waste

the great waste management fraud

by

In the early 1980s, some North American cities began to realize that the waste generated by plastic was enormous and uncontrollable. Technicians and activists began to talk about regulations and prohibitions, but the industry found another way to solve it: recycling. The standard. For 50 years, the petrochemical industry has promoted recycling as the ‘gold standard’ for solving plastic pollution. Today, We know that only 9% of all plastic produced historically has been recycled. It was not a miscalculationnor a display of naive optimism: it was a large-scale industrial fraud. A documented fraud. In 1973, ahead of the regulatory wave, the Society of the Plastics Industry commissioned a report to see what could be done with the plastic they made themselves. The study’s conclusions were devastating: not only did it recognize the inherent degradation of resins in each reprocessing cycle, but it made clear that (even in the best of cases) there was no market for the final product. And, of course, the industry didn’t care. A report from the Center for Climate Integrity and the summary of a macro-case by the California attorney general against ExxonMobil give us the keys to understand it. Because it’s not exactly a secret. An Exxon employee recognized in 1994 before the American Plastics Council that “the company was committed to recycling activities, but not to their results.” The founder of the Vinyl Institute (one of the sector’s lobbies) admitted in 1989 that recycling could not be continued indefinitely and that, of course, it did not solve the problem of solid waste. We have proof. What’s more, for decades, we have known that there are internal documents that show patterns of investments in recycling plants that were closed or abandoned once they had fulfilled their public relations function. The tests go on and on. However, no one paid much attention. The parallelism with climate denialism ands patent: the documentation is crystal clear. The industry knew recycling wouldn’t work, but spent millions and millions actively promoting it with the idea of ​​avoiding regulations. And why is it news now? Because there are doubts that this is over. Yes, the average citizen has internalized that separating waste and depositing it in the yellow container (or the equivalent system) is an effective environmental action. In fact, the better the citizen recycles, the more effective the industry’s alibi is to continue producing plastic without restrictions. Recycling actually displaces regulatory pressure. Because the data (and recycling rates whatever the approach) is not as good as we might think. And the problem is volume. Plastic production is going at such a speed that even by significantly improving recycling rates we would not be able to reduce the amount of plastic that ends up in the environment. And what do we do? That’s the big question: what do we do. Our society has become so dependent on plastic that the most effective solutions are outside the realm of possibility. But if the situation continues like thisthey will stop being so sooner rather than later. Image | Nick Fewings In Xataka | We have known for years that our recycling system is broken.

The big problem with nuclear energy has always been its waste. Russia can now recycle them up to five times

by

A nuclear reactor operating for 60 years using a closed system of three circulating fuel loads, subjected to cleaning processes and specific recharges in each cycle. What until recently seemed like an unattainable technical utopia for the energy industry is the reality that Russia’s latest technological breakthrough points to. The historic Achilles heel of nuclear fission—radioactive waste—is about to take a radical turn to become an almost inexhaustible resource. The magnitude of the test. The press release of Atom Media explains that Unit 1 of the Balakovo nuclear power plant (operated by Rosatom’s energy division) has just made history. They have successfully removed the last three lead test assemblies from an innovative fuel dubbed REMIX. These groups have completed three operating cycles of 18 months each. We are talking about 54 months performing at maximum capacity in a Russian commercial reactor type VVER-1000, thus exhausting its standard useful life. This puts the finishing touch to a demanding pilot program which started at the end of 2021 when the first six experimental rods were introduced into the reactor core. The resounding success. The most impressive thing about this milestone is not just that the fuel works, but where it works. Unlike other experiments designed for new generation fast reactors, REMIX fuel can be used in light water thermal reactors already operating massively around the planet. And without the need to modify its design or add costly security measures. The rehearsal went flawlessly. Yuri Ryzhkov, deputy chief engineer of the Balakovo power plant, detailed: “After each cycle, the fuel rods and structural elements were inspected using the television camera of the refueling machine. No deviations were detected during operation; neutron, physical and service characteristics remained within the design limits.” The science behind REMIX. But what exactly is this material? REMIX comes from Regenerated Mixture (Regenerated Mixture). Instead of using the usual natural enriched uranium, Russian scientists have created a matrix pellet that mixes regenerated uranium and plutonium (both recovered from already spent and reprocessed nuclear fuel), seasoned with some fresh enriched uranium. The technical key to the process is in the proportion: it maintains a very low level of plutonium, up to 1.5%. Thanks to this exact formulation, its neutron spectrum is practically identical to that of standard fuel. For practical purposes, the reactor core behaves the same and does not even “notice” the difference. The cleaning process. It is the circular economy taken to the atomic extreme. The magazine World Nuclear Newyes explains that this recycling cycle can be repeated up to five times. With each pass, the industry reprocesses the material to separate the useful uranium and plutonium from the fission products, which constitute the true radioactive waste. This useless waste is extracted and vitrified (encapsulated in glass) to be permanently and safely buried in geological deposits, while the useful fuel mixture is reintroduced into the reactor. The vision of the balanced cycle. Now it’s time for the laboratory and certification phase, where the irradiated material, now resting in cooling pools, will travel to the Atomic Reactor Research Institute in Dimitrovgrad for exhaustive analysis. Alexander Ugryumov, Vice President of R&D at TVEL (Rosatom’s fuel subsidiary), He announced that after these studies They will be able to bring the product to the market. The next evolutionary step will be to test mixtures with depleted uranium and up to 5% plutonium. All this is part of what Rosatom has called the “Balanced Nuclear Fuel Cycle” (NFC). The goal is to drastically reduce the volume and danger of radioactive waste, solving the historic problem of long-term storage for future generations and guaranteeing a truly sustainable production system. An impact on a global scale. Although the technical success is undeniable and the operational milestone in a commercial reactor is demonstrated, the mass adoption of this technology on a global level will largely depend on the commercialization costs and the economic viability of large-scale reprocessing; factors that the industry must demonstrate after the current qualification phase. However, if Rosatom manages to market REMIX at competitive prices, the global energy situation could take an unprecedented turn. We are not talking about a niche experiment. The data provided by Atom Media illustrate this magnitude: TVEL currently supplies fuel to more than 70 power reactors in 15 countries. Today, one in six reactors in the world operates with its technology. Moving from a linear “use and bury” industry to a closed loop where nuclear resources have multiple lives would not only dramatically expand the planet’s energy reserves, but could forever redefine the ecological viability of nuclear energy.

