The following table was developed using the current Model of Record (MOR), which is documented in the Peach Bottom Atomic Power Station (PBAPS) PRA Summary Notebook (PB-PRA-013, Revision 4). The table was developed using the EPRI R&R Workstation SysImp Computer code. It shows the top systems/groups of equipment to the overall CDF by Fussell-Vesely.
SYSIMP Key System/Equipment Contribution to CDF System/Equipment Tag F-V High Pressure Coolant Injection HPCI 15.8%
Condenser Vacuum TCV 11.8%
Reactor Core Isolation Cooling RCIC 10.9%
Emergency Diesel Generators EDG 7.9%
Reactor Protection System RPS 5.7%
High Pressure Service Water HPSW 4.8%
Main Steam Isolation Valves MSIV 3.8%
Emergency Cooling Tower/
Emergency Cooling Water ECT/ECW 2.2%
