NIAGARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT gl NARRATIVE OF OPERATING EXPERIENCE MARCH 978 The station operated at 100Ã availability and 95.5! capacity factor for the month.
The daily operating history follows:
March 1 to March 23 March 23 March 24 March 25 8 March 26 March 27 March 28 March 29 to March 31 March 31 Operated at a steady state power level of approximately 621 MWe and 1836 MWt.
At 2055, started load reduction for a control rod sequence change.
At 2220, the unit load was 290 MWe with recirculation flow at minimum.
At 0320 after the control rod sequence change was completed, unit load was 161 HWt.
Started to pull rods to increase load.
At 2230, unit load was 352 MWe.
Continued to increase load at the preconditioning rate via recirculation flow increases.
Continued to increase load within PCIOMR Limits.
Load at 582 MWe and 1750 HWt.
Continued to increase load at preconditiong rate.
At 0000, unit load was 601 HWe and 1807 MWt.
Continued to increase load at the pre-con-ditioning rate.
At 0800, unit load reached 616 MWe and 1815 HWt.
Holding here due to core thermal limits.
Steady state operation of approximately 602 HWe and 1785 HWt.
At 2200, started a load reduction via recirculation flow for economy reasons.
At 2300, unit load reached 325 MWe and 1042 MWt.
