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 continued development of science, engineering, and technology to support nonproliferation policy is instrumental in allowing states to verify compliance with nonproliferation treaties, providing effective and efficient ways to implement domestic and international nuclear safeguards, and preventing non-state actors from developing nuclear weapons or acquiring weapons-usable nuclear or radiological material, equipment, technology, and expertise. This technical session will focus on new research that supports different aspects of nonproliferation policy.
