The US is using an exascale power supercomputer to solve the biggest challenge of nuclear fusion

by

The Frontier supercomputer at the Oak Ridge National Laboratory (ORNL) linked to the US Department of Energy is one of the most powerful on the planet. In fact, it is currently the second most capable exascale supercomputer after El Capitan according to TOP500 ranking. These machines are very valuable tools that are already being used by researchers to try to solve some of the most complex scientific problems that humanity faces. And one of them is the behavior of plasma when it is under the influence of a magnetic field. A group of ORNL researchers is using two of the most powerful tools currently available to humans, the Frontier supercomputer and the artificial intelligence (AI), to understand with the greatest possible precision the chaotic behavior of the plasma of stars. An important note before moving forward: plasma is an extremely hot gas made up of particles endowed with an electrical charge, which is why it can be confined inside a magnetic field. This knowledge can presumably help scientists very accurately simulate the supernovaswhich are nothing more than the explosions that occur when a massive star loses hydrostatic balance by burning most of its fuel. When a supernova is triggered, a good part of the chemical elements that the star has produced through chemical reactions nuclear fusion It shoots towards the stellar medium with a lot of energy. From supernovae to experimental nuclear fusion reactors Dr. Eliu Huerta, a computational scientist at the Argonne National Laboratory (USA) who has had the opportunity to supervise the work of the ORNL researchers, express clearly why this scientific initiative is so important: “This type of capability has long been the dream of astrophysicists and many other scientists. This is the first time that this level of understanding has been achieved through AI for systems of this complexity (…) The more chaotic the system, the more difficult it is to simulate it.” Understanding very precisely how the plasma of stars behaves is important not only to have more information about supernovae; It is also crucial for predict solar flaresor even to simulate the interaction of the Earth’s magnetic field and the high-energy ionized atomic nuclei that constitute the cosmic radiation. Frontier’s role in this research is critical: it provides the computational power required to train the models needed to generate thousands of detailed plasma simulations. Inside nuclear fusion reactors it is still a challenge to keep turbulence under control However, there is another application in which this technology has the ability to make a difference: the development of nuclear fusion reactors. We can intuitively imagine a nuclear fusion reactor as a pressure cooker in which two essential ingredients are cooked: deuterium and tritium. In order for the nuclei of these two hydrogen isotopes to fuse and release the neutron that will ultimately allow us to obtain a large amount of energy, it is necessary to confine them in an extremely hot plasma. In fact, for this process to take place it must reach a temperature of at least 150 million degrees Celsius. Scientists know how to do it, so subjecting deuterium and tritium nuclei to the pressure and temperature necessary to make them fuse is no longer a problem. What still represents a challenge is to achieve keep turbulence under control. Otherwise the plasma will be destabilized, its density in critical regions will be affected and sustaining the fusion reaction over time will not be possible. The mechanisms that govern this process are very complex, but little by little physicists and engineers working on fusion energy are managing to understand them better. The research of ORNL scientists seeks to better understand the behavior of plasma confined inside the vacuum chamber of experimental nuclear fusion reactors with one purpose: to minimize turbulence so that energy loss is minimal. And they are on the right track. In fact, they already have a system ready that is capable of delivering very detailed turbulence predictions in just a few seconds, thus reducing errors by more than half compared to previous methods.

NASA wants to head to Mars in December 2028. To achieve this, it is going to use something: nuclear reactors

