DOCKET NO.: 50-3 16 UNIT NAME: D.C. Cook Unit 2 COMPLETED BY: D. L. Bublick TELEPHONE: (616) 465-5901 DATE: Sept 6, 1994 PAGE0 Page 1 of 1 MONTHLY OPERATING ACTIVITIES AUGUST 1994 HIGHLIGHTS The unit entered this reporting period in Mode 1 at 724 RTP.

End of core life power coastdown program continues in preparation for the cycle 9 to 10 refueling outage.

On August 15, 1994 at 2351, a turbine trip followed by a reactor trip occurred due to blockage of feedpump condenser tubes.

The reactor was taken critical on August 16, 1994 at 2222. Mode 1 was entered on August 17, 1994 at 0105 followed by the parallel to the grid at 0430 the same day. Power increase was commenced per the power ascension program.

The unit exited this reporting period in Mode 1 at 484'TP.

There were no challenges to the pressurizer safety valves or power operated relief valves.

Gross Electrical generation for the month of August was 402090 MWH.

DETAILS 8-15-94 2351 Reactor trip/turbine trip. Blockage of feedpump condenser tubes caused low feed pump condenser vacuum, resulting in a turbine trip. This turbine trip caused a reactor trip. RCS in Mode 3.
