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.

Extensive calculations have been carried out for neutron production from the 3H(d,n)4He, 3H(p,n)3He, and 2H(d,n)3He reactions using hydrated titanium targets. Both thin and totally stopping targets have been considered for ion energies up to 5 MeV. By using the appropriate ion energy, production angle, and reaction, and allowing an energy spread of 10%, it is found that one can obtain neutron current densities of the same order of magnitude with energies from 0 to 22 MeV except for the gap between 8 and 12 MeV. Above 1 MeV variation of all pertinent neutron production characteristics with target loading ratio are found to be essentially the same regardless of reaction type, ion energy, or production angle. Total neutron yields are also calculated along with an example neutron-energy spectrum.
