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.

Ion exchange on a potassium-exchanged natural zeolite at various temperatures is examined. The ions studied were cesium and cobalt, and the contact temperatures were 25, 60, and 100°C. The main focus of the work was to examine the use of natural zeolite as a direct means for the removal of radioactive contaminants. It was found that cesium was more selectively sorbed than cobalt and that higher amounts of both cations were taken up as the temperature of contact increased. The raw data could be correlated using a Brunauer-Emmett-Teller-type isotherm. The ion exchange equilibrium constants and activity of the sorbing ion on the zeolite were used in correlating the data. An Arrhenius behavior was suggested.
