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.

Practical aspects of accelerator-based monoenergetic neutron sources are reviewed. In particular, the reactions 3H(p,n)3He, 1Li(p,n)7Be, 11B(p,n)11C, 2H(d,n)3He, 2H(t,n)4He, 3H(d,n)4He, 1H(t,n)3He, 1H(7Li,n)7Be, 1H(11B,n)11C, 1H(l3C,n)I3N, and 1H(15N,n)15O are considered. The outstanding properties of the newly developed sources of kinematically collimated neutrons are stressed. Intense monoenergetic sources are discussed, and it is shown that by using 1H(t,n)3He, it should be possible to build a source of 14-MeV neutrons with an effective source strength of 1015 n/s that would also be useful in neutron radiotherapy.
