Eli5: Why is it so hard for a country to make a nuclear bomb?

790 viewsOtherPhysics

I’m assuming the science of making one is out there. Why then countries like Iran who so want to develop atomic weapons haven’t been able to do so?

It’s the fissionable material. The bomb part is pretty easy. The stuff that goes boom in the middle is hard to refine.

The powers that be keep a tight lid on all natural uranium sources. Nobody really wants this out on the open market.

The natural ore is mostly U-238 which won’t explode. Separating it out and getting the U-235 means you have to gassify it, spin it until the extra weight of those protons pull it down, and then siphon off the top. Re-solidify it, and pack it into pellets. The equipment to do this is more than just spinning a bucket over your head and people also keep watch on any country that buys the sort of stuff needed to make it. When Iran does this, Israel specifically goes out of their way to sabotage it. There are some wild stories in cybersecurity about it.
