Including Safety Condenser (SACO) and Containment Wall Condenser (CWC) to future generations of nuclear power plant (NPP) are possible options to potentially increase safety and resilience during a Station Blackout (SBO) given that they do not need any external electrical power supply to operate. Furthermore, passive systems can provide an interesting alternative to active systems in terms of capital installation and maintenance costs. Several sources agree that the introduction of innovative passive systems significantly lower the core damage frequency (CDF) of nuclear power plants.
