Just to clarify the SONGS 1 issue.  The containment was a steel ball containment.  Eventually, someone figured out that the steel ball didn't really provide a whole lot of shielding, so the post accident shine doses were very high.  Then then added the concrete shield building around the steel ball. 

Here is a pretty cool picture of the containment being erected.

The following set of photos, taken during decommissioning, shows the shield building with the roof removed, and then with the shield building walls partially removed.  You can also see the covers over the holes in containment where the vessel and SGs were lifted out.

Decommissioning has now gotten to the point where the entire turbine structure is gone, almost all of the shield building wall is gone, and the steel ball is removed to ground level (or below).

Neat picture. Not much for shielding.

I enjoyed this statement: "At the north, a third reactor appears to be under construction, with the reactor dome partly completed and a turbine structure perpendicular lacking a turbine." 

Great pictures!

Center of the Rx vessel is exactly 1 mile from President Nixon's former Avenida del Presidente house. Unit 1's footprint will eventually be filled in with white sand to restore to "greenfield" status. On a clear day, we could see out north to Dana Point, south to Carlsbad, and all the sunbathers....
