NINE MILE POINT NUCLEAR STATION UNIT #1 l NARRATIVE OF OPERATING EXPERIENCE l

The station operated during the month of April 1987 with a Unit Availability )

Factor of 100.0% and a Net Design Electrical Capacity Factor of 97.87.. There '

were no challenges to Electromatic Relief Valves. Reductions in Capacity Factor were due to weekly Control Rod Exercising and CRD Module maintenance. Also, adjustments were made to the Control Rod pattern including a Sequence Exchange. l l
