Can nuclear power plants be built more like products, and less like one-off megaprojects?

In this episode of Stranded, Marie Espitalier-Noël speaks with Kirsty Gogan, co-founder of TerraPraxis and managing partner at LucidCatalyst, about what it would take to make nuclear construction faster, more predictable and ultimately financeable. The conversation begins with a striking finding from the Nuclear Cost Drivers study: the enormous gap between successful nuclear programmes and recent high-cost Western projects cannot be explained by reactor technology alone. Design completion, experienced delivery organisations, construction sequencing and repetition matter just as much.

Marie and Kirsty explore whether small modular reactors genuinely solve this problem, or simply place smaller reactors inside conventional megaprojects. They discuss what nuclear could learn from automotive platforms, aircraft manufacturing and shipyards, and how open architectures could allow industrial customers to buy standardised energy systems rather than commission bespoke plants.

The episode also examines the commercial models emerging around advanced nuclear: hyperscaler demand, X-energy, Aalo Atomics, Blue Energy’s shipyard manufacturing and gas-to-nuclear strategy, and TerraPraxis’ work to repower coal plants while reusing sites, grid connections and local infrastructure. Finally, they compare the US financing ecosystem with Europe’s fragmented approach, and ask what institutions such as the EIB and other development banks would need to do to make advanced nuclear investable at scale.
