If Europe drums arrive, it will respond with a duplicate nuclear force

by

At the end of the 1950s, France, in the figure of Charles de Gaulle, promoted the idea that the nation could maintain some strategic dependence by launching the Nuclear deterrence policy Sovereign, a kind of nuclear umbrella arguing that, although the United States was an ally, its interests could Do not match Always with those of Europe. Half a century later, that idea sounds strongly in the old continent with an unpublished Anglo-French alliance. An unprecedented agreement. United Kingdom and France, the only two sovereign nuclear powers of Western Europe, have first announced the decision to coordinate the Use of its atomic arsenals in response to any extreme threat that endangers the safety of the continent. He agreementpresented by British Prime Minister Keir Starmer and French president Emmanuel Macron during a state visit to London, brand A significant turn In strategic cooperation between the two countries, especially in the face of the renewed fear of Russia’s aggressiveness and uncertainty about American commitment to European collective defense under Trump’s leadership. Asterisk. Very important; although the British and French arsenals will continue to be technically independentnow they can be used jointly in case of conflict, an unequivocal signal for both allies and adversaries that any serious aggression against one of the two will be answered by both. Differences overcome by a threat. The pact represents a symbolic overcoming of traditional differences between London and Paris in nuclear doctrine. United Kingdom has integrated its arsenal in the nuclear planning structure of NATO And it depends technically on missiles supplied by the United States, although it operates autonomously. France, on the contrary, has always defended with zeal Total sovereignty About his deterrence, refusing to participate in the NATO nuclear cast system, and maintaining An independent doctrine whose strategic scope (“vital interests with European dimension”) has been deliberately ambiguous. The decision to act coordination does not involve merging capabilities, but synchronizing potential responses and generating a unified front against possible aggressions, especially in a scenario of weakness in transatlantic commitment. Storm Shadow Complement and evolution. Both countries possess Comparatively small arsenals In relation to the great nuclear powers. United Kingdom bases its deterrence In Trident missiles launched from submarines, but has announced plans to incorporate an air capacity by F-35a aircraft of American origin capable of carrying nuclear weapons. France, on the other hand, maintains a completely national force, which combines maritime and aerial vectors. In addition, he works In the ASN4Ga next-generation hypersonic air-earth missile with nuclear capacity (which United Kingdom Study adopt), which would mean having for the first time in decades of an air nuclear system independent of American control. The new coordination will allow, among other options, synchronize underwater patrols or stepped maintenance periods to ensure a continuous presence in the sea. Experts such as Camille Grand and Lawrence Freedman highlighted the transcendence of the ad, since France He had never admitted Publicly no type of nuclear cooperation of this type, which implies an important doctrinal change. TRIDS DIAGRAM The American umbrella. He underlined The New York Times That the decision to move towards an incipient form of coordinated nuclear deterrence responds, in addition to the Russian threat, to the Strategic emptiness that has left Washington’s ambiguous attitude towards European defense. The traditional dependence of the NATO nuclear shield, under American leadership, has It was questioned for Trump’s skepticism regarding the usefulness of protecting the allies of the continent. In this context, Franco-British tandem assumes the responsibility of projecting a credible European alternativealigning their respective defensive doctrines and sending a clear message to Moscow about the consequences of continuing his offensive in Ukraine. The pact is articulated within a greater strategy to revitalize the call “Coalition of the willing”an informal alliance of European countries that seek to sustain the Ukrainian war effort before the American replication. Challenges: Ukraine and coalition. Plus: The agreement comes in a moment especially delicate In the Ukraine conflict, where the promise of a high fire driven by Washington has not been completed and Western military aid, especially from the United States, is He has slowed down. Starmer and Macron, which lead the hard core of the Pro-Ukrainian coalition, seek to recover the impulse through A virtual conference with other allied leaders from a military base on the outskirts of London. However, some countries continue showing reluctance To send material means such as combat airplanes, which underlines the difficulties in maintaining cohesion in a fragmented coalition for divergent interests and national agendas. The joint nuclear initiative is thus enrolled in a broader logic of diplomatic pressure to Hold the commitment European in the face of transatlantic umbrella. Friends after Brexit. The nuclear pact, in addition, symbolizes a significant thaw in the relationships between London and Paris, deteriorated after the referendum Brexit. Starmer and Macron have presented this relaunch of links as a stage of pragmatic understanding, cemented not only in collective safety, but also in thorny areas such as migration. Both governments negotiate A new agreement To stop migrants’ crosses in small boats from the coast of northern France, a growing problem that has generated bilateral tensions. The objective is to reduce flows without giving up humanitarian obligations, in the midst of growing political pressure by populist parties as reform uk. The Lancaster Pact. The Franco-British alliance also extends to the joint development of new conventional capacities. Within the framework of the so -called “Lancaster House 2.0”both powers will sign an update of the Defense Treaty signed in 2010. This new agreement provides for the creation of a new generation of long -range missiles that will replace the Successful Storm Shadow/Scalpused by Ukraine, in addition to an extension of the joint expeditionary force. Likewise, development is contemplated of Air-Aire missiles latest generation, microwave weapons to interfere with drones and missiles, electronic war systems and intensive artificial intelligence use To coordinate attacks with millimeter precision. These initiatives reinforce the projection capacity of both countries and consolidate their role as central safety guarantors in Europe, at a time … Read more

