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.

Particle confinement time τp has been obtained from measurements of poloidal and toroidal distributions of Ha and Lyman a emissions in CHS. These particle confinement times range between 1.5 and 4ms at a constant line-averaged density of 3×1013cm–3 for both cases of limiter- and divertor-dominated NBI plasmas with Ti-gettering. In these cases the energy confinement time τE were between 2 and 3ms. The density decay characteristic time τp* and global recycling coefficient R have been also measured for Ti-gettered plasmas and large τp* values were observed. As a result high recycling rates (R>0.92) are obtained for a wide density range. For a limiter-dominated case of boronized plasmas (Rax=92.1cm) values of τp were correlated with τE and a linear correlation between them was found for normalized τE to P-0.58 which is a power degradation term in LHD empirical scaling.
