The joint venture model ensures that both the national nuclear operator and the regional investor have aligned interests in maintaining high operational standards to support these broader strategic objectives.
Reactor Design and Technology
The Fangchenggang Nuclear Power Plant utilizes two distinct nuclear reactor designs, reflecting the evolution of China’s domestic nuclear technology. Units 1 and 2 are equipped with CPR-1000 reactors, a third-generation pressurized water reactor (PWR) design. This technology represents a standardized, mature platform that has been widely deployed across China’s coastal nuclear fleet, offering proven operational reliability and a streamlined supply chain. The CPR-1000 incorporates passive safety features and digital instrumentation, serving as a foundational step in the country’s nuclear expansion strategy.
Units 3 through 6 utilize the Hualong One (HPR-1000) reactor design. The Hualong One is a newer, third-generation+ PWR that integrates advanced safety systems, including dual containment structures and both active and passive heat removal mechanisms. This design is notable for its enhanced seismic resilience and modular construction capabilities. Units 5 and 6 are also planned to be Hualong One reactors, ensuring technological consistency in the latter stages of the plant’s development.
Reactor Specifications Comparison
| Parameter | CPR-1000 (Units 1–2) | Hualong One (Units 3–6) |
|---|---|---|
| Reactor Type | Pressurized Water Reactor (PWR) | Pressurized Water Reactor (PWR) |
| Generation Class | Generation III | Generation III+ |
| Primary Safety Features | Passive safety systems, digital I&C | Dual containment, active/passive heat removal |
| Strategic Role | Domestic standardization | Export reference (e.g., Bradwell B) |
| Planned Units | 2 | 4 |
The transition from CPR-1000 to Hualong One at Fangchenggang illustrates a strategic shift toward more advanced, export-ready technology. While the CPR-1000 provides immediate capacity with established performance metrics, the Hualong One offers improved safety margins and modular efficiency, positioning the plant as a showcase for China’s next-generation nuclear capabilities. Both designs rely on uranium fuel and contribute to the plant’s total operational status and capacity goals.
