I believe there's a pretty low chance of any meltdowns or nuclear events, due to so many fail-safes.

Thanks for sharing your opinion. But wouldn't it still be a serious safety hazard for the local population through contaminated air/water?

And if no radioactive material is set free, isn't it still available to keep producing nuclear weapons? According to a German article Iran is estimated to already have sufficient Uranium for 15 nuclear bombs.

In my simple mind that means you either have to directly destroy that material (and potentially expose millions of people to it) or if you just destroy the production facilities, you can only slow down the enrichment of further material without impacting the current capabilities. Do I oversee something?
