NIAGARAMOHAWKPOWER CORPORATION NINE MILEPOINT NUCLEAR STATION UNIT ¹1 NARRATIVEOF OPERATING EXPERIENCE The Station operated during the month of March 1991 with a Unit AvailabilityFactor of 27.5%

and a Net Design Electrical Capacity Factor of 21.7%.

There were no challenges to Electromatic Relief Valves.

Reductions in Capacity Factor were due mainly to a scheduled midcycle outage for surveillance testing.

Other reductions in capacity factor were due to weekly control rod exercising and the inability to obtain 100% CTP due to turbine steam flow limitation. Upon completion of the outage, the unit was synchronized to the grid on 3-23-91 at 1106.
