The non-nuclear route to cheaper reactors

For decades, nuclear has struggled with cost overruns and delays — Georgia’s Vogtle plant being the latest example. Kairos Power co-founder and CEO Mike Laufer thinks the solution is to flip the script: focus first on non-nuclear demonstrations and then iterate quickly. It’s a counterintuitive and potentially risky strategy . Rapid iteration isn’t the way engineers or funders like the DOE have traditionally developed nuclear plants. Kairos also combined two technologies — TRISO fuel and molten salt — into a first-of-a-kind design. Theoretically it would be safer, but Kairos was also tackling one of the hardest problems in engineering: building a reactor from scratch. After eight years of development, its approach has led to three engineering test units, a novel contracting model with the Department of Energy, and a landmark partnership with TVA and Google to deliver nuclear power to data centers. So how did Kairos pull it off? In this episode, Lara talked with Mike about how Kairos executed its ambitious iterative approach without overextending itself. They also cover why Kairos chose to vertically integrate and build its own in-house machine shop, plus what technical setbacks taught the team. Credits: Hosted by Lara Pierpoint.
