A major step toward the creation of the most precise atomic clock ever—with an accuracy of one second in 300 billion years—was recently reported in Nature by an international team of researchers working at the European X-Ray Free-Electron Laser (XFEL) facility. The researchers, led by senior physicist Yuri Shvyd’ko of Argonne National Laboratory, created a pulse generator based on the element scandium that demonstrated an extremely narrow resonance frequency capable of maintaining unprecedented time accuracy.

Atomic and nuclear clocks: In atomic clocks, the electrons in the atomic shells of certain elements—most commonly cesium—are raised to higher energy levels with microwave radiation. The microwave frequency is tuned to maximize the radiation absorption within a particular resonance range.

German-based radiopharmaceutical biotech company ITM Isotope Technologies Munich and Canadian Nuclear Laboratories are launching a new joint venture company for the industrial-scale production of actinium-225, which is used in targeted alpha therapies to fight cancer. The new company is being called Actineer.

The Unit 3 reactor at Slovakia’s Mochovce nuclear power facility has completed the commissioning process, becoming a full-fledged member of the country’s nuclear fleet, plant owner Slovenské Elektrárne has announced.

Among the typical bustle of outage activities at the Surry Power Station in Virginia during the fall of 2022, an unfamiliar sound broke through the commotion. Even with hearing protection in place, a faint whir thunk, whir thunk, whir thunk could be heard, announcing the arrival of the latest innovation in nuclear power. Dominion Energy, owner and operator of Surry, had combined new technologies from robotics company Boston Dynamics and radiation detection company Gamma Reality Inc. to provide radiological condition monitoring throughout the plant that could protect technicians from radiation exposure. The result? A quadruped robot with real-time 3D radiation mapping and data fusion capabilities.

Ousmane Hisseine, an assistant professor of civil engineering at McMaster University in Hamilton, Ontario, is using his expertise in concrete infrastructure in hopes of improving the safety of small modular reactors.

The Department of Energy has released two additional requests for information related to its Cleanup to Clean Energy initiative, which aims to repurpose certain DOE-owned lands—portions of which were previously used during the nation’s nuclear weapons program—into sites for clean energy generation, including include solar, geothermal, wind, and nuclear electricity.

In the last few years, public investment in both new and existing nuclear technology has expanded alongside a rise in public support and acceptance. Now is the perfect time for the nuclear industry to seize this momentum by coming together to maintain current nuclear plants, expanding the nuclear workforce, strengthening the supply chain and infrastructure, increasing public- and private-sector investments, and continuing to advocate for the benefits of nuclear power.

Texas-based Vistra Corporation was hoping to get the go-ahead from the Federal Energy Regulatory Commission this month for its proposed acquisition of Energy Harbor’s nuclear assets, but on October 13, the agency issued an order extending its review of the deal (called “tolling the time” in bureaucratese) to April 11, 2024. Currently down one seat, the four-member FERC voted 3–1 for the time extension, with the lone dissent coming from commissioner James Danly.

Ultra Safe Nuclear (USNC) announced on October 17 that it had been awarded a contract by NASA to develop and mature space nuclear thermal propulsion (NTP) systems to advance the nation’s cislunar capabilities. Under the contract, USNC says it will manufacture and test proprietary fuel and simultaneously collaborate with its commercial partner, Blue Origin, to mature the design of an NTP engine optimized for near-term civil science and cislunar missions.

Nuclear energy stocks “have become far more compelling to many investors in recent years,” and “there are good reasons to support this carbon-free source of energy,” according to investment entrepreneur and financial lecturer Jason Hall. In an article recently published by The Motley Fool, Hall discusses the opportunities and risks of investing in nuclear energy companies and offers his perspective on three top nuclear energy stocks.

Nuclear basics and new innovations: Hall started at the beginning, describing the most basic aspects of nuclear energy: the production of heat through fission, the generation of electricity via turbines, and the mining and enrichment of uranium for fuel. He noted that there “are only a small handful of companies with the expertise and financial strength to deal with nuclear reactors, and almost all are either private, state-owned, or the subsidiary operation of a large industrial conglomerate.”

Bill Loeb, a charter member of the American Nuclear Society who was present at ANS’s founding and who served as a naval officer during World War II, passed away this year at the age of 98. Loeb was active in the nuclear workforce after his military service, founding a company that provided food preserved with gamma radiation to the U.S. Army in Vietnam. Loeb maintained his ANS membership and “lived an active, full life,” according to his youngest son, Jonathan.

Baton Rouge, La.-based Aptim Federal Services announced that the U.S. Army Corps of Engineers, Baltimore District, has awarded the company a six-year, $95.5 million contract to decommission, dismantle, and dispose of the SM-1A nuclear power reactor at Fort Greely, Alaska.

The Department of Energy announced $7 billion on October 13 to launch seven regional Clean Hydrogen Hubs (H2Hubs) across the country and accelerate the commercial-scale deployment of clean hydrogen. Two of the seven hubs will feature hydrogen production using electricity—and possibly steam—from nuclear power. The federal government’s multibillion-dollar investment will be matched and exceeded by more than $40 billion from the awardees, for a total investment in clean energy and job creation near $50 billion.

The Nuclear Regulatory Commission has docketed an application from Dominion Energy South Carolina for the subsequent license renewal (SLR) of the V. C. Summer plant’s Unit 1 reactor. The action was announced in Monday’s edition of the Federal Register.

Anyone involved in the nuclear power industry could tell you that the operation of nuclear power plants is a demanding and never-ending endeavor. Our machines are complex, our challenges are diverse, and our standards are unyielding. The truth is, however, many of us stay in this field because there’s something at the heart of what we do that makes it all worthwhile.

Westinghouse has signed a contract with Rolls-Royce SMR to develop a fuel design for the British firm’s small modular reactor program, the companies announced last week.

The design work, to be undertaken in the United Kingdom and the United States, will include associated core components and will be based on an existing Westinghouse pressurized water reactor fuel assembly design.

This summer, the American Nuclear Society supported two student members who participated in the Washington Internships for Students of Engineering (WISE) Program, a nine-week program that gives engineering and technology students the chance to spend a summer learning about public policy. This year’s ANS-sponsored WISE interns, Sarah Cole of Boise State University and Abbey Hageman of the University of Nevada–Reno, arrived in Washington, D.C., in May, where during the course of the program they made professional contacts, researched and presented policy papers (published in the WISE Journal of Engineering and Public Policy), and learned how government officials make decisions on complex technological issues—and how engineers contribute to this process.

Operating costs for nuclear units have grown significantly since the start of the commercial nuclear power industry. For nuclear power generation to remain competitive, process efficiencies and innovations will need to be introduced. The challenge for any change is to improve the safe operation of the nuclear unit. An area of opportunity to reduce operating costs while improving operational safety is through upgraded fuel design and manufacturing. At Southern Nuclear, the pressurized water reactor fuel engineering team worked with Westinghouse to implement the PRIME fuel features, where simple improvements would yield safer operation and long-term cost-savings due to a more robust fuel design. Implementing the PRIME fuel ensures that the operator’s burden from fuel performance is minimized while keeping the reactor unit in a safe operating condition.
