FIELD: nuclear energy.
SUBSTANCE: invention relates to nuclear reactors with a liquid nuclear fuel circulation circuit, in which the fuel circulation circuit is not used for simultaneous heat removal. Cooling is performed by means of an additional heat carrier circuit, which is in direct thermal contact with a channel for the liquid fuel. This allows complete use-up of the advantages of liquid fuel at simultaneous optimization of the heat carrier circuit. Besides, using excess neutrons it is possible to deactivate radioactive components in spent fuel elements or to produce medical radioisotopes.
EFFECT: technical result is improved neutron economy of the reactor enabling deactivation of own long-lived decay products to make it necessary to store only radioactive wastes with a short half-life.
