NIAGARA MOHAWK POWER CORPORATION NINE MILE POINT NUCLEAR STATION UNIT #1 NARRATIVE OF OPERATING EXPERIENCE NOVEMBER 1980 The station operated with a monthly availability factor of 100% and a net design electrical capacity factor of 89.9%.

During the entire month #15 Reactor Recirculation Pump was out of service and isolated due to mech-anical problems.

Capacity factor loss was due to the following:

From November 1 through November 18 the unit operated at approximately 95% thermal power (end of cycle thermal power derate). On November 18 the reactor entered into the third cycle coastdown, to 93.5% thermal power limit.
