Technological Shift: From AP1000 to Hualong One
A notable aspect of the Taipingling project is the strategic shift in reactor technology. Originally, China General Nuclear Power Group planned to utilize AP1000 light water reactors for the station. However, the plans were later revised to adopt the Hualong One design. This transition reflects broader trends in China’s nuclear program, where domestic technology development has gained prominence alongside international partnerships. The Hualong One, a third-generation pressurized water reactor, represents a significant milestone in China’s efforts to standardize and export its nuclear technology. By selecting Hualong One for Taipingling, CGN demonstrates confidence in the domestic design’s reliability, efficiency, and competitive advantage in the global nuclear market.
Regional Energy Impact
The commissioning of Taipingling in 2026 will enhance the energy security of Guangdong Province, one of China’s most industrialized and populous regions. As a major new nuclear project, the plant will provide a stable baseload power supply, complementing variable renewable sources such as wind and solar. The use of uranium as the primary fuel source aligns with the plant’s classification as a nuclear power station, ensuring a low-carbon energy output that supports China’s broader climate goals. The facility’s coastal location in Huizhou also facilitates cooling water access, a critical factor for thermal efficiency in nuclear operations. Overall, Taipingling’s development highlights the continued importance of nuclear power in China’s energy transition strategy, balancing technological innovation with regional energy needs.
What is the history of the Taipingling Nuclear Power Plant?
The development of the Taipingling Nuclear Power Plant involved a significant strategic shift in reactor technology selection during its planning phase. The facility is located in Huangbu Town, Huidong County, within Huizhou city on the coast of Guangdong Province in southeast China.
Initially, the project was designed around the AP1000 light water reactor technology. This design choice reflected early strategic partnerships and technology transfer agreements common in China's nuclear expansion during the preceding decade. However, as the project progressed, the ownership group revised its technical specifications. The decision was made to switch from the AP1000 design to the Hualong One reactor model. This change aligned the Taipingling project with other recent Chinese nuclear developments that favored the domestically developed Hualong One standard, which combines features from both the ACPR1000+ and the AP1000 designs.
Key regulatory milestones for the project include approval dates in 2019 and 2023. The 2019 approval likely pertained to the initial site selection and early engineering phases, while the 2023 approval marked a critical step toward full-scale construction, possibly confirming the final reactor design choice and financial structuring. These approvals were necessary to transition the plant from the planning stage to the "under construction" status it currently holds.
As of 2026, the plant is scheduled for commissioning. The construction phase has seen steady progress, leveraging the established supply chain for Hualong One components. The switch to Hualong One required adjustments to the civil works and mechanical installation schedules, but the overall timeline remained targeted for a 2026 start of operations. The plant's location in Guangdong Province positions it to serve the growing energy demand in southeast China, contributing to the region's grid stability with uranium-fueled nuclear power.
How does the Hualong One design work?
The Taipingling Nuclear Power Plant was originally planned to utilize AP1000 light water reactors, but the operator, China General Nuclear Power Group, later changed plans to the Hualong One design. This shift represents a strategic move toward a domestically developed reactor technology, contrasting with the imported Westinghouse-derived AP1000. The Hualong One is a Generation III+ pressurized water reactor (PWR) that incorporates both active and passive safety systems, aiming to enhance reliability and reduce reliance on external power during accidents.
Key Design Features of Hualong One
The Hualong One design integrates safety features from two earlier Chinese reactor programs: the CPR-1000 and the ACPR-1000. It features a 177-fuel-assembly core, which increases the thermal margin compared to the 157-assembly core of the AP1000. The reactor utilizes a double-containment structure with a spherical inner steel containment vessel and a cylindrical outer concrete shell, providing robust protection against external impacts and internal pressure loads.
| Feature | Hualong One | AP1000 (Originally Planned) |
|---|---|---|
| Reactor Type | Pressurized Water Reactor (PWR) | Economic Passive Advanced PWR |
| Core Assemblies | 177 | 157 |
| Containment | Double (Steel + Concrete) | Single (Steel + Concrete) |
| Primary Safety Systems | Active and Passive | Primarily Passive |
| Origin | China (CGN/SPIC) | USA (Westinghouse) |
The Hualong One employs a combination of active safety systems, such as feedwater pumps and residual heat removal, alongside passive systems like natural circulation cooling and gravity-driven core flood tanks. This hybrid approach ensures redundancy and diversity in safety mechanisms. In contrast, the AP1000 relies more heavily on passive safety features, such as natural convection and gravity, to cool the core during a loss-of-coolant accident. The decision to switch to Hualong One for Taipingling may reflect considerations of supply chain resilience, technological sovereignty, or specific site conditions in Huangbu Town, Huidong County, Huizhou city on the coast of Guangdong Province, in southeast China. The plant is owned by CGN Huizhou Nuclear Power Co. and is scheduled for commissioning in 2026.
