plasma in a nuclear fusion reactor, in color and at 16,000 fps

by

Seeing the inside of a nuclear fusion reactor is, for obvious reasons, complicated. We are talking about temperatures of millions of degrees Celsius, hotter than the core of the Sun. However, the British company Tokamak Energy has just given us unprecedented images of what is happening inside its ST40 spherical reactor: a video in full color and at the incredible speed of 16,000 frames per second. An unprecedented ballet of colors. What we are seeing in the video is, in essence, the choreography of the elements within the tokamak. The ST40, like most of these reactors, uses hydrogen isotopes (deuterium in this case) as fuel. When this gas turns into plasma, it emits a characteristic pink light, which dominates the scene. But the interesting part begins when researchers introduce lithium, which glows red. And no, this is not just a visual spectacle. Every color, every bright filament we see in these images, is a gold mine of information that is helping scientists solve one of the biggest challenges on the long road to commercial fusion energy: how to tame plasma so that it does not degrade reactor materials. What exactly are we seeing? In the images, we see how small granules of lithium are injected into the reactor chamber. Upon entering the outer, colder areas of the plasma, the neutral lithium is excited and emits an intense crimson red light. As they penetrate the hottest and densest regions, lithium atoms lose an electron, become ionized (becoming lithium ions), and begin to glow greenish. Once ionized, lithium no longer moves freely. It is forced to follow the invisible, but very powerful magnetic field lines that confine the plasma. Those green filaments that we see dancing in the video are, literally, the lithium drawing the magnetic cage of the reactor. What is all this for? The lithium acts as a protective shield for the reactor. Recording what happens in color is not easy, but it helps identify whether the impurities that Totakak Energy is introducing into the reactor radiate in the expected place. And if the lithium powders penetrate to the core of the plasma. This experiment is part of research into a mode of operation called the “X-point radiator” (XPR) that uses elements such as lithium so that the edge of the plasma radiates and loses a large amount of heat before touching the reactor walls. It is a protective “atmosphere” that cools the plasma just at the last moment, reducing component wear without sacrificing core performance. The advancement of Tokamak Energy. This approach is the centerpiece of the Dell ST40 upgrade program, which has received funding from the US and UK energy departments. The goal is to coat all the components that face the plasma with lithium, a technique that has already been demonstrated in other laboratories, such as Princeton, to improve plasma performance. This type of visual diagnostics complement the incredibly complex systems that are being installed in reactors such as the JT-60SA in Japan, the most advanced tokamak in the world currentlywhich uses lasers to measure plasma temperature and density indirectly. A global career. While colossal and institutional projects such as ITER They mark a long-term pathwhich plans its first deuterium-tritium experiments by 2039, more agile companies like Tokamak Energy are exploring new designs and technologies, such as spherical tokamaks and high-temperature superconducting magnets, to accelerate the arrival of commercial fusion. The closure of the historic JET reactor in the United Kingdom, who said goodbye breaking an energy recordmarked the end of an era, but its legacy is the foundation on which all these new advances are built. This new window into the heart of plasma is not only visually impressive. It is a small step that brings us a little closer to the goal of replicating the energy of stars on Earth. Nuclear fusion just got a lot more colorful, and that’s great news. Image | Tokamak Energy In Xataka | While the West still waits for fusion energy, China has found a shortcut

After imposing a peace agreement in Gaza, the US is heading to Ukraine to do the same. And that has two nuclear problems

