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.

The relationship between higher order variational principles for linear functionals of the solution to an inhomogeneous equation and Padé approximants for the same functional is shown. This leads to a deeper understanding of these higher order principles. Further, it is noted that in certain cases, the Roussopoulos functional can yield divergent results while using the Ritz procedure, shown to be equivalent to forming Padé approximants for the functional of interest, gives a generalized Schwinger normalization independent variational principle that can yield finite and convergent results.
