T NIAGARA N0llAWK POWER CORPORATION NINE b1ILE POINT NUCLEAR STATION UNIT #1 NARRATIVE OF OPERATING EXPERIENCE The station operated during the month of August 1985 with a Unit Availability Factor of 95.0 and a Net Design Electrical Capacity Factor of 84.1.

There was 1 challenge to Electromatic Relief Valves as a result of the Rx Scram 8/19/85. Reductions in Capacity Factor were due to seasonally high circulating water temperatures, control rod pattern adjustments and one automatic reactor shutdown due to equipment failure and one automatic reactor shutdown due to personnel error.