by

United States, in omnipresent figure of its president Donald Trump, seems willing to finish once and for all the invasion of Ukraine. It happens that trying to reproduce the same diplomatic “success” that is exhibited after the agreement in Gaza runs into two problems nuclear: on the one hand, the attempt to impose an agreement on Russia calls into question the sovereignty and legitimacy of the process and pushes Moscow to react. On the other hand, perhaps more dangerous, the pressure campaign that is articulated around the threat with long range missiles drastically increases the risk of an escalation that is difficult to control. From ambiguity to challenge. For a long time, Trump’s foreign policy toward Russia and Ukraine moved between deference and confusiona mix of praise for Putin, vague warnings and broken promises to kyiv. But in recent weeks, something has changed. trump has radically changed his speech, going from suggesting that Ukraine should accept territorial losses to presenting himself as the man capable of ending the war. What started as a rhetorical gesture before the UN has become a political process that seeks to consolidate the role of the United States as arbiter of the conflict, with a mix of military pressure, transactional diplomacy and calculated threat. Change and breakup. Trump, who had historically shown a almost personal indulgence towards Putin, surprised his allies and his critics with a speech in which rated Russia “paper tiger” and stated that Ukraine can recover all your territory with the support of Europe and NATO. This change, announced after his meeting with Zelensky and Macron, marks an abandonment of his traditional strategy of avoiding direct confrontations with Moscow. However, behind the turn there does not seem to be an articulated policy yet, but rather a combination of gestures: hints of sanctions, threats of retaliation and an explicit desire to reintroduce the idea of force as an instrument of negotiation. What was once indifference toward kyiv has become an instrumental interest, mixing rivalry with Putin and a desire to demonstrate international leadership. Tomahawks and ultimatums. The most visible symbol of this transformation is the word that has become recurrent in the communications from Washington: Tomahawk. Trump has openly threatened to supply Ukraine with long-range cruise missiles if Putin does not agree to reopen peace negotiations, an ultimatum which has put the Kremlin on alert. Moscow has responded calling the measure a “qualitatively new escalation” and warning that it could not distinguish whether the missiles carry nuclear warheads or not. For Trump, however, the announcement meets a double function: reinforces your image as a negotiator who commands respect and pressures Putin to prevent him from prolonging a war he can no longer win. Zelensky, for his part, sees the possibility of obtaining Tomahawks as not only a military instrument. but psychological: the threat of its use would be enough to push Russia to the negotiation table. The mere fact of discussing its delivery represents a break with the caution of the Biden erain which Washington rejected outright any action that could be considered direct aggression. From Gaza to Ukraine: export a model. The partial success of ceasefire in Gaza has offered Trump a narrative of diplomatic victory that he is now trying to convey on the European front. After freeing the Israeli hostages and achieving a temporary cessation of hostilities, the American president declared that his next objective was to “focus on Russia” and end the war in Ukraine. What is apparently a humanitarian movement also responds to a repositioning strategy global: demonstrate that Washington can impose order in both the Middle East and Europe without needing to deploy large military contingents. Trump has presented this new stage under a classic concept that has republished with pragmatism: “peace through strength.” It is the same logic that he seeks to apply with Putin (that is, not from conciliation, but from a credible threat). Ukraine, which for months feigned faith in some sterile negotiations to ingratiate himself with the White House, now perceives a window of opportunity: to replace the dialogue tables with the delivery of advanced weapons that change the balance of the battlefield. A military agreement. The visit of a Ukrainian delegation to Washington, led by Prime Minister Yuliia Svyrydenko, has sealed the new phase. The negotiators arrived with a list of valued acquisitions in 90,000 million of dollars, including Patriot anti-aircraft systemslong-range missiles and drone co-production agreements. Zelensky has learned to speak Trump’s language: that of transactions. It is no longer about asking for help out of solidarity, but rather offer “mega deals” that benefit both parties, presenting Ukraine as a profitable partner for the US military industry. The White House, in turn, has implicitly accepted that the talks with Moscow they are sold outand that only a substantial increase in military pressure will be able to force Putin to negotiate from weakness. The new strategic calculation. If you like, the Kremlin also crosses a point operational fatigue. Its territorial advances have become more marginal, and Zelensky himself has taken it upon himself to remember this in Washington with maps and figures: in a thousand days of war, Russia has barely conquered less than one percent of additional Ukrainian territory from 2022. The narrative of inevitable victory fades, and Trump seems to have understood. His speech on networks, in which stated that Ukraine is “in a position to recover his entire country in its original form,” was interpreted as confirmation of that change in perception. In other words: it is no longer about keeping a conflict frozen, but about precipitating its outcome through technological superiority and Russian economic collapse. The paradox. Paradoxically, the trump turn does not imply a return to the liberal idealism that defined US foreign policy for decades, but rather a pragmatism that mixes interests, spectacle and coercion. Washington does not seek to rebuild Ukraine, but rather to close a war that has stopped serving its image of power. From that perspective, the American president does not seem … Read more

The amount of nuclear energy generated by each country, detailed in this interactive map

