Construction of Access Tunnels Commences for Phase III of Taipingling Nuclear Power Project

On August 26, 2026, CGN's Guangdong Taipingling Nuclear Power Plant held a mobilization meeting for the construction of its Phase III project. At the meeting, the "Safety and Quality Responsibility Agreement for the Construction and Operation of CGN Guangdong Taipingling Nuclear Power Plant Phase III Project" was unveiled, aiming to further consolidate safety and quality responsibilities in nuclear power engineering construction, strengthen project quality management, and ensure the safe and orderly progress of project construction.

At the mobilization meeting, Zhang Guoqiang, Secretary of the Party Committee and Chairman of CGN Huizhou Nuclear Power Co., Ltd., announced the official commencement of access tunnel construction for the Phase III project. Upon completion of the access tunnel construction, it will help improve the organizational efficiency of project construction in areas such as material transportation and module hoisting, and create conditions for the subsequent pouring of the first batch of nuclear island concrete and continuous construction.

The Phase III project of Taipingling Nuclear Power was reviewed and approved at the executive meeting of the State Council on July 31, 2026, and received formal approval. This project is the first nuclear power project in the Guangdong-Hong Kong-Macao Greater Bay Area to adopt the "Hualong One" 2.0 technology solution. The "Hualong One" 2.0 is an independent third-generation nuclear power technology solution further iterated from "Hualong One" 1.0, continuing the mature technical architecture of the 177-core reactor and three-loop design, while optimizing and upgrading the active-passive coupled safety system and the enhanced containment structure.

According to reports, this technology solution features strong seismic resistance and resistance to large commercial aircraft impact, and can operate for 72 hours without operator intervention. Through system scheme optimization and the application of advanced construction technologies, the project construction period, cost, and overall engineering economics will also be further optimized.

The Phase III project of Taipingling Nuclear Power plans to build 2 units, each with a rated power output of approximately 1,200 megawatts, with the capability of 100% domestically manufactured equipment. Based on the average annual utilization hours of domestic nuclear power in 2025, the project is expected to generate more than 17 billion kilowatt-hours of electricity annually after commissioning, which can meet the annual production and living electricity needs of nearly 2 million people.
