Lava rock from deep-source volcanoes in Hawaii and Iceland provided physical evidence of a nuclear reactor at the earth's core. The lava contained tiny amounts of isotopes helium-3 and helium-4. Scientists had already known about the helium-3, but they thought it was left over from earth's formation. Herndon claims that no known physical process could produce helium-3 except for nuclear fission.

Furthermore, the proportion of the two helium isotopes matched the prediction of the Oak Ridge simulation and gave further evidence that a geo-reactor was at work in the core of the earth. Herndon and Hollenbach theorized that earth's ball of uranium has been operating as a nuclear reactor for about 4.5 billion years, with an output of 4 million megawatts. Much of the energy is heat which may power a mechanism that produces the geomagnetic field, Herndon told UPI.

The Oak Ridge programs also suggested earth's reactor produces more nuclear fuel than it consumes, which has enabled it to operate for billions of years. Also, the reactor's power level varies in intensity over time and shuts down periodically, because of the accumulation of fission products. A reactor produces lighter elements, such as strontium or barium, as the uranium fissions or splits apart.