by

The World Nuclear Association esteem that there are about 430 operational nuclear reactors worldwide. In full Era of renewables and the decarbonizationnuclear energy remains a important energy source for many countriesso much that China, India or France depend largely on it and even private companies resort to their “own” reactors to feed the glottone artificial intelligence. And in This interactive map We can see not only what are the countries that produce more nuclear energybut how many reactors have or the participation of nuclear in its energy mix. The US giant. The color leaves no doubt: the United States is the country that most GWH from gender nuclear energy in 2024. The estimate is 823 TWH and, although the separate data may not tell us anything, put into context represents about 30% of global nuclear energy. It is the country with more active nuclear reactors -94- and it is estimated that the nuclear participated in just over 18% of its energy mix. It is a remarkable figure if we take into account the impulse of renewables in recent yearsas well as the Importance of gas and oil in its energy matrix. And it contrasts a lot with the 85 TWH of Canada or only 12.3 TWH of Mexico, countries with 19 and two reactors respectively. China. The next darker color is China. Your case is curious because, if there is a Example of impulse to renewableswith immense importance of both wind as of the Photovoltaicbut also with the largest hydroelectric dam in the world (and another under construction), that is China. The 57 reactors in the country are estimated to generate about 450 TWH of electricity, placing themselves as the second power in this area. However, unlike the United States and other countries that we will see below, although they are investigating to have more reactors (with some latest generation on the horizon), the participation of nuclear is still very low in the Asian giant. The calculation is that less than 5% of China’s energy in 2024 arrived from a nuclear reactor. France, Top 1. The French neighbors are those who complete the podium of nuclear energy production and, if in the case of the US we talk about an important participation, in the Frenchman we have to refer to this source as fundamental. It is estimated that the nuclear generated 380.5 TWH for 2024, but the most relevant data is that 67.3% of the energy consumed by France was nuclear. With its 57 reactors, it is the country most dependent on nuclear energy worldwide. France has made huge investments both in nuclear energy and in Nuclear weaponsbeing one of the European shields in this aspectbut perhaps more attention figures from other European countries that, with less reactors, are almost as dependent as France. Slovakia (five reactors) with 60.6%, Belgium (five reactors) with 54.5%, Hungary (four reactors) with 47%, Bulgaria (two reactors) with 41%or Czech Republic (six reactors) with 40%also depend on nuclear energy. Another curious case is that of Slovenia, which has only one reactor and 35% of the country’s electricity depends on not failing. Countries ordered by its dependence on nuclear energy Blank countries. As curious as seeing what countries use and depend on the electricity generated from nuclear energy is to pass the mouse on those that are completely blank. One is Germany. If you have traveled by plane from Spain to Colonia or Berlin, you will have seen the occasional central, so it is rare to see that it does not produce electricity through nuclear. The country had its maximum in 2006, when it generated about 170 twh that would put it together with the giants of today, but after a series of political decisions and step on the accelerator after the Fukushima’s tragic accidentGermany closed all its centrals in 2023. Another absent is Australia, where it is prohibited by law. Also Italy, which prohibited it in referendums made in 1987 and 2011. Dynamic. However, all this can change. The use of nuclear energy remains a hot topic both for those who argue that it is a cleaner source of energy than coal or gas (which They seem to resurface strongly due to Consumption of data centers) as for the detractors who They allude to accidents and problems with Waste management. There are political voices in ItalyAustralia, Poland or Germany that ask for a return to nuclear energy, and the truth is that there are countries that continue to investigate to expand their “arsenal” of reactors. India, South Korea, Japan or China itself have a positive trend in the use of nuclear and it is estimated that there are about 70 reactors under construction. The interesting thing will be to take a look at this map within a few years, since among the plans for Reactivate nuclear centrals that meet the needs of the technological industry, the increase in Investment in giants such as India or China and research in SMR reactors and of nuclear fusionthe panorama can change a lot in the coming years.

Build the first closed cycle nuclear reactor

by

Vladimir Putin has announced what he calls the “first nuclear energy system in the world with a closed fuel cycle”, a technology that promises to reuse up to 95% of nuclear fuel. If it materializes by 2030, as stated by the Russian president, Russia would dodge two of the greatest challenges of current nuclear centrals: the Radioactive waste management and the possible exhaustion of uranium reserves. Uranium? What do you want that. In the Moscow Global Atomic Forum, and before the presence of figures such as Rafael Grossi, director of the OIEA, Putin described the Russian reactor of closed cycle as a “truly revolutionary development” that, in his words, “will eliminate the problem of uranium supply.” The centerpiece of the ambitious Poryv project (“advance” in Russian) is a rapid reactor refrigerated by lead called Brest -od-300, which is being Building in Severska city in the Siberian region of Tomsk. In the same complex, called Odek, Russia will also build the modules for the spongery and reprocessing of the irradiated fuel. 95% recoverable. In addition to using molten lead instead of water as refrigerant, the Brest-O-300 reactor is designed to operate with uranium-reputony nitruro as fuel. It is its in situ integration with the sponge and reprocessing modules that will allow closing the nuclear fuel cycle. According to official statements, this system It will allow 95% of the spent fuel to reusea technically consistent figure with the external reprocess processes, where most of the fuel used (uranium and plutonium) ends up being recovered. The remaining 3-5% corresponds to fission products and minor actinids, which remain high radioactivity residues. It is not a new technology. Countries like France and Russia itself Nuclear fuel already reproces at an industrial scale. And Japan intends to join the club with the Rokkash Plant. However, the Russian project is a pioneer in its attempt to create a fully integrated complex where a fast reactor operates in symbiosis with its own fuel manufacturing and recycling facilities in the same place. If Russia meets its deadlines, you could have The first complex of this type in operation. And to support him, he has established an International Research Center in the Uliánovsk region (the MBIR International Research Center in Dimitrovgragra), inviting scientists around the world to collaborate in what Putin has called a “new era in nuclear energy.” But is uranium running out? Putin’s justification for this strong investment is a future with uranium shortage. During his speech, he cited OECD estimates that suggested a possible exhaustion of uranium resources by 2090, or even before: as soon as in the 2060s. However, the “Red Book” of the OEA does not speak of an exhaustion of uranium, but of An increase in demandwhich could produce tensions in the supply between 2080 and 2110 if significant investments are not made before for the opening of new mines. Russia’s plan It is a strategic bet. If you achieve the closed cycle reactor for the 2030s, we could witness a new way of understanding nuclear energy, and a world with limited resources in which Russia has managed to outdo the rest.

