Billions are flowing into small modular reactors nuclear energy projects as innovators like NuScale and Amazon redefine the future of clean power.
After decades of stagnation, nuclear energy is staging a comeback — and it’s no longer the gigawatt-scale reactors of the past leading the charge.
Small modular reactors, once dismissed as niche or speculative, have moved to the center of a global energy and geopolitical pivot.
Their appeal lies in scalability, siting flexibility, and the promise of dedicated, carbon-free baseload power—a vital ingredient in an era defined by the AI energy demand surge and industrial decarbonization.
The shift from ambitious blueprints to billion-dollar commercial projects is officially underway, driven by key industry announcements throughout 2025.