Nuclear waste is a problem, so Germany is looking for the solution in a Jurassic rock in Switzerland

by

Nuclear energy is capable of generating clean electricity, continuously and in large quantities. A marvel except for two small details: the risk of a possible leak and what to do with its waste. The most widespread solution is bury them in a nuclear cemetery and wait. How much? Well, it depends, but it could be hundreds of thousands of years, until they are no longer dangerous. The million dollar question is where. An international research team led by Germany has started to drill a hole in a Swiss mountain to try to answer it. The project. Her name is DEBORAH (Deep borehole to resolve the Mont Terri Anticline Hydrogeology), stands for deep drilling to understand the hydrogeology of the Mont Terri anticline and is exactly what it does. Your goal? Document in great detail the layers that exist and their properties. There is some especially interesting material: Opalinus Clay. This deep experiment involves the German Geosciences Research Center GFZ and the German Federal Institute for Geosciences and Natural Resources (BGR), the Nuclear Waste Service (NWS) of the United Kingdom and Swiss researchers from the University of Bern. Why is it important. Because it can be the ideal rock to build a radioactive waste deposit. As details GFZSwitzerland has already made the decision, but Germany and the United Kingdom (the other parties to the project) have not yet. The key is what the analysis of the drilling says: details such as how much water it allows to filter, at what speed or where it will be key to making the decision. It is not trivial: a leak, no matter how slow and small, can contaminate aquifers. What’s special about it. The Opalinus is a clay rock dating back to the Middle Jurassic, with an estimated age of approximately 175 million years. Simply put, it is clay that has been compacted into rock. And it has a property that makes it a good candidate for nuclear storage: its very low permeability. Context. The study of Opalinus is not new by any means: GFZ’s on your radar for 30 years because, in addition to its very low permeability, it has properties such as its plasticity (under pressure, warps instead of breakingsomething convenient if it works as a radioactive deposit) or its ability to retain certain radionuclides. Switzerland has already chosen it, but it remains to be known how it behaves under the conditions that exist in much deeper areas, where, for example, temperature or pressure change noticeably. How they do it. In the Swiss canton of Jura, near the municipality of Saint-Ursanne, there is that Mont Terri. In its bowels there is an underground laboratory that is accessed through the security gallery of a highway tunnel, about 150 – 200 meters underground. A drilling platform works continuously there, advancing meter by meter, until reaching a depth of 800 meters. The drill uses a hollow crown that allows extracting intact rock columns, the sample that is later analyzed in the laboratory. Each advance works as a witness insofar as it reveals the age, the composition, the fractures and the differential quality: how it behaves with water. In addition, they use seismic and gravimetry techniques to obtain a complete x-ray of what is hundreds of meters deep. In Xataka | Ships have been damaging the oceans with noise for centuries.

