NINE MILE POINT NUCLEAR STATION UNIT f1 NARRATIVE OF OPERATING EXPERIENCE The station operated during the month of October 1986 with a Unit Availability Factor of 100.0% and a Net Design Electrical Capacity Factor of 96.6%.
There were no challenges to Electromatic Relief Valves. Reductions in Capacity Factor were due to power reductions for weekly control rod exercising and minor control rod pattern adjust-ments for thermal limit constraints.
