  Using the rule of thumb, anything heavier than iron requires energy input to fuse. So you lose energy fusing uranium.

  Serious answer: A huge negative amount. Anything above iron requires energy to fuse (which is why it produces energy from fission.) and I’m pretty sure nothing with 184 protons could be stable enough to count as being produced - the nuclei be more smashed apart than merging at that point.

  Ask Hiroshima and Nagasaki.

  In alphabetical order.

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

        Look at all these nuclear scientists on Lemmy.

        Sorry I meant Lithium Deuteride.

      For that matter, even the Nagasaki bomb (“Fat Man”) didn’t use Uranium at all - its fuel was Plutonium.

      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.

      Damnit, you’re right and I’m wrong!

    That’s fissed, not fused.

      I stand corrected, because I done forgetted.
