SUMMARY
South Texas Project Unit 2 began the reporting period shutdown for scheduled refueling and steam generator replacement. The unit was returned to service on December 6, at 0509 and full power was achieved on December 13, at 1114.
On December 15, at 1805 the reactor was manually tripped due to a sudden high main turbine vibration. After opening the turbine and condenser, one last row blade on low-pressure (LP) rotor 22 had separated from the rotor causing some collateral damage within LP 22. Numerous last row blade cracks were discovered during visual inspections of the blades on LP 22 and 23.
Additional damage was found on stationary blades in 22, the exhaust flow guide and some condenser tubes. Metallurgical examinations found the cracks as a result of high cycle fatigue.
The unit remained shutdown at the end of the reporting period with repairs ongoing.
