Japan has attempted to power up the world’s largest nuclear power plant. It only lasted a few hours

by

The nuclear debate, which Japan thought closed, returns to the scene. The recent authorization to reactivate Kashiwazaki-Kariwa, the largest atomic plant in the world, has set off alarms: citizen distrust, the shadow of Fukushima and doubts have surfaced about whether TEPCO (Tokyo Electric Power Company) is the right company to lead the country’s new energy stage. Fifteen years of waiting for a reboot that didn’t even last a day. In Niigata, reactor number 6 went from complete silence to emergency shutdown in less than 24 hours. The failure, located in critical safety systems, has turned the great revival energetic of Japan in a lesson in technical fragility. A slow giant. Kashiwazaki-Kariwa had not produced a single kilowatt since 2012. That closure was not an isolated event, but the shock wave of Fukushima in 2011, which put all reactors of similar design in the spotlight. But for TEPCO, this complex of seven units and more than 8,000 MW is much more than energy: it is its financial lifeline. According to Japan Forward estimatesthe electricity company needs these reactors to inject some 100,000 million yen annually into its coffers, essential oxygen to pay the endless bill for the dismantling of Fukushima Daiichi. The Japanese Government, under the command of Prime Minister Sanae Takaichi, has positioned this reopening as a strategic pillar. The objective is ambitious, in saying that nuclear energy represent 20% of the energy mix by 2040. This energy is needed to power new AI data centers and semiconductor factories, thus reducing dependence on imported fossil fuels, made more expensive by the fall of the yen and current geopolitics. Chronicle of a fleeting reboot. The reactivation process of reactor No. 6 was marked by setbacks even before it began. The restart, initially scheduled for Tuesday, January 20, had to be postponed one day after it was detected that an alarm designed to warn of the accidental removal of control rods did not work during the tests, as reported by The Japan Times. After correcting this error, operations formally began on Wednesday at 7:02 pm. At 8:28 pm, the reactor reached the “critical state” (sustained nuclear fission). However, the celebration in TEPCO’s control rooms – where staff tensely monitored screens – was short-lived. At 12:28 a.m. Thursday, just 16 hours after the start, an alarm sounded again. This time it indicated a failure in the engine control panel that operates one of the reactor control rods (the devices that regulate or stop the nuclear reaction). TEPCO attempted to replace electrical components and inverters, but the anomaly persisted. Given the uncertainty, the company announced a “planned temporary shutdown” to reinsert the control rods and stop the fission, a process that concluded Friday morning. “We do not assume that the investigation will be resolved in one or two days; at this time we cannot say how many days it will take,” admitted Takeyuki Inagaki, director of the plant, at a press conference. Security under suspicion. Although TEPCO maintains that the reactor remains under control and without leaks to the outside, the incident has served to poke into a wound that was never closed. It is not just the present that is worrying, but a tarnished record: just five years ago, the Financial Times I already put the focus on the plant after a security scandal where an employee circumvented access controls using a foreign identification, revealing the fragility of its surveillance systems. However, distrust does not only fall on TEPCO. The Japanese nuclear sector is experiencing a systemic credibility crisis. Earlier this month, Chubu Electric admitted to manipulating seismic data to minimize the impact of potential earthquakes at its Hamaoka plant, leading the Nuclear Regulatory Authority (NRA) to describe the act as “scandalous” and to suspend its security review after a decade of paperwork. A divided society in Niigata. Outside the plant and at TEPCO headquarters, protesters like Yumiko Abe, 73, express their indignation: “Electricity is for Tokyo, but we in Kashiwazaki run the risk. It doesn’t make sense.” The figures support this discomfort. According to surveys cited by South China Morning Postabout 60% of Niigata residents oppose the restart. Furthermore, 70% of citizens fear that TEPCO will not be able to manage an emergency based on its history. On the other hand, prominent seismologists warn in the Financial Times that the plant is located near an area of ​​very high seismic risk where a large earthquake could cause billions of dollars in damage. The future of the atom in Japan. The path to full operation of Kashiwazaki-Kariwa is once again up in the air. While TEPCO makes cost cuts of 3.1 trillion yen To fund the decommissioning of Fukushima, the NRA has promised strict on-site inspections to verify corrective actions following this latest failure. Experts like Dr. Florentine Koppenborg suggest that this “nuclear renaissance” It could be just a “drop in the ocean” as security costs have skyrocketed and public trust remains at rock bottom. Japan is at an energy crossroads: the urgency to decarbonize and feed its technology industry collides head-on with the memory of a disaster that, 15 years later, is still very present. The Kashiwazaki-Kariwa giant has shown that, in nuclear energy, the distance between strategic success and technical failure is measured in the sound of a single alarm.

