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.

Postirradiation electrical resistivity changes have been found to be a measure of the irradiation temperature. Molybdenum and tungsten rod specimens were irradiated in the Experimental Breeder Reactor II to a neutron fluence of 1.1E+26 n/m2 (En > 1 MeV) simultaneously at six different temperatures, ranging from 455 to 1050°C. The postirradiation isochronal resistivity measurements made on the specimens showed a close relationship between the initial resistivity recovery temperatures and the original temperatures determined from the melt wires and SiC monitors irradiated in the same capsules. Experimental results indicated the possibility of molybdenum and tungsten wires as irradiation temperature monitors (molybdenum up to 850°C and tungsten up to ∼1400°C).
