Enclosure 1 of Generic Letter 81-14 (GL 81-14) oefines the auxiliary feedwater (PW) system to be cons'ioered as:

(a)

"The AFW system bounoary from suction to discharoe (including the w-ter source ano heat sink) shall include those portions of the system required'o accomplish the AFW system funct'on ano connected branch piping up to and including the secono valve which is normally closed or capable of automatic closure when the safety function is requireo."

,(b)

"The AFW system bounoary shall also include any portion of branch piping that is structurally coupled to the AFW system boundary such that the seismic, response of the branch piping transmits loads to the AFW system.

As a minimum, this includes the branch lines outside the AFW system boundary to a point of three orthooonal restraints."

(c)

"Allmechanical and electrical equipment, piping (e.g.,

instrument air.), conduits and cable trays, which are necessary or contain items which are necessary for the operation of the AFW system, shall also be considered."
