Title: Method and device for producing nuclear fusion of hydrogen isotopes
Inventor: GUY ARNAUD
IPC: G21B3/00
Filed: 1993-03-25
Abstract: The object of the device is to exploit the thermal energy released by a physical phenomenon, known by the name nuclear fission. The base nuclide is that of deuterium which, by fusion, delivers energy and gives rise to heavier nuclides. The apparatus consists of a hydridable sonotrode (1), for example made of titanium. At its bottom end, the sonotrode (1) is bored so as to constitute a chamber (2) which contains an electrode (3). The deuterium enters at (4), a heat-exchange and dielectric fluid circulates at (5). Nuclear fission takes place within the sonotrode (1) which is entered by the hydrogen isotope. It results in two combined effects, namely: 1e) Pressurisation and relaxation of the metal, caused by the propagation of ultrasound. 2e) Electromagnetic induction, due to the voltage applied between the electrode (3) and the sonotrode (1). The device is completed by a liquid/gas phase separator (6), the reaction gases escaping at (7) and the heat-exchange liquid at (8).
