#French #NuclearPower production expected to be reduced on Wednesday

By Reuters
August 12, 2025

PARIS, Aug 12 (Reuters) - "Power production at France's #Bugey3 #nuclear reactor in the east of the country is expected to be reduced by 500 megawatts (MW) on Wednesday, data from operator #EDF showed on Tuesday, as high river temperatures reduce the plant's ability to intake cooling water.

"A #heatwave throughout #France has led to multiple warnings of power reductions at a number of #NuclearPlants, particularly on the #RhoneRiver in the east and the #GaronneRiver in the west.

"The #Bugey 3 reactor has a maximum capacity of 910 MW, which will be reduced to 410 MW from 2:30 p.m. (1230 GMT) to midnight on Wednesday as the reactor is required to meet environmental safety measures, EDF's data showed.

"The high water temperature warnings for the #SaintAlban plant - down river of the Bugey site - and the #Golfech site in the west were moved to August 14, but restrictions have not yet been issued.
Average temperatures in the country are expected to continue to peak throughout the week, reaching a high of 28.5 degrees Celsius (83.3°F) on Saturday, LSEG data showed.

"#NuclearPower accounts for about 70% of total French power consumption annually, but August is the main holiday season throughout the country and electricity demand is often limited."

#Jellyfish Shut Four French #NuclearReactors as #HeatWave Builds

By Eamon Farhat
August 11, 2025

"#Electricite de France 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."

The #HeatWave of late June threatens French #nuclear production

Written by Justine Dumont, Energy Renovation Expert Editor on 24 June 2025 at 08:00

"#EDF plans to reduce the production of its nuclear fleet, in particular that of the #Bugey power plant in Ain, as of Wednesday 25 June, due to the expected high temperatures. This decision comes at a time when Météo-France has placed 16 departments in orange-heat-wave vigilance since Friday 20 June."

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."

NUKE WASTE DUMP: #Ojibwe Country once again targeted

May 1, 2025

"#BeyondNuclear’s radioactive waste specialist, Kevin Kamps, presented '#WaterIsLife, #NuclearWasteIsToxic' at the annual meeting of #EnvironmentNorth, in #ThunderBay, #Ontario, Canada, on the north shore of #LakeSuperior, April 23, 2025.

"Environment North is the lead local grassroots organization resisting the Canadian federal #NuclearWaste Management Organization’s (#NWMO, dominated by the nuclear industry, such as #OntarioPowerGeneration - #OPG) designation of the #IgnaceWabigoonLake #OjibwayFirstNation area as the national #RadioactiveWaste dump.

"A number of Ojibway #FirstNation Bands have also passed resolutions opposing the scheme, which would require long-distance, high-risk transportation of highly radioactive waste, from some two-dozen reactors to the east in #Canada, on the Great Lakes, Saint Lawrence, and Atlantic."

[Paywall] From 2021: Increase in frequency of nuclear power outages due to changing climate

by Ali Ahmad

Nature Energy volume 6, pages 755–762 (2021)

Abstract:

"Climate-related changes have already affected operating conditions for different types of energy system, in particular power plants. With more than three decades of data on changing climate, we are now in a position to empirically assess the impact of #ClimateChange on power plant operations. Such empirical assessments can provide an additional measure of the resilience of power plants going forward. Here I analyse climate-linked outages in #NuclearPowerPlants over the past three decades. My assessment shows that the average frequency of climate-induced disruptions has dramatically increased from 0.2 outage per reactor-year in the 1990s to 1.5 in the past decade. Based on the projections for adopted climate scenarios, the average annual energy loss of the global nuclear fleet is estimated to range between 0.8% and 1.4% in the mid-term (2046–2065) and 1.4% and 2.4% in the long term (2081–2100)."

We’re having a #heatwave...