by

Virtually all major space companies They agree that the future of space exploration involves feeding ships with nuclear energy. For this reason, NASA has already set a date for its first interplanetary trip with nuclear-electric propulsion. It will be possible thanks to Space Reactor-1 (SR-1) Freedom, which will be launched in December 2028 heading to Mars. Destination: the red planet. NASA has long shown interest in carrying out this launch in 2028. Now, the company has assured that everything is going at a good pace and that, if it continues like this, the date could be closed around the last month of this year. In order to meet deadlines, technologies previously tested by NASA are being used. Some, for example, come from the Lunar Gateway Station, whose development is currently paralyzed. With these technologies, together with a new nuclear reactor system, a trio of helicopters similar to Ingenuity, baptized as Skyfall, will be taken to Mars. The classic and the new. The SR-1 actually runs on a closed Brayton system, which is very common for power. Normally, in these types of systems A combustion reaction takes place, which produces energy in the form of heat. This is used to heat a gas, which expands and drives a turbine. The result is mechanical energy that can be used, for example, to obtain electricity. Then, when the gas cools, a new cycle begins, which is why it is said to be a closed cycle. In the case of the SR-1, everything is almost identical. The only difference is that, instead of a fuel, a nuclear fission reaction is used to obtain the heat. Thus it is not necessary to transport large quantities of fuel into space. Just a chain reaction like those used in nuclear power plants. electric motors. The electricity obtained in this closed cycle is used to power electric motors in a process that is activated 48 hours after launch. Afterwards, you can stay active during the entire year of the trip to Mars. On the other hand, this same electricity can also be used for other purposes, such as communications with Earth. Also on the Moon. The main application of nuclear energy in space will be in very long-distance travel, where the ships are so far from the Sun that solar panels are no longer useful. However, it can also be useful at much shorter distances. If this trip to Mars goes well, NASA plans to be able to use these technologies at a lunar base installed in Shackleton Crater. Strategically it is a good locationbut it has the disadvantage of being continually in shadow, so solar energy cannot be used. Nuclear fission could be much more useful. 60 years of research. In reality, the SR-1 is the result of 60 years of research, with an investment of 20 billion dollars. Although it may seem like something new, there is a lot of work behind it. Still, if NASA’s projects go as planned, they will be time and money well spent.

In 1953 Hollywood filmed a blockbuster in front of US nuclear tests. It was the most radioactive movie in history, literally

by

Year 1953, during a nuclear test in the Nevada desert, several Las Vegas hotels offered their guests privileged views of the mushroom cloud at dawn as if it were a tourist attraction at Disneyland, with cocktails included and terraces full of spectators. The scene, which is difficult to imagine today, reflected the extent to which certain risks were perceived very differently in the midst of the nuclear age. Filming in the Cold War. In the mid-50s, The Conqueror It was born as a historical blockbuster that from the beginning involved decisions that were difficult to justify, such as choosing John Wayne to play Genghis Khan himself under the production of Howard Hughes. Filming moved to locations in Utah, an area that offered spectacular landscapes but was, at the time, close to areas where the United States was filming atmospheric nuclear tests. The context was not a secret, but its risks were not fully understood either, since public and scientific perception of radiation was much more limited than today. That combination of cinematic ambition and geopolitical moment left a scenario that, seen with perspective, is much more disturbing than what it seemed like then. The real environment. This perfectly documented that nuclear testing in the Nevada desert generated radioactive fallout that moved to populated areas, subsequently affecting known communities as “downwinders”. It is also proven that the filming team worked in one of those regions, and that part of the surrounding material was transferred to other sets, potentially expanding exposure. This context is neither a theory nor a subsequent reconstruction, but a historical fact recognized by investigations and official organizations that have studied the consequences of those tests. The passage of time and the uncomfortable statistics. What happened? That, over the years, a significant part of the cast and production team developed cancerincluding figures such as John Wayne himself (who died of the disease in 1979), Susan Hayward and Dick Powell. The most cited figure that gives an idea of ​​the possible impact speaks of more than 90 cases among about 220 people linked to the production, a fact that has fueled the fame of the filming as one of the most disturbing and cursed in the history of Hollywood. Even so, we must remember that this number comes from of informative accounts and not from controlled epidemiological studies, which requires treating it with some caution despite its impact. What is proven and what is not. The line between facts and story is key in history. It’s proven that there was exposure to a potentially contaminated environment and that several team members developed serious illnesses over time. What is not proven is a direct causal relationship between filming and these cancers, since factors such as personal habits (including smoking) and the lack of comparable clinical data, facts or causalities may enter, making any definitive conclusion difficult. Therefore, the case remains an ambiguous terrain: perfectly plausible in its approach, but not scientifically confirmed. From failure to modern myth. Upon its release, the film was received quite coldly and criticalremaining in the popular imagination as another failure within the industry. However, as the decades passed, his memory has changed completely, transforming into a story that combines Hollywood, Cold War and invisible risk. What at the time was simply a bad creative and logistical decision ended up being reinterpreted as an episode from the world of celluloid. loaded with symbolism about the limits of knowledge and (i)responsibility. The context changes everything. Because the story of The Conqueror lies not only in what happened during filming, but in how that same filming fits within an era in which exposure to nuclear risks formed part of the everyday landscape. There is no doubt, what seemed acceptable then is today perceived as true nonsense, and this radical change of perspective is what turns the case into something more than a movie anecdote. It wasn’t just a problematic shoot, but an example of how seemingly normal decisions can take on a completely different meaning. with the passage of time.

