Automatic Shutdown of Unit 3 at Oi Nuclear Power Plant During Operation; Kansai Electric Power to Investigate Cause from the 12th

Unit 3 of the Oi Nuclear Power Plant in Fukui Prefecture, Japan, experienced an automatic shutdown during operation in the early hours of the 9th. Operator Kansai Electric Power stated that the fault is related to an internal abnormality in the generator and plans to formally begin a cause investigation from the 12th. Currently, there is no clear timeline for when the unit can resume operation. According to reports, an alarm related to loss of magnetic field occurred inside the generator used for power generation at the time of the incident, after which the generator stopped, and the reactor in operation also automatically shut down. On the 10th, Kansai Electric Power visited the Fukui Prefectural Government to apologize for the fault and report on subsequent response measures. Yuichiro Sakamoto, head of the Fukui Prefecture Disaster Prevention and Safety Division, pointed out that following a steam leak fault at Mihama Nuclear Power Plant Unit 3 in May this year, an unexpected emergency shutdown of a reactor in operation occurring within a short period may undermine public trust in nuclear safety. Local government authorities have demanded that the operator promptly identify the cause and implement measures to prevent similar issues from recurring.

U.S. nuclear energy company Holtec advances on two fronts this week: decommissioning aging nuclear plants and positioning small reactors in the southern U.S.

U.S. nuclear energy company Holtec recently announced two significant developments, reflecting the dual trend in the current nuclear power industry of retiring existing capacity while expanding new capacity. On one hand, the U.S. Nuclear Regulatory Commission approved the license termination plan for the Oyster Creek nuclear power plant, moving the decommissioning process of this veteran commercial nuclear facility in New Jersey, which began operations in 1969, past a key regulatory milestone. On the other hand, Holtec announced a partnership with Entergy and Hyundai Engineering & Construction to evaluate potential sites for deploying new reactors in the southern Gulf Coast region of the United States. The Oyster Creek plant ceased power generation in 2018 and was subsequently taken over by Holtec for decommissioning. The recently approved license termination plan...

"Triple-Arrow Assault" Confirms a Cosmic "Natural Accelerator" Ejecting Protons at Energies 100 Times That of the Large Hadron Collider

Astronomers, using three observation facilities operating in different wavelength bands, have confirmed a mysterious celestial body in the direction of the Aquila constellation in the Milky Way as a natural cosmic accelerator. This object is continuously ejecting high-speed particles with energies far exceeding any man-made accelerator on Earth, equivalent to 100 times that of the Large Hadron Collider (LHC). This discovery provides key clues for tracing the origin of the highest-energy cosmic rays in the Milky Way, and the research findings were published in the latest issue of The Astrophysical Journal. A size comparison between the gamma-ray source (large circle) and the Moon (small circle). Image credit: The Astrophysical Journal.

Linn County, Iowa, rejects rezoning application for data center site near nuclear power plant

The Linn County Board of Supervisors in Iowa said Monday it will not proceed with amendments to the EU-2 zoning district. This decision means that large data centers will not be permitted to be built near nuclear facilities through this zoning rule for the time being. The current EU-2 zoning primarily allows for nuclear power generation facilities, nuclear waste storage facilities, and natural gas power generation facilities, and does not list large data centers as permitted uses. The zoning adjustment drew attention due to the potential restart of the Duane Arnold Energy Center near Palo. If the nuclear facility were to resume operations, it could provide a stable power source for energy-intensive data centers, prompting interest from data center companies in surrounding...

International Team Measures Niobium-94 Neutron Reactions, Explaining Anomalous Molybdenum-94 Abundance in the Solar System

An international team of physicists has, for the first time, conducted a comprehensive study of the interactions between neutrons and the niobium-94 isotope. The findings have been published in Physical Review Letters. The study suggests that the elevated abundance of molybdenum-94 in the primordial material of the solar system can be explained by a series of neutron-involving nuclear reaction processes inside old stars, without requiring the introduction of previously unknown special formation mechanisms. The research was led by Alberto Mengoni, a researcher at the Italian National Institute for Nuclear Physics. The team conducted experiments using the n_TOF facility at CERN, focusing on tracking the interactions between neutrons and niobium-94 atoms. The n_TOF facility is used to...