The “bottom of the barrel” was the cheapest waste of the oil industry. The war in Iran has just turned it into an unaffordable luxury

by

Historically, the fuel oil has been known in the oil industry as the “bottom of the barrel.” Typically cheap and underappreciated, this byproduct comes from the bottom of distillation towers, the equipment where crude oil is heated and split into multiple products. In fact, very often, this fuel cost less than a barrel of crude oil, and refineries sold it at a loss as it was a simple remnant of the process necessary to manufacture high-value products such as diesel. However, as expert Javier Blas warns in your column for Bloombergthe Iran war has turned the industry upside down. That waste that no one wanted has become an ultra-expensive raw material overnight, which is bad news for the global economy. Despite being overshadowed by other distillates, the fuel oil plays an immense role in the modern world, driving container ships that act as the workhorses of globalization. The breakup of a market at the limit. In the current conflict, all eyes they are set in the rises and falls of crude oil. However, the real drama is hidden in the physical maritime bunker markets, where the traditional relationship between the price of crude oil and refined products has been completely broken. With crude oil hovering around $100, the fuel oil It shouldn’t be much more expensive. In reality, it is trading at $140 a barrel in Singapore and almost $160 in the Emirati port of Fujairah. A report of Lloyd’s List explains that the average price of the fuel oil of very low sulfur content (VLSFO) in the 20 main bunkering centers reached $1,005 per ton, double its pre-war cost and the highest figure since the Russian invasion of Ukraine. For his part, analyst Clyde Russell warns in his column Reuters that, while crude oil futures are confident of a solution, prices for physical cargoes are sending signals of an impending crisis and a supply chain that is buckling under pressure. The missing link. The key to this specific crisis lies in geography and geology. As Blas points outrefineries in Saudi Arabia, Kuwait and the United Arab Emirates produce 20% of all fuel oil sold internationally. Added to this is a crucial geological factor: the crude oil from the Persian Gulf generates much more fuel oil than that of other regions. For example, when distilling a barrel of Saudi flagship crude oil (Arab Light), approximately 50% of what comes out is residue for fuel oil, compared to 33% left by US WTI crude oil. This explains why the blockade of the Strait of Hormuz is a death trap specifically for this byproduct. The logistical panic. The real urgency is no longer just the price, but physical availability. The shipping industry has raised the alarm because supplies are critically low in Singapore and Fujairah, two of the world’s most important bunkering hubs. “If we do nothing, we risk ending up with dry supply points in Asia,” Vincent Clerc sharply warnedCEO of shipping giant Maersk. To avoid collapse, Maersk needs to be proactive and is transporting its own fuel around the globe to have the right amount in the right place, an unprecedented challenge that Clerc compares to the logistical juggle experienced during the Covid-19 pandemic. On a day-to-day basis, the charter market is paralyzed. Scott Bergeron, CEO of Oldendorff Carriers, confess to Lloyd’s List that there are problems getting fuel quotes, and that “availability for April is a big question mark.” The operational consequences will be drastic: Global slowing: Ships will reduce their speed to conserve fuel. Port congestion: Massive congestion is expected in ports that still have reserves. Accelerated scrapping: Older and inefficient fleets could be forced to be scrapped due to the enormous costs. Furthermore, according to Clyde Russell in your column for ReutersAsian refiners are cutting production, and countries like South Korea could restrict exports, pushing dependent nations like New Zealand into rationing measures. The environmental dilemma. This severe lack of supply is even putting pressure on climate regulations. Given the suffocating lack of distillates, The Maritime Executive details that the regulators could be tempted to temporarily suspend IMO 2020 emissions regulations. This would allow ships to return to burning heavy fuel oil (HSFO) widely, freeing up ingredients for other critical sectors. Meanwhile, ships already equipped with scrubbers (scrubbers) can still legally burn the cheaper HSFO. As the price gap between clean and dirty fuel widens, these shipowners are realizing massive savings; In fact, this price spread reached $189.50 per ton in Singapore. The current crisis leaves no room for maneuver. As Javier Blas saysthe world has already spent its main lines of defense against this oil shock: compromised refineries have been avoided and strategic reserves have been emptied. Looking to the future, the only variable capable of balancing consumption with a meager supply is the “destruction of demand” through suffocating prices. Ship fuel may come from the bottom of the barrel, but it has proven to have the ability to sink or keep afloat international commerce. Today, without a doubt, it has become the world’s main problem.