The amount of nuclear energy generated by each country in the world, exposed in this graphic developer

The use of nuclear power It is still one of the most controversial issues in the energy debate. It is worldwide due to economic, social factors and concern for something very concrete: Waste management. It seemed like him Huge deployment of renewables would end the debate, but the truth is that there are countries that follow depending greatly on nuclear energy. And this graph reflects it clearly: Three blocks. The graph is the work of Visual Capitalist with data of the ‘Energy Institute Statistical Review of World Energy’ and the estimate is that nuclear plants generated 2,818 THW of electricity in 2024. Approximately 10% of the electricity generated worldwide during the world during the last year, but beyond the total, which allows us to see is that there are three very even and perfectly identifiable blocks. On the one hand, that of the United States and Canada. Here Canada has ‘little’ to say, and also its centrals generated 3.6% less than the previous year, but The United States is still a giant. It generated 823 TWH that, put in context, represents about 30% of all global nuclear energy. It has 94 operational reactors and that huge amount of electricity accounted for 18% of the national total. In the Asian block we have China standing out With 451 TWH produced, 3.4% more than the previous year, South Korea with 189 TWH and both Japan and India contributing, but with lower productions. And in the European bloc, France and Russia stand out above all, which among them have a much more similar production. The interesting thing here is to see the speed at which the world in a nuclear question moves. Promoting nuclear. Because we have already seen that, although the US generated more electricity with the nuclear, it was a small percentage. If we look at the European block, we have that there are those who grow 4% (Sweden) and who decreases 4% (Spain), But we have a France that increased the production of its centrals by 12.2%. With 57 operational reactors, if there is a country that depends on nuclear energy, that is France. HE esteem that 67% of its electricity comes from nuclear. Countries such as Slovakia, Belgium, Hungary or Bulgaria also depend largely on nuclear energy. In the case of Spain20% of their energy comes from these centrals. But if we look at the Asian block, the thing changes. China impulse Its nuclear generation These last monthsbut Japan did it in 9.3% and India, who wants to consolidate as a new technological core worldwide, generated 13.3% more. In the Middle East highlights United Arab Emirates that, whose four reactors generated 22% of their electricity. Old reactors. In total, I know esteem That there are 416 operational plants worldwide (France has the same as China, a fact that reflects the importance for the neighboring country) and a problem is that most are quite old reactors. Around two thirds of them are over 30 years old and, although the estimated life is usually between 30 and 40 years old, it is easy to prolong it more time with modifications and extensions. New reactors. There are also about 70 reactors Under construction. They are distributed, but most are concentrated in Asia, especially in the two countries that are leading that world nuclear expansion: China and India. New reactors use refrigerants that can operate with more energy safety and efficiency, also generate less waste and have an estimated useful life of more than 50 years thanks to modular designs. As we say, China is one of the countries that is best betting on this energy (despite the impulse that is also giving to renewables), and within its new plants, the fourth generation reactors stand out, like the one used by molten salts or thorium. They are not the only ones, as the US, France and India are also investing in research programs to develop reactors that generate electricity from the thorium (three times more abundant than uranium) Data centers. The truth is that, although sources like RENVOABLE EXPOSEDit seems that We are far from folding both fossil fuels and to nuclear energy. Much of the fault is very demanding data centers in energy terms that even need Punctual gas supply or even coal in demands of demand peaks. In fact, some of the main technological ones such as Amazon, Google or Microsoft announced Plans to create or reactivate nuclear centrals to satisfy the energy need for your data centers for artificial intelligence. And all this while we look at a future in which the norm should be the SMR reactors… And the nuclear fusion still is on the horizon.

