SUMMARY
NOVEMBER 1989 UNIT 1 Unit I continued to operate efficiently during November. It generated 849,360 MWh (gross) of electrical power with a capacity factor of 99.72 percent. Unit 1 operated at approximately 100 percent power throughout the month.
UNIT 2 Unit 2 generated.490,760 MHh (gross.\ of electrical power during November with a capacity factor of 57.62 percent.- To extend the life of the core, the unit operated at 75 percent power until November 8,1989, when it was taken offline _
for work on the reactor head-vent valves. Unit 2 tied online again on November 15, 1989, at 2047 (EST), and was brought to 85 percent power on November l', 1989. The power level was held at 85 percent to extend the life of the core.
Unit.2 power level was increased to 100 percent on November 29, 1989, to help meet load demands on the grid. The unit was operating at approximately 100 percent at the end of November.
POWER-OPERATED RELIEF VALVES (PORVs) AND SAFETY VALVES
SUMMARY
There were no challenges to PORVs or safety valves in the month of November.
OFFSITE DOSE CALCULATION MANUAL (ODCM) CHANGES There were no changes to the ODCM in the month of November.
