    [0001] The present invention relates to the field of technology of control rod drive mechanisms in the PWR nuclear power plant (PWR), and concerns in particular, a strong alloy nickel-based enclosure and its method of implementation.
    [0002] The PWR control rod drive mechanism is mounted on the top cover of the reactor pressure vessel, which can cause the control rod components to perform upward and downward movements in the core according to the instructions, and maintain the height indicated in the control bar instructions, also release the control components by turning off to quickly release into the heart under the effect of gravity in order to finish the start, power control, power maintenance , normal shutdown, accidental shutdown of the reactor, etc.
    [0003] Currently, L-106A-type control rod drives and its derived types (hereafter referred to as Type A) are available in the majority of the second generation of international PWRs put into operation in the second generation (including modified second generation), while L-106B-type control rod drives and its derived types (hereinafter referred to as B-types) are available in most third-generation PWRs under construction in the third generation. The drive mechanisms of the control rods 6 of types A and B are fixed on the reactor top in the following manner: inserting the metal penetration part 5 into the pressure vessel lid 7 of the reactor and then welding to form a together with the lid of the pressurized container 7 of the reactor. Figure 1 shows the position 3032058 2 of the driving mechanism of the control rods 6 in the reactor. The enclosure of the control rod drive mechanism 6 is part of the pressurized boundary of the reactor primary circuit, acts as a support for the drive mechanism and the load role in service at the same time. Thus, the pressurized boundary of the drive bar drive mechanism is generally referred to as the heavy duty enclosure which generally includes the enclosure component and the travel sleeve component of the drive shaft.
    [0004] 10 Structure of the Type A Control Bar Drive Heavy Duty Enclosure: The Type A Control Bar Drive Heavy Duty Enclosure consists of parts, such as the Exhaust Valve 1, the end plug 2, the race sleeve 3, the enclosure 4, the T-threaded connection 8, the penetration part 5, etc. The threaded connection T 8 is connected to the enclosure 4 by the T-thread, sealing by the weld f2. The connection mode and the similar sealing mode are applicable between the race sleeve 3 and the enclosure 4, between the end cap 2 and the race sleeve 3.
    [0005] The end weld is applicable between the T-threaded connector 8 and the penetration member 5. In this way, the drive mechanism of the type A control rods is formed by the weld joined by the three f2 welds (either the upper, central and lower welds) and an end weld, the structures of which are given in FIGS. 2, 3, 4, 5. Structure of the resistant enclosure of the drive mechanism of the control rods of the type B: The enclosure 4 and the penetration piece 5 of the type B control rod drive mechanism will be welded directly end-to-end (ie the integral enclosure penetration part) by canceling the bottom weld f2. The race sleeve 3 is machined into a deep blind hole by means of the forging part by canceling the upper weld f2 (ie the integral deep blind hole race sleeve). The type of threading connection indicated in type A and the weld sealing mode S2 are continued to be used between the race sleeve 3 and the enclosure 4. The structures of the strong enclosure of the drive mechanism of the Type B control rods are given in Figures 6 and 7, including a S2 weld and a butt weld. The drive mechanism of the REP control rods operates in the high temperature, high pressure and radiation environment. Therefore, the resistant housing of the control rod drive mechanism which is one of the pressure boundary, must meet the requirements for resistance to high temperature, high temperature, stress, corrosion, etc. And it is desirable to have fewer welds and to have solid and reliable structure. The resistant enclosure of the drive mechanism of the control rods 15 of type A consists of exhaust valve 1, end cap 2, race sleeve 3, enclosure 4, threaded connection T 8 and penetration piece 5, etc. It is formed by the weld joined by the three S2 welds (the upper, the middle and the bottom welds) and a different metal end weld. These three welds S2 are the weak links of the whole resistant enclosure risking the leakage through the crack caused by stress and corrosion. In addition, the exhaust valve 1 and the end plug 2 adopt the mechanical hard seal requiring the high accuracies of the sealed conical surface to be hard to cut between both, and increasing the difficulty of manufacture. Due to the low reliability of the mechanical connection, there is a risk of wear of the sealing surface or insufficient tightening of the plug thread, as well as leakage of reactor coolants under high temperature and high temperature conditions. 