Salem AFW I can't reach my training contact. I'll try again Monday.

Upon further review of a single faulted SG and a P&ID of the AFW system from the FSAR, the discharge pressure of the effected MDAFW pump controls the AF21 valves for two SG's - the faulted one and other one.

Therefore, both AF21's would throttle closed to prevent runout in the MDAFW pump. To what extent they would close, I have no idea but the non-faulted SG would not be receiving 100% of the AFW flow from one MDAFW pump. I'll confirm this with my training contact as well as determining if/when the TDAFW pump would start in this scenario. Dave