While everyone was looking at the Middle East, North Korea has had time to do what Iran has not been able to: go nuclear.

by

It happened a few years ago, when in the midst of increasing tensions with North Korea, the Japanese government came to send alerts to millions of mobile phones through the J-Alert system when it detected the overflight of a missile, causing unusual scenes in which trains stopped and citizens took refuge in stations without knowing exactly what was happening. That reaction, almost automatic and difficult to imagine in peacetime, left a clear image of the extent to which certain global balances can be strained without warning. The regime that did not fall. I told a few days ago in an extensive special report the wall street journal the story of the surprising source of North Korea’s enduring power, a nation that has survived the demise of the Soviet Union and the transformation of China because it ceased to be just a communist state and became something more resilient: a closed ideological structurehereditary and almost religious. There it is impossible not to start with the Kim dynasty that managed to consolidate a system in which power is not only exercised, but also believed, internalized and transmitted as a faith. That model, built from Kim Il Sung and perfected by his successors, has made it possible to maintain extraordinary internal cohesion even in conditions of extreme isolation. While other regimes eroded as they opened up to the world or collapsed under external pressure, Pyongyang consolidated a base of control much deeperdifficult to dismantle from the outside. From ideology to state religion. I remembered the Journal that the core of that system is not only political, but also symbolic and emotional, with elements that clearly recall an organized religion. The Juche ideology It progressively replaced classical Marxism, incorporating rituals, symbols and an almost messianic narrative around the leader. The omnipresence of Kim Il Sung, his conversion in “eternal president” and dynastic continuity have generated a structure of loyalty that goes beyond political obedience. This model, influenced indirectly through Christianity that once dominated Pyongyang, allowed the construction of a system where loyalty to the leader is perceived as an absolute truth, something that largely explains its stability and capacity for resistance. The silent military leap. On that internal basis, North Korea has developed a pretty clear strategy: to arm oneself militarily until one becomes practically untouchablealthough no one knows exactly how much of it is true. Today it is recognized that it has intercontinental ballistic missiles capable of reach US territory and has reinforced its arsenal with increasingly sophisticated systems. Not only that. The recent tests, just a few days ago from their new destroyer, with high-precision cruise and anti-ship missiles, they clearly show that it is no longer just a matter of accumulating weapons, but of integrating them into a modern military architecture, with rapid response capacity and systems resistant to interference. In fact, accelerated construction of new warships It aims at a transition from isolated platforms towards a structured naval force, which expands its projection capacity and complicates any containment scenario. Nuclear expansion in full noise. I told it this week Guardian through internal analyzes held by the UN nuclear watchdog. While much of the international attention was focused on the conflicts in the Middle EastNorth Korea has been taking advantage of this context to advance its nuclear program without restraint. As? Activity at key facilities such as Yongbyon has intensifiedwith new reactors, reprocessing plants and possible undeclared facilities to enrich uranium. The agency’s estimates point to dozens of warheads already operational and a growing capacity to produce enough material to between ten and twenty weapons additional each year. In other words, this rhythm, sustained over time, indicates that the objective is not only basic deterrence, but rather reaching a volume that guarantees the survival of the regime in the face of any attempt at forced change. The power that Iran has not consolidated. The key difference here is that North Korea has achieved what other countries in similar situations have achieved (call it Iran) have not been able to: convert their nuclear program into a fully integrated tool in their survival strategy. While other powers under international pressure have seen limited or braked its development, Pyongyang has moved closer to a point of no returnone where its capacity is broad enough to deter any intervention. In this context, it is possible that the real change is no longer just quantitative, but strategic: because when it reaches a surplus of nuclear capacity, the risk will cease to be solely regional and will have global implications, opening the door, at the very least, to new proliferation dynamics.

