Containment System FunctionsContainment System Functions
Containment System functions include:Protection of reactor, spent fuel, and safety related SSCs from external loads and missilesProtection of the reactor, spent fuel, and safety related SSCs from high energy HPB breaks and other internal hazards (e.g. fires and floods)Mitigation of fission product releases via vented and filtered confinement approachLimit air ingress to the MPS following a HPB breachAdditional functions to support access, maintenance, personnel safety, and health physics

Specialized DoorsSpecialized Doors
The functions of the Specialized Doors include:Facilitate access to reactor building areas
Support building confinement functions – Limit air ingress into the Citadel, post event, for HPB breaks
– Limit the release of fission products to atmosphere
Support zoning within reactor building – Fire
– Flood
– PRS pressure
– HVAC static pressure zones
– Radiation protection

Conventional Island (Generator House)Conventional Island (Generator House)
The Generator House performs the following primary functions:
Provides access to the generator during operation and maintenanceHouses the ancillary plant serving the generator, e.g. breaker, SFCHouses the generator transformer and unit transformer bussbarsHouses the two redundant trains of electrical systems interfacing with the Nuclear IslandHouses the two lube oil systems serving the turbine, compressors and generator in the controlled and non-controlled areas
