,- Joseph M. Farley Nuclear Plant Unit i Narrative Summary of Operations October 1995 The unit was taken ofTline at 0020 on September 16,1995, for the thirteenth refueling outage. ]

1. The following safety related maintenance was performed during the month:

A) Repaired through-wall leak on MOV 8887A.

2. The following maintenance was associated with outage activities:

A) Converted the 1L3 RHR pump from a closed-coupled configuration to a coupled configuration. The change will facilitate the removal and replacement of the motor for repair or replacement without requiring the pump casing to be opened and the pump internals disassembled and will reduce radiation exposure for routine maintenance.

B) Relocated the lower steam generator narrow range level taps to a lower location within the transition cone, allowing for an increased calibrated span on the narrow range level transmitters. The wider span will provide the operators additional time to respond to off normal / transient situations and will minimize the elTects of shrink and swell. As a result of this modification, the reactor trip setpoint, turbine trip setpoint, and AMSAC actuation setpoints have changed, as well as the normal operating band and I

the steam generator level program.

C) Changed the logic of the Reactor Coolant Bus Undervoltage/Underfrequency (UV/UF) relay circuitry associated with reactor protection system (RPS) from " energize to trip" to "de-energize to trip." The UV/UF circuity will now fail in the safe position on loss of power.

D) Isolated the refueling water storage tank level inputs to the solid state protection system from the turbine field inputs. The design for this fuse modification results from the potential effects of a high energy line break in the turbine building.

E) Plugged an additional 3.17% of steam generator tubes, bringing the total effective plugging level to 6.92%.
