Safety of SanOnofre nuclear waste storage is disputed

Dust-UPS Continue Over Radioactive Waste Storage at San Onofre https://goodmenproject.com/featured-content/dust-ups-continue-over-radioactive-waste-storage-at-san-onofre/   The most recent dispute centers on the green light the California Coastal Commission gave Edison on July 16 to remove the cooling pools where spent fuel rods were submerged for several years to begin cooling down. October 25, 2020 by EarthTalk  By Sarah Mosko

The decommissioning of San Onofre Nuclear Generating Station (SONGS) has been riddled with controversies since it was shuttered in 2013, undermining public confidence in Southern California Edison’s management of highly radioactive nuclear waste which will be stored on-site for the foreseeable future.

In 2018 for example, a whistleblower exposed how a 54-ton canister loaded with radioactive waste nearly plummeted 18 feet because of a design flaw and human error, prompting the Nuclear Regulatory Commission (NRC) to cite Edison with the most serious violation ever imposed on a spent fuel licensee.

The most recent dispute centers on the green light the California Coastal Commission gave Edison on July 16 to remove the cooling pools where spent fuel rods were submerged for several years to begin cooling down. Edison argued the pools aren’t needed anymore because the rods have all been transferred into dry storage canisters.

Each of SONGS’s 123 canisters holds roughly the same amount of Cesium-137 as released during the 1986 Chernobyl disaster.

At issue is this: If a canister were to begin degrading, creating risk of radiation release, returning it to the cooling pools is the only means whereby the contents could be repackaged into a new canister. Nonetheless, Edison convinced the Coastal Commission that an untested, unapproved nickel “cold spray” overlay technology could be applied to patch degrading canisters, making the cooling pools unnecessary.

NRC spokesperson David McIntyre confirmed that NRC has neither evaluated nor approved any method for fixing a canister. The only sure solution is to replace the canister. Many nuclear safety advocates in Orange and San Diego counties are outraged, believing Edison, the Coastal Commission, and NRC are gambling public safety on unproven repair methodology piggy-backed on already inferior dry storage canisters that need to last far longer than originally intended.

This situation is only partly due to the federal government’s failure to construct a mandated permanent national repository for storing the country’s highly radioactive nuclear waste, leaving U.S. nuclear plants saddled with storing spent fuel on-site indefinitely.

Objections to eliminating the pools revolve around this specter of stranded radioactive waste remaining on-site for the foreseeable future, with no means to repackage it, together with concerns about the canisters Edison chose and SONGS’s beachfront location.

Inferior Storage Canisters

SONGS uses two models of thin-walled (5/8 inch thick), welded shut, stainless steel canisters (Holtec and Areva). They are warranted only for manufacturing defects and for just 10-25 years. Thick-walled casks (10-19 inch) with bolted lids, as survived the Fukushima earthquake and tsunami, are standard throughout most of the world.

Nuclear safety advocates point to evidence thin-walled canisters are vulnerable to cracking yet can’t be inspected for tiny cracks which can grow through the canister wall. They are critical of NRC for ignoring established safety codes for nuclear pressure vessels used for storage and transport of nuclear waste (American Society of Mechanical Engineers, ASME N3) when they approved SONGS’s canisters which can’t be inspected by proven methodology (liquid penetrant).

Instead, Edison applied a robotic camera in 2019 to eight Holtec canisters to characterize the extent of canister scraping/gouging incurred during downloading into their holes in the in-ground concrete storage pad. Because of the small clearance between a canister and the guide ring at the mouth of the hole, canisters are routinely scraped/gouged, potentially initiating cracking.

Edison admitted their improvised camera technique doesn’t qualify as a formal inspection, yet the NRC accepted Edison’s conclusion that damage to the canisters during downloading poses no current credible threat.

Thin-walled canisters also fail to block gamma or neutron radiation so require additional individual thick concrete containers for storage and thick metal containers for transport. The unsealed steel lined concrete containers require air vents for convection cooling.

