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.

Radioactive 16N and 19O in the Tsing Hua Open-Pool Reactor, produced from 16O(n,p)16N and 18O(n,γ)19O reactions, respectively, have been measured using a rapid sampling device and gamma-ray spectroscopic systems. The radioactivity of the 7-s half-life 16N and 27-s half-life 19O in the pool water are monitored in the power range from 1 W to 1 MW. The three-dimensional concentration of these radionuclides in the water coolant is also contour mapped down to the detection limit of 10 Bq/ℓ. The spatial distribution of the short-lived radionuclides in the reactor pool, resulting from both the neutron flux distribution and heat transfer characteristics external to the core, is discussed for reactor operation at various power levels.
