activates 10 new reactors and reinforces its nuclear domain

The tariff war between the United States and China has not caused the Asian giant to make hasty decisions. On the contrary, the Nation of Xi Jinping continues to work on plans in the very long term, as is the case of the silent boom of oil. In this race towards energy self -sufficiency, the nuclear sector is another of the points where the Asian country is advancing leaps. Short. China has approved the construction of 10 new nuclear reactors, in an investment that exceeds 200 billion yuan (about 26 billion euros), According to The Paper. In this way, China celebrates its fourth consecutive year giving green light to large -scale nuclear initiatives. Renewed impulse. This ambition by the Asian giant in the nuclear ecosystem will be in charge of three state companies: China General Nuclear Power Corp. (CGN), China National Nuclear Corp. (CNNC) and State Power Investment Corp. According to China Dailythe authorities have hardened the control measures to ensure that each new reactor complies with the security standards of the International Atomic Energy Agency (OIEA). State investment. The Chinese strategy is deeply linked to the optimization of construction and operation costs, thanks to the intervention of a state apparatus that facilitates loans with low interest rates, which has proven to be key to the viability of nuclear projects, such as has pointed out The Paper. Face to the future. The forecasts collected by Bloomberg They point out that China’s operational nuclear capacity will reach 110 million kilowatts by 2030, surpassing any other country. If you maintain this rhythm, by 2040 its nuclear park could touch the 200 gigawatts, which would be equivalent to about 10 % of all national energy production. The expansion. The nuclear advance of the Asian country is a strategic play, since in a global context towards cleaner sources, China seeks to position itself as an exporter of nuclear technology, including the own design reactor Hualong One. If this trend was consolidated, the country would be outlined as a geopolitical reference in the new energy order, combining industrial capacity, state financing and energy diplomacy to challenge Western hegemony.

Two workers from Elon Musk in Doge agreed to a private network. The US keeps the secrets of your nuclear arsenal there

In February, one of the most rocambolesque stories was known around Doge, the Government Efficiency Department led by Elon Musk to essence, cut where he can in the administration of the United States Government. Apparently, they fired 350 officials who had to Readmit rapidly. The reason: they were the specialists in the assembly of nuclear eyelets. The story has now taken a more dangerous turn. The access they should never have. I told it a few hours ago exclusively NPR through confidential information access. Apparently, it was revealed that two young employees of that government efficiency department (Doge) created under the orders of Elon Musk, obtained accounts in classified networks With nuclear information highly sensitive. What’s doubt, the news has unleashed a political storm and national security in the United States. Luke Farritor, a former 23 -year -old Spacex fellow, and Adam Ramada, a Angel Investor Without previous experience in armament or intelligence, they appeared for at least two weeks in the directories of the reserved systems of the National Nuclear Safety Administration (NNSA) and the Department of Defense, according to sources with direct access to the networks. From denial to confirmation. The media counted that, although the energy department first denied any link, later admitted that the accounts Yes they were createdalthough they insisted that never They were activated nor used. So, the medium NPR remembers that the mere existence of these accounts, in maximum security environments that normally require a “Q” accreditation (The highest level of authorization of the DOE), has aroused alarm among experts, who interpret it as a sign of the growing and worrying doge penetration in critical areas of the state apparatus. All nuclear information. To understand the importance of the network to which they have had access, let’s think that the systems accessed by these employees are not mere confidential data repositories: these are networks that store and transmit plans for nuclear weapons design, special materials for their manufacture and strategic communications between laboratories, production centers and the pentagon. The first one, the NNSA Enterprise Secure Networkserves to share Restricted data between key actors of nuclear arsenal. The second, Siprnetallows the flow of information classified between the Department of Energy and Defense, including operations that could compromise national security if they were disclosed. Although it appears in the access directories does not equals to directly see classified documents (by the policy of “Need To Know”), experts Consulted by NPR They emphasize that it is the technical “head” that could provide future applications or expand the scope of influence within those platforms. Shadows on transparency. Plus: the incident adds to a series of controversial episodes starred By Doge In other federal agencies. As we count in February, a purge in the NSA directed by Doge (reviring only partially after public pressure) caused the dismissal of dozens of nuclear area employees. Shortly after, an informant denounced that Doge members had accessed internal systems of the National Board of Labor Relations (NLRB), requesting that They will not register their activities and deactivating monitoring tools, in addition to delete access traces. Not just that. One of the income attempts was made from an IP address located in Russia Using credentials created by Doge, which unleashed new suspicions and ignited cybersecurity alerts in several sectors of the government. These movements, added to the recent scandal by the use of signal application On the part of the Secretary of Defense Pete Hegseth to discuss sensitive military operations, they delineate a dangerous informality pattern and reckless management of critical information of the nation. The Doge experiment. Thus, the very existence of Doge, an entity born to “modernize the State” under the tutelage of Musk, begins to be questioned even between related sectorsgiven its opaque growth and the lack of accountability. His model (which combines entrepreneurs, technologists and actors outside the public administration) was sold as a response to the traditional bureaucracy, but it is generating fissures in institutional security and control systems. The case of Farritor and Ramadapeople without experience in intelligence or defense, shows the risks of introducing private operators in the ultrasecreta spheres of the State without proper safeguards. While the Department of Energy avoids giving explanations about why these accounts were created, analysts such as Hans Kristensen, of the Nuclear Information Projectthey warn that even unlacified budgets require delicate technical referencesand that any “ajar door” can have unpredictable consequences. A parallel state. The truth is that, far from being an isolated incident, Doge insertion into nuclear networks reveals a broader and more dangerous trend: the emergence of a administrative power not electedwith access to privileged information, but without clear legal mandate or sufficient democratic supervision. If you want also, it implies that the logic of “technocratic” access overlaps institutional logic, and in that scenario the state becomes a testing ground for Operators with own agendas. The consequences of this reconfiguration are still in development (even overlaps Musk’s output), but the scandal leaves a warning meridianly clear: when the obsession with efficiency eliminates controls, which is gained at speed can cost very expensive, at least, In security.

