Encicsure 1 of Generic Lette. 81-14 (GL 81-14) defines the auxiliary fee: water (AFW) system to be considered as:
(a) "The AFW system boundary from suction to cischarge (including the water source and heat sink) shall incluce those portions of the system required to accomplish the AFW system function and connecteo branch piping up to and incluaing the secenc valve which is normally closed or capable of automatic cicsure when the safety function is required."
(b) "The AFh system boundary shall also incluce 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 incluoes the branch lines outside the AFW system boundary to a point of three orthogonal restraints."
(c) "All mechanical 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."
