       | It is absolutely insane that the government is allowed to be so
       | reckless with highly enriched uranium.

       | Also worth looking into the origins of Pakistan's nuclear
       | program.

         | Pakistan built their own uranium centrifuge plant:

       | 'Curious' that the US didn't move entire mountain ranges to find
       | the stuff... .

         | (Atomic Energy Commission report, 1966) and then adjusted by
         | CPI.

           | Huh, I'd've assumed it the other way around given the
           | infrastructure requirement at the time, but your cost sounds
           | a lot more likely given its provenance than the [now, i
           | realise belatedly, unvalidated] cost I Googled prior.

             | The mind boggles.

           | Exactly. They couldn't not investigate, but they also knew
           | where it went and didn't exactly want to dig too hard because
           | they might accidentally find too much evidence.

             | Oh, I don't know. Lacking implosive compression the

             | to have in mind, but rather a "demon core"-style radiation
             | accident. That said, it'd still be enthusiastically messy
             | albeit in a more limited fashion, and there'd still be no
             | reason for anyone to assemble the material that way - not
             | least for what grisly example became of the last guy who
             | took so little care.
             | 
             | Still, as you note, it's remarkable to think of the density
             | of the material - a soccer ball's worth that masses about
             | as much as _me_.

       | this kind of thing must have occurred in other nuclear programs?

         | All the other nuclear regimes around the world? Less so, I'd
         | imagine. They'd be counting their beans a bit more.

       | This story was back in the 70s. I'm sorry, my memory fails me
       | about any further details. It might or might not be related to
