Purposes of Condensate System

The purposes of the Condensate system are to: Condense steam from the main turbine and TDBFP and collect steam drains in to the main condenser.   Remove non-condensable gases from the main condenser. Purify and preheat water prior to injection into the boiler. Supply  the  driving  head to  pump water  from  the  main  condenser  to  the boiler.   Provide injection  path  for  High Pressure  Coolant Injection system  to  the bpoler Provide injection path for Reactor Core Isolation Cooling system to the  boiler.   Provide a path for returning Reactor Water Cleanup system to the boiler. There are the following system involved in condensate system. CST (condensate storage tank) Condenser Hotwell CEP (Condensate extraction pump) Main ejector Gland steam condenser Deaerator level control valve  Excess return to CST CEP minimum re-circulation line Drain cooler LPH-1 (Low pressure feed water heater-1) LPH-2 (Low pressure feed water heater-2) LPH-3 (Low pressure
