While investigating this occurrence it was determined that per the 18 month firel 11l1l l barrier surveillance on Unit 2 completed 10/14/82, two other reportable, degraded fire barrier penetrations hadl l1l11 levisted. An unsealed conduit was identified during an NRC Audit exit meeting on 11/19/82. Other LERs con-l l111l leerning Unit 2 fire barriers include 82-029,81-042, 81-036,81-029, and 80-081.

initiated which should prevent recurrence. These include: 3) the design change package installation verification now includes a requirement to verify penetration sIaling prior to close-out of a job; 2) a review is presently being conducted of JNP0's " fire barrier degradation" SOER, to determine if their recommendations are applicable to AN0; 3) a request to the plant's engineering staff has been made to revise the design change procedure to specifically address fire barriers: 4) the Lic nsing Section is preparing a consolidated "ANO Fire Protection Program Description" in order to provide a comprehensive reference on fire protaction at AN0; 5) new drawings are being developed to explicitly delineata fire walls and

6) a walkdown of fire barriers is to be conducted in order to revise the fire barrier surveillance procedures.
