A report just released by Idaho National Laboratory reviews decades of radiation protection standards and research on the health effects of low-dose radiation and recommends that the current U.S. annual occupational dose limit of 5,000 mrem be maintained without applying ALARA—the “as low as reasonably achievable” regulatory concept first introduced in 1971—below that threshold.

Noting that epidemiological studies “have consistently failed to demonstrate statistically significant health effects at doses below 10,000 mrem delivered at low dose rates,” the report also recommends “future consideration of increasing this limit to 10,000 mrem/year with appropriate cumulative-dose constraints.”

The United States has tight new deadlines—18 months, max—for licensing commercial reactor designs. The Department of Energy is marshaling the nuclear expertise and high-performance computing assets of its national laboratories, in partnership with private tech companies, to develop generative AI tools and large-scale simulations that could help get nuclear reactor designs through the Nuclear Regulatory Commission’s licensing process—or the DOE’s own reactor pilot program. “Accelerate” and “streamline” are the verbs of choice in recent announcements from Oak Ridge National Laboratory and Idaho National Laboratory, as they describe plans with Atomic Canyon, Microsoft, and Amazon.

At the end of his July 15 speech at the inaugural Pennsylvania Energy and Innovation Summit, President Trump promised that “a lot more [was] going to be announced in the coming week” for the energy and AI sectors.

In back-to-back press releases, Oklo recently announced two new partnerships that seek to advance the deployment of its commercial power reactors in the data center market.

These partnerships, one with Ohio-based Vertiv Holdings and one with Colorado-based Liberty Energy, continue Oklo’s trend in working to position their Aurora powerhouse as a key part of the energy solution for powering the AI boom.

Leaders from private companies, government, and national laboratories gathered at Argonne National Laboratory on July 17 and 18 for an exclusive AI x Nuclear Energy Executive Summit that the Department of Energy called a first-of-its-kind forum to “align next-generation nuclear systems with the needs of digital infrastructure.”

Teams from the Department of Energy’s Offices of Environmental Management and Nuclear Energy recently collaborated on the Road Ready Demonstration Project by testing new equipment to seal spent nuclear fuel into a safe and transportable system for future shipments out of Idaho.

The Idaho National Laboratory has announced that it will collaborate with Microsoft on the use of artificial intelligence technologies to streamline the nuclear permitting and licensing application process. Using Microsoft’s Azure cloud computing platform, INL will generate the engineering and safety analysis reports that are required to be submitted for construction permits and operating licenses for nuclear power plants.

Following the signing of a new agreement, Kiewit Nuclear Solutions, a subsidiary of Kiewit Corporation, is officially the lead constructor for Oklo’s first commercial Aurora powerhouse, which will be built at Idaho National Laboratory.

An article in the OECD Nuclear Energy Agency’s July news bulletin noted that a first test has been completed for the High Burnup Experiments in Reactivity Initiated Accident (HERA) project. The project aim is to understand the performance of light water reactor fuel at high burnup under reactivity-initiated accidents (RIA).

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.

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.

Details of the plan to test new reactor concepts under the Department of Energy’s authority but outside national laboratory boundaries—first outlined in one of the four executive orders on nuclear energy released on May 23—were just released in a request for applications issued by the DOE.

Idaho National Laboratory this week signed a memorandum of understanding with the Missouri University of Science and Technology that highlights the joint commitment of the institutions to the Strategic Understanding for Premier Education and Research (SUPER) initiative.

At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

The National Reactor Innovation Center is accepting applications from developers ready to take a fueled microreactor to criticality inside the former Experimental Breeder Reactor-II containment building at Idaho National Laboratory, now repurposed as DOME—a microreactor test bed. According to a Department of Energy announcement, DOME will be ready to receive the first experimental reactor in the fall of 2026, with testing likely to begin in 2027.

An agreement signed by the state of Idaho and the U.S. Department of Energy will open the way for a single cask of high-burnup spent nuclear fuel to be shipped from Dominion Energy’s North Anna nuclear power plant in Virgina to Idaho National Laboratory for research purposes.

Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.

On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

New ultrasonic testing equipment being used by the Department of Energy’s Idaho Cleanup Project (ICP) to confirm the integrity of thousands of legacy waste drums is saving taxpayers tens of millions of dollars, the DOE’s Office of Environmental Management announced.

The technology allows ICP personnel to inspect the thickness transuranic waste drums held in storage at the DOE’s Idaho National Laboratory Site, ensuring they meet Department of Transportation minimum thickness requirements to be shipped for disposal at the Waste Isolation Pilot Plant in New Mexico. According to DOE-EM, if drums meet the DOT thickness requirements, they can be loaded directly into shipping casks without the need for an expensive overpack container, leading to a minimum cost savings of $26 million.
