Nuclear NewsNEW Front-end nuclear fuel supply cooperation: Turning allied interdependence into strategic advantageThe Sapporo Five nations are coordinating front-end nuclear fuel cycle investments to reduce reliance on Russian enrichment services. This multilateral strategy aims to integrate mining, conversion, enrichment, and fabrication capabilities across allied countries. The initiative seeks to create a resilient, competitive supply chain capable of supporting global nuclear power expansion. Western nuclear operators face supply vulnerabilities as they transition away from Russian-controlled enrichment and conversion services. By treating allied capabilities as a single market, these nations intend to avoid redundant infrastructure while accelerating the qualification of new fuel forms. This cooperation is necessary to meet the rising demand for baseload power from data centers and climate-driven...
Nuclear NewsNEW What Does It Take to Reopen a Nuclear Power Plant?Efforts to restart the shuttered Palisades nuclear plant in Michigan have faced significant delays due to unexpected equipment corrosion, supply chain issues, and the need for extensive repairs. Holtec International, the plant operator, encountered these challenges while attempting to recommission the facility, which had been slated for permanent closure in 2022. The difficulties at Palisades highlight the technical and financial complexities of reviving aging nuclear infrastructure compared to maintaining active facilities.

Site NewsEvery 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...
