Construction of Unit 2 of the Phase I expansion project at China's Huaneng Shidao Bay Nuclear Power Base officially began on Wednesday, marking the project's entry into the full-scale construction phase.

The Phase I expansion will add two new units to the base. Construction of Unit 1 began in July 2024. Unit 2 will feature the domestically developed third-generation nuclear reactor, Hualong-1, with a maximum capacity of 1.2 million kilowatts and an expected annual output of 10 billion kilowatt-hours. In addition to electricity, the base will also provide nuclear-generated heat. The Phase I expansion project is expected to add over 20 million square meters of heating coverage, benefiting 600,000 local residents.
