#Kansas town is getting an underground #nuclear reactor [whether they like it or not!]
Story by Jessie Williams, July 29, 2026
"A pilot project to bury a #NuclearReactor one mile underneath a town in Kansas has split the opinion of local residents, with some fearing the #EnvironmentalImpacts while others hope it will create economic opportunities.
"The so-called #GravityReactor is being proposed by #DeepFission, a California-based start-up from a father-daughter duo, #LizMuller and #RichardMuller, emeritus professor of physics at University of California, and an inventor.
"It will be the first time a commercial nuclear reactor operates underground.
"The startup has raised around $150 million in the past year, with $40 million of that going to fund the work in #ParsonsKS, a rural town in Kansas with a population of 9,600.
"So far Deep Fission has drilled one test hole with a second due to be completed this year, and a full-scale prototype canister intended to test installation procedures.
"Their plan is to send the canister loaded with nuclear fuel into a third hole to heat water a mile underground and generate electricity on the surface in 2027 or 2028.
"But some people in Parsons are worried about the short time frame by industry standards and the impact on the #environment and their #WaterSupply.
"Each reactor would generate 15 megawatts of electricity from inside a 30-inch borehole, enough to power 12,000 homes. But Muller wants 100 or more reactors, providing more than a gigawatt – which would be enough for a #datacentre.
"The design relies on established pressurised water reactor technology, but with the reactor one mile underground, Deep Fission says it could remove some of the most expensive parts of conventional #NuclearPlants, as rock and water pressure could replace some costly #safety structures, such as #cooling and #containment.
"Nuclear only generates about a fifth of US electricity, but the Trump administration is seeking to kickstart a '#NuclearRenaissance,' aiming to quadruple America’s nuclear-power generation by 2050. It comes amid skyrocketing demand for electricity, mainly driven by data centres for AI."

Europe's #heatwave curbs French #NuclearPlants
By Forrest Crellin and Hugo Lhomedet
June 24, 2026"The heat has reduced output at the #SaintAlban2 and #Bugey 3 reactors on the Rhone river in eastern France, and the #Nogent2 reactor on the Seine southeast of Paris.
"The #Golfech2 reactor on the Garonne river in southwest France went offline late Monday due to the heat.
"French environmental regulations force nuclear operator #EDF to reduce output when river temperatures reach a certain threshold to protect local ecosystems.
"It was not certain how long the current heatwave, driven by a weather pattern known as an #OmegaBlock due to its shape, which allows temperatures to build day after day, would last.
"Europe is warming at more than twice the global average, the World Meteorological Organisation has said, which makes prolonged heat episodes increasingly likely."

#SouthernCalifornia #wildfires force evacuations, and one is threatening a #nuclear facility
Evacuations remain in place for fires burning in #Ventura and #Riverside counties. The Sandy Fire in #SimiValley is burning near the #SantaSusanaFieldLaboratory, a former #NuclearReactor site, raising #AirQuality concerns.
By Emilee Speck, AccuWeather staff writer
Published May 21, 2026 1:08 PM EDT | Updated May 22, 2026 12:04 PM EDT
Excerpt: "Due to the Sandy Fire’s proximity to the Santa Susana Field Laboratory, a former nuclear reactor and rocket testing facility, officials are conducting air quality monitoring around the fire perimeter.
" 'Monitoring equipment has been proactively deployed to establish background air quality readings and to help assess conditions should the fire advance further into the area,' according to CAL Fire. 'At this time, the fire has not crossed into the Field Laboratory property.'
"Nuclear cleanup continues more than 50 years after a nuclear reactor mishap at the #Rocketdyne site. Fire crews are prioritizing the protection of the facility and the surrounding communities. "

The #Trump Administration exempts new #nuclear reactors from #environmental review
Geoff Brumfiel, February 2, 20263:09 PM ET
"The Trump Administration has created an exclusion for new experimental reactors being built at sites around the U.S. from a major environmental law. The law would have required them to disclose how their construction and operation might harm the environment, and it also typically required a written, public assessment of the possible consequences of a #NuclearAccident.
"The exclusion announcement comes just days after NPR revealed officials at the Department of Energy had secretly rewritten environmental, safety and security rules to make it easier for the reactors to be built.
"The Department of Energy announced the change Monday in a notice in the Federal Register. It said the department would begin excluding advanced nuclear reactors from the #NationalEnvironmentalPolicyAct. The act requires federal agencies to consider the environment when undertaking new projects and programs.
"The law also requires extensive reporting on how proposed programs might impact local ecosystems. That documentation, known as an #EnvironmentalImpactStatement, and a second lesser type of analysis, known as an #EnvironmentalAssessment, provide an opportunity for the public to review and comment on potential projects in their community."

