The EPP system is used to maintain the containment shell’s completeness, and control the tightness of the containment vessel and other components, maintaining tightness during the operating period of the containment vessel and during the occurrence of failures. It mainly uses computer data acquisition and processing system to monitor the containment shell’s leak status during the reactor’s normal operations and then saves and exports the relevant data.

System Characteristics

• The system’s usable lifespan is not less than 15 years.

•  Modular design.

• Self-diagnostic functions.