And #NuclearPower can’t cope. Worse still, it’s actually a liability under ever more extreme climate conditions, write Karl Grossman and Harvey Wasserman

Posted on July 27, 2025, by #BeyondNuclear

"At the core of the latest attempted 'renaissance' of nuclear power is the big lie that #AtomicReactors are an answer to #GlobalWarming. In fact, they are significant sources of heat.

"There are more than 400 nuclear power plants in the world today that fission atoms at 300 degrees Centigrade, (572 degrees Fahrenheit). More are under construction or proposed. As the International Atomic Energy Agency states, 'water-cooled reactors offer heat up to 300 degrees Celsius. These types of reactors include pressurized water reactors (PWRs), boiling-water reactors (BWRs), pressurized heavy-water reactors, and light-water-cooled graphite-moderated reactors (LWGRs).'

"Some heat is absorbed in the water—drawn from water bodies—used to cool these nuclear power plants and then returned, still with considerable heat, to #rivers or #seas.

"The heatwave going on in recent weeks in Europe, in combination with this discharge of heated water from nuclear plants, has caused #NuclearPlants there to shut down.

"Consider these headlines from recent days:

" '#France and #Switzerland shut down nuclear power plants amid scorching heatwave,' was the July 3rd headline on Euronews. As the piece explained: “To cool down, nuclear power plants pump water from local rivers or the sea, which they then release back into water bodies at a high temperature. However, Europe’s ongoing heatwave means that the water pumped by nuclear sites is already very hot, impacting the ability of nuclear plants to use it to cool down. On top of this, nuclear sites run the risk of posing a dangerous threat to local #biodiversity, by releasing water which is too hot into rivers and seas.'

"A New York Times article, also dated July 3rd, related how in Europe, 'operators shut down one of the two reactors at the #Golfech nuclear power plant in southern #France after forecasts that the #GaronneRiver, from which it draws water and then discharges it after it is used in the plant as coolant, 'could top…82 degrees Fahrenheit.' The Times continued: 'The #Beznau Nuclear Power Plant in #Switzerland, built along the #AareRiver followed suit, shutting down one of its reactors on Tuesday and the other on Wednesday.' "

#FukushimaNuclearPlant clean-up faces yet another delay

Story by Mari Yamaguchi, July 29, 2025

"The full-scale removal of melted nuclear fuel from the #tsunami-wrecked #FukushimaDaiichi power plant has been delayed by several years, with the operator now targeting 2037 or later for the crucial operation.

"Tokyo Electric Power Company Holdings (#TEPCO) announced the setback on Tuesday, underscoring the immense challenges still facing the site.

"TEPCO stated that 12 to 15 years of preparation are required before commencing full-scale debris removal at the No. 3 reactor, involving radiation reduction and facility construction.

"An estimated 880 tons of melted nuclear fuel and structural debris remain within the three reactors that suffered meltdowns following the 2011 earthquake and tsunami.

"This latest delay further jeopardises the Japanese government and TEPCO's existing 2051 target for decommissioning the plant.

"A test retrieval of a small fuel sample in November was already three years behind schedule, with some experts suggesting the entire #decommissioning process could extend beyond a century.

"TEPCO said it plans to stick to the current completion target of 2051.

" 'Realistically, we are aware of the difficulty (to achieve the target) but we will not drop the goal just yet, as we still don't have a clear work schedule after the full-scale removal begins,' said Akira Ono, chief decommissioning officer at TEPCO.

"Ono said TEPCO plans to examine preparation work necessary at the two other reactors within the next couple of years ahead of full-scale melted fuel retrieval.

"After small missions by robots [that were fried by radiation] to gather samples, experts will determine a larger-scale method for removing melted fuel, first at the No. 3 reactor.

"In May, Japan announced plans to use slightly radioactive soil, stored near Fukushima nuclear plant, for flower beds outside Prime Minister #ShigeruIshiba’s office. [Maybe put more waste there as well! Useless politicians! Who have access to #PrussianBlue pills which remove #Cesium137 from one's body!]