#French #NuclearPower production expected to be reduced on Wednesday
By Reuters
August 12, 2025PARIS, 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."

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."

Nuclear watchdog ASN mentions that limits were raised, but the article does not mention those limits. I'll be keeping a watchful EYE 👁️ on this story (and see what I can dig up...!) (From 2023: France’s #NuclearPower stations to limit energy output due to high river temperatures
By Euronews Green with Reuters
Published on 13/07/2023"EDF is committed to adapting its facilities to #ClimateChange, a company spokesperson said. They added that since 2000, losses due to high river temperatures have represented an average drop of just 0.3 per cent of annual power production.
"The nuclear operator said previously a study it conducted showed last year's higher temperatures had no impact on biodiversity.
"However, a study conducted by French #nuclear watchdog #ASN saw a slight increase in #algae and #plankton growth around the #BugeyPlant during the #HeatWave. Fish populations were also affected through the autumn at the #SaintAlban plant.
"The watchdog stipulated it is currently impossible to distinguish the impact of the raised limits compared to the other #ecological effects of the #HeatWave, but it is continuing to monitor the river #biome."

From 2011:
In Tennessee, #HeatWaves Diminish #Nuclear Power Output
By Alyson Kenward
April 10, 2011"On July 8, 2010, as the temperature in downtown Decatur, Alabama climbed to a sweltering 98°F, operators at the #BrownsFerry #NuclearPowerPlant a few miles outside of town realized they had only one option to avoid violating their #environmental permit: turn down the reactors. For days, the Tennessee Valley Authority (#TVA), which owns the nuclear plant, had kept a watchful eye on the rising mercury, knowing that more heat outside could spell trouble inside the facility. When the #TennesseeRiver, whose adjacent waters are used to cool the reactors, finally hit 90°F and forced Browns Ferry to run at only half of their regular power output, the TVA hoped the hot spell would last just a few days.
"Eight weeks of unrelenting heat later, the plant was still running at half its capacity, robbing the grid of power it desperately needed when electricity demand from #AirConditioners and fans was at its peak. The total cost of the lost power over that time? More than $50 million dollars, all of which was paid for by TVA’s customers in Tennessee.
"The Browns Ferry nuclear plant, located on the Wheeler Reservoir along the Tennessee River near Athens, Alabama. It has three reactors, each producing about 1000 megawatts of electricity. Credit: Nuclear Regulatory Commission.
“'Last summer, the water in the Tennessee River warmed up early and stayed warm,' says TVA spokesman Ray Golden. 'When it got hot again in July and August, we were impacted by that and had to reduce power at the plant and get it from somewhere else.'
"With river water so warm, the #NuclearPlant couldn’t draw in as much water as usual to cool the facility's three reactors, or else the water it pumped back into the river could be hot enough to harm the local #ecosystem, says Golden. But for every day that the Browns Ferry plant ran at 50 percent of its maximum output, the TVA had to spent $1 million more than usual to purchase power from somewhere else, he says.
"What happened in northern Alabama last summer, at the largest of TVA's nuclear power plants, did not present a human safety concern. Operators knew there was never a risk of an explosion or nuclear meltdown, nor was there a threat of leaking radioactive material. But the prolonged spell of hot weather put the TVA at risk of violating environmental permits, with hefty fines as one consequence and potential harm to the Tennessee River ecosystem as another.
"It’s not the first time high temperatures have affected the performance of the Browns Ferry plant, and extreme heat is a growing concern for power plant operators across the #Southeast. While some nuclear plants can improve their cooling procedures to cope with the intake of warmer water, the upgrades can cost hundreds of millions of dollars and still don’t offer an indefinite defense against extreme heat. Because scientists say the Southeast (like many other parts of the world) can expect to see more frequent and intense heat waves by the end of this century, the problems for nuclear power and the people that rely on it for electricity may only be beginning.
#ExtremeHeat Limits Nuclear Energy Production
"The disaster still unfolding at Japan’s #FukushimaDaiichi nuclear plant has refocused America's attention on nuclear power, calling into question its future role in the country's energy portfolio. Many advocates of nuclear power say that we need to maintain — and even expand — nuclear power to get away from using fossil fuels, such as coal, and to help lower greenhouse gas emissions.
"But nuclear power has a paradoxical relationship with #ClimateChange. Even though it might help mitigate long-term #GlobalWarming, nuclear power is already being challenged by rising temperatures and the increasing number of heat waves around the world. Throughout the last decade, several plants have had to reduce electricity production during heat waves, just when when electricity demand typically reaches peak levels.
“'It’s a dilemma between mitigation of climate change, and adaptation to it,' says Natalie Kopytko, an energy policy doctoral student at the University of York in England. Having recently studied the ways in which climate change could have a negative impact on nuclear power, she says nuclear power is caught in the middle because it could be used to help lower greenhouse gas emissions, but global warming is making the technology less effective at providing electricity."

