[0003] Spent fuel refers to nuclear fuel that has been used in a reactor for a period of time and contains nuclides that can be recycled. This fuel is usually recycled and processed.

[0004] Currently, molten salt electrorefining is a common method for treating spent fuel and recycling it. This method primarily involves dissolving radionuclides in the spent fuel in the molten salt through an electrolytic reaction, which then precipitates out from the cathode. Furthermore, the cathode precipitate is recovered. However, recovering the precipitate presents a technical challenge. Existing industrial equipment for scraping and collecting electrolysis products is insufficient for this type of spent fuel treatment and requires modification. Summary of the Invention

[0027] Exemplary embodiments of the present application will be described below with reference to the accompanying drawings. For the sake of clarity and conciseness, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the process of developing any such actual implementation in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and these constraints may vary depending on the implementation.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application should have the common meanings understood by persons having ordinary skills in the field to which this application belongs.

[0030] In the description of the embodiments of the present application, “multiple” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In related technologies, during the electrolysis of spent fuel using the electrolysis device in molten salt electrorefining equipment, radionuclides containing molten salt are precipitated on the cathode. By scraping and collecting the precipitates on the cathode, the radionuclides in the spent fuel can be recovered. The selection of scraping tools is crucial for scraping and collecting the precipitates on the cathode. On the one hand, an inappropriate tool can break during the scraping process or damage other components of the molten salt electrorefining equipment. On the other hand, an inappropriate tool can prevent the precipitates from being scraped off the cathode.

[0032] In response to the above technical problems, an embodiment of the present application provides a method for designing a cutting tool for scraping off precipitates. The precipitates include electrolysis products generated on a cathode by electrolyzing molten salt. Figure 1 : is a flow chart of a method for designing a tool for scraping off precipitates according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps S10 to S70.

[0033] S10. Determine the scraping force applied to the precipitate.

[0034] S20. Determine the corrosive effect of the precipitates on the tool.

[0035] S30. Determine the physical and chemical properties of the precipitate.

[0036] S40. Determine the material of the tool based on scraping force, corrosion effect, and physical and chemical properties.

[0037] S50: Determine the shape characteristics of the precipitate and the shape characteristics of the cathode.

[0038] S60: Determine the movement mode of the cathode and the tool.

[0039] S70 , determining the structure of the tool according to the shape characteristics of the precipitate and the cathode determined in step S50 , the material determined in step S40 , and the movement mode determined in step S60 .

[0040] The embodiments of the present application determine the appropriate tool material by taking into account the scraping force required to be applied to the precipitate, the corrosive effect of the precipitate on the tool, and the physical and chemical properties of the precipitate. The tool structure is then determined based on the external features of the precipitate and the cathode, the material of the tool, and the movement of the cathode and tool. This helps ensure that the selected tool matches the difficulty of scraping the precipitate, so as to smoothly scrape the precipitate on the cathode, while avoiding breakage of the tool during the scraping process or damage to other components of the molten salt electrolytic refining equipment.

[0041] In some embodiments, since the tool is in direct contact with the precipitate during the scraping process, it needs to withstand greater cutting pressure and impact, and will be subjected to severe friction, so it is easy to generate very high cutting temperature. The material of the determined tool should meet the requirements of high hardness, sufficient strength and toughness, good wear resistance and corrosion resistance, good heat resistance and thermal conductivity, etc.

[0042] In such an embodiment, the material of the cutting tool may include, but is not limited to, tool steel, high-speed steel, cemented carbide, ceramic, and superhard material.

[0043] In some embodiments, the tool may be made of high-speed steel.

[0044] In some embodiments, the structure of a tool may include the basic form of the tool, the shape of the blades in the tool, and the size of the tool.

[0045] In some embodiments, basic forms of the cutting tool include but are not limited to integral type, welded type, machine clamped type and indexable type, among which welded type and indexable type cutting tools are more widely used.

