60% U-235 is far more than what is necessary for commercial power generation, and yet less than what it is necessary for a nuclear weapon (> 90%). This is a threat to make a bomb without actually crossing the line to actually making a bomb.
- devoutsalsa 6y agoIt seems that commercial reactors use 3% to 5% enriched Uranium. [1] Is there any practical reason to enrich Uranium to 60%? For example, is it cheaper to enrich the Uranium to 60%, and then use that as fuel for ~12 commercial reactors by diluting it down to ~5%?

- sokoloff 6y agoThis appears to be spending a lot of effort to concentrate uranium into a tidy, enriched package in order to provoke Israel into transforming that package into a significantly less concentrated and much less usable form.

- AdamJacobMuller 6y ago> Is there any practical reason to enrich Uranium to 60%? Yes. Going from 2% -> 90% first requires you to go from 2% -> 60% both in the mathematical sense (2->60->90) and in the process sense (it's a lot less work to from 60% -> 90% than it is from 2% -> 90%) and also in the sense that you to first develop the technology to enrich uranium to various levels, then develop the technology to enrich it to that level at scale, enriching to 2% isn't that hard, enriching to 60% is hard, enriching to 90% is harder but the leap from 2->60 is a lot harder than the leap from 60->90. In short, no, I don't think there is any practical reason to enrich to 60% unless your intention is to either enrich to weapons grade or as a threat to do so.
- Symmetry 6y agoWell, using more highly enriched uranium means you can make reactors lighter and more compact which is very important if you want to send them to outer space. I don't think Iran has any immediate interest in that but it's very much on NASA's radar.
- stunt 6y agoThere are some medical and research use cases, but I have no idea if Iran is advance enough to need that.