Nuclear fever goes faster than centrals

by

Uranium, for years relegated to a corner of the raw material market, Live a rebirth. His prices have shot themselves and investors chase him with enthusiasm, convinced that nuclear energy will be key in an electrified world. As Jennifer Hughes said in the Financial Times: “Investors in Uranium and scientists should have much in common: both seek great benefits from a small starting point.” However, this financial euphoria collides with an awkward reality: nuclear power plants are not built to the necessary rhythm and bottlenecks are huge. A small and overwhelmed market. The spot price is around 76 dollars per pound, After having exceeded $ 100 at the beginning of 2024. Much of this increase is explained by a small market: most uranium is sold under long -term contracts and the immediate market space is very narrow. At the same time, governments accumulate strategic reserves. In the podcast Stock Movers Bloomberg They detailed that The US Secretary of Energy, Chris Wright, wants to strengthen national inventories to reduce Russia dependence, which provides a room of enriched uranium that feeds the 94 US reactors. The result is clear: more uranium is purchased than the centrals can consume today, a sign that the geopolitical and financial appetite goes ahead of the real capacity. A spark that lights nuclear fever. Why this boom? The explanation is in global electrification. According to Bank of America analysts, by the end of this decade the world consumption of electricity will increase to 30%driven by the electrification of transport and the rise of AI data centers. According to the International Energy Agencythe data centers already consume about 415 twh per year – 1.5% of global electricity – and their weight will continue to grow with the expansion of AI. In fact, Nvidia, Microsoft, Google, among others need abundant, reliable and carbon free energy to support their operations. Hence, technology companies have taken an unusual step: Bet on nuclear. The turn of many countries. Nuclear energy has returned strongly, even in countries that had a firm predisposition to the closure. Germany He stopped his nuclear blackout plan and Belgium made the same decision. Indonesia, despite its wealth in coal, included nuclear in An energy investment plan of 235,000 million dollars. And the United States He has decided to quadruple nuclear capacity recycling uranium. Today there are about 440 reactors in operation in the worldwhich contribute about 10% of global electricity and are the second low carbon energy source after hydroelectric. The wall of reality: the deadlines. Political promises collide with industrial limitations. The projects are usually expensive and slow, with deadlines that do not fit with the climatic urgency. To this are added concerns about radioactive waste and fear of accidents such as Fukushima, Although even Japan is willing to return. In fact, in the US, only three reactors have been built in the last quarter of a century, two of them with exorbitant costs and significant delays. Today there is no plant under construction and to meet the objectives of Washington it would be necessary to initiate the works of 20 medium -sized reactors every year, According to Morgan Stanley calculations. Even China, famous for its speed When he decides to investit takes between five and ten years to design, approve and complete a new plant. Russia, the bottleneck of the nuclear cycle. The big problem is in the phase of the nuclear cycle that converts the mineral into useful fuel. There, Russia is the dominant actor. Although countries such as Australia (28%of world reserves), Kazakhstan (13%) and Canada (10%) large uranium deposits concentrateonly Russia Master the enrichment on a global scale. Canada emerges as an alternative. With mines in the Athabasca basin, the country not only extracts but can also enrich uranium, which makes it a “safe and reliable” supplier. His new mine, operated by Nexgen, could move to Kazakhstan as the world leader of production in the next decade. For its part, this last country accelerate your own nuclear plans. Kazakhstan has among his plans to build his first central in ülken, with financial support from Russia but technological alliances with France and South Korea, in an attempt to reduce the dependence of the Kremlin. Expectations ahead of reality. Uranium has gone from being a forgotten resource to become a central file of the energy and geopolitical board. Prices reflect it and investors bet strongly. But nuclear infrastructure slowly advance, the dependence of Russia in the fuel cycle continues to weigh and social resistances remain alive. As the energy expert warns in its columnwho invest in Uranium expect “too much, too soon.” The true nuclear energy boom, if it arrives, will take much more than a rebound in contributions.

The United States needs nuclear energy for AI and already knows where to find it: in dismantled atomic bombs

