2Q/08: Evaluation of relay testing results for Breaker 152-209 associated with Auxiliary Feedwater Pump P-8C concluded the equipment remained capable of performing their design functions and were operable. (Reference CR-PLP-2008-01473). This submittal includes revision to previously submitted planned unavailability hours due to missed flow controller testing (RI-95). Data updates made in Jan 06, Feb 06, Sep 06, Dec 06, Jul 07, and Mar 08 with a small impact on MSPI result and no impact on the ???color??? of the indicator. Extent of condition reviews are in progress due to this issue. (Reference CR-PLP-2008-02172).
1Q/08: Evaluation is pending on relay testing results for Breaker 152-209 associated with Auxiliary Feedwater Pump P-8C. (Reference CR-PLP-2008-01473).
4Q/06: 5 failures were reported in November related to switch/controller mis-positionings. These were associated with AFW Pump handswitches (3 failures) and AFW Flow Control Valve controller position (2 failures). The failures were reported in Palisades LER 2006-007, Auxiliary Feedwater Control Switches Not Position for Automatic System Actuation
