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.

Experimental data showing generation of 4He from a Pd sheet-D2 gas system observed by E. Botta et al. are analyzed by the trapped neutron catalyzed fusion (TNCF) model. The proposed mechanism of 4He generation is not the direct d-d reaction but the reactions between the trapped neutron and a Pd isotope, n-46APd reactions, with a supplemental assumption, decrease of threshold energies for (n,) reactions of 46APd in solids. The arbitrary parameter nn, the density of the trapped neutron, of the model is determined to be ~1012 cm-3, which is consistent with values determined in analyses of data in various events in the cold fusion phenomenon.
