SUMMARY
OF OPERATING EXPERIENCE DOCKET N0% 50-389 UNIT St. Lucie 2 DATE COMPLETED BY J.J. Breen TELEPHONE 407 468-4248 REPORT MONTH MAY 1993 From May 1, 1993, until May 16, 1993, Unit 2 was at 100~ power. On May 17, 1993, Unit 2 was downpowered to approximately 754 power to investigate a potential condenser tube leak. On May 21, 1993, Unit 2 was being held at approximately 724 power when the Unit was manually tripped due to the dropping of several Control Element Assemblies (CEA's). It was determined that the dropping of the CEA's were caused by an electrical grounding problem; this event will be reported by Licensee Event Report (LER) 93-07. On May 26, 1993, the CEA electrical grounding problem was corrected, the potential condenser tube leak disappeared and the Unit was placed online. The Unit was held at approximately 204 power to repair a DEH leak on governor valve g2 of the turbine. Repairwork was completed on May 26, 1993, and Unit 2 was increased in power. From May 27, 1993, until May 28, 1993, Unit 2 was held at approximately 804 to 854 power for waterbox cleaning. On May 29, 1993, Unit 2 was at 100% power and remained there for the rest of the month.
In accordance with the requirements of Technical Specification 6.9.1.6, there were no challenges to the PORVs or safety valves during the report period.