Not only has the US just lost the “eye” that Hormuz watched, its nuclear aircraft carrier is in Africa for fear of being shot down

by

Year 2019, an American surveillance drone more than 200 million of dollars disappears from the radar over the Gulf of Oman and, a few hours later, Iran shows its remains to the world on television. It was not the first time something like this had happened, but it was one of the most uncomfortable: a machine designed to see everything had been seen before it could react. Since then, in that part of the map, each silence in the systems begins to weigh more than it seems. Losing the “eye” that watched Hormuz. Confirmation of the fall of MQ-4C Triton a few hours ago is not a simple technical incident, but the loss of one of the most advanced pieces of the US surveillance system in the Persian Gulf. This drone, capable of operating at high altitude for hours and equipped with cutting-edge sensors, was key to monitor naval movementsdetect threats and maintain situational control around the strait. His disappearance, under circumstances still unclearleaves a most uncomfortable void at a time when every piece of information matters, especially in an environment where mines, drones and speedboats turn any mistake into a real threat. The “scared” aircraft carrier. Plus: the diversion of USS George H.W. Bush Going around Africa instead of crossing the Suez Canal is not just any logistical decision, but a symptom of that operational vulnerability What Washington is suffering from. The reason? Avoid passing through Bab el-Mandeb It means recognizing that even a nuclear aircraft carrier battle group, one of the most powerful assets in the world, cannot guarantee their security in a strait where actors such as the Houthis have demonstrated the ability to attack ships with drones and missiles. This detour not only lengthens times and complicates deployments, but also shows that military superiority does not always translate into freedom of movement. The uncomfortable precedent. Not only that. They counted the Forbes analysts that the decision of avoid Bab el-Mandeb It raises a disturbing question for the immediate future, because if this step is already considered too dangerous, what happens to Hormuz, much narrower, guarded and saturated with Iranian defensive systems? The logic is a huge question. Iran not only has more advanced technology than its regional allies, but also decades of specific preparation for that scenario. That makes any attempt to operate there a very high risk betand where even a single relevant impact could completely alter the strategic balance of the area. The strategic paradox. If you also want, what emerges from these movements is not that image of overflowing force that is presupposed, but rather of calculation and extreme fear. While American political discourse speaks of pressure, blockade and control, tactical decisions are revealing prudence, we would even say caution. The simple fact that the route of a nuclear aircraft carrier is redesigned to avoid a hot spot shows that the margin of error it’s tiny. And in an environment where a successful attack on a high-value ship could trigger disproportionate military and political consequences, the priority is no longer projecting strength and power, but avoiding losses at all costs. When losing a little is too much. In summary, the combination of drone crash Triton and the rnuclear aircraft carrier odeo paints a crystal clear picture: right now, the United States is not operating from a position of comfort, but rather in an extremely delicate balance. In that scenario, it doesn’t take a devastating blow to change the rules of the game, just with a symbolic one. Because a lost surveillance drone may be acceptable, even if it has the characteristics of the MQ-4C, but a damaged warship or a compromised nuclear aircraft carrier would be a very different story.

Looking to reduce fossil fuels in transportation, Hyundai has the solution: a nuclear container ship

by

About 80% of world trade is moves by sea. Although it may seem like slower transportation, something key to maintaining prices is moving a large amount of material on each trip, something that is out of the reach of trucks, trains and planes. There, the huge container ships They lead the way with the associated problem of enormous spending on fossil fuels. The industry is looking for alternatives to operate no carbon emissions and Hyundai has a clear path. A nuclear container ship. Pioneer. HD Korea Shipbuilding and Offshore Engineering is the naval branch of the company and, in 2025, they presented a model of container ship nuclear seeking to eliminate emissions of a large ship with electric propulsion powered by a small nuclear reactor. The reactor type would be an SMR with thorium-based fuel and liquid salt as a coolant. After months working on the plan, this 2026 HD and ABS (American Bureau of Shipping) they arrived to an agreement to jointly develop the vessel. This is something that is in the design and subsequent prototype phase, but the agreement between the two lays the foundations for the development of a ship that is expected to be the first nuclear container ship. 16,000 TEU class. The class of a container ship is measured by the TEU, or Twenty-foot Equivalent Unit. Basically, x number of 20-foot-long containers, 16,000 containers at a time in the case of the Hyundai ship. It is far from the 20,000 and 25,000 TEU vesselsbut it will be a step forward in the maritime mobility of the future. Furthermore, the ship will not need to be as massive as others thanks, precisely, to that nuclear propulsion. By replacing the conventional machinery of diesel engines, exhaust systems and huge fuel tanks with a nuclear compartment and electrical systems, there is free space to transport more containers while maintaining the ship’s compact size. Compact within what these monsters are. Armor. To guarantee radiological safety, what this ship must include is a double stainless steel tank shielding system designed to ensure that there are no radiation leaks to both the inhabited areas of the ship and the ocean. The liquid salt itself as a coolant will also act as a safety measure against reactors that require pressurized or boiling water. If SMR stands for ‘Small Modular Reactor‘, MSR respond to ‘Molten Salt Reactor’, and basically means that, in case of emergency, the salt mixture can solidify to stop the reaction, being another security measure. all the sense. For now, the Hyundai ship has received the approval of its partner – an advantage of being the body that is also in charge of these things – but it is a project. The next steps are development and prototype, so there is still no authorization for the construction of the ship. However, it makes perfect sense for container ships to switch to nuclear propulsion. It is something that we have already seen on large ships like aircraft carrier and submarinesand the main advantage (apart from reducing emissions) is that life on the high seas depends solely on how much food can be loaded on board. Obviously, the investment is more expensive initially because it is not cheap to change the mobility paradigm, but it would not be tied to fluctuations in the price of fuel for transportation, something that we have been seeing recurrently in recent years and that, obviously, changes the shipping price. Alternatives. Hyundai is not the only one in this race and its national competitor Samsung also has a project in the oven. China, or Norway, transport heavyweights, They also have concepts of container ships powered by nuclear reactors. In the end, the industry must move because the International Maritime Organization is regulating greenhouse emissions and demanded reductions of 20% by 2030 with the aim of achieving neutrality by 2050. A render of China’s nuclear container ship In that sense, maritime transport not only represents 80% of the transport of all goods, but is responsible for 3% of global CO2 emissions of human origin. Now, nuclear electric motors are not the only way and recently we are seeing that the industry is exploring the path of battery electrification and even the return of a technology that seemed forgotten: the candles.

