Didn't read all posts but I doubt its been said, I've never even heard or seen it proposed but I dabbled in designing one myself.
To me it appears to be a huge metal sphere with a "barrel" extending outward from this dome/sphere. I believe it may have been used to attempt to
directionalize a nuclear explosive device. If you look at the top of the "dome" it appears to be blown outward from the inside. The scale does not
seem to be 10 m but much larger. In the 2007 images, I believe, the "containment"units had not been used as the top is still present however, in the
present pictures the facility looks blown outward from the inside then, due to the gaping hole, it was filled with sand over time. the explosion
within had to be enormous as the top of the "barrel" was blown off as well, up the entire length of it [barrel].
Eta: probably not though, just noticed they are flat.
