Air Cooled Condenser Vacuum Leaks

[JMSki]

Typically how long before an in-service ACC develops air in tube leakage?
Those that have experienced leakage do you have the ability to isolate a street - exhaust steam, air-ejector and condensate return so you can run at a reduced load?

There have been a number of papers EPRI conferences on this subject.
The units that I have seen have little provision for isolation of portions of the condenser.

Some of these units have struggled to meet required air leakage when new.
It is a lot of joints out in the open.

And don't get me started on keeping them clean.
