SUMMARY

OF OPERATING EXPERIENCE DOCKET NO. 50/395 UNIT V. C. SUMMER I DATE 03/01/2002 COMPLETED BY W. H. BELL TELEPHONE (803) 345-4389 FEBRUARY 2002 On 02/02/02 at 02:26 a reduction to 98% power was initiated to support repairs to ILT03763A, 1A feedwater heater level transmitter. 98% power was achieved and maintained until repairs were completed at 20:28 at which time power escalation began. 100% power was restored at 23:55.

On 02/18/02 at 20:55 a turbine load reduction was initiated to support a reduction to 98% power due to low air pressure on MSIVs A and C. At 21:02 C MSIV pressure returned to the normal range and the load reduction was terminated. At 21:29 A MSIV pressure also returned to normal. On 02/19/02 at 02:20 a return to full power began. At 02:45 power was stabilized at 100%. V. C. Summer Station operated at 100% power at all other times during the month.
