Small Modular Reactors 3
https://www.youtube.com/watch?v=XECq9uFsy6o Sabine has quite a sense of humour, excellent common sense, and in my view is right on most topics. Also on the current reality of modular reactors. But not on nuclear power generally or on renewables -- she after all trained as a particle physicist rather than a nuclear physicist, and does not really understand the practical effects of the complexity of radioactive decay products.

SA's Unscientific Nuclear Discourse 2
https://www.businesslive.co.za/bd/opinion/2024-11-01-neil-overy-weaponising-science-in-sas-nuclear-discourse/ Dr NEIL OVERY: Weaponising science in SA¡¯s nuclear discourse The denigration of other disciplines or voices is dangerous as nuclear power poses so many questions that science cannot answer BL Premium 01 November 2024 - 05:00 by Neil Overy During her welcoming speech at last month¡¯s Nuclear Energy Summit hosted by the department of electricity & energy in Tshwane, Princy Mthombeni, one of SA¡¯s most vocal nuclear boosters, referenced author Chimamanda Ngozi Adichie¡¯s observation that it is dangerous to reduce anything to a single story, reminding those present of ¡°the importance of embracing diverse perspectives¡±. Speaking at the summit, both electricity & energy minister Kgosientsho Ramokgopa and his deputy, Samantha Graham-Mar¨º, continued on this theme by emphasising that the government was intent on engaging properly with all stakeholders when it comes to nuclear power. For example, Graham-Mar¨º stated that ¡°our ministry is not going to compromise on public participation ... openness and transparency ... we need to work together¡±. ADVERTISING Unfortunately, and clearly quite intentionally, rather than embracing ¡°diverse perspectives¡± and ¡°public participation¡±, the summit did the exact opposite. Not only were representatives of civil society entirely excluded from the summit, but both Graham-Mar¨º and Ramokgopa made it clear that they had little interest in opinions about nuclear power that were contrary to theirs or the government¡¯s. Graham-Mar¨º came straight to the point in her address by stating that opponents of nuclear power in SA are simply ¡°ignorant¡±. Ramokgopa drank even deeper from the well of ad hominin attacks, noting that opponents of nuclear power ¡°live in the mud¡± because they ¡°soil¡± nuclear technology. These mud dwellers are, he observed, merely ¡°commentators¡± who do not provide evidence against nuclear power, but rather use myths to ¡°deceive¡± South Africans.

SANEDI on Nuclear for SA
https://www.energize.co.za/article/sa-must-move-forward-nuclear-avoid-dispatchable-power-crisis-sanedi "Titus Mathe said . . . ¡°Other possible options are limited. Battery storage is extremely expensive and the country currently cannot afford to implement this technology at a large scale. Hydropower can take around 15 years to develop . . . " Of course, nuclear can also be very expensive (especially to the taxpayer) and typically takes even longer. "The trading environment favours products from low-carbon economies and Europe is imposing charges based on carbon content,¡± said Eskom Group Executive for Distribution Monde Bala." Indeed! Most important! "Nuclear energy provides a solution that can be retrofitted into existing power plants using modular reactors. ¡°South Africa has been a leading country in modular reactor technology, which is a precursor to small modular reactors that countries such as China are using,¡± said Vikesh Rajpaul, Eskom GM. ¡°This is far safer than water-cooled reactor technology and does not require access to water, which makes it a key tech option for repurposing coal-fired power stations. It can use existing infrastructure, including transmission infrastructure." According to https://en.wikipedia.org/wiki/Small_modular_reactor , "There are more than 80 modular reactor designs under development in 19 countries" (none at present in SA). And the only countries that have commercially operated modular reactors are Russia (a single floating plant with two tiny reactors) and China (pebble bed reactors). And both of these have had abysmal availability factors. Concerning the Chinese HTR-PM, the authoritative 2023 WNISR says, ¡°Between January and December 2022, the reactors operated for only 27 hours out of a possible maximum of 8,760 hours. A mere 0.03% availability factor for the year 2022. In the subsequent three months, they seem to have operated at a load factor of around 10 percent.¡±

