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.

A short ion bombardment greatly increases the hot saline etching or leaching of silicate glasses. The effect was observed for xenon, argon, neon, helium, and deuterium ion bombardment. From the relative values of the effect produced by the several ions, it was demonstrated that the effect is associated with the hot secondaries. The hot saline can cause the complete removal of material, thus producing a depression of an irradiated area, which was measured interferometrically, or it may cause a leaching of the cationic content of the glass and leave a silaceous residual film, which was studied by obtaining its spectral reflectivity. Other glasses may behave in an intermediate manner leading to some depression and some film residue. The glasses studied were soda-lime glass, light barium crown (28% BaO), and two facsimile radioactive waste storage glasses. The first two showed the enhanced etching, the first waste storage glass a tenacious film, and the second waste storage glass showed the intermediate behavior, some etching, and some film residue. The enhancement of the etching rate of the light barium crown glass was calculated as some fivefold, for the soda-lime glass about elevenfold. Enhancement of the leaching rate of the first waste storage glass was ∼2½ for helium ion bombardment and over 3½ for xenon or neon ion bombardment.