Nuclear power plants have a very valuable resource so as not to collapse if electricity fails: the “flex” strategy

The refrigeration system of The reactors of nuclear centrals It has a fundamental purpose: to guarantee that Fuel bars will remain at all times within Its operating temperatures range. If this parameter increases excessively they could melt and trigger a serious accident. To avoid it Conventional nuclear reactorslike those we have in Spanish nuclear plants, have a triple cooling circuit. The primary circuit consists of the vessel that contains the fuel bars and a deposit known as heat exchanger. The hot water from the vessel circulates between both deposits thanks to the action of a pump, so that it cools in the exchanger before returning to the vessel. This circuit is closed. In addition, the heat exchanger acts as a steam generator, so a second circuit is responsible for introducing the cold water inside that, when coming into contact with the hot water of the primary circuit enters 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 steam is cooled and condenses inside an additional tank to promote the appearance of water in the liquid state that will be introduced again in the heat exchangerthus 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 external 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. In modern nuclear centrals flexibility and redundancy are everything As we have just verified, so that the water that acts as a refrigerant element circulates correctly inside the primary and secondary circuits the action of at least two pumps is necessary, one for each circuit. And, of course, the pumps need electricity to function, like many other elements of the nuclear reactor, such as the pressor, the external cooling circuit pumps or the safety injection pumps. We explain everything in more detail in the article that we dedicate to The control rooms of nuclear centrals. Portable equipment allows all these functions to be performed without having to depend on exterior power supply After Fukushima The safety of all the world’s nuclear power plants was reinforced. They underwent very important stress tests during which all the central parameters were reviewed, especially those that were related to what had happened in Fukushim Baskets on the electricity grid. And once everything was reviewed, the incorporation of a series of measures to mitigate and prevent such accidents was standardized worldwide. This strategy is known as “flex”, which is the flexibility apocope. Nuclear centrals have been designed to Prevent Design Base accidents. This philosophy consists in thinking about what can happen with the purpose of implementing security measures to mitigate them in case they occur. What happens is that in practice, of course, there are accidents that you can not have planned, so in addition to the security systems prior to Fukushima, a series of portable equipment that allow all those functions from outside without having to depend on exterior power supply have been incorporated. They are totally portable and autonomous equipment that are already incorporated into all nuclear plants, and that can also be transported from one central to another in case of need via helicopter or through the military emergency unit (UME). In addition, there are also A central warehouse in Technatom Madrid where there are portable equipment that could be transferred in two or three hours to any Spanish nuclear power plant. As we have just seen, the redundancy of the equipment is also a crucial strategy in nuclear facilities. However, there is another resource that is even more important: The security culture. The training of all people who work in a nuclear power plant is individualized and permanent throughout their professional career. In Xataka | China and Russia have an extremely ambitious plan: in 2028 they will build a nuclear power plant on the moon In Xataka | This nuclear reactor is different from everyone else. It has been expressly designed for data centers

