#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."

"In a detailed report released last week, titled The Urgent Case Against #DataCenters, #FWW pointed to some of the 'documented harms caused by #AI and data centers,' including:
- Enormous #energy footprints: A single hyperscale data center can consume as much energy as 2 million US households.
- A lifeline for #FossilFuels: The thirst for fuel is being met by keeping old #coal-fired power plants running and by building new natural gas ones. [And restarting old #NuclearPlants]
- Skyrocketing electricity costs: Increased #EnergyDemand can raise residential rates, which soared 31% from 2020 to 2025 (compared to 4% from 2015 to 2020).
- Drained water resources: By 2028, AI data centers could use as much water as 18.5 million households, just for cooling their servers.
- An investment bubble: A handful of companies are investing in one another and increasingly turning to risky debt structures to hide the threat of the bubble.
- A litany of other harms: This includes massive amounts of electronic waste (#EWaste), unrelenting noise pollution, loss of #farmland, political instability from #deepfake videos, lost revenue from data center tax incentives, and #ChildEndangerment from #AI #chatbots."#NoDatacenters #NoAI

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."

CA #wildfires: a warning to #NRC on #ClimateChange
January 16, 2025
"The NRC’s actions to address the risks from natural hazards do not fully consider potential climate change effects on severe nuclear accident risks. 'For example, NRC primarily uses historical data in its licensing and oversight processes rather than climate projections data,' the GAO report said.
"Beyond Nuclear has uncovered similar findings during our challenges to the NRC’s extreme relicensing process for extending reactor operating licenses, now out to the extreme of 60 to 80 years and talk of 100 years. We found that the agency’s staff believes and stubbornly insists that an #environmental review for climate change impacts (#SeaLevelRise, increasingly severe #hurricanes, extreme #flooding, etc.) on reactor safety and reliability is 'out of scope' for the license extensions hearing process.
"The GAO report points out to the NRC that wildfires, specifically, can dangerously impact US nuclear power stations operations and public safety with potential consequences that extend far beyond the initiating natural disaster. These consequences can include loss of life, large scale and indefinite population dislocation and uninsurable economic damage from the radiological
consequences:" 'Wildfire. According to the NCA (National Climate Assessment), increased heat and drought contribute to increases in wildfire frequency, and climate change has contributed to unprecedented wildfire events in the Southwest. The NCA projects increased heatwaves, drought risk, and more frequent and larger wildfires. Wildfires pose several risks to nuclear power plants, including increasing the potential for onsite fires that could damage plant infrastructure, damaging transmission lines that deliver electricity to plants, and causing a loss of power that could require plants to shut down. Wildfires and the smoke they produce could also hinder or prevent nuclear power plant personnel and supplies from getting to a plant.'
"Loss of offsite electrical power (#LOOP) to nuclear power stations is a leading contributor to increasing the risk of a severe nuclear power accident. The availability of alternating current (AC) power is essential for safe operation and accident recovery at commercial nuclear power plants. Offsite fires destroying electrical power transmission lines to commercial reactors therefore increase the probability and severity of nuclear accidents.
"For US nuclear power plants, 100% of the electrical power supply to all reactor safety systems is initially provided through the offsite power grid. If the offsite electrical grid is disturbed or destroyed, the reactors are designed to automatically shut down or 'SCRAM'. Onsite emergency backup power generators are then expected to automatically or manually start up to provide power to designated high priority reactor safety systems needed to safely shut the reactors down and provide continuous reactor cooling, pressure monitoring, but to a diminished number of the reactors’ credited safety systems. Reliable offsite power is therefore a key factor to minimizing the probability of severe nuclear accidents.
"The GAO identifies a number of US nuclear power plant sites that are vulnerable to the possible outbreak of wildfires where they are located. 'According to our analysis of U.S. Forest Service and NRC data, about 20 percent of nuclear power plants (16 of 75) are located in areas with a high or very high potential for wildfire,' the GAO report states. 'More specifically, more than
one-third of nuclear power plants in the South (nine of 25) and West (three of eight) are located in areas with a high or very high potential for wildfire.' The GAO goes on to identify 'Of the 16 plants with high or very high potential for wildfire, 12 are operating and four are shutdown.'"To analyze exposure to the wildfire hazard potential, the GAO used 2023 data from the U.S. Forest Service’s Wildfire Hazard Potential Map. 'High/very high' refers to plants in areas with high or very high wildfire hazard potential. Those #NuclearPower stations described by GAO as 'high / very high' exposure to wildfires and their locations are excerpted from GAO Appendix III: Nuclear Power Plant Exposure to Selected Natural Hazards.

