CHEM 418 Nuclear Chemistry, Winter 2018: Lecture 17 Separations

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 1 is 40 minutes, part 2 is 40 minutes, part 3 is 24 minutes, and part 4 is 30 minutes.  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. 
The lecture is assigned on Tuesday 27 February 2018 and due Tuesday 6 March 2018. The answers to the Lecture 17 PDF quiz will be posted Wednesday 7 March 2018.  A bonus question from this lecture, where has the PUREX process been used in Washington State.  You can answer in the quiz or on the blog.
