FNP Fire Protection o Introduction FNP - Two 900 MWe 3 loop Westinghouse PWR Units Committed to 10CFR 50 App R.
The FNP fire protection program provides defense-in-depth protection:
Design Features Personnel Training Fire Fighting Equipment Operating Procedures
NRC Screening Criteria Criteria Applies to Reason/Info FNP Large Number of Operator Yes*
FNP is estimated to have significantly less than Actions BFN but more than the other SNC plants.
Single Fire can effect more No*
Fire areas/equipment relied upon for App R safe than one Unit.
shutdown are not common. Shared DG's can be impacted. DG redundancy ensures SSD.
Use of Thermoplastic Cables Not Some thermoplastic used for low voltage Significant*
applications such as cameras or telecommunications. Less than 8 % of cables installed.
Problems documenting cable No No significant issues with documenting cable routing routing.
Ana lysis Credits Self Induced No SISBO not credited Station Blackouts Complicated Manual Operator Yes
- Based on NRC criteria. Current manual actions are Actions felt to be reasonable. Operators are trained and drilled on actions. Compensatory actions in place.
Mitigation of a fire requ ires Not No electrical cross connections credited. Limited the use of systems from Significant use of cross connected air systems. N2 backup to multiple units (electrical or PORV's is credited and is not a cross connected mechanical cross-unit ties).

Use of Symptom based Yes*
Although decision required, event recognition is not Procedures.
req uired.
FNP Fire Protection Initiatives D Initiatives
- Elimination of Kaowool fire wrap by cable reroute to ensure proper cable separation was complete in 2006
- Fire PRA Model under development
- Safe Shutdown Analysis Revalidation
- OMA Feasibility Study & Compensatory Actions
FNP Fire Protection Summary o OMA along with procedures is the main reason for yes screen criteria o Conservative LOSP assumption has added OMAs o Application of NFPA 805 will significantly reduce OMAs o Thermoplastic cables used in lower voltage applications and low 0/0 o No reliance on cable wrap material proper separation exists for cables.
o FNP believes that 3 of the 8 screening criteria are material.