"Wildfires can transport radioactive contamination from nuclear facilities
"A historical review of wildfires that occur around nuclear facilities (research, military and commercial power) identifies that these events are also a very effective transport mechanism of radioactivity previously generated at these sites and subsequently released into the environment by accident, spills and leaks, and careless dumping. The radioactivity is resuspended by wildfires that occur years, even decades later. The fires carry the radioactivity on smoke particles downwind, thus expanding the zone of contamination further and further with each succeeding fire. The dispersed radionuclides can have very long half-lives meaning they remain biologically hazardous in the environment for decades, centuries and longer."

Four days ago: #Spain Signals Openness to Keeping #NuclearPowerPlants Open
By Daniel Basteiro and Thomas Gualtieri
April 24, 2025"Spain is signaling for the first time that it’s open to reconsidering the shutdown of #NuclearPlants over the next decade amid a global revival of #AtomicEnergy.
While that’s not the plan agreed with nuclear plant operators, and it would be up to them to present concrete proposals, extensions are not ruled out, Environmental Transition Minister Sara Aagesen said in an interview." 'Nuclear energy will be present in our mix at least until 2035' but could go beyond that if companies propose extensions, which hasn’t happened yet, she said prior to an International Energy Agency summit on the future of energy security. 'We’re not considering anything because there is no specific proposal on the table.' "
Today [April 28th] "Spain's nuclear power plants automatically stopped, but diesel generators were activated to keep them in 'safe condition', officials said."

#Palisades power plant will restart. Here's where on the #GreatLakes #NuclearPlants operate
Story by Sarah Moore, Lansing State Journal, 2/27/2025
"Owners of Michigan's Palisades nuclear energy plant this week announced a new five-year program aimed at restarting the power station while adding two smaller, modular reactors to the existing facility.
"Holtec has launched 'Mission 2030,' a program to build America’s first small modular reactors — Holtec’s SMR-300 — at the Palisades site in Covert Township, Michigan, with a target of 2030 for first commercial operation.' Holtec International said in a release. "The new SMR-300s will be co-located with the existing 800-megawatt Palisades plant, which is on track to restart after an extended outage following shutdown in 2022.'
"The program was discussed at a ceremony Feb. 25, at which #Holtec said it has joined forces with #Hyundai Engineering & Construction to build a 10-gigawatt fleet of SMR-300s in North America, the release said.
"Nuclear energy production is seeing growing interest for power generation because it requires no fossil fuels and can help reduce greenhouse gases. The systems, however, generate tons of highly #RadioactiveWaste that has to be stored. In #Michigan, waste is stored within a short distance of the #GreatLakes in some locations."

From 2022. I'm guessing it was #RussianDrones
#Sweden #drones: Sightings reported over #NuclearPlants and palace
18 January 2022
"Days of sightings of drones over key Swedish sites including nuclear plants have prompted the country's security service to take the lead in an investigation.
"Three nuclear sites have been targeted and sightings have been reported over airports and the royal palace.
"Authorities have not speculated on who is behind the mysterious drones.
"Police and the coastguard are searching the sea and islands around Stockholm, local media reports say.
"The latest sightings on Monday evening involved a drone above the #ForsmarkNuclearPlant, but security agency Sapo said it was also investigating earlier drone flights near the #Ringhals and #Oskarshamn power plants. Police appealed to the public to come forward with information.
"Sapo said the drones were suspected of 'grave unauthorised dealing with secret information'.
"'The security service is conducting the investigation regarding the drone flights over our nuclear plants. Regarding other drone observations it's so far a matter for the police,' Sapo official Fredrik Hultgren told the BBC.
"He refused to give details about the type of drone, but they have been widely described as military-style and as having large wings.
"Swedish TV reported that a police helicopter was following a drone flying above it at a height of up to 1,000m (3,280ft) to the south-west and north-west of the capital Stockholm.
"According to the Aftonbladet news site, a drone was seen over the weekend circling the parliament and government buildings, as well as the royal palace in Stockholm. Drones were earlier spotted near Kiruna and Lulea airports.
"Prosecutors are keeping an open mind over who is behind the drone flights. They come at a time of increased military alert in Sweden because of tensions between #Russia and the West over the Russian military build-up near the borders of #Ukraine.
"Sweden has recently deployed troops to the Baltic island of Gotland in what officials describe as a signal that Sweden's military forces are ready to defend their territory.
"Sweden is not a member of the Nato defence alliance but said it was responding to three Russian landing craft moving into the Baltic Sea through Denmark's Great Belt Strait."

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."