In 2028 they will build a nuclear power plant on the moon

Yuri Ivanovich Borísov, former Vice Minister of Defense of Russia and currently at the head of Roscosmos, the Russian Space Agency, confirmed in March 2024 that China and the country led by Vladimir Putin planned to install a nuclear reactor on the surface of the moon. Russia’s long experience in the development of nuclear infrastructure is beyond doubt. And China, although it has later reached this industry, has scientific capacity and resources necessary to get airy. Its plan is to have the International Lunar Research Station (known as Ilrs for its acronym in English). Russia and China will operate it jointly, but for this installation to come to fruition it is essential to develop an energy source that guarantees a stable and sustained supply over time. This is the need that precisely aims to solve these two nations building A small nuclear power plant On the lunar surface. The starting gun will arrive in 2028 Pei Zhaoyu, the chief engineer of the Chang’e-8 mission, has confirmed This week how relevant Russia’s participation is in this project: “An important issue for the Ilrs is the energy supply. In this field Russia has a natural advantage because in regard to nuclear facilities, and especially sending them to space, leads the world even ahead of the US.” The Chang’e-8 mission will give the authentic departure gun to this very ambitious program. The International Lunar Research Station will be permanently inhabited from 2030 And it is that China plans to launch it in 2028 with a double purpose: initiate the preparation of the lunar base that will be permanently inhabited from 2030 and explore the construction of the nuclear reactor that will be responsible for the main delivery of energy to the station. As we have seen some lines up, both facilities They should be finished in 2035. Interestingly, the Chinese government has not yet officialized its approval of this plan, but the statements of Pei Zhaoyu corroborate that The collaboration of Russia and China is already underway. In any case, the country’s nuclear scientists led by Xi Jinping already have a preliminary design of their nuclear reactor ready. And it has some novel features. To elaborate it have been inspired by both NASA’s design and the old Soviet nuclear reactor Topaz-II. Your proposal will use Fuel bars Ring -shaped uranium dioxide; A double cooling system that will use liquid metal (NAK-78), and that, on paper, will be able to maintain the reactor core below 600 ºC; And finally, a moderator of Ititrio hydride neutrons that according to Chinese technicians is more efficient than conventional zirconium hydride moderators. Meanwhile the US is preparing His return to the moon through the NASA Artemis program. Its purpose is to place two astronauts on the lunar surface in 2027 and start from this milestone the construction of a sustainable lunar base. This installation will have large solar panels, but photovoltaic energy It is not enough to ensure supply Because on the moon the night endures for between fourteen and fifteen terrestrial days. For this reason The US is also developing a nuclear reactor known as FISION SURFACE POWER (FSP) that will be able to deliver 40 kW of power.

The production of renewables in Europe is so strong that it is forcing nuclear power plants to work

In Europe there is a division around the closure of nuclear. Some countries have already disconnected them at all, such as Germanyor are in the process of doing so, like Spain. Meanwhile, France keeps them as a pillar of its electrical system. However, the arrival of spring has evidenced something that was suspected: the rise of renewables have forced nuclear plants to stop. A lot of light and little demand. The production of renewable energy has saturated the electrical networks in several European countries. According to Bloombergthe immediate consequence has been the fall in electricity prices, which on holidays (Easter and Easter) and with low demand have even become negative. In Spain, five of the seven nuclear reactors They stopped or reduced their burden And, in the case of France, its electric company, known by its acronym EDF, has cut its atomic production in an average of 4GW daily in March, double a year earlier. Negative prices When talking about negative price it may seem that electricity will be free, but it is not. This means that the electric market, based on time auctions, can yield negative prices when there is too much supply and very little demand. In those hours, producers or electrical companies have to pay to place their energy on the network. Renewables, which have legal priority of access, continue to function. On the other hand, nuclear cannot lower their power so quickly and operate in these conditions, especially in countries such as Spain where the tax burden has increased by 71% since 2019, According to PWC. The clean boom. The rise of renewables is promoting many countries to operate with energy 100% cleanrecently Spain He joined this new coverage. Yes, it is true that the increase in installed total capacity has grown vertiginously in a few years, reaching almost 700 GW According to the Global Energy Review 2025. In this commitment to clean generation systems, storage systems also enters batteries either Reservoirsin addition to creating A good electric structuredespite the fear of companies around The uncertainty of the closure of nuclear. What about nuclear energy? If the nuclear operate less hours and with low prices, they lose profitability. And if they also have to stop and restart due to demand variations, costs rise and technical risks increase. As has detailed The New York medium, France, with 70% of its electricity still of nuclear origin, is seeing how that technical rigidity collides with a system in transformation. EDF has warned that frequent variations hinder maintenance and routine tests. Spain already has put closing date To all its reactors between 2027 and 2035, and other countries follow that path. Forecasts According to Staffan Bergh, chief analyst of Bodecker Partners: “We will see many more hours with negative prices, and these will only increase during spring.” In this line the analyst explained that it is not necessary to install more renewable, but in knowing how to use them well, manage them better and complement them with intelligence.