the first large pure hydrogen turbine to fight renewable waste

by

Talking about renewable energies is talking about China. Although they continue to burn coal and gas and want to become an oil power, the country is positioning itself as the major player in renewables. Also of the ‘megastructures’. And, combining both, we have Jupiter I. It is the first 30 MW class turbine in the world that works with pure hydrogen, it has just been launched. light and they aspire for it to be the solution to one of the biggest renewable energy problems. Take advantage of surplus energy. Jupiter I. Like practically everything that has to do with energy and China, the numbers of this plant are, to say the least, striking. Now we will get into the fact that it is the first 30 MW class turbine that runs on pure hydrogen. There are others in the world that operate in pilot mode on a scale of 5 or 10 MW, but they are natural gas turbines that have been converted. Jupiter I has been designed from the ground up as a pure hydrogen machine that, in combined cycle mode, can generate 48 MWh. It is estimated that it is enough to satisfy the daily demand of more than 5,500 homes. Those responsible for the turbine they claim that the machine “can use more than 30,000 m³ of hydrogen per hour, which calculated annually is the equivalent of 500 million kWh.” In perspectiveit’s like filling the gigantic Hindenburg airship 25 times every hour. And the key to this is that it is electricity stored in the form of hydrogen pure hydrogen. Although it has not fully caught on in sectors such as utility vehicles, hydrogen has the potential to be one of the fuels that helps achieve decarbonization objectives. It all depends on its color: green is achieved through renewable energy and black through burning coal, for example. Turbines are classified according to the type of fuel they burn and the percentage of hydrogen in the mixture. There are those that use only up to 20% H2, others that use 50% H2 and those that use pure hydrogen, which operate entirely with this fuel. They are usually pilot or demonstration units, but Jupiter 1 is the first of its kind in which all its systems (combustion chamber, injection and flame control) are optimized for that fuel. Megaplant. The turbine is not isolated. It is located in Ordos, Inner Mongolia, and is part of a larger system. It is inside a 500 MW wind farm. It is not an astronomical figure considering what we are used to, but it is important to remember that not all the energy produced by renewables is stored correctly. Much of it is wasted, either because there are not enough batteries, or because it is not consumed when needed or because it is stored and lost. How it works. That’s where Jupiter I comes into play. The system works through a kind of closed cycle of electricity – hydrogen – electricity. When wind turbines generate more energy than the grid can consume and it is not going to be stored in batteries, turbines like this one can use that excess to produce green hydrogen. Once produced, it is stored in tanks, and at the Ordos plant there are a dozen of 1,875 m3 each. If the grid is stable and can operate well with renewables, that hydrogen is stored there, but in times of greater demand or when renewables cannot satisfy it, that stored green hydrogen comes into play to produce emissions-free and immediately accessible electricity. Fighting deserts. Placing a hydrogen turbine right in a renewable plant solves the challenge of wasting electricity, but also that of transporting hydrogen, which we have already seen is complicated. Precisely, that is where those responsible say that the technology has great potential. It is in the deserts where China has found an oasis of renewable energy, and having turbines of this style can further enhance those megascale energy projects – greater than 1 GW – that China is deploying. Now we have to see if it fulfills what it promises, since it is the first of a pilot project, but according to warned by the China National Energy Administration in June this year, it will not be the last.

Working in a nuclear power plant is not the best way to avoid cancer. Now it turns out that its waste also serves to cure it