[0046] In some embodiments, welded cutting tools primarily consist of a blade of a predetermined shape and a toolholder joined together through welding. These tools offer advantages such as a simple and compact structure, good tool rigidity, strong vibration resistance, ease of manufacture, and flexible use. However, due to the welding process during manufacturing, welded cutting tools often develop internal stress in the blade after cooling, making it prone to cracking and reducing cutting performance. Furthermore, the toolholder cannot be reused, requiring complete replacement if damaged.

[0047] In some embodiments, the indexable tool is a machine-clamped turning tool using an indexable insert, which is mainly composed of a tool shank, a tool pad, a blade and a clamping element. After one cutting edge of the blade becomes blunt, it can be quickly indexed and replaced with an adjacent new cutting edge. It has the advantages of long tool and tool shank life, short downtime for tool changing, resulting in high production efficiency, and low tool inventory requirements.

[0048] In the embodiment of the present application, the cutting tool needs to work in a high radiation environment and is difficult to replace, so an indexable cutting tool can be used.

[0049] In some embodiments, the shape of the blade includes but is not limited to a triangle, a triangle with an angle of 8°, a convex triangle, a regular quadrilateral, a pentagon, a parallelogram, or a rhombus.

[0050] In such an embodiment, the shape of the blade can be a regular quadrilateral, which has good versatility and the sharp angle of the blade is 90 degrees, so the blade strength and tool life are relatively high.

[0051] In some embodiments, the dimensions of the knife include the length of the blade and the angle of the blade.

[0052] In such an embodiment, the blade length refers to the theoretical side length of its geometric shape. Generally speaking, due to the rounded corners of the blade tip, the effective blade length of the blade is shorter than the blade length.

[0053] In such an embodiment, the blade angles include: rake angle, main clearance angle, main deflection angle, cutting edge inclination angle, secondary deflection angle, and secondary clearance angle. The rake angle is the angle between the front face of the tool and the base plane; the main deflection angle is the angle between the main cutting plane and the assumed working plane; and the cutting edge inclination angle is the angle between the main cutting edge and the base plane. For some cutting tools, such as indexable cutting tools, due to their special structure, the design of some angles is restricted by the shape of the insert, and only the rake angle, main deflection angle, and cutting edge inclination angle can be designed.

[0054] In some embodiments, in step S10, the following steps are further included: S11: determining the torque of the motor driving the cathode to rotate; S12: determining the scraping force according to the torque determined in step S11.

[0055] The embodiment of the present application determines the scraping force by the torque of the motor-driven cathode rotation, so that the determined scraping force can be consistent with the force required to be applied by the tool during the actual scraping operation, thereby ensuring the service life and scraping effect of the determined tool.

[0056] In some embodiments, in step S12, the scraping force satisfies the following expression (1):

[0057]

[0058] Among them, F c Indicates scraping force; T tot It indicates the torque of the motor driving the cathode to rotate when the tool is scraping the precipitate; T unl It represents the torque of the motor driving the cathode to rotate when the tool does not scrape the precipitate; r represents the radial distance from the point where the tool contacts the precipitate to the rotation center of the cathode; N ac Indicates the number of teeth of the motor's driving gear; N pa It represents the number of teeth of the driven gear driven by the driving gear; i represents the reduction ratio of the motor.

[0059] The method provided in the embodiment of the present application determines the scraping force of the tool through the above expression (1), which is conducive to ensuring that the tool involved can smoothly scrape off the precipitates on the cathode.

[0060] In some embodiments, step S30 further includes the following steps: S31: determining the sampling sites for physical and chemical analysis of the precipitate; S32: determining the number of sampling sites; S33: preparing different samples for determining the physical and chemical properties of the precipitate according to the analysis requirements of the physical and chemical analysis; S34: analyzing different samples to determine the metal content, salt content, and mechanical properties of the precipitate, wherein the physical and chemical properties include metal content, salt content, and mechanical properties.

[0061] The method provided in the embodiments of the present application can produce different samples for determining the physical and chemical properties of the precipitate by determining the sampling locations and the number of sampling locations for physical and chemical analysis of the precipitate, so that the produced samples can meet the analytical requirements of the physical and chemical analysis, thereby ensuring the accuracy and reliability of the determined metal content, salt content, and mechanical properties of the precipitate.