The US promised them very happy resurrecting its nuclear industry. Now a problem with tariffs has been created

The commercial war that He has started United States this April has given much to talk about, especially for Tariff dispute with China. This situation has put an old energy problem on the table: the dependence of foreign uranium. An uncomfortable dependence. The policies of the current American administration They have made clear their position not to continue towards the change of the energy transition. The Trump approach is placed in fossil fuels, but in nuclear matters it was preceded by Biden. In this specific case the energy constant is has maintained Between both governments, which in the road map left that nuclear energy should triple. In this way, the United States has been importing 99% of Uranium concentrate to make fuel for your reactors. In addition, the 54 nuclear centrals of the country generate about a fifth of all the electricity it consumes, According to Ciphernews. Who are the suppliers? As detailed in the same medium, most of the uranium has come from Canada, Kazakhstan, Australia, Russia and Uzbekistan, and although this mineral It was exempt of tariffs, the situation can vary Seeing the stage. In short, the issue has generated a stir in the energy sector and has exposed a structural vulnerability in its nuclear supply chain. A bet towards national mining. According to the United States Energy Information Administration (EIA)last year the national production of uranium concentrate multiplied by thirteen, but still is not enough to meet the demand. However, Scott Melbye, president of Uranium producers of America, He has assured that at least six companies have restarted mining operations in the country. It was not always like that. USA It was the largest uranium producer of the world in 1980, but in the following decades other countries ate the land, as was Canada and Kazakhstan because the extraction costs were lower. The situation worsened with a nuclear disarmament agreement of the USSR and for 20 years the half of the US nuclear fuel came from the recycling of Soviet uranium. After all this situation, in which it began more and more to depend on the uranium of others came the Fukushima accident in 2011. After this tragedy many countries, including USA, They reduced their investment in nuclear energy. Western mining companies paused operations, while Kazakhstan, with state support, Increased its production without worrying about profitability. Russia also continued to sell cheap uranium, even after the end of the disarmament agreement in 2013. Will it be self -sufficient? The orientation of Trump’s policies It seems to point towards the reactivation of its internal nuclear supply chain. Although uranium is still free of tariffs, global tension, technological advances and energy urgency are pushing the country again to look at their own subsoil. The big question is whether this rebirth will be sufficient and sustainable in the long term.