by

If there is a terrifying and mainstream disease, it is cancer: after all, according to the WHOone in five people will develop it at some point in their life. Although in some cases the risk factors vary depending on the type of cancer, working in a nuclear power plant poses some riskas long as there is greater exposure to ionizing radiation, even if there are no accidents or more intense exposure through maintenance work. Paradoxically, the activity of nuclear power plants, which can cause cancer, also serves to generate the basis of the medicine to cure it. And we are not talking about a potentially distant study, but rather something that can already be materialized. In fact, the United Kingdom has already taken a step forward to transform some of its radioactive waste into anti-cancer medication. The world’s first lead-212 radiopharmaceutical ecosystem. Because in the UK they have closed an agreement between the public body Nuclear Decommissioning Authority and the biotechnology company Bicycle Therapeutics for which the latter will have 400 tons of reprocessed uranium to extract the valuable (for the medical industry) lead – 212 for 15 years. Behind Bicycle is Sir Greg Winter, co-founder of the company and winner of the Nobel Prize in Chemistry in 2018. This will provide them with the infrastructure to create the world’s first end-to-end lead-212 radiopharmaceutical ecosystem, from discovery to commercial supply. So explains it Mike Hannay, Chief Product and Supply Chain Officer at Bicycle Therapeutics. The benefits of lead – 212. Lead – 212 is an isotope used in therapeutic contexts thanks to its particular decay properties, so that it emits both alpha and beta particles. While the former provide high-energy, short-range cytotoxicity, the latter have a more extended range, targeting micro-metastasis. In a simplified way, this medically applicable isotope is essential for precision treatments against tumors resistant to other therapies. Thus, it carries radiation and acts directly on cancer cells to destroy tumors, minimizing the damage to the surrounding healthy tissue. This type of technique offers promising results in prostate cancers and neuroendocrine tumors of organs such as the intestine or pancreas. Extracting lead-212 is an arduous task. Converting the waste from nuclear power plants into cancer treatments seems like a fantastic idea for two reasons: because of the cure for cancer itself and the problem of dealing with radioactive waste, one of the great challenges faced by these energy industries, which have also explored other avenues such as take advantage of the remaining energy. But getting here has not been easy: the extraction process of this isotope has been carried out by the United Kingdom National Nuclear Laboratory (UKNNL) with a complex chemical process that requires the isolation of scandalously small quantities of the precursor material from the used nuclear fuel. Thus, first the Thorium-228 is extracted from the reprocessed uranium to later process it into Radium-224. It is then loaded into a lead-212 generator that has been custom-made for Bicycle Therapeutics’ needs by US company SpectronRx. This is a continuous regeneration, producing enough lead-212 to deliver tens of thousands of doses of precision therapy per year. The laboratory explains that the critical part is in the beginning: “The initial precursor material extracted is comparable to finding a single drop of water in an Olympic swimming pool.” From that minute amount, an even smaller fraction of lead-212 is separated. First discover the universe, then cure cancer. In addition to this unexpected use of nuclear power plant waste, in recent weeks a group of researchers from the University of York have evidenced in a study that the intense radiation captured in the beam absorbers of particle accelerators could be reused to produce materials used in cancer therapies. Those particle accelerators They are used, among other things, in experiments to discover the matter of which the universe is composed. In Xataka | The rarest element on Earth aims to cure cancer.

Mining waste is changing life in the depths of the Pacific

by

More than a thousand meters below the Pacific, a turbid cloud slowly disperses. It is not pollution visible from the surface, but it could transform the ocean from its foundations. That cloud—a mix of sediment, metals, and mining waste—is the byproduct of a new global fever: the race for minerals from the seabed. A recent study published in Nature warns of a little-known risk. By extracting metals from the seabed, underwater mining releases a cloud of waste as fine as dust. This material can replace the food that millions of small organisms need to survive. They are tiny, almost invisible creatures, but without them there would be no fish, whales or marine life as we know it. A deep problem. A team from the University of Hawaii at Mānoa analyzed for the first time the effects of a test spill made during a mining operation in the Pacific. Researchers discovered that the waste generated by extracting polymetallic nodules – potato-sized rocks packed with valuable metals such as nickel, cobalt or manganese – can drown the so-called “twilight ocean”, an area that extends between 200 and 1,500 meters deep. The results are overwhelming: the particles from the mining process are between 10 and 100 times less nutritious than natural particles. “It’s like replacing food with air,” explains Michael Dowdlead author of the study. Their work shows that this waste can displace organic particles that feed zooplankton and other species that, in turn, support fish, whales and tuna. The study, carried out in the Clarion-Clipperton Zone – a vast region of the Pacific of 1.5 million square kilometers under license from the International Seabed Authority (ISA) – calculated that 65% of the species analyzed depend on particles larger than six microns, exactly those that would be replaced by mining waste. More than half of the zooplankton and 60% of the micronekton feed on them. The journey of waste. During the process, underwater mining generates a flow of water, sediment and metals that is pumped to a ship on the surface. There the valuable minerals are separated and the rest of the material – a mixture of mud and inorganic fragments – is returned to the sea. The problem is where it is returned. Some companies, such as The Metals Company (TMC), have proposed release the residue in the so-called “mesopelagic zone”, an area rich in microscopic life. According to scientists, this could cause a “cascade effect”: organisms that filter particles to feed would run out of nutrients, and the predators that depend on them—from fish to cetaceans—could migrate or starve. That is why the authors recommend that, if companies insist on mining, they at least return the sediments to the seabed, where they were extracted, even if that is more expensive and technically complex. However, from the company, which financed the study but did not intervene in its conclusions, he assured The Verge which plans to release the waste at a depth of about 2,000 meters, below the area analyzed by the researchers. According to its environmental director, Michael Clarke, the particles dissipate quickly and there is less planktonic life at those depths. The rules of the fund: the battle in the ISA. The rules of the seabed are still being written in slow motion. Regulation falls to the International Seabed Authority (ISA), the UN body in charge of managing mineral resources in international waters. Since 2014, the ISA has been working on a Mining Code that has not yet been approved. For now, it has only granted exploration licenses, but none for commercial exploitation. Meanwhile, some countries are pushing to move forward without waiting for the final code. In fact, Donald Trump has tried to bypass the international process signing an executive order that allowed US companies to be granted permits to mine the seabed. The measure has been seen by ISA Secretary General Leticia Carvalho as a “dangerous precedent that could destabilize ocean governance.” A geopolitical board in dispute. American interest is framed in the technological and trade war with China. The Asian giant controls about 70% of the global rare earth market and has multiple exploration contracts in the Clarion-Clipperton Zone. Faced with this dependence, the White House seeks to guarantee its own supply of strategic metals by promoting deep-sea mining and creating national reserves, but the country has not ratified the United Nations Convention on the Law of the Sea (UNCLOS). In other words, the United States not part of the ISA. Meanwhile, countries such as Norway, Japan, Papua New Guinea and China are moving forward with their projects. At the last ISA meeting, 32 nations—including Spain—requested a global moratorium to curb underwater mining until its impacts are better understood. Between two waters. The fate of the seabed is written at the same time in the laboratories and in the negotiation rooms, far from the blue silence thatwe still don’t fully understand. The little we know is that beneath that darkness await the metals of the future and perhaps also the price of extracting them.

