Nuclear NewsNEW US collaboration to study used nuclear fuel recyclingCurio, NuScale Power, and Framatome have signed a memorandum of understanding to evaluate the recycling of used nuclear fuel. The partners will use Curio’s proprietary NuCycle technology to assess pathways for recovering materials from spent fuel. This effort aims to support future fuel fabrication, supply chain development, and commercial deployment of advanced reactors. This collaboration addresses the long-standing challenge of managing used fuel in the United States, where commercial reprocessing has been prohibited since 1977. By exploring methods to recover materials and reduce waste volumes, the companies seek to create a more integrated fuel cycle. This work aligns with recent Department of Energy initiatives aimed at developing commercially viable reprocessing technologies for the...
Nuclear NewsNEW Industry Update—August 2026August 2026 industry developments include multiple SMR design, manufacturing, and supply chain agreements across the United States, Europe, and Canada. Key activities involve new partnerships for reactor components, regulatory filings for advanced designs, and corporate acquisitions aimed at vertical integration. These moves reflect a broader trend of consolidating supply chains for modular reactor deployment. These developments highlight the ongoing transition from conceptual design to industrial-scale manufacturing for small modular and advanced reactors. By securing specialized valve suppli...
Nuclear NewsNEW Nuclear roots run deep in Atomic City, Idaho, next to hub for new reactor testingDeployable Energy recently achieved criticality for a new test reactor at the Idaho National Laboratory. This milestone marks the first sustained chain reaction for the company, which aims to develop micro reactors capable of powering 1,000 homes. The project is part of a broader effort to deploy smaller, transportable nuclear energy systems. The industry is currently shifting focus toward micro reactors intended for remote communities, military bases, and data centers. While proponents view these designs as a solution to rising energy demands, critics express concern regarding the impact of e...
Site NewsNEW Every Outage Finally Has a NameEvery Outage Finally Has a Name If you have worked an outage, you know it has a name. Nobody at the tool crib says "the spring outage at Catawba." They say C1R28 . It is on the badge, on the schedule, on the coffee cup somebody had printed.For years, right here on NukeWorker, every one of those outages was a date range and a colored bar. "Catawba 1, March 2026." Technically true. Totally soulless. That bugged me. So we went and got the names. The hunt Here is the thing nobody tells you: there is no master list. Nowhere can you download a tidy file where some kind soul has written down that Turkey Point 3's spring outage was TP3-35 and Surry 2's was EOC33 . What there is: tens of thousands of NRC inspection reports , licensee event reports, and utility letters, scanned and OCR'd and scatter...
