Uranium chemistry is covered in this lecture with an emphasis on separations and synthesis for the nuclear 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.
Just finished the lecture and the Quiz for Lecture 12. Very interesting.
ReplyDeletethanks for the comment. The unique aspects of the actinides will be highlighted in the upcoming lectures.
DeleteJust submitted the quiz. This was a very interesting lecture.
ReplyDeleteSubmitted the quiz and finished the lecture. Thanks!
ReplyDeleteFinished the lecture and the Quiz. I watched the lecture on the youtube channel for once and the slides looked a little different but the material was essentially the same. The calutron for separating isotopes was pretty interesting.
ReplyDeleteFinished the lecture and submitted the quiz. It was very interesting to see the methods of separating the different isotopes of uranium. It was nice hearing about the deposition of uranium metal because Dr. Hatchett used that research to give an example talk for senior seminar.
ReplyDeleteThe quiz was pretty easy. I think it was basically all covered in the first few minutes of each video. It was nice being able to finish the quiz so quickly so I could focus more on the lecture then figuring out the answers.
ReplyDeleteI have completed and submitted the quiz. It's nice to see that as technology is constantly evolving, we are still finding more ways to efficiently separate uranium isotopes, and it's going to keep getting more interesting as time goes on.
ReplyDeleteJust finished the lecture and quiz. This lecture was extremely useful and I wish I had watched it before attending the seminar on spin-phonon interactions in UO2. It was very cool to see how UO2 has different heat capacities at different temperatures after learning a little about the thermal lattice conductivity. Really awesome stuff!!!
ReplyDeleteFinished the lecture and submitted the quiz. It's nice to work with some familiar material such as redox reactions and I enjoyed learning about the real world applications of uranium.
ReplyDeleteI finished the quiz and lecture, it was interesting to finally learn about uranium more in depth and its chemistry