Nuclear energy has generated electricity for decades. China is reinventing it for something else: the industry

by

For decades, nuclear power plant cooling towers symbolized one thing: electricity. However, off the coast of Jiangsu province, China has just begun a maneuver that will change the usefulness of fission. It’s no longer just about turning on light bulbs; It is about feeding, with clean steam, the voracious thermal heart of heavy industry. The first concrete of a new era. According to China National Nuclear Corporation (CNNC)the first concrete was poured for the nuclear island of Unit 1 of the Xuwei project. This act is not just another procedure, it is the first nuclear project to break ground in the inaugural year of China’s 15th Five-Year Plan, symbolizing a strategic shift towards diversified energy applications. The project, developed by CNNC Suneng Nuclear Power, is strategically located near the Lianyungang petrochemical hub, an area that requires a staggering 13,000 tons of steam every hour to maintain its operations. The concept of the super boiler. Xuwei’s great innovation lies in its technical architecture. As explained by Global Timesthe project is the first in the world to couple two different generations of reactors to maximize thermal efficiency: The Hualong One (Generation III): Two units of this pressurized water reactor (PWR) provide the base heat to convert demineralized water to saturated steam. The High Temperature Gas Cooled Reactor (HTGR – Generation IV): This unit acts as a “super boiler”. The steam produced by the Hualong One is superheated a second time by the primary steam of the HTGR, reaching the necessary extreme temperatures. for complex chemical processes such as petroleum refining, distillation and cracking petrochemical. This “double coupling” system allows, according to NucNetthat the plant will be useful for applications ranging from refining to desalination and steel production, sectors that have traditionally depended exclusively on fossil fuels. Cleaner than coal. The urgency of this project responds to a critical climate need. The petrochemical industry is one of the most difficult sectors to decarbonize due to its constant heat demand. The figures provided by CNNC yvsupported by media such as World News Nuclear They are compelling: once the first phase is operational, the plant will supply 32.5 million tons of industrial steam per year. This will reduce standard coal consumption by 7.26 million tons and avoid the emission of 19.6 million tons of CO2 annually. Advances in cutting-edge technology. To manage the complexity of joining two very different types of reactors, Chinese engineers have turned to Artificial Intelligence and robotics. The design team used hierarchical digital simulations to create the system’s control logic, allowing heat and electricity to be balanced based on grid and industry demand. In the field of construction, progress is not minor. Li Quan, project manager, explained to Global Times that automatic metal active gas (MAG) welding systems with intelligent laser tracking are being used, a technology three times more efficient than manual welding. In addition, they emphasize that the localization rate of equipment (100% Chinese technology) exceeds 95%, promoting a national high-tech supply chain. Towards a global standard? Beyond its borders, China sees Xuwei as an export model. The CNNC has described the project as a “Chinese solution” for the low-carbon transformation of energy-intensive industries around the world. The goal is to demonstrate that heavy industrial development does not have to be tied to coal smokestacks. This move aligns with the 2025 white paper titled “China’s plans and solutions for carbon neutrality”which advocates for safe and orderly development of nuclear energy not only for the electrical gridbut for clean heating and desalination. The European contrast. While China is betting on nuclear energy to power heavy industry, in Europe the approach to waste heat is taking a digital path. Cities like Helsinki are finding an unexpected source of heat: data centers. As we have explained in Xatakacompanies like Telia or Microsoft are recovering up to 90% of the heat generated by their servers to inject it into district heating networks (district heating). A single data center in Finland can heat up to 20,000 homes. Although the scale is different – ​​China seeks heat to make steel and plastics, while Finland seeks shelter for its citizens – the philosophy is identical: in a world in climate crisis, wasting heat is a luxury that no one can afford anymore. Both models demonstrate that the energy transition depends on taking advantage of every calorie produced, whether it comes from a uranium core or an artificial intelligence processor. The end of thermal waste. The start of work in Xuwei marks a turning point. As the CNNC analysis concludesthe project is a “strong and clear beat” towards deep decarbonization. China is trying to show that nuclear power is the missing piece of the puzzle to reconcile mass industrial production with net-zero emissions goals. If Xuwei’s model is successful, the image of the nuclear power plant as an isolated island that only produces electricity will become history. The future of the atom seems to lie, rather, in its ability to become the invisible “heat engine” of modern civilization.

