These Countries Are Building The Most Small Modular Nuclear Reactors
The U.S. is leading the world in small modular nuclear reactor (SMR) development with 28 siting announcements, as of 2026.
This graphic, via Visual Capitalist's Cody Good, in partnership with the National Public Utilities Council, shows which countries are building the most SMRs.
The U.S. Leads Global SMR Development
With 28 siting announcements, the U.S. has more SMR projects in development than the next four countries combined.

Only 78 of 129 SMR designs being tracked by the NEA are publicly reported in the digital dashboard. The rest have either requested not to be included or are not under active development.
Across the U.S., national laboratories lead in siting announcements (7), followed by a three-way tie among utilities, universities, and SMR developers (5 each).
Why Small Modular Reactors Matter
SMRs are a critical clean-energy technology that are cheaper and more flexible than traditional nuclear power generation.
- Small: SMRs can produce up to 300 MWe, far less than traditional reactors, which typically produce around 1,000–1,400 MWe.
- Modular: SMRs are designed for mass factory manufacturing to reduce cost and build time.
- Reactor: The four main reactor types are light water reactors, fast neutron reactors, graphite-moderated high temperature reactors, and molten salt reactors.
Their compact, modular design enables easier transport and deployment ideal for data centers or remote sites where grid connection is costly or unnecessary.
The Role of SMRs in the Future of Power
As electricity demand accelerates, SMRs are becoming an increasingly important part of conversations around grid reliability, energy security, and clean firm power.
For utilities and policymakers, tracking where these projects are emerging can help inform planning, policy, and long-term strategy.

- • The United States leads the world in Small Modular Reactor development with 28 siting announcements.
- • SMRs offer cheaper, more flexible, and modular energy solutions compared to traditional large scale reactors.
- • Global competition is intensifying with Canada, the United Kingdom, Russia, and China also advancing nuclear technologies.
The surge in SMR development is driven by rising electricity demand from data centers and the need for grid reliability. The U.S. government is supporting this through the Advanced Reactor Demonstration Program with billions in federal funding.
Christian Perspective
Energy independence is a prerequisite for a stable, God honoring society that can sustain its families and communities. Controlling the means of production through advanced technology allows a nation to steward its resources without relying on hostile foreign powers. Reliable power is essential for the infrastructure that supports Christian life and traditional social order.
Implications
Dominance in nuclear technology secures American sovereignty and protects the nation from the volatility of globalist energy markets. This technological edge supports the growth of domestic industries and the stability of the American home. Energy security ensures that the biological and cultural continuity of the nation is not compromised by external energy blackmail.
Broader Trends
The race for SMRs reflects a shift toward nationalistic competition between major powers like the U.S., Russia, and China. It highlights the move away from unreliable green energy mandates toward firm, reliable power sources. This trend aligns with a broader push for national self sufficiency and the rejection of globalist environmental agendas.
Takeaway
America must aggressively pursue nuclear dominance to ensure the survival and strength of the nation. We must prioritize energy security as a pillar of the America First agenda to protect our people and our way of life. True sovereignty requires the power to fuel our own civilization on our own terms.
