#Jellyfish Shut Four French #NuclearReactors as #HeatWave Builds
By Eamon Farhat
August 11, 2025" #ElectriciteDeFrance SA [#EDF] was forced to shut four #AtomicReactors after a swarm of jellyfish clogged up filter drums at its #Gravelines power plant.
"The 'massive and unforeseen' [um, not if you read my posts -- very much FORESEEN] presence of jellyfish in the filter drums of pumping stations closed four out of six reactors at Gravelines on the north coast of France, EDF said in a statement on Monday. Pumping stations for coastal #NuclearPlants usually draw in sea water for cooling, sometimes exposing them to marine life.
"A #MarineHeatWave is intensifying off the west coast of France, with unusually warm waters in the English Channel near Gravelines, data from #Copernicus Marine Service show. Jellyfish populations can 'bloom' at such times, and France has closed several beaches in recent weeks due to invasions of the eight-legged molluscs, according reports compiled by the beach information app Meduseo."

Invasion of #jellyfish, heat, water too hot: #GlobalWarming threatens the functioning of #NuclearPowerPlants
Several reactors are regularly forced to stop to protect river #biodiversity. While cuts in periods of high heat still have a very limited impact on supply, electrification of uses and #ClimateChange could make a difference.
Marie Toulgoat , Published 11 August 2025
"When nature paralyses the French nuclear park. Four units of the Gravelines nuclear power plant (northern) are at a standstill on Monday 11 August due to the 'mass and unforeseeable presence of jellyfish; at the water pumping stations used for the cooling of the reactors, EDF announced.
"These automatic stops of units 2, 3, 4 and 6 'have had no consequences on the safety of the installations, the safety of personnel or on the environment', #EDF assures on its site. The plant is thus temporarily completely shut down, as its other two production units 1 and 5 are currently under maintenance.
"On Sunday, 29 June, no steam volutes escaped from the chimneys of the Gulf nuclear power plant (Tarn-et-Garonne). Due to the intense #HeatWave in #France, the reactor in operation at the site was shut down. In the middle of the summer of 2024, the nuclear power plant had already been forced to reduce its production."

It’s not mentioned here, but I remember seeing a TV programme documenting credible Great White shark sightings in UK waters. Even as far North as Scotland. With some of the biggest seal populations in the world, and water temperatures well within their limit, some scientists wonder why Great Whites aren’t here!Record warm seas help to bring extraordinary new species to UK waters https://www.bbc.com/news/articles/c05enyryqvmo

#Jellyfish Keep Attacking #NuclearPowerPlants
By Gabriel Geiger
November 2, 2021"Jellyfish are continuing to clog the cooling intake pipes of a nuclear power plant in Scotland, which has previously prompted a temporary shutdowns of the plant.
"The #TornessNuclearPowerPlant has reported concerns regarding jellyfish as far back as 2011, when it was forced to shut down for nearly a week—at an estimated cost of $1.5 million a day—because of the free-swimming marine animals.
"In a short comment to Motherboard, #EDFEnergy, which runs the Torness plant, said that 'jellyfish blooms are an occasional issue for our power stations,' but also said that media reports claiming the plant had recently been taken offline because of jellyfish are 'inaccurate.' '[There were] no emergency procedures this or last week related to jellyfish or otherwise,' a spokesperson said. [Um, did they previously work for #TEPCOLies?]
" 'Like many other seaside power plants, the Torness plant uses seawater to prevent overheating. While there are measures in place to prevent aquatic life from entering the intake pipes, according to the #BulletinOfTheAtomicScientists, they are no match for the sheer number of jellyfish that come during so-called 'jellyfish blooms.'
" 'Usually, screens prevent aquatic life and similar debris from being drawn into the power plants’ cooling system,' the Bulletin of the Atomic Scientists wrote in a 2015 blog post. 'But when sufficiently large volumes of jellyfish or other aquatic life are pulled in, they block the screens, reducing the volume of water coming in and forcing the reactor to shut down.'
"While the case in Scotland has once again spotlighted concerns regarding the jellyfish and potential power plant shutdowns, these concerns are far from new. In 2008, a swarm of jellyfish shut down a nuclear power plant [#DiabloCanyon -- which had another incident in 2024] in #California, and three years later the same occurred at a plant in Japan [#Shimane]. In 2017, jellyfish clogged a power plant in Israel [#Hadera]."

