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.

Neutron total cross sections of natural chromium were measured from 1.0 to 4.5 MeV with intermediate energy resolution at intervals of 50 keV Elastic and inelastic differential scattering cross sections were determined over the energy and angular range of 1.5 to 4.0 MeV and 20 to 160 deg, respectively. Scattered neutron groups were observed corresponding to average inelastic excitation energies of 1.433 ± 0.009, 2.377 ± 0.008, 2.665 ± 0.005, 2.778 ± 0.007, and 2.970 ± 0.006 MeV. The experimental results were examined in terms of the spherical optical statistical model with additional consideration of the vibrational direct excitation of the 1.433 first-excited level