"The move is intended to demonstrate the safety of reusing soil that was removed from Fukushima prefecture during decontamination efforts following the 2011 nuclear disaster. Officials say that some of the soil has now reached levels deemed safe for reuse." [Using faulty dosimeters, I'll wager!]

Listening to Indigenous views

“We believe that the Earth is our Mother, and that she has been violated, she has been hurt, she has been raped, she has been damaged for far, far too long,” - Chief Ron Tremblay, Wolastoq Grand Council.

Posted on December 1, 2024 by #BeyondNuclearInternational

"The study found that overall, Indigenous nations and communities do not support the production of more nuclear waste or the transport and storage of nuclear waste on their homelands. They have made their opposition known through dozens of public statements and more than 100 submissions to the regulator, the Canadian Nuclear Safety Commission.

"At the same time, the federal government positions nuclear energy as a strategic asset to Canada now and into the future. The government recently launched a policy to get nuclear projects approved more quickly, with fewer regulations. The government’s position has created an obvious conflict with Indigenous rights-holders.

#Radioactivity cannot be turned off – that’s what makes #NuclearWaste so dangerous. Indigenous opposition to nuclear waste is rooted in values that respect the Earth and the need to keep life safe for generations into the future. The radioactivity from high-level waste can take millennia to decay and if exposed, can damage living tissue in a range of ways and alter gene structure."

[PDF] National Association of Marine Laboratories
Position Paper

Scientific opposition to Japan’s planned release of over 1.3 million tons of radioactively contaminated water from the #FukushimaDaiIchi #NuclearPowerPlant
disaster into the #PacificOcean.

December 2022

“The National Association of Marine Laboratories (#NAML), an organization of more than
100 member laboratories, opposes Japan’s plans to begin releasing over 1.3 million tons of radioactively contaminated water from the Fukushima-Daiichi Nuclear Power Plant into the Pacific Ocean commencing in 2023. This opposition is based on the fact that there is a lack of adequate and accurate scientific data supporting Japan’s assertion of safety.

"Furthermore, there is an abundance of data demonstrating serious concerns about releasing radioactively contaminated water.

“The Pacific Ocean is the largest continuous body of water on our planet, containing the greatest biomass of organisms of ecological, economic, and cultural value, including 70 percent of the world’s #fisheries. The health of all the world’s #OceanEcosystems is in documented decline due
to a variety of stressors, including climate change, over-exploitation of resources, and pollution.

"The proposed release of this #contaminated water is a #transboundary and #transgenerational issue of concern for the health of marine ecosystems and those whose lives and livelihoods depend on them. We are concerned about the absence of critical data on the radionuclide content of each tank, the Advanced Liquid Processing System, which is used to remove radionuclides, and the assumption that upon the release of the contaminated wastewater,
‘dilution is the solution to pollution.’

“The underlying rationale of #dilution ignores the reality of biological processes of #OrganicBinding,
#bioaccumulation, and #bioconcentration, as well as accumulation in local seafloor sediments. Many of the radionuclides contained in the accumulated waste cooling water have half-lives ranging from decades to centuries, and their deleterious effects range from #DNADamage and
#cellular stress to elevated #cancer risks in people who eat affected marine organisms, such as clams, oysters, crabs, lobster, shrimp, and fish.

"Additionally, the effectiveness of the Advanced Liquid Processing System in almost completely removing the over 60 different #radionuclides present in the affected wastewater—some of which have an affinity to target specific tissues, glands, organs, and metabolic pathways in #LivingOrganisms, including people—remains a
serious concern due to the absence of critical data.

"The supporting data provided by the Tokyo Electric Power Company and the #JapaneseGovernment are insufficient and, in some cases, incorrect, with flaws in sampling protocols, statistical design, sample analyses, and assumptions, which in turn lead to flaws in the
conclusion of safety and prevent a more thorough evaluation of better alternative approaches to disposal. A full range of approaches to addressing the problem of safely containing, storing, and disposing of the radioactive waste have not been adequately explored, and alternatives to ocean dumping should be examined in greater detail and with extensive scientific rigor.

