==SUBJECT:==
DOCKET NO. 50-333/SPECIAL REPORT 93-005 NON-FUNCTIONAL FIRE DOOR FOR GREATER THAN SEVEN DAYS DUE TO PLANNED INOLUTION

==Dear Sir:==

The New York Power Authority (NYPA) submits this special report in accordance with Technical Specification 3.12.F.2 and 6.9.B.2. The report addresses a fire barrier door which was rendered non-functional for a period of greater than
<           seven days as a part of a planned evolution conducted during the Fall, 1993 Maintenance Outage.

== Description:==

The Turbine Building closed Loop Cooling System (TBCLC) was
:           removed from service to support maintenance scheduled during i           the Fall, 1993 outage. The station air compressors which supply service air, instrument air and breathing air are cooled by the TBCLC system and must remain available during all modes of plant operation.
4 To support continued availability of the station air compressors, temporary cooling was supplied from, and returned to, the plant screenwell area. The temporary cooling mechanical and electrical lines were routed through a turbine building fire barrier door, 76FDR-T-252-2, which reduced its effectiveness as a fire barrier.

                                                                    /

                      ' NONFUNCTIONAL FIRE DOOR FOR GREATER THAN SEVEN DAYS DUE TO PLANNED EVALUATION Page 2 Prior to routing temporary lines through the fire door, a continuous fire watch was established. The watch was provided specific instruction on how to disconnect all lines obstructing the barrier in the event of a fire.             A Limiting Condition for Operation was entered at 0225 hours on October 26, 1993, in preparation for establishing temporary cooling to the scation air compressors.
Maintenance on the TBCLC system was completed and normal cooling to the station air compressors was restored at 2345 hours on November 9, 1993. The temporary cooling lines obstructing the fire barrier door were removed and the door was restored to an operable condition. The Limiting Condition for Operation was in effect approximately 15 days.
This report is provided in accordance with Technical Specification 3.12.F.2 because the fire barrier door was non-functional for greater than seven days.
Action Taken:
The 15 day obstruction of the fire barrier door was a planned evolution. A temporary operating procedure was written to control the set up, operation and restoration of the temporary cooling system. Quick disconnect fittings were located near the fire door and the fire watches were knowledgeable in how to break the connections in order to close the door, in the event of a fire. All corrective measures were in place prior to actual obstruction of the fire door.
Cause:
The fire barrier door was inoperable for greater than seven days because of planned maintenance.
Safety Sionificancel The safety significance of this fire barrier obstruction was low. A continuous fire watch was posted for the duration of the evolution. The fire watch could have broken the fittings and cleared all obstructions in less than one minute, restoring the fire barrier to an operable condition in the event of a fire.
