Global nuclear capacity is set to climb 44% over the next decade after years of tepid growth, spurred by growing demand for electricity and aggressive efforts to build reactors in China and India.

The world may have as much as 535 GW of installed nuclear power by 2036, up from 372 last year, according to a report from BloombergNEF (BNEF).

The report said China had 59 GW of reactors under construction at the end of 2025 and is on track to reach a total of 102 by the end of the decade, a figure that would propel it past the US to become the world’s biggest nuclear nation.
