New York State wants more nuclear power in a big way
New York Governor Kathy Hochul has announced plans for the state to develop a large new nuclear power facility designed to generate at least 1 gigawatt of electricity. Emphasizing the importance of nuclear energy in reducing fossil fuel dependence, Hochul directed the New York Power Authority (NYPA) to spearhead the project, though specific site and design choices remain undecided. The state intends to collaborate with private partners for development, finance construction, and purchase the plant’s output. Potential locations include existing nuclear plants in upstate New York. This initiative aligns with a broader trend of tech companies like Microsoft, Meta, and Amazon investing in nuclear power to secure clean energy for their operations. Despite renewed interest, the nuclear industry faces significant challenges, including the absence of new nuclear plant construction in the U.S. for over 15 years and historical issues with cost overruns and delays. Hochul highlighted the need for federal regulatory and permitting reforms to expedite project timelines, noting that current barriers reside primarily in Washington

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

European firms Newcleo and Nextchem have formed a joint venture, NextCleo, to develop nuclear power plants based on Newcleo’s 200 MW lead-cooled fast reactor (LFR-AS-200) modular technology. Newcleo will focus on developing the nuclear reactor itself, while Nextchem will provide expertise in designing and managing the conventional island and balance of plant components necessary to convert nuclear energy into dispatchable electric power. Nextcleo will also offer integration services to other small modular reactor (SMR) and advanced modular reactor (AMR) technology providers. This collaboration aims to support decarbonization efforts, particularly by enabling low-carbon chemical production aligned with Nextchem’s e-Factory model. Nextchem will hold a 60% stake in Nextcleo, retaining operational control, while Newcleo will own 40%. Additionally, Nextchem will acquire an initial minority stake in Newcleo, increasing upon development milestones. The partnership plans to have a non-nuclear precursor prototype ready by 2026

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. Iranian missile

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 (

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. The successful use of the DHS-500 system at Unterweser, building on prior experience

Amazon has joined a growing trend among major tech companies by securing 1.92 gigawatts of electricity from Talen Energy’s Susquehanna nuclear power plant in Pennsylvania to power its AWS cloud and AI servers. Unlike an earlier plan where Amazon intended to build a data center adjacent to the plant and draw power directly—bypassing the grid and transmission fees—regulatory concerns led to a revised agreement. The current deal positions Amazon as a grid-connected customer, paying transmission fees like other users, with the arrangement set to last through 2042. Transmission infrastructure upgrades are planned for spring 2026 to support this setup. Beyond the power purchase, Amazon and Talen Energy plan to explore building small modular reactors (SMRs) within Talen’s Pennsylvania footprint and expanding output at existing nuclear plants. Such expansions typically involve optimizing fuel enrichment, turbine upgrades, or other modifications to increase power generation. This move aligns Amazon with peers like Microsoft and Meta, who have also made significant investments in nuclear

Russian state nuclear corporation Rosatom has initiated the pilot operation of fifth-generation (Gen-V) nuclear fuel assemblies, designated TVS-5, by loading them into the VVER-1200 reactor core at the Novovoronezh Nuclear Power Plant (NPP). Manufactured by the Novosibirsk Chemical Concentrates Plant, these fuel bundles are designed for fully automated fabrication, enabling industrial-scale production critical for advancing a closed nuclear fuel cycle. The pilot phase will span three 18-month fuel cycles, using a regular enriched uranium dioxide fuel matrix under strict regulatory oversight by Rostechnadzor. This development marks a significant milestone in Russia’s strategic shift toward a dual-component nuclear power system that integrates thermal and fast neutron reactors with a closed fuel cycle. The closed cycle aims to reuse spent nuclear fuel by reprocessing uranium and plutonium, thereby improving resource efficiency and sustainability in nuclear power generation. Rosatom emphasizes that the TVS-5 fuel design and its automated manufacturing process are essential steps toward enabling the

Rolls-Royce has been selected by the UK government and the state-owned Great British Energy – Nuclear as the preferred bidder to develop the country’s first fleet of Small Modular Reactors (SMRs). The project aims to generate 1.5 gigawatts (GW) of electricity, enough to power approximately 3 million homes. Unlike traditional nuclear plants built entirely on-site, these SMRs will be factory-manufactured in modules and then assembled at the final location, a method intended to reduce construction costs, complexity, and delays. Each Rolls-Royce SMR will produce 470 megawatts, with the technology expected to begin generating power by 2032 at the earliest. This initiative is part of a broader UK nuclear strategy that includes a £14.2 billion investment in the large Sizewell C power station and a £2.5 billion commitment to the SMR program during the current Spending Review period. The government highlights that SMRs are smaller, quicker to build,

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.

Florida-based Holtec International, in partnership with Hyundai Engineering & Construction, plans to deploy advanced small modular reactors (SMRs) at the retired Palisades nuclear plant site in Michigan by 2030. The project, part of Holtec’s “Mission 2030” program, aims to build America’s first SMR-300 units—each a 300 MW advanced, passively safe, pressurized light water reactor—co-located with the existing 800 MW Palisades plant, which is currently being restarted after its 2022 shutdown. Holtec intends to build a 10-gigawatt fleet of SMR-300s across North America during the 2030s, leveraging the cost advantages of deploying SMRs at existing nuclear sites. Holtec is also exploring additional SMR deployments, including up to four units at the Oyster Creek site in New Jersey, where a 625 MW boiling water reactor is slated for decommissioning by 2029. The company sees significant growth potential for SMRs in the Mountain West region, particularly in Utah and Wyoming, supported by ongoing testing at Idaho National Laboratory and recent pro-nuclear legislation in Utah. Holtec’s SMR-300 design emphasizes passive safety features, such as gravity-driven safety systems, earning it a “walk-away safe” designation, and positions the company to compete globally against state-backed reactor vendors by offering comprehensive lifecycle services from construction to decommissioning. The Palisades SMR-300 project is intended to serve as a global benchmark for next-generation nuclear technology deployment, advancing U.S. leadership in clean energy innovation and unlocking worldwide opportunities for SMR adoption. Holtec highlights the project’s role in providing clean, reliable energy capable of powering hundreds of thousands of homes while maintaining high safety and operational standards.
