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.

An experimental facility has been developed for short-half-life neutron activation studies. Sample material is transported between the irradiation position and the counting position by a constant-velocity cog belt. This facility has been used to measure the 53Cr(n,p)52V cross section relative to the 52Cr(n,p)52V cross section below 9.4 MeV, using elemental chromium metal as a sample material. The measured ratios and previously reported cross-section information for the 52Cr(n,p)52V have been used to derive values for the 53Cr(n,p)53V cross section. The 235U thermal-neutron fission spectrum average has been calculated from the differential results, and comparison is made with reported integral data.
