2Q/08: Changed PRA Parameter(s). A new PRA model (2006C) was approved and implemented in the 1st Quarter of 2008. PRA coefficients were updated in CDE to reflect the new model, effective for the 2nd Quarter of 2008.

3Q/07: During the 3rd quarter 2007, an error was discovered in the PRA model of record (2006B). Because the error was non-conservative, it was decided to rescind 2006B and re-instate the last PRA model that did not contain the error (2003A). Because this was at variance with NEI 99-02 guidance, FAQ #74.0 was submitted to review this decision. The FAQ was reviewed by the ROP task force and it was determined that the correct course was to use the 2006B model regardless of the error for the 3rd quarter 2007 PI submittal. The data submittal reflects the 2006B PRA model. This issue has been entered into the corrective action program. No MSPI thresholds were crossed using either model, and all indicators remain Green.

2Q/07: A new PRA model (2006A) was approved and implemented in the 1st quarter 2007. PRA coefficients were updated to reflect the new model in the 2nd quarter 2007, in accordance with FAQ 419. During this update, the values for Core Damage Frequency (CDF) were inadvertantly not revised. This was discovered during the 3rd quarter 2007, and the 2nd quarter 2007 CDF values were corrected. There was no change in color for any MSPI indicator. This issue has been entered into the corrective action program. Also during the 3rd quarter 2007, a configuration discrepancy was identified in CDE regarding the Unit 0 diesel generator and associated cooling water pump. Component reliability was inadvertantly not included in the Unit 2 unreliability index calculations for Emergency AC and Cooling Water System MSPI. This discrepancy had existed since MSPI implementation. The components have been properly configured back to the 2nd quarter 2006, and the issue was entered into the corrective action program. No MSPI thresholds were crossed, and all indicators remain Green.

1Q/07: During the 3rd quarter 2007, a configuration discrepancy was identified in CDE regarding the Unit 0 diesel generator and associated cooling water pump. Component reliability was inadvertantly not included in the Unit 2 unreliability index calculations for Emergency AC and Cooling Water System MSPI. This discrepancy had existed since MSPI implementation. The components have been properly configured back to the 2nd quarter 2006, and the issue was entered into the corrective action program. No MSPI thresholds were crossed, and all indicators remain Green.

4Q/06: An internal review identified a number of minor discrepancies in MSPI data submitted in previous quarters. These discrepancies have been corrected in the 4th quarter 2006 submittal, and did not result in a change in current or past indicator color. This occurrence has been entered into the plant's corrective action program. During the 3rd quarter 2007, a configuration discrepancy was identified in CDE regarding the Unit 0 diesel generator and associated cooling water pump. Component reliability was inadvertantly not included in the Unit 2 unreliability index calculations for Emergency AC and Cooling Water System MSPI. This discrepancy had existed since MSPI implementation. The components have been properly configured back to the 2nd quarter 2006, and the issue was entered into the corrective action program. No MSPI thresholds were crossed, and all indicators remain Green.

3Q/06: During the 3rd quarter 2007, a configuration discrepancy was identified in CDE regarding the Unit 0 diesel generator and associated cooling water pump. Component reliability was inadvertantly not included in the Unit 2 unreliability index calculations for Emergency AC and Cooling Water System MSPI. This discrepancy had existed since MSPI implementation. The components have been properly configured back to the 2nd quarter 2006, and the issue was entered into the corrective action program. No MSPI thresholds were crossed, and all indicators remain Green.

2Q/06: During the 3rd quarter 2007, a configuration discrepancy was identified in CDE regarding the Unit 0 diesel generator and associated cooling water pump. Component reliability was inadvertantly not included in the Unit 2 unreliability index calculations for Emergency AC and Cooling Water System MSPI. This discrepancy had existed since MSPI implementation. The components have been properly configured back to the 2nd quarter 2006, and the issue was entered into the corrective action program. No MSPI thresholds were crossed, and all indicators remain Green. An internal review identified a minor discrepancy in MSPI data submitted for April 2006. This discrepancy was corrected in the 2nd Quarter 2008 submittal, and did not result in a change in current or past indicator color. This occurrence has been entered into the plant's corrective action program.

3Q/07: An internal audit identified that an opportunity had been counted in the August 2007 data that had not been properly evaluated. This decreased the number of total drill, exercise and event opportunities from 53 to 52. This error had no impact on the Performance Indicator color, and has been entered into the plant's corrective action program. A subsequent internal audit identified that an opportunity had been counted in the August 2007 data that should have been counted in the June 2007 data. This decreased the number of total drill, exercise and event opportunities in August 2007 from 52 to 36. This error had no impact on the Performance Indicator color, and has been entered into the plant's corrective action program.

2Q/07: An internal audit identified that an opportunity had been counted in the August 2007 data that should have been counted in the June 2007 data. This increased the number of total drill, exercise and event opportunities in June 2007 from 12 to 28. This error had no impact on the Performance Indicator color, and has been entered into the plant's corrective action program.

4Q/06: An internal audit identified that an opportunity had been counted in the October 2006 data that should have been counted in the September 2006 data. This decreased the number of total drill, exercise and event opportunities in October 2006 from 25 to 18. This error had no impact on the Performance Indicator color, and has been entered into the plant's corrective action program.

3Q/06: An internal audit identified that an opportunity had been counted in the October 2006 data that should have been counted in the September 2006 data. This increased the number of total drill, exercise and event opportunities in September 2006 from 0 to 7. This error had no impact on the Performance Indicator color, and has been entered into the plant's corrective action program.