Emptied Spain has been filled with solar mills and panels, but waste energy for a simple reason: there are no cables

by

At noon, the sun and the wind are left over in the emptied regions. At dusk, the cities turn on the gas. Spain has run more than anyone raising renewables in the unpopulated territory, but the cables that take them to the demand are not tended at the same speed. The result is a broken bridge: clean energy is born in emptied Spain and does not arrive, when it is necessary, urban Spain. Today, for the first time, the distributors have published the “Map of Plug” for new demand: the photo is stark. The expected map. By mandate of the National Commission of Markets and Competition (CNMC), the great distributors —I-de (Iberdrola), e-Distribution (Endesa), UFD (Naturgy), E-Redes (EDP) and Repsol Distribution— They have published the capacity maps To connect new firm demand to the distribution network. It is an radiography where they show, knot to knot, where there is a hole, what is busy and what is in process. According to the employer Aelēcthe first results confirm that 83.4% of knots are already saturated, which prevents connecting new consumptions such as industries, data centers, storage or electric vehicle recharge. The association itself defines it as “transparency milestone”, but warns that, under these conditions, without investment, the transition is raised. The great territorial neck. Here is the core of the problem. Spain has installed renewables where there is resource and soil: rural regions with low density and little network. However, demand grows in cities: metropolitan areas, logistics corridors, data clusters. In the middle there is an electrical system that does not endure that mismatch, since transport corridors are missing to evacuate surpluses and, above all, distribution capacity to connect the new demand where it is requested. The result is that at noon there are many cheap MWh that are cut or sold at zero price; When the sun falls, the network needs support and the gas enters, Based on pool. The double face of emptied Spain. If the anticipatory network is not remunerated and planned, there will be no industries, CPDs, or recharge of electric vehicles, or hydrogen or storage projects that create employment and set population. But if investigated without criteria, the cost will fall on rates without effective use. The key is agile planning, clear priorities and mechanisms that accelerate reinforcements where demand is plausible: poles such as Aragon, but also Extremadura, Castilla y León, Castilla-La Mancha or inner Andalusia, where hot knots and curtailment-up to 30% renewable wasted by saturation– They are already common. The demand boom. There is a very illustrative fact: The increase in data centers. Applications to get an access point have multiplied by 80 compared to previous years, According to the Spanish. Among them are technological, great consumers and promoters of hybrids that seek to consume in situ. Aragon has become an epicenter. Only the projected data centers would add more than 2 GW of requested power, with Amazon Web Services, Microsoft or QTS/Blackstone at the head. In this new scenario, the race for a “plug” is no longer limited to first: weigh guarantees, guarantees and project criteria. “Historic traffic jam.” The “complete maps” – without significant hollows – stress even more the pulse with the CNMC. The fear of the sector is double: losing industrial and digital projects (including CPDs) for not being able to connect them and see investment relocation if the jam persists. The electricity story connects that urgency with the regulated remuneration: they argue that with a rate of 6.46% the volume of reinforcements required by the demand wave required, and remember that in other countries (Italy, United Kingdom, Sweden) the reference rates are higher; In Spain, they ask around 7.5%. For its part, the CNMC two proposals presented in July: a financial compensation rate of 6.46% by 2026-2031 (from current 5.58%) and a new distribution methodology that turns towards the Totex model (CAPEX + OPEX). This system includes incentives for efficiency and quality, and league part of the remuneration to the contracted power, to avoid overrredes that end up paying consumers. The regulator insists that the framework must encourage investment without compromising the affordability of the invoice. The forecasts. Access to the distribution network no longer depends only on the order of arrival. The processing requires guarantees, technical draft and guarantees, and a period of one month to present the documentation after reserving a point. The resolutions should be issued in less than six months, with technical support for Red Electric. In addition, scores that value CO₂, investment volume and speed at the beginning of consumption are applied. In parallel, solutions such as battery PPAS arise, which allow to finance storage and take advantage of the cheap electricity at noon at the afternoon, avoiding the resource to gas. But without broader investment limits, as Aelēc claimsthe bridge between rural Spain and urban Spain will remain broken. The PNIEC foresees more than 53,000 million in networks until 2030, although the CNMC defends to maintain the rate at 6.46% for efficiency and affordability, while the sector asks for greater certainty and return. The political context adds pressure: after the rejection of the “Decree antiaps” In July, the dilemma is sharpened. The end point. Spain does not have a sun or wind problem; It has a bridge problem between where it occurs and where it is consumed. Capacity maps have made what the industry had been suffering: the distribution network is at the limit. Without a jump in investment and planning, the transition will be stuck where there are less labor and more territory. If the network does not reach empty Spain, clean energy will not reach rich Spain. The choice is not whether to invest or not, but how, where and with what rules so that the cost does not pay it neither the countryside nor the city, but the economic future of both.