The US has just started live-fire exercises with its nuclear aircraft carrier. And it has done so in the waters claimed by China

by

Since the end of the Cold War, the naval presence has been one of the pillars of the United States’ strategic balance in the Asia-Pacific, an architecture designed to guarantee open trade routes and deter unilateral changes to the status quo. However, the rise of Beijing as a maritime power and the transformation of the South China Sea into one of the most disputed spaces of the planet have turned each naval movement into something more than a simple military routine, loading it with readings of all kinds. That’s why Washington’s latest move is so important. A deployment with high strategic value. The deployment of the nuclear supercarrier USS Abraham Lincoln At the end of November it occurred with a almost total discretionwithout official statements from the Pentagon or public indications about its area of ​​operations, a common practice when the US Navy wants to preserve freedom of strategic maneuver. This silence coincided with a moment loaded with internal symbolism, as Abraham Lincoln took over from USS Nimitzthe dean of the fleet, who returned to the United States after completing his last operational mission before beginning a long process of retirement and recycling. The handover is not a simple exchange of platforms, but rather a visualization of how Washington maintains its global presence seamlessly while orderly renewing the core of its naval power. Guam as a logistics anchor. It we have counted before. The battle group’s stopover in Guam reinforced the island’s role as one of the less visible pillars, but more decisive of US military architecture in the Indo-Pacific. Guam works like an advanced node from which prolonged operations are sustained, large units are resupplied and forces deployed thousands of kilometers from the continental territory are coordinated. That Abraham Lincoln was the second aircraft carrier to visit the island in a few weeks stressed the importance of this enclave at a time when the USS George Washingtonthe only aircraft carrier permanently based in Japan, remains out of commission for maintenance, demonstrating that asset rotation does not imply a real reduction in presence, but rather a carefully calculated redeployment. The “routine” in the South China Sea. The subsequent entry of the Abraham Lincoln into the South China Sea is part of an American strategy long term based on the normalization of its naval presence in waters that Beijing considers its own. Washington is not looking for a specific gesture or a spectacular demonstration, but for something more subtle and persistent: to operate regularly to prevent absence from consolidating territorial claims through deeds. By presenting these activities as routine, the United States intends reduce capacity of China to define the narrative, keeping open sea lanes that are essential for global trade and regional strategic balance. Demonstration of capabilities without escalation. During its recent activity, the combat group has integrated live fire exercisesresupply operations at sea and flights of the F-35Cthe fifth-generation shipborne fighter, composing a complete picture of its operational capability without resorting to explicit political messages. Added to this are tests of defensive systems like the Phalanx and the escort of Arleigh Burke destroyerscapable of operating in anti-aircraft, anti-submarine and land attack missions. The package conveys a clear signal of preparedness and self-reliance, one based on observable facts rather than public statements, and designed to deter without provoking unnecessary escalation. Strategic persistence against Beijing. With more than four decades of service, a profound mid-life modernization, and a track record that ranges from humanitarian evacuations to high-intensity conflicts, Abraham Lincoln represents the material continuity of American naval strategy. His presence against China It does not respond to a specific crisis or a specific situation, but to a structural logic that defines the Indo-Pacific like a central theater for the United States. In a context of growing competition and transition of the international order, the underlying message is that Washington has no intention of withdrawing or giving up operational space, and that its naval power will continue to be a constant, visible and functional factor in the region for the coming years.

Russia has reminded the planet that the war in Ukraine is a ticking bomb. And for this he has pressed a nuclear button: Oreshnik

