All three units at the Duke Energy’s Oconee nuclear power plant in South Carolina are now licensed to operate for an additional 20 years.

Dozens of Westinghouse employees and supply chain partners descended on Washington, D.C., last week to build legislative support for new nuclear projects.

A bill being considered in the Texas legislature would create a taxpayer-funded program to draw advanced nuclear projects to the state.

GOP state Rep. Cody Harris authored House Bill 14, which proposes use of public dollars to help fund nuclear construction, provide grants for reactors, and continue development research. The legislation would allocate up to $2 billion for a new Texas Advanced Nuclear Deployment Office and create within it a state coordinator position to assist in the state and federal permitting processes, according to Inside Climate News.

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.

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.

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.

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.”

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.

First Light Fusion announced last week that it has set a new record for the highest quartz pressure achieved on Sandia National Laboratories’ Z machine using its amplifier technology to achieve an output pressure of 3.67 terapascal (TPa)—roughly doubling the pressure the company reached in its first experiment on the machine one year ago.

Amid recent ceasefire talks between Russia and Ukraine, President Donald Trump suggested the U.S. should take control of Ukraine’s nuclear power plants for long-term security, the Associated Press reported.

“American ownership of those plants could be the best protection for that infrastructure,” Trump suggested, according to a later statement.

The final passage of Senate Bill 424 from Indiana’s House of Representatives last week sent a key piece of pronuclear legislation to Gov. Mike Braun for final approval.

The legislation offers public utilities that want to develop small modular reactors in the Hoosier State to recover preconstruction costs from their customers before the project even begins. The company would have to petition the Indiana Utility Regulatory Commission and, if approved, would have the opportunity to establish a new rate that reflects the cost of the project.

The Nuclear Regulatory Commission has received a request from the state of Connecticut asking that the state be allowed to assume regulatory authority over certain radioactive materials within state borders.

Fleischmann

U.S. Rep. Chuck Fleischmann is all about energy—specifically nuclear energy.

On March 20, the GOP congressman from Tennessee joined the official launch of Atoms for Appalachia, the new report from the Atlantic Council Global Energy Center that studied opportunities for deploying advanced nuclear energy in the area to spur economic development.

The council hosted a series of Atoms for Appalachia (A4A) workshops in 2024 in North Carolina, Pennsylvania, Tennessee, and West Virginia in partnership with the Breakthrough Energy Foundation. The sessions explored workforce demand, partnership opportunities, and innovation happening across the nuclear industry.

A pair of bills working their way through the Iowa statehouse aim to promote nuclear energy projects in the state—in part by changing how the plants would be regulated and funded.
