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.

The calculation of the resonance escape probability in a lattice by means of a diffusion theory model requires a knowledge of the logarithmic energy width, ln E1/E2, of the resonance absorption region. This quantity is evaluated by fitting the results of a diffusion theory analysis which is averaged over neutron energy to an experimental value of the effective resonance integral. The result is In E1/E2 ≃ 2.6, which is much less than the value 5.6 which is ordinarily used in these calculations.