by

Over the past few months, the war in Ukraine has seemed advance by inertia: fronts that barely move, stalled negotiations and constant wear and tear that threatens with normalizing the conflict in Europe. But in recent weeks Moscow has remembered, without the need for major territorial conquests, that it continues to have the ability to alter the chessboard with a single gesture: the nuclear one. The button that is always there. In a stuck war In the mud of the front and industrial wear and tear, Russia has once again remembered that it is still sitting on a strategic bomb pressing a button that does not need to be pressed completely to take effect: that of Oreshnik missilean intermediate-range system with nuclear capacity whose use, even with inert or conventional charges, functions as a political message rather than as a tactical weapon. The launch detection from the Kapustin Yar strategic polygon and the subsequent explosions near Lviv, a few kilometers from the Polish border, do not seek so much to destroy decisive objectives as to point out that Moscow can escalate whenever it wants and from wherever it wants, even from facilities associated with its strategic nuclear forces, deliberately breaking the “conventional” routine of the conflict. Symbolic weapon, real threat. It we have counted before: the Oreshnik, derived from the RS-26 program and capable of carrying multiple warheads that separate in flight, it is not a missile designed to win battles in Ukraine, but to cross psychological red lines in Europe. Its hypersonic speed, its potential range of up to 5,500 kilometers and the fact that Ukraine lacks defenses capable of intercepting it turn each launch into a demonstration of the structural vulnerability of NATO’s eastern flank. When Russia first used it against Dnipro in 2024 with dummy heads, he made it clear that he was not testing marksmanship, but rather strategic credibility. Now, by bringing the impact closer to the NATO border and the European Union, the message is even more explicit. Controlled climbing. The reappearance of the Oreshnik is no coincidence. It occurs while Ukraine refuses to give up territory in the negotiations, while Moscow insists that any Western troops deployed on Ukrainian soil would be a legitimate objective and while Washington, under Trump, intensifies pressure on Russia’s allies like Venezuela. The Kremlin justifies the attacks as retaliation for alleged Ukrainian attempts to attack the residence of Vladimir Putinaccusations that even US intelligence services they doubtbut the real logic is different: to raise the psychological and political cost of Western support without formally crossing the nuclear threshold. Energy, winter and strategic terror. As in previous winters, Russian missiles and drones are once again baiting the Ukrainian energy infrastructureleaving entire neighborhoods in kyiv and other cities without electricity or heating amid sub-zero temperatures. The Oreshnik fits into this strategy of calculated terror: not only does it damage critical facilities, but it amplifies the feeling of helplessness by introducing a weapon that symbolizes the maximum possible escalation. Ukraine responds by hitting power grids in Russian regions such as Belgorod or Oryol, but the strategic asymmetry remains intact. Europe as a target audience. Furthermore, by hitting near Lviv and, by extension, Poland, Russia is not just talking to kyiv, but with Brussels, Berlin and Paris. The Oreshnik is a reminder that Ukrainian theater is inseparably linked to European security and that any expansion of military support has an immediate reflection on the deterrence ladder. It is no coincidence that Moscow recently showed the deployment of the system in Belarus, further extending the reach shadow over the continent. The temptation of blackmail. Thus, with minimal and extremely slow territorial advances, and a growing human and industrial cost, Russia uses the Oreshnik missile as a substitute for victories on the battlefield. It is not a weapon to conquer Ukraine, of course, but rather to remind the world that the conflict cannot be closed by ignoring the Russian nuclear dimension. From that prism, each launch is a warning: Moscow does not need to detonate a warhead to reactivate the founding fear of the Cold War. Just show the button, press it even half and make it clear that it is still there, waiting, like a time bomb that sets the pace of all future negotiations.

While Silicon Valley dreams of servers in orbit, Russia prepares a nuclear reactor on lunar soil

by

Until recently, the space race was about seeing who could get there first. Today, the question is different: who will be able to turn on the light on the Moon? While companies like Google or Nvidia imagine satellites loaded with computers for their Artificial Intelligence, Russia has hit the table with a much more earthly (or lunar) plan: installing a small nuclear power plant on the surface of our satellite. A reactor by 2036. The Russian space corporation, Roscosmos, has signed a state contract with the aerospace company NPO Lavochkin to develop a lunar nuclear power plant. According to Reutersthe deadline marked in the contract is 2036. However, the political times are much more aggressive: Yury Borisov, head of Roscosmos, has placed the real operational window between 2033 and 2035. Although official statements sometimes avoid the word “nuclear” directly, project participants dispel any doubts, the Kurchatov Institute (a leader in nuclear research in Russia) and Rosatom (the state atomic flagship company) are in charge. As the Interfax media points outthe objective is to power the infrastructure of the International Lunar Research Station (ILRS), a joint project with China that seeks to move from “round trip” missions to a permanent human presence. But why what nuclear? A colony on the Moon faces nights that last 14 Earth days. During that time, the frigid temperatures and lack of light make the solar panels useless to keep astronauts alive or power life support systems. Mikhail Kovalchuk, head of the Kurchatov Institute, he explained in an interview with the Russian agency TASS that Russia must “run forward.” According to this medium, the country seeks to consolidate its leadership through the “Atomic Project 2.0”, which includes new generation reactors and closed cycle systems. It’s not just about science; Russia admits that partners like China and India have learned a lot from them and are now direct competitors. Eyes in the sky: preparing the ground. For the Russian reactor to reach the Moon, Moscow is already preparing the logistics. According to another TASS statementRussia plans to launch 52 satellites from the Vostochny cosmodrome. Among them, the Aist-2T stands out, capable of creating 3D models of the lunar terrain and monitoring emergency situations. It is the necessary infrastructure so that the “lunar atom” does not suffer the same fate as the failed Luna-25 probe in 2023. The Moscow-Beijing axis: a long-range alliance. This deployment is not a solitary effort. As Interfax detailsRussia and China formalized their ambition in May 2024 with a memorandum of cooperation for the joint construction of this nuclear plant. They are not starting from scratch: both countries presented a roadmap in 2021 that includes five joint missions to deploy modules in lunar orbit and surface. While Russia brings its historical advantage in space nuclear facilities, China provides the scientific capacity and resources for the ILRS Station to be permanently inhabited from 2030. The board of the new Cold War. Washington has not stood idly by in the face of the Russian-Chinese alliance. NASA has received a clear directive from the current administration, in which they state that They need a reactor on the Moon by 2030. “We are in a race with China,” said Sean Duffy, Secretary of Transportation and who has led this directive. The background of this urgency is not only prestige, but the control of strategic resources. The Moon is the great deposit of Helium-3, an extremely rare isotope that is emerging as the “fuel of the future” for nuclear fusion. The White House’s fear is that if the alliance between Russia and China comes sooner, they will be able to declare “exclusion zones,” blocking access to this isotope and other essential metals for the technology industry. Faced with this threat, the US has increased the power of its nuclear project from the original 40 kW to a minimum power of 100 kW. Infrastructure over prestige. The space race of the 21st century has ceased to be a question of prestige and has become a question of infrastructure. While Big Tech tries to solve its energy limits with promises of servers in orbitRussia and China have opted for the pragmatism of the reactor on solid, but lunar, soil.

