This lecture is in two parts. Uranium chemistry is covered in this lecture with an emphasis on separations and synthesis for the nuclear fuel cycle. Uranium is introduced with an overview of its chemistry for the fuel cycle. The solution chemistry of uranium is explored, focusing on uranyl. The molecular orbital of uranium is described. Separation of uranium by solvent extraction and ion exchange is presented. The enrichment of uranium from the uranium hexafluoride species is discussed, including diffusion, centrifuge, and laser methods. Oxide species of uranium are presented. Due to its potential as a nuclear fuel, the synthesis and properties of uranium metal and alloys are described in detail. With three different phase, the uranium metal exhibits more complex electronic behavior than the metals of the lighter actinides, a trend that continues to plutonium metal.
I was doing the PDF Quiz and there were no automatic checkboxes for question 1. Can we just put our own checkmarks next to the answer?
ReplyDeleteI am having the same problem as Gabe, must be a universal issue
ReplyDeleteLet me fix that
ReplyDeleteError in PDF quiz fixed. Thanks!
ReplyDeleteWhen it is said that certain compounds can have a large number of phases, what causes these changes with the changes in temperature?
ReplyDeleteelectron configuration. The heat can cause electrons to occupy different energy states and different orbital, think about the Boltzmann distribution.
DeleteLove learning about Uranium. Just shows it's not as scary as everyone thinks.
ReplyDeleteI agree Remy! Before this program never studying uranium I assumed it was sooooo horrible this was a really cool lecture I enjoyed it!
Deletethanks for the comments. the f electrons are cool!
DeleteI really enjoyed this lecture as well being that I learned this in Chem 2 so the quiz was a breeze! Really enjoyed learning it again!!
ReplyDeleteGreat to hear about using other chemistry knowledge!
