      @wellerstein A question regarding the LANL photos of Daghlian and Slotin accidents mockups: did they use actual Pu-239 cores to film them?

      @wellerstein Or just precise copies made of non-fissile material?

      @pfc_joker I'm not sure. It could be a dangerous game to mockup an accident situation with the same materials!

      @wellerstein LA-13638 mentions a "reenactment" and a "rerun", the latter producing about 6×10^15 fissions.

      @wellerstein If it is the same, then I guess those are the only photos of actual weapon cores ever declassified? Or are there other?

      @pfc_joker The "cores" in those photos are the right measurements — and the only ones I've ever seen declassified.
