I know diesels sometimes have the main induction there so maybe the SSN is running its diesel backup when in port for electricity?

what i saw was a big cloud of what looked like steam venting from the aft end, top, side of the sail...

there are a few vents there (at least they look like vents of some sort), and i was wondering what that was...

Thatâ€™s where the snorkel is located, they donâ€™t need to deploy it fully to use it, they can just poke the top part of the mast out of the casing. I know one story about a harbor pilot who saw diesel smoke coming out of the snorkel mast and he assumed it was how they get rid of the steam from the nuclear reactor.

Yes, and one time we were using our diesels to help charge the battery while alongside the pier (shore power wasn't enough). Our old diesels made lots of black smoke when they were fully loaded. The squadron watch officer called us up and asked if we needed any help with our fire

Beautiful shot there Bill! I always loved the scenery in the Bremerton/Bangor area.

It's the diesel exhaust, mixed with water for various reasons - that's why it doesn't look like a car's exhaust.

I remember Frank Kulick telling me that they had to run the diesels about every week or so just to make sure they were operating properly. I believe he was refering to the Improved 688s.

The problem comes when the wind blows it over the snorkel which fills the boat with smoke.

It's SOP for all nuke boats. The diesels are there for emergency use, you want to be sure they'll run when you need 'em