by

The rivalry between China and the United States is not only freed in markets or The tariffs. It is also played In the field of energy. And, in full rise of artificial intelligence, Donald Trump has decided that the way to ensure abundant and stable electricity for military bases, laboratories and data centers will be through nuclear energy. His plan is as ambitious as controversial. An explosive plan. The Trump administration has sought to quadruple the nuclear production of the country. To do this, the White House wants the new reactors not to depend solely on fresh uranium, but also on recycled fuel from radioactive waste and the military plutonium surplus dismantled eyelets. As Washington Post explainedit is an “national security imperative.” The idea is simple: guarantee a stable supply for the most sensitive infrastructure, from military bases to AI data centers, without depending on the electricity or imported fuels. The recycling now an ally. THE ENERGY DEPARTMENT has identified in its inventories All uranium and useful plutonium to reconvert it in fuel. Among them is the plutonium from dismantled weapons, one of the most dangerous materials on the planet. To make it possible, startups like oklo and curio They work in piroprocessinga method that introduces fuel bars spent on molten salts and uses electricity to separate the usable components. Unlike the chemical processes used in the past, these companies ensure that the technique is safer, more economical and less polluting. In addition, Oklo, backed by Sam Altman, founder of Openai, has announced an investment of almost 1.7 billion dollars in an advanced fuel center in Oak Ridge (Tennessee), the same land where uranium was enriched The Manhattan project Eight decades ago. Only the tip of the iceberg. A couple of months ago, in one of the executive orders signed by Trump forced the Nuclear Regulatory Commission (NRC) To complete any reactor license in 18 months, when until now the process could take more than a decade. The White House also ordered to rewrite the rules of radiation exposure, considered “excessively cautious.” The official statement issued in May established specific deadlines: The Army must operate a reactor at a national base before September 2028, and the energy department will have to inaugurate at least one advanced reactor in any of its facilities in 30 months to supply AI data centers. To this is added the release of 20 tons of Haleu (high -rehearsal low enrichment uranium) for new reactors and the intention of signing 20 international nuclear cooperation agreements in the current congress. The depth of the matter. Despite political and business enthusiasm, the scientific community contrasts with reality. Ross Matzkin-Bridger, exassor of the Department of Energy, He pointed out that it is “The same technologies that developed and rejected decades ago”, with the same background problems. The MIT physicist and former secretary of Energy, Ernest Moniz, It was more blunt: recycling plutonium of arms not only makes nuclear energy more expensive, but also “threatens to create material that can be used in pumps.” Along the same lines, Matthew Bunn, from Harvard, considers it unrealistic to think that public opinion accepts reprocessing plants that would also require their own waste deposit. And Frank von Hippel, from Princeton, recalled that the US has already abandoned civil recycling at the time of Jimmy Carter, after India used that technology To manufacture your first bomb. Not everything is warnings. For the White House, nuclear recycling is a strategic tool. The official statement insists that AI data centers and military facilities need “Dense energy sources, safe and resistant. ” Also, defenders such as Bradley Williams, from the National Laboratory of Idaho, They argue that using recycled plutonium It could become a need to guarantee sufficient fuel. And startups ensure that new processes include safeguards that prevent reuse of that material for military purposes. The weight of waste. The matter is even broader because the country already accumulates about 90,000 metric tons of fuel spent, stored in containers in active and dismantled plants, According to The Washington Post. Recycling part of that material would relieve a dilemma that has been resolved decades. Meanwhile, the private sector tries to position itself. Oklo signed a contract with Switchdata centers operator, to build modular reactors that contribute up to 12 GW before 2044. The company promises to open its first reactor, Aurorain 2027, although the agreement is not binding and the NRC rejected its previous application in 2022. The idea of ​​recycling is not unique. More countries have found in this method in a way to find a more source without depending on other countries as the case of Francewhich does so through subsidies and strict security measures. For its part, Japan accumulate delays and cost overruns In its Rokkash Plant, which has not yet produced fuels after decades of development. At the opposite end, United Kingdom decided to abandon the idea of ​​recycling. With about 140 tons of stored civil plutonium, he has chosen to immobilize him in a solid and stable way to bury him in a deep geological warehouse in Sellafield. Something similar occurs in Spain, which has reactivated his plan For a deep geological warehouse, planned for 2073, and in the meantime use containers such as Hi-Storm FW for intermediate storage. The contrast is evident: while some countries try to give new life to waste, others bury them forever. Everyone looks for the same: prevent nuclear legacy from becoming an eternal problem. Forecasts. The United States is committed to resuscitating old nuclear recycling technologies to sustain its energy safety and the AI ​​career. The defenders see it as a historical opportunity to reduce foreign dependence and give new use to forgotten materials. Critics fear that the same failures and risks of half a century are repeated. The experience invites prudence: the last reactors connected in the USA, In the Vogtle (Georgia) plantthey arrived seven years late and 17,000 million dollars of extra cost.

The US already proves its new “Airplane of the Last Judgment”. His role is to keep the command chain even in a nuclear scenario