[0062] In some embodiments, the sampling site may be located at the upper or lower portion of the cathode.

[0063] In some embodiments, for the same position on the cathode, such as the upper portion of the cathode, the sampling site can be located at a deeper position on the upper portion of the cathode or at a shallower position on the upper portion of the cathode.

[0064] In some embodiments, in step S31 , the upper portion, the middle portion, and the bottom portion of the cathode are selected as sampling locations, respectively, to ensure that samples are prepared from the sampling locations.

[0065] In some embodiments, the movement mode of the tool is determined according to the movement mode of the cathode and the distribution of the precipitates on the cathode. Different tool movement modes can be determined according to different distribution modes of the precipitates on the cathode, which is beneficial to improving the scraping efficiency of the precipitates.

[0066] In some embodiments, the blade of the tool can be arranged to embrace the cathode, or can be arranged so that its sharp portion contacts the cathode, that is, the blade and the cathode can be in surface contact, point contact, or line contact.

[0067] The embodiments of the present application also provide an electrolysis product scraping and collecting device for collecting electrolysis products on the cathode. It is understood that the precipitates in the embodiments of the present application include electrolysis products. Figure 2 : is a structural diagram of the electrolysis product scraping and collecting device according to an embodiment of the present application, Figure 3 is a schematic structural diagram of the cathode according to an embodiment of the present application, such as Figure 2 and Figure 3 As shown, the electrolytic product scraping and collecting device 60 may include a receiving component 61 , a cutter 621 , a scraper moving component 622 and an electrolytic product collecting member 63 .

[0068] The accommodating assembly 61 is used to accommodate the cathode 20 and is configured to enable the cathode 20 to rotate. Electrolysis products are formed and attached to the cathode 20.

[0069] The cutter 621 is used to scrape off the electrolysis products on the cathode 20.

[0070] The scraper moving assembly 622 is used to drive the cutter 621 to move, so as to use the cutter 621 to scrape off the electrolysis products on the cathode 20 during the rotation process.

[0071] The electrolysis product collecting member 63 is configured to collect the electrolysis products scraped off during the scraping process of the cutter 621 and transfer the collected electrolysis products to the next process after the scraping is completed.

[0072] In the embodiment of the present application, the cathode 20 is accommodated by the accommodating assembly 61 and driven to rotate by the cathode 20, and the electrolysis products on the cathode 20 during the rotation are scraped off by the cutter 621, and then the scraped electrolysis products are collected by the electrolysis product collecting member 63 and transferred to the next process, which is conducive to the recovery of radionuclides in spent fuel. In addition, no operator participation is required during the recovery process, and the efficiency and safety are relatively high.

[0073] In some embodiments, again referring to Figure 3 The cathode 20 may include a first cathode body 21 and a second cathode body 22. The first cathode body 21 may be used for conducting electricity, and the second cathode body 22 may provide an attachment space for electrolysis products generated by the electrolysis reaction while conducting electricity.

[0074] In some embodiments, the first cathode body 21 and the second cathode body 22 are detachably connected to facilitate replacement of the second cathode body 22 and reuse of the first cathode body 21 .

[0075] In some embodiments, the electrolysis product collecting member 63 may be a collecting tray.

[0076] In some embodiments, the receiving assembly 61 may include a scraper container 611. The scraper container 611 has a receiving cavity, in which the cathode 20 is disposed, and the receiving cavity is used to provide a scraping space during the scraping process. The scraper container 611 has an opening 6111 formed on its body, so that the tool 621 can scrape the cathode 20 in the receiving cavity through the opening 6111.

[0077] In the embodiment of the present application, the cathode 20 is arranged in the accommodating cavity of the scraper container 611, and then the opening groove 6111 on the main body of the scraper container 611 is used to enable the tool 621 to scrape the cathode 20 in the accommodating cavity through the opening groove 6111, which helps to avoid the electrolytic products scraped off during the scraping process from splashing to the outside of the scraper container 611.

