A number of different separation methods for radionuclides, with an emphasis on actinides, are presented. Solvent extraction, ion exchange, electrochemical, volatility and ionic liquid methods are discussed. The fundamental concepts are provided with specific examples on the nuclear fuel cycle. Ideas and concepts for advanced separations are given. Details are provided for the different separation routes discussed. The PUREX process is described. Examples are given for TRUEX and TALSPEAK separations. Specific examples for actinide separations are provided. Part 4 is a summation lecture on transuranic separations that are drawn from the Np, Pu, Am, and Cm lectures. Part 4 is meant as a review and provides a compilation of separation methods, the bulk can be skipped, but examples of questions are provided at the end of the lecture.
Finished the lecture and quiz. It's interesting to see that the different metallic fission products are distributed uniformly in the lattice of UO2.
ReplyDeleteYes. The metallic phases are not mobile in the fuel. It would be interesting to separate them and see if they have any uses. The metallic phase elements, Mo, Tc, Ru, Rh, Pd, certainly have interesting catalytic properties.
ReplyDeleteLecture and quiz completed.
ReplyDeletethanks for the comment and the quiz!
DeleteFinished the lecture and the quiz. I liked learning how UO2+x potential and temperature affected the composition of the fuel.
ReplyDeletethis is a feature that can be used in other fuel forms, including carbides, halides, and nitrides.
DeleteLecture finished and quiz submitted.
ReplyDeleteJust finished the lecture and submitted the quiz!
ReplyDeletethanks!

ReplyDeleteFinished the lecture and submitted the quiz. Interesting to learn about how some fission products migrate toward grain boundaries after formation.
ReplyDeleteYes. The chemistry of the elements continues in the fuel. The unique conditions can drive interesting properties.
DeleteFinished lecture and quiz.
ReplyDeletethanks for the response
DeleteLecture finished and quiz submitted!
ReplyDeleteCompleted
ReplyDeleteDone with the lectures. The part about processing Plutonium and its extraction from molten salt was pretty interesting. I like how Calcium can be recycled in DOR and I was wondering what kinds of electrodes in the electrolysis cell could withstand such a high temperature system?
ReplyDeleteGreat question about the electrodes. Carbon has been examined but they are not robust. Pd and similar metal work but are expensive.
DeleteJust finished the lecture and quiz. It was really interesting to see a connection between basic lab techniques from previous courses being built upon in this lecture!
ReplyDeleteAlways happy to see the links with other lectures
DeleteFinished. I feel like part of that was just a review.
ReplyDeleteThe 4th part is a review. I believe this was stated in the lecture and it is written in the lecture description.
DeleteJust finished the lecture and quiz. After Dr. Paviet-Hartmann's presentation on Friday, it was very interesting to learn more about the PUREX process.
ReplyDeleteThanks for making the connection with the lecture on Friday!
DeleteFinished the lecture and quiz, it was nice to see it all summed up together in the end
