Definitions
- the invention relates to nuclear energy and can be used for the manufacture of fuel elements (fuel elements) of power reactors.
- the operational reliability of the fuel rods is largely determined by the quality of the welded joints made.
- the argon-arc welding (ADF) method of non-consumable tungsten electrode is used.
- welded joint assembly comprising a shell and a plug, having the design of a butt-lock connection with a molten bead located on the plug (in the book "Design, Production and Operation of Fuel Elements of Power Reactors" edited by F.G. Reshetnikov book 2, Energoatomizdat, 1995, p. 185-186, table 20.1a).
- materials of the same class are used, including high-chromium steels of ferritic-martensitic class.
- the requirements for welded joints are determined by OST 95 503-2006.
- the main disadvantage in welding high-chromium steels of ferritic-martensitic class is their tendency to form quenching structures and cold cracks that occur after a certain time after the welding process.
- the technical result of the invention is to ensure the reliability of the sealing of the fuel elements of a nuclear reactor with shells of high-chromium steels, by obtaining high-quality welded joints of the shell with a plug without subsequent heat treatment of the weld, which simplifies the manufacturing process of its manufacture.
- the technical result is achieved in the weld joint of the shell of the fuel element with a plug made of high-chromium steel, connected by argon-arc welding, and it uses a shell of ferritic-martensitic steel and a plug of ferritic steel, with parameters selected from the ratios:
- a is the width of the bead flange
- the technical result is achieved in the weld joint of the shell of the fuel element with a plug made of high-chromium steel, connected by argon-arc welding, and it uses a bimetallic shell, the outer layer of which is made of ferritic, and the inner layer of ferritic-martensitic steel with a ratio of thicknesses 1: 1 or 1: 2, and a plug made of ferritic-martensitic steel, with parameters selected from the ratios:
- B ⁇ is the thickness of the outer layer of the bimetallic shell
- the technical result is achieved in the weld joint of the shell of the fuel element with a plug made of high-chromium steel, connected by argon-arc welding, and it uses a shell of ferritic-martensitic steel and a bimetallic plug, the outer layer of which is made of ferritic steel, and the inner layer of ferritic martensitic steel, with parameters selected from the ratios:
- ⁇ is the thickness of the outer layer of the bimetallic plug.
- the technical result is achieved in the weld assembly of the shell of the fuel element with a plug made of high-chromium steel, connected by argon-arc welding, moreover, it uses a shell and a plug made of ferritic-martensitic steel, and a ferrite steel ring is placed between them, with parameters selected from the ratios:
- a is the width of the bead flange; b - penetration depth;
- a sheath-plug connection scheme is used, made of high-chromium steel of ferritic and ferritic-martensitic class, changing their relative position in the assembly, thereby forming a ferritic phase in the weld metal, which makes it possible to exclude additional heat treatment of the weld after welding (in the book "Welding in mechanical engineering: a Handbook. In 4 volumes.” under the editorship of G.A. Nikolaev and others - M .: Engineering, 1978 - -v. 2 / Under the editorship of A.I. Akulov, p. 179-183).
- the process of manufacturing fuel elements of a nuclear reactor is simplified.
- FIG. 1 shows the design of the welded joint assembly, which includes a shell 1 of steel of ferritic-martensitic class and a plug 2 of steel of ferritic class.
- FIG. 2 shows the design of the welded joint assembly, which includes a bimetallic sheath 1, the outer layer 3 of which consists of ferritic steel, and the inner 4 of ferritic-martensitic steel, and the plug 2 of ferritic-martensitic steel.
- the node In order to obtain a ferritic phase weld in the metal according to this design option, the node must comply with the parameters selected from the relations:
- ⁇ is the thickness of the outer layer of the bimetallic shell
- Fig. 3 shows the construction of the weld joint assembly, which includes a shell 1 of steel of ferritic-martensitic class and a bimetallic plug 2, the outer layer 5 of which consists of steel of ferritic class, and the inner 6 of steel of ferritic-martensitic class.
- ⁇ is the thickness of the outer layer of the bimetallic plug.
- Figure 4 shows the design of the welded joint assembly, which includes a shell 1 and a plug 2 made of ferritic-martensitic steel, as well as a ring 7 made of ferritic steel, installed between the shell and the plug in the welded joint area.
- the node In order to obtain a ferritic phase weld in the metal according to this design option, the node must comply with the parameters selected from the relations:
- C is the thickness of the ring
- the width of the shoulder should be from 0.2 to 1 mm;
- the penetration depth is not less than the shell thickness, but should not exceed its thickness by 1, 2 times;
- Welding modes providing the required quality of a welded joint with a given phase composition of the weld metal according to the developed designs are:
- welding current 14-20 A welding speed 12 - 15 m / h;
- EP-823 ferritic-martensitic steel with a diameter of 9.3 mm and a wall thickness of 0.5 mm was used as the fuel cladding, and the plug was made of 05Kh18S2VFAYU ferritic steel, the flange width in the plug was 0.8 mm, its diameter corresponded to the shell diameter ( Figure 1).
- the fuel rod was sealed by the ADS method according to the regime:
- a 0.5 mm thick bimetal cladding was used as the fuel cladding, the outer layer of which is made of 05Kh18S2MVFAYu steel, and the inner one of EP-823 steel with a thickness ratio of 1: 2.
- the plug was made of EP-823 steel, its bead width was 0.8 mm ( Figure 2). Welding of the shell with a plug was carried out in the same mode as in example 1.
- EP-823 steel with a thickness of 0.5 and a bimetallic plug were used, the outer layer of which is made of 05X18C2MVFAY steel and the inner layer is of EP-823 steel (Fig.Z).
- the thickness of the outer layer of the plug made of steel 05X18S2MVFAY in the welding zone was 0.2 mm.
- the welding mode of the shell with the plug was the same as in example 1.
- Table 1 presents the mechanical properties of welded joints according to the developed options for the design of joints.
