watched it and thought it might make some interesting, not political light conversation.

Starlite if i remember correctly.
Doesn't explain the fissionable materials detected in Australia. I thought it was a joint Israel/South Africa test.

Vela sounds like a Bolide ablating in the upper atmosphere. Significantly, there was a double flash, like burn up on reentry and they didn't recover any airborne rads. IOW, non nuclear.

That one us underscored by all the times nuclear material is stolen and goes unrecovered.

Yeah, they recovered it from the ventilation filters, the workers clothes, the walls, pretty much everything in the plant was covered in the fissile material - it accounted for the missing fissile material.
Those plants had pretty damn lax safety, even more so in the early years of Nuke making, but it didn't get much better all the way up into the 90s.
Later, Fernald extracted uranium from scrap metal or recycled material (i.e., floor sweepings, dust collector and production residues) received from on-site operations and other nuclear weapons complex sites.
Incoming material was weighed, sampled, dried, ground and classified using crushers, mills and samplers in Plant 1, and then drummed and transported to Plants 2&3, where the material was converted to uranium trioxide. Initially, the material was dissolved in nitric acid to produce a crude uranyl nitrate (UNH) solution for solvent extraction purification. Purified UNH was then concentrated by evaporation and thermally denitrated to uranium trioxide, called orange oxide. The orange oxide was either shipped to the gaseous diffusion plant in Paducah, Ky., or was transported to Plant 4, where it was converted to uranium tetrafluoride, called green salt, for reduction to metal.