Massive Lithium brine discovery in Arkansas
https://www.nytimes.com/2024/10/21/business/energy-environment/arkansas-lithium-ev-batteries.html Arkansas May Have Vast Lithium Reserves, Researchers Say Federal and state researchers said there might be five million to 19 million tons of lithium, more than enough to meet the world¡¯s demand for the battery ingredient. Listen to this article ¡¤ 4:04 min Learn more Share full article Much of the world¡¯s lithium comes from a handful of countries, including Chile where brine containing the metal is placed in huge ponds to dry.Credit...John Moore/Getty Images By Ivan Penn and Rebecca F. Elliott Oct. 21, 2024 Researchers at the United States Geological Survey and the Arkansas government announced on Monday that they had found a trove of lithium, a critical raw material for electric vehicle batteries, in an underground brine reservoir in Arkansas. With the help of water testing and machine learning, the researchers determined that there might be five million to 19 million tons of lithium ¡ª more than enough to meet all of the world¡¯s demand for the metal ¡ª in a geological area known as the Smackover Formation. Several companies, including Exxon Mobil, are developing projects in Arkansas to produce lithium, which is dissolved in underground brine. Whether lithium harvesting takes hold in the region will depend on the ability of those companies to scale up new methods of extracting the valuable battery ingredient from salty water. The processing technique that Exxon and others are pursuing in Arkansas, known as direct lithium extraction, generally costs more than more conventional methods do, according to the consulting firm Wood Mackenzie. Energy and mining companies have long produced oil, gas and other natural resources in the Smackover, which extends from Texas to Florida. And the federal and state researchers said lithium could be extracted from the waste stream of the brines from which companies extracted other forms of energy and elements. Advertisement SKIP ADVERTISEMENT The energy industry, with the Biden administration¡¯s encouragement, has been increasingly working to produce the raw materials needed for the lithium-ion batteries in the United States.

Connect with us on Facebook to get the best of The Times, right in your feed. Most of the world¡¯s lithium is produced in Australia and South America. A large majority of it is then processed in China, which also dominates the manufacturing of electric vehicle batteries. ¡°The potential for increased U.S. production to replace imports has implications for employment, manufacturing and supply chain resilience,¡± David Applegate, the director of the United States Geological Survey, said in a statement announcing the study. ¡°This study illustrates the value of science in addressing economically important issues.¡± Federal researchers also have identified other potential resources that could produce large quantities of lithium, including the Salton Sea in Southern California, where Berkshire Hathaway Energy and other companies are working to extract lithium from hot liquid pumped up from an aquifer more than 4,000 feet below the ground by geothermal power plants. Exxon Mobil recently drilled exploratory wells in Arkansas and was evaluating whether it could extract lithium in a cost-competitive way, Dan Ammann, the president of the company¡¯s Low Carbon Solutions business, said in an interview last month.

We¡¯re working on understanding that cost equation, understanding the supply-and-demand picture,¡± Mr. Ammann said at the time. Exxon said last year that it aimed to enter production in 2027 and to be churning out enough lithium by 2030 to supply more than a million electric vehicles per year.

Future -- Solar Power Generated at Night 4

Not content with building the world¡¯s greatest space-based internet service, Starlink, and also making the world¡¯s only superheavy lift rocket, Starship, they are now offering solar energy from space ¡ª Starpower. ADVERTISEMENT Calling on All Stars! Order Now Unbox finger lickin¡¯ goodness with KFC All Stars ¨C get it via KFC Delivery+ and Uber Eats Inspired by Using Starship¡¯s cavernous cargo bay and robotic space assembly, SpaceX has placed dozens of gigantic mirrors in medium Earth orbit. Rather than trying to harvest solar power in space with panels, and then transmit the power electromagnetically to the ground, Starpower simply focuses the intense sunlight available in space, and reflects it to earthly solar plants ¨C at night! The idea is as genius as it is audacious. But quite compelling. The best solar locations in the world have fewer than 10 cloudy days in a year, but they never generate power at night. Starpower turns an asset that¡¯s idle 65% of the time into a top performer. The return on investment is incredible, despite the hefty fees Starpower charges to ¡°timeshare¡± the Sun. In fact, demand is so great, from California to Namibia to Mongolia, that you have to bid for the most popular hours to have your solar farm irradiated at night. Starpower¡¯s online auction site makes it easy to keep track of your bids and successful trades, just like a stock market app. ¡°It¡¯s the only fair way to sell the sun,¡± says Elon Musk, ¡°and the rates fluctuate according to the weather, season and your specific location. If you¡¯re the only one with clear skies on your longitude, you get a bargain!¡± At this stage it¡¯s only feasible for utility-scale solar installations to benefit from Starpower, as the minimum beam is 4km across, and there¡¯s no compensation for ¡°spillage¡± onto your neighbour¡¯s property, so remote locations are best. And of course there are critics. Environmentalists say ¡°it messes with nature,¡± while astronomers lament more clutter in the night sky.

