Fusion startup Type One Energy has announced the publication of a baseline physics design basis for its proposed Infinity Two stellarator fusion pilot power plant. The design basis was published in a series of seven papers in a special issue of the Journal of Plasma Physics. According to the company, the design basis realistically considers for the first time the relationship between competing requirements for plasma performance, power plant startup, construction logistics, reliability, and economics utilizing actual power plant operating experience.

Dow and X-energy announced today that they have submitted a construction permit application to the Nuclear Regulatory Commission for a proposed advanced nuclear project in Seadrift, Texas. The project could begin construction later this decade, but only if Dow confirms “the ability to deliver the project while achieving its financial return targets.”

The American Nuclear Society launched its inaugural Nuclear 101 certificate course at the 2024 ANS Winter Conference and Expo in November. The five-day program, which is designed to provide participants with a robust understanding of nuclear energy and engineering, was the talk of the conference, with nearly 50 attendees from different nuclear organizations participating in the course.

I think so. The near future for nuclear depends on both the cabinet picks for Energy, Defense, Interior, and Commerce, and how well the new secretaries stick to the Project 2025 plan, the Heritage Foundation’s conservative blueprint for the future.

Those who want to read the entire 900-­page Mandate for Leadership can find it easily online. The section relating to nuclear power and waste begins on page 363: “Department of Energy and Related Commissions,” by Bernard L. McNamee. The nuclear weapons–related portions are scattered throughout.

It is obvious from the beginning of the chapter that McNamee doesn’t really understand the Department of Energy. He can be forgiven, since most people don’t. For the several months following their appointments, new energy secretaries generally fail to understand what the DOE does—except for real nuclear folks like Ernest Moniz, who held the position from 2013 to 2017. Most think that the DOE is all about energy, when really it is mostly about weapons and waste.

Savannah River National Laboratory said it has received a patent for its radially oriented honeycomb structures. The technology offers a solution to the deformation of cylindrical honeycomb structures when they are formed from flat panels, providing a way to create structures with greater wall thickness than traditional methods.

In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

Hagerty

Blackburn

In a strongly worded opinion piece published by Power Magazine on March 24, Tennessee Sens. Marsha Blackburn and Bill Hagerty call for new leadership at the Tennessee Valley Authority to jumpstart its small modular reactor program.

The GOP lawmakers are looking to President Donald Trump and Energy Secretary Chris Wright to overhaul TVA’s board of directors to drive America’s role in the nuclear renaissance. TVA is the first and only U.S. energy company to obtain an early site permit for a small modular reactor, but the utility has not progressed on physical deployment of a unit since the permit was awarded in 2019.

For many of us, the height of our accomplishments with Lego blocks might have been constructing little square houses as children. For others, these versatile building blocks are a medium for creating complex models of sophisticated machinery—models that have practical and educational applications. One such individual is ANS member Vincent Lamirand, a reactor physicist at the École Polytechnique Fédérale de Lausanne (EPFL) Laboratory for Reactor Physics and Systems Behavior (LRS) in Switzerland.

The University of Sheffield announced that it has engaged in a new £1 million (about $1.29 million) research partnership with Sellafield Ltd., the U.K. Nuclear Decommissioning Authority, and the U.K. National Nuclear Laboratory that will seek to address some of the challenges of nuclear waste encapsulation by looking at new cement technologies to provide safe and reliable disposal solutions.

Johnston

John Bennett Johnston Jr., a moderate-to-conservative Democrat who served four terms in the U.S. Senate (1972–1997) and often advocated for the energy and infrastructure interests of his home state of Louisiana, passed away on March 25 at the age of 92. Johnston was a strong supporter of Louisiana’s oil and natural gas sectors and nuclear energy expansion.

Johnston was born on June 10, 1932, in Shreveport, La. He left Shreveport to attend the U.S. Military Academy at West Point and then Washington and Lee University in Virginia. He earned his juris doctorate in 1956 from Louisiana State University. From 1956 to 1959, he served as a first lieutenant in the U.S. Army’s Judge Advocate General (JAG) Corps.

