CAUSE/CORRECTIVE ACTION/COMMENTS NARRATIVE REPORT At 1105 on April 11, 2004, during low power physics testing an automatic reactor trip occurred due to reactor protection system problems. After replacement of two reactor protection system circuit cards, while re-establishing conditions to continue low power physics testing, another automatic reactor trip occurred at 0347 on April 12, 2004. Additional testing identified a different reactor protection system circuit card failure as the actual cause of both trips. This card was replaced, low power physics testing was completed and the unit continued with startup (LER pending). At 1843 on April 15, 2004 the U2RFI6 outage was completed and the unit was synchronized to the grid. This refueling outage completion date includes an extension of approximately six days primarily due to additional work scope associated with Service Water piping repair. At 1808 on April 16, 2004, with the unit at approximately 31 % power, the main turbine was manually tripped due to turbine control problems. The reactor remained critical. Repairs were completed, the unit was connected to the grid at 1856 on April 17, 2004 and returned to 100% power at 0417 on April 20, 2004.
