1.0 INTRODUCTION

The Virgil C. Summer Nuclear Station utilizes a pressurized water reactor rated at 2775 MWt. The turbine generator is capable of producing approximately 900 MWe net (approximately 936 MWe gross) of electrical power.- The plant is located approximately 26 miles

-northwest of Columbia, South Carolina.

2.0 HIGHLIGHTS For the reporting period of January 1 through December 31, 1986 the plant operated at an average capacity factor of 92.4% and a unit availability of 95.3%. The reactor was critical for a total of 8453.2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months , the generator remained on-line for a total of 8350.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months , and ;

the total gross electrical energy generated for 1986 was 7,478,800 MWh.

This data demonstrates a positive increase in plant performance from the 1985 report.

3.0 SCHEDULED OR FORCED POWER REDUCTION SUMUtIES

- During the 1986 report period the plarit experienced three scheduled and two forced power reductions of greater than 20% which exceeded four hours in duration. The plant experienced six reactor trips and one safety injection.

A. February 2, 1986, 2005 hours0.0232 days 0.557 hours 0.00332 weeks 7.629025e-4 months - REACTOR TRIP FROM 100% POWER CAUSE - Feedwater Pump Trip DISCUSSION - Maintenance submitted a work package and requested a tag out on the condensate polisher panel. A review of the electrical feeder list and the associated drawings was done; however, both the list and drawings were incorrect. When the panel l was deenergized for the tag out, it caused a condenser polisher by-j pass valve to fail close. This isolated the flow of condensate to the deaerator tank. On low deaerator level the feedwater pumps tripped, which caused a Reactor Trip.

CORRECTIVE ACTION - Corrections to the electrical feeder list and drawing were made.

TIME LOST - See next item.

B. February 3, 1986; 0741 hours0.00858 days 0.206 hours 0.00123 weeks 2.819505e-4 months - REACTOR TRIP / SAFETY' INJECTION FROM' 100% POWER f

CAUSE - Low Steamline Pressure DISCUSSION _- During restart from the previous trip, a Reactor Trip

/ Safety Injection occurred while rolling the main turbine. At approximately 400 RPM, the turbine control system expertenced a malfunction which caused a rapid increase in turbine speed. This sudden increase in speed caused a steam flow increase of approximately 50% of full steam flow and a rapid loss of header pressure. Although the header pressure never reached the low setpoint, the rate of pressure decrease was sufficient to actuate the steamline low pressure protection bistables due to rate compensation.

CORRECTIVE ACTT,0_M - During neither the troubleshooting activities nor the subsequent restart were any problems found with the turbine control system. However, a program of increased system monitoring during subsequent plant start-ups was placed ir,to effect.

TIME LOST - Generator was off line 33 hours3.819444e-4 days 0.00917 hours 5.456349e-5 weeks 1.25565e-5 months and 5 minutes.

CORRECTIVE ACTION - The Alterex brushes were replaced and an additional brush was added to increase time between changes. In addition, weekly preventive maintenance and a daily inspection of the brushes were added to normal scheduled maintenance.

May 31, 1986, 1026 hours0.0119 days 0.285 hours 0.0017 weeks 3.90393e-4 months - REACTOR TRIP FROM 100% POWER CAUSE - OTAT Trip Sigi.al.

DISCUSSION - Maintenance personnel were performing a monthly operational test on one of the four nuclear instrumentation power range channels. A second channel was_ inadvertently placed into test, which resulted in an OTAT Reactor Trip. Safety system responses were normal; however, water hammer during the transient caused some condenser damage.

CORRECTIVE ACTION - Five corrective actions resulted from this trip: ,

1. The involved maintenance personnel were counseled on the need for attention to detail.

2. The maintenance personnel responsible for the trip presented

" Lessons Learned" training to the applicable groups.

3. The nuclear instrumentation drawers will be re-labeled during 1987 to make them more easily identified.

4. The nuclear instrumentation procedures were reviewed from a Human Factors standpoint.

5. The condenser was repaired.

E. June 29, 1966, 0215-hours - REACTOR TRIP FROM 90% POWER CAUSE - Low Feedwater Flow DISCUSSION - Reactor Power.had been reduced to 90% for turbine valve testing. The trip was the result of a feedwater isolation valve failing closed. The cause was determined to be oxidation on one of the electrical connectors which powered a solenoid on the valve actuator.