The Korea Times has reported that a Department of Energy contract employee at Idaho National Laboratory has been terminated for trying to take INL-owned, export-controlled, proprietary nuclear reactor design software on a flight to South Korea. The individual was stopped while attempting to board a Korea-bound flight with the design software, according to a formal report that the DOE Office of the Inspector General submitted to Congress for the period October 2023–March 2024.

. . . and today

Ralph Cooper in 1955. . .

Variety characterized my career: in profession (engineer, physicist, educator), in field (energy, space, defense), in technology (fusion, lasers, nuclear), and in community (STEM diversity, scouting, social service).

After earning my energy engineering degree from The Cooper Union in New York and my Ph.D. in physics from the University of Illinois, I was most excited by Los Alamos Scientific Laboratory’s 1957 program (pre-Sputnik) to develop a nuclear rocket engine. There I worked on everything from reactor physics to vehicle design and mission analysis. I participated in the Gardner Committee that recommended the Apollo program, a thrill for a young scientist.

Nuclear Waste Services recently hosted a group of five teenagers for a week of exposure to real-world nuclear industry work environments at its facilities in Calderbridge, Cumbria, in northwestern England. The youth learned about career opportunities and leadership responsibilities at the company. They engaged with senior management and performed activities with several different NWS teams, including the environmental, waste characterization, cybersecurity, geological disposal facility grants, and human resources departments.

The Department of Energy reissued a $900 million solicitation on March 24 designed to de-risk the deployment of “Gen-III+” light water small modular reactors. The same funding was previously offered in October 2024, with applications due January 17. Now, potential applicants have until April 23 to apply for a grant under a solicitation modified to “better align with President Trump's bold agenda to unleash American energy and AI dominance.”

As Western countries accelerate their decarbonization efforts, nuclear power is set to play a key role in achieving net-zero emissions by 2050. For instance, the United Kingdom’s goal of expanding nuclear capacity to 24 gigawatts by mid-century, meeting 25 percent of projected electricity demand, highlights the need for reliable, low-carbon energy sources. As the world’s top uranium producer, Kazakhstan is poised to be a vital partner in this transition, supplying the fuel that powers nuclear reactors and supports the U.K.’s and other Western countries’ clean energy goals.

At COP28 in 2023, the International Atomic Energy Agency emphasized the urgent need to accelerate deployment of nuclear power to achieve net-zero carbon emissions. This sentiment was reinforced the following year at COP29, where 31 countries committed to tripling nuclear capacity by 2050 to meet global climate goals. These developments highlight the growing recognition of nuclear energy’s role in providing reliable, low-carbon power essential for a sustainable future.

The opening of an Energy Exploration (E2) Center at Rensselaer Polytechnic Institute in Troy, N.Y., was announced by NuScale Power Corporation on March 24. The training center will provide students from RPI’s School of Engineering an opportunity to gain a firsthand understanding of advanced nuclear technology and the role it will play in the global energy transition, as well as of the features and functionality of NuScale’s small modular reactor technology.

The Nuclear Waste Technical Review Board has recommended to the Department of Energy and Congress that they work together “to create a workable pathway to site, license, construct, and operate a geologic repository for the permanent disposal of spent nuclear fuel and high-level radioactive waste.”

A bill that would fully repeal the state’s entire moratorium on new nuclear projects survived a key deadline in the Illinois General Assembly last week.

To stay afloat in the spring legislative session, bills needed to be assigned to committee by March 21, and state Sen. Sue Rezin’s Senate Bill 1527 now sits with the Senate’s Energy and Public Utilities committee for review.

A group of students recently visited the Department of Energy’s Savannah River Site, near Aiken, S.C., to get a close look at L Area, a facility the DOE considers critical to nuclear materials management and nonproliferation missions at the site.

The primary culprits behind contamination in a nuclear facility are fission products resulting from nuclear reactions and activated corrosion products like rust and metal. While these radioactive materials remain within the reactor system, the risk of contamination is minimal. However, the reality of a complex network of pipes and valves introduces vulnerabilities, leading to potential leaks and spills. The necessity for periodic system openings, required for sampling and maintenance, further heightens the risk of contamination. Once outside the system, radioactive materials can disperse, jeopardizing other plant components, areas, and even personnel.
