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.

For the supercritical CO2 Brayton cycle of a sodium-cooled fast reactor, we carried out surface reaction tests for sodium temperatures ranging from 200 to 600°C. Based on the test results, we found that the reaction kinetics over the sodium temperature range of 300 to 550°C depends heavily on the temperature but is not sensitive to the velocity of CO2 flowing over the gas-liquid reacting interface explored in this study. Gaseous and nongaseous reaction products were sampled and analyzed quantitatively. The rates of the chemical reaction were determined by measuring the gas concentration of the CO/CO2 mixture. Then, we proposed a two-zone reaction model with a threshold temperature of 460°C. The kinetic parameters for each reaction zone were experimentally obtained.
