Together, these developments are ushering in a new era of agile, factory-built reactors that can be tailored to a diverse range of applications, from remote microgrids to decentralized data center power supplies.

Moreover, government action has been pivotal in catalyzing market momentum. In accordance with Executive Order 14154 on streamlining regulatory pathways, the Nuclear Regulatory Commission has established high-volume microreactor licensing processes that prioritize designs already vetted by the Department of Defense or Department of Energy. Complementing regulatory reform, the ADVANCE Act introduces licensing cost reductions and prize incentives to accelerate the deployment of next-generation reactor technologies, including dedicated support for Brownfield repowering and microreactor demonstration projects. These combined measures are dismantling historical barriers to entry, setting the stage for a proliferation of small reactor applications across critical infrastructure sectors.

United States tariff policy has emerged as a critical factor influencing global supply chains for small nuclear reactor components. Proposed tariffs of up to 10 percent on Canadian‐sourced uranium pose challenges to fuel procurement, with Canada supplying the majority of uranium feedstock for U.S. reactors. Higher uranium prices could elevate operational costs and incentivize the development of domestic enrichment capabilities, although significant capital requirements and environmental reviews remain formidable obstacles.

Simultaneously, the U.S. Department of Commerce has suspended export licenses for American nuclear equipment suppliers targeting Chinese markets, disrupting long‐standing supply relationships for reactor pressure vessels, control systems, and specialized alloys. This strategic move, part of broader export controls imposed in mid‐2025, is expected to prompt North American manufacturers to diversify their client base and pursue alternative export destinations to mitigate revenue impacts.

Furthermore, retaliatory measures from foreign partners, such as China’s export curbs on critical reactor materials like yttrium and chromium, underscore the importance of resilient supply networks. Companies are exploring near-shoring and dual sourcing strategies to absorb tariff-induced cost pressures, while policymakers are assessing tariff exemptions for key nuclear inputs to preserve the competitiveness of domestic small reactor projects.

Analysis of reactor types reveals that fast reactors, encompassing gas cooled fast, lead cooled, and sodium cooled designs, are poised to address industrial heat and waste transmutation needs, while high temperature gas cooled systems such as pebble bed and prismatic reactors offer high‐efficiency thermal output suited for hydrogen production. Light water reactors remain a proven baseline technology, complemented by molten salt variants using chloride and fluoride salts that enable intrinsic safety features and online refueling.

Examining end‐use applications, desalination plants leveraging multi-stage flash and reverse osmosis are demonstrating compact reactor integration, and district heating schemes at both campus and urban grid scale benefit from steady, high-temperature heat output. Electricity generation is bifurcated into grid-tied and off‐grid units, with microreactor form factors supporting isolated communities and industrial process heat applications such as food processing, petrochemical refining, and heavy manufacturing.

Power output tiers offer tailored solutions: under ten MWe units serve critical remote operations, ten to fifty MWe systems address mid-scale industrial and community demands, and fifty to three hundred MWe modules deliver utility-grade capacity. Coolant selection between gas, liquid metal, molten salt, and water platforms informs thermal characteristics, with each medium-ranging from carbon dioxide and helium to sodium, lead bismuth, chloride salt, boiling water, and pressurized water-presenting unique operational profiles.

End‐user segmentation spans commercial installations such as data centers and hospitals, government deployments for military and research applications, industrial facilities in manufacturing and oil and gas sectors, and traditional utilities seeking grid modernization. Fuel considerations include mixed oxide and thorium alternatives, alongside enriched and natural uranium, each driving distinct fuel cycle strategies. Construction models vary between factory assembled modules and field assembled modules, and ownership frameworks encompass build-own-operate, build-own-operate-transfer, engineering-procurement-construction, and self-build arrangements. Finally, site selection strategies leverage both brownfield sites for coal plant repowering and greenfield locations for new installations.
