Construction begins on Kairos’s fluoride salt–cooled test reactor
Earlier today, on a site in Oak Ridge, Tenn., that was formerly home to the K-33 Gaseous Diffusion Plant, Kairos Power marked the start of construction on its low-power demonstration reactor. Named Hermes, the 35-MWt test reactor claims status as the first Gen IV reactor to be approved for construction by the Nuclear Regulatory Commission and the first non–light water reactor to be permitted in the United States in more than 50 years.

During the past two years a team at Lawrence Livermore National Laboratory (LLNL) has used Raytheon's TopAct code to convert a variety of CAD models into TART and MCNP Monte Carlo input files. TopAct offers the possibility of enormous savings by largely eliminating the need for manual generation of models via combinatorial geometry. Also, TopAct is expected to deliver improvements in quality assurance and configuration management. We detail our experiences with various test problems. The reader will see the steady improvements that have been made in the conversion process and understand our expectations for further progress. Finally, we explain how TopAct will become a cornerstone of our future neutronics efforts.
