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.

An evaluation is made of variations in reactor physics and engineering parameters during the core lifetime (100 000 MWd/mt) for a large 1000-MW(e) fast-thermal coupled reactor containing oxide fuel material. The analysis includes a comparison between the thorium and plutonium breeding cycles, as well as an estimate of the effects of several types of fuel management on reactor design variables. While the analysis indicates poor breeding characteristics for the particular design considered, the calculational methods developed and the relative parametric trends computed are of more general applicability.
