#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."

#Jellyfish attack #NuclearPowerPlant. Again.
By Susan D’Agostino | October 28, 2021
" #Scotland’s only working nuclear power plant at #Torness shut down in an emergency procedure when jellyfish clogged the sea water-cooling intake pipes at the plant, according to the Scotland Herald this week. Without access to cool water, a nuclear power plant risks overheating. The intake pipes can also be damaged, which disrupts power generation. And ocean life that gets sucked into a power plant’s intake pipes risks death.
[...]
"The clash between gelatinous jellyfish and hulking nuclear power plants has a long history. These spineless, brainless, bloodless creatures shut down the Torness nuclear power plant in 2011 at a cost of approximately $1.5 million per day, according to one estimate. Swarms of these invertebrates have also been responsible for nuclear power plant shutdowns in Israel, Japan, the United States, the #Philippines, #SouthKorea, and Sweden.
"Humans have unwittingly nurtured the adversarial relationship between jellyfish and nuclear power plants. That is, human-induced #ClimateChange has raised ocean water temperatures, setting conditions for larger-than-usual jellyfish populations. Further, the relatively warm water near nuclear power plant discharge outlets may attract jellyfish swarms, according to one study. Also, #pollution has lowered #oxygen levels in sea water, which jellyfish tolerate more than other marine animals, leading to their proliferation.
"Some look at jellyfish and see elegant ballerinas of the sea, while others view them as pests. Either way, they are nothing if not resilient. Jellyfish are 95 percent water, drift in topical waters and the Arctic Ocean, and thrive in the ocean’s bottom as well as on its surface. Nuclear power plant operators might take note: Older-than-dinosaur jellyfish are likely here to stay."

#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!]

Het slechte imago van kwallen is vaak helemaal onterecht, zoals bij deze prachtige oorkwal, aangespoeld op het strand. Aan de kleur van haar geslachtsorganen kun je zien dat het een vrouw is. Haar tentakels zijn voor mensen onschadelijk. Kwallen bestaan voor ongeveer 95% uit water en onder de hoed hebben ze een spijsverteringsorgaan dat kleine visjes en garnaaltjes kan verteren.

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
