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 high fidelity wall-resolved Large Eddy Simulation has been performed for the flow through a guide plate of a Control Rod Guide Assembly (CRGA) at a hydraulic Reynolds number of 10,000. The computational mesh contains more than 1 billion computational cells and the simulation is run over six flow passes, which corresponds to almost 1 million time steps. The pressure forces are computed for all the rods and their average and rms values analyzed. This simulation can be either used to validate coarser LES/URANS computations, to understand the origin of physical phenomena such as deformations and vibrations or to model the pressure load along a rod.