30 pressure. The enclosure 4 of the drive mechanism of the control rods of type B is austenitic steel, while the penetration piece 5 is made of nickel-based alloy. Structurally, using butt welding of dissimilar metals, it is able to weld 3032058 4 the enclosure 4 and the penetration piece 5 together to cancel the bottom weld S2 in the old type A structure. The sleeve stroke 3 adopts the austenitic stainless steel material and will be designed into a deep blind hole structure to cancel the upper weld S2. Compared with the resistant enclosure of the Type A control rod drive mechanism, Type B has reduced two S2 welds significantly improving safety. However, it still risks leakage in the central weld S2. And there is a different steel between the enclosure 4 and the penetration part 5, thus causing the great difficulty of manufacturing end welding, the high control costs, and always risking problems such as cracking welds, etc. Therefore, it is necessary to design a more secure and reliable resistant enclosure structure in order to reduce the risks of leakage and the difficulties of machining and manufacture of the resistant enclosure, and to gain real values of application. in projects. The object of the present invention to solve the technical problems is to provide a strong nickel-based alloy enclosure 20 and its method of implementation which are characterized by the improvement of safety, the reduction of maintenance difficulty and the reduction of production costs. In order to solve the above-mentioned problems, the present invention adopts the following technical solution: A strong nickel-based alloy enclosure, comprising the integral enclosure penetration part which is machined and fabricated by the nickel-based alloy forging , and the integral deep hole blind hole race sleeve. The integral enclosure penetration part is formed by the integral enclosure part and the penetration part. (Integral deep blind hole race sleeve to blind hole structure completely closed at the top in block). The integral enclosure penetration piece and the integral deep blind hole race sleeve are connected through the thread and will be sealed by the nickel-based alloy weld. Said sleeve 3032058 integral integral blind hole race is machined and manufactured by the nickel-based alloy forging or by the austenitic stainless steel forgings. When the integral deep blind hole race sleeve is machined and manufactured by the austenitic stainless steel forging, a nickel-based alloy ring is pre-welded into the connection location between said integral integral blind hole race sleeve. and the integral piece of enclosure penetration. Said nickel-based alloy weld intended to seal the clearance between the integral deep blind hole raceway sleeve 10 and the integral enclosure penetration part, will be implanted between the nickel-based alloy ring and the enclosure of the integral part of enclosure penetration. The integral enclosure penetration part according to the present invention is machined and fabricated by the integral nickel alloy forging to completely cancel the butt weld between the enclosure and the penetration piece, exhaustively eliminate the risk of leakage from welding, improve the safety of the entire enclosure, further reduce the difficulty of maintenance of nuclear power plants, manufacturing and maintenance costs, simplify the work of the mechanism control rods during in-service control, and improve the performance of resistance to high temperature and corrosion. The weld in the center of the strong enclosure is nickel-based alloy. The parts in the integral enclosure penetration piece and in the integral deep-hole blind race sleeve necessary to contact with the nickel-based alloy welding materials are nickel-based alloys. As a result, the nickel-based alloy weld significantly increases the stress and corrosion resistance and reduces the risk of leakage from the welds. Advantageously, the welded