NINE MILE POINT NUCLEAR STATION UNIT #1 k

NARRATIVE OF OPERATING EXPERIENCE i

The station operated during the month of October 1984 with i

a Unit Availability Factor of 100.0%

and a Net Design Electrical Capacity Factor of 97.1%

There were O

challenges to Electromatic Relief Valves. Reductions in Capacity Factor were due to Warm circulating water tempera tures.

CLASS I WORK - MECHANICAL MAINTENANCE - OCTOBER 1984 WR# 29153

1. 13 Rx. Bldg. Closed Loop Cooling Heat Exchanger inspected, checked for leaks, plugged tubes, WR# 28755 Air Start Solenoid on 102 D/G - replaced air start valve WR# 29235 Diesel Generator 102 - repaired fuel oil leak WR# 26237 Snubber #39-HS Tightened cylinder bolts, WRs 28115 50V Bracket for Valve 201.7 installed new tapered washer WRt 29254 Rx. Bldg. Air Lock 261' - greased fittings, tightened up screws, and cleaned dirt from door stop WR# 29731

Circuit check acceptable, and diesel started properly.

WR# 29202 Post Accident Sampling - Solenoid Valve 122-04 was replaced with an equipment qualified solenoid.

WR# 29205 Reactor Building Closed Loop Cooling - #11 (70-01) motor was rewound due to a turn to turn short.

MO 1927 This major order involves updating station equipment for Equipment Qualification. The work performed includes wiring replacement solenoids, position limit switenes, dif ferential pressure transmitters and sealing the condulets.

The systems involved are Emergency Condenser Vent,* Reactor Building Emergency Ventilation, Condensate Make up to Torus, Containment Spray and Containment Spray Cooling Raw Water.
