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.

Analyses of property changes during reirradiations and anneals show that the technique of alternate reirradiations and anneals can be used consistently to remove radiation damage from graphite. Laboratory experiments, monitoring studies and reactor-height measurements all correlate favorably. It is shown that the recovery for a reirradiation and annealing cycle is independent of irradiation temperature between 30 C and 200 C and total damage over wide ranges. The reciprocal of the recovery per cycle is a linear function of the exposure between anneals with a slope that is determined by the anneal temperature.