If you are even the noses of the velutinasthe Backpacks and the Tigres mosquitoes and Japanesethink about this: there are people in South Carolina (USA) that what fears right now is the stalking of radioactive wasps. It sounds crazy, but it makes all the meaning of the world if one takes into account that there, near a plant in which in its day pieces for nuclear bombs were manufactured, They just found A loop with a radiation level ten times above what is allowed. The big question is … how is it possible? What happened? That a few days ago the US Department of Energy published A report which has generated Polvareda in the country’s media. And rightly. The document does not go demand and supply, renewable or prices, but of something much more picturesque: earlier than the month, on Thursday 3 to be precise, some operators located near Aikenin South Carolina, a wasps nest with a radiation level ten times higher to what federal regulations allow. The authorities insist In any case where there is no risk. Where did they find it? Near a radioactive waste tank Savannah River Sitea nuclear material processing center located in South Carolina, next to the Savannah River, and that rose to mid -last century to refine useful materials for weapons creation. The NBC chain states that in its day, at the beginning of the cold war, it was used to manufacture the plutonium nuclei necessary to mount nuclear pumps. Now the installation is dedicated to other works, such as fuel production for nuclear centrals and cleaning tasks, but some sources They point that has generated More than 625 million Of liters of nuclear waste, an amount more than considerable that, once processed, it stayed at around 129 million. 43 underground tanks remain in use. OTHER EIGHT ARE CLOSED. What did they do with the nest? They sprayed him with insecticide, they removed him and discarded him as a radioactive residue. Finally the team prepared A reporta document that took more than expected because its authors dedicated themselves to review Previous cases of fauna pollution to be sure of your criteria. The document concludes that “more actions on the land” are necessary. Is anything else known? Yes. To begin with that they only found the loop, No wasps. Aiken Standard Clarify In any case that if insects had been located, they would probably present quite lower pollution levels. The same newspaper indicates that, after detecting the nest, the radiological control operating staff (RCO) inspected the surroundings without identifying more pollution or threats to the workers. The area in which the nest appeared is inside the plant, where underground steel tanks and several meters deep are preserved. The CNN chain collect Savannah River Mission Completion statements that rule out that there is a risk that the wasps created by the loop can fly outside their facilities. The reason: the normal thing is that they do not move too far from their nests. How is it possible? That is the million dollar question. The report speaks of “inherited radioactive pollution” and “not related to a loss of control”. The event would therefore be explained by the residual radioactivity That remained when the center was fully operational, not for possible leaks. The text in any case does not seem to have satisfied the Savannah River Site Watch surveillance team, which considers that it is incomplete because it does not detail where pollution came from or how exactly came to insects. “I am furious because SRS did not explain where radioactive waste comes from or if there is any type of escape in the tanks that the public must know,” Recognize Tom Clementsgroup manager. One of the keys would be the type of nest, since not all wasps use the same materials to create their homes.