chamfer S2 intended to form the weld S2 is implanted in the enclosure between said integral deep blind hole race sleeve and the integral chamber penetration part. When the Integral 3032058 6 Integral Deep Hole Stroke Sleeve is machined and manufactured by the austenitic stainless steel forgings, the welded S2 chamfer on the Integral Integral Borehole Stroke sleeve is machined and formed by the alloy-based alloy ring. nickel which is welded on the integral 5-hole blind hole race sleeve. And the integral deep-hole blind hole sleeve with machined S2 welded chamfer and enclosure of integral enclosure penetration part are connected by the thread, and will be S2-welded to nickel-based alloy. As the integral deep blind hole race sleeve 10 is nickel-based alloy for forming welded seam S2 of weld S2 (said welded seam S2 is naturally nickel-based alloy when sleeve is machined and manufactured by nickel-plated alloy forging, while said welded S2 bevel will thus be nickel-based alloy due to machining and fabrication by the nickel-based alloy ring which is welded to the race sleeve of Integral deep blind hole when integral integral blind hole race sleeve is machined and manufactured by austenitic stainless steel forgings.) Integral enclosure penetration part is made of nickel-based alloy, whose welding material is nickel-based alloy. As a result, the S2 weld from here is that of a nickel-based alloy. The stress-resistant and the corrosion-resistant are considerably improved compared to the austenitic stainless steel S2 welding of the type B heavy-duty enclosure. If the thickness of the welding lug 25 is suitably increased for S2 welding from here, it would be able to significantly reduce the risk of leakage from the welds, and do not cause the adverse influence on S2 solder stripping necessary to achieve later. Advantageously, it is capable of not providing the welded chamfer S2 between the integral deep blind hole race sleeve and the enclosure of the integral enclosure penetration part. The angular weld is used to make the connection between the integral deep blind hole race sleeve and the enclosure of the integral enclosure penetration part to replace the S2 weld between the old 3032058 7 enclosure and the race sleeve to reduce more the risks of leakage from welding in the resistant enclosure. Through the comparison of mechanical performance between the nickel-based alloy (eg Incone1690) and the austenitic stainless steel (eg 00Cr18NilON), the Incone1690 nickel-based alloy has mechanical performance characteristics at room temperature and those at high temperatures of 350 ° C that are better than those of 00Cr18NilON steel. However, the steady state temperature of the resistive enclosure is about 310 ° C. Clearly, the heavy-duty nickel-based alloy enclosure has better mechanical and stress and corrosion-resistant performance than the traditional austenitic stainless steel enclosure. The method of operating said strong nickel-based alloy housing comprises the following steps: S 1. Using the nickel-based alloy forgings according to machining and forming the integral enclosure penetration part; S2. Use the 20-based nickel-based alloy forgings to machine and completely form the integral deep blind hole race sleeve; or use the stainless steel forgings according to machining and preliminarily form the integral deepened blind hole race sleeve, and then weld the nickel-based alloy ring on the solid 25 of the integral integral deep blind hole race sleeve preliminarily, and then complete the complete machining of the deep integral blind hole race sleeve; S3. When mounting the on-site control rod drive mechanisms of the nuclear power plant, first mount the hook components on the integral enclosure penetration part, and then use the enclosure to penetrate the end of the enclosure. locating between the integral enclosure penetration part and the integral deep blind hole race sleeve, and terminating the coupling between both by the threading; 3032058 8 S4. Use the nickel-based alloy welding wire or the nickel-based alloy filler ring to fill the f2 weld between the integral enclosure penetration part and the integral integral blind hole race sleeve; 5 Or, if the f2 seamless structure is used, directly use the nickel-based alloy materials to weld the integral enclosure penetration part and the integral integral blind hole race sleeve. In summary, the beneficial effects of the present invention are as follows: 1. The enclosure penetration piece is a nickel-based alloy for improving high temperature and corrosion resistance. 