FIELD: nuclear energy.
SUBSTANCE: invention relates to a nuclear reactor of integral type with a liquid metal coolant. The reactor includes a reactor vessel (9) closed by a cover (1) having a lower chamber (16) formed by a separating structure attached to the reactor cover (1), an active zone, at least one circulation pump (21) of the primary circuit with a shell (2) of the circulation pump attached to the cover (1), at least one heat exchanger installed in the shell (20) attached to the cover (1), and a plug (25). The separating structure is made in the form of an annular element (11) attached to the reactor vessel (9), in the guide shell of which the end shell (3) is inserted, connected to the reactor cover (1). Internals (8) are interconnected and attached to the peripheral part of the reactor cover (1), the lower end of the shell (20) of the heat exchanger is located above the annular element (11), and the lower end of the shell (2) of the circulation pump (21) passes through the hole in annular element (11) into the lower chamber (16).
EFFECT: increased safety and reliability of the reactor.
