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.

An equivalence principle is developed for an infinite array of annular rods. The center of a rod is a moderator characterized by the sticking probability γ1. Surrounding the center is an annular absorber characterized by the radii R1 < R2. The rods are uniformly distributed in an outer moderator characterized by the sticking probability γ2. The escape cross section for the lattice is The factor a is an adjustable Bell factor.
