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.

The fission cross-section ratio 240Pu:235U has been measured as a function of neutron energy from 5 to 300 keV using ionization fission chambers, the time-of-flight technique, and the threshold cross-section method at the Lawrence Livermore National Laboratory's 100-MeV electron linear accelerator. Distinct structure is observed in the cross-section ratio over this subthreshold energy range.
