In the auxiliary seawater circulating system, how many independent SSTG condensers are used?

• A. Five
• B. Three
• C. Four
• D. Six

Answer: (A)

Redundancy and cooling capacity in the auxiliary seawater system drive the number of SSTG condensers. Each SSTG needs a condenser to condense the exhaust steam using seawater, and having multiple independent condensers lets the plant keep generating even if one condenser is offline for maintenance or a fault. Five independent condensers provide enough cooling capacity to support the SSTGs and still allow work to be done on one unit without shutting everything down. That arrangement ensures you can operate, and service, the system without losing overall cooling capability.
