Explain how this system interfaces with the Desuperheater feed system:
The Desuperheater Pumps take suction from the MFP Suction Header. The main feed line, under the boiler deck grating, sends a direct line to the desups as well tying in with the DSPumps discharge. The main feed line, under the boiler deck grating closer to #3 Boiler, sends a direct line which links up the #3 DS at Thompson Tunnel. The Thompson Tunnel line also loops back into the original DSPump discharge.
