SUBCRITICAL REACTOR (VARIANTS) Russian patent published in 2019 - IPC G21C1/30 

FIELD: nuclear engineering.

SUBSTANCE: invention relates to nuclear engineering, namely to the design of fast-neutron nuclear reactors operating in the subcritical mode, designed for decentralized power supply. Subcritical nuclear reactor consists of a core containing nuclear fuel in the form of nuclides with heavy nuclei and a source of fast neutrons with a kinetic energy on a large scale more than 1 MeV. Mass of nuclear fuel is less than the critical mass, which ensures the maintenance of a chain reaction in a fissile material. Initial nuclear fuel is natural uranium, containing predominantly ²³⁸₉₂U isotope, or natural thorium, containing predominantly ²³²₉₀Th isotope. Thickness of the layer of nuclear fuel in the direction of emission of neutrons from the source is at least 0.1 m, and the active zone is surrounded by a reflector.

EFFECT: providing power supply to areas with compact living of people with safe devices for generating electricity with minimal losses to transport it.