Marine Environment

SONGS is situated within 50 miles of 8 million people, sandwiched between the ocean and the I5 Freeway, and accessible to terrorist attack from either side. A mysterious two-night swarm of drones over the Palo Verde nuclear plant in Arizona last September highlights vulnerability to malfeasance.

SONGS sits 108 feet from shore in a known earthquake zone, creating risks of flooding from sea level rise and shaking and tsunamis from earthquakes. The in-ground pad holding the Holtec canisters already sits just 18 inches above the water table.

Warnings on releasing Fukushima’s radioactive water into the Pacific Ocean

Warning over Fukushima nuclear power plant water release, 7 News,  CNN,  Allie Godfrey,  Sunday, 25 October 2020 Contaminated water that could soon be released into the sea from the Fukushima Daiichi nuclear power plant contains radioactive carbon with the potential to damage human DNA, environmental rights organisation Greenpeace has warned.

The environmental group claims that the 1.23 million metric tons of water stored at the plant – scene of the 2011 Fukushima Daiichi nuclear disaster – contains “dangerous” levels of the radioactive isotope carbon-14 and other “hazardous” radionuclides, which it says will have “serious long-term consequences for communities and the environment” if the water is released into the Pacific Ocean.

To cool fuel cores at the damaged Fukushima nuclear plant operator Tokyo Electric Power Company (TEPCO) has pumped in tens of thousands of tons of water over the years. Once used, the water is put into storage.

But nine years on from Japan’s worst nuclear disaster, storage space is running out, and the government is still deciding what to do with the water.

Authorities, including the country’s environment minister, have indicated the only solution is to release it into the ocean – a plan facing opposition from environmental campaigners and fishing industry representatives.

On Friday, the Japanese government postponed a decision on what to do with the water. ……….“Any radioactive discharge carries some environmental and health risk,” Francis Livens, a professor of radiochemistry at the University of Manchester told CNN, adding that the risk would be relative to how much carbon 14 would be released into the ocean. “An awful lot really does depend on how much is going to be discharged.”

“If it’s (carbon-14) there and it’s there in quantity, yes, there probably is a risk associated with it,” Livens, who is not associated with the Greenpeace study, said. “People have discharged carbon-14 into the sea over many years. It all comes down to how much is there, how much is dispersed, does it enter marine food chains and find its way back to people?”……..

Corkhill told CNN the contaminated water is becoming a pressing concern: If the Japanese government does not deal with the contaminated water, it will have “several millions of cubic meters of water that’s radioactive all sat on the Fukushima site,” she said. https://7news.com.au/technology/warning-over-fukushima-nuclear-power-plant-water-release-c-1453141

Pacific islands demand truth on the decades of nuclear testing, now that nuclear weapons are becoming illegal

Guardian 25th Oct 2020, Now that nuclear weapons are illegal, the Pacific demands truth on decades of testing. Nuclear weapons will soon be illegal. Just over 75 years since their devastation was first unleashed on the world, the global community has rallied to bring into force a ban through the Treaty on the Prohibition of Nuclear Weapons.

Late on Saturday night in New York, the 50th country – the central American nation of Honduras – ratified the treaty. It will become international law in 90 days. For many across the Pacific region, this is a momentous achievement and one that has been long called
for. Over the second half of the 20th century 315 nuclear weapons tests were conducted by so-called “friendly” or colonising forces in the Marshall Islands, Kiribati, Australia and Maohi Nui (French Polynesia).

The United States, Britain and France used largely colonised lands to testtheir nuclear weapons, leaving behind not only harmful physical legacies but psychological and political scars as well. Survivors of these tests and their descendants have continued to raise their voices against these weapons. They are vocal resisters and educators, the reluctant but intense knowledge holders of the nuclear reality of our region.

