Licensee Comments:

3Q/08: Oconee Problem Identification Process (PIP) 08-05623 identified that the MSPI baseline for Emergency AC Power (EAP) was not revised in 2Q2008 to subtract hours included from a previous refurbishment outage. By not removing these refurbishment hours, the EAP MSPI results reported for 2Q2008 and 3Q2008 are non-conservative pending the CDE software changes to allow revisions to current and past quarters. The baseline is corrected for 4Q2008. The Oconee Emergency AC Power Units remain Green with adequate margin to White.
