AI Accelerates Nuclear Renaissance — Number of Nuclear Power Plants Under Construction Hits 40-Year High
According to the World Nuclear Association (WNA), 79 nuclear reactors are currently being built worldwide — the highest number in four decades. Another 122 projects are planned, with over 300 considered prospective.

As of October 16, 2026, 79 reactors are simultaneously under construction in various countries. The expansion of these plans is driven by the electricity demands of data centers and AI, as well as rising fossil fuel prices.
For projects to transition into the construction phase, financing, licensing, and a ready industrial base will be required.
Nuclear energy is returning to the agenda in Europe and Japan. France is considering the construction of 14 reactors, while Japan plans to build 11–14 new power units.