US urges countries to withdraw from UN nuclear ban treaty

US urges countries to withdraw from UN nuke ban treaty,  By EDITH M. LEDERER, October 22, 2020, UNITED NATIONS (AP) — The United States is urging countries that have ratified a U.N. treaty to ban nuclear weapons to withdraw their support as the pact nears the 50 ratifications needed to trigger its entry into force, which supporters say could happen this week.The U.S. letter to signatories, obtained by The Associated Press, says the five original nuclear powers — the U.S., Russia, China, Britain and France — and America’s NATO allies “stand unified in our opposition to the potential repercussions” of the treaty……..

Beatrice Fihn, executive director of the International Campaign to Abolish Nuclear Weapons, the 2017 Nobel Peace Prize-winning coalition whose work helped spearhead the nuclear ban treaty, told The Associated Press Tuesday that several diplomatic sources confirmed that they and other states that ratified the TPNW had been sent letters by the U.S. requesting their withdrawal.

She said the “increasing nervousness, and maybe straightforward panic, with some of the nuclear-armed states and particularly the Trump administration” shows that they “really seem to understand that this is a reality: Nuclear weapons are going to be banned under international law soon.”

Fihn dismissed the nuclear powers’ claim that the treaty interferes with the Nuclear Nonproliferation Treaty as “straightforward lies, to be frank.”

“They have no actual argument to back that up,” she said. “The Nonproliferation Treaty is about preventing the spread of nuclear weapons and eliminating nuclear weapons, and this treaty implements that. There’s no way you can undermine the Nonproliferation Treaty by banning nuclear weapons. It’s the end goal of the Nonproliferation Treaty.”

The NPT sought to prevent the spread of nuclear arms beyond the five original weapons powers. It requires non-nuclear signatory nations to not pursue atomic weapons in exchange for a commitment by the five powers to move toward nuclear disarmament and to guarantee non-nuclear states’ access to peaceful nuclear technology for producing energy………

“That the Trump administration is pressuring countries to withdraw from a United Nations-backed disarmament treaty is an unprecedented action in international relations,” Fihn said. “That the U.S. goes so far as insisting countries violate their treaty obligations by not promoting the TPNW to other states shows how fearful they are of the treaty’s impact and growing support.”

The treaty was approved by the 193-member U.N. General Assembly on July 7, 2017 by a vote of 122 in favor, the Netherlands opposed, and Singapore abstaining. Among countries voting in favor was Iran. The five nuclear powers and four other countries known or believed to possess nuclear weapons — India, Pakistan, North Korea and Israel — boycotted negotiations and the vote on the treaty, along with many of their allies…………  https://apnews.com/article/nuclear-weapons-disarmament-latin-america-united-nations-gun-politics-4f109626a1cdd6db10560550aa1bb491

Shadow of $25 billion Nuclear Plant Vogtle hangs over Georgia Public Service Commission elections

Nuclear costs loom over races for Georgia PSC races
Public Service Commission must deal with $25 billion Plant Vogtle’s impact on electric rates, News 4 Ajax, Jeff Amy, Associated Press,  25 Oct 20,  ATLANTA – The shadow of two nuclear reactors that Georgia Power Co. is building near Waynesboro hangs over two statewide elections for the Georgia Public Service Commission. Although the reactors are now getting so close to completion that they are likely to enter service, whoever is elected will have to deal with the $25 billion project’s ultimate impact on customer bills.

Electric customers statewide and even in Jacksonville will help pay for Plant Vogtle, as Georgia Power has contracts to provide power from the plant around the Southeast.

The five-person utility regulatory body is currently all Republican, with two members up for reelection this year. ………..

