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 fission cross section of 243Am was measured in the neutron energy range from 1 eV to 10 MeV. Several methods of neutron production were employed using the Van de Graaff accelerator and the electron linear accelerator of the Central Bureau of Nuclear Measurements. The energy averaged fission cross section measured at the Geel electron linear accelerator (GELINA) above 100 eV and the fission cross sections measured at the Van de Graaff above 350 keV were determined relative to the 235U(n,f) cross section. The detailed neutron cross sections measured at GELINA in the 1-eV to 30-keV range were measured relative to the 6Li(n, t)4He cross-section shape and were normalized to the known fission integral of 235U between 7.8 and 11 eV. The present data provide unique new information between 1 and 50 eV. In this energy range, fission areas from 31 resonances were determined. In the subthreshold region above 100 eV, the present results demand drastic corrections of the evaluated data files by factors up to 6. Between the first and second chance fission threshold, the present experiment supports the ZEBRA integral experiment, which suggested a reduction of the fission cross section of 243Am in this region by 12% with respect to an earlier data set.
