Fermi's nuclear reactor theory provides a simple yet powerful way to ascertain whether a mass of fissionable uranium will be able to sustain chain reactions and function as a nuclear reactor. Kuroda's 1956 work, and Herndon's 1992, 1993,1994, and1996 works were all based upon Fermi's nuclear reactor theory.

But Fermi's theory does not answer some of the important questions, such as the nature of fission products produced. Because of national security concerns, for more than thirty years, scientists and engineers at Oak Ridge National Laboratory have developed and tested computer programs to simulate numerically different types of nuclear reactors. These programs have been validated by comparing predicted results with analyzed spent nuclear fuel rods from nuclear reactors.

Georeactor research took a major step forward when Daniel Hollenbach showed me that those programs would be applicable to a deep-Earth nuclear reactor with just minor changes. The results of the first nuclear georeactor simulations published were published in 2001 in the Proceedings of the National Academy of Sciences USA (click here). The numerical simulations not only confirmed previous calculations, and showed that the georeactor could function over the lifetime of the Earth, but additionally provided the amounts of the various products of fission. The helium fission product results, which agree with what is found in deep-source lavas, such as Hawaii and Iceland, provide the first strong, direct evidence for a nuclear reactor at the center of the Earth.
