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.

This is a continuation of a previous article (1) wherein analysis of experimental data yielded a new procedure for the calculation of k∞/ϵ. In this present paper corresponding values derived from conventional theoretical techniques are analyzed in a similar fashion. The results as presented amplify the discrepancy between cadmium ratio measurements and conventional resonance escape theory, thereby yielding a good illustration of the need for further theoretical as well as experimental work in this area. A suggestion for improving the accuracy of cadmium ratio measurements is also presented. It is shown that the previous general development can be utilized with slight modification to yield values for the resonance escape probability which are in essential agreement with values calculated by conventional techniques.
