Cook Unit 2 D. L. Bublick (616) 465-5901 Jan 5, 1995 Page 1 of 2 MONTHLY OPERATING ACTIVITIES DECEMBER 1994 HIGHLIGHTS The unit entered this reporting period in Mode 3.

The Unit was shutdown in support of the cycle 9 to 10 maintenance/refueling outage.

The reactor was taken critical on December 10, 1994 at 0804 for the first time in cycle 10.

The first entry into Mode 1 was made on December 11, 1994 at 1049.

The main turbine generator was paralleled to the grid on December 11, 1994 at 1514.

During the subsequent power increase a reactor trip at 194 RTP occurred which was generated from an MSR high level trip signal.

The cause of the trip signal could not be conclusively determined.

The reactor was taken critical on December 12, 1994 at 2033.

Mode 1 was entered on December 12, 1994 at 2250.

.The main turbine generator was paralleled to the grid on December 13, 1994 at 1949.

Reactor power increase was commenced per the power ascension program.

The unit exited this reporting period in Mode 1 at 100%

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

Gross electrical generation for the month of December was 312580 MWH.
