Dear Mr. Musolf:

SUBJECT. GENERIC LETTER 88-03, "STEAM BINDING 0F AUXILIARY FEEDWATER PUMPS" (TAC NOS. 67262 AND 67263)

On February 17, 1988, Generic Letter 88-03 was issued and requested all licensees of operating PWRs and holders of construction permits for PWRs to

. confirm that appropriate procedures are in place, and will be maintained, to minimize the occurrence of steam binding of the auxiliary feedwater (AFW) pumps. The procedures require monitoring fluid conditions within the AFW system each shift during times when the system is required to be operable, c and recognizing steam binding and restoring the AFW system to operable status

.# should steam binding occur.

Your response, dated May 13, 1988, confirmed that you have in place, and will maintain, the necessary procedures. We also agree with you that improved maintenance and testing will help prevent any increase in check valvc failure due to plant age. Thus, your response to Generic Letter 88-03 is satisfactory and no further action is necessary.

This completes our work effort under TAC Nos. 67262 and 67263.

Sincerely, e0

Dominic C. Dibnni, Project Manager Project Dirdctorate III-1 Divistor of Reactor Projects - III, IV, V
