Is there a nuclear reactor at the center of the Earth?
PO Box 80021, 3508 TA Utrecht, The Netherlands
M.Herndon, in a series of papers, has proposed that a nuclear reactor is
operating at the center of the Earth. Part of his hypothesis is based on
the idea that the composition of the Earth is not, as usually assumed,
essentially chondritic, but has a more reduced composition comparable to
enstatite chondrites. The small amount of uranium in the molten metal
will, probably in the form of a uranium sulfide, migrate to the center of
the core. Herndon also assumes that there is a need for an extra heat
source, as the total heat leaving the core is stated to be more than can
be accounted for by "classical" heat sources.
In this contribution we will review the different hypotheses by comparing
the formation and composition of the Earth as commonly assumed with
Herndon's model Earth, and seek to answer the question whether nuclear
georeactors at the Earth's center are plausible, or at least possible.
