Can you make nuclear bomb without uranium or plutonium?

Assuming you mean, Can a nuclear bomb be manufactured apart from the standard bomb fuels, U-235 and P-239, the answer is: Yes. Thorium is suitable for bomb-making, by way of the proactinium-to-U233 decay chain. It has in fact been detonated a number of times in nuclear weapons tests. read more

Well, since you can’t make an atomic bomb using platinum, anyway, I think that can be discarded. If you mean uranium or plutonium, then the answer is yes. Thorium has been considered, but for technical reasons, although it is radioactive and a neutron emitter, it is not suitable for making a nuclear device. read more

"You cannot make a nuclear bomb without fissile material," says Andrew Furlong, of the Institute of Chemical Engineers. And for an average thermonuclear device, the necessary material is plutonium or enriched uranium. Uranium, a naturally-occurring heavy metal, comes as uranium 238 or 235. read more
