In 2025 alone, China began construction on six new nuclear reactors, adding to an already staggering pipeline. This pipeline includes 36 reactors currently under construction, representing nearly half of all global reactor projects, according to SolarQuarter. The nation also launched two additional projects, Xuwei-1 and Taipingling-4, in early 2026, further accelerating its nuclear energy program. This aggressive build-out signifies a substantial commitment to energy infrastructure expansion, positioning China as a primary driver of global nuclear energy growth.
However, China's extensive nuclear construction contrasts sharply with its current energy reliance. While the nation is building nearly half of the world's nuclear reactors, nuclear power accounted for only 5% of its total electricity generation in 2023, according to world-nuclear. A long-term strategic investment rather than an immediate energy crisis response is highlighted by this discrepancy.
China is poised to become the undisputed global leader in nuclear energy capacity, fundamentally altering its energy mix and potentially influencing international energy policy and technology standards. This strategic expansion aims for both future energy independence and technological export dominance.
What is China's Nuclear Reactor Investment in 2026?
- China initiated construction on six new nuclear reactors in 2025 and launched two additional projects, Xuwei-1 and Taipingling-4, in early 2026, according to SolarQuarter.
- The nation currently has 36 nuclear reactors under construction, which constitutes nearly half of all reactors being built globally, according to SolarQuarter.
- As of May 2026, China operates 60 reactors across 18 sites, with a combined installed capacity of 58.7 GW, according to SolarQuarter.
- By the close of 2025, China's operational nuclear capacity reached approximately 62 GWe, according to world-nuclear, with an additional 43 GWe under construction, according to world-nuclear.
- Nuclear power contributed 5% (435 TWh) to China's total electricity generation in 2023, according to world-nuclear.
- China expects its first operational small modular reactor, the Linglong-1, to begin sending power to the grid this year, according to MIT Technology Review.
