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 prompt-neutron-induced fission spectra of 233U, 235U, 239Pu, and 240Pu were measured relative to the prompt-spontaneous-fission-neutron spectrum of 252Cf. Analysis of the measured values indicates that the incremental average-fission-neutron energies relative to a 252Cf fission-neutron spectrum of Maxwellian form with an average energy of 2.13 MeV are −123 ± 30 (233U), −157 ± 24 (235U), −76 ± 29 (239Pu), and −46 ± 29(240Pu) keV.
