  • UK moon base dreams stall as Rolls-Royce halts nuclear reactor work

    The UK Space Agency’s plan to develop a nuclear-powered Moon base has stalled after Rolls-Royce placed its lunar micro-reactor project on indefinite hold due to expired government funding and a lack of launch partners. The micro-reactor, designed to generate 100kW of power—sufficient for dozens of lunar homes—was seen as a critical technology to provide continuous energy during the Moon’s two-week-long nights, when solar power is ineffective. Launched three years ago with strong government backing, the project aimed to advance the UK’s position in space exploration and domestic technology but is now in limbo pending renewed support or partnerships. Meanwhile, the United States is aggressively pursuing its own lunar nuclear power initiative under an executive order signed by former President Trump, mandating deployment of a nuclear reactor on the Moon by 2030. This effort, led by NASA and the Department of Energy, is restricted to American companies to ensure national security and maintain industrial leadership, effectively excluding international players like Rolls-Roy

  • How an Influential Energy Book Became a Drag on Decarbonization - CleanTechnica

    The article critiques the continued reliance on David MacKay’s 2008 book *Sustainable Energy Without the Hot Air* as a definitive guide for energy policy in 2026, arguing that while the book was influential and valuable in its time, it no longer reflects current realities in energy systems. MacKay’s insistence on rigorous numerical analysis and physical constraints helped clarify the scale of energy challenges and the need for infrastructure to replace fossil fuels. However, his foundational approach, which anchored analysis in primary energy accounting, inadvertently exaggerated the scale of the problem by treating fossil fuel heat content as the baseline, thus underestimating the transformative potential of electrification and efficiency gains from technologies like electric vehicles and heat pumps. The article further highlights that MacKay’s assessment of renewable energy sources like solar and wind was accurate given the technology and costs of the late 2000s, but it failed to anticipate the dramatic cost reductions and performance improvements that have since occurred. By the early 2020s, solar and

  • Fujian's flaws push China towards aircraft carrier with nuclear power

    China’s latest aircraft carrier, the Fujian, represents a significant advancement as the country’s first domestically designed carrier with electromagnetic catapults and the largest conventionally powered warship globally. However, emerging technical assessments reveal critical design flaws that limit its operational effectiveness. Key issues include the island superstructure’s placement near the flight deck’s center, which reduces usable deck space and creates bottlenecks during aircraft operations. Additionally, the electromagnetic catapult arrangement intrudes into the landing area and is positioned too close to an aircraft elevator, restricting simultaneous launch and recovery operations—a capability standard on U.S. supercarriers. These layout inefficiencies, combined with a narrower and shallower angled flight deck compared to American designs, likely reduce Fujian’s sortie generation rate to about 60% of that of a U.S. Nimitz-class carrier. The identified shortcomings are largely attributed to the constraints imposed by Fujian’s conventional propulsion system, which requires large exhaust funnels and machinery spaces, limiting optimal deck and

  • China may build tugs for UK’s nuclear base, Scottish lawmaker warns

    The UK Ministry of Defence (MoD) has contracted Dutch defence manufacturer Damen, via service provider Serco, to supply 24 support vessels—including tug boats—to His Majesty’s Naval Base (HMNB) Clyde, the Royal Navy’s main base in Scotland. While the contract was competitively awarded to Serco, the company has the freedom to subcontract vessel construction without UK tendering or ministry approval. Damen’s distributed shipbuilding model often involves building smaller vessels like tugs in Asian shipyards, including those in China or Vietnam, with final fitting and integration completed in Europe. This raises security concerns given the sensitive nature of the vessels’ role in moving nuclear-powered submarines within confined waters, despite tug boats not handling nuclear material directly. Scottish lawmaker Paul Sweeney criticized the arrangement as a national security risk and a blow to UK industrial sovereignty, highlighting that UK shipyards such as Ferguson Marine could have built these vessels but were excluded due to the subcontracting process.