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

by

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

for whatever reason, it resists nuclear explosions

China has just landed a project that has been on the table for a decade: that of the first floating island of deep sea research of the world. It looks like an oil well, but it is actually a megastructure that is prepared for everything. And, when we say “everything,” we include the end of the world. Because it is a research center, but also a command center and a nuclear bunker. And it has already raised concerns about possible dual use by China. In short. A few months ago we echoed the China’s plan to formalize this project that has been in the oven for years, but that has not materialized. It was now when, according to the state channel CCTV Newsthe country will begin the final phase of design and construction of the platform. The name by which it has been known until now is the “Deep-Sea All-Wather Resident Floating Research Facility”, and it will basically be a facility that can do everything. The installation. Jio Tong University in Shanghai is in charge of the bulk of the project, a platform that will have a double twin hull of 78,000 tons and scandalous dimensions. We are talking about 138 meters long, 85 meters wide and a main deck located 45 meters from the waterline. He Fujianthe brand new new generation aircraft carrier from China, has a displacement of 80,000 tons. To contextualize. It is semi-submersible and, from the University, they have detailed that it will come to fill a gap that they have detected in the country’s arsenal: that of a research facility that can navigate quickly and remain in an area of ​​operations for prolonged periods. “And, if it reminds us of an oil well, it is because they have been inspired by those facilities, they have combined the design with that of the research vessels and what has come out is… well, what we see in the conceptual image. Investigation. The idea is that the facility can house almost 240 people for months thanks to the backup energy systems and the main objective set out by CCTV News and Jiao Tong University is to explore deep waters and serve as a research field. mining system testingoil and gas prospecting, as well as research into that unexplored ocean floor. Bombproof. But there is a twist. The structure is designed to be a fortress capable of withstanding nine-meter-high waves and category 17 typhoons, the highest for this type of cyclones. It is normal since it will be in areas where the hull can suffer, but what is no longer so normal is that the armor has been designed to resist nuclear explosions. Instead of conventional steel armor, the walls of the complex will be like a sandwich with several layers that will dissipate the shock wave from a nuclear explosion. For construction, it is proposed to use a metamaterial that, under pressure, compresses to create a denser structure than thicker steel panels. The simulations indicated that these walls will resist more pressure than that of a submarine. And that, together with the fact that it will have a command center, has raised some doubts about the possible dual use of the facility. Mapping the terrain. Because the ocean floor has become the new battlefield. We don’t even talk about space, since the United States claims that There has been a war with China and Russia for months for control of space, but the launch of this platform project comes shortly after the publication of some information that reveal how China has deployed dozens of research vessels to map the ocean floor. According to reports published in Reutersdozens of ships have been studying the terrain for years, mapping it and deploying sensors in a strategy to be able to monitor in real time data such as water temperature, salinity, the best prospecting areas and… also everything that moves in that territory. From the United States it has already been raised the voice pointing out that these civilian research vessels “can” collect military intelligence, which represents “a strategic concern.” This systematic mapping, for some military analysts, has a single objective and it is not to find oil wells: it is to erode the advantage that the United States had in the oceanic battlefield.” And a facility like the one they are now preparing with their sights set on 2030 can be a true marine fortress.

