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.

Uranium-236 neutron absorption is measured as a function of neutron time of flight from 20 eV to 1 MeV. The neutron flux is monitored with a 6Li glass scintillator. Average cross sections from 3 keV to 1 MeV are derived. Estimated uncertainties are <5% below 600 keV and increase to 9.5% at 1 MeV. From 20-eV to 4.2-keV neutron energy, 293 resonance peaks are parameterized.
