April 28, 2025 — In a significant move to expand its nuclear energy infrastructure, China has approved the construction of ten new nuclear reactors, marking the fourth consecutive year of similar approvals. This latest development aligns with the country’s ambitious energy goals as it aims to become the world’s largest producer of nuclear energy by 2030.

With 30 nuclear reactors currently under construction—almost half of the global total—China is intensifying efforts to meet its growing energy demands while transitioning towards cleaner energy sources.

$27 Billion Investment in New Nuclear Plants

The new reactors, which are expected to cost 200 billion yuan ($27 billion) in total, have been allocated to China National Nuclear Corporation (CNNC), State Power Investment, and China Huaneng Group. Specifically, four reactors have been assigned to CNNC for its Fangchenggang and Taishan plants, while other groups are each responsible for two reactors.

By 2025, China’s nuclear capacity is projected to reach 65GW, an increase from the previous year’s less than 60GW. As part of its broader energy strategy, China is targeting 200GW of nuclear capacity by 2040, which is expected to contribute 10% of the nation’s total electricity generation.

Pioneering New Technologies in Nuclear Energy

China’s nuclear energy capabilities are also advancing technologically. In 2023, the country launched its inaugural commercial fourth-generation nuclear reactor, the Shidao Bay high-temperature gas-cooled reactor (HTGR), which uses helium instead of water for cooling and electricity generation. This marks China’s commitment to developing cutting-edge nuclear energy technologies.

The government has also approved the phase three expansion of the Sanmen nuclear power plant in Zhejiang province, further cementing the country’s focus on nuclear energy as a key pillar of its clean energy future.

Nuclear Energy Growth and Clean Energy Milestones

In the first quarter of 2025, China achieved a new record for clean electricity generation, producing over 951 terawatt hours (TWh). Notably, nuclear energy saw a 13% increase, contributing 117TWh to the total, according to the energy think tank Ember.

These developments underline China’s ongoing push towards increasing its share of clean and sustainable energy sources, with nuclear power playing a crucial role in meeting the country’s energy needs and its environmental commitments.
