[0033] According to a first embodiment of the invention, the inlet connection is arranged in the middle (height) part of the SG (3).

[0034] After entering the middle part of the SG (3), the hot liquid metal coolant is separated into two parts: the upflow, which cleans the upper part of the SG (3) and flows freely through the formed openings into an upper horizontal cold collector (10) with an underfilled coolant level, said upper horizontal cold collector being disposed in the annular space below the reactor head, between the SG and the casing of the pump; and descending flow, which washes the lower part of the SG (3), enters the lower accumulating collector (11), and flows from said lower accumulating collector (11) as an ascending flow through an annular channel extending along the reactor shell and through The passage formed by the in-housing radiation protection elements arranged between the separating casing, the casing and the casing of the SG and the pump, enters the ...

Abstract

The present nuclear reactor with a liquid metal coolant comprises a housing (1) having a separating shell (6) disposed therein. In the annular space (5) between the housing and the separating shell are disposed at least one steam generator (3) and at least one pump (4). Inside the separating shell (6) there is an active region (2), above which a heat collector (8) is disposed which is in communication with the vertically central portion of the steam generator (3) in order to separate a stream of liquid metal coolant into ascending and descending flows, or the heat collector (8) is in communication with the upper portion of the steam generator in order to create a counter-flow heat exchange regime. Below the reactor head is an upper horizontal cold collector (10) with an unfilled level of coolant, and below the steam generator (3) is a lower accumulating collector (11) in communication with the upper cold collector (10). The inlet of the pump (4) is connected to the upper cold collector (10), and the outlet of the pump (4) is connected to a lower annular pressure collector (12), wherein collectors (11) and (12) are separated by a horizontal partition (13), and collector (12) is in communication with a distributing collector (15) of the active region.

Description

technical field [0001] The present invention relates to nuclear energy engineering and, in particular, to the design of pooled fast neutron nuclear reactors with heavy liquid metal coolants (eg, lead, lead-bismuth eutectic). Background technique [0002] Known nuclear power plants consist of a reactor with liquid metal, where, below the underfill level are: the core, the steam generator, the main circulation pump with axial impellers and the shielding gas system, the impeller blades of which are mounted on sleeve, the axis of which is perpendicular to the axis of the pump, and the vanes can be turned to a position where the coolant flow is completely stopped in the pump (RU 15955U1, 2012). [0003] A detachable design of the core of a nuclear reactor is known, preferably using a liquid metal coolant as the coolant of the primary circuit. This structure includes a fuel assembly, a control and safety system (CSS) casing with absorbent, wherein the casing is secured to the bas...
