CONDENSATE AND CONDENSER

Question 1

State the function of the Condensate System.

Answer 1

In conjunction with the Main Feedwater System, the Condensate System provides de-aerated water to the Steam Generators for Reactor Coolant System heat removal and secondary plant steam production in sufficient quantities for all normal conditions.

Question 2

State the purpose of the Condenser

Answer 2

Condenses the steam exhausted from the Low Pressure Turbines and Steam Bypass Valves
Collects water from various sources for re-use in the secondary systems

Question 3

State the purpose of the Low Pressure Feedwater Heaters

Answer 3

Provides preheating of Condensate water stream to raise cycle efficiency and reduce thermal shock to the Steam Generators.

Question 4

Identify the normal Condensate System flowpath.

Answer 4

Starts from the Condenser Hotwells,
through (two) Condensate Pumps,
through the Steam Jet Air Ejector (SJAE) and Gland Steam Condensers,
through the tube side of Low Pressure Feedwater Heaters 1A & B-3A & B
through the tube side of the A & B Drain Coolers,
through the tube side of Low Pressure Feedwater Heaters 4A & B to the Main Feedwater Pumps
