How much more energy would you get if you fused uranium?

[–] [email protected] -5 points 4 days ago* (last edited 4 days ago) (13 children)

Ask Hiroshima and Nagasaki.

In alphabetical order.

Edit: oops, those are fission, my bad

Those are fission. Fusion bombs don't fuse uranium. They use a fission bomb to fuse Lithium.

Oh, they do, but not as the primary or secondary. You can wrap depleated uranium around the core to capture fast neutrons that are leftover from the rest of the process. Changing the number of layers is how you can dial in a desired yield.
