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.

In order to study the influence of yttrium on tritium behaviour in Li-Pb liquid alloys the coordination cluster theory was extended on the fourth-component systems. Using the developed approach the yttrium dependence on the thermodynamic activity of tritium in the whole concentration range of Li-Pb system were studied at 400–800°C. The yttrium displaces the concentration boundary which separates the regions with positive and negative deviations from ideality. Also, the yttrium addition has influence on threshold lead content, corresponding to conversation of the alloy from an exothermic to endothermic tritium occluder.