  • Scientists use NASA tech to detect radioactive areas in nuclear plant

    German researchers led by nuclear physicist Thomas Siegert at Julius Maximilian University of Würzburg have adapted space telescope technology to improve detection of radioactive contamination in dismantled nuclear power plants. Their project, scintLaCHARM, funded with nearly USD 2.3 million by the German Federal Ministry of Research, developed a novel method using scintillation detectors—lightweight crystals traditionally used in orbiting instruments—to map radiation more quickly, precisely, and efficiently than conventional semiconductor detectors. These conventional detectors require cooling to extremely low temperatures and scan only small areas slowly, making the decommissioning process lengthy, costly, and hazardous. The new cameras employ multiple scintillation crystals that light up upon gamma radiation exposure, allowing determination of radiation direction and energy through analysis of crystal interactions. This data, processed by supercomputers, generates detailed 3D images pinpointing contamination locations and types, enabling reliable separation of contaminated from uncontaminated materials. The technology benefits from collaboration with experts involved in NASA’s COSI gamma-ray

  • Americium: How a long-life nuclear fuel will transform space travel

    The article discusses the critical role of nuclear power sources, specifically radioisotope thermoelectric generators (RTGs) fueled by plutonium-238, in enabling long-duration space missions like the Voyager spacecraft, which have operated for nearly 50 years in deep space. Plutonium-238’s steady radioactive decay produces heat converted into electricity without moving parts, providing reliable power far from the Sun where solar energy is insufficient. Despite its effectiveness and a half-life of 88 years, plutonium-238 is scarce because it does not occur naturally and must be artificially produced in nuclear reactors, with current production rates unable to meet the growing demands of space exploration. To address this supply limitation, scientists are exploring americium-241 as a promising alternative nuclear fuel. Americium-241, first synthesized during the Manhattan Project, has a much longer half-life of 432 years, potentially enabling power sources that last for centuries rather than decades. This extended longevity could revolutionize deep space missions by supporting spacecraft

  • Video: Blue dogs roaming at Chernobyl nuclear disaster site stun all

    The article reports on the unusual sighting of blue-colored stray dogs near the Chernobyl nuclear power plant’s exclusion zone. The Dogs of Chernobyl program, initiated by the non-profit Clean Futures Fund (CFF) in 2017, aims to manage the stray dog population—estimated at over 250 animals—and provide medical care, including spaying, neutering, and vaccinations. During a sterilization effort, caretakers encountered three dogs with entirely blue fur, a phenomenon initially unexplained but later attributed to the dogs coming into contact with chemicals from a leaking portable toilet, rather than radiation exposure. The blue coloration is believed to be temporary. The Chernobyl Exclusion Zone has been largely uninhabited since the 1986 nuclear disaster, but stray dogs continue to live and reproduce there, relying on workers at the plant for survival, especially during harsh winters. These dogs face health risks such as rabies, which can also pose dangers to the caretakers. Previously, the

  • China's new heat removal method makes nuclear reactor meltdown-proof

    Chinese scientists from the China Institute of Atomic Energy have developed and successfully tested a new Residual Heat Removal (RHR) system designed to enhance the safety of next-generation nuclear reactors by preventing meltdowns. This passive heat removal technology is integrated into integral fast reactors (IFRs), which use liquid sodium as a coolant and operate with a fast neutron spectrum. The system maintains the reactor core in a safe, cool state without relying on active mechanical components, representing a significant safety breakthrough for fourth-generation nuclear plants featuring closed fuel cycles. Integral fast reactors recycle spent nuclear fuel on-site, converting unused uranium into plutonium and enabling up to 100 times more energy extraction compared to conventional water-cooled reactors. This closed-loop approach also reduces nuclear waste by approximately 90%, as continuous recycling minimizes long-lived radioactive materials. The new RHR system was validated through an experimental simulation facility that replicates reactor conditions, confirming its effectiveness in passive heat removal.

  • Massive jellyfish swarm shuts down France’s largest nuclear plant

    A massive swarm of jellyfish forced the complete shutdown of France’s largest nuclear power plant, Gravelines, located in northern France. The jellyfish clogged the plant’s cooling water intake systems, causing an automatic halt to three reactors, followed by a fourth reactor going offline, leaving the entire facility—capable of powering about 5 million homes—out of operation. Two other reactors were already offline for scheduled maintenance. EDF, the French state-owned energy company operating the plant, described the jellyfish invasion as “massive and unpredictable” but confirmed that the shutdown posed no safety risks to staff, the environment, or the public. Electricity exports from France to the UK were also unaffected. The Gravelines plant draws cooling water from a canal connected to the North Sea, where jellyfish species thrive in warmer summer waters. Jellyfish blooms, often triggered by rising sea temperatures and changing ocean currents, can overwhelm the filters at power plants, disrupting the vital flow of seawater needed to maintain reactor temperatures.

