Document Control Desk Vashington, DC 20555 Gentlemen J. H. Farley Nuclear Plant - Units 1 and 2 Hiniflov Evaluation - NRC Bulletin No. 88-04 Alabama Power Company tesponded to NRC Bulletin No. 88-04 by letter dated July 8, 1988. The response provided a description of the miniflov system, a description of hov pump-to-pump interaction is precluded, and an explanation of the adequacy of the miniflov system for safety-related pumps.

It was recently noted that the containment Spray portion of the attachment is in error.

The Containment Spray description, in the Pump-to-Pump Interaction paragraph states, "Surveillance procedures do not provide for operating pumps in parallel." However, the surveillance procedure for verifying automatic start of the containment spray pumps is perfccmed each refueling outage and allovs pump operation in parallel for up to one minute. Operation for up to one minute vill be incitided in the designer's review of the containment Spray system.

If there are any questions, please advise.

Respectfully submitted, k,