2. The integral enclosure penetration part takes the enclosure 15 and the penetration part as an integral part to directly perform the machining to cancel the existing weld between the resistant housing of the control rod drive mechanism and the penetration piece, in order to reduce not only the butt welding processes between the resistant B-type enclosure and the penetration piece, but also to exhaustively eliminate the risks of leaking from welding, improve the safety of the entire enclosure, further reduce the maintenance difficulty of nuclear power plants, manufacturing and maintenance costs, simplify the work of the control bar mechanism during in-service control, while significantly reducing the difficulty of manufacture of enclosure and having economic advantages. For the integral enclosure penetration part and the integral deep blind hole race sleeve, in case of partial or total replacement of 30 00Cr18NilON austenitic stainless steel by the nickel-based alloy (eg Incone1690) at a relatively high cost despite the rising cost of materials, manufacturing and maintenance costs are significantly reduced in relation to material costs. Generally, the resistive enclosure according to the present invention has the costs, safety and simplicity better than the type A and type B resistant enclosure mentioned above. In addition, the nickel-based alloy (eg Incone1690) has better high temperature and corrosion resistance than stainless steel (eg 00Cr18NilON), which means that the alloy has the higher sustainable stability in NPP regime. And it is a better choice for nuclear equipment (eg its control bar drive mechanism) that requires longer life in the future. 3. In the nuclear power plant, the weakest link S2 ring weld is likely to produce leakage caused by the leak. However, the ring weld S2 in the center of the strong enclosure according to the present invention or the angular weld is made of nickel-based alloy. Parts in the integral enclosure penetration part and in the integral deep blind hole race sleeve necessary to contact with the nickel-based alloy welding materials are nickel-based alloys. As a result, the nickel-based alloy weld significantly increases the stress and corrosion resistance and reduces the risk of leakage from the welds. 4. The enclosure of the present invention is formed by welding two parts, the integral enclosure penetration part and the integral integral blind hole race sleeve. A solder (S2 ring weld or angular weld) is used to integrate the enclosure and its penetration piece together to perform the machining, and then to weld with the race sleeve to reduce the amount of welding to thus reducing the risks of failure caused by the corrosion leakage of the welds. 5. Since the race sleeve and the enclosure are connected by the T-thread and the S2 ring weld, the S2 ring has excellent elasticity for the control bar drive mechanism. a great difficulty S2 ring sealing welding, and a greater difficulty sealing S2 ring sealing of different alloy. As a result, 3032058 10 it is amazing to replace the material of the components of the resistant enclosure because of the technical problems of the great difficulty of S2 ring sealing of different alloy alloy. For example, when the austenitic stainless steel (for example 00Cr18NilON) is usable in the race sleeve, while the enclosure is made of nickel alloy, for example Incone1690, the welding S2 between both is precisely S2 ring seal made of different alloy which has a great difficulty of welding and performance difficult to guarantee. However, the present invention proposes to weld a nickel-based alloy ring in the ring weld S2 of the race sleeve to first machined in chamfer S2 and then ring welded S2 with the enclosure. Since the S2 ring seal welding is the same type of alloy welding, it is thus able to avoid the difficulty between the different existing alloys in the type B resistant enclosure in order to improve the welding quality. ring S2. At the same time, the ring weld S2 is a nickel-based alloy whose mechanical characteristics and those of corrosion resistance are better than those in the S2 stainless steel ring weld in the enclosure 20 of the type B and in the type B case. 6. When the race sleeve and the enclosure are made of nickel-based alloy, the angular welding is directly applicable between the race sleeve and the enclosure to avoid the ring welding problem S2.

