[0030] The following is a further detailed description of the implementation of the present application in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but cannot be used to limit the scope of the present application.

[0031] The various specific technical features and embodiments described in the specific implementation methods can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features / embodiments in this application are no longer described separately. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The application is further described in detail below in conjunction with the drawings and specific embodiments.

[0032] To facilitate understanding of the anode 100 provided in the embodiment of the present application, the electrolysis device provided in the embodiment of the present application is first described:

[0033] The present application provides an electrolysis device, including an electrolytic cell, a cathode, and an anode 100 in any embodiment of the present application. The electrolytic cell is formed with an electrolytic chamber; part of the cathode is arranged in the electrolytic chamber; and the conductive mesh basket 10 of the anode 100 is located in the electrolytic chamber.

[0034] Molten salt constitutes the electrolyte and is arranged in the electrolysis chamber. The electrolyte refers to a compound that can conduct electricity in a molten state. Molten salt refers to a molten body formed after the salt is melted, such as the molten body of alkali metal, alkaline earth metal halide, nitrate, and sulfate. Molten salt has good stability in a high temperature environment and low viscosity, which is beneficial to electron migration.

[0035] The electrolysis device electrolyzes uranium oxide and molten salt through the cathode and anode 100. Specifically, the anode 100 and the cathode are electrically connected to a DC power supply, and the DC power is transmitted to the uranium oxide and the molten salt through the cathode and the anode 100. After the DC power is passed into the molten salt, the ions in the molten salt move in a directional manner, the cations in the molten salt move toward the cathode, the cathode absorbs electrons and undergoes a reduction reaction to generate new substances; the anions in the molten salt move toward the anode 100, the anode 100 releases electrons and undergoes an oxidation reaction to generate new substances.

[0036] The uranium oxide structure refers to a structure made of uranium oxide. Exemplarily, the cathode includes a cathode basket, and the cathode basket is used to place the uranium oxide.

[0037] In one embodiment, the electrolysis device includes a heating element, which is used to heat the molten salt in the electrolysis chamber to keep the molten salt in a molten state. Exemplarily, the heating temperature of the heating element is between 600° C. (Celsius) and 900° C., so that the molten salt can remain in a molten state.

[0038] In the related technology, during the electrolytic reduction of oxide spent fuel, oxygen ions eventually lose electrons at the anode, and choosing a suitable anode becomes one of the key issues in the electro-reduction process. In general, the anode needs to meet the following requirements: good conductivity, stability to molten salts, good electrochemical stability, resistance to corrosion by chlorine, oxygen and oxygen ions; high current density to oxygen ions, good mechanical and thermal stability; and also needs to have the characteristics of low cost, no pollution, and easy assembly. Currently, the most commonly used anode is the platinum anode, followed by the graphite anode. Others include glassy carbon electrodes, SnO 2 、BDD、La0.33Sr0.67MnO 3 , Inconel 600, 700, 316 stainless steel, W, Mo, Ti, TiN, Sb, Rh, Pd, Ir and Au, etc. Platinum anode, as an inert electrode, is widely used in the electrolytic reduction of uranium oxide. During the reaction, lithium platinum oxide will be generated on the surface of the platinum anode. This layer of oxide has no effect on the current, but will gradually fall off as the reaction proceeds. Moreover, as an inert anode, oxygen or chlorine will be precipitated on the platinum anode. These gases will react with the metal in the electrolytic cell at high temperature, causing corrosion of the electrolytic cell. Carbon anode is popular because of its low price and reaction to produce CO / CO 2 Inert gases such as argon and niobium have been selected as potential anode materials, but their application prospects in uranium oxide electroreduction are not optimistic due to carbon contamination.

[0039] See also Figure 1 to Figure 2 The embodiment of the present application provides an anode 100 for electrochemical reduction of uranium oxide. The anode 100 includes a conductive mesh basket 10 and a conductive wire 20. The conductive mesh basket 10 is formed with a accommodating cavity 10a and a flow hole, and the flow hole is connected to the accommodating cavity 10a; the conductive wire 20 is connected to the conductive mesh basket 10, and the conductive wire 20 is used to transfer electrical energy to the conductive mesh basket 10.