[0078] In some embodiments, the extension direction of the opening groove 6111 may be the same as the extension direction of the cathode 20 in the accommodating cavity, thereby facilitating the cutter 621 to fully scrape off the electrolysis products on the cathode 20 .

[0079] In some embodiments, the accommodating component 61 may further include a driving component 612; the scraper container 611 is formed with a mounting interface, the driving component 612 is connected to the scraper container 611 through the mounting interface, and a portion of the driving component 612 is disposed in the accommodating cavity, and the driving component 612 is configured to drive the cathode 20 to rotate.

[0080] In an embodiment of the present application, the drive component 612 is arranged at the mounting interface of the scraper container 611 so as to utilize the drive component 612 to drive the cathode 20 to rotate. Through the rotation of the cathode 20, each circumferential position of the cathode 20 can be fully in contact with the tool 621 during the scraping process, thereby facilitating the tool 621 to fully scrape the electrolysis products on the cathode 20.

[0081] In some embodiments, Figure 4 FIG. 1 is a schematic structural diagram of a driving component in a receiving component of an electrolysis product scraping and collecting device according to an embodiment of the present application, such as Figure 4 As shown, the driving assembly 612 may include a driving member 6121 , a first driving connecting member 6122 , a second driving connecting member 6123 and a scraper connecting member 6124 .

[0082] The driving member 6121 is used to drive the first driving connection member 6122 to rotate, and the driving member 6121 is arranged radially outside the scraper container 611 to avoid that there is no installation space for the driving member 6121 in the accommodating cavity of the scraper container 611.

[0083] The second drive connector 6123 is rotatably connected to the first drive connector 6122 . The second drive connector 6123 is configured to rotate along with the first drive connector 6122 during the rotation of the first drive connector 6122 .

[0084] The second driving connection member 6123 is also configured to drive the scraper connection member 6124 to rotate during the rotation process.

[0085] The scraper connector 6124 is configured to be detachably connected to the cathode 20 for driving the cathode 20 to rotate during the rotation process, and the scraper connector 6124 is disposed in the accommodating cavity.

[0086] In an embodiment of the present application, the first drive connector 6122 is arranged radially outside the scraper container 611, and then the drive member 6121 is used to drive the first drive connector 6122 to rotate, thereby indirectly driving the second drive connector 6123 connected to the first drive connector 6122 to rotate, thereby driving the cathode 20 to rotate. In this way, the cathode 20 can be driven when the space in the scraper container 611 is small and insufficient to be set up with the drive component 612; at the same time, part of the structure of the drive component 612 is arranged outside the scraper container 611, which is beneficial to avoid corrosion and extend its service life.

[0087] In some embodiments, the driving member 6121 can be a motor.

[0088] In some embodiments, the first drive connector 6122 and the second drive connector 6123 can be gears, and the gear radius of the first drive connector 6122 is larger than the gear radius of the second drive connector 6123, so as to reduce the rotational speed of the first drive connector 6122 and increase its torque, thereby improving the smoothness of the transmission.

[0089] In some embodiments, the scraper connector 6124 is formed with a cathode channel, which is connected to the accommodating cavity of the scraper container 611 so that the cathode 20 can enter the accommodating cavity through the cathode channel.

[0090] In some embodiments, the scraper connector 6124 may include a cathode clamping portion 61241 to clamp the cathode 20 when the cathode 20 is placed in the receiving cavity through the cathode channel.

[0091] In some embodiments, a clamping fitting portion 221 may be formed on the second cathode body 22 of the cathode 20, and the cathode clamping portion 61241 may specifically clamp the clamping fitting portion 221 of the second cathode body 22. In such an embodiment, the connection between the clamping fitting portion 221 and the cathode clamping portion 61241 helps reduce the travel of the cathode clamping portion 61241 and improve stability.

[0092] In some embodiments, the cathode clamping portion 61241 can be a three-jaw chuck.

[0093] In some embodiments, the cutter 621 is used to scrape off the electrolysis products on the cathode 20 ; the scraper moving assembly 622 is used to drive the cutter 621 to move, so as to use the cutter 621 to scrape off the electrolysis products on the cathode 20 during the rotation process.

