NIAGARA M0 HAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT #1 NARRATIVE OF OPERATING EXPERIENCE The Station operated during the month of July 1987 with a Unit Availa-bility Factor of 100.0% and a Net Design Electrical Capacity Factor of 79.8%.

There were no challenges to Electromatic Relief Valves.

Reductions in Capacity Factor were due to Control Rod Sequence Exchange, high lake temperature, and limited to 90% CTP by three (3) recirculation pump opera-tion.