There is a single opportunity in 11,000 years of reaching the planet Sedna. Some Italians want to use this nuclear engine

by

A team of Italian scientists has drawn a plan to achieve one of the most distant and enigmatic objects of our solar system: the Dwarf Planet Sedna. Two options. Research, Prepublished in Arxivdetails two concepts of spacecraft to drastically shorten the trip to Sedna. Not only with the aim of doing so in less time, but also quick enough to arrive before the dwarf planet immerses itself in the dark of deep space for thousands of years. One of them is a high -tech solar candle that, according to researchers, could make the journey in just seven years. The other is a nuclear fusion rocket that would do it in about ten, but with a great advantage: it could enter orbit once there. The moment is key. He Planet Sednadiscovered in 2003, has an extremely eccentric orbit that lasts about 11,000 years. In 2076 he will reach his perihelio, the point of his orbit closest to the Sun, although “close” is a relative term: it will be almost 11,000 million kilometers, about three times the distance from Neptune to our star. It is a unique opportunity in millennia to send a probe. With current rocket technology, such a trip would require between 20 and 30 years, which would force to develop in record time an incredibly complex and high -budget mission. The cheap alternative. The first option is A solar candle that takes advantage of the thrust of the photons of the sun To propel the ship, a concept already tested in missions such as Lightsail 2 of planetary society. However, this candle would go one step further: it would be covered with a material that, when heated with sunlight, released molecules through a thermal disorption process that provided an additional thrust. Thanks to Jupiter’s gravitational assistance, this ultralight ship could reach SEDNA in just seven years. The great advantage is that it would not need to load with the weight of the fuel. The disadvantage is that I could only overflow, quickly through Sedna, As did the New Horizons probe with Pluto. I would collect valuable data, but the meeting would be brief. The ambitious alternative. The second proposal is more ambitious: a rocket driven by the direct fusion engine that is already being developed in the Plasma Physics Laboratory of Princeton University. This engine would not only generate thrust, but also electrical energy from a controlled nuclear fusion reaction, offering continuous and powerful acceleration. A trip with the nuclear engine would have been ten years. Although it is slower than the solar candle, it has a major prize: the ability to insert the ship into the Sedna orbit, making possible a much more detailed long -term study of its surface, its composition and its interaction with the space environment compared to the solar candle. Why Sedna? Not only because it is a transneptunian object, an ice cream that orbits beyond Neptune. Its reddish surface and its extreme orbit make it a pristine relic of the formation of the solar system. Scientists believe Sedna could contain organic compounds and water ice, the original “bricks” of the planets. Since most of its time passes far from the Sun, its surface has been protected from radiation and heat, being almost intact. One of the most fascinating hypotheses is that Sedna could be an exoplanet captured by our solar system during a stellar encounter in the past. Being able to analyze its in situ composition would literally study material from another star system without leaving ours.

China has already won the nuclear energy career to the US and Russia. And he has done it thanks to a avant -garde reactor

by

China’s nuclear program was born in the 50s of the last century. The cold war held by the US and the Soviet Union had incited these two countries to Develop your nuclear arsenal With a shocking speed, and Mao Zedong, the co -founder and leader of the Communist Party of China, decided to ask the Soviet Union for help for launch your own nuclear plan. In 1955 this cooperation allowed China to build its first floor of Uranium-235 and Plutonium productionand also supported the foundation of the National Nuclear Corporation of China (CNC). Only four years later, in 1959, the Soviet Union ended the collaboration with China in nuclear technology. This decision was a very hard setback for the country led by Mao Zedong, who embarked on A career towards self -sufficient in the development of nuclear energy. However, China’s plan prospered very slowly during the next three decades. The first nuclear power plant designed and built entirely by China, the Qinshan plant, was successfully connected to the electricity network on December 15, 1991. At that time China could not rival at all with The development of nuclear technology that had reached the US and the almost extinct Soviet Union. In 2002 China only had two nuclear centrals in operation. Today has no less than 58 nuclear reactors in activity. Only US has more (94). During the last two decades China’s civil and military nuclear program It has advanced with a vertiginous speed, but the most important thing is not the number of reactors that it currently has in operation: the really differential thing is that it has been placed At the forefront in nuclear technology. China leads thanks to its nuclear reactor of molten salts and Torio The TMSR-LF1 reactor officially entered into operation on October 11, 2023. A few months later, on June 17, 2024, he began working at full power. And on October 8 of last year the technicians who operate it detected protacinium-233 (PA-233), a radioactive isotope intermediate derived from the transformation of the thorium into Uranium-233 as part of the fuel cycle of the thorium. This nuclear reactor is in the Minqin industrial complex of the province of Gansu, in northern China. It has a power of 2 thermal megawatts (MWT), and, although it will not be the first Fourth Generation Nuclear Reactor in activity, and neither the first one that Torio will use as fuel, yes It will be the first of molten salts that will use this chemical element. However, the ambition of this Asian country does not end here; It is already planning to build a molten salts and torium reactor of more capacity for 2030, although China is not the only country that bets on this technology. China plans to build a molten salts and torio reactor of more capacity for 2030 The US, France or India are some of those who have also invested in research programs that pursue the development of nuclear reactors capable of generating electricity from the thorium. India’s in particular is interesting because it aims to demonstrate the viability of fuel cycles based on thorium in the context of its advanced heavy water reactor project. This technology is still far from being adopted in a generalized way, but its advantages closely link it to the future of nuclear energy. Our planet brings together approximately 12 million tons of thorium, so this chemical element is three times more abundant In the earth’s cortex that Uranium used as fuel in the current nuclear centrals. The largest deposits reside in China, Brazil, Canada, Australia, USA, Greenland, Russia, Norway, South Africa and Venezuela, although prospects reflect that the country that Torio has is precisely one of the ones that is investing most in the development of reactors capable of using it: India. Another point in your favor is that it is as easy to extract as uranium, but it has the inconvenience that it is not directly physable. It is necessary to introduce it into a reactor that manufactures uranium from Torio, and what it produces is not uranium-235, it is Uranium-233, but the important thing is that it is physable. Once this uranium has occurred, it can be introduced into a conventional reactor like those we have in Spain, which could not work with Torio, but with a derivative of that element. In addition, experts say that molten salts nuclear reactors are safer than reactors installed in the nuclear power plants that are currently in operation. Experts say that molten salts nuclear reactors are safer than reactors installed in the nuclear power plants that are currently in operation Two of the reasons are that they use as a refrigerant lithium fluoride and beryllium at a very low pressure, and the fuel remains dissolved in the form of salt, so it is very unlikely that an accident could trigger the fusion of the reactor’s core. Another quality of these reactors that are worth not overlooking is that Its architecture allows them to be installed undergroundwhich, again, increases your safety. But this is not all. Another peculiar and positive feature of these reactors is that they allow to recharge the fuel while remaining in operation. And, in addition, the fact that they do not need water to maintain the refrigerated nucleus allows them to be installed in regions in which water is scarce, or, simply, in areas where there is no river and are not close to the sea. This is one of the reasons why China is investing in the development of this technology as a means to build fourth generation nuclear power plants in the most remote and arid regions of the country. It is also worth not overlooking that Radioactive waste They generate have a much shorter semi -grid period than that of the residues of the reactors that use uranium, which logically facilitates their management. And, in addition, the folk salts reactors They use less fuel Because the efficiency of the thorium is much higher than … Read more

