SUMMARY
OF OPERATING EXPERIENCE DOCKET NO.
50/395 UNIT V. C. SUMMER I DATE July 2,2002 COMPLETED BY W. H. BELL TELEPHONE (803) 345-4389 Jun-02 At the beginning of the month V. C. Summer Station was in Mode 2 while beginning the initial startup after the 13th refueling outage. The reactor became critical at 02:46 on 06/01/2002. The reactor automatically tripped due to a spike in intermediate range nuclear instrumentation channel NI 36. After replacing a circuit card in NI 36 the reactor was restarted and became critical at 18:57 on 06/02/2002. The main generator breaker was closed at 13:11 on 06/03/2002.
At 03:39 on 06/08/2002 the main generator breaker was opened to permit the performance of a main turbine overspeed test. The test was successfully completed and the breaker was closed at 09:24 on 06/08/2002. The reactor remained critical throughout this test evolution.
At 19:02 on 06/17/2002 the reactor tripped on lo lo level in the A steam generator. The low level was caused by the trip of the C main feedwater pump in conjunction with a feedwater digital control system logic error that inadvertently caused the feed pump recirculation valves to go full open. After the feed pump was repaired and the control logic corrected the reactor was restarted and became critical at 23:38 on 06/18/2002. The main generator breaker was closed at 11:16 on 06/19/2002. The plant remained on line for the remainder of the month.
