Czech nuclear safety officials say domestic nuclear power plants have sufficient cooling water for both existing and new units

Droughts across parts of Europe are affecting the operation of some nuclear power plants. Due to low water levels and flow rates in the Danube River, two reactors at Romania's Cernavodă Nuclear Power Plant have been shut down, and Hungary's Paks Nuclear Power Plant also faces the risk of a complete shutdown. Štěpán Kochánek, Chairman of the Czech State Office for Nuclear Safety (SÚJB), stated that plant operators should not be allowed to continue operating units at full power when cooling water is insufficient, and that related shutdown measures are conservative actions predefined in operating procedures. Kochánek explained that reactor shutdowns are not an unusually rare operation. Unit shutdown typically involves gradually reducing reactor power, inserting control rods, and bringing fission reactions to a minimal level or complete cessation. After shutdown, the reactor still requires cooling, but the demand for cooling water volume and capacity is significantly lower than during full-power operation. He noted that this process shares similarities with planned outages such as refueling overhauls and is a standardized procedure that operators should master.

Shimane Nuclear Power Station Unit 2 scheduled inspection completion date moved up to September 16

Chugoku Electric Power Co., Inc. announced on August 5 that the schedule for the 18th periodic utility inspection of Shimane Nuclear Power Station Unit 2 has been revised, with the inspection completion date moved up from September 17, 2026 to September 16, and the power generation resumption date moved up from August 19 to August 18. Shimane Nuclear Power Station Unit 2 is a boiling water reactor unit with a rated electrical output of 820 MW. The unit was shut down on February 9, 2026 and entered its 18th periodic utility inspection. The reason for this adjustment is that, during the reactor start-up preparation work, the procurement of the nitrogen gas source used to fill the reactor containment vessel was completed earlier than planned, allowing the related work to be advanced accordingly...

South Korea Launches Emergency Safety Inspection of Nuclear Facilities Amid Heatwave

The Nuclear Safety and Security Commission (NSSC) of South Korea announced on August 5 that, due to the ongoing nationwide heatwave, it will conduct an emergency inspection of the safety status and emergency response preparedness of nuclear facilities, including nuclear power plants. The inspection was conducted via video conference, with participation from personnel of the NSSC's six regional offices, safety regulatory agencies, and Korea Hydro & Nuclear Power (KHNP). The inspection focused on the potential impact of rising seawater temperatures used for cooling nuclear power plants. The NSSC verified the performance of relevant measuring instruments and heat exchangers, and examined KHNP's on-site emergency response status and handling procedures. The design temperature limits for seawater intake at South Korea's nuclear power plants range from 31 to 36.1 degrees Celsius. Due to climate change, the risk of high seawater temperatures is gradually emerging. In 2024, seawater temperatures in the waters off all South Korean nuclear power plants, except for the area around Shin-Hanul Units 1 and 2, reached record highs.

Colorado State University produces first ultracold neutral plasma with electron temperature below 1 kelvin

Researchers at Colorado State University have, for the first time, produced an ultracold neutral plasma by combining laser cooling techniques with strong magnetic fields. Measurements show that the electron temperature in this plasma is less than 1 kelvin above absolute zero, making it one of the lowest electron temperatures ever measured in a plasma. The research was published in Physics of Plasmas. The new method proposed in the paper helps test plasma theories under more controllable experimental conditions and improve computational models of plasma behavior in extreme environments. The researchers believe this achievement could contribute to future fusion energy...

Hongyanhe Nuclear Power Plant Equipment Criticality Classification System Goes Live

Recently, the equipment criticality classification system at Hongyanhe Nuclear Power Plant was officially put into operation, marking a new stage in equipment classification management transitioning from traditional offline spreadsheet management to online systematic management, and opening a new chapter in digital management. Equipment classification is the foundation of equipment reliability management. To optimize production management and maintenance resource allocation, and to ensure the safe, stable, and economical operation of nuclear power units, nuclear power plants need to implement classified management of equipment, making plant maintenance resources more focused on critical equipment that affects the safe and stable operation of units, and optimizing equipment maintenance costs. However, the traditional equipment classification management model faces many pain points. The classification work involves 740,000 equipment functional locations, with a huge and scattered amount of data, relying on manual maintenance; the synchronization of equipment classification data with SAP and CCM system data lags behind, and the approval of the classification process relies on offline circulation, resulting in long cycles and difficult version management.

India's cumulative nuclear power generation surpasses 1 trillion units (1000 BU), NPCIL sets historic milestone

Nuclear Power Corporation of India Limited (NPCIL) announced on August 4 that cumulative nuclear power generation since the start of commercial operations has exceeded 100 billion kilowatt-hours (1000 Billion Units, equivalent to 1 trillion kWh) for the first time. The company stated that this milestone marks a significant achievement on India's path toward clean and sustainable energy, corresponding to avoiding approximately 860 million tonnes of CO₂ emissions—equivalent to approximately taking 187 million gasoline and diesel passenger vehicles off the road for a full year, or nearly the total annual greenhouse gas emissions of a single industrialized nation such as Germany or Japan. NPCIL data shows that electricity generated through nuclear power has effectively avoided substantial greenhouse gas emissions. Nuclear energy is recognized as one of the low-carbon and reliable energy sources, playing a critical role in addressing climate change...

Croatia's Krško Nuclear Power Plant Only 3.4°C Away from Shutdown Threshold

Croatian Prime Minister Andrej Plenković on August 4 dismissed concerns that the Slovenia-Croatia jointly owned Krško nuclear power plant might be forced to shut down due to excessively high Sava River water temperatures, stating that power supply is secure and the situation is under control. However, the plant is actually approaching environmental cooling limits, and due to abnormally high temperatures and declining Sava River water levels, the safety limits at the Krško nuclear power plant are nearing critical thresholds. According to environmental regulations, the daily average temperature of the river at the complete mixing point must not exceed 28 degrees Celsius, and the daily temperature increase must not exceed 3 degrees Celsius. As of August 4, the Sava River in the area was 24.6 degrees Celsius, with a daily increase of 2.6 degrees Celsius, leaving only 3.4°C before the 28°C red line and 0.4°C before the 3°C daily increase red line...
