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 absorption cross sections of gold and boron have been measured at long neutron wavelengths with a single crystal spectrometer. Mica along with microcrystalline filters of Be and BeO was used as a monochromator for the wavelength range from 4 to 8.75 Å, and for longer wavelengths a mechanical monochromator was used to remove second and higher order neutrons. Neutron beams with negligible higher order contamination were obtained with a wavelength resolution Δλ/λ of 0.018. The total cross section of gold for wavelengths from 5 to 11.5 Å is σt = (54.56 ± 0.09) λ (0.46 ± 0.67) barns. Evaluation of the thermal neutron (2200 m/sec) absorption cross sections gave (98.8 ± 0.3) barns for gold and (7.56 ± 6) barns for boron in glass plates for use as secondary standards.
