TELEPHONE 612-388-1121-4376 MONTH: DECEMBER 1993 For'the first part of December, Unit 2 continued with cycle 16 refueling and maintenance outage. The end_of the outage began-when the Unit started to leave cold shutdown at 1349 of the 10th.

The reactcr went critical at 1021 of the 15th and the generator was' connected to the grid at 1728 of the 16th.

During the ramp'up, on Dec 19, control valve (CV-2) oscillated a few times causing the operators'to place the turbine control in manual and reducing power to allow repair to CV-2. The problem was identified and corrected on the 20th and the Unit returned-to ramp up to full power. On the 21st at 2130 the Unit' reached full power operation.

The outage, from breaker to breaker, was 48 days, 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> and 11 minutes.
