COOPER NUCLEAR STATION OPERATIONS NARRATIVE November 1979 Power was reduced on November 11, 1979 to allow the exchange of control rod patterns (Sequence A-2 to Sequence B-2) and to test the turbine control system.

On November 13, 1979, diesel generator #1 would not start during per-formance of a surveillance procedure and was declared inoperable.

Diesel generator #2 was undergoing its annual inspection and thus was also inoperable. Power was reduced for a normal station shutdown as required by Technical Specifications. Diesel generator #1 was sub-sequently repaired, tested, and declared operable and the shutdown terminated. The reactor returned to reduced power operation pending completion of repair and annual inspection of the #2 diesel generator.

Reactor was shutdown on November 14, 1979 because the repair and annual inspection of the #2 diesel generator was not completed in seven days as required by Technical Specifications. The diesel generator #2 was repaired, tested, and declared operable and the reactor returned to normal operation after a 148.8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> outage.

Reactor operated with no additional unscheduled power reductions or outages for the balance of the month.
