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.

“Crud” is a problem in the solvent extraction process for nuclear fuel reprocessing. Crud is an emulsion stabilized by dispersed fine solids. Insoluble residues and precipitates play an important role in crud formation. The effect of insoluble residues on crud formation is studied using submicron particles of palladium, which is one of the elements contained in insoluble residues. Experiments are conducted on factors such as palladium concentration, particle size, and acidity. The experimental results indicate that the smallest palladium concentration in the aqueous phase that can stabilize an emulsion is ∼5 g/ℓ and that such an emulsion is of the oil-in-water type. Moreover, the palladium layer on globules is discussed, and a numerical estimation is performed to predict the time when stable emulsions start to form in a mixer-settler.
