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.

Soxhlet-type leaching experiments were carried out for SYNROC-C specimens synthesized by three different methods; hot uniaxial pressing, hot isostatic pressing, and atmospheric sintering. The leaching solutions were analyzed by inductively coupled plasma spectroscopy and atomic absorption spectroscopy. When elements such as sodium, cesium, and molybdenum contained in the glass phase of SYNROC-C, they are leached preferentially at the initial stage of leaching. The difference in elemental mass loss between the three SYNROC-C specimens (10 to 102 g/m2) depends mostly on the amount of preferential leaching. The release of the above elements is controlled by preferential leaching at the initial stage and then by diffusion through the host crystalline phases. The other elements not found in the glass phase can mainly be controlled by diffusion.