Nuclear Power Plants: #NRC Should Take Actions to Fully Consider the Potential Effects of #ClimateChange
GAO-24-106326 Published: Apr 02, 2024.
"Climate change is likely to exacerbate natural hazards—such as #floods and #drought. The risks to nuclear power plants from such hazards include damage to systems and equipment that ensure safe operation.
"The Nuclear Regulatory Commission's oversight process includes addressing safety risks at these plants. However, NRC doesn't fully consider potential increases in risk from climate change. For example, NRC mostly uses historical data to identify and assess safety risks, rather than data from future climate projections.
"We recommended that NRC fully address climate risks to nuclear power plants.
"Climate change is expected to exacerbate natural hazards—including heat, drought, #wildfires, #flooding, #hurricanes, and #SeaLevelRise. In addition, climate change may affect #ExtremeCold weather events. Risks to nuclear power plants from these hazards include loss of offsite power, damage to systems and equipment, and diminished cooling capacity, potentially resulting in reduced operations or plant shutdowns.
"The Nuclear Regulatory Commission (NRC) addresses risks to the safety of nuclear power plants, including risks from natural hazards, in its licensing and oversight processes. Following the tsunami that led to the 2011 accident at Japan's #FukushimaDaiichi nuclear power plant, NRC took additional actions to address risks from natural hazards. These include requiring safety margins in reactor designs, measures to prevent radioactive releases should a natural hazard event exceed what a plant was designed to withstand, and maintenance of backup equipment related to safety functions.
"However, NRC's actions to address risks from natural hazards do not fully consider potential climate change effects. For example, NRC primarily uses historical data in its licensing and oversight processes rather than climate projections data. NRC officials GAO interviewed said they believe their current processes provide an adequate margin of safety to address climate risks.
"However, NRC has not conducted an assessment to demonstrate that this is the case. Assessing its processes to determine whether they adequately address the potential for increased risks from climate change would help ensure NRC fully considers risks to existing and proposed plants. Specifically, identifying any gaps in its processes and developing a plan to address them, including by using climate projections data, would help ensure that NRC adopts a more comprehensive approach for assessing risks and is better able to fulfill its mission to protect public health and safety."

Nuclear Expansion Sparks Concerns from Scientists of '#CatastrophicFailure'
Story by Jordan King
June 19, 2024"A group of scientists has spoken out against a new bill that aims to accelerate the development of #nuclear energy.
"The U.S. Senate passed the #ADVANCEAct on Tuesday, which, among other things, makes it easier and quicker for companies to apply for permits and creates new incentives for advanced #nuclear reactor technologies.
"It was passed with bipartisan support (88-2 votes), with Democrats getting behind it for environmental reasons and Republicans seeing it as a way to ensure electricity supply and create jobs.
"An example of how the bill could be applied is with the Bill Gates-backed company #TerraPower, which has so far been unable to secure a permit to build a $4 billion #Natrium Reactor on an old #coal plant site in Wyoming, Reuters reports.
"But the Union of Concerned Scientists, a science advocacy nonprofit, is worried about the #safety implications of the bill, which is now on its way to President Joe #Biden to sign into law.
"The organization's director of nuclear power safety Dr. #EdwinLyman compared the Nuclear Regulatory Commission's [#NRC] relaxing of rules to the Federal Aviation Administration doing the same with air transport."
