Some things I keep wondering about is assuming if everyone returns to pre 2018 status quo:
1) What will become of the Khondab calandria? Was a replacement ever created for heavy water use? Is there one provided or available for light water? Is there any calandria at all?
There was a ceremony placing the lid and upper biologic shield a few months ago, implying something should be down there under it. Assuming it's for heavy water, will there another concrete pour? Is it possible that nothing of substance was done by Sallehi other than placing some equipment and a lid and overhead cranes and therefore it will not be any hindrance for jcpoa?
2) How will FATF fit into all of this and Iran's ability to facilitate transactions? Will there be a waiver for the time being or will it become a stubborn block from day one?
"Some things I keep wondering about is assuming if everyone returns to pre 2018 status quo:"
In all honesty I really dont think theres much chance of that happening,at least if one is inclined to take the us and its eurovassals at their word.
"1) What will become of the Khondab calandria?"
If you mean the original,well in a truly astounding piece of stupidity it was filled with concrete with only a promise,worthless as it turned out,of a new redesigned smaller replacement using enriched fuel.
" Was a replacement ever created for heavy water use? Is there one provided or available for light water?"
No and No.
Theres very little information as to whether work on designing a new smaller enriched fuel replacement core ever even got underway,its quite possible that this was intended to be just like the space program ie just left to rot as another freebee to rouhanis bffs in the west.Ironically the chump regime in an act of unbelievable stupidity cancelled the waiver for the chinese firm that was supposed to provide some assistance with the redesign,this provided iran with the perfect excuse to revert to the original larger natural uranium fueled core especially since it had been revealed that iran supposedly had imported enough materiel for a second calandria,but sadly nothing has been done since then,at least that we know of.....
"Is there any calandria at all?"
NO.
Salehi
claimed that work had been carried out on the second cooling circuit,but then this clown also claimed back at the end of 2019 that the reactor would be operational by march 2021[LOL!!].I think its painfully obvious that little to no work has been carried out there for the last several years ie since the beginning of the implementation of the jcpoa basically.......
2)"How will FATF fit into all of this and Iran's ability to facilitate transactions? Will there be a waiver for the time being or will it become a stubborn block from day one?"
Something tells me that in the [unlikely?] event that the jcpoa is somehow salvaged,then I certainly dont see the us or its eurovassals allowing something like the fatf to put it all at risk again,because at this point this really will be the very last chance for the jpoa,never mind the possibility of any future deals........So I suspect that iran would be quietly returned to the grey list under some face saving pretext.
Still with all that being said,one should never underestimate the stupid self destructive tendencies of the west.......and sadly I say this as a westerner.
