Nuclear power plant in France halted due to jellyfish invasion
Jellyfish Shutdown at France's Gravelines Nuclear Plant
A temporary shutdown of four units at the Gravelines nuclear plant in northern France occurred on Monday due to a massive swarm of jellyfish[1]. The plant, operated by EDF, is Western Europe's largest nuclear power facility, with a total capacity of 5,400 megawatts[2].
The site was fully shut down following the incident, as two other units were already offline for maintenance[3]. The shutdown was due to jellyfish clogging pumps used to cool the reactors[4]. Despite this, the energy group assured that the automatic shutdown had no impact on the safety of the facilities, personnel, or the environment[5].
Jellyfish shutdowns at nuclear power plants are relatively rare but have occurred in several instances globally[6]. Historical incidents in Sweden, Japan, and Scotland demonstrate a recurring pattern of marine life disruptions affecting coastal energy infrastructure[7].
Several factors contribute to the occurrence of jellyfish invasions that can impact nuclear power plants. Climate change, invasive species, global species transport, and environmental conditions are key contributors[8]. Warming oceans, disrupted marine ecosystems, the introduction of non-native species, and changes in ocean currents can facilitate the formation of jellyfish blooms[9].
Experts attribute the increase in jellyfish populations to factors like overfishing, plastic pollution, and climate change[10]. The Gravelines plant operator expects the affected units to restart on Thursday[5]. Two next-generation reactors, each with a capacity of 1,600 megawatts, are scheduled to open at Gravelines by 2040[2].
Inspections are being carried out to ensure the restart of the production units at Gravelines in complete safety. Meanwhile, other energy sources, including solar power, are operational to prevent a power shortage[11]. Despite the temporary shutdown, the Gravelines nuclear plant continues to play a crucial role in France's energy production.

- Climate change, one of the factors contributing to jellyfish invasions, may pose future challenges for the environmental-science and finance sectors, given its impact on marine ecosystems and energy production, as illustrated by the recent shutdown of France's Gravelines nuclear plant.
- The occurrence of jellyfish shutdowns in the industry, such as the one at France's Gravelines nuclear plant, highlights the need for investment in environmental-science research to better understand and mitigate the effects of climate change on coastal energy infrastructure.
- As alternative energy sources like solar power are operational during the Gravelines nuclear plant's temporary shutdown, there is an opportunity to examine the role of energy efficiency and the financial implications in offsetting potential power shortages caused by climate-change-related events.
