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 series of simple laboratory experiments was conducted to test the feasibility of separation of plutonium-contaminated soil into plutonium-rich and depleted fractions. The purpose of the separation is to reduce the costs of managing plutonium-contaminated soil by separating a large fraction of the soil that can be disposed of as noncontaminated soil. Water-scrubbing (agitation) and washing of a sample of soil from the Savannah River Plant burial ground separated out a clay-silt fraction containing ∼95% of the plutonium, but comprising only one-third of the total soil; the remaining two-thirds of the soil was a sand that contained only ∼5% of the total plutonium. The technique appears to be adaptable to commercial sand scrubbing and classifying equipment, and should be generally applicable to soils of high quartz sand content such as the clayey sands typical of the coastal plain of the southeastern United States, but verification with other soils will require similar laboratory tests.
