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.

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.

In an article just published by the Taking Measure blog of the National Institute of Standards and Technology, Stephen Russek—who leads the Imaging Physics Project in the Magnetic Imaging Group at NIST and codirects the MRI Biomarker Measurement Service—describes his team’s work using phantom stand-ins for human tissue.

This spring, the Department of Energy’s Office of Environmental Management announced that it had achieved a major milestone by completing commissioning of the Safety Significant Confinement Ventilation System (SSCVS) facility—a new, state-of-the-art, large-scale ventilation system at the Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic (TRU) waste in New Mexico.

Centrus Energy has secured a contract extension from the Department of Energy to continue—for one year—its ongoing high-assay low-enriched uranium (HALEU) production at the American Centrifuge Plant in Piketon, Ohio, at an annual rate of 900 kilograms of HALEU UF6. That's the same amount of HALEU—900 kg—that the company today announced it has delivered to the DOE, completing Phase II of its contract. According to Centrus, the contract extension, which allows the company to begin Phase III, is valued at about $110 million through June 30, 2026.

U.S.-based private capital group Apollo Global has committed £4.5 billion ($6.13 billion) in financing to EDF Energy, primarily to support the U.K.’s Hinkley Point C station. The move addresses funding needs left unmet since China General Nuclear Power Corporation—which originally planned to pay for one-third of the project—exited in 2023 amid U.K. government efforts to reduce Chinese involvement.

Plastic waste is polluting the oceans and entering the human body in the form of microplastics. According to the United Nations, without immediate action the amount of plastic finding a way into the oceans each year could reach 37 million metric tons by 2040, becoming a threat to marine and human life.
