Docket No.: 50-31 5 Unit Name: D.'. Cook Unit 1 Date: March 13 1978 Completed By: R. S. Keith Telephone: 616 465-5901 OPERATING EXPERIENCE - FEBRUARY, 1978 Hi hli hts Unit 1 operated in the Deicing Mode the entire month with inlet temperatures averaging 34.5 F.

Reserve power was lost for a period of 7.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months when an insulator flashed over and tripped breakers 12AB and 12CD.

~Summa r 2/1/78 - At the beginning of the month Unit 1 was at 100Ã power.

2/2/78 - Power was reduced to 501 and steam from Unit 1 was used to roll Unit 2 Turbine-Generitor up to rated speed.

2/5/78 - Testing of Unit 2 Turbine-Generator was completed and Unit 1 was retunned to 100Ã power.

2/11/78- At 0059 hours6.828704e-4 days 0.0164 hours 9.755291e-5 weeks 2.24495e-5 months Unit 1 tripped while conducting a routine test of the Solenoid Trip Valve.. Subsequent testing using a revised procedure eliminated the cause of the trip.

2/12/78- The Reactor was critical at 0035 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months and the unit was paralleled to the grid at 0159 hours0.00184 days 0.0442 hours 2.628968e-4 weeks 6.04995e-5 months .

2/14/78- Unit 1 lost the preferred off-site reserve power. The loss of power was caused by an insulator flashing over on the 34.5 KV transformer. The insulator was cleaned and the preferred reserve power sources were restored to normal standby operation.

2/18/78- Power was reduced to 65K to perform Excore/Incore Detector calibration.

2/19/78- Power return .to.'100/ was started at 1800 hours.,

Routine power operation at 100K continued throughout the remainder of the month.

1. Name of facility.

2. Scheduled date for next refueling shutdown.

3. Scheduled date for restart following refueling.

4. Mill refueling or resumption of operation thereafter require a technical specification change or other license amendment?

If answer is yes, what, in general, will these be?

If answer is no, has tne reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50 '9)?

If no such review has taken place, when is it scheduled?

5. Scheduled date(s) for submitting proposed licensing action and supporting information.

6. Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures.

7. The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool.

8. The present licensed spent fuel pool storage capacity and the size of any '.ncrease in licensed storage capacity that has been requested or is planned, in number of'uel assemblies.

9. The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity.
