Definitions
- the invention relates to the electric power industry and can be used in horizontal steam generators of nuclear power plants (NPPs) with a pressurized water power reactor (WWER). BACKGROUND
- a steam generator is an essential element of the primary circuit of a reactor installation.
- the connection of the primary coolant collector with the bundle of heat exchange tubes is the most difficult to manufacture steam generator assembly.
- Particularly high requirements are imposed on this unit to ensure inter-circuit density. That is, the design of the connection node of the heat-transfer manifold should exclude the possibility of damage to heat transfer and other elements, the decompression of which leads to the ingress of radioactive water of the first circuit into the steam-water coolant of the second circuit, circulating through a turbine, condensers, heaters, etc. structural elements of a nuclear power plant reactor with the possibility of release of radioactive elements into the environment.
- the primary coolant collector used in horizontal steam generators is usually a thick-walled cylindrical vessel, the diameter and thickness of which vary along the length of the vessel. Through holes are made in the central cylindrical part of the collector, which serve to secure the ends of the heat exchange tubes in them.
- the lower cylindrical part of the collector is made with the possibility of welded connection with the nozzle of the steam generator body, and the upper cylindrical part of the collector has a connector (hatch) for access inside and is made with a tapered transition to the flange connection of the hatch with the cover.
- the main problems that may arise during the operation of the steam generator are related to the problems of ensuring the structural integrity of the flange connectors and the structural integrity of the primary coolant collectors.
- the most time-consuming and technologically complex operation in the manufacture of a steam generator is to connect a bundle of heat-exchange pipes with collectors of a primary coolant that requires drilling on a limited area of the side wall of the collector of many closely spaced deep through holes with subsequent hermetic sealing of heat-transfer pipes in them.
- the sealing gasket consists of two composite restrictive rings of the L-shaped profile and the sealing element between them made of pressed foil made of thermally expanded graphite located between them.
- thermally expanded graphite gaskets in the seal assemblies of the reactor installation reduces the likelihood of leakage of the primary coolant of the reactor installation when they are used to seal both cylindrical and end surfaces of the seal assembly.
- the technology for processing deep through holes in the collectors of steam generators, tube boards and other parts of the equipment of nuclear plants and petrochemical plants is described in RF patent N ° 2514359, published on 04/27/2014, IPC V23V35 / 00.
- the method includes pre-drilling a hole with a drilling tool consisting of a head and a stem. At the same time carry out the supply of cutting fluid (coolant) under a pressure of at least 4 MPa into the gap between the surface being machined and the drilling tool and the removal of chips by the coolant flow through the internal channels of the head and stem.
- Finishing is carried out by a reamer, which is installed on the same stem, and the removal of chips occurs through a drilled hole forward in the direction of movement of the reamer feed.
- the output of the sweep from the hole is combined with the smoothing of the surface of the hole, while the sweep is rotated with a number of revolutions that is up to 4 times higher than the revolutions during deployment, and the speed of the output of the sweep is 5% -7% higher than the working feed.
- the ends of the pipes are distributed on the inner surface of the collector, the pipes are welded, the hydraulic distribution is within the thickness of the collector, the front end is distributed in the zone adjacent to the inner surface, and the mechanical expansion is in the zone adjacent to the outer surface of the collector.
- the distribution of the front end of the pipes is carried out by mechanical rolling with 3 roller mills with restriction of torque on the drive shaft. After that, hydraulic distribution is performed in one or two transitions.
- the difference in diameters between the zones of mechanical rolling and the section where hydraulic distribution is carried out can withstand no more than 0.75 ⁇ -1% of the outer diameter of the heat transfer pipe.
- the described method is very time-consuming, relates only to one operation of securing the heat exchange pipes in the collector, does not cover the entire manufacturing and assembly technology of the primary coolant collector for the horizontal steam generator of WER nuclear power plants.
- the closest analogue of the proposed technical solution is a utility model protected by patent RU30928, published July 10, 2003, IPC: F22B1 / 02.
- the utility model relates to the manufacturing technology of a steam generator containing a housing and a heat exchange unit, including input and output collectors of a primary coolant with a beam connected to them horizontal heat transfer pipes.
- the horizontal heat transfer pipes are installed with a relative horizontal and vertical pitch equal to (l, 44-l, 55) d and (l, 35-l, 40) d, where d is the diameter of the pipe.
- the indicated range of steps for installing heat exchanger tubes covers, among other things, dense pipe bundles of the heat exchange bundle, however, the issue of placing the heat transfer tubes in the heat carrier manifold in the case of using the specified dense bundle of the heat transfer bundle remained unresolved. That is, in the case of using a tight arrangement of heat transfer pipes with a step of 1.44-d horizontally and 1.35-d vertically in accordance with this utility model, the strength conditions of the perforated part of the heat-transfer collector and the manufacturability of the heat-transfer pipes into the collector are not guaranteed when forming heat transfer bundle packets.