A US Nuclear Submarine has just arrived in Iceland for the first time in history. That can only mean one thing: Giuk

by

When 2025 United States began, a word incessantly repeated: Greenland. There was no appearance of Trump where he did not slide that Washington was interested in getting the small nation, even for the bad. Behind, of course, There was much more that an occurrence, because the island is part of a Western strategic edge that he shares with the United Kingdom and Iceland. Interestingly, the first nuclear submarine in the US has just come to stay. First nuclear scale. Yes, by first time In history, a nuclear propulsion submarine in the United States has docked in Iceland. He USS Newport Newsa fast attack unit Los Angeles classarrived in Reykiavik in a movement that underlines the growing strategic importance of the Arctic in a context of Geopolitical tensions increasingly acute. The Icelandic government only began to allow the entry of nuclear submarines in its territorial waters in 2023and this inaugural visit is part of an increasingly narrow cooperation pattern with Washington and NATO. The American navy presented the event as A “decisive moment” which reaffirms its commitment to collective defense and maritime security of the Arctic, while American diplomats in Reykiavik stressed that the operation has been carried out in full Coordination with Icelandcountry that does not have its own naval forces and depends on the allied umbrella for protection. Giuk. It We count A few months ago. The geostrategic background of the event is closely linked to the call Giuk runner (Between Greenland, Iceland and the United Kingdom), a strip of key waters through which routinely submarines of the Russian north fleet, including the advanced yasen-m Cruise missile carriers. The location of Iceland makes the island a vital control point to follow these vessels before they are hidden in the vast Atlantic and represent a potential threat to the east coast of the United States. During the cold war, Iceland housed to the 57th Hunting Wing of the American Air Force at the Keflavik base, as well as maritime surveillance detachments With P-3 Orion aircraft. Currently, this surveillance persists with modern P-8a Poseidon and with NATO fighters that rotate to cover the Icelandic airspace. The Newport News stop adds to that renewed defense network, in a context where NATO has intensified protection of underwater infrastructure after alleged sabotage acts Russian In the Baltic which alerted about the vulnerability of vital cables and conduits. Sobs on board the submarine make guard while arriving in Reykjavík, Iceland And more. As We explainYes, let’s say Russia or China cross the corridor, its location would become extremely difficult, both because of the acoustic conditions of the underwater terrain and by oceanic vastness. Thus, from those hidden positions they could launch missile attacks against objectives in the east of the American continent. In fact and in response to this, the United States formed in 2021 the so -called Task Group Greyhounda specialized group of anti -submarine destroyers Designed to counteract This specific threat. The American navy itself warned at the time that the east coast of the country already It was not a safe shelterunderlining the urgency of establishing surveillance and defense points in key areas such as Greenland. The Russian answer. The truth is that Russia has proven to know very well the value of this corridor. In 2019, he organized its greatest naval exercise From the Cold War, sending at least ten submarines through the completely submerged Giuk gap, with the aim of Reach the Atlantic without being intercepted. According to Norwegian mediathe intention was clear: to prove the capacity of the West to detect movements of his fleet and demonstrate that he could project power to the US coast. These exercises also fulfill a fund growing territorial presence. A new stage. Beyond its symbolic value, the arrival of the Newport News represents an important operational step for the United States: to have a logistic support point for nuclear submarines in the Arctic without the need for move to Scotland or northern Norway. The ship, equipped with twelve vertical launch tubes for Tomahawk missiles and anti -submarine and anti -surface warfare systems, also provides surveillance and deterrence in a region where Russia has reinforced its naval presence and has increased its military activity near Finland. Icelandic Foreign Ministry itself recognized that these visits contribute to continuous and efficient underwater surveillance that also protects critical infrastructures submerged in Icelandic waters. Since 2023, six American submarines They had already briefly entered the island waters for partial crew rotations, but this is the first stop in port, product of bilateral regulations prepared with discretion and based on similar agreements with other Nordic countries. An emerging axis. The submarine scale is not an isolated case: in 2019, B-2 Spirit poachers They also used Iceland as an advanced base, which was a novelty for both aircraft and for the island. The ability to operate from austere locations has become a key principle of the American projection strategy. Iceland, who for decades played a secondary role after the end of the cold war, is repositioning as a central node in the defensive device of NATO in the north, especially in front of the resurgence of the Russian underwater threat. This scale, therefore, is not only a naval operation, but a silent but unequivocal statement of intentions: the United States contemplates the Arctic as a theater of strategic competence in full boom, already Iceland as its new bastion.

