Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of nuclear power engineering, in particular to a containment high-energy penetration and a concrete containment. BACKGROUND

[0002] The structure of the concrete containment is a 1.3-meter-thick steel-lined reinforced concrete structure, and the penetration serves as a passage for the medium pipeline to enter and exit the containment. First, a sleeve is embedded in the containment, and the medium pipeline penetrates the opening formed by the sleeve to enter and exit the containment. Meanwhile, the penetration head connects the embedded sleeve and the medium pipeline to achieve sealing. As the third safety barrier of the nuclear power plant, the containment must maintain its sealing and integrity under various operating conditions.

[0003] Mechanical penetrations are generally divided into low-energy penetrations and high-energy penetrations according to the fluid medium. The penetration is welded to the sleeve embedded in the containment at the inner containment connection through a fixed head, serving as the fixed point of the pipeline unit. In high-energy penetrations, the medium pipeline needs to be assumed to be broken at the fixed end point, which is located at the weld between the penetration head and the pipeline connection. Due to the high temperature and pressure of the high-energy pipeline medium, the pipeline design in the penetration area is difficult. According to technical requirements such as ANSI 58.2 and SRPBTP3-4, factors such as the need to assume a break at the fixed end point of the pipeline result in excessive load being transmitted to the containment sleeve. The sleeve is usually designed with a thick wall, making pre-fabrication, welding, and in-service inspection difficult. In addition, the water force load caused by the break will cause excessive acceleration of the valve in the penetration area. In order to facilitate the calculation of the pipeline unit in this area, measures such as bending and adding additional support need to be considered in the pipeline design. SUMMARY

DETAILED DESCRIPTION

[0022] Other advantages and effects of the present application can be easily understood by those skilled in the art from the description of the embodiments of the present application. The present application can also be implemented or applied in other different embodiments, and the details in the description can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the embodiments and features in the embodiments below can be combined with each other without conflict.

[0023] It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the drawings, not the number, shape and size of the components when actually implemented. The actual implementation of each component may be a random change, and the component layout pattern may be more complex.

[0024] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application, however, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details, and in other embodiments, the known structures and devices are shown in the form of block diagrams rather than in the form of details, to avoid making the embodiments of the present application difficult to understand.

[0025] Please refer to Figure 1 The present application provides a containment high-energy penetration, comprising: an inner pipe 1; a head assembly 2, the head assembly 2 is arranged on the inner pipe 1; a protective sleeve 3, the protective sleeve 3 is sleeved on the outer side of the inner pipe 1, and the head assembly 2 is blocked in the middle of the protective sleeve 3; an inner sleeve 4 and an outer sleeve 5, the inner sleeve 4 and the outer sleeve 5 are respectively sleeved on the outer side of the protective sleeve 3, one end of the inner pipe 1 and the corresponding one end of the protective sleeve 3 extend to the end of the inner sleeve 4 away from the head assembly 2, and the other end of the inner pipe 1 and the corresponding other end of the protective sleeve 3 extend to the outer sleeve 5; wherein the protective sleeve 3 is connected with the inner sleeve 4, the head assembly 2 is flexibly connected with the inner sleeve 4, and the outer sleeve 5 is flexibly and sealingly connected with the protective sleeve 3 on one side of the head assembly 2.

[0026] It can be found from the above that, in the structural design of the containment high-energy penetration, the flexible connection between the sleeves 4 in the head assembly 2 can reduce the stress ratio at this position according to the technical requirements of ANSI 58.2 and SRP BTP3-4, so that the pipe and containment sleeve design in the penetration area can be simplified without assuming a break. Specifically, the protective sleeve 3 is sleeved outside the inner pipe 1, so that the protective sleeve 1 can play a protective role when the weld is broken after being welded at the head assembly 2. The flexible connection between the protective sleeve 3 and the inner sleeve 4 can ensure that the displacement is within the allowable range of the flexible sealing material, and the sealing can be further ensured by this design. Moreover, the same flexible connection design between the outer sleeve 5 and the protective sleeve 3 can effectively absorb the displacement difference between the inner and outer shells. Therefore, the penetration structure design of the present application can optimize the head fixing point to a flexible connection to simplify the break assumption in the penetration area and optimize the pipe and containment sleeve design.

