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 mass-yield distribution of fission products following degraded-fission-spectrum neutron-induced fission of 232Th was measured by gamma spectrometry for 25 mass chains including mass 138 for the first time for fast fission. Cumulative yields for 83gSe and 130gSb were observed, the latter also for the first time for fast fission. In general, the yields for degraded-fission-spectrum neutron-induced fission of 232Th were slightly higher in the inner portions of both the heavy and light mass wings than for those from reactor-neutron-induced fission of 232Th. This was expected, since the average energy of degraded-fission-spectrum neutrons is slightly above that of reactor neutrons.
