Deep Fission to break ground this week
With about seven months left in the race to bring DOE-authorized test reactors on line by July 4, 2026, via the Reactor Pilot Program, Deep Fission has announced that it will break ground on its associated project on December 9 in Parsons, Kansas. It’s one of many companies in the program that has made significant headway in recent months.

The effect of reducing the aspect ratio on the confinement of deuterium-tritium fusion products, i.e., alpha particles, in tokamaks is discussed. It is shown that for low-aspect-ratio tokamak reactors, the alpha-particle heating efficiency can be similar to conventional tokamaks; at the same time, the alpha-particle confinement time can be much shorter than that of conventional tokamaks. Thus, one can facilitate alpha-particle ash removal while maintaining high alpha-particle heating efficiency by reducing the aspect ratio.
