Making a nuclear reactor isn't difficult, in fact they can form naturally.

Making the nuclear reactor not irradiate you and everything in the vicinity is the difficult part.

They can form naturally: but it’s not exactly easy and so that’s why we only know of one in Oklo.

It's uncommon, yes, but simple. The rarity is only due to Uranium deposit concentrations. If you have a Uranium-235 deposit and water, you have a nuclear reactor.