Amid rising costs, the plan to add a third and fourth nuclear reactor at Plant Vogtle survived a cost-overrun scare in 2018 with the heavy support of the state’s Republican establishment. Georgia Power, the largest subsidiary of the Atlanta-based Southern Co. is now building the only new nuclear plants in the U.S.  ……… https://www.news4jax.com/news/georgia/2020/10/25/nuclear-costs-loom-over-races-for-georgia-utility-regulator/

Legal fight to stop Sizewell nuclear project destroying an historic Suffolk woodland

East Anglian Daily Times 24th Oct 2020, Campaigners have agreed to continue their battle to stop an historic
Suffolk woodland from being felled – and are taking the fight to the
Court of Appeal.
EDF is preparing to cut down the 100-year-old Coronation
Wood in order to use the land and Pillbox Field to relocate some Sizewell B
buildings ready for a start on Sizewell C.
However, TASC (Together Against
Sizewell C) says the project is premature because the twin reactor nuclear
power station has yet to receive planning permission. TASC has now applied
to Court of Appeal following the High Court’s dismissal of supporter Joan
Girling’s bid for a judicial review application of the planning consent
earlier this month. Joan Girling said, ‘‘The Planning Inspectorate has
now accepted EdF’s recently submitted Sizewell C DCO application.
However, it remains our view that permission for Sizewell C is not a
foregone conclusion. “There is no certainty that it will be given
approval. Until such time that the Sizewell C application is determined, it
is the view of many people that the needless destruction of Coronation Wood
should not go ahead.

USA government puts out a financial lifeline to the failing nuclear industry

Nuclear Energy Granted A State-Sponsored Lifeline In The U.S. Oil Price By Haley Zaremba – Oct 24, 2020  For the past several decades, the United States has been the poster child for the ailing state of the nuclear industry. The nuclear sector in the U.S. is plagued by aging infrastructure, mounting debts, dependence on government handouts, and the staggering cost of maintaining spent nuclear fuel. What’s more, it’s had to compete with the homegrown shale revolution, and expensive nuclear is simply no match for the tidal wave of cheap shale oil and gas that came flooding out of the West Texas Permian Basin.The United States has long been the single-biggest generator of nuclear power in the world, accounting for a whopping third of global nuclear energy production. However, that status will likely soon be stripped away as the United States has seen one nuclear plant after another shutter after struggling and failing to stay in the black, at the same time that other nations have pushed their nuclear programs forward with rapid rates of expansion. China, in particular, has invested huge sums into building up its nuclear program, and is on track to overtake France and then the United States to become the new biggest nuclear power producer on the planet.

But the winds of change could soon be blowing for U.S. nuclear. Last month the nuclear sector got a small but certainly not insignificant state-sponsored lifeline when the the Department of Energy (DOE) announced that “it would be awarding more than $65m in nuclear energy research, crosscutting technology development, facility access, and infrastructure awards.” According to reporting by PowerTechnology, “the awards fall under the department’s nuclear energy programs – the Nuclear Energy University Programme, the Nuclear Energy Enabling Technologies, and the Nuclear Science User Facilities.”

And now, just this week, there’s even better news for U.S. nuclear power. “After hemming and hawing for decades, the United States is taking some big steps in developing advanced nuclear reactor technologies,” Forbes reported on Wednesday. The article is referring to yet another major announcement from the DOE that took place just last week. The department will be awarding $80 million each–and that’s just in initial funding–to two different teams under the Advanced Reactor Demonstration Program (ARDP). The DOE has planned for an additional $3.2 billion in investment over the next seven years, an impressive sum that will be matched by the private sector within the nuclear industry. One of these teams is to be led by Bill Gates’ brainchild TerraPower in a joint effort with GE Hitachi. The other will be spearheaded by X-energy. …….https://oilprice.com/Alternative-Energy/Nuclear-Power/Nuclear-Energy-Granted-A-State-Sponsored-Lifeline-In-The-US.html

UN Treaty on the Prohibition of Nuclear Weapons reaches the required 50 ratifications to become law

Historic milestone: UN Treaty on the Prohibition of Nuclear Weapons reaches 50 ratifications needed for entry into force https://www.icanw.org/historic_milestone_un_treaty_on_the_prohibition_of_nuclear_weapons_reaches_50_ratifications_needed_for_entry_into_force  25 Oct 20, 

On October 24, 2020, the UN Treaty on the Prohibition of Nuclear Weapons reached the required 50 states parties for its entry into force, after Honduras ratified just one day after Jamaica and Nauru submitted their ratifications. In 90 days, the treaty will enter into force, cementing a categorical ban on nuclear weapons, 75 years after their first use.

