Figure 10.4.8-1—Steam Generator Blowdown System Discharge and Cooling and Figure 10.4.8-2—Steam Generator Blowdown Demineralizing System Flow Diagram provide schematic diagrams of the SGBS. Each SG is equipped with its own blowdown line with the capability of blowing down the hot leg and cold leg of the SG shell side. (The hot and cold legs are blown down at low plant loads; otherwise, only the hot leg is blown down.) The blowdown is directed into a flash tank where the flashed steam is returned to the cycle via the deaerator/feedwater storage tank. The liquid portion flows to heat exchangers cooled in two stages by the main condensate system in the first stage and the component cooling system in the second stage before going to the SG blowdown demineralizer. The SGBS also conveys the water from the exit of the SG blowdown …
