e Response to Draft SER, Open Item 20, Parts 3 & 4 20.
Section 10./.9 - Auxiliary Feedwater System - The applicant has not verified... (3) that adequate suction is available to prevent AFWS pump damage during transfer to the nuclear service water backup water source (Recommendation GL-4 of NUREG-0611); (4) that air binding of AFWS pumps does not occur prior to tran; ferring pump suction supply.
Response
Adequate suction is available to prevent auxiliary feedwater pump damage during suction transfer to nuclear service water. Air binding of the pumps will not occur prior to or during transfer. Calculations were performed to determine worst case pump suction conditions during transfer. These worst case pump suction conditions were reviewed by the pump manufacturer and were found to cause no pump damage and no air binding.