According to the exemplary embodiments and the accompanying figures below, the present invention will be further described in detail, and embodiments of the present invention are not so limited thereto. Referring to FIG. 8, a heavy-duty nickel-based alloy enclosure includes the integral enclosure penetration piece 9 which is machined and fabricated by the nickel base alloy forging member 3032058 and the race sleeve Integral blind blind hole 10. The integral enclosure penetration piece 9 is formed by the integral enclosure portion and the penetration portion. Integral seamless enclosure penetration part 9 is machined and formed by the integral nickel alloy forging (eg Incone1690), i.e. to use the workpiece integrating machine forged from an integral nickel-based alloy to be machined and fabricate the two traditional components, the enclosure and the penetration piece, to completely cancel the butt weld between the enclosure and the penetration piece, e.g. Steel butt welding different from the B enclosure, and improve the completed and the structural safety, and greatly reduce the difficulty of manufacture. Integral deep blind hole race sleeve 10 to the 15 blind hole structure closed completely up block. The integral enclosure penetration part 9 and the integral deep blind hole race sleeve 10 are connected by the threading and will be sealed by the nickel-based alloy weld. Said integral deep blind hole race sleeve 10 is machined and manufactured by the nickel-based alloy forging or by the austenitic stainless steel forgings, i.e. integral nickel base or that of austenitic stainless steel to be machined and manufactured in deep blind hole structure. When the deep integral blind blind race sleeve 10 is machined and manufactured by the austenitic stainless steel forging, a nickel-based alloy ring 11 is pre-welded into the connection location between the blind hole race sleeve. 10 and the integral enclosure penetration part 9, see FIG. 9. Said nickel-based alloy weld intended to seal the clearance between the integral deep blind hole race sleeve 10 and the integral part 9, will be implanted between the nickel-based alloy ring 11 and the enclosure of the integral chamber penetration part 9.
    [0008] The welded chamfer S2 for forming the weld S2 is implanted in the enclosure between said integral deepened blind hole race sleeve 10 and the integral enclosure penetration part 9, see FIGS. 8, 11 and 12. Integral integral blind hole 5 race sleeve 10 is machined and manufactured by the nickel-based alloy forging, said S2 welded chamfer is machined directly by the integral deep-hole blind hole sleeve 10. When the deep-hole blind hole race sleeve 10 is machined and manufactured by the austenitic stainless steel forging, said welded chamfer S2 on the integral deep blind hole race sleeve 10 is machined and formed by the nickel-based alloy ring 11 which is welded to the Integral blind blind hole sleeve 10, see FIG. 9, the part of which is indicated by the broken line is the structure of welded chamfer S2. Integral deep blind borehole sleeve 10 with machined S2 welded chamfer has the same structure as the integral deep blind borehole race sleeve of the Type B control rod drive mechanism. Compared to the blind hole race sleeve In the case of the integral control mechanism 20 of the B-type control rods, the differences are as follows: the welded chamfer S2 of said integral deep blind raceway sleeve 10 is made of nickel-based alloy. Integral deep blind hole race sleeve 10 with welded S2 welded bevel and enclosure of integral enclosure penetration part 25 are connected by the T-thread, and will be S2 welded to nickel-based alloy weld . As the integral deepened blind hole race sleeve 10 is nickel-based alloy intended to form welded S2 bevel of the S2 weld (said S2 welded seam is naturally made of nickel-based alloy when the deep-hole blind hole sleeve integral 10 is machined and manufactured by the nickel-based alloy forging, while said welded chamfer S2 will thus be nickel-based alloy due to machining and fabrication by the nickel-based alloy ring 11 which is welded to the sleeve 3032058 14 integral integral blind hole race 10 when the integral deep blind hole race sleeve 10 is machined and manufactured by the austenitic stainless steel forgings. The integral enclosure penetration part 9 is made of nickel-based alloy, the welding material of which is made of nickel-based alloy. As a result, the S2 weld from here is that of a nickel-based alloy whose stress-resistance and corrosion-resistance are considerably improved compared to those of S2 welding in austenitic stainless steel of the resistant enclosure of the type B. If the thickness of the solder lug 10 is suitably increased for the S2 weld from here, it would be able to considerably reduce the risk of leakage from the welds, and not to cause the adverse influence on soldering stripping S2 necessary to achieve later. When said deep integral blind hole race sleeve 10 