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.

Based on the experimental data of the total, nonelastic-scattering, and elastic-scattering cross sections and the elastic-scattering angular distribution of 209Bi, a set of optimal neutron optical potential parameters is obtained, and all cross sections of the neutron-induced reaction, angular distribution, energy spectra, gamma-ray production cross sections, and gamma-ray production energy spectra, especially the double-differential cross section for neutron, proton, deuteron, triton, and alpha-particle emission, are calculated and analyzed for n + 209Bi at incident neutron energies <20 MeV. Theoretical calculated data are compared with existing experimental data and other evaluated data from ENDF/B6 and JENDL-3.
