NARRATIVE

SUMMARY

f MONTH: December,1996 i Catawba Unit I began the month of December operating at 100% full power. On 12/05/96 at 2005 the unit j began reducing power to permit inspection of the lower containment in a effort to identify source of  ;

primary leakage of-0.5 gpm. On 12/06/96 at 0500 the unit was taken off-line due to failed weld on reactor coolant pump "lD" #1 seal leak-off line. The unit was placed on-line 12/09/96 at i104. During power  !

escalation, the unit held at 16% power from 1309 to 1444 to investigate a spurious actuation of steam i generator "lC" power operated relief valve. The unit returned to 100% full power on 12/10/96 at 0910 and operated at or near 100% full power until 12/30/96 at 2129 when the unit began reducing power and l was taken off-line at 2332 due to secondary safety protective system main steam isolation relay failed I

, during surveillance testing. On 12/31/96 at 1440 the unit was placed on-line. The unit returned to l approximately 78% full power by 12/31/96 at 2400.

NARRATIVE

SUMMARY

MONTH: December,1996  :

Catawba Unit 2 began the month of December operating at 100% full power. "Ihe unit operated at or near 100% full power until 12/14/96 at 1350, when the unit began decreasing power and was taken off-line at {

2347 due to residual heat removal pump operability concems due to leakage on unseated check valves. The unit was placed on-line 12/22/96 at 0608. During power escalation, the unit held at 15% power from 0630 i to 1205 pending main feedwater nozzle swap. The unit held at 52% power from 1530 to 1622 due to main turbine stop valve movement test. The unit returned to 100% full power on 12/23/% at 0720, and operated at or near 100% full power the remainder of the month.
