Repeated Power Outages at Zaporizhzhia Nuclear Power Plant Raise Concerns over Equipment Aging and Safety Risks

Repeated Power Outages at Zaporizhzhia Nuclear Power Plant Raise Concerns over Equipment Aging and Safety Risks

August 13 news, the issue of repeated interruptions to the external power supply at the Zaporizhzhia Nuclear Power Plant continues to draw attention. Relevant data shows that since February 2022, the plant has experienced 26 power outages, 14 of which occurred in the first 8 months of 2026. The Zaporizhzhia Nuclear Power Plant is the largest nuclear power plant in Europe. Once the external power supply is interrupted, the plant must switch to backup power to maintain the operation of essential safety systems. Frequent switching of power supply modes not only increases operational pressure but also poses additional risks to nuclear safety and radiation safety. Relevant parties have stated that signs of equipment aging at the Zaporizhzhia Nuclear Power Plant are intensifying, with the condition of diesel generator sets being particularly concerning. The backup diesel generator sets are generally...

SLAC team observes progressive melting of copper under extreme heat in real time

SLAC team observes progressive melting of copper under extreme heat in real time

2026-08-15

Researchers at the SLAC National Accelerator Laboratory, under the U.S. Department of Energy, and their collaborators used the Mega-electron-volt Ultrafast Electron Diffraction (MeV-UED) facility to observe in real time the melting process of copper atoms under extreme temperatures. The study was published in Nature Communications. Future fusion power plants will need to replicate fusion reactions that occur inside stars here on Earth. The core plasma can reach temperatures of hundreds of millions of degrees Celsius, while surrounding structural materials must withstand sudden, intense thermal shocks. Copper and its alloys, owing to their excellent thermal conductivity, are considered capable of serving as "heat sinks" in fusion systems...

ITER Tokamak Advances Assembly in France, Fusion Experiment Targets 150 Million Degree Celsius Plasma

ITER Tokamak Advances Assembly in France, Fusion Experiment Targets 150 Million Degree Celsius Plasma

2026-08-14

The ITER tokamak being assembled in southern France is one of the most closely watched large-scale experimental devices in global nuclear fusion research. The machine weighs approximately 23,000 tonnes in total and adopts a donut-shaped toroidal structure, using strong magnetic fields to confine high-temperature plasma, with the goal of replicating on Earth the conditions for fusion reactions that occur inside stars. Its plasma volume is approximately 830 cubic meters, far exceeding previous tokamak devices, and it is therefore expected to validate the key physics and engineering technologies required for future commercial fusion reactors. ITER adopts the toroidal tokamak structure because charged particles can move along toroidal paths under strong magnetic fields, thereby minimizing direct contact with the device's inner walls...

Dong Baotong, Director of the National Nuclear Safety Administration: China's nuclear safety level remains among the top internationally, and during the "15th Five-Year Plan" period, the number of operating nuclear power units in China will rank first in the world

2026-08-13

The State Council Information Office held a series of press conferences on August 13 themed "Starting the '15th Five-Year Plan' with a Strong Beginning," introducing the progress of comprehensively advancing the construction of a Beautiful China. Dong Baotong, Vice Minister of Ecology and Environment and Director of the National Nuclear Safety Administration, stated at the conference that ecological environment safety encompasses several key aspects, including ecological security, nuclear safety, and environmental risk prevention and control. The Ministry of Ecology and Environment serves as the lead coordinating body for both the national ecological security work coordination mechanism and the nuclear safety work coordination mechanism. Over the years, together with relevant departments, we have actively responded to various risks and challenges, effectively safeguarding the bottom line of ecological environment safety. Among these, in the area of nuclear safety, we have consolidated the primary responsibility of nuclear facility operators...

Russia to Conduct Comparative Measurements in Radiation Monitoring and Individual Dose Monitoring

In September, NIIEFA (D.V. Efremov Scientific Research Institute of Electrophysical Apparatus), a subsidiary of Rosatom, will jointly conduct comparative measurements in the fields of radiation monitoring (RM) and individual dose monitoring (IDM) with Ritverts JSC and the A.M. Nikiforov All-Russian Center for Emergency and Radiation Medicine. The work will be carried out under the supervision and support of experts from the D.I. Mendeleev All-Russian Research Institute for Metrology. The focus of these comparative measurements is to verify the accuracy, reliability, and consistency of measurement results obtained by different radiation safety monitoring methods and equipment. Through unified comparison, the performance of various instruments in workplace radiation level assessment, surface contamination monitoring, and individual exposure dose recording can be further confirmed, thereby enhancing the credibility of final radiation dose assessments.

Philippine Steel Plant in Davao Raided: Radioactive Isotopes Detected in Finished Rebar and Multiple Materials at the Facility

On August 14, Philippine authorities conducted a raid on Davao Mighty Steel Corp., a steel manufacturing plant located in Barangay Ilang, Bunawan District, Davao City. The operation followed an investigation launched by the National Bureau of Investigation (NBI) after receiving reports that the company was involved in the production and sale of substandard steel rebar, with the scope of the investigation subsequently expanding after radioactive isotopes were detected in commercially sold DMS rebar. The operation was led by the National Bureau of Investigation, with the participation of the Presidential Anti-Organized Crime Commission (PAOCC), and was supported by the Philippine Nuclear Research Institute (PNRI), the Philippine Air Force, the Philippine Coast Guard's Chemical, Biological, Radiological and Nuclear emergency response units, the Coast Guard Special Operations Group, and the Army's 10th Infantry Division.

Long-term radiation environment at Kola NPP remains under control: gamma dose rates within natural background levels, 15 permanent observation stations operating since 1972

Long-term monitoring results from the external radiation monitoring group at Russia's Kola Nuclear Power Plant show that gamma radiation dose rates around the plant site have consistently remained within natural background radiation levels, with radionuclide concentrations matching background values, indicating a sound radiation environment with no differences from surrounding areas. The station's radiation safety department collects surface water samples from the discharge canal monthly, with monitoring coverage encompassing all elements including the atmosphere, snow cover, bottom sediments, food products, algae, berries, mushrooms, and caged fish. The monitoring architecture consists of two tiers: 15 permanent environmental observation stations have been in continuous operation since before the commissioning of the first reactor unit in 1972; 13 ASKRO automated radiation environment monitoring system stations provide real-time ground-level gamma dose rate data, which is transmitted directly to the Rosenergoatom crisis center and integrated into the national unified radiation monitoring network. Approximately 200,000 cubic meters of air are drawn weekly through air filtration units to capture radionuclides, with volumetric activity of radioactive iodine also measured. A mobile radiological laboratory performs on-site spectrometric analysis. Annually, about 1,200 environmental samples are collected from around the plant site and delivered to the Polyarnye Zori laboratory, where well water samples analyzed by Canberra spectrometers yield "zero nuclide" results, with samples retained for one year for potential re-analysis. Biological samples are processed using the ashing method, and instrument sensitivity is sometimes insufficient to even detect any signal from the plant's impact.
