YFS III ywcomplete EXPECTEO SUSMISSION OATEI ivO ABSTRACT ILimit to /400 /peter, l,e., epproximetely IIINen rlnple rpsCe tyPewritNn linn/ (181 On March 23, 1988 and March 25, 1988 it was determined that problems documented (on March 18, 1988 and March 24, 1988) with regard to ll Plant Technical Specification fire penetrations were reportable under 10CFR50.73 (a)(2)(i). The penetrations were impaired such that they would not qualify as a three-hour fire barrier. The penetrations are located in the Diesel Generator and Reactor Buildings.

The problems were identified during the performance of ongoing physical walkdowns of all accessible Technical Specification walls and penet'rations as further corrective action committed to in LER 87-030.

As required by the Plant Technical Specifications, the penetrations were placed on an hourly fire tour. Further corrective actions include 1) preparing Maintenance Work Requests (MWRs) to repair/seal the penetrations, and 2) completing the 100K review of documentation and physical walkdowns of all accessible Technical Specification walls and penetrations. At the completion of the review and walkdowns, a supplemental report describing any further deficiencies discovered will be submitted.

The cause of this event is currently under investigation.

It was determined that this event did not affect the health and safety of either the public or Plant personnel due to the fire protection design of the fire areas involved.

Event Descri tion On March 23, 1988 and March 25, 1988 the following problems which were documented with regard to Plant Technical Specification fire penetration seals were determined to be reportable under 10CFR50.73 (a)(2)(i).

a) On March 18, 1988 it was documented on a Plant Nonconformance Report that:

Fire seal penetrations D101-3002- and D101-3003 (Diesel Generator Building 441 Elevation) each had a non-approved fire configuration type ~lug installed (holes had been drilled through the center and filled with 'All Thread" ).

~ Fire seal penetrations D102-3002 and D102-3003 (Diesel Generator Building 441 .Elevation) each had a non-approved fire configuration type (non-ferralloy) plug installed, and the penetrations were not 'listed in Plant Seal Tracking'System (PSTS) data base. 'he

~ Fire seal penetration D104-3063 (Diesel Generator Building, - 441 Elevation) was impaired in that the seal depth was less than required.

~ Fire seal penetration D113-2012 (Diesel Generator Building - 441 Elevation) was impaired in that through and the penetration not re-sealed.

it appears that a cable had been pulled b) On March 24, 1988 it was documented on a Plant Nonconformance Report that:

Fire seal penetration R116-3003.9 (Reactor Building - 422 Elevation) was impaired in that it appears that a cable had been pulled through and the penetration not re-sealed.

t Fire seal penetration R116-3003.10 (Reactor Building - 422. Elevation) was impaired in that the plug had a drilled hole through its center, and the penetration was not listed in the PSTS data base.

Fire seal penetration R116-3011.4 (Reactor Building - 444 Elevation) was impaired in that the seal depth was less than required.

Fire seal penetration R116-3011.6 (Reactor Building - 444 Elevation) was impaired in that the plug had a drilled hole through its center, and the penetration was'not listed in the PSTS data base.

Fire seal penetration R410-4004.7 (Reactor Building - 522 Elevation) was impaired in that it appears that a cable had been pulled through and the penetration not re-sealed.

The problems were identified during the performance of ongoing activities associated with further corrective actions committed to in a previous LER (87-030, "Upgraded Plant Technical Specification Fire Wall not Constructed to gualify as a Three-Hour Fire Barrier and Wall Penetration not Sealed" ). Specifically, the Supply System committed to perform a 10(C review of documentation, and physical walkdowns of all accessible Technical Specification walls and penetrations, to determine the adequacy of PSTS. The problems noted in this LER (88-008) were discovered during the ongoing physical walkdowns.

The cause of this LER is currently under investigation.

Immediate Corrective Action As required by the Plant Technical Specifications, the penetrations were placed on an hourly fire tour.

Further Discussion and Corrective Action a) Further Discussion

~ Fire seal penetrations D101-3002, D101-3003, D102-3002 and D102-3003 are located in Fire Area DG-V (1B Diesel Oil Tank Pump Room).

o Fire seal penetration D104-3063 is located in Fire Area DG-I (HPCS Diesel Generator).

~ Fire seal penetration D113-2012 is located in Fire Area DG-III ( 1B Diesel Generator).

o Fire seal penetrations R116-3003.9, R116-3003.10, R116-3011.4 and R116-3011.6 are located in Fire Area R-IV (RHR Pump Room Rl, Pipe Chase and RHR Heat Exchanger "B" Equipment Room).

~ Fire seal penetration R410-4004.7 is located in Fire Area R-VIII (MCC Room Division 2). I b) Further Corrective Action

~ Maintenance Work Requests (MWRs) were written to repair/seal the penetrations.

~ The penetrations which were not previously included in the PSTS data base were added to the data base.

~ At the completion of the 100% review - of documentation, and physical walkdowns of all accessible Technical Specification walls and penetrations, a supplemental report describing any further deficiencies discovered will be submitted.

a) Fire Areas DG-I, DG-III and DG-V Smoke from a fire would activate one or more smoke detectors, which would alarm in the Control Room. The fire brigade would be dispatched and take appropriate action in accordance with the pre-fire plans and emergency response procedures. Manual hoses are available.

The thermal detection system would sense a high heat condition and activate the pre-action sprinkler system. Automatic spray heads would fuse and control the fire.

b) Fire Areas R-IV and R-VIII Smoke from a fire would activate an ionization detector, which would alarm in the Control Room. The fire brigade would be dispatched and take appropriate action in 'ccordance with the pre-fire plans and emergency response procedures. Manual hoses are available.

In addition, Fire Area R-IV has a low fire loading and, as a result, the probability of a fire spreading is considered remote.

Accordingly, this event did not affect the health and safety of either the public or Plant personnel.
