一个月两次！法国核电站频遭水母“暗算“关停

Core Viewpoint - The recent jellyfish invasion at French nuclear power plants highlights the growing risks associated with climate change and its impact on energy production, particularly in the context of rising sea temperatures and increased jellyfish populations [5][6]. Group 1: Incident Overview - A jellyfish invasion caused the temporary shutdown of one reactor and a reduction in capacity of another at the Paluel nuclear power plant, affecting nearly 2000 megawatts of power generation [1]. - The jellyfish blocked the cooling system's water pumps, disrupting the cooling process of the generators [2]. - The Gravelines nuclear power plant also experienced a similar jellyfish issue in mid-August, leading to a ten-day shutdown of four reactors [2]. Group 2: Response and Mitigation - EDF learned from the previous incident and proactively shut down the power generation equipment upon detecting the jellyfish [2]. - The jellyfish only impacted the "non-nuclear" parts of the power station, and other plants in France increased their output to compensate for the lost generation [4]. Group 3: Broader Implications - The overpopulation of jellyfish is attributed to warming sea temperatures, with this summer being one of the hottest on record in Europe [5]. - France generates 68.6% of its electricity from nuclear energy, with 14 out of 57 reactors using seawater for cooling, indicating a potential increase in jellyfish-related incidents if global warming continues [6]. - EDF had previously planned to install "acoustic deterrent devices" at the Hinkley Point C nuclear power station, referred to as "fish disco," but this project has not been implemented yet [6].
