US Approves First Small Modular Reactor at Clinch River
The U.S. Nuclear Regulatory Commission (NRC) has granted Tennessee Valley Authority (TVA) a construction permit for the first small modular reactor (SMR) in the United States, the GE Vernova Hitachi BWRX-300, at the Clinch River site in Oak Ridge, Tennessee. The permit was issued 14 months after application, four months ahead of schedule. The 300 MW reactor will power about 300,000 homes, with commercial operation planned for the early 2030s. The U.S. Department of Energy is supporting the project with $400 million. The reactor aims to meet electricity demand from AI data centers, projected to consume 12% of U.S. power by 2030. Critics argue SMRs remain too expensive and slow, citing the cancellation of a NuScale project and higher-than-expected costs for Canada's first BWRX-300.
This news is relevant to the AdTech/MarTech industry only tangentially, as it relates to energy infrastructure for AI data centers. The primary focus is on nuclear power regulation, which is not directly an advertising technology or marketing technology topic. However, the growth of AI data centers is a significant driver for the digital advertising ecosystem, making this indirectly relevant.

Italy Passes Nuclear Return Law, SMR Companies Pounce
Italy's parliament has approved a framework law ending a nearly 40-year ban on nuclear power, clearing the way for the government to set regulations by decree. Companies are already positioning: Terra Innovatum, a Nasdaq-listed microreactor developer, plans to enter the Italian market with its SOLO reactor, targeting data centers and industrial sites. Italian industrial groups Enel, Ansaldo Energia, and Leonardo formed the Nuclitalia joint venture, while Newcleo, a French-based startup, is seen as a government-favored partner. The law also covers safety, spent fuel, and hydrogen production. However, challenges remain, including commercial viability, high costs, a lack of a waste repository, and a recent $30 billion drop in SMR sector market value. The first plants could come online by 2033-2034.
Race to Power the Grid by 2035 Widens
Tech companies' growing AI compute needs are driving investment and commercial deals across fusion, small modular fission, natural gas, and long-duration battery storage as contenders to supply reliable 24/7 power by 2035. Natural gas remains the current baseload choice but faces supply-chain vulnerabilities and multi-year turbine backlogs. Several small modular reactor (SMR) firms and fusion startups aim to connect commercial plants to grids in the early 2030s; notable projects include Kairos Power's Hermes 2 demo, Oklo's 2028 target, Commonwealth Fusion Systems' demo and 400 MW Arc, and Helion's aggressive plan to deliver electricity to Microsoft by 2028 and to supply OpenAI at multi-gigawatt scale by 2030–2035. Cost and scale remain key hurdles: current levelized costs for new nuclear and fusion are high versus gas and renewables paired with batteries, while new long-duration storage (iron‑air, organic fluid designs) could undercut alternatives.
Nuclear Startup Bluecore Energy Raises $50M Seed Round
Bluecore Energy, a startup building small modular reactors on floating barges, announced an oversubscribed $50 million seed round just two months after emerging from stealth. The company, founded by Kofi Asante, previously raised a $10 million pre-seed round. The seed round was led by Silverton Partners, with participation from existing investors Slauson & Co., Harlem Capital, and Ripple co-founder Chris Larsen, as well as new investors such as Collab Capital and Kevin Hart's Hartbeat Ventures. The funding will support product development, regulatory work, nuclear fuel purchases, and hiring. Bluecore Energy, headquartered at the Port of Long Beach, is undergoing design review with the Nuclear Regulatory Commission and Coast Guard, and has seen interest from ports, AI data centers, and communities seeking clean energy.
