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.

Calculations taking into account the influence of grain structure on the effective resonance integral of high-temperature reactor fuel assemblies caused by the use of coated particles are checked by measurements of such fuel assemblies with a lead spectrometer. The effect is quite remarkable and can be clearly seen from the measurements. Calculations show good agreement with our measurements.
