Nuclear Regulatory and Licensing Developments
The U.S. Nuclear Regulatory Commission achieved several historic milestones during the week, most notably approving Holtec International's request to transition the Palisades Nuclear Plant from decommissioning status back to an operating license[1]. This represents the first time a previously shut-down U.S. nuclear plant has received approval to return to operations, generating more than 800 megawatts of carbon-free baseload power capable of supplying 800,000 households[1].
President Trump's May 2025 executive orders continued to reshape nuclear licensing processes, with the NRC working to implement expedited approval timelines of less than 18 months for new reactor construction and operation licenses, and 12 months for license extensions[2]. The regulatory changes have created an "expedited pathway" for approving reactor designs previously tested by the Department of Energy or Department of Defense, with findings presumptively binding on the NRC unless explicit safety objections arise[3].
The International Atomic Energy Agency released its Nuclear Safety Review 2025, focusing on preparing safety standards for advanced reactor technologies including high-temperature gas cooled reactors and liquid metal systems[4]. Meanwhile, the NRC revised the duration of licensing design certifications from 15 years to 40 years, with Westinghouse's AP1000 among the beneficiaries[5].
Taiwan Nuclear Referendum Results
Taiwan conducted a significant nuclear power referendum on August 23, 2025, regarding the restart of the Maanshan Nuclear Power Plant's second reactor[6]. While 74.17% of voters supported restarting the plant, the referendum failed due to insufficient turnout, with only 4.34 million votes cast—falling short of the required 5 million threshold representing 25% of eligible voters[6][7].
The low turnout of 29.53% was attributed to voter fatigue following previous recall elections and the contested nature of nuclear energy in Taiwanese politics[6]. Despite the referendum's failure, President Lai acknowledged the result indicated Taiwanese desire for "diversified energy options" and suggested considering nuclear power options with reduced waste and increased safety[6].
The referendum coincided with unsuccessful recall attempts against seven opposition Kuomintang lawmakers, reflecting broader political tensions over energy policy[8]. Taiwan had become "nuclear-free" in May 2025 after shutting down the last reactor, making this vote particularly significant for the island's energy future[9].
Small Modular Reactor Advances
Small modular reactor technology demonstrated substantial progress throughout the week, with multiple design certifications and deployment announcements. NuScale Power's updated 77 MWe SMR design received standard design approval from the NRC ahead of schedule in May, marking the first such approval in recent years[10]. The company's modular approach enables configurations of 4, 6, or 12 units creating plants ranging from 308 to 924 MW[11].
TerraPower made significant strides with its Natrium demonstration project, signing a memorandum of understanding with Utah and Flagship Companies to explore reactor siting locations[12][13]. The Natrium reactor, featuring liquid sodium coolant and integrated energy storage, can boost output from 345 MW to 500 MW during peak demand periods[12]. The Wyoming Industrial Siting Council approved construction permits for non-nuclear portions of the project, with the NRC expected to complete its safety evaluation by June 2026[14].
SMR technologies are increasingly targeting artificial intelligence and data center applications, with manufacturers projecting cost reductions through series production. Current first-of-kind projects face capital costs of $3,000-6,000 per kilowatt, but these are expected to fall below conventional nuclear costs of $7,675-12,500/kW as production scales[11].
Economic and Investment Developments
Nuclear energy investment patterns reflected growing confidence in the sector's economic potential, with multiple funding announcements and economic impact studies released during the week. A Deloitte report commissioned by nucleareurope revealed that 150 GW of nuclear capacity in the European Union by 2050 would generate over €330 billion in annual economic output while supporting nearly 1.5 million jobs[15][16].
The current EU nuclear sector already contributes approximately €251 billion in annual economic output, €38 billion in disposable household income, and nearly €48 billion in public revenues while supporting 883,000 jobs across diverse skill sets[16]. These economic multiplier effects extend beyond the nuclear sector through supply chain benefits and consumer spending by nuclear workers[15].
TerraPower secured $650 million in funding featuring contributions from founder Bill Gates and Nvidia's venture capital division, expressing confidence in obtaining regulatory approval for its $4 billion nuclear reactor project[12]. The company's Natrium reactor design offers advantages for water-scarce regions by consuming significantly less water than traditional light water reactors[12].
Uranium Market and Supply Chain Dynamics
Uranium markets continued experiencing structural supply-demand imbalances, with spot prices stabilizing around $75 per pound after recovering from March lows of $63[17][18]. Current pricing levels remain insufficient to incentivize new project development, despite representing significant recovery from recent lows[19].
Consensus analyst forecasts project uranium reaching $90-100 per pound by mid-2025, potentially climbing to approximately $135 per pound by 2026[17]. Bank of America and other institutions cite accelerating reactor construction, supply constraints, and growing technology sector demand as primary price drivers[17].
Global uranium production continues meeting only 80-90% of reactor requirements, creating structural deficits increasingly filled through inventory drawdowns and spot market purchases[17]. Major supply disruptions from Kazakhstan, resource nationalism in Africa, and development timeline challenges in North America collectively suggest persistent market tightness through 2025-2026[19].
The emergence of technology companies as major nuclear electricity consumers represents a paradigm shift in demand patterns, with traditional forecasting models still adapting to incorporate these new consumption patterns effectively[17].
Environmental and Waste Management Progress
Nuclear waste management initiatives demonstrated significant progress, with Canada's Nuclear Waste Management Organization advancing public engagement for its second deep geological repository[20]. The organization released a discussion document proposing approaches for siting a repository for intermediate and non-fuel high-level radioactive waste, potentially also accommodating used fuel from future reactors[20].
International cooperation on waste management expanded, with the 2025 International High Level Radioactive Waste Management Conference scheduled for November in Washington DC under the theme "Advancing Innovative Waste Solutions for Sustainable Nuclear Energy"[21]. The conference will address storage, transportation, recycling, and disposal of spent fuel and high-level waste[21].
Finland continued developing international nuclear waste disposal capabilities, with DeepGeo responding to public consultation on legislation that would currently prohibit import and export of spent nuclear fuel for final disposal[22]. The company advocates for enabling international disposal services under strict regulatory supervision and community consent[22].
Advanced reactor designs increasingly incorporate waste reduction features, with some systems designed as "breeders" capable of producing more fissile fuel than consumed, while others enable reprocessing and recycling of spent fuel into MOX fuel suitable for existing reactors[22].
Technology and Innovation Breakthroughs
Nuclear technology innovation accelerated across multiple fronts, with advanced reactor designs moving closer to commercial deployment. Kairos Power commenced construction of the Hermes Low-Power Demonstration Reactor in Tennessee, utilizing molten salt coolant and pebble-fuel technology as alternatives to conventional water-cooled systems[10]. The company's strategic partnership with Google aims to deploy a 500 MW fleet of SMRs powering AI data centers[10].
Terrestrial Energy launched a $280 million SPAC deal, becoming the first nuclear molten salt reactor company to go public while reaching a siting agreement with Texas A&M University for its Integral Molten Salt Reactor[10]. The reactor's higher operating temperatures enable industrial heat provision alongside electricity generation[10].
Accident Tolerant Fuels entered commercial trials, while High-Assay Low-Enriched Uranium became more readily available for next-generation reactors[23]. TRISO fuel achieved commercial production milestones, with X-energy leading deployment of fuel designs that physically cannot melt even at temperatures exceeding 1,600°C[11].
The Department of Energy selected Standard Nuclear for the first pilot project in its fuel line program, aimed at eliminating American reliance on foreign enriched uranium sources[10]. Advanced fuel production capabilities in Tennessee will support emerging HALEU-based reactor designs[10].