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. And Europe is already accelerating its production In Xataka | We have been believing that bacteria are a weapon against tumors for 150 years.

nuclear microreactors made like Lego pieces

by

The artificial intelligence revolution has an Achilles heel that is not in the code, but in the networks. In this scenario of “energy hunger”, an Austin company called Aalo Atomics has decided that the solution is not to wait for the State to build infrastructure, but to manufacture its own nuclear reactors like someone making Lego pieces. A unique structure. If decades ago the message “Hello World” marked the beginning of the computer age, today the “Aalo World” aims to mark the beginning of the Second Atomic Age. According to a company press releaseAalo Atomics has begun construction of an experimental reactor, the Aalo-X, under the Department of Energy’s (DOE) Nuclear Reactor Pilot Program. The ambition is such that, as reported by NucNetthe company has already shipped the first five test modules (the Aalo-0 prototype) from its factory in Austin to the Idaho National Laboratory (INL). The goal is to have everything ready by July 4, 2026. The “Bring Your Own Energy” model. AI data centers have sparked a new business fever: the “bring your own energy”. Giants like Microsoft, Google or Amazon can no longer depend on an American electrical grid that, although should add 80GW of capacity per year, barely reaches 65GW due to bureaucracy and bottlenecks. This is where the star product comes in: the Aalo Pod. According to the company’s technical informationit is not an eternal “construction project”, but rather a mass-produced product. Each “Pod” will generate 50 MW and is designed to be adjacent to data centers. By not requiring external water sources for cooling – thanks to their air condensers – these plants can be located in arid or remote areas, directly feeding the servers without going through the saturated electrical grid. “Lego” engineering. The key to Aalo Atomics’ success lies in three pillars: Products, not projects. According to Matt LoszakCEO of Aalo Atomics, the historical mistake of the sector was to build each plant as a single civil work. His XMR concept (Extra Modular Reactor) allows parts to arrive on site as finished and tested blocks, ready to be connected. Sodium technology. Unlike conventional plants, sodium allows the reactor operates at atmospheric pressure. This eliminates the need for expensive, gigantic containment domes. To avoid incidents like the one at the Monju plant (Japan) in 1995, Aalo Atomics has developed double-walled steam generators and an AI-powered autonomous maintenance robot that remotely detects and seals leaks. Passive security. The design, led by Yasir Arafat (CTO of Aalo Atomics), uses a fuel that expands naturally if the temperature rises too high, stopping the reaction by physical laws, without the need for human intervention. An extensive collaboration network. Dubbed the “Aaloverse”, it has woven an ecosystem of 127 suppliers in 35 states that transcends the energy sector to integrate the current kings of silicon. Microsoft and NVIDIA not only appear as potential clients, but as technological partners for the development of a “digital super operator”. This artificial intelligence platform, supported by NVIDIA’s computational muscle and Azure tools, seeks to automate the enormous bureaucracy of nuclear permits and manage the reactor with a minimal human workforce, turning the plant into an autonomous system capable of predicting failures before they occur. For this digital vision to be translated into real energy, Aalo Atomics has resorted to the reliability of traditional heavy industry, closing alliances with giants such as Baker Hughes and Siemens for the supply of turbines and generators. This strategy, together with a historic contract with Urenco, accelerates its arrival on the market and guarantees enriched uranium for the Aalo-X reactor in 2026, breaking dependence on foreign supplies and shielding the energy sovereignty of future data centers. Towards a Second Atomic Age? Aalo Atomics faces a challenge that the industry considered impossible: going from the founding of the company to nuclear fission in less than three years. However, with $136 million in financing and the first hardware already on Idaho soil, doubt is giving way to expectation. If they manage to turn on Aalo-X in the summer of 2026, they will not only have built a reactor; They will have inaugurated a model where nuclear energy is as modular, scalable and private as the servers themselves that today try to decipher the future of humanity. The race is on and, for now, Idaho’s clock is ticking. Image | Aalo Atomics Xataka | The boom in companies developing SMR reactors is no coincidence: it is just what the military wanted

