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.

This paper evaluates detritiation of air contaminated with tritium in the form of water vapor using a scrubber column filled with structured packing. This technique is based on isotopic exchange between tritiated water vapor and liquid water. In combination with a catalytic oxidizer operated at room or slightly elevated temperature, the scrubber column can also decontaminate air contaminated with tritiated molecular hydrogen. Mass transfer rates measured for structured packings made of stainless steel and copper alloy confirmed high efficiency of the detritiation process. Study of the effect of various operation parameters on column efficiency allows optimization of column operation. It was demonstrated that this technique is competitive with the drying technique with respect to the decontamination factor (DF) provided and the amount of tritiated water to be generated. Benefits offered by the wet scrubber technology are based on the nature of the isotopic exchange process. No need for regeneration allows reduction in the number of units and as such decreases the capital cost of the facility for continuous operation. The DF can be controlled by changing the flow rate of feedwater.
