Abstract
Reverse steam generator for a lead-cooled fast reactor. The reverse steam generator comprises a cylindrical body with a bundle of heat exchange tubes located inside, the ends of the heat exchange tubes being fixed in tube sheets with intermediate support grids; inlet and outlet spherical chambers for supplying liquid metal coolant; a lower branch pipe for inlet water; and an upper branch pipe for a steam outlet. The cylindrical body is arranged horizontally and is curved in a Z-shape with a difference in height. The bundle of heat exchange tubes is also made in a Z-shape, repeating the bend of the cylindrical body.
Claims3
A reverse steam generator for a lead-cooled fast reactor, the reverse steam generator comprising:
- a cylindrical body with a bundle of heat exchange tubes located inside the cylindrical body, wherein ends of the heat exchange tubes are fixed in tube sheets, wherein intermediate support grids support the heat exchange tubes;
- inlet and outlet spherical chambers for supplying liquid metal coolant;
- a lower branch pipe for inlet water;
- and
- an upper branch pipe for a steam outlet;
- wherein the cylindrical body is configured to be arranged horizontally and is curved in an offset-shape defined with (i) a first portion of the cylindrical body and a second portion of the cylindrical body having a height difference relative to one another and (ii) a third portion of the cylindrical body being inclined relative to the first portion of the cylindrical body and the second portion of the cylindrical body such that the third portion of the cylindrical body bridges the first portion of the cylindrical body and the second portion of the cylindrical body and the first portion of the cylindrical body and the second portion of the cylindrical body do not extend one over another and extend from the third portion away from each other in opposing horizontal directions, wherein the first portion has a water inlet oriented at a first direction along a first plane and the second portion has a vertical steam outlet oriented at a second direction perpendicular to the first direction along a second plane different from the first plane, and wherein the bundle of heat exchange tubes is also curved in an offset-shape that matches the offset-shape of the cylindrical body and aligns with the shape of the cylindrical body.
