Rising River Water Temperatures in Europe Constrain Nuclear Power Operations, Poland's First Nuclear Power Plant Turns to Baltic Sea for Cooling Water

Persistent high temperatures, droughts, and low river water levels across Europe are turning nuclear power plant cooling issues from a purely engineering topic into a real risk affecting the stability of electricity supply. Experience in countries such as France and Switzerland shows that when river water temperatures are too high or flow rates are insufficient, nuclear power plants—even with generating capacity available—may be forced to reduce output or temporarily shut down due to environmental restrictions. In 2022, France's nuclear power generation fell by 22% year-on-year, and during recent summer heatwaves, rising water temperatures in rivers such as the Seine and the Rhône have repeatedly led to restrictions on related units. The core of this issue is not just whether there is enough water, but also whether the water is cold enough. Traditional river-dependent cooling systems...

International Team Determines Critical Safety Parameter Ranges for Magnetic Liquid Cooling Systems

South Ural State University (SUSU) recently announced that researchers from its Polytechnic Institute, in collaboration with colleagues from Moscow and Baghdad, have determined the safe and unsafe ranges of the Hartmann number and Brinkman number in magnetic liquid cooling systems. Based on this, they developed a computer program to optimize the operation of high-power heat exchangers in devices such as supercomputers and nuclear reactors. According to the introduction, this research focuses on two key parameters in magnetohydrodynamics: the Hartmann number characterizes the resistance exerted by a magnetic field on fluid motion, while the Brinkman number reflects the internal heat generated by the fluid due to viscous effects and electrical resistance. The researchers noted that under specific conditions, a strong magnetic field does not necessarily...

Europe's High Temperatures and Droughts Impact Nuclear Power Operations, Ukrainian Expert Says Climate Adaptation Tied to Energy Independence

Recent prolonged high temperatures, droughts, and falling river levels across Europe have put pressure on the operation of some nuclear power plants that rely on river water for cooling. Nuclear facilities in France, Hungary, Romania, and Slovenia have successively experienced power reductions or shutdowns, forcing some countries to ease supply pressure through electricity imports and adjusted consumption arrangements. Katie Huff, a professor of nuclear engineering at the University of Wisconsin-Madison, stated that the impact of climate change on nuclear power operations is mainly reflected in two aspects: first, droughts lower river levels, making it difficult for plants to obtain sufficient cooling water; second, when air and water temperatures are high, nuclear plants face stricter restrictions on discharging warm water into rivers to avoid further affecting the aquatic environment.

Rosatom Says Russian Nuclear Plants Operate Stably During Summer Heat

In response to recent operational pressures faced by foreign nuclear power plants due to high temperatures and low water levels, Alexey Likhachev, CEO of Rosatom, stated that Russian nuclear power plants are operating normally during the summer peak electricity demand period, with stable power generation. Likhachev said that hot weather does require nuclear plant operators to pay more attention to the condition of cooling systems, but for Russian nuclear plants, this is a normal seasonal factor. Russian nuclear power plants have incorporated significant climate fluctuations, including extreme weather scenarios, into their design and operational phases. He stated that Rosatom has experience in...

Russian nuclear power plants generate 129.6 billion kWh of electricity this year

Alexey Likhachev, CEO of Rosatom, recently stated that since the beginning of this year, Russian nuclear power plants have generated a cumulative total of 129.6 billion kWh of electricity, exceeding the target set by the Federal Antimonopoly Service of the Russian Federation by 7.8%. Likhachev noted that Russia is currently in its summer peak electricity consumption period, and nuclear power plants across the country are operating normally overall, with stable power generation and all safety requirements being met. He stated that hot weather does require operating entities to pay greater attention to cooling and heat reduction measures, but this is a seasonal factor that must be addressed in nuclear power plant operations. He pointed out that Russian nuclear power plants have fully considered different climatic conditions during their design and operation phases...

Bulgarian Energy Minister to Inspect Unit Operations at Kozloduy Nuclear Power Plant

Bulgaria's Ministry of Energy announced on August 3 that Energy Minister Iva Petrova will visit the Kozloduy Nuclear Power Plant on August 4. Experts from the Ministry of Energy, along with representatives of the management of Bulgarian Energy Holding (BEH) and the Electricity System Operator (ESO), will accompany her. According to the Bulgarian Ministry of Energy, the visit will focus on understanding the current operational status of Units 5 and 6 at the Kozloduy Nuclear Power Plant, assessing the impact of the abnormally low Danube River water level on plant operations, and reviewing measures taken by the Ministry to ensure the security of Bulgaria's electricity system. On August 2, the Bulgarian Ministry of Energy stated that despite the Danube River water level dropping to a historic low, the two nuclear units at the Kozloduy Nuclear Power Plant...