[0027] As shown in Figure 1 The head assembly 2 includes a head 21, a plurality of first flexible members 22, and a plurality of first transition sleeves 23. The first flexible members 22 and the first transition sleeves 23 are connected to each other to form a flexible connection component 230. One end of the flexible connection component 230 is connected to the inner sleeve 4, and the other end of the flexible connection component 230 is connected to the head 21.

[0028] In an embodiment of the present application, when the head assembly 2 blocks the passage between the inner pipe 1 and the protective pipe 3, the head 21 is installed on the protective pipe 3 by welding or other methods. Moreover, the head 21 is connected to the inner sleeve 4 through the flexible connection component 230 composed of the first flexible members 22 and the first transition sleeves 23, so as to optimize the head fixing point to a flexible connection, simplify the break assumption in the penetration area, and optimize the pipe and containment sleeve design.

[0029] In this embodiment, the flexible section is formed by the first flexible members 22 and the first transition sleeves 23, that is, the flexible connection component 230, to realize the flexible connection with the inner sleeve 4. Of course, the flexible section can also be formed on the head assembly 2, which is not described here.

[0030] Further, the head 21 includes a first head 211 arranged on the inner pipe 1, and a second head 212. One side of the second head 212 is connected to the protective sleeve 3 and the flexible connection component 230, respectively, and the other side of the second head 212 is connected to the first head 211, so as to seal between the protective sleeve 3 and the first head 211, and between the flexible connection component 230 and the first head 211.

[0031] In one embodiment of the present invention, the head 21 is structurally designed to include a first head 211 and a second head 212. The first head 211 serves as a through-hole head, sealing the passage between the inner pipe 1 and the protective pipe 3. The second head 212 is positioned between the first head 211 and the end of the protective pipe 3 to seal the protective pipe 3 and the first head 211. The upper end of the second head 212 is also flexibly connected to the flexible connection component 230 to optimize the head fixing point.

[0032] like Figure 2 As shown, the first head 211 is in the shape of an "I", the second head 212 is in the shape of a "D", the first joint 2121 at the lower end of the second head 212 is against the end surface of the protective sleeve 3, the second joint 2122 at the lower end of the second head 212 is against the joint 2111 on one side of the top of the first head 211, and the joint 2112 on the other side of the top of the first head 211 is against the end surface of the protective sleeve 3 close to the side of the outer sleeve 5.

[0033] In one embodiment of the present invention, during the specific installation process of the second head 212 and the first head 211, the top side joint 2111 at one end of the "I" shape in the "I" shape of the first head 211 and the second joint 2122 at one end of the "I" shape in the "D" shape of the second head 212 are connected by welding or the like. The top other side joint 2112 at the other end of the "I" shape in the "I" shape of the first head 211 is set against the end surface of the protective sleeve 3 near the side of the outer sleeve 5 and is fixed by welding or the like. The first joint 2121 at the other end of the "I" shape in the "D" shape of the second head 212 is set against the end surface of the protective sleeve 3 and is connected to the end surface of the protective sleeve 3 by welding or the like. The upper end of the "D" shape of the second head 212 is connected to the flexible connecting component 230.

[0034] like Figure 1As shown, the first flexible member 22 is a bellows expansion joint; wherein two ends of one bellows expansion joint are connected with two first transition sleeves 23 respectively, and two ends of one first transition sleeve 23 are connected with two bellows expansion joints respectively to form the flexible connecting component 230. In this embodiment, the first flexible member 22 can be a bellows expansion joint. Of course, it can also be other flexible structural members. In the specific installation process, one end of the bellows expansion joint at the outermost part can be welded with the end of the inner sleeve 4, and the other end can be welded with one end of the first transition sleeve 23. The other end of the first transition sleeve 23 can be welded with one bellows expansion joint again, and continue to connect multiple first transition sleeves 23 and bellows expansion joints, or be directly welded to the second head 212. Thus, the sealing between the protective sleeve 3 and the inner sleeve 4 can be realized, and the flexible connection between the second head 212 and the inner sleeve 4 can also be realized.

