Reactor containments

--- Quote from: BuddyThePug on Aug 31, 2005, 07:54 ---Your answer is incorrect. SONGS 1 was orginally built with the same famous white semi-spherical steel containment as D1G prototype, and several other reactors of the early 1960s.

There was, however, a commercial power nuclear reactor built with no pressure rated containment, west of the Rockies. Built before SONGS1. That's all the hint before Labor Day.

Yes it was built with it but I think you will find that it was not in the original design.

And where would we *find* that? It was built with one, and commercial plants built almost a decade earlier, like Shippingport, were designed and built with a containment. What causes you to think SONGS1 was originally designed with NO containment?

   Sorry, probably a bad question, I got this in the early 80's while working there from a reliable source. I declined to post other trivia questions because I could not find current information I should have done the same here. I would have liked to pose questions or post info on the S1W prototype building/containment but there is no source I could find. 
  Shippingport may be a bad comparisson as it was done in conjunction with the Navy as the first commercial power plant, and we know how conservative the Navy is with thier safety systems. I am curious about the date that containments were first required by the AEC/NRC I couldn't find that one either.
   I promise to be more carefull with future posts.

Already Gone:
Sorry trivia bufs but Shippingport was never a commercial power plant.  It did put power on the grid, but it did not have a license for commercial operation.  The first commercial power plant was Dresden 1, although Indian Point 1 claims this title also.
Dresden 1 is the one in the ball, as was Big Rock Point and some other old small units were.

Marlin:
I've always heard Dresden is the first commercially owned and operated plant but Shippingport was the first commercial plant. Licenses are for regulation not commerce, they did sell the power.