[0040] The flow hole is in communication with the accommodation chamber 10 a , that is, the molten salt can flow into the accommodation chamber 10 a through the flow hole.

[0041] The conductive wire 20 is electrically connected to the conductive mesh basket 10 to transfer electrical energy to the conductive mesh basket 10. When the conductive mesh basket 10 is in a conductive state, uranium oxide is reduced with electrons to generate metallic uranium. The structure is simple and the cost can be reduced.

[0042] The conductive wire 20 can be used to fix the conductive mesh basket 10, thereby improving the structural stability of the anode 100. In addition, the conductive mesh basket 10 is easy to clean and can extend its service life, thereby further reducing production costs.

[0043] In the anode 100 provided in the embodiment of the present application, the conductive wire 20 is connected to the conductive mesh basket 10. The conductive wire 20 can transfer electrical energy to the conductive mesh basket 10. When the conductive mesh basket 10 is in a conductive state, uranium oxide is reduced by combining with electrons to generate metallic uranium. The conductive wire 20 can also fix the conductive mesh basket 10 to improve the structural stability of the anode 100. In addition, the conductive mesh basket 10 is easy to clean and can extend its service life, thereby reducing production costs.

[0044] In one embodiment, the diameter of the conductive thread 20 is between 0.5 mm (millimeter) and 5 mm. For example, the diameter of the conductive thread 20 can be 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm or 5 mm.

[0045] In one embodiment, the mesh number of the conductive mesh basket 10 is between 50 mesh and 1000 mesh. That is, the size of the flow hole is between 0.01 mm and 0.3 mm. Exemplarily, the size of the flow hole can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm or 0.3 mm, etc.

[0046] In one embodiment, the current density of the anode 100 is 0.001A / cm 2 (amperes / square centimeter) to 10A / cm 2 For example, the current density of the anode 100 may be 0.001 A / cm 2 , 0.1A / cm 2 , 1A / cm 2 , 5A / cm 2 Or 10A / cm 2 Etc. By setting a suitable current density, the electrolysis speed of the electrolysis device can be increased.

[0047] In some embodiments, the anode 100 includes a supply structure, which is placed in the housing chamber 10a and is used to provide electrons. In this way, during the oxidation reaction of the anode 100, more electrons can be generated at the anode 100 through the supply structure, thereby increasing the reduction reaction rate of the cathode, that is, increasing the generation rate of metallic uranium.

[0048] In some embodiments, the supply structure includes a metallic lithium structure. That is, the supply structure is a structure made of metallic lithium. In this way, on the one hand, no other additives need to be added to the molten salt, reducing the generation of impurities. On the other hand, metallic lithium can reduce impurities such as (OH-) hydroxide, water, oxygen and other metal ions, reducing the requirements for the water and oxygen content in the molten salt and the electrolytic cell in the electrolytic reduction process. On the other hand, the anode 100 does not generate active gas, which improves the corrosion resistance of the electrolytic device.

[0049] Exemplarily, the metallic lithium structure may be an analytically pure metallic lithium structure, that is, the purity of lithium in the metallic lithium structure is at least 99.7%.

[0050] Exemplarily, the metallic lithium structure may be roughly in the form of flakes or particles, thus increasing the contact area with the molten salt, thereby increasing the rate at which electrons move to the cathode and increasing the rate at which metallic uranium is generated.

[0051] For some examples, see Figure 1 The conductive wire 20 is passed through the conductive mesh basket 10 and is detachably connected to the conductive mesh basket 10. For example, the conductive wire 20 is passed through the flow hole, which is convenient for operators to pass the conductive wire 20 and fix the conductive mesh basket 10.