  • US: 345 MW nuclear reactor to get fast-track construction permit

    The US Nuclear Regulatory Commission (NRC) is expediting its review of TerraPower’s construction license application for the Natrium advanced nuclear reactor project, aiming to complete the safety and environmental evaluation by the end of 2025—eight months earlier than the previously scheduled August 2026. This project, backed by Bill Gates, represents the first utility-scale advanced nuclear power plant in the United States and involves building a 345-megawatt sodium-cooled fast reactor with a patented molten salt-based energy storage system in Kemmerer, Wyoming, on a retiring coal plant site. The storage technology can boost output to 500 MW when needed, and the plant is expected to be operational by 2031. The accelerated timeline is attributed to frequent collaboration between the NRC and TerraPower, though it depends on TerraPower’s timely resolution of outstanding issues. TerraPower was the first to submit a construction permit application for a commercial advanced reactor in March 2024. The NRC has already shortened the review

  • Final GOP bill kneecaps renewables and hydrogen, but lifts nuclear and geothermal

    The recently passed Republican reconciliation act, approved by a narrow 218-214 vote and awaiting President Donald Trump’s expected signature, significantly rolls back key provisions of the Inflation Reduction Act (IRA) related to clean energy incentives. The bill reduces or eliminates tax credits for solar, wind, and clean hydrogen projects, while preserving some benefits for nuclear, geothermal, and battery storage technologies through 2033. Solar and wind developers must now either connect projects to the grid by the end of 2027 or begin construction within 12 months of the bill’s passage to qualify for tax credits, tightening timelines compared to previous legislation. This shift is likely to impact sectors reliant on rapid deployment of renewable energy, such as data centers and climate tech startups, with green hydrogen companies facing particularly steep challenges as their tax credits are set to expire by 2027—five years earlier than under the IRA. While geothermal, nuclear, and battery storage incentives remain largely intact, new restrictions related to “foreign entities of concern” could

  • Beyond CATF's Biased Analysis: Why Firm Power Isn't The Full Answer - CleanTechnica

    The article critiques a recent report by the Clean Air Task Force (CATF) that argues for moving beyond Levelized Cost of Electricity (LCOE) as the sole metric for evaluating energy technologies, emphasizing the need to account for system-level integration costs of intermittent renewables like solar and wind. While the article agrees that LCOE is incomplete—ignoring costs related to storage, flexibility, transmission, and capacity value—it contends that CATF’s favored alternatives, such as nuclear power, enhanced geothermal systems (EGS), and carbon capture-equipped fossil plants, are presented with significant bias. These technologies, often labeled as ideal firm power sources by CATF, also have substantial integration challenges and costs that the report downplays or ignores. Specifically, nuclear power’s inherent inflexibility requires continuous operation at steady output to remain economically viable, necessitating costly supplementary flexibility services like pumped hydro storage to manage grid variability. Similarly, EGS depends on stable thermal reservoirs and high capacity factors, but its

  • Nvidia wants in on the nuclear renaissance, invests in Bill-Gates backed TerraPower

    Nvidia has made its first energy sector investment through its venture arm, NVentures, by participating in a funding round for TerraPower, a nuclear startup backed by Bill Gates and HD Hyundai. TerraPower is developing its Natrium reactor, designed to generate 345 megawatts of electricity, which positions it between large conventional reactors and smaller modular reactors. Unlike traditional water-cooled reactors, Natrium uses molten sodium as a coolant and incorporates a significant amount of sodium to store heat when electricity demand is low. This stored heat can then be used to generate electricity during peak demand, enabling the reactor to operate steadily while helping to balance intermittent renewable energy sources like solar and wind. TerraPower initially pursued a different reactor design but shifted to the Natrium design due to uncertainties. The company claims it can complete a reactor within three years after starting concrete work, although substantial site preparation is still required. While the Natrium reactor is expected to be cheaper than recent U.S. nuclear projects, costs remain high

