DOCKET NO: 50-316 UNIT NAME: D.C. Cook Unit 2 COMPLETED BY: A. S. Puplis TELEPHONE: (616) 465-5901 DATE: December 2, 1987 PAGE: lof 2 MONTHLY OPERATING ACTIVITIES - NOVEMBER 1987 HIGHLIGHTS The reporting period began with the unit at 80% rated thermal power. The unit remained at 80% power until 12-22-87, when a power reduction to 8% was initiated to add oil to the No. 21 reactor coolant pump motor.

While the unit was at the reduced power level, both main feed pump condensers were cleaned.

A reactor power increase to 80% was initiated on 12-23-87. Reactor power was restored to 80% at 0513 on 12-24-87.

The reporting period ended with the unit at 80% power.

Gross electrical generation was 651,390 MWH for the month.

SUMMARY

12-4-87 Unit 2 CD Emergency Diesel Generator was inoperable from 1058 to 1147 due to a false electronic overspeed .trip signal induced while installing temporary instrumentation for data collection.

12-6-87 At 0025 the West Essential Service Water (ESW) pump discharge valve (2-WM0-704), was declared inoperable due to the valve not fully stroking during its surveillance test. The west ESW header was removed from service at 0401 the same day to troubleshoot 2-WMO-704. The valve was replaced, satisfactorily stroked, and declared operable at 1207 on 12-7-87.

During inspection of the west ESW pump discharge valve, internal corrosion was noticed on the pump discharge check valve (2-ESW-102W). The valve was declared inoperable at 0950 on 12-7-87.

II a

The valve was evaluated and it's condition was determined to be acceptable, following verification of flow and seating capabilities. The valve was returned to service, pending future repairs. Parts are being expedited.

12-22-87 A power reduction to 8$ was initiated at 1800 hours0.0208 days <br />0.5 hours <br />0.00298 weeks <br />6.849e-4 months <br />, to allow oil addition to the 821 Reactor Coolant Pump Notor.

12-23-87 Reactor Power was stabilized at 8% at 1007 hours0.0117 days <br />0.28 hours <br />0.00167 weeks <br />3.831635e-4 months <br />.

At 1105, a power increase was initiated.

12-24-87 Reactor Power was restored to 805 at 0513.

12-31-87 At 0134 Unit 2 entered then exited Technical Specification 3.0.3 to stroke ICN-265, the South Safety Injection Pump Discharge Valve for surveillance testing.