China is building the fusion-fission reactor that the US canceled decades ago. The future of nuclear energy depends on your fate

by

In the newly built Yoohu scientific island, next to the city of Nancheng, China advances discreetly in its plans to materialize a project that the United States explored and abandoned decades ago: the hybrid fusion-fission reactor. Xinghou-1. His name means “spark”, and is inspired by an appointment by Mao Zedong: “A single spark can set the entire meadow.” But it’s no small thing: it has behind An investment of more than 200,000 million yuanthe equivalent of 28,000 million dollars. The objective: build a hybrid central with 100 megawatts of electrical power, 300 megawatts of thermal power and, most importantly, a plasma energy gain factor (Q) greater than 30. An unprecedented achievement that could redefine the future of nuclear fusion nuclear energy. What all this means. To understand the magnitude of this objective, you have to put it in context. The nuclear fusion, the same process that feeds the stars, promises clean energy without the radioactive waste of current nuclear fission. The great challenge is get a fusion reaction to generate more energy of which consumes. The National Ignition Facility of the United States achieved in 2022 a historical milestone with a value q of 1.5demonstrating for the first time a net energy gain. The International Experimental Thermonuclear Reactor (Iter), a gigantic multinational project that is being built in France, aspires to achieve a Q> 10 to demonstrate the viability of large -scale fusion. Xinghuo, however, points to a Q> 30, the threshold that experts consider necessary for a merger plant to be commercially profitable. How does China plan to make this giant leap? The answer is in your hybrid approach. A fusion-fission reactor. That is, a reactor that uses the high energy neutrons generated by a fusion reaction (the “spark”) to bombard a mantle of fistible material such as uranium. This triggers a fission reaction that greatly multiplies energy production. In essence, use the fusion as a catalyst to make the fission much more efficient. The Xinghuo-1 project has already entered into the initial phase, which includes the tender and evaluation of its environmental impact. Its development is in charge of the state company Nuclear China Industry 23 Construction Corporation (CNI-23) and the private company Lianovation Superconductor. The road that the United States abandoned. The concept is not new. During the 1970s and 1980s, the United States Department of Energy investigated hybrid reactors before political priorities changed. Concerns about nuclear proliferation (hybrids can be used to produce plutonium) and a strategic commitment to “pure fusion” such as the definitive and cleaner solution led to the abandonment of this line of research. United States, and with it much of the West, They put all their chips on projects like the iter. China, on the other hand, has seen a shortcut in the hybrid model. While pure fusion follows decades away from its commercialization, a hybrid reactor like Xinghuo could connect a merger plant to the electricity grid much earlier. As soon as in 2030, According to SCMP. A coordinated national commitment. Xinghuo is part of a well -financed fusion ecosystem. China also maintains the East project, a Tokamak fusion reactor that has been able to maintain a 100 million degrees plasma for more than 17 minutes. The Huanliu-3 project, a newer and more powerful tokamak in experimentation phase. And the CFETR project, A large -scale pure fusion reactorconsidered the Chinese equivalent of Iter. The success of Xinghuo not only depends on its own advances, but also on the development of a complex industrial supply chain for key components such as superconductor magnets and the thermal vacuum chamber. If China makes Xinghuo work, either in 2030 or 2035, the implications would be seismic. They would demonstrate the viability of a route to commercial fusion energy that the rest of the world abandoned long ago. He could put Beijing years, if not decades, ahead in the energy race.

