Atomic Show #314 – Economies of scale for micro, small, medium, large reactors – with James Krellenstein
James Krellenstein is a physicist, consultant and nuclear energy historian. He is currently employed as a senior advisor to Global Health Strategies. He started up their decarbonization practice with an emphasis on nuclear energy along with renewables. He was the lead author on GEH’s report on ways to reduce global dependence on Russia for necessary supplies of enriched uranium. He had the unusual and fortunate experience of growing up with a father who was a nuclear engineer turned nuclear financial specialist and a grandfather who ran a custom manufacturing machinery production facility. Both were the kind of professionals that enjoyed their work enough to “bring it home” for discussions around the dinner table and while engaging in bonding activities like fishing and camping. (I know what that is like from both sides of the parent/grandparent/child relationship.) James has become a bit of an “overnight sensation” in the world of pronuclear podcasting most notably with repeat appearances on Dr. Chris Keefer’s Decouple Podcast and Age of Miracles, hosted by Packy McCormick and Julia DeWahl. He has an encyclopedic knowledge of the US nuclear industry and a unique perspective on current and future actions needed to restore its prominence. I was motivated to invite him for a chat after listening to his thoughts on the relationship between reactor size and the cost of produced electricity. We talked about the need for a larger catalog of options that can meet the needs of a wider variety of customers, the advantages of larger sizes in producing bulk electricity in grids and markets that can accommodate the output, and the differences between seeing reactors as a product that might be manufactured or seeing them as a “stick-built” factory that produces a bulk commodity. Though our emphasis and perspectives are different, we hold similar points of view. Our conclusions for prioritization vary considerably. I think you will learn something from this show and hope that you will take the time to share your thoughts on the topics discussed. Though there are many who dismiss the importance of conversation and discussion compared to concrete action that gets things done, it’s hard to successfully complete the latter without responsible and involved people engaging in the former.
