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.

Confinement times of particle and trapped magnetic flux in FRC plasmas were simulated using a one dimensional transport model and classical (Spitzer's) resistivity. Comparing the simulation results and experimental results indicated that a transport in the plasmas was basically classical and deviations of experimental results from classical values (so-called anomaly) might attribute to a plasma geometry effect, by which the deviation was larger for fat plasmas and smaller for prolate ones.
In order to verify this indication, a plasma electron heating with an axial injection of pulsed and intense ion beams was proposed for the plasmas in current FRC experiments. Possibility of this heating were examined by estimating an energy deposit rate of a beam ion in the plasmas. The energy deposit rate is a few%~about 100% for a plasma of 12cm in diameter and 80cm in length with a plasma parameter range of current experiments.
