Safety Features and Containment
The CPR-1000 and ACPR-1000 reactors at Hongyanhe incorporate advanced passive and active safety systems designed to mitigate risks associated with both internal and external events. A key safety feature is the double containment structure, which consists of an inner steel liner and an outer concrete shell. This design provides robust protection against external impacts, such as aircraft crashes or seismic activity, while maintaining pressure integrity during steam blowdown events.
Additionally, the reactor designs include a core catcher, a specialized structure located beneath the reactor pressure vessel. In the event of a severe accident leading to core melt, the core catcher spreads and cools the molten fuel, preventing it from penetrating the containment floor and reaching the underlying bedrock. This feature is critical for long-term containment integrity and radiation leakage control. The integration of these safety mechanisms aligns with international nuclear safety standards, ensuring reliable operation in the Donggang Town site.