[0035] Specifically, the protective sleeve 3 includes a first protective sleeve 31 and a second protective sleeve 32, and the first protective sleeve 31 and the second protective sleeve 32 are respectively arranged on the two sides of the head assembly 2. The first protective sleeve 31 is arranged on the inner side of the inner sleeve 4, and the second protective sleeve 32 is arranged on the inner side of the outer sleeve 5.

[0036] In an embodiment of the present application, the protective sleeve 3 can be a segmented structure, that is, it includes two segments: the first protective sleeve 31 and the second protective sleeve 32. The first protective sleeve 31 is located on the inner side of the inner sleeve 4, and the second protective sleeve 32 is arranged on the inner side of the outer sleeve 5. The corresponding ends of the first protective sleeve 31 and the second protective sleeve 32 are arranged and welded on the two sides of the head assembly 2. Specifically, the corresponding ends of the first protective sleeve 31 and the second protective sleeve 32 are arranged and welded on the top one side joint 2111 and the top other side joint 2112 on the two sides of the first head 211 respectively.

[0037] Further, the protective sleeve 3 further includes a liner 33, and the liner 33 is arranged on the outer side of the first protective sleeve 31. The first protective sleeve 31 is elastically and sealingly connected between the liner 33 and the inner sleeve 4.

[0038] In an embodiment of the present application, when the protective sleeve 3 is elastically and sealingly connected with the inner sleeve 4, the liner 33 is arranged between the outer side wall of the first protective sleeve 31 and the inner side wall of the inner sleeve 4, and is sealingly connected. Specifically, the liner 33 is a flexible sealing material. Because the displacement amount needs to be ensured within the allowable range of the flexible sealing material during design, the sealing property can be further ensured through this design.

[0039] Specifically, the liner 33 includes: a steel liner 331; and a flexible seal 332, which is respectively arranged between the inner wall of the steel liner 331 and the outer wall of the first protective sleeve 31, and between the outer wall of the steel liner 331 and the inner wall of the inner sleeve 4.

[0040] In one embodiment of the present invention, when the inner sidewall of the steel liner 331 is connected to the outer sidewall of the first protective sleeve 31, a flexible seal 332 can be used to seal and flexibly connect the steel liner 331 to the first protective sleeve 31. Similarly, the flexible seal 332 can also be used to seal and flexibly connect the steel liner 331 to the inner sleeve 4. The flexible seal 332 can be made of a flexible sealing material. The flexible strength of the flexible sealing material only needs to be designed to ensure that the displacement is within the allowable range of the flexible sealing material.

[0041] like Figure 1 and 2 As shown, the outer sleeve 5 includes: an outer sleeve body 51 and a second flexible member 52 , one end of the second flexible member 52 is connected to the outer sleeve body 51 , and the other end of the second flexible member 52 is connected to the outer side wall of the second protective sleeve 32 .

[0042] In one embodiment of the present invention, the outer sleeve 5 is mounted on the outer containment shell 7 through the outer sleeve body 51 when flexibly connected to the second protective sleeve 32. One end of the outer sleeve body 51 is connected to the second protective sleeve 32 through the second flexible member 52, ensuring that the mounting structure of the outer containment shell 7 is consistent with the mounting structure of the inner containment shell 6, thereby absorbing the position difference between the inner and outer shells.

[0043] Preferably, the second flexible member 52 includes: a plurality of bellows expansion joints and a plurality of second transition sleeves (not shown in the figure), the two ends of a bellows expansion joint are respectively connected to two second transition sleeves, and the two ends of a second transition sleeve are respectively connected to two bellows expansion joints.

