I'd love for you to be correct. I think pulling out of the JCPOA was stupid, and I'd love to be able to point out there is no risk anyway. But...

> Iran has nuclear power plants though, and uranium enrichment is needed to fuel them.

They have a single commercial reactor[0], and it doesn't need the enrichment levels they are producing.

Most reactors are light water reactors (of two types – PWR and BWR) and require uranium to be enriched from 0.7% to 3-5% U-235 in their fuel. This is normal low-enriched uranium (LEU). There is some interest in taking enrichment levels to about 7%, and even close to 20% for certain special power reactor fuels, as high-assay LEU (HALEU).[1]

Iran has over 200kg(!) of 20% enriched uranium[2]. I guess it could be for an unbuilt, experimental reactor like they claim. It seems unlikely, since they haven't pursued any contracts for a reactor like that.
