<Gun-type fission weapons> are the simplest approach and they work with <Uranium-235> bombs as you can ignite it with just one explosion.

But <Gun-type fission weapons don't work with plutonium>, and <weapon grade Plutonium is cheaper than weapon grade Uranium>, so it wasn't much used.


Gun-type fission weapon

Because you can generate <plutonium-239> from <uranium-238> in a <breeder reactor>, and then separate the <plutonium-239> from the <Uranium> simply by using <chemistry> methods because you've created an element with different valence electrons.

Isn't it somewhat funny that it is easier to purify a synthetic element than a naturally occurring one?