China has a new hydrogen pump. It is so destructive that it seems nuclear

The hydrogen pump is The most terrifying weapon created so far by the human being. A conventional atomic bomb as the ones that launched the USA about the Japanese cities of Hiroshima and Nagasaki, and with which The Second World War concluded In 1945, it triggers a very powerful explosion and the release of a huge amount of energy by firing a uranium -235 or plutonium -239 nucleus. However, a hydrogen pump is even more devastating. It is also known as the thermonuclear weapon, and, very broadly, it uses a small atomic fission pump as a detonator device for induce fusion of the fuel composed of two hydrogen isotopes: deuterium and tritium. The energy that is able to release one of these bombs can be much higher than that of a conventional atomic weapon. In fact, the “Tsar bomb”which is the most powerful thermonuclear weapon so far, was thrown by the Soviet Union on the Barents Sea in 1961 and reached a power of 50 megatones. China has just tested a new type of hydrogen pump To understand with some precision how the bomb that China has developed works and why it is not a nuclear weapon it was necessary to briefly review what are the principles of operation of atomic bombs and thermonuclear weapons. The Complete Prohibition Treaty of Nuclear Essays approved by the United Nations General Assembly on September 24, 1996 prohibits any type of nuclear test. Unfortunately, this agreement has not come into force because it has not been ratified by all countries that have nuclear weapons. This weapon uses magnesium hydride (MGH₂) because it is a chemical compound capable of storing hydrogen in a solid way In any case, as I mentioned, the bomb that China has tried is not a nuclear weapon. Unlike the hydrogen pump in which we have investigated a few lines above this weapon uses as a magnesium hydride fuel (MGH₂) because it is a chemical compound Able to store hydrogen in solid way. This fuel is stable from a thermodynamic point of view, but it has a peculiarity: it reacts in a violent way when it comes into contact with water or acidic substances, releasing hydrogen. Once its release has occurred, this chemical element enters into combustion, reaching a temperature of up to 1,000 degrees Celsius. However, its destructive capacity is not the consequence only of the temperature reached by the fireball it produces; His devastating power is also linked to the fact that he calls her lasts for more than 2 seconds. It may seem little time, but it is not. It is a long time. In fact, the flame of a TNT explosion hardly lasts 0.12 s, so its destructive capacity is much lower. Of course, the explosion of this hydrogen pump is approximately 60% less powerful than that of a TNT device in terms of pressure. What China has carried out for the moment is just a test, but this country already has a factory capable of producing 150 tons of magnesium hydride per year. It is evident that this nation is serious with this weapon. Presumably it can be used to destroy drone swarms, end objectives endowed with state -of -the -art shields or ravage a wide area of ​​land, among other possibilities. Hopefully neither China nor any other country decides to use this type of weapons in the future. One last note: we do not know what the appearance of this pump is, although it weighs 2 kg, so it is not very large. Of course, the explosion you can see in the cover image of this article is real.

Now there is a naval base with six nuclear submarines

In recent months, satellite images have revealed some of the latest military key in China. In October 2024 a new missile launch point was discovered in A strategic island. In November it was the appearance of a mysterious ship whose dimensions left few doubts of their reach, and a few weeks ago the largest military center of the planet. The latest: a base with six surprises. A hidden base. What happened has been possible through a Image update Satellite on Google Earth. Only then, Naval Analyst Alex Luck He found something That was not before: the presence of at least six nuclear submarines in the first submarine base in Qingdao, in the province of Shandong, China. The same, located at a strategic point with direct access to the yellow sea, the Eastern China Sea and the Japan Sea, has been a high military sensitivity installation for years, but now it can be observed with relative clarity from public services of digital cartography. In other words, the active existence of a secret base of nuclear submarines where, as explained by the analyst, several docked nuclear submarines are identified, a revelation that confirms not only the sustained expansion of the Chinese underwater fleet, but also its growing commitment to reinforce strategic deterrence through naval power. The submarines. The images from the space show at least six docked nuclear submarines, including two of Type 091 classtwo of class Type 093A and unidentified, in addition to a dry dike submarine that could be dismantled. Also, According to the analysta Type 092currently out of service and replaced by the most modern Type 094. Said form, we would be facing five nuclear propulsion submarines (although these with conventional weapons), and at least one with nuclear ballistic capacity (SSBN). Plus: The base, which as we said until now had remained under a relative veil of secrecy, points to a centerpiece in the growing maritime expansion of China. A Chinese submarine Type 094 Evolutionary deterrence. China currently has some 600 Nuclear Ojivasa modest figure compared to more than 5,000 from the United States, but enough to unleash a winter global nuclear in case of conflict. We have commented beforealthough Beijing maintains a policy of “Not first use” Of nuclear weapons, the country has begun to diversify its strategic arsenal, traditionally dependent on terrestrial and aerial platforms, through an expansion of its underwater force with nuclear capacity. A THREAT INITIATIVE NUCLEAR REPORT He stressed that the Navy of the Popular Liberation Army (Plan) operates both nuclear propulsion submarines and a robust diesel-electric submarines, the latter being the back spine of its underwater power. However, the recent focus seems to modernize and expand its naval nuclear component, with expectations that its total fleet reaches 65 units by 2025, According to estimates of the US government, and 80 by 2035. China goes very seriously. In the last fifteen years, China has built twelve submarines of nuclear propulsion: two Type 093 (Shang I class), four Type 093A (Shang II) and six Type 094 (Jin Class), the latter equipped with ballistic missiles launched from submarines (SLBM) as The JL-2 (CSS-N-14) and the most advanced JL-3 (CSS-N-20), thus representing the first marine nuclear dissuasion truly credible of the country. Each submarine Jin class can transport up to 12 missiles, and They were shown Publicly during the parade for the 70th anniversary of the Foundation of the Republic of Popular in 2019. In parallel, the imminent construction of the new Type 096 is expected, which will operate together with the Type 094 during the 2030s, as part of that Objective marked by Xi Jinping of significantly strengthening this strategic branch. The underwater race. No doubt, the discovery of this active and visible base from satellite is One more sample How the limits of strategic surveillance They have diluted in the era of digital cartography. However, and beyond the technological anecdote, the finding illustrates the growing role that marine deterrence will play in the Chinese nuclear strategy. With a fleet every time more advanced And a leadership determined to project power in the Western Pacific, the submarine program of the plan represents a critical dimension in the new geopolitical balance. The challenge does not reside solely in the number of submarines, but in its technology, capacity for stealth, autonomy and strategic armament. As China continues to develop Its presence under the waters, Qingdao’s revelation serves as a reminder that the next great struggle for nuclear supremacy may not be seen from the surface, but observe (as now) from orbit.

