SUMMARY
OF OPERATING EXPERIENCE DOCKET NO.
50/395 UNIT V. C. SUMMER I DATE February 4, 2003 COMPLETED BY W. H. BELL TELEPHONE (803) 345-4389 January 2003 On 01/09/03 at 02:10 the calorimetric computer program used to calculate the feedwater flow rate based value of reactor thermal power (Fivcals) locked up and began returning exactly the same value of core thermal power.
This condition continued until 04:42 at which time the Plant Computer group corrected the problem. As a result of this problem with the calorimetric, reactor thermal power was reduced to approximately 99% at 03:35. After the calorimetric was restarted power escalation began at 05:35 and 100% power was restored at 06:50 on the 9th.
On 01/17/03 at 14:43 a reactor shutdown began due to the "B" reactor trip breaker being declared inoperable.
However, by 15:10 the breaker was repaired and declared operable and the shutdown was terminated. Power escalation began at 15:55 and was restored to 100% at 16:25.
The plant operated at 100% power at all other times during the month.
