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.

The D-3He fusion reaction has been used to produce medical radioisotopes using the University of Wisconsin Inertial Electrostatic Confinement (IEC) Fusion Device. The high-energy 14.7 MeV proton generated from the reaction can activate materials for isotope production. The traditional IEC setup has been altered to generate medical isotopes using beam-target D-3He fusion. Beam target D-3He reactions in a thin-walled, water-cooled, stainless steel tube were used to create 13N, an isotope used in Positron Emission Tomography. At a maximum ion energy of 85 keV, 1.0 nCi of 13N was created as a proof of principle experiment. A scaled-up version of this concept may provide for a smaller, less expensive radioisotope generator for future commercial needs.