We wanted electric cars and solar panels. The Hormuz blockade has returned us to the era of coal and nuclear energy

by

The Third Gulf War has caused what decades of climate summits tried to avoid: the effective closure of the Strait of Hormuz has erased 20% of the world’s supply of oil and liquefied natural gas (LNG) in one fell swoop. Faced with the imminent threat of a large-scale blackout, governments around the world have put their energy transition plans in a drawer. However, to keep the lights on and the economy afloat, the immediate response has been to look back to the past: burn coal by the piece and resurrect nuclear power. The mirage of “bridge fuel.” Asia buys more than 80% of the crude oil and gas that transits through Hormuz, but the problem goes far beyond a simple ship jam. This crisis has destroyed one of the great pillars of the energy transition. As explained The New York TimesLiquefied Natural Gas (LNG) was sold during the last decade as the perfect “bridge fuel”: less polluting than coal, more reliable than intermittent renewables and capable of being transported by sea to any corner. That bridge just blew up. The damage is far from being repaired, and it is estimated that the infrastructure attacked It will take years to operate again. Added to this is that Iran has turned the Strait of Hormuz into a kind of maritime “VIP discotheque”deciding by hand which ships can cross. No one can depend on LNG ships to guarantee their sovereignty. The main problem: live without pantry. But there is a technical factor that has turned this crisis into an immediate catastrophe: lack of storage. Unlike the West, most Asian countries lack underground gas stores, leaving them completely exposed to supply disruptions. While nations like South Korea can last up to 52 days and Japan about three weeks, Taiwan walk on a wire extremely fragile, with a legal security threshold of just 11 or 12 days of reserves. Without a “pantry” to store the LNG, Asia has no room for maneuver: if the ship does not arrive on Monday, the blackout begins on Tuesday. This structural vulnerability is what has forced an unconditional surrender to coal. Coal’s dirty lifesaver. As Jonathan Teubner, the aforementioned analyst, perfectly summarizes by Financial Times: “No coal ship passes through the Strait of Hormuz.” That is the key to everything. Being a cheap, abundant resource that does not depend on the troubled waters of the Middle East, the most polluting mineral has returned with a bang. According to FortuneSouth Korea has removed the 80% operational cap for its coal plants, a decision that has drawn the ire of environmental groups who accuse the government of using “energy security as a pretext.” Thailand, for its part, is restarting plants it had dismantled last year. From Seoul to New Delhi: the dilemma of the powers. Japan, one of the world’s largest gas importers, has also bowed to the evidence, allowing its least efficient coal plants to operate at full capacity for a year. Energy desperation is such that in Japan There are already voices demanding cancel the emissions trading system, calling it a “death sentence” for the coal plants they now need to survive. In India, the situation is critical. Prime Minister Narendra Modi has warned of a “major challenge” ahead of the summer. To avoid massive blackouts, New Delhi has commanded giants such as Tata Power and Adani Power operate at full capacity, while Bangladesh seeks multi-billion dollar loans. Sam Chua, analyst at Rystad Energy, sums it up in Financial Times: We are not seeing a transition, but a brutal “destruction of gas demand.” Although it is not that simple: the money wall. This coal revival has a glass ceiling. As experts point out in Japan Timesthe banking sector flatly refuses to finance the construction of new coal plants for fear of being left with “stranded assets” (stranded assets) in the face of global climate commitments. That is, countries are squeezing their dirty old infrastructure to the last drop, but they can’t build new ones. Charcoal is the assisted respirator, but not the cure. The atom as a shield: the great redemption of uranium. Panic too has broken atomic taboos. Taiwan, whose government promised a “nuclear-free homeland” in 2016, has announced plans to restart two decommissioned reactors. The Philippines has charted a fast track to atomic energy by 2032, and Vietnam has just struck a deal with Russia to build its first reactors. Uranium is no longer seen as a threat, but rather as the only way to protect the electricity supply against maritime blackmail. The domino effect reaches Europe. What started as an emergency solution in Asia is already infecting the West. The crisis has forced the European Union to break its own historical taboos, admitting that Europe committed a “strategic mistake” by moving away from atomic energy. Brussels has already put 200 million euros on the table to develop Small Modular Reactors (SMR) by 2030. This shift shows a continental fracture: while France entrenches itself protecting its nuclear investment of 300 billion euros and blocks energy interconnections with the Iberian Peninsula, Europe assumes that it cannot guarantee its future solely with the sun and the wind. War rationing in the 21st century. While the plants uproot, the daily suffocation hit the streets. Philippines has declared a “national energy emergency.” In South Korea, the government implores families to take short showers and Samsung has prohibited its employees from driving to work based on the license plate. In Thailand, officials operate with work weeks for four days and they are prohibited from wearing ties in order to raise the temperature of the air conditioning. The collapse is so severe that Thai ambulances have taken to Facebook to beg gas stations to reserve diesel for them to save lives. The collateral damage. The scope of this blockage transcends the electricity bill. If the conflict lasts until June, Bloomberg alert that the barrel could touch $200, a price designed to cause “demand destruction.” This would lock global inflation at a chronic … Read more

