Extreme heat and low river water levels are causing nuclear power plants in Europe, especially in France and Hungary, to reduce output temporarily, threatening grid stability during peak demand periods. These temperature-related constraints could quadruple by 2050, challenging power supply resilience and increasing electricity prices in affected regions.
