TerraPower has begun the generic design assessment review process in the United Kingdom and created a U.K.-based subsidiary this week.
The Bellevue, Wash.-based nuclear company submitted its generic design assessment application for its Natrium reactor in October 2025. The U.K. government’s Department for Energy Security and Net Zero accepted TerraPower’s application for review in February.
With step one of the generic design assessment review process underway, TerraPower’s newly formed subsidiary TerraPower UK will serve as the operational base for the company’s U.K. activities, including engagement for the generic design assessment. TerraPower selected Ian Hudson to lead the company’s U.K. subsidiary.
Estonia’s government has adopted the Nuclear Energy and Safety Act on Wednesday, formally creating its first complete set of rules for generating nuclear power and overseeing it.
The law would establish an independent nuclear regulator, step-by-step licensing process, and operator responsibility for safety and end-of-life costs. Additionally, the law emphasizes that Estonian developers must only use proven technologies that are already in use.
The government approved the draft and sent it to the Parliament in March 2026, according to Parliament of Estonia’s press release. If the Estonian president signs off within 14 days, then it would take effect on Jan. 1, 2027.
The Nuclear Regulatory Commission has accepted Eden Radioisotopes’ application to build a medical isotope production facility in Lea County, N.M. for review, according to the agency’s Tuesday press release.
The application, submitted on May 5, proposes to build a non-power production and utilization facility that includes a 1.8-megawatt thermal non-power reactor to irradiate targets, according to a press release. It also includes a processing facility to extract the desired isotopes for medical imaging and radiotherapeutics purposes. A Federal Register notice will be published soon to open up a 30-day public comment period for the application.
“The NRC’s central role with nuclear technologies is to ensure they are developed safely and responsibly,” Executive Director of Operations Mike King said. “The agency is initiating a thorough, technical evaluation and our experts will carefully review the proposed design to ensure the project meets NRC safety standards. We will conduct an efficient and timely review focusing our efforts on what matters most for safety.”
Deep Isolation has appointed Jon Tedrick as its technology demonstration lead for the company’s demonstration program at the Deep Borehole Demonstration Center near Cameron, Texas.
As the technology demonstration lead, Tedrick will be responsible for coordinating field execution activities, assisting with engagement between project collaborators and contractors and helping with project preparation oversight at the Texas facility, according to Deep Isolation’s Wednesday press release. Prior to joining, Tedrick was the drilling project manager with Navarro Research and Engineering.
The demonstration program is designed to validate key components of the Deep Isolation’s deep borehole disposal technology under certain field conditions. The company said it plans to demonstrate the construction of a deep borehole repository using standard oil and gas drilling practices and retrieval operations using its Universal Canister System.
