Nuclear News

Centrus Energy announced February 9 that it has finished assembling a cascade of uranium enrichment centrifuges and most of the associated support systems ahead of its contracted demonstration of high-assay low-enriched uranium (HALEU) production by the end of 2023. When the 16-machine cascade begins operating inside the Piketon, Ohio, American Centrifuge Plant, which has room for 11,520 machines, it will be the first new U.S.-technology based enrichment plant to begin production in 70 years.

Estonia’s Fermi Energia has selected GE Hitachi Nuclear Energy’s BWRX-300 small modular reactor for potential deployment in that European country, GEH announced on February 8.

The Nuclear Regulatory Commission recently presented its proposed 30-month licensing review timeline of TRISO-X’s planned fuel fabrication facility at the project’s first-ever public meeting in Oak Ridge, Tenn.

TRISO-X, a subsidiary of X-energy, has requested a 40-year license to possess and use special nuclear material to manufacture advanced fuel. The facility would be the first-ever commercial-scale fuel fabrication plant focused on using high-assay low-enriched uranium (HALEU).

The Belgian government is exploring the idea of extending the operational life of its three oldest reactors by two years, a variety of news outlets are reporting.

Those reactors—Units 1 and 2 at the Doel facility and Unit 1 at Tihange, sporting a combined capacity of 1,852 MWe—were slated to be permanently shuttered in 2025 in keeping with the country’s nuclear phase-out policy.

The Nuclear Regulatory Commission has issued the final supplemental environmental impact statement (EIS) for SHINE Technology’s application for a license to operate a medical isotope production facility in Janesville, Wis.

One of the duties of the ANS president is to visit with American Nuclear Society student sections. As some of you know, I have been doing this both in person and virtually. Although meeting via Zoom and other platforms is easier in terms of scheduling and travel, there is nothing like being able to interact face to face. Visiting student sections in person has been the highlight of my time as president. As I have stated on several occasions, the enthusiasm and excitement I have seen among the nuclear engineering students in the U.S. is nothing short of exhilarating!

When we think of workforce planning, those of us who have had long associations with universities naturally think first of undergraduate and graduate nuclear engineering programs at our universities, but this is of course only a part of the overall solution. The first—and in many ways the most important—part of workforce development is getting our nation’s youth excited about nuclear science and technology.

Work has begun to prepare the Savannah River Plutonium Processing Facility (SRPPF) at the Department of Energy’s Savannah River Site in South Carolina for its future national security mission: the manufacturing of plutonium pits for the National Nuclear Security Administration.

X-energy Canada, a subsidiary of U.S. mall modular reactor and fuel technology company X-energy, has signed a memorandum of understanding with Invest Alberta Corporation (IAC) to develop economic opportunities in support of the potential deployment of the Xe-100 SMR in the western Canadian province. (Alberta is one of four provinces behind last year’s A Strategic Plan for the Deployment of SMRs—a document that maps the path to capitalizing on the benefits of advanced reactor deployment.)

Tokamak Energy announced on February 6 that it has built a world-first set of high-temperature superconducting (HTS) magnets, to be assembled and tested in fusion power plant–relevant scenarios.

This month’s Nuclear News focuses on the challenges of building and maintaining a strong, productive nuclear technology workforce. While my sense is that U.S. nuclear is in significant growth mode, I’ve made a habit of asking our Utility Working Conference and Winter Meeting exhibitors, “What is the most significant challenge you face today?” The answer is almost always some form of “finding good talent.” Conversely, ask any nuclear engineering student about their career prospects, and you will likely get a confident response, so it seems that multiple offers are becoming the norm in the nuclear tech employment market.

Of course, empirical data is harder to come by. A 2019 study by the National Association of State Energy Officials and the Energy Futures Initiative found 60,916 workers employed in U.S. nuclear power generation, with another 9,406 employed in the nuclear fuels sector. But we still lack good, publicly available numbers for national labs, universities, and suppliers, as well as any job focused on nonnuclear applications of nuclear technology.