In 1950 two scientists wondered if possible a nuclear bomb of 10 gigatons. Its results are hidden locked up

by

On October 30, 1961, a Soviet bomber furrowed the skies of the Arctic towards Novaya Zemlya. Under his fuselage he hung an artifact the size of a bus: an unprecedented nuclear pump. At 11:32, the called TSAR pump He released. A parachute slowed its fall, allowing the plane to move away. Then, a detonation illuminated the sky with a fireball of almost 10 kilometers in diameter and a fungus -shaped cloud that amounted to more than 65 kilometers. The show was surreal: the pump, With 50 megatones explosive (more than 3,300 times that of Hiroshima), became a symbol of the Nuclear madness. But it could be much worse. The awakening of a new era. With the atomic bombardment of Hiroshima and Nagasaki In August 1945, the world changed irreversibly. Those bombs, 16 and 21 kilotons respectively, they marked the beginning of the destructive power without a paragon of Nuclear weapons. However, despite their fearsome capacity, these weapons were only the first step towards a much more sinister technological escalation. What would later transcend the most reckless imagination. The most powerful pump ever detonated would be That Soviet tsar of 50 megatones, although designed to reach 100. However, the most disturbing thing is that this was not the summit. In hidden, the United States had still planned More huge. The “Super” concept. Hiroshima and Nagasaki bombs were based In fission: A chain reaction in which heavy nuclei are divided releasing energy. But as we said, in parallel to their development, some scientists imagined a second stage: The fusion. This implied union of light nuclei (as deuterium and tritium) to form a heavier one, releasing even more energy. It happens that this reaction required an initial fission explosion to activate, which would give rise to the concept of the Hydrogen pumps. In the 1940s they were just a theoretical speculation … but everything changed very soon. Photograph of a replica of the tarum pump housing Communism comes. After the detonation of the First atomic bomb Soviet in 1949, the United States accelerated its thermonuclear programs. The fear of communism, enhanced by the revolution in China that same year, made the National Security Council recommend quadruply military spending. In that context, the figures of Edward Teller and Stanislaw Ulam appear, who devised The design that even today supports the H bombs. In 1952, the “Mike” test of Operation IVY demonstrated for the first time the Thermonuclear principle: an explosion of 10.4 megatones (500 times Nagasaki) that left a crater of 1,900 meters wide. Despite such force, that was not enough for Teller. The Soundy germ. Two years later, in 1954, the so -called “Shrimp” bomb during the Castle Bravo test. A powerful explosion was expected, but the result of 15 megatons (1,000 times Hiroshima) even surprised its designers, both by strength and by the devastating level of radiation released. However, Teller’s impetus did not stop there either. I wanted more, Much more. It was then that one of the most delusional and terrifying projects of nuclear history emerged: the Sundial Project. Designed by Teller and his colleagues from the Livermore Radiation Laboratory, the plan proposed a new destruction scale: no already kilotons or megatones, we entered In the gigatons. A couple of brothers. They were designed Two weapons: Gnomon and Sindial. Gnomon would act as “primary”, with a detonation of 1,000 megatons aimed at detonating Soundy, which would reach a power of 10,000 megatons, that is, 10 gigatons. For placing it in perspective, he thinks again The image of the beginning. Well, the figure exceeds 200 times the tsar bomb, and almost does not fit in the conceptual framework of the physics of conventional explosions. The potential apocalypse. The logic behind Sindial overflows any traditional calculation. To such powers, the laws of escalation of destruction They lose any validity: The heat, pressure and energy released would be so monstrous that, a priori, they would open a hole in the atmosphere. In fact, A report Del Bulletin of the Atomic Scientists pointed out that a pump like a sundial, detonated about 45 kilometers of altitude, could cause fires in an area of the size of France. The death toll would be unthinkable, not only because of the immediate explosion but by global radioactive sequels. Hiroshima, with 140,000 victims, would be a sigh against cataclysm that would represent Sindial. It was not science fiction. Although it might seem like a laboratory fantasy, the Sundial Project It was not a joke or an eccentric occurrence. Declassified documents and historical analysis indicate that Livermore’s team worked seriously For years in the development of Gnomon, with concrete plans to test it in the Redwing operation of 1956. That test was canceled, but the mere existence of the plan shows to what extent the fear, scientific ambition and deterrence had pushed the superpowers to border the abyss of the unacceptable. Echoes of Sindial. Suindial never materialized, but his mere conception forced A critical reflection In American politics. The growing destructive power of these weapons overflowed not only military strategy, but also ethics, logistics and land physics itself. While many ruled out their tactical utility for being impracticable (a pump of such dimensions was impossible to launch), its potential as an instrument of symbolic terror was enormous. As with The TSAR pumpits value was more political than operational: a floating threat that showed how far a nation could go if I wanted. Monster in the shadows. Finally, the Soundal project is It was diluting between political restrictions, international treaties and practical sense (without serving as precedent). The Ratification of the treaty Partial prohibition of nuclear trials in 1963 was a brake on atmospheric tests, which in practice made it impossible to continue advancing in the development of extreme performance weapons. The strategy then went on to favor smaller, portable and operational multiple eyelets, leaving behind the vision of total apocalypse that represented Sindial and its cousin Soviet sister. Imagine the unimaginable. What’s doubt, today sundial is just a footer … Read more