[0094] In the embodiment of the present application, the scraper moving assembly 622 is used to drive the cutter 621 to move, which is beneficial for the cutter 621 to fully scrape the electrolysis products on the cathode 20 to achieve a better scraping effect.

[0095] In some embodiments, Figure 5 Schematic diagram of the structure of the cutter and scraper moving assembly of the electrolysis product scraping and collecting device according to an embodiment of the present application, as shown in FIG. Figure 5 As shown, the scraper moving assembly 622 may include a first scraper moving member 623, a second scraper moving member 624, and a scraper mounting frame 625. The first scraper moving member 623 is disposed on the scraper mounting frame 625; the second scraper moving member 624 is configured to be movable relative to the first scraper moving member 623 to move closer to or away from the scraper container 611; the cutter 621 is connected to the second scraper moving member 624, and the second scraper moving member 624 is further configured to enable the cutter 621 to move relative to the second scraper moving member 624.

[0096] In the embodiment of the present application, the first scraper moving member 623 and the second scraper moving member 624 cooperate with each other to enable the tool 621 to move flexibly, so that the tool 621 can fully scrape off the electrolysis products at various positions in the circumferential direction and extension direction of the cathode 20.

[0097] In some embodiments, the scraper moving assembly 622 may include two first scraper moving members 623 , and the two first scraper moving members 623 may be disposed in parallel on the scraper mounting frame 625 .

[0098] The two ends of the second scraper moving member 624 can be movably disposed on the two first scraper moving members 623 , respectively, to ensure that the tool 621 can remain stable when approaching or moving away from the scraper container 611 .

[0099] In some embodiments, the first scraper moving member 623 can be formed with a first sliding fitting portion 6231, and the second scraper moving member 624 can be formed with a first sliding portion 6241 on the side facing the first scraper moving member 623. Through the cooperation between the first sliding portion 6241 and the first sliding fitting portion 6231, the second scraper moving member 624 can be moved relative to the first scraper moving member 623.

[0100] In some embodiments, the scraper moving assembly 622 may further include a tool connecting member 626 . The tool 621 is connected to the second scraper moving member 624 via the tool connecting member 626 .

[0101] A second sliding fitting portion 6242 can be formed on the side of the second scraper moving member 624 facing away from the first scraper moving member 623, and the tool connecting member 626 can be formed with a second sliding portion 6261. Through the cooperation between the second sliding portion 6261 and the second sliding fitting portion 6242, the tool connecting member 626 can be moved relative to the second scraper moving member 624, thereby driving the tool 621 to move relative to the second scraper moving member 624.

[0102] In some embodiments, the first sliding fitting portion 6231 and the second sliding fitting portion 6242 may be slide rails, and the first sliding portion 6241 and the second sliding portion 6261 may be slide grooves.

[0103] In some embodiments, the electrolysis product scraping and collecting device 60 may further include a receiving and moving assembly 64 and a support member 72. The receiving and moving assembly 64 is disposed on the support member 72 and is configured to drive the electrolysis product collecting member 63 to move to the position of the cutter 621 to collect the scraped electrolysis product.

[0104] In the embodiment of the present application, the electrolysis product collecting member 63 can be moved without the intervention of an operator through the cooperation between the receiving moving component 64 and the supporting member 72, thereby achieving the purpose of collecting the scraped electrolysis products.

[0105] In some embodiments, after the scraping is completed, the receiving moving component 64 can drive the electrolysis product collecting member 63 away from the position of the cutting tool 621 to transfer the collected electrolysis products to the next process.

[0108] The embodiment of the present application fixes the receiving movable component 64 on the first support part 721, and then fixes the first support part 721 to the second support part 722 through the fixing component 723, thereby facilitating the overall disassembly and assembly of the receiving movable component 64 and the first support part 721; at the same time, the fixing component 723 is configured to be remotely operated, which is conducive to the operation of the robot, thereby reducing the involvement of the operator and improving safety.

