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.

The University of Michigan’s Department of Nuclear Engineering and Radiological Sciences (NERS) has published a summary of a study on nuclear microreactors and machine learning (ML) that was conducted by researchers from NERS and Idaho National Laboratory. The full paper, “Nuclear Microreactor Transient and Load-Following Control with Deep Reinforcement Learning,” was featured in the July issue of Energy Conversion and Management: X.

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.

The Department of Energy said it anticipated delivering a research cask of high-burnup spent nuclear fuel from Dominion Energy’s North Anna nuclear power plant in Virginia to Idaho National Laboratory by fall 2027. The planned shipment is part of the High Burnup Dry Storage Research Project being conducted by the DOE with the Electric Power Research Institute.

As preparations continue, the DOE said it is working closely with federal agencies as well as tribal and state governments along potential transportation routes to ensure safety, transparency, and readiness every step of the way.

Watch the DOE’s latest video outlining the project here.

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.

Work crews at Idaho National Laboratory have transferred 40 spent nuclear fuel canisters into long-term storage vaults, the Department of Energy’s Office of Environmental Management has reported.

Uranium provider Cameco has calculated an end-of-June spot price of $78.50 for uranium—a substantial jump from $71.55 the previous month. Cameco continues to list a long-term price of $80.00, a price that has remained unchanged since February.

The Wall Street Journal recently reviewed the status of nuclear energy in the United States, with a focus on how the U.S. nuclear industry can meet President Donald Trump’s executive orders (EOs) calling for nuclear power generation to quadruple within the next 25 years.

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.

Applications are now open for the summer 2025 testing period for the American Nuclear Society’s Certified Nuclear Professional (CNP) exam. Applications are being accepted through July 25, and only three testing sessions are offered per year, so it is important to apply soon.

The test will be administered from August 12 through September 9. To check eligibility and schedule your exam, click here.

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.

The Department of Energy’s Argonne National Laboratory will collaborate with Wisconsin-based fusion technology company Shine to design new chemical processes for separating valuable materials from used nuclear fuel.

Three authorities on health physics have written a response to President Trump’s Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission.”

Published June 27 on Substack, “Radiation Protection Policy in a Nuclear Era: Recommendations from Health Physicists in Response to EO 14300” was written by Emily A. Caffrey, assistant professor and director of the Health Physics Program at the University of Alabama–Birmingham; Amir A. Bahadori, associate professor at Kansas State University; and Shaheen A. Dewji, assistant professor at the Georgia Institute of Technology.

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.
