Nuclear NewsNEW A startup wants to build a massive nuclear-powered data center on public land in UtahStartup Valar Atomics submitted a formal proposal to the Bureau of Land Management to construct a massive power and data facility in Utah. Project Beehive would combine 456 small nuclear reactors with data centers, fuel production, and waste storage across more than 9,000 acres of public land. The project highlights a new wave of commercial nuclear ventures relying on streamlined regulatory pathways and federal support to deploy microreactors. Producing over nine gigawatts of power, the development aims to test phased mass production of small units, raising questions among local groups regarding public land use and environmental oversight. Valar Atomics wants to place over 450 reactors on more than 9,500 acres in Utah to power a huge data center project. A Valar Atomics microreactor is see...
Nuclear NewsNEW Second part of construction permit application submitted for SMRs at PalisadesHoltec International submitted the Preliminary Safety Analysis Report to the US Nuclear Regulatory Commission for two planned SMR-300 reactors at the Palisades site in Michigan. This filing completes the second phase of the construction permit application process for the Pioneer 1 and 2 units. The project aims to bring the new small modular reactors online by the early 2030s alongside the site's existing closed plant infrastructure. Holtec has submitted the Preliminary Safety Analysis Report to the US Nuclear Regulatory Commission for two small modular reactor units at the Palisades Energy Cen...
Nuclear NewsNEW Heat-only method makes critical alloys tougher for nuclear fusion reactors and jet enginesHeat method makes alloys tougher for fusion reactors and jet engines Researchers at the University of Birmingham developed a heat treatment method called Precipitation Induced Recrystallisation to refine alloy grain structures without mechanical force. The technique uses controlled thermal stress to generate internal pressure, shrinking grain sizes significantly in tested titanium alloys. This process provides a reliable way to manufacture durable components for extreme environments like fusion reactors and jet engines. The new PIX technique uses heat treatment to make tungsten and titanium al...
Outage NewsNEW Susquehanna 1 trips offline, unscheduled outage underwaySusquehanna 1 began a forced short unscheduled outage on September 29, 2026. The event ended the 1,247-MW General Electric BWR/4 unit's unscheduled outage-free streak at 317 days. Operator TalenEnergy Susquehanna, which operates one other U.S. nuclear unit, logged one forced outage so far in 2026 compared to two in all of 2025. The plant has been in commercial operation since 1983. Across the broader fleet today, 94 units operate at an 88.9 capacity factor, with nine reactors in refueling and one in unscheduled outages. BERWICK, PA. Susquehanna 1 dropped offline on Sep 29, 2026 , beginning an unscheduled outage. The NRC has not yet issued an event notification for this trip; a follow-up reply will be posted here if one is filed. This is the first unscheduled outage of 2026 for the unit, wh...
Outage NewsNEW Cooper begins Fall 2026 refueling outageCooper began a routine refueling outage on September 28, 2026, starting two days later than its scheduled September 26 start date. The 772-megawatt General Electric boiling water reactor entered the refueling window after running about 100 percent of its typical 647-day operating cycle. Operated by Nebraska Public Power District with commercial operation since 1974, the plant maintained a 1379-day unscheduled-outage-free streak going into the event. The unit posted a 99.4 percent capacity factor during its prior cycle in 2025. Across the United States fleet, 94 units operated at a 90.1 percent...
Outage NewsNEW Byron 2 begins Fall 2026 refueling outageByron Unit 2 began a scheduled refueling outage on September 28, 2026, starting precisely on its planned date. The 1,136-MW Westinghouse four-loop pressurized water reactor entered the fall maintenance period following a 3637-day unscheduled-outage-free streak. Operated by Constellation Nuclear, the unit had run about 94 percent of its typical 547-day operating cycle and posted a 93.9 percent capacity factor during the 2025 prior cycle. Across the broader U.S. fleet, 94 units operated at a 90.1 percent capacity factor with nine units in refueling. BYRON, IL. Byron 2 entered a refueling outage...
History & TriviaNEW Fewer Than 10 American Veterans Who Saw Hiroshima and Nagasaki Are Still Alive. Their Stories Are DiFewer than 10 American service members who entered Hiroshima and Nagasaki as occupation troops in 1945 remain alive. These aging veterans are the last direct witnesses to the immediate human and structural devastation caused by the first wartime use of atomic weapons. For decades, government secrecy orders prevented these personnel from discussing their radiation exposure and observations. Preserving their firsthand accounts provides valuable historical documentation regarding the long-term health effects of radiation on military personnel and the realities of nuclear warfare. American occupation troops witnessed Hiroshima and Nagasaki weeks after the atomic bombs. Fewer than 10 are believed to remain alive. Less than 10 American veterans who saw the Japanese cities after 1945 bombings are...

History & TriviaThis Hidden City In Tennessee Held One Of The World’s Most Closely-Guarded SecretsOak Ridge, Tennessee transformed rapidly from a rural farming town into a massive, classified site for the Manhattan Project during World War II. Thousands of workers labored in secrecy to produce material for the atomic weapons that ultimately brought an end to the global conflict. The historic site established strict security protocols and massive industrial infrastructure that laid the groundwork for modern nuclear research facilities. Today, the location preserves its wartime heritage while continuing to contribute to advancements in science, technology, and energy research within the nucl...
