Very, very basic overview of how a pressurized nuclear plant works, scanned from an old resource picture.

Rancho Seco has been long since decommissioned, but I figure this will give you an idea that there aren't any wizards or anything. Things have of course changed around a bit since the construction of the plant, but the basics are the same.

This had to be scanned as two different images and put together, so sorry about the obvious seam. I repaired it as best I could.

Figured technical resource stock was the best place for this, let me know if there's a better one.

I have a stock account now! Go Here for more stock photos from me!
