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.

Corrosion and creep behavior of tubes fabricated of three German stainless steels have been studied in a 10 000-h test in a sodium loop at 873 and 973 K. The measured weight losses depend on the temperature and the oxygen content of the sodium. The results of metallographic examinations with respect to the formation of ferritic surface layers are in agreement with element concentration profiles obtained by analytical techniques. The stabilized stainless steels pick up carbon from the sodium even at 973 K although the carbon content of the liquid metal is in the range of 0.1 to 0.2 ppm. The measured carburization corresponds to the thermochemical data of both the steels and the liquid alkali metal. The creep rates of two of the steels are not influenced by the sodium, and the third material in the cold-worked condition shows an acceleration of the creep by a factor of 5. The different behavior cannot be explained by structural or chemical changes in the materials due to the action of sodium. Future examinations will clarify the different effects of sodium on the behavior of the slightly different materials.