a nuclear missile that pursued goals

In 1945 the Second World War. He did not do it with him Atomic bombardment From the United States to Japan, but it is evident that these two events marked a turning point in the conflict. However, tranquility did not last long, since the US and the USSR entered the Cold war. In technological, it was a period in which both powers entered a war of spatial, technological and military development And, perhaps, one of the biggest follies was the United States Diamondback missile. Nuclear explosion. In that period, the two blocks They took run in the development of Nuclear bombs. Only 10 years after the end of World War II, the world’s nuclear arsenal was from some 3,000 heads. In 1965, they exceeded 37,000 nuclear weapons, and followed the climb to the peak of 1986: 7,300 nuclear weaponsbelonging 40,159 to the USSR and 23,317 to the United States. Not only were many bombs, but also bombs as devastating and unimaginable as the Tsar pump. And beyond these pumps of several tons of weight, from the ground and sea the ballistic missiles could be launched that were huge again and weighed very much. An idea occurred to the United States: what if we develop a nuclear missile that can be armed in airplanes and is not focused on destroying terrestrial objectives, but aerial? Sidewinder. In the middle of the century, the US was investigating the development of an air-aire missile with objective monitoring capacity. It was not an American idea, but of Nazi researchers who designed missiles with rocket propulsion systems. They did not implement it, but they did create a prototype: the Blohm & Voss BV 143. It was an anti-buque plain pump. The allies collected this information when the war ended and, in 1946, in the Naval Ordnance Test Station (or NOTS) in California, an American research team began to develop an air-Aire missile that could persecute its “prey”. In 1951 the project received official financing and, after years of evidence, in 1956 the missiles Sidewinder They went into service. Diamondback. Seeing the success of the Sidewinder program, the United States Navy wondered if they could do something like that missile, but big. In 1956, in the NOTS they began to make designs for a missing missing objectives that, in addition, had the ability to carry a nuclear head. They baptized him as Diamondback. Diamondback sketches China Lake Alumni video image It would be very far in power of other nuclear weapons of the time, since it would have “only” 0.75 kilotons, but in an air-air missile, the resulting explosion would be a real barbarity. Its specifications were much more advanced than those of a Sidewinder and would be faster, reaching higher speeds. Mach 3 Thanks to a double impulse system with liquid propulsion, it would have a much larger operational range and a flight roof of up to 24,000 meters. In this video, we can see some of the developments and prototypes of the American base: Air-Aire, but to the beast. The idea of ​​putting a nuclear head on a missile may seem curious, but in the marine minds it made sense to end entire formations of enemy bombers flying in closed formation. The explosion of a Sidewinder could end enemy fighters and a bomber if it gave at the indicated point, but a missile of 0.75 kilotons would spray in the air to its goal and those who fly next to it. It was also designed to supply the deficiencies of the original Sidewinder not only in terms of scope, speed and destructive capacity, but in mobility. The liquid fuel allowed it to maintain energy and speed throughout the flight, optimizing those possible final maneuvers if the objective intended to escape. In addition, the guide system did not settle for infrared, but also had a passive radar that not only increased the probability of impact, but allowed to achieve objectives from any angle. The Air-Aire missiles of the moment could only be guided by the heat of the propellants, so they had to launch while behind the target. The advanced monitoring system allowed to launch it from any angle | China Lake Alumni video image He did not set. In spite of everything, the project just lasted a year. Prototypes were not created and the missile did not leave the design table because the Navy did not have, in those moments, specific needs to assemble nuclear missiles and its development with the technology of the time would have been complete and extremely expensive. The Sidewinder prevailed. A year later, the United States did developed an air-aire missile with a 1.5-kilotons nuclear eyes and deployed for almost 30 years in the US and Canadian air forces. He Air-2 Genie It had more power than diamondback, a similar weight, it also reached Mach 3 speeds … but it wasn’t guided. Precisely, the terrifying diamondback was not so much the nuclear eye, but the very advanced monitoring system, a characteristic that the AIM-26a Falcon of the 60s (less powerful and slower than what Diamondback wanted to be). Thus, Diamondback remained a sample of that nuclear ecstasy in which the two powers entered. The one who followed on his way, and with an overwhelming success, was the Sidewinder. Over the years, the missile evolved with greater speeds and benefits, as well as the implementation of semi -active radar systems with which he wanted to flirt the diamondback. And, since its launch in the mid -50, it is part of the military arsenal of countries throughout the world, inspiring Soviet developments such as the K-13 or the PL-2 Chinese. Maybe, as they point out in TWZDiamondback was a “too much and very soon” for the navy, but it is evident that it would have been an incredible technological piece and – another deterrence in nuclear war.

