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 process of neutron slowing down in a nonabsorbing medium is reviewed, and the distinction between average energy or lethargy after n collisions and the average number of collisions to reach a given energy is emphasized. Fermi's remark about neutron slowing down in hydrogen is explained and rederived.
