Dear Mr. Stolz:

Three Mile Island Nuclear Station, Unit I ('IMI-1)

Operating License No. DPR-50 Docket No. 50-289 Technical Specification Change Request No. 97 Rev.1 Correction On December 1,1983, Technical Specification Gange Request No. 97, Pcv.1 was subnitted requesting amendment to Appendix A of Operating Liwnse No.

DPR-50. The requested change would incorporate scme Appendix R nodifications and operating experience into TSCR 97.

TS 3.18.7 Fire Barrier Penetrationsand TS 4.18.7 Fire Barrier Penetrations inadvertently are said to apply to all fire barrier penetration seals in fire zone boundaries. The applicability should be for all fire barrier penetration seals in rated fire boundaries. This change does not affect the previously submitted Safety Evaluation. The corrected pages are enclosed for your convenience.

Sincerely,

! . D. !!anl:.,

( 4' l 3.18.7 FIRE BARRIER PENETRATIONS APPLICABILITY: All fire barrier penetration seals (including cable and pipe penetration barriers, fire doors and fire danpers) in rated fire boundaries protecting safety related areas shall be functional at all times when equignent on either side of the barrier is required to be operable.

OBJECTIVE: To assure the effectiveness of barriers.

SPECIFICATIONS:

3.18.7.1 All fire barrier penetration seals protecting safety related areas shall be functional or action shall be taken as described in 3.18.7.2.

l 3.18.7.2a. With one or more of the above required fire barrier

!- penetration seals non-functional, establish a fire patrol to inspect at least one side of the affected penetration l once per hour during refueling shutdown, cold shutdown, heatup/cooldown, and hot shutdown. At all other times a continuous fire watch shall be posted on one side of the affected penetration within one hour.

3.18.7.2b. Restore the penetration seal to an OPERABLE status within 14 days or, prepare and subnit a Special Report to the Ctmnission within the next 30 days outlining the action to be taken, the cause of the inoperability and the plans l and schedule for restoring the systen to an OPERABIE status.

BASES: h e functional integrity of the fire barrier penetration seals ensures that fires will be confined or adequately retarded frcan sprmMng to adjacent portions of the facility.

h is design feature minimizes the possibility of a single fire rapidly involving several areas of the facility

prior to detection and extinguishment. % e fire barrier j penetration seals are a passive elenent in the facility l

fire protection program and are subject to periodic inspections.

! During periods of time when the seals are not functional, l a roving or continuous fire watd1 is required to be main-tained in the vicinity of the affected seal until the seal is restored to functional status as described'in specification

FIRE BARRIER PENETRATIONS APPLICABILITY: All fire barrier penetration seals (including cable and pipe penetration barriers, fire doors and fire dampers) in rated fire boundaries protecting safety related areas shall be functional at all times when equignent either side of the barrier is required to be operable.

OBJECTIVE: To assure that the effectiveness of fire barriers protecting safety-related areas is maintained.

SPECIFICATION:

4.18.7.1 Fire barrier penetration seals and fire dampers shall be verified to be functional by a visual inspection:

a. At least once cadi refueling interval; and

b. Prior to declaring a fire barrier penetration seal or fire damper functional following repairs, main-tenance, or initial installation.

4.18.7.2. Fire doors shall be verified to be functional by a visual inspection:

a. At least weekly for doors that are locked closed to verify that they are locked closed and free of obstructions.

b. At least daily for doors held open by autmatic release mechanisms to verify that the doorway is free of obstructions.

c. At least daily for doors neither locked nor supervised to verify that they are in a closed position.

d. Prior to declaring a fire door functional following repairs, maintenance, or initial installation.