#NRC Fines #Holtec Once Again - Red Flags for #OysterCreek
January 28, 2022
Media Contact: [email protected]
"Holtec Decommission International was fined again by the Nuclear Regulatory Commission. Holtec agreed to pay a $50,000 fine after the plant’s armorer #falsified documents at the #OysterCreekNuclearPlant in #LaceyTownship. According to the NRC investigation, the agency found that the plant’s armorer failed to perform mandatory firearms inspections and falsified related records. This is the second fine in two months for Holtec. In December, the company agreed to pay a $150,000 penalty for security related violations, however this time neither NRC nor Holtec disclosed the details of the violation due to the sensitivity of it.
“This is the second time in two months that Holtec has been fined for security related violations for the former Oyster Creek #NuclearPlant. It's the latest red flag in a series of red flags when it comes to Holtec. These violations should be an alarm bell going off for NRC not just to hold Holtec accountable, but to intervene in Holtec’s security and management of the site. It’s good that NRC conducted investigations and penalized Holtec, however that is clearly not enough, as this continues to happen,' said Anjuli Ramos-Busot, New Jersey Director of the Sierra Club.
"The public is concerned about Holtec’s plan to move still-hot nuclear waste out of water pools and into dry cask storage in half the usual time, typically 5 years. They claim their casts are proprietary and have not disclosed details about their design to the public. Until the rods are out of the spent-fuel pools and put into dry cask storage, the plant is extremely vulnerable. If there is a power outage, storm surge, or flood, the rods could melt down and create serious public health and environmental damage.
“The NRC and New Jersey must make sure there is proper oversight and to ensure Holtec is following safety protocols. This area is impacted by sea-level rise and climate change. During Sandy, the floodwaters came up onto the site at Oyster Creek. Storing nuclear waste in a site that already presents safety flaws is incredibly dangerous. If Holtec isn’t storing nuclear rods correctly, it could lead to major public health and environmental problems. That is why we need to make sure Holtec is not cutting corners [because as we all know, Holtec gets to keep what it doesn't spend] and will ensure transparency,' said Anjuli Ramos-Busot, New Jersey Director of the Sierra Club."

