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

814 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?

Obtainment/procreation of weapons grade uranium. Conceptually speaking, nuclear bombs are simple. You’re creating a chain reaction with the enriched uranium by effectively smashing it together at a high speed. Fat man/little boy both had smaller explosives inside of them that were designed to set off the chain reaction required for the nuclear explosion.

Basically, you have to shave 3 neutrons off of naturally occurring uranium. This changes it from u238 to u235. This is a less stable version.

This is a very lengthy process that involves very specific and expensive and large equipment
