The deadline arrives: Checking in on the Reactor Pilot Program
On May 23, 2025, President Trump signed Executive Order 14301, “Reforming Nuclear Reactor Testing at the DOE,” which instructed the Department of Energy to create a Reactor Pilot Program (RPP)—a new system in which companies could pursue DOE authorization to build and test their first-of-a-kind nuclear technologies. EO 14301 set an ambitious goal for that program: three reactors achieving criticality by July 4, 2026.

This paper is a sequel to the previous work on the theory and application of the multilevel formalism to Doppler effect analysis. The first part of this paper gives some quantitative results in both the resolved and the unresolved resonance regions. Detailed discussions on the interpretation and analysis of these results are given. The second part of this paper describes some further studies on the statistical behavior of the S-matrix parameters with the emphasis on the residues. Both theoretical predictions and numerical results for cases pertinent to the reactor Doppler-effect analysis are given.
