What’s the most difficult question you’ve been asked as a maintenance instructor?
Blye Widmar
"Where are the prints?!"
This was the final question in an onslaught of verbal feedback, comments, and critiques I received from my students back in 2019. I had two years of instructor experience and was teaching a class that had been meticulously rehearsed in preparation for an accreditation visit. I knew the training material well and transferred that knowledge effectively enough for all the students to pass the class. As we wrapped up, I asked the students how they felt about my first big system-level class, and they did not hold back.
“Why was the exam from memory when we don’t work from memory in the plant?” “Why didn’t we refer to the vendor documents?” “Why didn’t we practice more on the mock-up?” And so on.

Proposed empirical correlations of the extractive distribution and overall mass transfer coefficients in the Purex H2O-HNO3-U(VI)-30% tri-n-butylphosphate/dodecane liquid system are compared with experimental data. The roles of eddy diffusion and interphase chemical reactions in the transfer kinetics are discussed. These equations are incorporated into the DYNAC computer model and applied to the analysis of a plantsized pulsed-column connection. The predicted profiles of the uranium concentration and the temperature are in good agreement with the experimental data under steady-state and transient operating conditions. Hence, the kinetic correlations have proven useful in expressing the chemical and diffusional nature of solute transfer.