His response was the largest underground nuclear base on the planet

Talking about the cold war is talking about espionage, secret bases, Advanced weapons to win the opponent in a potential armed conflict and, above all, the Atomic Arsenal Explosion And constant fear of Nuclear Apocalypse. And this implies talking about Russia and the US as protagonists, leaving us in the inkwell to other actors in the conflict. China was another proper name during the Cold War, getting fully into the nuclear race. And they did it big. With the world’s largest nuclear military plant, the mysterious nuclear military plant 816. Bad crumbs with the USSR. The cold war was a tremendously complicated conflict that was played three bands part of time. The US and the USSR were two of the legs, but China entered Liza when the Sino-Soviet conflict. Simplifying history, the Soviet Union And China competed for being the champions of communism and, at a time of 1969, the Soviet Union even considered bombing China with nuclear bombs, including Beijing. However, United States “intervened“, Turning the conflict and relations with China. The position of both approached the subsequent years, but before that, and with a China smelling that the USSR could threaten with its nuclear arsenal, began to build the Nuclear Military Plant 816. Great Nuclear Wall. Zhou enlaiChinese prime minister at that time, he responded to the Sino-Soviet rupture giving the Output gun to a military base in the Chongqing region that would be much more than a bunker: it would become the Nuclear underground installation most important in the country. The goal? Produce plutonium that could be installed in arms, creating nuclear missiles without Soviet help. The works began in 1966 and in process more than 60,000 soldiers of the popular liberation army participated. The objective of the installation was that he was armored against missile attacks, but also against earthquakes of magnitude 8. In addition, he had a great natural wall around him: the Jinzi mountain and his granite. Colossal. Secretism was a constant when building the complex. This is something common and logical in this type of facilities, reaching the extreme that the workers of the workers did not know what their relatives were working or where. In the official records it is indicated that 76 people died during some works that extended over 17 years, but there are sources They point out that the figure would be much greater. Apart, the nuclear military plant 816 has an area of ​​more than 104,000 m² and is the largest tunnel system excavated by the human being. Its 130 galleries total more than 20 kilometers long over 18 United Artificial Cuevas, has more than 13 levels and the height to the deepest point is almost 80 meters, similar to a 25 -story building. In addition, to go from some sites to others inside the plant, cars that circulated on underground roads could be used. That is … it’s huge The control table The reactor room Reverse. During the years of construction, China made Advances in its nuclear program. Although it has been more recent when they officially reached The 500 headsthe first public nuclear test in the country was in 1964, but the complex of the 816 Pedish served little. The reason? After 17 years building that colossal cavernary system and with the advances at 85%, they decided to cancel it. The changes in international relations and the dimensioning tension of the cold war led to a brake on the project. The reactor was never operational and the program was classified in 1984. In 2002, however, it came to light and we could know all these details, even knowing that part of the plant was recycled to become In a fertilizer factory. Tourists, welcome. But with all that excavated, it would be nonsense to have it closed to lime and song. Something like that must have thought of authorities, since, in 2010, they decided open part of the base to the public. Thanks to this we can see photographs like those that accompany these lines and know How would the conditions of a base destined to manufacture nuclear missiles in China 60 years ago. And, in addition to serving as a museum, it is a memorial for the human sacrifices of those who participated in the project, they were official … or those that do not appear in the records.

In the mid -twentieth century the nuclear was fashionable. So someone created “atomic” tomatoes and cucumbers

The human being has from the dawn of agriculture trying to improve their crops. Before the arrival of advanced laboratory techniques such as CRISPR or the tools that the transgenics gave them, our species tested with a retahíla of various strategies to obtain larger fruits and vegetablestastier or more resistant. Some more successful than others. Some that bordered the demential. To the latter group belongs to the atomic horticulture, Atomic Gardening. The name of the technique speaks for itself. Atomic horticulture started from the idea of ​​bombarding radiation plantations. The objective of atomic horticulture, or at least the nominal objective of this, was to force mutations that improve the properties of food that were extracted from them. For this, the orchards were arranged in concentric circles, in whose center the radioactive material was located (Generally cobalt-60) capable of emitting gamma rays. The disposition implied that the successive circles received radiation dose that could vary significantly. The closest plants ended up burned by radiation and many nearby developed lethal problems such as tumors. The rest of the plants would receive more moderate doses that would introduce small mutations in their DNA. These mutations could be harmful or beneficial: the technique could Accelerate the natural process Of genetic modification, the selection, natural or human, would make the rest. The origin of this practice is found in the first years of the nuclear era, in the 1950s. Behind this initiative could find an association called The Atomic Gardening Societydedicated to promoting this striking practice. In An article Posted in 1962 the magazine Naturethis agrarian society was defined as “a scientific, educational and non -profit body, which carries out research in plants reproduction using radiative and chemically treated seeds and plants.” The different members of the association could exchange through this different seeds and the organization also served to record the different genetic variations introduced into the plants. The Atomic Gardening Society He also published his own magazine in which members could share their experiences and knowledge. We pointed out before the objective of this practice was to improve the qualities of plants and their fruits, make the most productive and resistant crops and their most nutritious or tasty crops. However behind this practice there was something else: marketing. The 50s was the era of initiative Atoms for peacein whose bosom the atomic gardens were born. This initiative intended to show that the energy responsible for devastation in Hiroshima and Nagasaki could also be used for economic improvement, in this case, agricultural improvement. Atomic horticulture in Spain Atomic horticulture was not an exclusive idea of ​​great nuclear powers such as the United States or the Soviet Union but also various countries from Europe to Japan developed their own gardens. Spain also had Your own atomic garden. The so -called Atomic Jarín of Alcalá is what remains of the Spanish tante in this nuclear agriculture, the then called El Encín Gamma Radiation Field. The origin of this experiment, which did not use Cobalt-60 but Cesio-137is in 1959, when Spain began to leave its isolationist period and could receive this radioactive isotope from US nuclear power plants for the exotic objective of building its own atomic garden not far from the capital. Today atomic horticulture is history. As we pointed at the beginning, today we had less quirky techniques to introduce mutations into plants. The transgenic foods, despite all the controversy they generate, have been accompanying us for decades. In fact, the development of the “scissors” of CRISPR genetic edition has given a new push to the genetic edition of organisms. This tool allows a control never seen before, notably facilitating The work of those looking for Improve the quality, quantity or resistance of crops. Atomic horticulture is history, but their results still endure. They do it in the form of variants of fruits, vegetables and even ornamental plants whose origin is in one of the most unique agricultural practices in the history of humanity.

