FIELD: nuclear power plants (NPP).
SUBSTANCE: nuclear reactor comprises a core with vertically installed fuel assemblies in it, fastened with spacer grids, and vertical channels made around the circumference of the core configured for coolant flow through them and connected to the core by horizontal channels adapted for its supply. Moreover, each spacer grid adjacent to the vertical channels corresponds to at least one horizontal channel, each of which is installed in close proximity to the spacer grid above or below it. Some of the vertical channels are equipped with filter gratings in the upper or lower part.
EFFECT: increased safety of operation of a nuclear reactor by providing effective cooling of its core in emergency conditions.