China is giving an overwhelming lesson in nuclear power plant construction to the rest of the planet

by

The time it requires the construction of a nuclear power plant From the moment the concrete is poured until the moment it is connected to the electrical grid, it takes between 15 and 19 years in the West; between 7 and 9 years in Asia and the Middle East; and 6 to 10 years in India and Russia. And the total cost of the project usually ranges between 24,000 and 60,000 million dollars. Barakah 4 nuclear power plantin the United Arab Emirates, has four nuclear reactors, took 9 years to build and cost $24.4 billion. On the other hand, the nuclear plant Hinkley Point Cin the United Kingdom, clearly illustrates the execution problems faced by some Western nuclear projects. After several delays Its first reactor will come into operation at best 13 years after the start of construction of the plant. And its final cost will exceed 50 billion dollars. At an intermediate point, Vogtle Unit 4 is established, in the US, which has taken 11 years to be operational and has cost about 35 billion dollars. As can be expected, the number of reactors and the technology they use have a profound impact on the cost of the plant and the time that needs to be invested in its development. Even so, as we have just seen, construction costs and time vary greatly from one region of the planet to another, especially if we introduce China into the equation. And in this scenario the country led by Xi Jinping is unbeatable with a average construction time of 6 years per nuclear plant and a cost of $2,500/kW compared to the 10-year average and almost 8,500 dollars/kW for the rest of the planet. China’s recipe is the most competitive Shangwei Liu explains clearly in the article you published on the website of the Roosevelt Institute what is the strategy that China has devised to reduce the cost and time invested in the construction of its next-generation nuclear power plants. Its plan is based on two pillars: the reconstruction of the supply chain and economies of scale. To a large extent, China’s success is due to the fact that it has managed to create a national supply chain that is immune to the ups and downs and instability of the international market. In addition, it has a lot of qualified labor in all links of its supply chain. There is only one country on the entire planet capable of approaching China’s numbers in this complex and demanding scenario: South Korea. On the other hand, the economy of scale that has given China so much joy in a very wide range of markets also has a place in the production of the components required by nuclear plants. Furthermore, when replacing components manufactured abroad by local elements This Asian country managed to drastically reduce costs during the first decade of this century, and stabilize them during the last decade. However, there is another factor that works in China’s favor and that we cannot ignore: its coordinated industrial policy and stable regulatory framework allow it to carry out long-term planning. There is only one country on the entire planet capable of approaching China’s numbers in this complex and demanding scenario: South Korea. Its latest nuclear plant projects show a cost of between 3,500 and 4,500 dollars/kWwhich places it close to China, with 2,500 dollars/kW, and well below the average of 8,500 dollars/kW for the rest of the planet. This achievement is the result of approaching nuclear energy as an industrial assembly line and not as a set of isolated engineering projects. Again, economy of scale makes the difference. The US numbers are much less favorable. And the total cost of its latest nuclear plants exceeds $15,000/kWalthough presumably this figure will moderate until it barely exceeds the $10,000/kW in future projects. If Western countries want to drastically reduce their costs and moderate the time it takes to construct their nuclear power plants, they will necessarily have to look towards China and South Korea. The reconstruction of their supply chain is essential, and, in addition, they will have to resolve the crossroads posed by the commitment to large reactors, or by compact modular reactors. At the moment there are no other options on the table.