Hurricanes & Misinformation
https://www.scientificamerican.com/article/why-disasters-like-hurricanes-milton-and-helene-unleash-so-much/ Meteorologists and FEMA employees have even received death threats. Why Disasters Like Hurricanes Milton and Helene Unleash So Much Misinformation Falsehoods spread when uncertainties¡ªand emotions¡ªare high after hurricanes By Ben Guarino Members of the FEMA Urban Search and Rescue Task Force search a damaged area in the aftermath of Hurricane Helene along the Swannanoa River on October 4, 2024 in Asheville, North Carolina. FEMA has been the subject of a barrage of misinformation in the storm's wake. Mario Tama/Getty Images Psychology While Florida recovers from Hurricane Milton, the second dangerous storm to hit the U.S. Southeast in just a couple of weeks, a flood of misinformation threatens to compound the disasters. A major target of false claims is the Federal Emergency Management Agency (FEMA), the government body coordinating recovery efforts from Hurricanes Milton and Helene¡ªthe latter of which has killed at least 230 people since the storm made landfall in late September. FEMA has set up a debunking page because it faces so many harmful and inaccurate rumors. And in a telling example of how far things have gone, Representative Chuck Edwards of North Carolina, a Republican, had to dispel lies in a letter to his constituents this week: ¡°Hurricane Helene was NOT geoengineered by the government to seize and access lithium deposits in Chimney Rock,¡± he wrote. FEMA is not seizing anyone¡¯s property. The agency did not prevent evacuations. Its grant programs generally don¡¯t require repayment. FEMA¡¯s disaster relief funds were not diverted to assist migrants at U.S. borders. Chimney Rock doesn¡¯t have any lithium mines. Uncle Sam can¡¯t control storms. But conspiracy theories making such claims have spread swiftly¡ªand with startling prominence. ¡°What we¡¯re seeing now is pretty unprecedented,¡± says Lisa Kaplan, chief executive of Alethea, a cybersecurity company that tracks the spread of false narratives online. Former president Donald Trump, tech tycoon Elon Musk and Representative Marjorie Taylor Greene of Georgia all have promoted lies or false theories about the hurricanes or disaster responses. ¡°You always see misinformation after disasters,¡± says Lisa Fazio, an associate professor of psychology at Vanderbilt University. ¡°You don¡¯t always see national political figures being the ones spreading that misinformation.¡± Trump has repeated a torrent of baseless stories at rallies and on his social media platform, Truth Social. He has claimed, for instance, that the federal government has gone out of its way ¡°to not help people in Republican areas¡± and that FEMA had no responders in North Carolina. FEMA administrator Deanne Criswell told CNN on Tuesday that Trump¡¯s ¡°accusations are just completely false,¡± pointing out there are some 3,400 workers from multiple federal agencies assisting with the state¡¯s disaster response. ¡°We have just got to stop this rhetoric,¡± Criswell said. She said she worried that people wouldn¡¯t register with FEMA to get the help¡ªincluding money¡ªthat is readily available to them. Misinformation that foments distrust can endanger responders, too, or at least make their job more difficult as they seek to keep people safe in the aftermath of deadly storms. Why target FEMA? Conspiracy theories about FEMA are about as old as the agency itself, which was founded in 1979. One early piece of misinformation from the 1980s claimed that FEMA would round up American patriots and place them in ¡°detention camps¡± run by the agency. (The 1998 X-Files movie lampooned these fears, with Martin Landau¡¯s character warning that FEMA had covered up an alien virus and was about to establish a totalitarian government.) Craig Fugate, the agency¡¯s administrator from 2009 to 2017, says that false rumors about FEMA are ¡°not readily new¡± but ¡°social media spreads them faster.¡± During his tenure, FEMA had to debunk rumors about 2012¡¯s Superstorm Sandy¡ªincluding fake reports that the agency was hiring people to clean up debris i

