Bailong 2 Nuclear Unit Begins Construction with First Concrete Pour
The Bailong nuclear power plant, located in the Guangxi Zhuang Autonomous Region of southern China, has officially begun construction on its second unit, Bailong 2. The first concrete for the unit was poured on December 22, 2025, marking the start of its construction phase. This development means that two units at the Bailong site are now under active construction.
The construction of Phase I, comprising units 1 and 2 of the Bailong plant, received approval from China's State Council in August 2024. State Power Investment Corporation is developing these two CAP1000 pressurized water reactors, which are the Chinese variant of the Westinghouse AP1000 design. The total investment for these two units is estimated at CNY40 billion (USD5.6 billion), with a projected construction period of 56 months.
The initial concrete pour for Bailong 2 involved 6,662 cubic meters of concrete and lasted just over 64 hours. This follows the excavation work for the foundation pit of unit 1's nuclear island, which began in late December 2024. Shanghai Nuclear Engineering Research & Design Institute (SNERDI), a subsidiary of State Power Investment Corporation and a joint general contractor for the project, announced the completion of this critical step.
The Bailong plant, situated on Jiangshan Peninsula in Fangchenggang City, Guangxi Province, is planned to eventually host six units. The total installed capacity for the entire plant is projected to be 8.62 GWe, with an overall investment of approximately CNY120 billion. Each unit in the first phase, utilizing the CAP1000 design, will have a capacity of 1.25 GW. Future phases propose the construction of four larger CAP1400 reactors at the site.
Upon completion and operation, the first phase of the Bailong project is anticipated to generate approximately 20 billion kilowatt-hours of electricity annually. This output is equivalent to an annual reduction of about 6 million tonnes in standard coal consumption and approximately 16 million tonnes in carbon dioxide emissions.
