Dear Mr. Ippolito:

N' During a recent I6E inspection by Mr. W. H. Miller, Jr., of Region II, concerning the Brunswick Steam Electric Plant (BSEP) Fire Protection Program, Unresolved Item (50-324/81-23-05, 50-324/81-23-05) was identified in regard to fire barriers located between service water pumps. The concern noted in this unresolved item was the absence of por-tions of fire barriers for conventional service water pump 1A and nuclear service water pumps 1B and 2A.
The lack of documentation showing that these barriers were no longer required Icd to this unresolved item.
The requirement for these fire barriers was referenced in the NRC Fire Protection Safety Evaluation Report dated November 22, 1977 (refer to Sections 3.1.9 and 5.7.6).
In a joint meeting on March 9, 1979, between NRC staff and BSEP personnel to discuss the fire protection modifications at the Brunswick site, the requirement of these fire barriers was discussed. Prior to the meeting, it had been believed by NRC that the pump motors contained pressur-ized lubrication systems, the rupture of which would present a fire hazard to surrounding components. During this meeting, Mr. R. E. Porterfield, BSEP Site Engineer, explained that the lubrication system contained on these pumps was only pressurized to atmospheric pressure; therefore, fire barriers to prevent lubrication spray were not needed.
In addition, this portion of the service water intake structure is provided with 100% auto-matic sprinkler protection.
It was therefore concluded by the attendees that, based on the facts presented, these barriers were not necessary and could be removed. The minutes of this meeting by Mr. J. N. Hannon, NRC Project Manager for the Brunswick Plant, did not document this verbal ADOb concurrence.
