LILLE, FRANCE<\/strong>\u00a0\u2013 A massive swarm of jellyfish forced the complete shutdown of Western Europe’s largest nuclear power station on Monday, highlighting the unexpected ways climate change is affecting critical infrastructure.<\/p>\n\n\n\n

The Gravelines nuclear facility in northern France was brought to a standstill after jellyfish clogged the pumps used to cool its reactors, energy giant EDF announced yesterday.<\/p>\n\n\n\n

Four of the plant’s six reactors automatically shut down when the marine creatures blocked filter drums at the pumping stations, whilst the remaining two units were already offline for scheduled maintenance.<\/p>\n\n\n\n

“These shutdowns are the result of the massive and unpredictable presence of jellyfish in the filter drums of the pumping stations,” EDF said in a statement on its website.<\/p>\n\n\n\n

The company was quick to reassure the public that the automatic safety measures “had no impact on the safety of the facilities, the safety of personnel, or the environment.”<\/p>\n\n\n\n

Swift response expected<\/h2>\n\n\n\n

Engineering teams were conducting thorough inspections on Monday evening, with EDF expressing confidence that production could resume safely by Thursday.<\/p>\n\n\n\n

“There is no risk of a power shortage,” the energy provider emphasised, noting that alternative sources including solar power remained fully operational to meet demand.<\/p>\n\n\n\n

The Gravelines site, located on France’s northern coast, houses six reactors capable of generating 900 megawatts each. The facility is also earmarked for expansion, with two next-generation reactors scheduled for completion by 2040, each boasting a capacity of 1 600 megawatts.<\/p>\n\n\n\n

Rare but recurring problem<\/h2>\n\n\n\n

Whilst jellyfish-induced shutdowns remain uncommon, this is not an unprecedented occurrence. EDF described such incidents as “quite rare,” noting that the last similar disruption to their operations occurred in the 1990s.<\/p>\n\n\n\n

However, nuclear facilities worldwide have occasionally fallen victim to jellyfish invasions. Sweden experienced a three-day closure in 2013, whilst Japan faced a significant output reduction in 1999 due to similar circumstances.<\/p>\n\n\n\n

Marine biologists attribute the increasing frequency of jellyfish blooms to a combination of overfishing, plastic pollution, and climate change, which have created ideal conditions for these creatures to thrive and reproduce rapidly.<\/p>\n","protected":false},"excerpt":{"rendered":"
