To the best of my knowledge, no, because atomic weapons got created under circumstances outside those an SRO could do much about, namely total war. That being said, an SRO might be able to spread ideas prior to total war that would increase the chance of researchers intentionally avoiding success the way, as I recall but may be totally wrong about this, it appears some German scientists working on nuclear weapons intentionally sabotaged their own efforts.
Would something like this have substantially impacted nuclear weapons research in any way?
