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.

Differential neutron elastic-scattering cross sections of 197Au are measured from [approximately equal to]4.5 to 10.0 MeV at incident-neutron energy intervals of [approximately equal to]0.5 MeV. These results are combined with previous lower-energy work by the author and associates to form a neutron-scattering database extending from [approximately equal to]0.3 to 10.0 MeV. A few elastic-scattering distributions and total cross sections from the literature are added to it, and the composite is interpreted in terms of optical-statistical, dispersion, and coupled-channels models. The results are compared with models in the literature and with relevant portions of the ENDF/B-VI nuclear data file. A collective rotational model for the prediction of neutron interactions in this mass-energy region is suggested.
