I'm not knowledgeable enough about the exact process, and was pretty much hoping my post wouldn't get too much flak, as I would've to bail... Your post is extremely useful and very much appreciated.

The plutonium track & slow-burn reactor was completely new to me; most of what I have informed myself about was on the uranium enrichment controversy.

So, it just doesn't make any sense except if they want to control the level of enrichment, not targeting lightly enriched uranium for light-water reactors, but ultra-high enriched uranium for nukes.

That's similar to my own conclusion pretty much based on what I knew... The plutonium angle adds a whole other dimension. Now it's no wonder at all why the IAEA is at high alert.

The other bit, which I didn't want to put here since I know even less about it, was that the Iranian yellowcake of U3O8 is not pure grade enough caused by contamination of Be(?)-oxydes, which has a similar atomic weight as 235-U. But this falls into the categorie debunking the warmongers...
