If North Korea is any clue, it’s going to be testing some bombs. Strategic patience my a- ! Thanks Obama.

Well, if it weren’t for them being raving islamic ***holes, it would be because you would prefer to use your petroleum reserves for lubricants, feedstocks and motor fuels or sell it to others for refining into same.

I vote we send them some depleted uranium.

Thank goodness the Brits blocked it last time.

U236 is not naturally occurring. It is created by U235 absorbing a neutron. This means the uranium being enriched had to been exposed to a neutron flux of some type - and most likely a reactor. The IAEA table for U236 neutron cross section is 5 barns for radiative capture which is more than 100 times less than the fission cross section for U235. See http://www.nuclear-power.net/nuclear-power-plant/nuclear-fuel/uranium/uranium-236/.

I'm actually very familiar with centrifuge and other types of Uranium enrichment.

Nice link - thanks.

So U236 are the U235 atoms that absorbed the Neutron and did not split and go boom. So U236 being present is evidence that fission had been going on most likely in a reactor.

Exactly...

When a neutron hits a U235 atom, a number of things can happen. The most productive is fission. But U236 production can occur too with about a 18% probability, if I remember correctly. That's what makes the Iranian Uranium feed to their centrifuges a little odd.
