...Mass-spectrometer enrichment looked much more simple and certain, just
difficult to scale up to the level needed, so it got pursued too (eventually
assisted by thermal diffusion), and it produced the first uranium bomb
cores. And in fact most of the early bomb cores came from water-cooled
graphite reactors producing plutonium, even though that required a lot of
work to develop implosion bombs (much trickier, much less well understood at
the start)...
Oak Ridge works.
Odd the first fission bomb (Alamogordo desert) was a "tricky" cast plutonium
implosion device. Not the simple uranium gun option: that was unleashed
above Hiroshima.
I have references of several of nuke test lists but does anyone have a
test-named list detailing uranium or plutonium was used?
Browsing I further read to my surprise uranium can be cast just like
plutonium into a sperical geometry for implosion devices.
