FIELD: heat-energy generation industry and power engineering. SUBSTANCE: method includes production of metal hydride and excess heat due to interaction between atoms of hydrogen isotopes and those of metal crystal lattice and removal of heat generated through heat sinks and heat-conducting liquid. Metal is chosen out of groups III, IV, and VII of elements having minimal effective section of thermal neutron absorption. Powdered material of metal hydride is mixed up with radioactive material. Mixture obtained is placed in cylindrical and annular metal boxes easily inserted one into other. Mixture is sintered to form solid state composite. Excess heat energy is produced in composite while displacing cylindrical box over longitudinal axis of annular box and its locking at desired displacement height. In this way heat energy is generated due to two simultaneously developing interrelated processes of induced fission of heavy nuclei in composite and fusion reaction of accelerated hydrogen-isotope nuclei in metal hydride. Device implementing this method has material of beryllium metal element, source of isotopes of deuterium and tritium atoms, solid state hydrogen isotope material granulated with metal, container for source of hydrogen isotope atoms, and heat consuming device. EFFECT: facilitated process of heat generation. 28 cl, 8 dwg