?? Three Mile Island and AI
---------- Forwarded message --------- From: The Spark from MIT Technology Review <newsletters@...> Date: Wed, 25 Sept 2024, 18:04 Subject: ?? Three Mile Island and AI To: <pwvanderwalt@...> Why Microsoft is looking for nuclear power Subscribe & Save 25% The Spark By Casey Crownhart ? 9.25.24 Hello hello, welcome back to The Spark! Nuclear power is coming back to Three Mile Island. That nuclear power plant is typically associated with a very specific event. One of its reactors, Unit 2, suffered a partial meltdown in 1979 in what remains the most significant nuclear accident in US history. It has been shuttered ever since. But the site, in Pennsylvania, is also home to another reactor¡ªUnit 1, which consistently and safely generated electricity for decades until it was shut down in 2019. The site¡¯s owner announced last week that it has plans to reopen the plant and signed a deal with Microsoft. The company will purchase the plant¡¯s entire electric generating capacity over the next 20 years. This news is fascinating for so many reasons. Obviously this site holds a certain significance in the history of nuclear power in the US. There¡¯s a possibility this would be one of the first reactors in the country to reopen after shutting down. And Microsoft will be buying all the electricity from the reactor. Let¡¯s dig into what this says about the future of the nuclear industry and Big Tech¡¯s power demand. Unit 2 at Three Mile Island operated for just a few months before the accident, in March 1979. At the time, Unit 1 was down for refueling. That reactor started back up, to some controversy, in the mid-1980s and produced enough electricity for hundreds of thousands of homes in the area for more than 30 years. Eventually, though, the plant faced economic struggles. Even though it was operating at relatively high efficiency and with low costs, it was driven out of business by record low prices for natural gas and the introduction of relatively cheap, subsidized renewable energy to the grid, says Patrick White, research director of the Nuclear Innovation Alliance, a nonprofit think tank. That situation has shifted in just the past few years, White says. There¡¯s more money available now for nuclear, including new technology-agnostic tax credits in the Inflation Reduction Act. And there¡¯s also rising concern about the increased energy demand on the power grid, in part from tech giants looking to power data centers like those needed to run AI. In announcing its deal with Microsoft, Constellation Energy, the owner of Three Mile Island Unit 1, also shared that the plant is getting a rebrand¡ªthe site will be renamed the Crane Clean Energy Center. (Not sure if that one¡¯s going to stick.) The confluence of the particular location of this reactor and the fact that the electricity will go to power data centers (and other infrastructure) makes this whole announcement instantly attention-grabbing. As one headline put it, ¡°Microsoft AI Needs So Much Power It's Tapping Site of US Nuclear Meltdown.¡± For some people in climate circles, this deal makes a lot of sense. Nuclear power remains one of the most expensive forms of electricity today. But experts say it could play a crucial role on the grid, since the plants typically put out a consistent amount of electricity¡ªit¡¯s often referred to as ¡°firm power,¡± in contrast with renewables like wind and solar that are intermittently available. Without guaranteed money there¡¯s a chance this reactor would simply have been decommissioned as planned. Reopening plants that shuttered recently could provide an opportunity to get the benefits of nuclear power without having to build an entirely new project. In March, the Palisades Nuclear Plant in Michigan got a loan guarantee from the US Department of Energy¡¯s Loan Programs Office to the tune of over $1.5 billion to help restart. Palisades shut down in 2022, and the site¡¯s owner says it hopes to get it back online by late 2025. It will be the first shuttered reactor in the US to come back online, if everything goes as planned. (For more details, check out my story

Die diagram by 2:30 van fusie is totaal foutief: die energie daaruit is kineties, en selfs 'n matrikulant kan maklik bewys dat die heliumkern (alfa-partikel) met massa 4 a m e slegs 20% van die energie dra, en die neutron (1 a m e) 80% oftewel 14.3MeV.
