EDF says a nuclear plant in northern France shuts down three reactors after a swarm of jellyfish clogs cooling pumps. EDF reports that three reactors are taken offline on Monday, while output at a fourth reactor is cut by half. A sixth reactor is already out of service for scheduled maintenance.

EDF also states the incident does not affect safety, personnel, or the environment. Both outlets describe the cause as a cooling-system disruption rather than damage to equipment or any radiation-related event. The Local provides a brief account that mirrors EDF’s statement, while South China Morning Post adds details on reactor status, including how many units are operating at full capacity versus reduced capacity. The reports do not describe any wider impact beyond the plant’s operating changes and the temporary shutdowns.
