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.

The removal of aerosol particles and vapors in gas bubbles moving through a water pool is known to be an efficient means to reduce source term to the environment during severe accidents, as happened in Fukushima Daiichi. This trapping, called pool scrubbing, entails a complex phenomenology in which hydrodynamics, thermal hydraulics, and aerosol physics strongly affect each other and determine the net transfer of radioactivity coming out from the aqueous pond. More than 20 experimental programs have addressed this issue since the early 1980s, but few of them did it in a systematic and representative way. This paper thoroughly reviews the entire pool scrubbing database until 2016 and assesses the adequacy of the experimental setup, representativeness of boundary conditions, weaknesses in decontamination factor derivation, data uncertainties, and some other aspects to finally synthesize a reduced number of experiments that could be used as an experimental matrix for the validation of pool scrubbing models. More than 500 tests were reviewed and classified as Qualified for Validation, Useful for Understanding, or Not Useful; less than 15% of these experiments are considered in the proposed validation matrix due to different reasons. Major insights and remaining needs are also highlighted. This work was conducted under the framework of the Integration of Pool Scrubbing Research to Enhance Source-Term Calculations, or the IPRESCA project, led by Becker Technologies, in the framework of the Sustainable Nuclear Energy Technology Platform/Nuclear Generation II & III Alliance/Technical Area 2.
