NUCLEAR REACTOR Russian patent published in 2016 - IPC G21C1/02 G21D1/00 

FIELD: energy.

SUBSTANCE: invention relates to nuclear power engineering, particularly to reactors of low and extremely low power. Nuclear reactor comprises a housing with a reflector. In the active zone there are first process channels intended for circulation of the heat carrier, and second process channels intended for arrangement of elements of control and protection system. Reactor also comprises chambers of the first loop heat carrier supply and discharge separated by a partition. First process channels are made as a Field tubing, external tubes of which are fixed at the bottom of the heat carrier supply chamber of the first loop, and internal tubes are fixed on the partition. Fuel assemblies are installed in the internal tubes of the Field tubing on suspensions mounted on the upper part of heat carrier discharge chamber of the first loop.

EFFECT: second process channels are isolated from the heat carrier supply and discharge chambers of the first loop, and annular space of the active zone is filled with a medium or a material transparent for neutrons.
