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.

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.

. . . 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.

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.

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.
