FIELD: power industry.
SUBSTANCE: light-water reactor with supercritical heat carrier parameters and with a single-line/two-line heat carrier flow patterns includes a housing with cold heat carrier supply branch pipes and hot heat carrier removal branch pipes, pressure and discharge chambers, a supporting plate with risers, and fuel assemblies. A jet pump is arranged at the inlet of active zone in the supporting shell or the shank of the fuel assembly. The jet pump nozzle is connected to the pressure chamber of the reactor, and heat carrier injection channel (channels) is connected to the volume between fuel assemblies.
EFFECT: stability is ensured.
