China is pulling dramatically ahead of the rest of the world in building new nuclear power plants, with 39 reactors currently under construction, more than the next 12 countries put together, according to Kobeissi. India and Russia follow with just 8 and 7 respectively, each under half of China's total. China is also building far faster: its reactors under construction have been underway for an average of only about 2.8 years, versus a global average of 5.8 years that is dragged down by chronically delayed projects like India's 22 year build and Brazil's 16 year build. The United States, by contrast, currently has no large commercial nuclear reactors under construction at all. The buildout fits a broader pattern where Beijing treats energy infrastructure as a strategic asset to be scaled quickly rather than a slow, permit heavy undertaking, and it is happening as global electricity demand from AI data centers and electrification pushes utilities everywhere to look for reliable, always on power sources. A pipeline this size, if it keeps its pace, would give China outsized influence over uranium demand, reactor technology exports and the broader nuclear supply chain for years to come, at a time when the West is still debating whether and how fast to restart its own nuclear build cycle.
Why it matters · A nuclear buildout this lopsided points to who will control uranium demand and reactor exports for the next decade, and it underscores how much slower the West has been to treat baseload power as urgent even as AI driven electricity demand keeps climbing.
Worth asking · If China keeps building reactors at this pace while the US has none under construction, does the West eventually have to fast track its own nuclear restart, or will renewables and gas fill the gap instead?