It was an abandoned nuclear power plant. Now he has a second life as the most silent acoustic laboratory on the planet

Two gigantic cooling towers of almost 150 meters high flank what clearly seems to be a nuclear power plant in a rural Washington area. It is actually the acoustic laboratory NWAA Labs, one of the most silent buildings on the planet. An abandoned nuclear power plant. The laboratory was built on the vestiges of a pharaonic project that never saw the light, the nuclear washington Projects of Elma. Plants 3 and 5, part of what was intended to be the largest nuclear energy complex in the United States, were abandoned in the 80s without fissting a single atom. Designed to resist all kinds of impacts and earthquakes, the structures would have been extremely expensive to demolish, so the NWAA Labs adapted to them. The reactor is the reverberation chamber, the turbine room is the anecoic chamber and the old reactor control room is the laboratory control room. The facilities, still marked, remain a “disturbing” maze. The ideal facilities. The NWAA Labs is a project by Ron Sauro, an electrical and mechanical engineer formed in Stanford that combined its beginnings in NASA with being the keyboardist of the group The Rivieras, authors of a gold record in 1963. After a life designing sound systems, Sauro saw the unique potential of this nuclear power plant abandoned to bombing proof. The outer structure, with walls of 1.5 meters thick and eight layers of reinforcement bars, is designed to support an earthquake of magnitude 10 and the direct impact of an explosion of 10 megatons on its roof. The interior structure is isolated from the surrounding terrain by a ditch that minimizes the transmission of vibrations and noise. In another ditch within this, a circular and steel circular container is erected, originally intended for the nuclear reactor. The entire installation rests on a sandstone layer of more than 3,000 meters thick. An almost absolute silence. Thanks to these structures, the NWAA Labs presumes to have the two largest reverberation cameras in the world. Salas where the sound bounces up to 28 seconds without absorbent material, which allows to measure the sound power of a source or the absorption capacity of a material. In addition to the reverberation cameras, the laboratory has anechoic cameras designed to absorb sound and simulate a space without reflections. In these rooms, silence is almost absolute. The background noise is -43 dB (below the human hearing threshold). In the old turbine room, 198 meters long by 106 wide by 24 high, the reflections take so long to arrive (more than 160 ms) that do not interfere with some measurements. Who uses this laboratory. The NWAA Labs performs tests for the audio industry. The speakers are 20% of their business: over here more than 3,000 speakers of some 300 professional brands and high fidelity have passed. But it is also offered to other industries, which prove construction materials, acoustic insulation here, and even noisy washing machines or aircraft cabins. The laboratory also attracts musicians, video game and filmmakers, fascinated by their acoustics and post-apocalyptic aesthetics. Image | Walter Siegmund (CC By 2.5)
