  1. Putting my chemistry hat on -- yes, it fits -- your reasoning about enrichment is way, way off. So, stop right there. The way it works is by PARTITION -- not picking this or that 'coin.' Partition is bogged down at start by the huge fraction of 'dead' 238. It clogs up your process flow. All of your pipes, equipment -- everything -- has to be sized to handle a vast flow of 'inerts.' The partition function has its best economics when your centrifuges// partition function is not clogged with inerts... so the best process stream economics shows up around 60% enrichment. However, and this is where you started drifting off, as the percentage climbs up towards 70, 80 90 -- the partition function cuts against you. Now, getting RID of the 238 -- what you've been doing all along -- is starting to choke on the high fraction of 235 in the process stream. THIS is why you keep reading that atomic scientists decide to stop at 80% or 90%. BTW, Little Boy was an 80% device. I have no idea where 90% came from. Cost EXPLODES exponentially as you try and attain higher purities. The Iranians are doing exactly what one would do to craft an Atomic Bomb PROGRAM. They know that IF they ever announce that they've got a few -- Jerusalem will attack FOR SURE. That's why they are staying on the cusp. Beyond that, Tehran has lost a LOT of critical atomic scientists. Most by way of never hooking into their program -- not assassination. Israel has simply deterred them. This presentation is not up to your usual standards. The mullahs are going to keep on keeping on -- always staying on the cusp -- until they have so much very highly enriched 235 that they can break on through to Little Boy, PDQ. Here's the kicker. Little Boy needs a B-29 to deliver it. It's NOT suitable for ordinary missiles. The Soviet early era bombs were so heavy that Korolev built rockets sized for them. This baffled the Americans during the space race. Later, due to GRU spying, the Soviets were able to shrink their nukes. Costs plunged. So by the mid seventies, bomb counts went past ten-thousand, way past.