[0109] In some embodiments, Figure 6 Schematic diagram of the structure of the fixed component in the support of the electrolysis product scraping and collecting device according to an embodiment of the present application, such as Figure 6 As shown, the fixing assembly 723 may include a fixing member 7231 , an operating connection member 7232 and an elastic member 7233 .

[0110] The fixing member 7231 is configured to be fixedly connected to the first support portion 721; the operating connection member 7232 passes through the fixing member 7231; the operating connection member 7232 includes a connecting portion 72321 and an operating portion 72322, the operating portion 72322 is configured to be remotely operated, and the connecting portion 72321 is configured to be fixedly connected to the second support portion 722 under the action of the operating portion 72322; the elastic member 7233 is disposed in the fixing member 7231 and is configured to elastically contact the first support portion 721, so as to apply a force to the operating connection member 7232 away from the second support portion 722 when the first support portion 721 and the second support portion 722 are disassembled.

[0111] The embodiment of the present application can facilitate operation by a robot by configuring the fixing assembly 723 to include a fixing part 7231, an operating connection part 7232 and an elastic part 7233. When the first support part 721 and the second support part 722 need to be disassembled, the disassembly can be performed by applying a force to the operating connection part 7232 away from the second support part 722, and the operation is relatively simple.

[0112] In some embodiments, the fixing member 7231 is formed with a through hole, and the operating connection member 7232 can extend into the through hole of the fixing member 7231 to penetrate the fixing member 7231.

[0113] In some embodiments, an operating engagement portion 72323 is formed on the connecting portion 72321 of the operating connector 7232. The size of the operating engagement portion 72323 is smaller than the inner diameter of the through-hole to prevent the operating connector 7232 from passing through the through-hole of the fixing member 7231. The elastic member 7233 is disposed within the fixing member 7231, and both ends of the elastic member 7233 are in elastic contact with the first supporting portion 721 and the operating engagement portion 72323, respectively.

[0114] In some embodiments, the fixing member 7231 is detachably connected to the first support portion 721. For example, the fixing member 7231 can be connected to the first support portion 721 via bolts.

[0115] In some embodiments, the connecting portion 72321 may be connected to the second supporting portion 722. For example, one end of the connecting portion 72321 away from the operating portion 72322 may be provided with a thread to connect to the second supporting portion 722.

[0116] When connecting the first support part 721 and the second support part 722, the fixing part 7231 can be connected to the first support part 721 by bolts first, and then the connecting part 72321 can be connected to the second support part 722 by screwing the operating part 72322. At this time, the elastic part 7233 will be deformed by the pressure applied to it by the operating matching part 72323.

[0117] When disassembling the first support portion 721 and the second support portion 722, the fixing member 7231 and the first support portion 721 can be disassembled first, and then the operating portion 72322 can be twisted to separate the connecting portion 72321 from the second support portion 722. At this time, the elastic member 7233 can apply a force to the operating matching portion 72323 away from the second support portion 722, thereby popping out the fixing member 7231 and the operating connecting member 7232 as a whole.

[0118] In some embodiments, as Figure 2 and Figure 4As shown, the electrolysis product scraping and collecting device 60 may further include a receiving and mounting member 65 for mounting the receiving assembly 61 ; the receiving and mounting member 65 is formed with a mounting support portion 651 for supporting the cathode 20 .

[0119] In some embodiments, the second driving member 6121 in the fixing assembly 723 can be fixedly disposed on the accommodating mounting member 65 .

[0120] In some embodiments, the mounting support portion 651 is formed with a through channel 652 corresponding to the cathode channel, and the cathode 20 can be placed in the accommodating cavity of the scraper container 611 via the through channel 652 and the cathode channel.

[0121] like Figure 3 As shown, a cathode support portion 23 may be formed on the first cathode body 21 of the cathode 20. When the cathode 20 is placed in the accommodating cavity of the scraper container 611 via the through channel 652 and the cathode channel, the mounting support portion 651 can be used to support the cathode support portion 23 of the cathode 20.

[0122] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0123] The above description is only a specific implementation method of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