A timeline of incidents at #Palisades #Nuclear Power Plant since 2007
Published: May. 12, 2013
"COVERT TOWNSHIP, MI -- The leak that shut down Palisades Nuclear Power Plant May 5 is one of a series of incidents that have bedeviled the nuclear reactor in recent years.
"#Entergy Corp. bought Palisades from Consumers Energy in 2007 for $380 million. The one-reactor plant, which is located along #LakeMichigan in #CovertTownship, supplies about 20 percent of the utility's power. The facility came online in 1971 and its license runs until 2031 [it was decommissioned in 2022].
"Below is a timeline of incidents at Palisades since 2007, based on NRC reports and previous MLive/Kalamazoo Gazette articles.
2007 -- Palisades' head of security resigned amid revelations he had fabricated some of his credentials.
2008 -- An NRC safety assessment found Palisades failed "to recognize and assess the impact of radiological hazards in the workplace." The NRC found that Palisades failed to determine how much radiation employees were exposed to after radiation monitors worn by the workers warned of an exposure.
August 2008 -- Five workers were trapped for 90 minutes inside a high-temperature area when a hatch malfunctioned. The NRC launched a probe and found the plant did not take proper precautions to prevent such occurrences.
2009 -- During an inspection, the NRC found that workers failed to notice a problem in the pool where spent fuel rods are kept. The finding, labeled a "low to moderate safety" risk that did not endanger the public, kept Palisades on the NRC's list of plants that required additional regulatory oversight for a second year. The plant's 2009 safety assessment also found problems with human performance regarding "error-prevention techniques."
May 2010
-- A Palisades manager left the control room without following protocol and the event was not reported within 24 hours, the NRC found.January 2011
-- Palisades operated at 55 percent power for eight days after a cooling-water pump lost power when an electrical bus failed. The event did not represent a threat to health and safety, the NRC said.May 2011
-- While NRC inspectors were conducting a routine test of the plant’s auxiliary feed water system, a turbine-driven pump was tripped. Investigators found a component of the pump that was greased and should not have been. The NRC classified the event as a "low to moderate" safety significance.August 2011
-- The NRC launched a special inspection after the failure of a coupling that holds pipes together. It found Palisades did not follow industry standards when choosing the coupling and the cracking was preventable. Palisades replaced all couplings.September 2011
-- Palisades shut down between Sept. 16 and Sept. 20 for repairs, after workers discovered a leaking valve in the system that cools the reactor.September 2011
-- Palisades shut down for a week after a breaker fault in the plant's electrical system Sept. 25, when a worker performing maintenance on an electrical panel when a piece of metal came into contact with another metal piece and caused an arc. There were no injuries reported. The NRC launched a special investigation, the second in two months. The investigation found that during the incident, which it named of "substantial significance to safety," Palisades did not follow proper safety protocols before the shutdown.November 2011
-- The NRC bumped Palisades down a level to the Regulatory Response column as a result of the May 2011 incident.January 2012
-- Palisades shut down for 3-1/2 days to repair a wearing seal on a control rod mechanism.February 2012
-- The NRC downgraded Palisades to the third regulatory column, making it among the four-worst performing reactors in the U.S. The downgrade came as a result of the two special investigations launched in 2011.June 2012
-- Palisades shut down for a month to repair a leak in its safety injection refueling water tank. Numerous cracks were found within the 300,000-gallon storage tank, according to reports. When the plant returned to service, the tank was still leaking, but due to its size, it did not pose a safety risk, the NRC found.July 2012
-- An independent review of Palisades found "examples of a lack of accountability at all levels."
The study, conducted by Conger & Elsea Inc. in January and February 2012, looked at plant operations related to human performance, safety-conscious work environment, problem identification and resolution.August 2012
-- Palisades shut down for 18 days to repair a leak in the control rod mechanism drive in the containment building. The NRC sent a three-inspector team and launched a special inspection of the pressure-boundary leak. During the 30 days before the location of the leak was discovered, up to 10,000 gallons of radioactive water leaked from the containment vessel. The water was contained and did not pose a safety risk to the public, the NRC found.September 2012
-- An NRC inspector found what it characterized as a small leak in a valve in the service water system. The water was not radioactive and did not represent a health or safety risk, the NRC said.November 2012
-- Palisades shuts down for three days to repair a steam leak inside the plant's auxiliary building.November 2012
-- The NRC upgraded Palisades after an 11-day inspection in September found that Entergy had made improvements and addressed deficiencies. The NRC ordered an additional 1,000 hours of inspections in 2013, on top of the standard 2,000 hours.February 2013
-- Palisades shut down for six days to repair a leak in the component cooling water system. It was leaking 35 gallons of non-radioactive water an hour before the shutdown, the NRC said. The leak did not represent a threat to the public or the plant, the NRC said.March 2013
-- Palisades was one of three U.S. plants with significant safety events, or "near-misses" in the past three years, according to a report by the independent Union of Concerned Scientists. The near-misses at Palisades resulted from long-standing problems, the UCS said, and it charged the NRC with failing to enforce violations.May 2013
-- On May 5, Palisades shut down after the leak in the safety injection refueling water tank accelerated from one a day to 90 gallons within a 24-hour period, the NRC said. On May 4, before the shutdown, some 79 gallons of radioactive water from the tank went down a drain into a capture basin, where it was extremely diluted, according to the NRC, and ended up in Lake Michigan. The NRC has sent an additional inspector to Palisades, and one of its health physicists is also investigating the incident. As of May 10, Palisades was still offline while workers and inspectors search for the source of the leak and make repairs."Source:

#Palisades #nuclear plant gets $150 million in #Michigan budget
By Sheri McWhirter, Jul. 03, 2023
"Michigan lawmakers included $150 million toward the effort to restart the Palisades nuclear plant as part of a record $81.7 billion state budget passed last week.
"State officials contributed the millions in taxpayer dollars toward #Holtec International’s effort to get the nuclear plant upgraded and fired back up to provide 800 megawatts of carbon-free, base load power as the energy sector transitions away from fossil fuels. If it happens, it would be the first nuclear plant nationwide to return to generating power after being decommissioned.
"The plant was closed last year when its fuel ran out and the owner sold the facility to Holtec. The new owner has now twice applied for federal money to help get the plant operational again.
"The Biden administration has a $6 billion fund within the U.S. Department of Energy intended to preserve the U.S. nuclear reactor fleet and energy sector jobs.
"[...] Power generation at nuclear plants does not generate greenhouse gas emissions that drive climate change, like burning fossil fuels does. However, some #environmental advocates remain concerned about ecological #degradation from needed #uranium #mining and #radiation risk from #ToxicWaste nuclear plants produce."

#Seabrook #nuclear plant faces ongoing challenge of managing concrete degradation
by Angeljean Chiaramida, July 12, 2023
"A 2023 report shows concrete degradation has expanded from seven to 10 structures at the Seabrook plant.
"Discovered and reported by NextEra’s personnel in 2009, #ASR is a slow-developing type of degradation that can occur in some #concrete when moisture is present. Found most often in dams and bridges, ASR manifests as micro-cracking, staining, expansion and deformation of concrete.
"So far, the #NRC’s repeated inspections determined ASR in Seabrook Station’s structures poses no immediate threat to public safety."
