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 streaming ray technique was developed as a method for solving two-dimensional stationary transport problems. A formulation for applying a similar approach to the solution of one-dimensional time-dependent problems is given. As in the stationary case, use is made of an SN-type grid and a second independent grid comprised of streaming rays. For time-dependent problems, the streaming ray grid enables accurate tracking of wave fronts, while the SN grid provides a mechanism for the calculation of the scattering source. Sample calculations are given, and the results are in excellent agreement with analytical benchmark solutions.
