SUMMARY

OF OPERATING EXPERIENCE DOCKET NO: 50-244 UNIT: R.E. Qinna Nuclear Power Plant DATE: Au ust 13 1996 COMPLETED BY: v v2d John Walden TELEPHONE: 716 771-3588 MONTH Jul 1996 The unit began the month at full power. On July 3, 1996, a pressurizer safety valve began to leak. The unit was manually shut down and placed in mode 5. The reactor coolant system was drained= and safety valve replaced with a spare. While in mode 4, reactor coolant system pressure reached the activation setpoint of the low temperature overpressure protection system. Pressurizer power operated relief valves 430 and 431C opened momentarily and reduced reactor coolant system pressure. The remainder of the start up activities proceeded normally. The unit was placed on-line on July 8, 1996. Full power operations continued from July 9, 1996 to July 23, 1996. A power reduction occurred on July 23, 1996 due to a leaking containment spray test line. The power reduction was halted when the condition was cleared. The unit was brought back to full power on July 24, 1996 and remained there for the rest of the month.
