Bellevue, Wash.–based TerraPower has awarded three supplier contracts to U.S. companies to support its Natrium demonstration project, construction of which began in June 2024 in Kemmerer, Wyo. The new contracts represent the fifth round of procurement awards for the Natrium project.

Shine Technologies has been developing fusion-adjacent technologies in Janesville, Wis., including nuclear fuel recycling, since its founding in 2005. Standard Nuclear of Oak Ridge, Tenn., was formed just last year but holds a TRISO fuel production technology backed by years of research and development since it acquired Ultra Safe Nuclear’s fuel manufacturing assets after that company’s bankruptcy in October 2024. Now, Shine and Standard Nuclear have announced plans to work together on a “strategic partnership to advance nuclear fuel recycling and U.S. fuel security.”

So, President Trump has just kicked the low-dose radiation hornets’ nest.

Specifically, his recently signed executive order “Ordering the Reform of the Nuclear Regulatory Commission” calls for the NRC to “reconsider reliance” on the linear no-threshold (LNT) theory and the ALARA (as low as reasonably achievable) standard for radiation protection.

This directive will certainly reignite a vociferous debate within the radiation research community over the continued efficacy of using LNT as the basis for protecting the public and the environment, a community that has been wracked with controversy on this matter for the last few years.

I must admit that whenever the low-dose issue comes up, my first thoughts always go to Sayre’s Law.

Texas-based Vistra Corporation has announced that its license renewal application for the Perry nuclear power plant was approved by the Nuclear Regulatory Commission. The plant first connected to the grid in 1986 and is still operating under its original 40-year license, which was set to expire next year.

A recent appropriation from the Texas legislature and signed by Gov. Greg Abbott directs funding to Texas Tech University to accelerate “produced water” research in partnership with Abilene Christian University and Natura Resources and to complete the construction of a molten salt research reactor at ACU.

The International Atomic Energy Agency has initiated a coordinated research project that will combine an “innovative, non-invasive, and scalable nuclear technique”—gamma-ray spectrometry (GRS)—with drones and satellite imagery to gather and analyze data that can reveal the quality of soil on agricultural lands around the world.

The Nuclear Regulatory Commission has whittled down the timeline for reviewing TerraPower’s construction permit application for Kemmerer Power Station Unit 1 in Wyoming. Announcing a new, more aggressive schedule, the NRC said it aims to complete its review by the end of 2025, eight months earlier than originally planned.

As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.

A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

Westinghouse Electric Company announced that it has signed a $180 million contract with the ITER Organization for the assembly of the vacuum vessel for the fusion reactor being built in southern France. Designed to demonstrate the scientific and technological feasibility of fusion power, the ITER tokamak will be the world’s largest experimental fusion facility.

Global Laser Enrichment announced that it has submitted its safety analysis report to the Nuclear Regulatory Commission for the planned Paducah Laser Enrichment Facility (PLEF). This follows GLE’s December 2024 submission of the plant’s environmental report, now completing GLE’s full license application for NRC review.

Dominion Energy’s V.C. Summer nuclear power plant, in Jenkinsville, S.C., has been authorized to operate for 80 years, until August 2062, following the renewal of its operating license by the Nuclear Regulatory Commission for a second time.

In its June 30 announcement of a new deal to purchase 200 MW from Commonwealth Fusion Systems' (CFS) first ARC fusion power plant planned for Virginia, Google called it “the largest direct corporate offtake agreement for fusion energy” ever. While Google made no mention of its plans for the power, its press release noted that clean energy is needed to reduce data center emissions.

Meeting a deadline set in President Trump’s May 23 executive order “Reforming Nuclear Reactor Testing at the Department of Energy,” the DOE on June 30 updated information on its National Environmental Policy Act (NEPA) rulemaking and published an interim final rule rescinding existing regulations alongside new implementing procedures.

The Department of Energy’s Office of Nuclear Energy announced the recipients of “first call” 2025 Nuclear Science User Facilities (NSUF) Rapid Turnaround Experiment (RTE) awards on June 26. The 23 proposals selected from industry, national laboratories, and universities will receive a total of about $1.4 million. While each project is led by a different principal investigator, some call the same organization home. A total of 17 companies, labs, and universities are represented.

The World Bank and the International Atomic Energy Agency signed an agreement last week to cooperate on the construction and financing of advanced nuclear projects in developing countries, marking the first partnership since the bank ended its ban on funding for nuclear energy projects.

. . . and today.

Mosebey in 1984 . . .

I graduated from high school in 1969. My yearbook says my career ambition was to be a nuclear physicist. This was inspired by a paperback book I read: Men Who Made a New Physics by Barbara Lovett Cline. I enrolled as a physics student at Susquehanna University that fall and graduated four years later. Many job applications were sent out, but I quickly learned in any branch of physics you needed at least a master’s degree and preferably a Ph.D. So, I applied to the Penn State nuclear engineering program as a master’s degree candidate. This would not be nuclear physics, but it would be close enough. To help with expenses, Penn State had quite a few internships with branches of Westinghouse, and mine was a three-month-long stint that summer at the Liquid Metal Fast Breeder Reactor project at Waltz Mill, Pa. My job was to work on expanding the uranium-238 fast fission cross sections into the 20-MeV range. Of course, I had no idea what a cross section was, but my supervisor, Gene Paik, and my office partners, especially Colin Durston, were immensely helpful.

Texas Tech University and Fermi America shared plans on June 26 to build “the world’s largest advanced energy and artificial intelligence campus” in Amarillo, Texas, near the Pantex nuclear weapons plant. Fermi America is a company cofounded by former Texas governor and energy secretary Rick Perry and his son, Griffin Perry, a cofounder and past senior advisor at Grey Rock Investment Partners. The announcement—a first press release from relative newcomer Fermi America—says the company “proudly answers President Donald J. Trump’s call to deliver global energy and AI dominance.”

There is a critical knowledge gap regarding the health consequences of exposure to radiation received gradually over time. While there is a plethora of studies on the risks of adverse outcomes from both acute and high-dose exposures, including the landmark study of atomic bomb survivors, these are not characteristic of the chronic exposure to low-dose radiation encountered in occupational and public settings. In addition, smaller cohorts have limited numbers leading to reduced statistical power.

Orano Group subsidiary Orano Med, a developer of targeted alpha therapies for oncology, inaugurated the expansion of its main research and development center located in Plano, Texas. The facility is used in the development of radiopharmaceuticals and for conducting preclinical research focused on targeted alpha therapies using lead-212, an alpha-emitting radioisotope that has shown promise in treating various types of cancer.
