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.

A Monte Carlo technique was developed for predicting the mode of energy transfer from fission fragments liberated within spherical solids to the fluid or neighboring particles in a slurry. Random location energy liberation for a large number of fissions within the solids and subsequent absorption was followed by means of a high-speed digital computer program. The fraction of recoil fragments and energy spectrum deposited in the fluid was characterized as a function of concentration and particle size of the solids.From ftom these results, a useful correlation equation was developed.