The nuclear community is undergoing a moment of unprecedented interest and growth not seen in decades. The passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act are providing a multitude of new funding opportunities for the nuclear community, and not just the current fleet. A mix of technologies and reactor types are being evaluated and deployed, with Vogtle Units 3 and 4 coming on line later this year, the Advanced Reactor Demonstration Projects of X-energy and TerraPower, and NuScale’s work with Utah Associated Municipal Power Systems to build a first-of-a-kind small modular reactor, making this is an exciting time to join the nuclear workforce.

Finland’s Radiation and Nuclear Safety Authority (STUK) recently provided the country’s Ministry of Economic Affairs and Employment with a positive safety review of the Loviisa reactors, bringing the plant closer to an approval for operation to 2050.

The International High-Level Radioactive Waste Management conference plenary, held in November during the 2022 ANS Winter Meeting, highlighted tight communication among physical, social, and political science experts as the key to successful waste management programs. The four featured speakers provided an international perspective on this issue.

A 16-university team of 31 scientists and engineers, under the title Consortium for Nuclear Forensics and led by the University of Florida, has been selected by the Department of Energy’s National Nuclear Security Administration (NNSA) to develop the next generation of new technologies and insights in nuclear forensics.

Unit 2 at Tihange, one of Belgium’s two nuclear power plants, was permanently disconnected from the grid late on the evening (local time) of January 31, operator Engie Electrabel has announced.

The 1,008-MWe pressurized water reactor is the second unit in Belgium’s nuclear reactor fleet to be retired in accordance with the country’s 20-year-old law mandating a gradual phase-out of nuclear power. The first Belgian unit to be retired, Doel-3, a 1,006-MWe PWR, was shut down on September 23, 2022. Remaining in operation are Doel-1, -2, and -4 and Tihange-1 and -3.

Xcel Energy subsidiary Northern States Power Company has submitted to the Nuclear Regulatory Commission a subsequent license renewal application for the utility’s Monticello reactor. Notice of the agency’s receipt of the application was published in the January 31 Federal Register.

At my company, Dow, we understand and embrace our responsibility to reduce global carbon emissions. With that said, the challenge to decarbonize is significant but achievable. To give you a sense of the scale required for us to decarbonize in order to make our products, we produce more than 7 GW of power and steam that fire more than 50 gas and steam turbines and boilers. Moreover, we have more than 100 furnaces at 30 major manufacturing sites worldwide.

Dow has already reduced our greenhouse gas emissions by 15 percent since 2005, and we are on track to reduce emissions another 15 percent by the end of the decade on our path to carbon neutrality by 2050. Our use of clean energy has contributed significantly to our current progress, as we are one of the top 20 users of renewable energy among global corporations, having secured more than 900 MW of renewable power. While we will continue to pursue renewable energy, there’s a limitation in the ability for renewables to support our decarbonization efforts.

"At 1:23 p.m. load dissipaters from the generator were connected—electricity flows from atomic energy.” These were the words Walter Zinn wrote in the log after the first four light bulbs were illuminated by nuclear energy. The year was 1951, and the EBR-­I was about to show the world what nuclear energy had to offer.

Framatome and Ultra Safe Nuclear announced on January 26 that they intend to form a joint venture to manufacture commercial quantities of tristructural isotropic (TRISO) particles and Ultra Safe’s proprietary fully ceramic microencapsulated (FCM) fuel.

The companies have signed a nonbinding agreement to integrate their resources to bring commercially viable, fourth-generation nuclear fuel to market for Ultra Safe’s micro-modular reactor (MMR) and other advanced reactor designs.

In the 1960s, Alvin Weinberg at Oak Ridge National Laboratory initiated a series of studies on nuclear agro-­industrial complexes¹ to address the needs of the world’s growing population. Agriculture was a central component of these studies, as it must be. Much of the emphasis was on desalination of seawater to provide fresh water for irrigation of crops. Remarkable advances have lowered the cost of desalination to make that option viable in countries like Israel. Later studies² asked the question, are there sufficient minerals (potassium, phosphorous, copper, nickel, etc.) to enable a prosperous global society assuming sufficient nuclear energy? The answer was a qualified “yes,” with the caveat that mineral resources will limit some technological options. These studies were defined by the characteristic of looking across agricultural and industrial sectors to address multiple challenges using nuclear energy.
