The scheme uses the aneutronic P–11B reaction in an asymmetric centrifugal trap, differing markedly from conventional thermonuclear fusion. The authors propose a device that could serve as the foundation for a direct‑conversion nuclear electric power station. The device converts the kinetic energy of alpha particles directly to electricity without a thermal cycle, while heating and recuperating proton and boron ion energy in the plasma, where fast protons have an almost monoenergetic spectrum. These features enable resonance fusion to be realized.
A physical design of a device that can be a base for a direct-conversion nuclear electric power station is considered. The project considers the aneutronic reaction P–11B in the asymmetric centrifugal trap. Kinetic energy of nuclear particles (alpha particles) is converted into electrical energy inside this device; no thermal cycle is used. Heating and recuperation of energy of protons and boron ions take place in the plasma space. The presented scheme differs significantly from the conventional thermonuclear fusion. 'Fast' protons, which are the main energy component of plasma, have an almost monoenergetic spectrum. This makes it possible to realize the 'resonance' fusion.
