#2 Trust but verify. Are there going to be inspections? If so, who will inspect? The article didn't say.

#4 Natural uranium is .7%, or .007, u235 to unuseful isotopes.

If you start with 1000 kg raw ore, being 7 kg u235 and 993 kg U238, you would need to refine it down to 7 kg of u235 and 28 kg of u238, totalling 35 kg.

Which means processing some 993-28= 965 kg of material.

By comparison, at the end state, you have 90% U235, 10% U238, massing 7.8 kg. (roughly), and 992.2 kg of U238.

Which means:

20% refined is 965/992.2 is 97% of the way to a bomb.

Any mistakes in my math?

#5 Similarly, 7*20=140 KG, Which means for 5% material, you'd have 7 kg U235, 133 KG U238 and other, which works out to having processed 992.2-133= 859.2 kg out of 992.2

859.2/992.2= 86% of the work done.

#6 That's all back-of-the-envelope stuff. To summarize:

5% enriched: 86 % of the way to 90% enriched.

20% enriched: 97% of the way to 90% enriched.

#7 Sure hope they remember to add their boron & hafnium to the uranium before machining their core.
