Nuclear NewsNEW Nuclear reactor simulations advance with quantum particle transport breakthroughNuclear reactor simulations advance with new quantum transport method Quantum X Labs has developed an algorithm that encodes complex physical geometries into quantum states for reactor modeling. By reducing the computational overhead required to define material boundaries, the method allows quantum processors to dedicate more capacity to simulating neutron and photon transport. This approach aims to improve the accuracy of three-dimensional nuclear system simulations that currently exceed the capabilities of standard supercomputing hardware. Quantum X Labs translates jagged physical shapes int...
Nuclear NewsNEW US closes in on resurrecting shuttered nuclear power plants with key findingsUS closes in on resurrecting dormant nuclear plants after key findings Federal regulators issued draft environmental reviews concluding that restarting the shuttered Duane Arnold Energy Center and Christopher M. Crane Clean Energy Center will cause no significant environmental harm. These assessments utilize technical protocols established during the ongoing restart process at the Palisades Nuclear Plant. This framework provides a standardized path for returning decommissioned facilities to the power grid by satisfying federal environmental and safety requirements. Federal agencies are paving...
Nuclear NewsNEW US maritime nuclear energy company raises USD50 millionBluecore Energy secured 50 million dollars in seed financing to advance the development of its 10 MWe floating small modular reactor systems. The company is currently testing components at its Port of Long Beach headquarters while coordinating with the Nuclear Regulatory Commission and the US Coast Guard. These funds will support ongoing engineering, hardware testing, and regulatory efforts for the company's maritime nuclear power technology. Bluecore Energy, a developer of small modular, water-cooled reactors designed to operate aboard floating barges, has announced the close of a USD50 milli...
Nuclear NewsNEW US Department of Energy closes loan for Duane Arnold restartThe Department of Energy finalized a 1.9 billion dollar loan to NextEra Energy to support the restart of the Duane Arnold Energy Center in Iowa. The project aims to return 615 MWe of capacity to the grid by 2029 to meet rising electricity demand. NextEra Energy is currently conducting engineering evaluations and regulatory reviews to bring the single-unit boiling water reactor back into service. The US Department of Energy's Office of Energy Dominance Financing has closed a loan of up to USD1.9 billion to NextEra Energy to help finance the restart of the Duane Arnold Energy Center, taking the...
Nuclear NewsNEW NRC finds radiation safety lapses during Palisades restart workSome pretty impressive airborne activity numbers to say the least. Sounds like some remedial RP training may be needed.
Nuclear NewsNEW Fresh record set for nuclear generation in 2025Global nuclear electricity generation reached 2,702 TWh in 2025, surpassing the previous year's record. The global fleet maintained an average capacity factor of 83.7 percent, while construction began on eleven new reactors. To meet international goals of tripling capacity by 2050, the World Nuclear Association recommends that governments prioritize supply chain strengthening, regulatory streamlining, and the development of a skilled workforce to support sustained deployment. Nuclear reactors worldwide generated 2,702 TWh of electricity in 2025, beating the previous year's record of 2,667 TWh,...
Outage NewsNEW Davis-Besse trips offline, unscheduled outage underwayDavis-Besse began an unscheduled forced short outage on 2026-09-08. This event ended the unit's unscheduled-outage-free streak at 386 days. This is the first forced outage for the 894-MW Babcock and Wilcox PWR in 2026, matching the total count for all of 2025. Energy Harbor Nuclear Generation operates this unit along with three other U.S. nuclear units. Across the industry, 94 units are currently operating at a 95.4 percent capacity factor. Two units are currently in refueling outages, while Davis-Besse and Dresden 2 are the only two units in unscheduled outages at this time. OAK HARBOR, OH. An unscheduled outage at Davis-Besse began on Sep 8, 2026 . 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 unsc...
Outage NewsNEW North Anna 2 begins Fall 2026 refueling outageNorth Anna 2 began its scheduled refueling outage on September 6, 2026, two days earlier than the original plan. The unit entered this maintenance period after completing 95 percent of its typical 548-day operating cycle and maintaining an unscheduled-outage-free streak of 987 days. The unit is a 944-MW Westinghouse 3-loop PWR operated by Virginia Electric and Power, which manages three other nuclear units in the United States. This refueling follows a prior cycle that achieved a 90 percent capacity factor. The outage duration is scheduled for 36 days, compared to the 43-day average recorded a...
Outage NewsNEW McGuire 1 begins Fall 2026 refueling outageMcGuire 1 began its scheduled refueling outage on September 5, 2026, meeting the planned start date exactly. The unit entered this maintenance period after completing 92 percent of its typical 547-day operating cycle and maintaining an unscheduled-outage-free streak of 246 days. The 1,158-MW Westinghouse 4-loop PWR has a historical average refuel duration of 37.6 days across 18 prior events, with a maximum duration of 78 days recorded in 2007. Duke Energy Carolinas operates this unit along with six other U.S. nuclear units. Across the current fleet of 94 units, the industry capacity factor is...

History & TriviaThe Hiroshima Atomic Blast Forged a Metal Never Seen Before on EarthGeologists led by the University of Florence have identified a previously unknown iron-chromium alloy within microscopic fallout debris from the 1945 Hiroshima atomic bombing. The 10-micrometer grain exhibits a complex, highly ordered cubic crystal structure that formed due to the extreme temperatures and rapid cooling rates of the nuclear fireball. This discovery highlights that nuclear blast debris contains a unique library of metastable materials that are difficult to replicate in laboratory settings. For the nuclear industry, these findings demonstrate that fallout particles serve as a phy...