Israel has been bombing the nuclear facilities that build other countries around its surroundings. This is the real risk of collapse

by

On February 28, 2022, just four days after the start of The Russian Invasion of Ukrainethe country’s troops led by Vladimir Putin bombarded the vicinity of The Zaporiyia nuclear power plantlocated in the southeast of the country. Shortly after, during the night of March 3 to 4, the Ukrainian and Russian soldiers They fought together with the buildings of this nuclear installation. This scenario has been repeated several times since then, which has represented at some times a threat to the integrity of the nuclear reactors of this central. Unfortunately, the Ukraine War is not the only war conflict that has endangered one or more nuclear facilities. During the last five decades Israel has repeatedly bombarded Iraq nuclear plants, Syria and Iran with the purpose, according to the Israeli government, to prevent these countries from developing nuclear weapons. This is the same scenario as presumably triggered The last episode of the conflict between Israel and Iran on June 13. However, not all nuclear facilities are the same. Israel and the US argue that the plants of Fordo, Isfahán and Natanz, all in Iran, who have recently bombarded several thousand Uranium centrifugers. These machines contain uranium hexafluoruro (UF₆) inside, a corrosive gas that if it came to filter to the environment could trigger a radiological and chemical emergency, although there would be no nuclear explosion. In any case, in this article we propose to explore what would happen if one missile or other large -capacity projectile impact on the building of a nuclear reactor. Nuclear reactors cannot explode as an atomic bomb Nuclear centrals in operation used by many countries to generate electricity have been designed to offer A very high security level and hold your operation over time. The first protection barrier that nuclear reactors have external threats is the containment enclosure. This concrete structure is watertight and is designed to keep the primary circuit of the environment completely isolated (we will immediately see what this circuit consists of). This framework is designed not to be degraded by dilation, to support the energy of an earthquake, and even to resist very important collisions, such as the impact of an airplane. However, in addition to protecting the nuclear reactor from external aggressions, it is responsible for preventing the radioactive material to be lodged in the primary circuit Remove and get in touch with the atmosphere. Anyway, the first thing that a missile or a pump would have to damage to damage a nuclear reactor is to destroy, or, at least, penetrate the containment enclosure. The containment enclosure is designed to withstand very important collisions, such as the impact of a plane The other element of the installation that has a crucial role in the proper functioning of a nuclear reactor is the cooling circuit. Although, in reality, a nuclear reactor works side by side with three different circuits. The primary circuit consists of the vessel, which is the deposit that contains Fuel bars and the water that must remain in contact with them to absorb their thermal energy; For the heat exchanger, which is a second tank to which the hot water comes from the vessel; and by a pump that facilitates the circulation of water between the vessel and the heat exchanger. The primary circuit must be closed because the water it contains being in direct contact with the fuel bars is contaminated. And therefore, It is radioactive. The heat exchanger acts as a steam generatorso a second circuit is responsible for introducing the cold water inside that when it comes into contact with the hot water of the primary circuit, it enters the boiling. From there the necessary steam proceeds to transfer to the turbine the kinetic energy that will make it possible to obtain electricity thanks to the action of the alternator. Once the fluid crosses the turbine the water vapor cools and condenses inside an additional tank to promote the appearance of water in a liquid state that will be introduced again in the heat exchanger, thus giving rise to a second closed circuit known as secondary circuit. Again a pump is responsible for the water to circulate between the condensation tank and the heat exchanger. So far we have described two different closed circuits, the primary and the secondary, but we have left a loose end. In order for the water vapor of the secondary circuit to be condensed inside the condensation tank it is necessary to introduce in the latter cold water. And to do so it is necessary to resort to a third circuit known as cooling circuit. The water of this last installation comes from the sea or from a river near the nuclear power plant, hence it is necessary to accommodate this type of centrals near one of these two natural resources. The thermal energy exchange that occurs between these circuits allows us to obtain the electrical energy we need, which is the ultimate goal of nuclear power plants, but also seeks to keep the fuel bars housed in the reactor core within its optimal range of working temperature. The most serious scenario implies the fusion of the reactor core If the thermal energy generated by the fuel material of the fuel bars as a result of the sustained fission over time exceeds, for whatever reason, the capacity of the refrigeration systems of transporting that energy and maintaining the core of the reactor within the optimal range of working temperature, the fuel could be degraded. And if this happens, it could happen from the solid state in which it is initially to the semi -solid state, or even a liquid state. This phenomenon is known as the fusion of the nucleus, and can cause a part of the radioactive material to end up coming out of the vessel. This was, in broad strokes and without entering the causes of the accident, which happened In Chernobil reactor 4 In 1986, but There are very important differences between the nuclear power plant that … Read more

