PLANETARY AND PROTOSTELLAR NUCLEAR-FISSION - IMPLICATIONS FOR PLANETARY CHANGE, STELLAR IGNITION AND DARK-MATTER

The feasibility of thermal neutron fission and fast neutron fission in planetary and protostellar matter is calculated from nuclear reactor theory. Means for concentrating actinide elements and for separating a ctinide elements from reactor poisons are described. The implications of intermittent or interrupted planetary-scale nuclear fission breeder reactors are discussed in connection with observed changes in the gia nt outer planets and changes in the geomagnetic field. The concept tha t thermonuclear fusion reactions in stars are ignited by nuclear fissi on energy is disclosed. The suggestion is made that dark matter, infer red to exist in the Universe, might be accounted for, at least in part , by the presence of dark stars (not necessarily brown dwarfs) whose p rotostellar nuclear fission reactors failed to ignite thermonuclear fu sion reactions.