by

The most resilient aircraft in the United States has just written a new chapter in a story that started half a century ago. The Air Force and Sierra Nevada Corporation They have launched the First flight tests of E-4C SAOC, direct successor of the E-4B Nightwatchthe family of “Final Judgment” that guarantees the continuity of command even in the worst scenario. Recently, a giant based on a Boeing 747-8he first took off from Dayton, Ohio, opening a trial campaign that will last in the coming months and that opens the transition to a more modern fleet. With this step, the North American country begins to replace flying bunkers that approach at the end of its useful life. It is not a new concept: we talk about the evolution of a system that combines government continuity, safe communications and nuclear deterrence. The SAOC program, with a contract of More than 13,000 million dollars Awarded in 2024, it is a change of method in the Pentagon: for the first time, the original manufacturer of 747 does not lead the integration and responsibility falls to a company specialized in large conversions, which has brought together first level partners to build the most advanced command plane of its time. That inaugural flight is the first step of a decade of work to deliver a platform capable of continuing to operate when everything else fails. A new chapter for the most strategic plane in the United States The SAOC (acronym for surviving Airborne Operations Center) is the most ambitious Air Force project to reinforce its network of Nuclear control, control and communications. Its mission is clear: to ensure that, although the strategic centers on land remain unused, the country’s leadership can coordinate a military response and Maintain control of the armed forces from the air. It is no accident that these aircraft are known as “final judgment planes”: they are designed to be the last resort in a scenario where everything collapses, operating as a true flying pentagon. The first generation of this platform, the E-4B Nightwatch, entered service in the seventies on the basis of a Boeing 747-200. Currently, the United States maintains four units Active, all deployed in the Offutt Air Base, Nebraska. Despite their robustness, the passage of time passes by an invoice: each plane has decades in service, the spare parts are increasingly difficult to get and Its availability is barely 55%. Keeping these giants operational is a expensive task, and the Air Force plans to remove them at the beginning of the next decade. The renewal is already underway. Sierra Nevada has received four of the five Boeing 747-8i acquired from Korean Air, and in them are applied deep modifications. Dayton, Ohio, and Wichita, Kansas They concentrate the Conversion and test operationswhich will be extended at least until 2026. This staggered plan will allow the new aircraft to enter into service while the E-4B begin to withdraw, always maintaining an operational nucleus that ensures the continuity of government. A E-4B Nightwatch currently operational The technological jump is evident. The 747-8 is the last large commercial aircraft of four engines made in the United States, with greater fuel capacity, more efficient engines and a broader fuselage than its predecessor. These characteristics make it the ideal base for an airplane that needs to sustain prolonged operations with refreshing in flight. The 747-8 cell also provides growth margin to integrate advanced communications, reinforced armor and redundant systems, all designed to survive electromagnetic pulses or cyber attacks. E-4B Nightwatch Decades of antiquity in flight At an industrial level, the program also makes a difference. Although Boeing remains the original 747 manufacturer and provides structural support, this time does not lead the project: the Air Force opted for an open data model to ensure that the government owns the design and can modify it in the future without depending exclusively on the OEM. Boeing It was out of the bid in 2023 after disagreements on the terms of the contract and data rights, which opened the door to Sierra Nevada Corporation as the main contractor. The company, known for its high complexity projects, has formed a team with giants like Lockheed Martin, Collins Aerospace and Rolls-Royce to create an unprecedented platform in the military. His role in recent history reinforces the need for this investment. E-4B have participated in critical events: from government continuity exercises to emergencies such as September 11, 2001 attackswhen at least one of these aircraft took off to provide safe communications in the middle of chaos. These aircraft have routinely accompanied the Secretary of Defense on International Travel, remain on alert during presidential speeches to Congress and act as a support network when national security protocols are launched. In the popular imaginary they appear little, but their mere existence is part of the United States deterrence strategy. The E-4C SAOC is, more than an update, a long-term bet. The contract signed with Sierra Nevada is It extends until 2036which reflects the magnitude of the technical challenge and the necessary time to complete the conversion of the aircraft, certify and deploy them fully. With this plan, the United States ensures that the most critical piece of its system of Nuclear control and control It will remain in force for decades. Although many details, such as the exact equipment of antennas and systems, are still classified, what is already underway is a clear message: the ability to direct the country in a global crisis depends on a strategic investment that seeks to always have a command center in the air.

The OIEA finds evidence of the secret nuclear reactor of Syria

by

In September 2007, Israeli combat aircraft reduced a complex in the Syrian desert of Deir Ezzor to debris. Israel said that there was a nuclear reactor there with the help of North Korea. The Bashar al Asad government replied that it was nothing more than a military base. For years, both versions met in the field of suspicion. Now, eighteen years later, the International Atomic Energy Agency (OIEA) provides evidence that incline the balance: in that place there was processed uranium. A few particles. According to a confidential report quoted by APNewsthe agency’s inspectors found “a significant amount of natural uranium particles” in one of the three sites examined in the last two years. As Reuters has pointed outit is not a rich uranium, but of anthropogenic origin: it had gone through a chemical process. “The analysis indicated that uranium occurred as a result of chemical processing,” the document said. According to Apnewssome of these particles coincide with the conversion of mineral concentrate into uranium oxide, a usual step in fuel production for reactors. A nuclear plan never recognized. The history of this “ghost reactor” begins in 2011. The OIEA had already estimated that the building destroyed by Israel was “most likely a nuclear reactor that should have been declared” by Syria. According to Apnewsthe installation would have been built with the support of North Korean engineers, which would explain the secrecy of the Bashar al Asad regime. Rafael Grossi, current director of the OIEA, acknowledged in statements collected by the news agency that some of the Syrian activities “were probably related to nuclear weapons.” However, Damascus always denied it. After the Israeli bombing, he leveled the land of Deir Ezzor to erase traces and refused to fully answer the questions of the international organism. The fall of Al-ásad. The turn came with the end of the Bashar al Asad regime, overthrown last year After almost three lustra of civil war. The new interim government, led by Ahmed al Sharaa, agreed to cooperate with the UN Nuclear Agency. Besides, As Reuters has had accessin June the authorities allowed for the second time the taking of environmental samples. It was not a linear process. According to The IndependentAsad’s departure temporarily interrupted the investigation: “We are still evaluating what we find there and we have a large questioning sign, because we do not have an interlocutor,” Grossi admitted in December 2024. With the restoration of contacts this year, the OIEA is optimistic: “Once the results are evaluated, it will be possible to resolve the pending issues related to the past nuclear activities of Syria.” A region marked by proliferation. Beyond the Syrian case, the findings are registered in a region marked by the shadow of nuclear proliferation. As we have pointed out in XatakaIsrael has bombarded on different occasions facilities in Iraq, Iran and Syria under the argument of preventing their enemies Develop atomic weapons. Grossi himself warned Bloomberg statements that the power vacuum in Syria opens the risk of looting nuclear materials in research centers. A civil nuclear future for Syria? Paradoxically, the new Syrian leadership has expressed interest in exploring a civil nuclear program. According to Al Jazeerathe interim president Al Sharaa discussed with the OIEA the possibility of resorting to small modular reactors to generate energy and asked for help to rebuild nuclear medical infrastructure, devastated by more than a decade of war. The OIEA has expressed willingness to collaborate in these areas, always under a transparent framework of safeguards. A file to close. The history of Deir Ezzor reactor seems to reach its final chapter. What began as a bombing wrapped in controversy and denials is now corroborated with scientific evidence. The OIEA insists that the new samples will allow the case to close, but the questions persist: How far did the Syrian clandestine nuclear program really arrive? What external actors fed him? And can a country devastated by war reorient its relationship with nuclear energy towards peaceful uses? Eighteen years after the Israeli attack, the ghost reactor is no longer a rumor: it is the proof of a secret that Damascus tried to bury in the desert sand.