#Jellyfish are taking over the world – and #ClimateChange could be to blame
Jan 8, 2019
by Sean Fleming
Senior Writer, Forum Stories"For 500 million years, jellyfish have been part of the maritime #ecosystem, but now they’re poised to take over the earth.
"They have no brain, no eyes, no spine, not even blood, but they have a remarkable capacity to reproduce and can pack an impressive sting, both literally and figuratively.
"Most recently, vast numbers of bluebottle jellyfish were pushed ashore by unusually strong winds and spells of hot weather in #QueenslandAustralia, stinging thousands of people and forcing the closure of popular swimming spots. About 13,000 stings were recorded in the past week.
"In June last year, over the course of just one week, over 1,000 people were stung in Volusia County, #Florida, following a period of exceptionally prolific jellyfish blooms. The explosion in their numbers has been attributed to warming seas and even increased pollution; unlike many other marine creatures, jellyfish can cope with reduced oxygen levels.
Small but deadly – at least some of the time
"Typically, jellyfish range in size from 1cm to 40cm. But they can be significantly larger – the #LionsManeJellyfish, for example, can reach 1.8 metres wide, with tentacles over 15 metres long.
"For the most part, the sting of a jellyfish is more unpleasant than it is harmful. The pain comes from venom delivered via millions of microscopic barbs in the creatures’ tentacles. Most jellyfish stings will only have a localized effect on the victim – redness, swelling, and discomfort where the barbs make contact with the skin.
"Some, however, will prompt a systemic, whole body, reaction. These may take several hours to emerge and can include symptoms such as headaches, nausea and drowsiness.
"In rare cases, the sting can be fatal. This is true of the #BoxJellyfish, which is spreading into waters that had previously been too cool to support it; its venom causes a severe reaction that can cause death within minutes.
A force of destruction
"But these booming jellyfish populations are doing far more harm than ruining people’s trips to the beach. In fact, the scope of their disruption has extended far beyond the water’s edge.
"In 2011, both reactors at the #TornessNuclearPowerPlant in #Scotland were shut down after an invasion of jellyfish started blocking the cooling filters. Two years later, the jellyfish struck again – this time in #Sweden. They forced the closure of the #OskarshamnNuclearPowerPlant, which contains the world’s largest boiling-water reactor.
"The island of Luzon, home of the Phillippines’ capital Manilla, suffered a blackout in 1999 due to jellyfish, and in 2006 the #USSRonaldReagan, a nuclear-powered aircraft carrier, was brought to a standstill by thousands of the little creatures. And while these events may stand out as exceptions, they are increasing in both scale and frequency.
"From sea-bed diamond mining in Namibia to salmon farming in Ireland, even jeopardising the sustainability of beluga caviar farming in the Caspian Sea, jellyfish are as destructive as they are abundant. And that abundance is being caused by a variety of factors, many of which are related to human activity.
Some like it hot
"Over the last hundred or so years, the average surface temperature of the world’s seas has risen by about 0.9°C. As the oceans get warmer, marine animals are able to spread into areas that had historically been too cold. Oxygen levels in the sea have fallen by around 2% over the last 50 years, due to rising temperatures and #pollution [including #NuclearOceanDumping, which reduces oxygen levels]
"Jellyfish can thrive in areas with lower oxygen levels, where other animals suffer. But there are other factors at work, too. Fishing has depleted the global stocks of some of the jellyfish’s natural predators – such as #tuna and #swordfish – and some they compete with for food – such as anchovies. With more food and fewer predators, some jellyfish populations can grow unchecked.
"In the #BlackSea, unchecked population growth is precisely what’s happened. #AnchovyFishing in the region had caused harm to the Black Sea’s ecosystem by the time stowaway jellyfish made the journey there from the eastern seaboard of the USA. Most likely transported in the ballast water of ships that made the crossing, 1982 saw the arrival of the warty comb jelly. By 1990, there were 900 million tons of them in the Black Sea.
"There are believed to be around 200 different species of jellyfish, not all of which can sting, and some are considered edible. This could offer one potential, and creative, approach toward dealing with an over-abundance of jellyfish – co-opting them onto our dinner plates." [That's one way to deal with invasive species -- eat them into extinction!]

El cangrejo, probablemente un Dorippe frascone, lleva a la medusa Cassiopea, que suele nadar invertidas. Usa sus dos pares de patas posteriores para agarrarla y sus dos pares anteriores para caminar. De esta manera, está protegido por la medusa. #cangrejo #crab #medusa #jellyfish
