Breaking ground on a new approach to construction
The drive to Kairos Power’s reactor demonstration site in Oak Ridge, Tenn., is not only scenic—it’s historic. Nearly 85 years ago, roughly 30,000 construction workers transformed orchards and farmland into a key Manhattan Project site. Depending on your route, you may pass by one of the three gatehouses that were once military checkpoints controlling access to Atomic Energy Commission production facilities.

Nuclear thermal-hydraulics has a leading role in nuclear safety and in the viability of the nuclear industry. Over the past few years, there have been numerous innovations that are enabling the design of new and advanced reactor systems while providing increased margins of safety. NURETH-20 will highlight emerging technical innovations enabled by thermal-hydraulic research including passively cooled SMRs, advanced non-LWRs, “microreactors” cooled by heat pipes, and the use of artificial intelligence in data analysis. The opening plenary will feature several top innovators in the nuclear industry and provide an opportunity for attendees to hear how thermal-hydraulics makes it all possible.
