Docket Mo. 50-277 50-278 Attachment to Monthly Operating Report for Seotember, 1983 Peach Bottom Atomic Power Station Narrative Summary of Operating Experiences Sectember, 1993 Unit 2 Unit 2 remained shutdown for the entire month of September for inspection of primary sfstem oiping welds on the reactor recirculation system and shutdown cooling system.

During the month of September, all the required weld examinations were completed and 20 welds were discovered with confirmed IGSCC indications. 16 of these 20 welds were dispositioned by GE for weld overlay repair. The remaining four welds were analyzed and determined by GE to allow safe operation for 24 months, thus supporting returning the unit to service for the six months remaining in this fuel cycle.

By the end of September, 3 of the 16 welds dispositioned by GE for weld overlay repair were overlaid and re-examined.

Unit 3 The NRC Confirmatory Order and Safety Evaluation granting permission for unit restart was granted on September 1, 1993. Rod withdrawal began September 2 with slightly degraded mechanical vacuum pump performance. During the period of Sentember 3 tc September 6, the mechanical vacuum pump problem was investigated and repaired. Feedwater chemistry revealed a waterbox leak which was reoaired on September 6 On September 6, condenser vacuum was restored and reactor pressure was increased to 1000 psig on September 7 On September 8, high drvwell pumpout rates and an al arm received f rom the moisture monitoring tape system installed on the recirculation system piping initiated an investigation into the source of the leakage. The leakage was found to be a bonnet flange leak in the B recirculation pump discharge valve. Cold shutdown was initiated late on September 8 for repairs to the valve. Repairs to the B recirculation pump discharge valve have been comoleted. On Sentember 11, a generator rotor ground waJ discovered and an investigation began. Unit startup is pending resolution of the generator rotor ground. On September 14, efforts began to pull

Docket No. 50-277 50-278 Attachment to Monthly Operating Reoort for September, 1983 4

the generator rotor to determine the source of the ground. The ground was discovered during inspection on September 24 in the end ring area of the rotor. The creepage blocks, wedges and end turn blocks were removed and sent to the vetidor's shop for cleaning during the period of September 26-30. By September 30, the rotor was reassembled except for the retaining ring due to the unavailability of the necessary insulation.
