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.

Resonance parameters, particularly the radiative width of the 292.36-eV s-wave level in 91Zr + n, have been reinvestigated. The spin assignment J = 2+ is supported. The neutron width Γn = (866 ± 11) meV and radiative width Γγ = (86.8 ± 2.2) meV indicate less neutron capture than do parameters derived from earlier studies. This lower capture, however, is more compatible with integral measurements and a lead slowing down spectrometer measurement.