This is a historic milestone for this landmark treaty. Prior to the TPNW’s adoption, nuclear weapons were the only weapons of mass destruction not banned under international law, despite their catastrophic humanitarian consequences. Now, with the treaty’s entry into force, we can call nuclear weapons what they are: prohibited weapons of mass destruction, just like chemical weapons and biological weapons.

ICAN’s Executive Director Beatrice Fihn welcomed the historic moment. “This is a new chapter for nuclear disarmament. Decades of activism have achieved what many said was impossible: nuclear weapons are banned,” she said.

Setsuko Thurlow, survivor of the atomic bombing of Hiroshima, said “I have committed my life to the abolition of nuclear weapons. I have nothing but gratitude for all who have worked for the success of our treaty.” As a long-time and iconic ICAN activist who has spent decades sharing the story of the horrors she faced to raise awareness on the humanitarian consequences of nuclear weapons this moment held particular significance: “This is the first time in international law that we have been so recognized. We share this recognition with other hibakusha across the world, those who have suffered radioactive harm from nuclear testing, from uranium mining, from secret experimentation.” Survivors of atomic use and testing all over the world have joined Setsuko in celebrating this milestone.

The three latest states to ratify were proud to be part of such a historic moment. All 50 states have shown true leadership to achieve a world without nuclear weapons, all while facing unprecedented levels of pressure from the nuclear armed states not to do so. A recent letter, obtained by AP only days before the ceremony, demonstrates that the Trump administration has been directly pressuring states that have ratified the treaty to withdraw from it and abstain from encouraging others to join it, in direct contradiction to their obligations under the treaty. Beatrice Fihn said: “Real leadership has been shown by the countries that have joined this historical instrument to bring it to full legal effect. Desperate attempts to weaken these leaders’ commitment to nuclear disarmament demonstrate only the fear of nuclear armed states of the change this treaty will bring.”

This is just the beginning. Once the treaty is in force, all states parties will need to implement all of their positive obligations under the treaty and abide by its prohibitions. States that haven’t joined the treaty will feel its power too – we can expect companies to stop producing nuclear weapons and financial institutions to stop investing in nuclear weapon producing companies.

How do we know? Because we have nearly 600 partner organisations in over 100 countries committed to advancing this treaty and the norm against nuclear weapons. People, companies, universities and governments everywhere will know this weapon has been prohibited and that now is the moment for them to stand on the right side of history.

The Atlantic raised the big question. In a crisis, do Americans want Trump’s finger on the nuclear button?

The Atlantic’s endorsement of Joe Biden raises a sobering point all Americans should consider. Daily Kos, Dartagnan Community, Friday October 23, 2020   “……….   —The Atlantic reminds us that the person in charge of this country’s nuclear arsenal matters.

In most matters related to the governance and defense of the United States, the president is constrained by competing branches of government and by an intricate web of laws and customs. Only in one crucial area does the president resemble, in the words of the former missile officer and scholar Bruce Blair, an absolute monarch—his control of nuclear weapons. Richard Nixon, who was president when Major Hering asked his question, was reported to have told members of Congress at a White House dinner party, “I could leave this room and in 25 minutes, 70 million people would be dead.” This was an alarming but accurate statement.

When contemplating their ballots, Americans should ask which candidate in a presidential contest is better equipped to guide the United States through a national-security crisis without triggering a nuclear exchange, and which candidate is better equipped to interpret—within five or seven minutes—the ambiguous, complicated, and contradictory signals that could suggest an imminent nuclear attack. These are certainly not questions that large numbers of voters asked themselves in 2016, when a transparently unqualified candidate for president won the support of 63 million Americans..
The presidency is much more than a “position” to be filled from time to time. As we have all bitterly learned from the pandemic, the implications of a manifestly unfit president are profound and potentially lethal to millions of Americans. To provide someone proven to be as erratic and delusional as Donald Trump with the power to end all of our lives by initiating (or reacting to) a potential nuclear attack is simply insane. Americans may not have known exactly what they were putting into the Oval Office in 2016, but there is no such excuse now. We’ve all seen the movie, and it ends in death.
That crisis—or something close to it— is bound to come, whether we want to acknowledge it or not.  So Americans need to ask themselves who they really trust to make that call when it happens, and whether they really want those fat little fingers so close to that red button. ·https://www.dailykos.com/stories/2020/10/22/1988590/-The-Atlantic-s-endorsement-of-Joe-Biden-raises-a-sobering-point-all-Americans-should-consider

