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
