NN Asks: What did you learn from ANS’s Nuclear 101?
Mike Harkin
When ANS first announced its new Nuclear 101 certificate course, I was excited. This felt like a course tailor-made for me, a transplant into the commercial nuclear world. I enrolled for the inaugural session held in November 2024, knowing it was going to be hard (this is nuclear power, of course)—but I had been working on ramping up my knowledge base for the past year, through both my employer and at a local college.
The course was a fast-and-furious roller-coaster ride through all the key components of the nuclear power industry, in one highly challenging week. In fact, the challenges the students experienced caught even the instructors by surprise. Thankfully, the shared intellectual stretch we students all felt helped us band together to push through to the end.
We were all impressed with the quality of the instructors, who are some of the top experts in the field. We appreciated not only their knowledge base but their support whenever someone struggled to understand a concept.

The multiplication of 14-MeV neutrons in bulk beryllium has been measured using the manganese bath technique. Values of the multiplication have been obtained for beryllium samples of four thicknesses. Detailed calculations of the multiplication and all the systematic effects were made, utilizing a highly detailed three-dimensional model with the Monte Carlo program MCNP. The Young and Stewart and the ENDF/B-VI evaluations for beryllium were utilized in the analysis. Both data sets produce multiplication values that are in excellent agreement with the manganese bath measurements for both raw and corrected values of the multiplication. We conclude that there is no real discrepancy between experimental and calculated values for the multiplication of neutrons in bulk beryllium.
