i NIAGARA h!0llAWK POWER CORPORATION NINE blILE POINT NUCLEAR STATION UNIT #1 NARRATIVE OF OPERATING EXPERIENCE The station operated during the month of October 1985 with a Unit Availability Factor of 100.0 and a Net Design Electrical Capacity Factor of 94.7.

There were O challenges to Electromatic Relief Valves. Reductions in Capacity Factor were due to load reductions to pull control rods and preconditioning of fuel.
