SUMMARY
OF OPERATING EXPERIENCE UNIT TWO NOVEMBER, 1986 11-01-86 to 11-30-86 Unit 2 entered the month operating at a power level of 650 MWe and operated continuously at maximum core flow (coastdown) until November 29, 1986 at 0916 hours0.0106 days <br />0.254 hours <br />0.00151 weeks <br />3.48538e-4 months <br />, when the turbine was manually tripped off-line to the unit's tenth refueling outage..The reactor was manually scrammed at 1703 of the same day when the mode switch was purposely moved from "run" to
" shutdown" mode.
Capacity factor for the month was 70.26% and avail-ability was 94.62%.