When nuclear energy orbited the Earth. The day a Soviet satellite with a reactor fell in Canada and unleashed a crisis

by

In the late 1970s, the idea that a nuclear reactor could fall from space ceased to be science fiction and became a real problem on the table of several governments. A Soviet satellite with a reactor on board It had lost control and was heading towards the Earth’s atmosphere, without anyone being able to specify where its remains would end up or what consequences the impact would have. In the midst of the Cold War, secrecy and urgency marked decisions. From there, questions arose that remain uncomfortable today: what was a nuclear reactor doing in orbit, why that risk was accepted, and what happens when technology escapes the script. As CBC points outOn January 24, 1978, the Soviet satellite Kosmos-954 re-entered the Earth’s atmosphere after weeks of tracking by American radars. No one knew with certainty where he would fall or in what state his remains would reach the ground. Eventually, fragments of the device were scattered over a vast region of northern Canada, from the Northwest Territories to areas that are now part of Nunavut and northern Alberta and Saskatchewan. What began as an orbital control problem suddenly became an international emergency with scientific, diplomatic and health implications. The day the Cold War left radioactive remains over Canada Kosmos-954 was neither a scientific satellite nor an isolated experimental mission, but one more piece of a Soviet military system designed to monitor the oceans. It was part of the US-A series, designed to locate large ships, especially American aircraft carriers, using radar. To power this system, which is very demanding in terms of energy consumption, the Soviet Union resorted to a compact nuclear reactor, a solution that allowed operate for long periods without depending on solar panels. That technical choice explains why the satellite had fissile material on board and why its loss generated so much concern. The technological heart of Kosmos-954 was a BES-5 reactor, known as “Buk”, developed specifically for Soviet military satellites. This type of reactor used uranium-235 and was designed to power the US-A system radar for the life of the satellite. The BBC estimates that 31 devices were launched with BES-5 for this family of satellites, and places the use of reactors in space until the end of the 1980s, with launches that continued until 1988. That history was not a clean line, according to the BBC: there were previous failures and accidents, including serious problems in one of the first flights in 1970 and the fall of another reactor into the Pacific Ocean after a launcher failure in 1973, in addition to the plan security plan contemplated moving the core into a waste orbit to prevent its return to Earth. Arctic Operational Histories explains that The signs that something was wrong came weeks before re-entry. Tracking systems detected that Kosmos-954 was progressively losing altitude, an anomaly that indicated a serious failure in its orbital control. The United States began to follow its trajectory with special attentionaware that the satellite had a nuclear reactor on board. The big unknown was not only when it would fall, but whether the Soviet security system would manage to separate the core and send it to a safe orbit before the device entered the atmosphere. When it was confirmed that the debris had fallen on Canadian territory, the problem took on a completely new dimension. Authorities knew the fragments were scattered over a vast, largely remote, snow-covered region, making any quick assessment difficult. The first measurements detected radiation in some points, although without a clear map of the contamination. Faced with this uncertainty, Canada had to quickly decide how to protect the population and how to locate potentially hazardous materials in an extreme environment. To confront an unprecedented situation, Canada turned to international cooperation. Operation Morning Light mobilized Canadian and American military personnel, scientists and technicians, many of them from units specialized in nuclear emergencies. From improvised bases in the north, flights equipped with sensors capable of detecting radiation from the air were organized. Each anomalous signal led to more detailed inspections, in a race against time marked by extreme cold and lack of infrastructure. As the search continued, it became clear that the contamination was more complex than expected. Not only visible fragments of the satellite appeared, but also much smaller radioactive particles, difficult to detect and remove. This forced the teams to take extreme precautions expand tracking areas. At the same time, delicate communication work began with the northern communities, who wanted to know what real risks existed for health, water and the fauna on which they depended. As the weeks passed, the operation narrowed its objectives. The official Morning Light phase lasted 84 days, although CBC describes the search effort as extending through most of 1978 and the search covering an area of ​​124,000 square kilometers. In this process, 66 kilograms of remains were recovered and Canada considered the immediate threat to the population and the environment contained. The economic cost was raised and Ottawa claimed 6.1 million dollars from the Soviet Union, which in 1981 agreed to pay half, opening an unusual diplomatic process for an incident of this type. The case of Kosmos-954 was not closed with the removal of the remains from the ground. In the months since, the incident reached international forums and fueled an uncomfortable debate about the use of nuclear power in space. Several countries demanded greater security guarantees and more transparency in programs that, until then, had been developed under strong secrecy. The episode served to reinforce the idea that space accidents do not understand borders and that their consequences could directly affect third countries.

