includino tho second valve which is 'normally closed or capable of automatic closure when the safety function is required."
(b)
"The AFW system boundary shall also include any portion of-branch pipino that is structurally coupled to the AFW system boundary such that the seismic response. of the branch pipino 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."