CORRECTIVE ACTION - Three specific actions resulted from this trip:

1. The faulty equipment was replaced.

2. Preventive maintenance inspection of these and similar connectors has been scheduled on a refueling basis.

3. A verification of correct field installation of the connectors was made.

July 27, 1986, 0144 hours0.00167 days 0.04 hours 2.380952e-4 weeks 5.4792e-5 months - REACTOR TRIP FROM 90% POWER E CAUSE - Turbine Trip l

l DISCUSSION - Testing was in progress on turbine control valve #4 l when the reactor tripped. Testing of the #4 valve accounted for i one of the three EHC oil pressure switches being in a tripped state. It was believed that one of the other two switches operated

! spuriously due to vibration induced from the f4 valve going closed.

l This would have accounted for the 2 of 3 logic needed for the trip.

NOTE: See issue H. for September 19, 1986.

CORRECTIVE ACTION - Relocation of the control valve pressure switches has been considered for long term corrective action. In i the interim reactor power was reduced below the Reactor l Trip / Turbine Trip Setpoint (50% Reactor Power) for turbine control valve testing. This power reduction would allow the reactor to remain critical should a turbine trip occur.

DISCUSSION - Reactor power was reduced to 46% for control valve testing. Upon completion of testing, reactor power was returned to 100%.

CORRECTIVE ACTION - None TIME LOST - N/A H. September 19, 1986, 1850 hours0.0214 days 0.514 hours 0.00306 weeks 7.03925e-4 months - POWER REDUCTION TO 46% POWER CAUSE - Turbine control valve testing.

DISCUSSION - Power was decreased for control valve testing. During the test, difficulties were again experienced with an EHC oil pressure switch. Reactor power was held at 46% until repairs on the faulty switch were completed.

CORRECTIVE ACTION - The faulty pressure switch was replaced. It is believed that this pressure switch was the cause of the July 27th trip.

TIME LOST - N/A I. October 7, 1986, 0710 hours0.00822 days 0.197 hours 0.00117 weeks 2.70155e-4 months - FORCED OUTAGE TO 0% POWER CAUSE - The inability to verify that the amount of Reactor Coolant System (RCS) " unidentified" leakage was less than one GPM.

DISCUSSION - On October 7, 1986, at 0410 the licensee entered the 4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months Technical Specification action statement for excess

" unidentified" RCS leakage. At 0530 a controlled shutdown at a rate of 1% per minute was initiated. By 0710 the main generator j had been removed from the grid and at 0810 a notification of unusual event was declared due to the excessive unidentified leakage. At 0935, the reactor was shutdown and repairs commenced on the RCDT relief valve which had failed to seat properly. At

! 1018 the unusual event was terminated after repair teams had '

temporarily repaired the RCDT relief valve, and subsequent accurate leak rate determinations could be accomplished.

PAGE 5 0F 7

After final repairs were made the plant commenced start-up and at 1010 on October 9 achieved criticality. The generator was tied to the grid at 1520 the same day.

CORRECTIVE ACTION - Maintenance replaced the reactor coolant drain tank relief valve.

DISCUSSION - On November 7, 1986, at 1100, reactor power was reduced due to a feedwater valve packing leak and at 0730 on November 8 the main generator was removed from the grid. Reactor power.was maintained at 2% so that repairs could be carried out.

Upon completion of repairs, power escalation commenced at 0943 on l November 9. Later that day at 1041, the main generator was tied to l

the grid.

l CORRECTIVE ACTION - Maintenance repacked the valve and replaced a faulty feedwater pump speed controller.

DISCUSSION - On December 4, 1986, at 1100, a controlled shutdown was initiated due to problems with a reactor coolant _ drain tank pump. The main generator was removed from the grid at 1325 and the reactor shutdown at 1345 the same day. Upon correction of the problem,:the plant returned to the grid on December'6 at 0100.
