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 age of fission neutrons to indium-resonance energy has been measured in AGOT graphite using the point-source technique. Corrections to the data arising from the following factors were investigated: (a) source and foil size, (b) finite dimensions of medium, (c) higher- and/or lower-energy activations, and (d) angular sensitivity of detector foils. The age was determined to be 307.8 ± 1.9 cm2; the fourth and sixth moments were 6.58 ± 0.05 × 106 cm4 and 3.84 ± 0.06 × 1010 cm6, respectively. These agree well with the values of 307.4 ± 1.0 cm2, 6.59 ± 0.06 × 106 cm4, and 4.01 ± 0.09 × 1010 cm6 obtained by Monte Carlo calculations.
