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 60Ni were measured with broad resolutions from ∼0.5 to 5.0 MeV at intervals of ≲50 keV. Differential elastic neutron scattering cross sections were measured from 1.5 to 4.0 MeV at intervals of ≲50 keV over the scattered neutron angular range from ∼20 to 160 deg. Differential cross sections for the inelastic neutron excitation of states at 1.342 ± 0.013, 2.168 ± 0.010, 2.304 ± 0.026, 2.509 ± 0.022, 2.636 ± 0.019, and 3.164 ± 0.041 MeV were also measured. The experimental results are interpreted in terms of optical-statistical and coupled-channel models, including consideration of compound nucleus fluctuations and direct-vibrational processes.