A deep warehouse that will save waste until 2100

by

A few weeks ago, more than 1,800 nuclear waste drivers They began to emerge of the seabed on the Galician coast. The image, as real as symbolic, reopened an old debate: what do we do with the remains of an era that goes out, but does not disappear? While Galicia demands answers and surveillance, another nuclear issue advances without noise, although equally urgent: the fate of the waste that will leave the centrals when they close from 2027. Nuclear energy is out of exit. The problem is that their waste does not know how to leave. A provisional container. The Nuclear Safety Council (CSN) has given the approval, with its conditions, to the design of the Hi-Storm FW container version G. According to the official CSN press releaseEnresa, the public company in charge of managing radioactive waste, has requested this container that will serve to temporarily store the spent Almaraz fuel, Ascó, chest and vandellós II. It is not a definitive solution, but necessary: each unit can contain up to 37 fuel elements of pressure water reactors (PWR) or 89 of boiling water (BWR), and its role will be key during the works of dismantling between 2027 and 2035. Nuclear energy turns off, but their waste needs a place – sure – while the country decides how to bury them forever. More in depth. This movement is part of something much bigger. According to The economist has detailedEnresa has officially reactivated the deep geological warehouse project (AGP), after almost three decades paralyzed. The first phase has already been awarded to the specialized consultant Amphos 21. AGP is, in simple terms, an underground nuclear cemetery. As We have explained in Xatakathe objective is to isolate waste in stable geological formations for thousands – or hundreds of thousands – of years, combining natural barriers with artificial confinement technology. According to Enresathe calendar extends until 2100, and the project is divided into eight stages that cover from initial scientific studies to the construction and eventual sealed. In early stages. Right now it is in phase one: collecting technologies, reviewing technical documentation and preparing the legislative framework that will be defined between 2026 and 2028, According to the economist. From 2029, possible locations will be selected, which will be evaluated in depth until 2039. The construction of the underground laboratory and the technical and environmental licensing process will cover up to 2059. The AGP will be operational by 2073, and will work up to 2100, when its definitive seal is expected. All this is inspired by a specific model: onkalo, The first European AGP in Europein Finland. The project is excavated more than 400 meters deep and is designed to store waste for 100,000 years, where a century will remain open and will then be sealed irreversibly. The electric, uncomfortable with the deadlines. But not everyone is satisfied with the calendar. As we already detail in XatakaEndesa, Iberdrola, Naturgy and EDP, owners of the reactors, have asked the government to advance the implementation of the AGP to 2050. The reason: they want to release the land from the centrals before and allocate them to new industrial uses. In parallel, they have resorted to the Supreme Court the rise of the “Enresa Rate”, which finances nuclear dismantling, considering it an unforeseen and unjustified extra cost. Business pressure puts a background debate on the table: Who should assume the real cost of nuclear energy once it stops producing electricity? And meanwhile? After the failure of the centralized warehouse project in Villar de Cañas (Cuenca), which He was discarded by the new general radioactive waste plan. Spain has opted for a decentralized network of Silos, one by central. However, there is a problem because these stores were not designed for more than 50 years. Therefore, initiatives such as the Hi-Storm FW container are crucial: they allow to strengthen the safety of intermediate storage and gain time while the AGP becomes a reality. And is it the only possible way? Ultimately, the best nuclear residue is the one that is not generated. Here We have talked about technologies such as nuclear fusioneven in an experimental phase, they do not generate hazardous waste. Even within the fission, there are improvement margins: molten or thorium salts reactors would allow fuel to better take better advantage and generate shorter radioactive life. But as long as those options are not profitable, the AGPs remain the only viable viable route. A long -term challenge. Spain has decided to close its nuclear stage, but the waste does not go out with the reactor. The country faces a technical, environmental and moral responsibility that will accompany us for generations. The approval of the Hi-Storm FW container and the AGP reactivation are only the beginning of a long-term race that will be played underground. And in a world that changes every decade, few decisions require thinking of deadlines of 100,000 years. The legacy of nuclear energy forces us, for the first time, to plan as if we were going to be here forever.