The US attack on Iran was a forceful message to the development of nuclear weapons. Less for North Korea

by

It is very possible that a nation has been stuck to television by observing everything that happened in Iran. About 20 years ago, North Korea began Send engineers Specialized in the excavation of deep tunnels to Tehran. Two decades later, what was learned was tested through the greater furtive attack of the United States against Iranian underground nuclear facilities. A nuclear lesson. They had several analysts In the CNN than the recent ones United States bombings by deployment of b-2 bombersThey have caused an immediate shock not only in the Middle East, but also in Eastern Asia. For experts, this act of force launches a clear (and dangerous) message to North Korea: without nuclear weapons, You are vulnerable. For Kim Jong Un, which has been reinforcing for years Your atomic program As the Central Survival Pilar of the regime, the US attack confirms a long sustained narrative: nuclear deterrence is the only reliable shield against a regime change from the outside. Thus, far from determining proliferation, military action against Iran could accelerate Pyongyang’s arms expansion, in addition to strengthening its Strategic Alliance With Russia, which has become A military lifeguardtechnological and vital economy For the North Korean regime since the beginning of the war in Ukraine. The Moscow-Pyongyang axis. We have gone counting. Since 2024, North Korea and Russia have Institutionalized your cooperation in a strategic agreement of broad scope. According to A report of the multilateral sanctions monitoring team, Pyongyang has sent More than 14,000 soldiers and millions of ammunition, including missiles and rockets, to support the Russian invasion of Ukraine. In return, has received Air defense systems, anti -aircraft missiles, electronic warfters, critical military technology and refined fuel. Plus: the ability to Build Shaheds. This exchange not only finances the North Korean military program, but allows you to access to advanced technologiesdirect experience in modern war and an alternative source of resources to Western sanctions. In the eyes of the North Korean regime, the pact is not only pragmatic but necessary in the face of international isolation, and the attack on Iran makes it even more indispensable. Examples feeding the paranoia. From that perspective, the strategic message could not be clearer to Kim: countries that do not have nuclear weapons are exposed to American intervention. Iraq was invaded without having weapons of mass destruction. Libya left his nuclear program in exchange for diplomatic normalization, just to see Gaddafi overthrown years later. Iran signed the nuclear agreement and maintained its enrichment below the arms threshold, According to the OIEAbut it was still attacked. Two certainties. In contrast, North Korea has already done Six nuclear testshe owns between 40 and 50 active heads and has developed ballistic missiles Intercontinental capable of reaching the United States. Its arsenal, which includes multiple launch vectors, makes Pyongyang an actor with real deterrence and radically differentiates it from Iran. For Victor Cha, from CSIS, American bombings to Iran reinforce in Kim two certainties: The United States does not have a viable military option against the North Korean nuclear program, and its decision to maintain and expand its nuclear arsenal was correct. First nuclear submarine of North Korea Tripartite deterrence. In addition, there is a difference against Iran: North Korea has a Triple Defense System that complicates any American military option. First, its own nuclear arsenal, second, the defensive alliance with Russia, which allows Moscow to intervene automatically in case of attack, and third, the legal and political need of Prior consultation With South Korea, required by the bilateral treaty with Washington, which converts any action into a regional and diplomatic high voltage issue. In this regard, Professor Lim Eul-Chul warnedfrom the Kyungam University, which attacking North Korea could detonate a Total nuclear wargiven your ability to respond. “It’s not Iran,” LEIF-AMER EASLEY emphasizesby Ewha Womans University. Pyongyang can Attack directly To the United States and, in addition, Seoul is shot from most of its weapons systems. Deterrence when rearma. The foreseeable consequence of the attack on Iran is a hardening of the North Korean position. The regime could Accelerate your tests Ballistics, advance in new eyes, experiment with long -range propulsion and expand your attack vectors. I would also do it under the mantle Russia protector and in open indifference to the resolutions of the UN Security Council, whose coercive effects have been reduced to a diplomatic formality. In strategic terms, North Korea’s reaction will probably not be defensive but expansive: Technological cooperation with Moscow, joint military exercises, transfer of ballistic knowledge and new forms of economic and military interdependence. The TNP. They remembered In The Conversation That the non -proliferation treaty, adopted in 1968, was a commitment between the five recognized nuclear powers (United States, Soviet Union, France, United Kingdom and China) to not transfer nuclear weapons and commit, at least formally, to disarmament. In return, other countries promised not to develop atomic weapons. The treaty, then reinforced with the additional protocol of the OIEA, endowed the nuclear inspection agency for broad powers for Verify peaceful use of atomic energy. It was the Oiea who first warned in 2003 about the suspicious enrichment of Uranium in Iran. And it was also this organization that, weeks before the recent bombings, denounced the Iranian breach for the first time in twenty years. A fragile pact. However, effectiveness of the TNP It has been undermined for decades. The nuclear powers never fulfilled their disarmament commitments. In the case of North Korea, He withdrew from the treaty In 2003, he performed his first nuclear test in 2006 and today could possess up to 50 eyelets. Israel, meanwhile, never formally joined, and maintains a unpacked arsenal. India, Pakistan and North Korea have stayed out or have been disconnected. In other words, the covenant has weakened by its own architecture that, although universal, is structurally vulnerable. Iran and North Korea. To all this, the professor of economics underlined Anthony Burke that Iran now has Two roads. The first would be to reconstruct its uranium enrichment capacity and acquire … Read more