  • Russia: Israel strike on Iran nuclear site risks another Chernobyl

    Russia has issued a stark warning about the potential consequences of an Israeli strike on Iran’s Bushehr nuclear power plant, cautioning that such an attack could lead to a "Chernobyl-style" nuclear disaster. The Bushehr facility, Iran’s only operational nuclear power plant, was constructed by Russia and currently employs hundreds of Russian specialists. Moscow has expressed serious concerns about the plant’s safety amid escalating hostilities between Iran and Israel, with Russian officials noting that some personnel have already been evacuated, though many remain. Russian President Vladimir Putin stated that Israel had assured Russia that Bushehr would not be targeted, but Russia’s nuclear agency Rosatom remains prepared to evacuate workers on short notice if necessary. The conflict between Iran and Israel has intensified with mutual missile and bomb attacks. Israel accused Iran of using cluster bombs—munitions that disperse smaller bomblets posing long-term risks to civilians—in a densely populated area, marking the first reported use of such weapons in this war.

  • New evidence suggests Israel’s nuclear power may be underestimated

    New evidence indicates that Israel’s nuclear arsenal may be significantly larger than previously believed, potentially comprising 200 to 300 warheads—about three times the widely accepted estimate of around 90. This reassessment is based on new analyses of Israel’s plutonium stockpile, production capacity, and satellite imagery of the Dimona nuclear facility. Experts estimate that Israel has produced between 750 and 1,110 kilograms of separated plutonium since the late 1960s, sufficient for 187 to 277 nuclear weapons depending on design. Israel maintains a policy of “nuclear ambiguity,” neither confirming nor denying its nuclear capabilities, and has historically conducted preemptive strikes to prevent regional adversaries from acquiring nuclear weapons. Amid escalating tensions with Iran, including Israel’s recent Operation Rising Lion targeting Iranian nuclear sites and Iran’s retaliatory missile and drone attacks, Israel’s nuclear capabilities have become a critical factor in regional security. Israel is believed to possess a full nuclear triad—land-based ballistic missiles (

  • German nuclear plant removes 1,200-ton generators without disassembly

    The Unterweser nuclear power plant in Germany has successfully removed four massive steam generators, each weighing approximately 300 tons and standing 20 meters tall, using an innovative heavy lift system without disassembly. Operated by PreussenElektra, the plant was notable for holding world records in power generation before its shutdown in 2011 as part of Germany’s nuclear phase-out. The steam generators were lifted out with precision and high safety standards using Mammoet’s DHS-500 handling system, which allowed for efficient removal by combining with existing cranes and hydraulic skidding, avoiding more time-consuming transport methods. Following removal, the steam generators are scheduled to be shipped to Cyclife in Sweden in July for on-site dismantling and subsequent melting. PreussenElektra is also managing the decommissioning of several other German nuclear plants and has contracted Cyclife for dismantling 16 steam generators across multiple sites.

  • Amazon announces $20B nuclear-powered data center expansion in US

    Amazon has announced a historic $20 billion investment to build two large data center complexes in Pennsylvania, marking the largest private sector investment in the state’s history. One complex is under construction near Philadelphia, while the other is planned adjacent to the Susquehanna nuclear power plant in northeastern Pennsylvania. Amazon intends to power the latter data center directly from the nuclear plant, a move that has drawn federal scrutiny and is currently under review by the Federal Energy Regulatory Commission (FERC). This direct power connection could provide Amazon with up to 960 megawatts—about 40% of the plant’s output—enough electricity to power over half a million homes, potentially at a premium price. The Pennsylvania governor, Josh Shapiro, emphasized that this investment aims to revitalize local communities and reverse the trend of young workers leaving the state for better opportunities. Amazon’s acquisition of the nearby data center and land from Talen Energy for $650 million last year enables the company to expand significantly on that site. This expansion is part of Amazon’s broader strategy, which has seen about $10 billion pledged in 2024 alone for data centers across several states, driven by the growing energy demands of AI technologies. However, the direct power deal raises concerns about grid fairness and energy access, as it may limit availability for others and bypass grid improvement fees, prompting ongoing regulatory review.