- the objective of the claimed invention is the creation of a horizontal steam generator assembly, including a primary coolant collector with a bundle of U-shaped heat transfer pipes, while ensuring the conditions of maintaining collector strength, tightness and adaptability of fastening in the collector of heat transfer pipes while increasing the filling of the steam generator with heat transfer pipes.
- the technical result of the invention is to ensure the strength of the jumpers of the collector wall between the holes for fixing the heat exchange pipes and the tightness of the connection of the heat exchange pipes with the collector, while the outer surface of the perforated part of the collector is most effectively used to insert pipes into it.
- a collector of the primary coolant circuit of a steam generator with U-shaped pipes of a horizontal heat-exchange beam made in the form of a welded thick-walled vessel having a perforated middle cylindrical part made with the possibility of installing and fixing a beam of U-shaped heat-exchange pipes in it, which are formed in packages and separated by vertical annular corridors, the lower cylindrical part, made with the possibility of a welded connection to the pipe body pair generator, and an upper cylindrical portion with a conical transition to the flange connection with the hatch lid, characterized in that the outer diameter D KCm collector of the first circuit in the middle portion is selected from the relation:
- d is the outer diameter of the heat exchange tubes, mm;
- n 2 the number of pipes in the horizontal row of the smaller and larger package of heat transfer pipes, respectively, mm;
- the holes for securing the heat exchange tubes are placed on the middle cylindrical part of the collector in a checkerboard layout, and the distance between the edges of adjacent holes horizontally on the inner surface of the collector is at least 5.5 mm.
- the distance between the edges of the holes on the inner surface of the body of the collector coolant is not less than 5.5 mm makes it possible to weld the end of the heat exchanger pipe along the entire circumference with the collector wall, which ensures the tightness of their connection.
- Heat transfer pipes fixed in the holes on the side wall of the collector are made in the form of seamless seamless tubes of austenitic stainless steel.
- heat transfer tubes are formed into packages with vertical annular corridors 100-250 mm wide.
- the heat exchange bundle is filled evenly from the top to the bottom with the gaps between adjacent pipes vertically not exceeding the vertical pitch of the tubes in the bundle.
- Holes made in the middle cylindrical part of the collector body fill the area of its outer surface from top to bottom and form a drilling zone.
- the indicated drilling zone is bounded below by a broken line in the form of a symmetrical wedge.
- the wedge has a truncated peak with a horizontal section.
- the size of the horizontal section is at least 3 (d 0TB + 6) mm.
- the presence and size of the horizontal section is selected from the condition of ensuring the reliability of the steam generator by reducing the residual stresses in the collector.
- the formation of a drilling zone in the form of a pointed wedge could serve as a stress concentrator, i.e. contribute to the initiation of cracks in the collector housing, therefore the pointed configuration of the drilling zone in the design of the claimed collector is not applied.
- the flange connection of the hatch with the lid is equipped with a gasket made of expanded graphite, in particular, of thermally expanded graphite, made in the form of a ring of pressed graphite foil reinforced with stainless steel tape. Sealing the flange connector with thermally expanded graphite gaskets reduces the tightening forces at the flange connection and improves the stress state of the coolant collector.
- Another object of the claimed invention is a method of manufacturing a heat carrier collector of the primary circuit of a steam generator with U-shaped pipes of a horizontal heat-exchange bundle, including the preliminary production of two forgings of complex shape and U-shaped heat-exchange pipes, assembling and welding forgings, drilling through holes in the middle cylindrical part of the collector, assembling heat transfer beam from U-shaped heat transfer tubes, which are formed into packets and separated in the beam by vertical annular corridors a first circuit eplenie manifold openings of each heat exchanger tube of the roller by rolling and welding the inner side collector, characterized in that the outer diameter ⁇ ⁇ collector of the first circuit in the middle portion is selected from the relation:
- d is the outer diameter of the heat exchange tubes, mm;
- the holes for fixing the heat exchange pipes are placed on the middle cylindrical part of the collector in a checkerboard layout, and the distance between the edges of the neighboring holes horizontally on the inner surface of the collector is chosen at least 5.5 mm.
- the heat transfer pipes are fixed in the holes on the middle cylindrical part of the collector by ring welding of the end each pipe with the inner surface of the collector, after which hydraulic distribution of the heat exchange pipe with mechanical rolling at the outer surface of the collector is carried out along the thickness of the wall of the collector until the gap between the collector body and the heat exchange pipe embedded in it is completely eliminated.
