Abstract: A method of controlling a temperature of nonthermal nuclear fusion fuel, wherein materials of low boiling point are added as a coolant to a nonthermal nuclear fusion fuel mixed with liquid lithium (02), or nuclear fusion materials fused into liquid lithium (02), and rapid elevation in temperature of a local nonthermal fusion reaction region is suppressed by a heat vaporization of the materials of low boiling point so as to enhance the nonthermal nuclear fusion reaction. The materials of low boiling point are sodium or potassium.

Abstract: A method of and apparatus for generating recoilless nonthermal nuclear fusion reaction, wherein deuterium ions accelerated by pulsed gas discharge plasma are implanted onto a surface of an electrode (2) formed of liquid lithium (9), and the momentum to be transferred to the lithium atoms coming into collision with the deuterium atoms is carried out by neutrons, so that the lithium atoms are prevented from being recoiled, and the recoilless nonthermal nuclear fusion reaction is enhanced without reducing a cohesion acting between atoms in the liquid lithium (9).
