It has certainly gone through to give the Iranians the ability to achieve nuclear weapons (intentionally? unintentionally? who knows?). I could offer a short lecture on this but I won't. Invite you to do some self-guided reading on how easy it is to make a nuclear weapon after you have two things: (1) large enrichment capabilities and (2) a nuclear reactor. Iran now has both. Normally, not just any reactor will do, and much of what has been done in the past has never confirmed that Iran's reactors could not be used to extract plutonium. You see, the U-238 isotope, when exposed to a nuclear fission cycle, does the same thing that other uranium isotopes will do: absorb a neutron into it's nucleus, and increase it's atomic mass by 1, become U-239, also known as plutonium. So no, you don't have to enrich uranium to weapons grade to make a bomb out of it (Iran's enrichment facility cannot enrich that high so everybody - fools - says "great, we're safe!"). You just have to enrich it (1) high enough to produce enough for a reactor cycle, and (2) to extract and isolate enough of the isotope U-238 after long exposure to the fission process.
If you were to do much reading about what the UN has done going back to the early 2000s, much of their efforts concentrated on determining that the Iranians did not or would not have the facilities to separate plutonium after fuel removed from reactors. This requires an irradiation process. However, that effort alone is enough to tell you that the UN would have been convinced that the Iranian reactor designs would have been either suitable for plutonium production or suitable for modification to that purpose. Fact is, plutonium is a natural by-product of the nuclear fission process, as all spent nuclear fuel from any conventional nuclear reactor will have probably around .8 or .9% Pu-239 in it. The world is very unsafe if Iran has the ability to separate plutonium.
I suppose I did give a short lecture. Sorry about that. And that's all I'm going to say on the subject, other than to note this describes the basic process the Israeli's used to "get the bomb."