is machined and fabricated by the nickel-based alloy forging, it is formed by the structure of the blind hole machined by the nickel-based alloy forging to machine the welded chamfer S.2. When the integral integral deep-hole blind race sleeve 10 is machined and manufactured by the austenitic stainless steel forging, a nickel-based alloy ring (eg Incone1690) is welded into the location where the blind hole race sleeve Integral integral 10 is connected to the enclosure of the integral enclosure penetration part 9 by means of welding, and then a welded chamfer S2 will be machined on the nickel-based alloy ring 11. that is, it is necessary to weld a nickel-based alloy ring (eg Incone1690) in the proper location of the austenitic stainless steel race sleeve, and then to machine the S2 welded bevel based on said ring, see FIG. 9. Concretely, before machining the welded chamfer S2 of the integral deep blind blind hole raceway 10 in austenitic stainless steel, the alloy welding material should first be used. nickel-based to achieve the circular welding of the nickel-based alloy (eg Incone1690) in 3032058 15 the integral deep-hole blind hole race sleeve 10 austenitic stainless steel (eg 00Cr18NilON), and then to do the nickel-based alloy ring 11 and the welding zone together form the welded S2 nickel-based alloy bevel 5 of the integral deep blind hole race sleeve 10 by means of the machining mode. It is able not to provide the S2 welded chamfer between the integral deep blind hole race sleeve 10 and the enclosure of the integral enclosure penetration piece 9. The angular seal is used to make the connection between the race sleeve. Integral deep blind hole 10 and enclosure of the integral enclosure penetration chamber 9, see Figure 10, to replace the S2 weld between the old enclosure and the race sleeve to further reduce the risk of leakage from welding in the resistant enclosure. Said nickel-based alloy is Incone1690 or the other nickel-based alloy. Through the comparison of mechanical performance between the nickel-based alloy (eg Incone1690) and the austenitic stainless steel (eg 00Cr18NilON), the Incone1690 nickel-based alloy has mechanical performance characteristics at room temperature. and those at high temperatures of 350 ° C that are better than those of 00Cr18NilON steel. However, the steady state temperature of the resistive enclosure is about 310 ° C. Clearly, the heavy-duty nickel-based alloy enclosure has better mechanical and stress and corrosion-resistant performance than the traditional austenitic stainless steel enclosure. The resistive enclosure according to the present invention is machined by the Incone1690 integral nickel alloy forging by completely canceling the butt weld between the enclosure and the penetration piece. The method of implementing said strong nickel-base alloy enclosure comprises the following steps: 3032058 16 Using the nickel-based alloy forgings conforming to machining and forming the integral enclosure penetration part 9; S2. Use the nickel-based alloy forgings 5 in accordance with machining and completely form the integral integral 10-hole blind race sleeve; or use the stainless steel forgings according to machining and preliminarily form the integral deepened blind hole race sleeve 10, and then weld the nickel-based alloy ring 11 out of 10 the integrally machined integral deep-hole blind hole race sleeve 10 , and then perform liquid penetration control, ultrasonic testing, radiation control and dimensional stabilization processing in accordance with national and international standards, and finish the complete machining of the sleeve 15 in-depth integral blind hole race 10 Said dimensional stabilization treatment is a general technical means in the present field, concretely, means the thermal stabilization treatment of the dimensions. During actual operation, he is able to adjust the concrete parameters according to the actual materials and the residual machining stresses. An example of a parameter is given here: raise the temperature up to 300 to 500 ° C at the speed of about 1 ° C / min, maintain the temperature for 9 to 14h, and then cool the boiler to 120 to 170 ° C and then cool the air; S3. When mounting the on-site control bar drive mechanisms of the nuclear power plant, first mount the hook components on the integral enclosure penetration part 9, and then use the enclosure to penetrate the end. locating between the integral enclosure penetration part 9 and the integral deep blind hole running sleeve 10, and terminating the coupling between all of them by the threading; S4. Use the nickel-based alloy welding wire or the nickel-based alloy filler ring to fill the solder f2 between the integral enclosure penetration part 9 and the integral deep blind hole race sleeve 10; 3032058 17 Or if S2 solderless structure is used, directly use the nickel-based alloy materials to weld the integral enclosure penetration part 9 and the integral deep-hole blind race sleeve 10.
