Six radiation monitoring posts in Kumamoto Prefecture, Japan, resumed transmission on the morning of the 30th after being interrupted by power outages caused by the earthquake

Radiation monitoring stations in Kumamoto Prefecture, Japan, have resumed operations after data interruptions caused by the earthquake. On the morning of July 30, data transmission at all monitoring stations returned to normal. The initial cause of the malfunction is believed to be power outages resulting from the earthquake, and the Nuclear Regulation Authority of Japan will conduct further investigations into the matter. A total of six radiation monitoring stations are located in Kumamoto Prefecture, distributed across Kumamoto City, Uto City, and other areas, used for real-time measurement of radiation levels in the environment. Starting around 11 p.m. on July 28, data transmission from these stations was suddenly interrupted, making it impossible to assess local radiation levels. This situation drew significant attention from relevant authorities. According to the Nuclear Regulation Authority of Japan...

US NRC Approves Oyster Creek Nuclear Power Plant License Termination Plan

The U.S. Nuclear Regulatory Commission (NRC) has approved the license termination plan for the Oyster Creek Generating Station. Located in Lacey Township, New Jersey, the plant is now more than halfway through its decommissioning and dismantlement work. With this approval, the project will proceed with the final phases of decommissioning and site restoration in accordance with the approved document. Before dismantlement of the Oyster Creek Generating Station in Lacey Township, New Jersey, Holtec International stated that the approval of the license termination plan involved coordinated efforts across multiple departments, including engineering, radiation protection, environmental services, work management, project controls, licensing, communications, and security, led by the regulatory affairs department. The Vice President of Oyster Creek Nuclear Power Plant...

Hungary's Paks Nuclear Power Plant Faces Full Shutdown Due to Record Low Danube Water Level

Affected by persistent drought and high temperatures, the water level of the Danube River at the Budapest section dropped to 23 cm (fixed datum reading, a record low), restricting cooling water intake at the Paks Nuclear Power Plant. Starting Wednesday, July 29, Unit 3 was the first to be shut down; the operator, MVM Paks Nuclear Power Plant Ltd, subsequently stated on its official website that all four units would inevitably be disconnected within the next 24 to 72 hours, with power generation coming to a complete halt. MVM explained that the existing water volume of the Danube is still sufficient to cool the reactors, but the intake pumps can no longer draw water because the riverbed is exposed and the pump inlets are too far from the water surface—an equipment failure rather than an absolute shortfall in cooling water volume. To this end, the Hungarian side deployed 4 pumping barges and 2 floating cranes near the plant as an emergency measure, but with water levels expected to continue falling, a preventive full shutdown remains unavoidable.

Progress in Russia's Khilonduevskoye Uranium Deposit Development: 3 Kilometers of Mine Workings Completed Ahead of Schedule

The mining division of Russia's Rosatom recently announced that underground mining crews completed three kilometers of mine workings ahead of schedule during the development of the Khilonduevskoye deposit. This milestone, originally planned for completion on August 10, was achieved by a team of workers from the Priargunsky Industrial Mining and Chemical Union (PIMCU), which is part of Rosatom Nedra. According to PIMCU, this mine connection will significantly optimize the ventilation system at the fourth level of the Khilonduevskoye deposit and improve the efficiency of rock block loading, laying the foundation for subsequent development work. The company's CEO, Ivan Kiselev, stated that this connection is of critical importance to the company, as it not only links two sections of the mine but also fundamentally transforms the logistics and safety of fourth-level operations.

Restart of Tomari Nuclear Power Plant Unit 3 Delayed to After End of 2027

Hokkaido Electric Power Co. announced on July 30 that the restart of Unit 3 at the Tomari Nuclear Power Plant will be significantly delayed compared to earlier expectations, with the earliest possible date being the end of 2027 or later. Previously, the company had set a target of restarting as early as possible within 2027, but due to delays in the seawall construction project and the fact that the Nuclear Regulation Authority (NRA) has not yet completed its review of the relevant design and construction plans, the timeline for the unit's return to operation remains uncertain. Hokkaido Electric Power President Susumu Saito stated at a press conference that the seawall at the Tomari plant was originally scheduled for completion in the spring of 2027, but is now expected to be finished by mid-August 2027 due to additional work such as seismic reinforcement of the wharf and liquefaction countermeasures...

Fuel unloading completed for Unit 3 of Dukovany Nuclear Power Plant

On July 30, Unit 3 of the Dukovany Nuclear Power Plant completed the unloading of reactor fuel assemblies, and the planned refueling outage has now entered its next phase. During this outage, the plant will replace part of the nuclear fuel and carry out hundreds of inspections, tests, and maintenance activities to enhance nuclear safety levels and ensure the long-term stable operation of the unit. In this outage, although the actual number of fuel assemblies to be replaced accounts for about one-fifth of the total, operators must first remove all fuel assemblies from the entire core and transfer them to the spent fuel pool. Subsequently, the reactor water level will be lowered to create conditions for maintenance of core cooling system components and inspection of some primary circuit equipment...

Rosatom says 13 small reactor pressure vessels at various production stages

Rosatom Director General Alexey Likhachev recently stated that 13 small reactor pressure vessels are currently at various production stages, and the equipment will be used for nuclear-powered icebreakers and small nuclear power plant projects. Likhachev noted that the batch includes reactor pressure vessels for the Uzbekistan nuclear power plant, which is planned to start construction in 2026. He said that the simultaneous manufacturing of 13 small reactor pressure vessels is unprecedented in the history of Russia's nuclear industry. The reactor pressure vessel is one of the core components of the primary circuit of a nuclear reactor, used to house the core and related internal structures, and withstand high temperatures and pressures during operation.

Chugoku Electric Power Submits Third Amendment to Reactor Installation Change Permit Application for Shimane Nuclear Power Plant Unit 3 to Regulatory Authority

Chugoku Electric Power Co., Inc. announced on July 29 that it had submitted the third amendment to the reactor installation change permit application for Unit 3 of the Shimane Nuclear Power Plant to the Nuclear Regulation Authority (NRA) on the same day. The company stated that this amendment adjusts the application content for related equipment at the plant based on previous review findings. This includes reclassifying certain equipment already installed for Unit 2, such as the emergency response center, for shared use between Unit 2 and Unit 3. According to reports, Chugoku Electric Power had previously submitted two amendments to the reactor installation change permit application for Unit 3 of the Shimane Nuclear Power Plant, on December 22, 2021, and June 29, 2022, respectively.