“NAML calls on the Government of #Japan and International Atomic Energy Agency (#IAEA) scientists to more fully and adequately consider the options recommended by the #PacificIslandsForum’s Expert Panel. We believe public policy decisions, regulations, and actions must keep pace with and make use of relevant advancements in our scientific understanding of the #environment and human health. In this case, we believe policy makers have not fully availed themselves of the available science and should do so before making any final decisions on releasing this contaminated water into the Pacific. NAML members are unified in our concern about use of the oceans as a dumping ground for radioactively contaminated water and other #pollutants because such actions can negatively affect the long-term health and sustainability of
our planet.

“We urge the Government of Japan to stop pursuing their planned and precedent-setting release of the radioactively contaminated water into the Pacific Ocean and to work with the broader scientific community to pursue other approaches [like #ClosedLoop systems or binding radionuclides in concerete] that protect #OceanLife; human health; and
those communities who depend on ecologically, economically, and culturally valuable marine
resources. “

Explainer | Why do many scientists oppose #Fukushima #radioactive waste discharge?

The release of treated waste water from the #NuclearPlant has begun, despite concerns from major scientific organisations

IAEA is monitoring the operation but many experts are questioning the amount of data being collected

by Victoria Bela
Published: 2:05pm, 30 Aug 2023

"Japan’s decision to start releasing around 30 years’ worth of treated radioactive waste into the #PacificOcean on #August24 has drawn criticism from some countries, including China, as well as some of the world’s leading scientific organisations.

"The plan to deal with the 1.3 million tonnes of contaminated water accumulated since the #FukushimaDaiichi #NuclearPowerPlant meltdown in 2011 includes removing most of the radioactive chemicals before it is discharged into the ocean.

[...]

"However, the ALPS has been shown to be unsuccessful in filtering out the other 62 radioactive chemicals present in the waste water, according to data from the Japanese ministry for economy, trade and industry (#METI).

"According to METI, around 70 per cent of ALPS-treated water still contained #radioactive substances other than #tritium by the end of 2020, and needed to be #repurified.

"The US-based National Association of Marine Laboratories (#NAML), which represents more than 100 labs, released a position paper in December 2022 [link in comments] that firmly opposed Japan’s plan over 'a lack of adequate and accurate scientific data' about its safety.

"NAML members include some of the world’s most influential marine research institutes, including the #ScrippsInstitution of #Oceanography at the University of California, San Diego."

Meta-analysis of the thermal pollution caused by coastal nuclear power plants and its effects on marine #biodiversity

Louiza Soares Ferreira Guimaraes, et al.

October, 2023

Abstract:

"The rise in seawater temperature due to industrial activities is one of the main threats to marine biodiversity. In nuclear power plants, large volumes of water are used for their operation, returning to the #ecosystem at higher temperatures. A global meta-analysis was performed to evaluate the thermal effects caused by coastal #NuclearPowerPlants on marine organisms. We found 853 articles of which, 99 were included in the qualitative analysis and 75 in the meta-analysis. The meta-analysis showed an increase of 4.38 °C in water temperature near the outfall, and the temperature variation of each study was found to be associated with the power plant latitudes. The main effects on organisms were related to changes in the structure and composition of aquatic communities, with species abundance, distribution, dominance, and density being the most cited ones. Among the affected groups, photosynthesizing microorganisms were the most cited, potentially contributing to shifts in ecosystem dynamics."

Highlights

• Thermal discharges of nuclear plants caused an increase of 4.38 °C in nearby seawater.
• The temperature difference between sites was correlated with power plant latitudes.
• 38 studies linked temperature as the main factor affecting marine organisms.
• Shifts were noted especially in species abundance (14.65 %) and distribution (13.79 %).
• Among the affected organisms, photosynthesizing microorganisms were the most cited.
