METHOD FOR CARRYING OUT A FISSION NUCLEAR CHAIN REACTION ON RESONANCE NEUTRONS

摘要

The present invention relates to the nuclear engineering and is designed to produce a nuclear fission chain reaction for obtaining large fluences of neutrons, gamma-ray quanta, and producing thermal and electric power. It is an object of the invention to reduce mass and improve the usage efficiency of nuclear fuel in the nuclear reactor core. The invention is essentially based on the fact that all of the fast neutrons can be slowed down, substantially without losses, to thermal energies at which they may be considered stationary when arriving at the vacuum magnetic trap as their velocity is low as compared to the velocity of the fissile material nuclei movement, and, therefore, all of them may react even at a relatively low density of the fissile material. The fissile material critical mass in the reactor core is considerably reduced (up to few grams or tens of grams). The invention ensures that great energies, (1000 megawatt and greater) can be released in the reactor core as the fission products containing more then 90 percent of the nuclear power released may be removed from the reactor core and directed to the facilities for direct conversion of their energy. e.g., into electricity. The nuclear reactor is substantially safe from the environmental standpoint as at any given time the amount of the fissile material in the reactor core will not exceed few tens of grams.
