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.

It is shown that the erosion of the first wall due to sputtering in a tandem mirror fusion reactor (TMR) is not a serious problem. An erosion rate in the 0.3 μm/yr to 0.3 mm/yr range for the Mirror Advanced Reactor Study parameters is estimated. The natural end loss in a TMR deposits most of the charged-particle power and fueling current on the end collectors, far from the first wall. Therefore, most of the heating and sputtering take place on massive structures in the end tanks and do not affect the design of the first wall and blanket. Furthermore, the cool halo plasma in a TMR protects the first wall by reducing both the energy and the flux of particles that recycle between the wall the plasma.
