As the U.K. government looks to finalize investment decisions for the construction of the Sizewell C nuclear power plant this summer, France’s state-owned EDF has announced plans to take a 12.5 percent stake in the project and commit up to £1.1 billion ($1.5 billion) in funding.

Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.

Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.

In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.

From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

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.
