re: #395 wheat-dogg

10g of highly enriched uranium is not enough to make a nuke. That amount of uranium would occupy less than a cubic centimeter — smaller than sugar cube.

IIRC Trump and his minions managed to misquote the amount as 10kg, which would be an entirely different matter.

For reference, the Little Boy A-bomb carried 64kg of U235.

For a gun-type bomb, you need a lot more fissile material than for an implosion bomb. I’ve heard figures in the range of 28 to 64 kg of HEU. Pu is not possible to use because it’s too reactive.
For a implosion bomb however, you really don’t need that much, a 6.2-kilogram (14 lb) sphere of Pu and probably a similar mass of HEU is enough to make a nice big bang.