The US has joined the “party” of China, Russia and Japan in the Pacific: with its nuclear bombers

by

As if it were an air parade of an air force planetarythe sky of the Asia-Pacific has become a scene of military exhibitions that have rarely been seen outside of a major war conflict. It happens that these fireworks can lead with a single spark into something very different. The improvised aerial party. As we said, the sky of Asia is a tour de force where every time it hides lessand where you patrol, joint exercises and strategic flights function as political messages in broad daylight. Russia and China have been setting the pace with bombers and fighters over disputed seas, Japan responds by raising the profile of its air defense and, now, the United States has decided to join visibly to this choreography of power, incorporating its strategic bombers into a dynamic that reflects the extent to which the region has become one of the epicenters of global rivalry. Bombers Made in USA. The joint flight of two American B-52s with Japanese fighters over the Sea of ​​Japan represents a qualitative leap in the signal sent from Washington, not so much because of its technical novelty as because of its symbolic load. The presence of bombers capable of carry nuclear weapons escorted by Japanese F-35s and F-15s, publicly reinforces the idea that the alliance between both countries is not rhetorical, but operational, and that the United States is willing to support Tokyo with strategic assets at a time of maximum friction with Beijing. The background. This show of force does not arise in a vacuum, but in the midst of an accelerated deterioration of relations between China and Japan that we have been telling, fed by the statements from Prime Minister Sanae Takaichi on a possible conflict scenario around Taiwan. Beijing considers these words a direct provocation and has responded combining diplomatic pressure, economic threats and a notable increase in military activity near Japanese airspace and disputed islands, raising the risk of unwanted incidents. Russia enters the scene. The previous presence of russian bombers Flying alongside Chinese aircraft near Japan and South Korea adds an additional layer of complexity to the scenario, projecting an image of strategic coordination against US allies in the region. For Tokyo, these joint patrols are not routine exercises, but a clear sign of directed pressure, which explains why the Japanese response has involved reinforcing its coordination with Washington and unambiguously accept the presence of high-profile American assets. Washington balances muscle. Although the White House has tried to reduce the drama of these flights, pointing out that they were planned in advance, the regional context gives them meaning. hard to ignore. The United States tries to maintain a delicate balance: show military commitment to Japan and deter China without completely breaking the channels of dialogue with Beijing, especially at a time when Washington continues to seek commercial stability and avoid an open escalation in the Pacific. An increasingly charged sky. With fighters blocking radarsstrategic bombers crossing disputed seas and joint exercises Happening at an almost routine pace, the airspace of East Asia has become a board where each flight counts as a political statement. The explicit input of the United States in this aerial “party” confirms that the fight between China and Japan is no longer just bilateral, but a broader reflection of the competition between great powers, one in which bombers and fighters seem to speak louder (and clearer) than diplomatic communications.

