Small Modular Reactor
A nuclear reactor design concept in which individual units typically produce less than 300 megawatts of electrical output. These reactors can be factory-fabricated and transported to installation sites, offering advantages including shorter construction timelines, lower costs, and enhanced safety characteristics compared to conventional large-scale reactors.

Timeline (last 90 days)
Currently multiple SMR projects worldwide are in the design certification or demonstration construction stage, and commercially operating cases remain limited.
Currently dozens of SMR designs worldwide are at different stages of development, and some have entered the regulatory approval process, but there is still a distance to large-scale commercial deployment, with the main bottlenecks being adaptation of the regulatory framework, validation of economics, and maturity of the supply chain.
Off-grid self-generation options for AI data centers include gas turbines, small modular reactors (SMRs), geothermal power, and restarting decommissioned nuclear power plants.
The combined narrative of AI and clean energy has spawned a batch of dedicated funds focused on nuclear power restarts, small modular reactors (SMRs), and associated energy storage projects.
Multiple countries around the world are currently in the approval and pilot stages for SMRs, including the United States, the United Kingdom, Canada, and Poland.
The cost advantage of SMRs at commercial scale has yet to be fully validated, and some SMR projects that have been greenlit have run into difficulties due to costs exceeding expectations.
Small and medium modular reactors (SMRs) generally refer to nuclear power units with a single-unit capacity below 300 MW.
The variables that will determine whether data center natural gas consumption forecasts come true include the deployment speed of renewable energy and energy storage, the commercialization progress of new power sources such as SMRs, and the extent of improvements in AI model energy efficiency.
Google and Amazon have successively reached power purchase agreements with SMR startups.
Floating reactors generally refer to small modular nuclear energy solutions deployed offshore or on water surfaces.
