How long does it take to build a nuclear bomb?

That’s enough to build one atomic bomb, if the uranium is further refined to make it weapons-grade — a process that could take just two to three months , says David Albright, a nuclear-policy specialist at the Institute for Science and International Security in Washington DC.

How long would it take for Japan to build a nuclear bomb?

6 – 12 months

How long would it take to build a nuclear bomb today?

Then eight or nine months to extract the Plutonium, design and build the bomb. That’s pretty fast too. Today, we might be able to do that a little faster too but not much. So, it took the Manhattan Project scientists about 2.5 years, so we might be able to do is in 2 to 2.5 years.

How much uranium does it take to make a nuclear bomb?

For nuclear bombs, that figure needs to be nearer 80 or 90\%. Get around 50kg of this enriched uranium – the critical mass – and you have a bomb. Any less and the chain reaction would not cause an explosion. You could use plutonium instead.
