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 global energy crisis and climate change pose significant challenges for the future of humankind. To address these issues, clean energy sources are being promoted, with nuclear energy being an effective solution. The development of fission reactors and the promising advancements in fusion reactor technology provide potential solutions. However, challenges related to security and costs remain. This study focuses on the interaction between 55Mn and protons at 14.7 MeV using Monte Carlo simulations. Various Monte Carlo codes, including TALYS-1.96, GEANT4 (for GEometry ANd Tracking), PHITS-3.31 (for Particle and Heavy Ion Transport Code System), SRIM-2013 (for Stopping and Range of Ions in Matter), and ATIMA v1 41 (for ATomic Interaction with MAtter), were employed to investigate different interaction mechanisms. The research aims to understand the impact of these interactions on reactor performance, particularly in the context of the fusion facility. Manganese-containing steels play a crucial role in enhancing efficiency, durability, and safety in fusion reactors. The findings contribute to ongoing research and development activities in the field of nuclear energy.
