RTP conducting turbine generator vibration testing. The turbine generator was paralleled to the grid on December 2, 1992 at 0527 followed by the removal of the turbine generator from the grid at, 0910 due to high vibrations.

Following generator bearing clearance adjustments and generator hydrogen seal modifications, the turbine generator was paralleled to the grid on December 19, 1992 at 1500 followed by reactor power increase to 100% per the power ascension testing program. The reactor was at 100% RTP on December 26( 1992 at 2054.

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 256060 MWH.

DETAILS 12-2-92 0527 Turbine Generator paralleled to the grid.

12'-2-92 0910 Turbine Generator removed from the grid.