Citizens were not supposed to pay the closure of the nuclear, but there is already a hole of 11,600 euros on the bill

by

Closing nuclear is not just a political decision, but also an economic problem. The dismantling bill and radioactive waste already exceeds 20.3 billion euros, and the debate between electric and government has only started. An invoice that does not stop growing. According to Enresa’s memorythe public company in charge of dismantling, the total expected cost already reaches 20,367 million euros. The majority corresponds to the dismantling of the reactors, with 17,520.5 million, while waste management and spent fuel, the so -called “electric rate”, adds 2,846.8 million. The rest of the activities, such as the management of the enusa fuel factory in Salamanca, complete the invoice. The fund that finances these operations, nourished with contributions from the electricity, accumulated 8,677 million at the end of 2024, after the 30% rise in the valuation rate since July of last year. This means that it only covers 43% of the planned cost, leaving in the air a gap of 11,690 million euros still to finance. The plan that changed everything. The 7th General Radioactive Waste Plan (PGRR), Approved at the end of 2023was a change of stage by definitely abandoning the centralized temporary warehouse project (ATC) in Villar de Cañas. Instead, waste has been chosen in independent temporary stores (ATI) located in each central, waiting for deep geological storage (AGP) that should be ready in 2072. The PGRR extends the forecasts up to 2100 and delays the total closure of the nuclear park until 2035with Trillo and Vandellós II as the latest plants in going out. To this is added the legal obligation to annually review the forecasts, which adjusts the costs to inflation and the new technical conditions. Electric against rates. The companies, headed by Iberdrola and Endesa, say that operating under this cost scheme is unfeasible. Both have presented resources in the courts against the increase of 30% of the Enresa rate and have claimed millionaire compensation. Besides, They have requested that the closing calendar be reopenedarguing that prolonging the useful life of the reactors would relieve pressure on the electrical system. According to a report by the consultant EY cited by Nuclear ForumSpain supports the highest nuclear fiscal burden in Europe, with 27.3 euros per megavatio hour in specific encumbrances, which in the opinion of companies places them at a clear disadvantage against other countries. The red line of the government. The Executive maintains its position: the costs of dismantling and management of waste will not fall on consumers. The minister for ecological transition, Sara Aagesen, has responded to electricity with three conditions for any extension of the nuclear park: that does not involve additional costs for citizens, that supply security is guaranteed and that plants strictly comply With the standards of the Nuclear Safety Council (CSN). The Government insists that there are no formal negotiations to extend the lives of the centrals and accuses companies to try to transfer their invoice to the whole citizenship. The Secretary of State for Energy, Joan Groizard, summarized the position In statements collected by eldiario.es: “They want part of the dismantling costs to be paid among all, and we will not transfer it to the whole citizenship.” Forecasts and uncertainties. Costs can continue to grow. The French case is a notice as they have advanced at eldiario.es: The Andra agency reviewed in 2025 the cost of the AGP Cigéo between 26,100 and 37,500 million, an increase of up to 60% compared to 2016. In Spain they have prepared The 9th R&D Plan (2024-2028) of Enresa It includes 31 million in research to develop containers, confinement materials and recover fuel. A modest figure compared to billions at stake, but key to preparing the future AGP of 2072 and reducing long -term risks. In addition, Spain faces this solo calendar within Europe. While France, Sweden or Switzerland choose to expand the life of their reactors or even promote new projects, the Spanish PGRR maintains a plan of Progressive closure without planned extensions. A debate that goes beyond closing. The balance of the electrical system is also present. This summer a paradox has been evidenced: historical record of solar production in Europe, but invoices fired by the lack of storage and the need to resort to gas in night hours. In that hole is where the nuclear has played so far a stable backup role, but does not solve that background problem: it only postpones the closure, it makes the costs more expensive and aggravates the inheritance of waste. The dilemma is clear: can you do without it before the network is prepared to guarantee the same stability without firing the price of light? For the Government, the response is to accelerate renewables, storage and interconnections. For electricity, to keep the nuclear live longer.
