PLANT PERFORMANCE

SUMMARY

PR CISIONAL CALLAWAY PLANk Assessment Period: January 2002 through June 2002 (includes data from July 2001 through June 2002)

I Operating Summarv The plant operated at essentially 100 percent power until December 3, 2001, when the unit was shut down to repair a stator cooling water leak into the main generator. The unit was restarted on December 6 and reached full power on December 8. The unit remained at full power until January 31, 2002, when it was shutdown to inspect the CST cover. The unit was restarted on February 15. On May 6, power was reduced to approximately 70% to perform work on a main feedwater pump. The plant returned to 100 percent on May 7 and operated at essentially full power for the remainder of the period.

II Performance Overview A. Current Overall Assessment Overall plant performance is in the Regulatory Response Column of the Action Matrix, as a result of a White finding in the Mitigating Systems cornerstone in February 2002.

B. Previous Assessment Results In the first quarter of 2002, plant performance was in the Degraded Cornerstone column as a result of two White findings in the Mitigating System comerstone (ESW pump in June 2001 and the AFW issue in February 2002). Prior to that, the licensee was in the Regulatory Response Column as a result of the inoperable ESW pump issue identified the 2nd quarter of 2001.

Inspection Findinqs: No findings were identified during the most recent quarter, and no findings were identified during the previous two quarters.

Performance Indicators: All three performance indicators were green throughout the inspection cycle.

Mitigating Systems Inspection Findinqs: Over the course of the assessment period (the last six months), the inspectors identified a number of green findings that were examples of problem identification and resolution issues. Specifically, (1) a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to take adequate corrective actions to repair, and prevent recurrence, of a deficiency associated with an EDG overspeed trip switch (July 6, 2002), (2) a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to address a flow anomaly condition in AFW Train B that had existed between February 2000 and March 2001 (March 13, 2002), (3) a White issue was identified regarding the licensee's failure to identify and correct a significant condition adverse to quality involving foreign material in the CST. Additionally, a finding was identified regarding the licensee's poor performance associated with missed opportunities to identify and correct the degraded CST cover (February 27, 2002), and (4) a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to take corrective action to correct abnormally high vibration on both motor-driven AFW pumps (February 8, 2002).

During the past 12 months, In addition to the above-listed items, the following corrective action issues were identified: (1) A noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when a previously identified condition, associated with auxiliary feedwater minimum discharge pressure and recirculation flow, had not been corrected (November 26, 2001); and (2) a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to take corrective action to ensure flood doors leading Into the emergency core cooling system pump rooms were properly controlled (October 7, 2001).

IV. Other Issues A. Inspection Results for Cross-Cutting Areas "Human Performance: No significant issues or findings.

"Safety-Conscious Working Environment: No issues or findings.

"Problem Identification and Resolution: Over the course of the assessment period, the inspectors identified six Green findings and one White finding that were examples of poor implementation of corrective actions.

A noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to take adequate corrective actions to repair, and prevent recurrence, of a deficiency associated with an EDG overspeed trip switch (July 6, 2002).

A noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to address a flow anomaly condition in AFW Train B that had existed between February 2000 and March 2001 (March 13, 2002).

A White Issue was identified regarding the licensee's failure to identify and correct a significant condition adverse to quality involving the degradation of the CST cover and subsequent introduction of foreign material into the CST. Additionally, a finding was identified regarding the licensee's poor performance associated with missed opportunities to identify and correct the degraded CST cover (February 27, 2002).

A noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to take corrective action to correct abnormally high vibration on both motor-driven AFW pumps (February 8, 2002).

A noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when a previously identified condition, associated with auxiliary feedwater minimum CALLAWAY

discharge pressure and recirculation flow, had not been corrected. (November 26,2001)

A noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, occurred when the licensee failed to take corrective action to ensure flood doors leading into the emergency core cooling system pump rooms were properly controlled.

V. Miscellaneous TopicslConcluslons/Recommendations Proposed inspection plan:

A 95002 supplemental inspection pertaining to inoperability of the auxiliary feedwater pump will be performed in August 2002.