- the heat exchange bundle is filled evenly from the bottom to the top with the gaps between adjacent pipes vertically not exceeding the vertical pipe pitch in the bundle, and when the primary coolant collector is installed in the steam generator housing, the height of its drilling zone does not go beyond the placement of the upper row of tubes of the heat exchange bundle in the steam generator .
- the bending radii of the heat-exchange pipes are not less than 60 mm, preferably not less than 100 mm.
- An increase in the bending radius allows the introduction of an electromagnetic probe into each heat exchanger tube for a eddy current control of the integrity of the connection quality pipe.
- the conditions for ensuring the strength indicators of the coolant collector additionally require that, when drilling holes in the middle cylindrical part of the collector, the area of the outer surface of the drilling zone exceeds the area of the holes by at least 20%.
- the claimed invention allows you to select the outer diameter of the coolant collector in the range in which the technical result is achieved.
- the lower value of the obtained range of the diameter of the collector still allows us to ensure the technological fastening of pipes in the collector in the part of the circular welding of the ends of the pipes to the collector from the inside of the collector body and to ensure its strength.
- the upper value of the range of the diameter of the collector allows us to ensure the manufacturability of the steam generator assembly, namely, it guarantees the possibility of introducing all the tubes of the heat exchange bundle into the holes of the collector of the coolant.

- the figure 8 shows the termination of the heat exchange pipe in the hole in the side wall of the collector.
- collector 1 of the coolant of the first circuit of the horizontal steam generator has a housing, which is a welded thick-walled vessel.
- deep holes 3 are made, shown in cross section in figures 2 and 3, which serve to secure the ends of the heat exchange tubes 4 in them, as shown in FIG. 4, 5 and 8.
- the lower cylindrical part 5 of the collector is made as shown in FIG. 7, with the possibility of a welded connection to the pipe 6 of the housing 7 of the steam generator, and the upper part 8 of the collector has a flange connector for access inside. It is made with a conical transition 9 to the flange connection of the hatch with the cover 10.
- the coolant collector 1 has a middle cylindrical part 2 perforated by a plurality of openings 3, configured to install and fix in the indicated openings 3 a bundle of U-shaped heat transfer tubes 4, which are formed into packets 1 1 and 12 and separated by vertical annular corridors 13. Holes 3 are placed on the middle cylindrical part 2 of the collector in a checkerboard layout. Holes 3 made in the middle cylindrical part 2 of the manifold body
- FIG. 1 fill the area of its outer surface from top to bottom.

- From the second forgings form the upper conical part 8 of the collector 1 with a flange.
- a two-layer anticorrosive cladding is applied to the inner surface of the collector body 18.
- a predetermined number of U-shaped heat transfer tubes is manufactured.
- d is the outer diameter of the heat exchange tubes, mm;
- the holes 3 for fixing the heat exchange pipes 4 are placed on the middle cylindrical part of the collector in a checkerboard layout, and the distance between the edges of the neighboring holes 3 horizontally on the inner surface of the collector is chosen at least 5.5 mm.

- the housing 7 of the steam generator is filled with boiler water to a certain level above the beam
- Feed water is supplied to the steam generator through the pipe 21 for supplying feed water and a device for supplying and distributing feed water. Leaking out of it, the feed water is mixed with boiler water and warmed up to saturation temperature. The heat transferred from the primary coolant is consumed for the evaporation of boiler water and the formation of steam in the annulus of the steam generator. The resulting steam rises and enters the separation part of the steam generator, which is made in the form of free volume, separation devices, or a combination thereof. Having passed the separation part of the steam generator, the steam has a project-normalized humidity. Then it is discharged from the steam generator through the steam exhaust devices in the form of nozzles 22 for steam removal and ceiling hole sheets installed in front of them. The steam generated by the steam generator is then used in the steam-power technological cycle of power generation.
- connection of the primary coolant collector with the bundle of U-shaped heat transfer tubes is the node that is primarily required to ensure the inter-circuit density, since any decompression of it leads to the ingress of radioactive water from the primary coolant into the second-circuit steam and water circulating through a turbine and other structural elements of the reactor installation of a nuclear power plant with the risk of release of radioactive elements into the environment.
- the claimed technical solution related to the design of the collector of the heat carrier of the steam generator with U-shaped pipes of the horizontal heat exchange beam and the method of its manufacture creates the technical result, which consists in ensuring the guaranteed strength of the jumpers of the wall of the collector between the holes for fixing the heat transfer pipes, the tightness of the connection of the heat exchange pipes to the collector that the outer surface of the perforated part of the collector is most effectively used to establish pipes in him.