[0044] In one embodiment of the present invention, the second flexible member 52 can adopt the same structural design as the first flexible member 22. The outer sleeve body 51 can be connected to the outer side wall of the second protective sleeve 32 by only using a bellows expansion joint. Of course, the outer sleeve body 51 can also be connected to the outer side wall of the second protective sleeve 32 by using multiple bellows expansion joints and multiple second transition sleeves. Specifically, by connecting the two ends of each bellows expansion joint to two second transition sleeves, and connecting the two ends of each second transition sleeve to two bellows expansion joints, it is possible to connect multiple bellows expansion joints and multiple second transition sleeves in sequence in this way, thereby forming a multi-section spliced ​​flexible structure to achieve the function of flexible sealing connection.

[0045] Specifically, one end of the second protective sleeve 32 away from the head assembly 2 is inserted into the outer sleeve body 51, and the outer side wall of the second protective sleeve 32 is provided with a sealing seat 321, and the second flexible piece 52 is sealingly connected to the sealing seat 321.

[0046] In an embodiment of the present application, when the second protective sleeve 32 is sealingly and flexibly connected to the outer sleeve 5 through the second flexible piece 52, the sealing seat 321 is arranged on the outer side wall of the second protective sleeve 32 as a mounting point, so that the second flexible piece 52 is welded to the sealing seat 321, thereby ensuring the sealing of the connection between the second protective sleeve 32.

[0047] As shown in Figure 1 The present application also provides a concrete containment vessel, which comprises the foregoing high-energy penetration safety shell, and further comprises an inner containment vessel 6 and an outer containment vessel 7, wherein the outer containment vessel 7 is sleeved on the outer side of the inner containment vessel 6, the inner sleeve 4 is correspondingly installed on the inner containment vessel 6, and the outer sleeve 5 is correspondingly installed on the outer containment vessel 7.

[0048] In an embodiment of the present application, in the process of using the high-energy penetration safety shell to form a concrete containment vessel, the concrete containment vessel further comprises an inner containment vessel 6 and an outer containment vessel 7. The radial dimension of the inner containment vessel 6 is smaller than that of the outer containment vessel 7, so that the inner containment vessel 6 is sleeved on the inner side of the outer containment vessel 7, and the high-energy penetration safety shell passes through the inner containment vessel 6 and the outer containment vessel 7 in sequence. Specifically, the inner sleeve 4 of the high-energy penetration safety shell is correspondingly installed on the inner containment vessel 6, and the outer sleeve 5 is correspondingly installed on the outer containment vessel 7.

[0049] In summary, the protective sleeve 3 can play a protective role when the weld of the high-energy penetrating member head breaks by using the flexible sealing design between the head assembly 2 and the inner sleeve 4. Moreover, the first head 211 fixing point function in the head assembly 2 is optimized to a flexible design structure, and the stress ratio at this position can be reduced by subsequent pipeline design according to the technical requirements of ANSI 58.2 and SRPBTP3-4, so that the penetration area of the pipeline and the containment sleeve design is simplified without assuming a break. Specifically, at one end of the second head 212 on the welding side of the first head 211, the first flexible member 22 is connected with the inner sleeve 4, which can play a sealing and flexible connection role for the inner containment 5. The liner 33 sealed between the first protective sleeve 31 and the inner sleeve 4 by using flexible sealing material ensures that the displacement amount is within the allowable range of the flexible sealing material, which can further ensure the sealing and flexible connection between the protective sleeve 31 and the inner sleeve 4. In the structural design of the outer containment 7, the second flexible member 52 is used to flexibly and sealingly connect with the second protective sleeve 32, so that the installation structure of the outer containment 7 is consistent with the installation structure of the inner containment 6, which can effectively absorb the displacement difference between the inner containment 6 and the outer containment 7. Therefore, the present application effectively overcomes the shortcomings of the prior art and has high industrial utilization value.

[0050] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical idea disclosed by the present application should be covered by the claims of the present application.
