journal Science,* I was struck by the fact that the health care industry, in the past two or three years, has been experiencing some of the same challenges our industry has had for the past 40 years. Roper opines on the situation that scientists and health care professionals have had to face in a country that is divided not only along political and ideological lines but also about what constitutes the facts. He goes on to highlight that many scientists think there is a need to get the politics out of public health, while many policymakers (who are frequently politicians) think scientists are not the best people to be making public policy decisions. He also notes that of late, “political leaders, media personalities, and ordinary citizens have proclaimed their own ‘alternative facts.’”

As much as I would like to say something like “join the boat”—our scientific community has had to deal with “alternative facts” for years—I would much rather say to the health care community that we can and should all be striving for the same thing: to help the thought leaders of our world understand that we can only succeed if we are all willing to be in the same boat, working together to fix the problem.

Leaders of X-energy and its TRISO-X subsidiary gathered on October 13 to break ground at the site of what X-energy bills as “North America’s first commercial-scale advanced nuclear fuel facility” in Oak Ridge, Tenn. X-energy expects the TRISO-X Fuel Fabrication Facility (TF3) to create more than 400 jobs and to be commissioned and operational by 2025.

Rose

Hruby

The Department of Energy’s National Nuclear Security Administration reported last week that NNSA administrator Jill Hruby and principal deputy administrator Frank Rose completed a trip to Kazakhstan on October 5 to meet with the country’s government officials. The trip served as a chance for Hruby and Rose to thank the officials for the nonproliferation and nuclear security partnership that exists between the United States and Kazakhstan. According to the NNSA, notable achievements under the partnership include Project Sapphire (see more below), the conversion of three research reactors, and efforts to counter nuclear smuggling.

“Russia and China have overtaken the United States as the world’s premier nuclear-power exporters.” Or so states an article recently published by Defense One, an online news source that primarily reports about national defense and security matters. The article notes that Russian and Chinese reactor designs have accounted for 87 percent of new installed nuclear reactors worldwide during the past five years and that China is set to become the world’s leading nuclear power producer before 2030.

Duke Energy’s Harris nuclear power plant’s 24th refueling outage began in early October. The plant, located in New Hill, N.C., is a 964-MWe Westinghouse three-loop pressurized water reactor that started commercial operation in May 1987.

Georgia Power announced this morning that fuel loading at Vogtle-3 has commenced, marking an important milestone on what has proved to be a long and bumpy road to startup and commercial operation of the first new nuclear power reactors to be built in the United States in more than three decades. (Major work on the Vogtle-3 and -4 project began in 2012, with a price tag of $14 billion and scheduled unit start dates of 2016 and 2017. The project’s total cost is now expected to exceed $30 billion.)

Canada’s Ontario Power Generation (OPG) and Czech Republic–based ČEZ have agreed to collaborate on nuclear technology deployment, including small modular reactors, under a memorandum of understanding signed yesterday in Prague.

Ontario’s largest electricity generator and the European energy giant have both pledged to achieve net-zero carbon emissions by 2040.
