When heat slows down the atomic current

The article discusses how extreme heat affects nuclear power plant operations in Hungary and France, impacting electricity supply and market stability. In Hungary, low water levels in the Danube threaten the operation of its sole nuclear power plant at Paks, which normally provides 40% of the country’s electricity. In France, where nuclear energy accounts for a significant portion of the energy mix, heatwaves have caused temporary reductions in reactor output, affecting both domestic consumption and cross-border electricity exports. While annual production losses due to high temperatures are relatively small, under 1% per year, the short-term impacts during heatwaves can be substantial, reducing available capacity by up to 8 gigawatts. Despite these challenges, France has maintained sufficient reserves and remained a net electricity exporter during recent heatwaves. The article highlights the vulnerability of nuclear plants to environmental conditions and the broader implications for energy security and pricing.

Extreme heat has placed pressure on Europe’s nuclear energy infrastructure, exposing vulnerabilities in a sector long considered a cornerstone of the continent’s power supply. The situation has been particularly acute in France, where prolonged heatwaves have forced the temporary shutdown of multiple nuclear reactors due to cooling constraints. As of late July 2026, 13 of France’s 57 nuclear reactors were offline, representing a 20.4 percent reduction in atomic power generation. This disruption comes amid rising temperatures that have pushed river and coastal waters beyond ecological thresholds, forcing operators to limit reactor output to prevent harm to aquatic ecosystems. The issue centers around the need for nuclear plants to release vast amounts of waste heat, approximately two-thirds of the energy generated, into surrounding environments, typically rivers or seas. During periods of extreme heat, water temperatures rise rapidly, making it harder for plants to dissipate excess heat effectively. In response, many reactors are throttled back or shut down entirely to avoid exceeding legally mandated temperature limits designed to protect fish and other aquatic life. This process, while not an immediate threat to reactor safety, significantly reduces the availability of nuclear-generated electricity at critical times. France’s reliance on nuclear power is unparalleled in Europe, accounting for roughly 70 percent of the nation’s electricity production. With 13 reactors offline, concerns have arisen about potential disruptions to both domestic and regional energy markets. However, according to Électricité de France (EdF), the country’s primary utility operator, current electricity reserves remain adequate to meet seasonal demand. Additionally, increased solar power production and relatively low electricity consumption during the summer months have helped mitigate the impact of reduced nuclear output. Despite this, the loss of nearly 20 percent of nuclear capacity has raised questions about the resilience of France’s energy system under sustained heat stress. Similar challenges have emerged elsewhere in Europe. In Hungary, the Paks nuclear power plant, one of the largest in Central Europe, has faced operational difficulties due to critically low water levels in the Danube River. Normally responsible for generating about 40 percent of Hungary’s electricity, the facility has had to scale back operations, with only one of its four reactor units remaining active. While the plant has avoided a complete shutdown, the reduced output highlights the broader vulnerability of nuclear facilities to environmental conditions. The problems extend beyond river-based cooling systems. Coastal reactors, such as those at Gravelines in northern France, face different but equally pressing issues. Here, unusually high jellyfish populations have clogged intake filters, threatening the functionality of cooling systems. These biological obstructions, combined with elevated seawater temperatures, have led to the partial shutdown of several reactors. Gravelines, home to six reactors, is the largest nuclear facility in Western Europe, and its reduced capacity further strains the region’s energy landscape. Environmental groups have drawn attention to the ecological toll of nuclear operations. Anti-nuclear organizations cite internal documents suggesting that millions of marine organisms, including fish, jellyfish, crabs, and lobsters, perish annually within the cooling systems of French reactors. Critics argue that expanding nuclear capacity, such as the planned addition of four new reactors in Penly, Normandy, could exacerbate these impacts. EdF maintains that its operations do not negatively affect biodiversity, though the debate continues over the long-term sustainability of nuclear power in ecologically sensitive areas. As the heatwave persists, the focus shifts to managing short-term energy demands. Air conditioning usage has surged across Europe, increasing electricity consumption at a time when nuclear output is constrained. Grid operators are monitoring the situation closely, ensuring that alternative energy sources, such as renewables and imported electricity, are deployed effectively. While France has thus far maintained its status as an electricity exporter, the combination of heat-induced shutdowns and ecological protections underscores the delicate balance required to sustain reliable power generation in an era of climate extremes.

Robert Koch Institute: Number of heat deaths higher than expected

The Robert Koch Institute (RKI) has revised its estimates regarding heat-related deaths in Germany during the extreme heatwave at the end of June 2026. Initially, the institute had estimated more than 5,000 heat-related fatalities, but now reports 9,600 deaths between June 22 and 28 alone. This brings the total estimated number of heat-related deaths up to July 26 to 11,900, surpassing annual totals since 2016. The unusually high temperatures, which reached around 40 degrees Celsius in many parts of the country, were previously unprecedented in Germany. The RKI notes that these effects became apparent later due to the rarity of such temperatures and delays in reporting data from federal states. Most victims were elderly individuals over 84 years old, with pre-existing conditions contributing significantly to mortality.

Overheated reactors: French nuclear plants need cooling

France is experiencing difficulties with nuclear power production due to extreme heat and jellyfish infestations affecting cooling systems. Many reactors have been shut down because the water temperature of nearby rivers exceeds 28°C, which threatens aquatic ecosystems. At the Gravelines plant, jellyfish clogging filters pose additional challenges. With 13 out of 57 reactors offline, France faces a 20.4% reduction in nuclear electricity generation. However, energy supply remains stable due to lower seasonal demand and increased solar power production. The anti-nuclear group 'Sortir du Nucléaire' highlights environmental concerns, citing internal EDF documents that estimate over six billion marine organisms dying annually in cooling systems. EDF maintains that nuclear operations do not harm biodiversity.

When extreme heat threatens Europe's nuclear power

Extreme heat and low water levels in the Danube River have impacted nuclear power operations in Hungary, where the Paks nuclear plant has reduced its output due to insufficient water for cooling. Similarly, France, which relies heavily on nuclear energy, experienced temporary reductions in power generation during recent heatwaves, though overall electricity supply remained stable. While annual losses from heat-related disruptions are relatively small, short-term fluctuations during peak heat periods can significantly affect power availability. These issues highlight the vulnerability of nuclear power to environmental conditions and raise concerns about electricity supply stability during prolonged heatwaves.
