The team identified an
URI related to licensee reliance on many local
manual operator actions for mitigation of Appendix R,
Section III.G.2 fires, where operators would be shuting down the plant from the main control room. This issue is unresolved pending further NRC review of the licensing basis. The team noted that the licensees procedure
AOP-N.08, Appendix R Fire SSD, relied on many local
manual operator actions to mitigate a fire in FAA-070 or FAA- 095 in lieu of protecting or separating cables per Appendix R,
Section III.G.2. The licensee had no approved NRC deviations from the requirements of Appendix R,
Section III.G.2 for these manual actions. However, licensee personnel believed that some of the actions had been specifically reviewed and accepted by the NRC, as documented in Inspection Report 05000327,328/88-24, which was referenced by NRC
SER (
NUREG-1232). The licensee also stated that the NRC had approved a general reliance on local
manual operator actions instead of protecting or separating cables per Appendix R,
Section III.G.2. The licensee had reviewed and walked down each action, and considered each action to be feasible. With the exception of the action to locally control motor driven
AFW pump flow (described above), the team found these actions to be feasible. This issued is unresolved pending further NRC review of the licensing basis. This issue is identified as
URI 05000327,328/2005011-05, Reliance on Local
Manual Operator Actions for Appendix R Fires.