Donald Trump and Joe Biden on climate change

Independent 23rd Oct 2020 It has been around 20 years since a lengthy discussion on climate change featured in a presidential debate during which time a monumental shift has happened in how America views the crisis.

Two-thirds of Americans think that the US government should do more on climate change and moderator Kristen Welker asked both Donald Trump and Joe Biden how they would step up
on the issue during the final presidential debate on Thursday, with millions of Americans already taking to the polls ahead of election day on 3 November.

Calling it an “existential crisis”, Mr Biden sounded the alarm for the world to address global warming, as Mr Trump took credit for pulling the US out of the 2015 Paris Climate Accord, the international agreement aimed at doing precisely that. Mr Trump said his focus was saving
American jobs, while taking credit for some of the “cleanest air and water the nation has seen in generations” — partly down to regulations passed in the Obama era.

https://www.independent.co.uk/environment/climate-change-presidential-debate-biden-trump-windmill-fracking-b1242172.html

Independent 23rd Oct 2020, President Trump, who has repeatedly called climate change a  “hoax”, said he planned for a “trillion trees” before touting America’s “clean air”, “clean water” and lower carbon emissions (all of which are, at best, misleading, as The Independent has reported).

The president then pivoted to an attack on clean energy, taking particular issue with windmills. “He thinks wind causes cancer. Windmills,” Mr Biden noted. “I know more about wind than you do,” Mr Trump replied, before going on to say windmills are extremely expensive, “kill all the birds” and “the fumes coming up, if you’re a believer in carbon emission … for these massive windmills is more than anything we’re talking about with natural gas which is very clean”.

Climate change a big threat to nuclear reactors – as water supplies at risk

Climate change poses big water risks for nuclear, fossil-fueled plants, S and P Global, Esther Whieldon Taylor Kuykendall, 23 Oct 20,

Exelon Corp.’s Clinton Power Station nuclear plant in Illinois uses about 248.5 billion gallons of water annually, the utility said in its 2020 report to CDP.to CDP. The plant is in an area projected to face increased water stress by 2030.
As global warming climbs and humanity’s water consumption increases, nuclear and fossil-fueled power plants that rely on freshwater for cooling may not be able to perform at their peak capacity or could be forced to shut down temporarily even as demand for their supplies for indoor cooling and other uses increase, according to researchers and industry experts.
Climate change-exacerbated water shortage issues pose a near-term and longer-term performance risk to power plants, such as hydropower and nuclear, around the world. And in the Lower 48, more than half of the fossil-fueled and nuclear fleet is located in areas forecast to face climate-related water stress by the end of this decade under a business-as-usual scenario, according to an analysis by S&P Global Market Intelligence.

But electric utilities’ overall exposure to power plant water stress risks could diminish as they pursue decarbonization strategies and replace water-dependent plants with wind and solar generation that require little to no water. Some companies are also implementing water management and related investment strategies to reduce their exposure. ……..

According to projections from the World Resources Institute’s Aqueduct Water Risk Atlas, water stress — when humanity’s competition for water exceeds the rate at which nature can replenish its stocks — could grow materially by 2030 in the drought-prone Western U.S., as well as the upper Midwest and portions of the Northeast and Florida, due to climate change.

