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.

Calculations are made of 2.5-MeV neutron yields via D-D reactions from various beam line components, including beam targets and a neutralizer gas cell, and of x-ray generation from accelerator columns in deuterium beam injectors of various energies from 40 to 200 keV, with accelerator powers ranging from 2 to 20 MW per beam line. The calculated neutron intensities from the neutral beam injector systems for present and future fusion research are in the range between 1011 and 1013 n/s and warrant biological shielding in most cases, even for low duty cycle operation. X radiation from the accelerator columns becomes a health physics concern only for injectors with energy higher than ∼100 keV.