Drones have reached France’s nuclear submarines

by

What began more or less a year ago in a hesitant way has become a certainty: Europe has entered a new phase hybrid confrontationone where traditional lines of defense become insufficient in the face of a range of tactics that combine cheap technology, covert actors and deliberate strategy to saturate to the states with ambiguous threats. The last barrier that has been jumped is, perhaps, the most dangerous. Disturbing mutation. The recent drone flyover on the nuclear submarine base of Île Longue, in France, and the immediate declaration a few hours ago of the state of emergency in Lithuania due to balloons from Belarus, these are not isolated incidents but manifestations of a growing pattern which seeks to explore vulnerabilities, overwhelm alert systems and expose the fragility of European security. Both episodes show the extent to which hybrid warfare has ceased to be an abstraction and has become an operational reality that affects civil aviation, nuclear infrastructure and political stability on the eastern border of the European Union. Drones on nuclear deterrence. That five drones of unknown origin managed to lurk over the weekend on Île Longue, the most sensitive installation of the French deterrence apparatus, marked a turning point. This base houses the four nuclear ballistic submarines of the French Navy, the core of the capability “second blow” of the country. The military response It was immediate: deployment of units, electronic counterattacks using jammers and activation of the alert protocol for strategic installations. It turns out that no drone was neutralized nor identified to its operators, which increases the feeling, once again, of a threat that operates deliberately in the dark. France had already registered similar raidsbut the temporal coincidence with others in Europe and the systematic use of drones near bases with nuclear weapons reinforce the suspicion that these maneuvers seek to test response times, map defensive patterns and, above all, generate a climate of concern both among military officials and the population. Extra ball. Although the French prosecutor’s office insists that there is no evidence of foreign interference, strategic context points to more than just random flights: from Ireland to Denmark, passing through the Netherlands and Germany, anonymous raids on airports, air bases and reinforced security zones have proliferated, many of them documented by military authorities that do not rule out the hand of Moscow. A vulnerability and pressure of airspace. He episode in Irelandwhere several military-style drones appeared in the air corridor planned for the landing of Ukrainian President Volodymyr Zelensky, raised even more alarm. The reason: Ireland lacks radars operational, it does not have solid protocols to classify aerial threats and has minimal capabilities to counter drones, a strategic void that was exposed in the face of a possible operation designed to highlight national weaknesses. On a continent where drones have already forced to close airports Repeatedly, the Irish incident fits into a sequence of actions that seek to demonstrate that any country, even one that is not militarily involved in the war, can be vulnerable. Irish experts they warn that, regardless of the authorship, the confusion generated and the inability to react clearly represent a victory for any actor seeking to erode European cohesion. An official inspects a balloon used to transport cigarettes, in an undated photo released by the Lithuanian State Border Guard Service Balloons from Belarus. In parallel, a few hours ago Lithuania was forced to declare the state of emergency due to the constant arrival of weather balloons from Belarus. At first glance, these devices seem harmless, mere carriers of contraband. But in logic of hybrid warfarewhat is important is not so much the sophistication of the medium but its ability to force a disproportionate state response. The balloons have invaded Lithuanian airspace, forcing to close repeatedly Vilnius airport and have introduced concrete risks for civil aviation, forcing authorities to mobilize civil, police and military resources. A war of attrition. For Lithuania, a country bordering both Belarus and the Russian enclave of Kaliningrad, these incidents are not perceived as minor events, but as part of an attrition strategy intended to saturate their surveillance capacity and underline their exposure. After months of drone incursions, cyberattacks and electronic warfare, Vilnius interprets balloons as another step in a calculated escalation that uses cheap means to obtain strategic effects. Signs and a more aggressive phase. If you also want, what connects drones on French nuclear submarines, unidentified devices over Ireland and smuggling balloons that force an entire country to activate a state of emergency is its strategic role: demonstrate that Europe can be destabilized with simple tools, difficult to attribute and capable of generating considerable psychological, economic and political costs. So far, each incident individually can be minimized, but together they paint a picture. simultaneous pressure map on European airspace, on critical infrastructure and on the institutional cohesion of the EU. France already speaks openly about a “hybrid confrontation”Denmark attributes some incidents to “hybrid threats” of probable Russian origin and the Baltic countries consider each action a destabilization test. The result is a Europe that recognize the dangerbut that is still far from a unified response capable of tackling a threat that thrives precisely on ambiguity, the proliferation of small incidents and the difficulty of proving direct responsibility. An unprecedented threshold. What does seem crystal clear is that these episodes as a whole reveal that Europe is crossing a threshold where conventional security is no longer enough. Russian hybrid warfare (or, at least, the widespread perception of its advance) is now manifesting itself in ways that disrupt civil lifecompromise nuclear assets and overwhelm state apparatuses where they are most vulnerable. The presence of drones on a base that houses the french nuclear deterrent and the need for Lithuania to activate extraordinary powers to stop improvised balloons are signs of the same trend: the adversary does not need spectacular victories to cause damage because it is enough to multiply ambiguous threats until stability is eroded. Perhaps that is why the big question has been on … Read more