About 61.8% of existing fossil-fueled and nuclear power plants in the Lower 48, or a combined 535 GW of operating capacity, is in areas that could face medium-high to extremely high water stress in 2030, based on an analysis of Market Intelligence’s power plant data paired with the Aqueduct water stress projections.

Moreover, 68.6% of the Lower 48’s natural gas-fired fleet, 73.3% of its oil-fueled fleet, 61.0% of its nuclear fleet, and 44.6% of its coal-fired fleet are in areas expected to face medium-high to extremely-high water stress that year.

“As we’re seeing snowpack decline — a natural mountainous reservoir of water — and as we’re getting lower amounts of total precipitation and available water in the U.S. West, this is going to be a really serious issue for the power sector,” said Betsy Otto, director of the Global Water Program at the World Resource Institute, or WRI. Moreover, scientists have said the West is entering a megadrought that could last more than 20 years.

Otto also noted that several other U.S. regions not normally thought of as facing water supply issues are already experiencing chronic water challenges that, if left unchecked, could become a problem if extended droughts, heatwaves, and other major extreme weather events should occur.

A number of utilities use WRI’s Aqueduct tool to assess their water risks in their annual reports to the CDP, formerly known as the Carbon Disclosure Project, and other organizations. But those reports typically focus on the WRI’s current water stress models and not the tool’s future climate projections.

WRI’s current water stress models show a number of regions that are facing water stress will be in the same situation, or worse, at the end of the decade.

Along those lines, Moody’s Investors Service in August reported that about 48 GW of nuclear capacity across the U.S. face elevated exposure to combined heat and water stress, including plants owned by Exelon Corp., Vistra Corp., Entergy Corp., and the Arizona Public Service Co.

In hot water

A plant’s location is not the only factor that will determine its vulnerability to water stress. A plant’s water source, cooling technology and the temperature of the water when it is withdrawn are also key factors, according to scientific reports. The Market Intelligence analysis using the WRI tool does not account for those three factors.

In addition, rising ambient air and water temperatures can also create operational and legal issues for plants. Because plants primarily use water to cool their systems, “if that water is hot or warmer to start with, that’s not so good. That makes the power plant less efficient” and it also means the plant risks violating federal restrictions on how hot water can be when it is discharged, said Auroop Ganguly, director of the Northeastern University College of Engineering Sustainability and Data Sciences Laboratory.

Ganguly co-authored a study that found that by the 2030s, climate-induced water stress in the form of increased water temperatures and limited freshwater supplies will hurt the power production of thermoelectric plants in the South, Southwest, West and West North Central regions of the U.S. According to the 2017 study, U.S. nuclear and fossil-fueled plants at that time used about 161 billion gallons per day, or 45% of the nation’s daily freshwater usage, 90% of which was for cooling.

The technologies used by a power plant can also make a big difference in how much water it needs. Dry-cooling technology uses very little water but is costlier and less efficient than alternatives. And while once-through cooling systems withdraw more water than recirculating systems, once-through cooling returns nearly all of the water to the source while recirculating systems consume more water due to evaporation………. https://www.spglobal.com/marketintelligence/en/news-insights/blog/street-talk-episode-69-banks-left-with-pockets-full-of-cash-and-few-places-to-go

Fossil fuels are ”very clean” – Donald Trump

Guardian 23rd Oct 2020, In Donald Trump’s world – laid bare during Thursday night’s final
presidential debate with his Democratic rival Joe Biden in Nashville – fossil fuels are “very clean”, the US has the best air and water despite his administration’s extensive regulatory rollbacks, and thecountry can fix climate change by planting trees.
But according to the harsh realities being laid out by climate scientists, Trump’s world does
not exist. Humanity has just eight years to figure out how to get climate change under control before the future starts to look drastically worse – multiple-degree temperature increases, global sea-level rise, and increasingly disastrous wildfires, hurricanes, floods and droughts. Doing so will mean that unless there is a technological miracle, humans will at some point have to stop burning oil, gas and coal.https://www.theguardian.com/us-news/2020/oct/23/joe-biden-transition-from-oil-industry-rowing-back