[0052] The conductive wire 20 is detachably connected to the conductive mesh basket 10. For example, please continue to refer to Figure 1 The conductive wire 20 can be wound and bound to the conductive mesh basket 10 to achieve a detachable connection. When the conductive wire 20 needs to be repaired or replaced, it is convenient for operators to load and unload the conductive wire 20 and the conductive mesh basket 10.

[0053] For some examples, see Figure 1 and Figure 2 The anode 100 includes an insulating tube 30, the insulating tube 30 forms a threading hole 30a, the conductive wire 20 is inserted into the threading hole 30a, the first end 20a of the conductive wire 20 extends out of the threading hole 30a, and the second end 20b of the conductive wire 20 extends out of the threading hole 30a and is connected to the conductive mesh basket 10. In other words, part of the conductive wire 20 is accommodated in the threading hole 30a, so that the insulating tube 30 plays a role in fixing the conductive wire 20, and to a certain extent, it can also reduce the impact of the high temperature environment on the conductive wire 20. In addition, the operator can move the conductive mesh basket 10 by holding the insulating tube 30, for example, take the conductive mesh basket 10 out of the molten salt, and the insulating tube 30 plays a better protective role.

[0054] The specific material of the insulating tube 30 is not limited. For example, the insulating tube 30 can be made of corundum (mainly including aluminum oxide), which has good high temperature resistance, long service life, and can reduce costs. For another example, the insulating tube 30 can be made of magnesium oxide, which has good high temperature resistance and insulation.

[0055] For some examples, see Figure 2 The anode 100 includes an insulating crucible 40, which forms a limited cavity 40a and a connecting hole, the connecting hole is connected to the limited cavity 40a, and the conductive mesh basket 10 is located in the limited cavity 40a. That is, the electrons generated by the metal lithium structure can move to the cathode through the flow hole and the connecting hole in sequence, and the molten salt can flow into the containing cavity 10a through the connecting hole and the flow hole in sequence.

[0056] The conductive mesh basket 10 is located in the limiting cavity 40a. On the one hand, under high temperature environment, the structure of metal lithium is in liquid phase, and the insulating crucible 40 can prevent the liquid metal lithium from flowing out of the limiting cavity 40a to a certain extent, playing a certain aggregation role. At the same time, it can also prevent impurities in the molten salt from contacting with the liquid metal lithium and causing pollution. On the other hand, when the conductive mesh basket 10 is powered on, the operator can hold the insulating crucible 40 to prevent accidental touching of the conductive mesh basket 10, and the insulating crucible 40 plays a better insulation protection role.

[0057] The specific material of the insulating crucible 40 is not limited. For example, the insulating crucible 40 can be made of corundum or magnesium oxide.

[0058] For some examples, see Figure 2 , the conductive wire 20 is connected to the insulating crucible 40. For example, please continue to refer to Figure 2 The second end 20b of the conductive wire 20 extending out of the threading hole 30a is sequentially penetrated by the flow hole and the connecting hole. The conductive wire 20 can be used to fix the insulating crucible 40, so that the structural stability of the anode 100 can be enhanced.

[0059] In one embodiment, the conductive wire 20 and the insulating crucible 40 are detachably connected. For example, see Figure 2 , the conductive wire 20 can be wound and bound to the insulating crucible 40. When the conductive wire 20 and the insulating crucible 40 need to be repaired or replaced, it is convenient for operators to load and unload the conductive wire 20 and the insulating crucible 40.

[0060] In some embodiments, the conductive wire 20 is made of metal molybdenum, metal tungsten or metal tantalum. In other words, the conductive wire 20 can be a structure made of metal molybdenum, metal tungsten or metal tantalum. Metal molybdenum, metal tungsten and metal tantalum are not easily oxidized, so that the anode 100 can be prevented from generating additional impurities during the power-on process.

[0061] In some embodiments, the conductive mesh basket 10 is made of stainless steel, metal nickel, metal molybdenum, metal tungsten or metal tantalum. For example, the conductive mesh basket 10 is made of stainless steel, which has good anti-oxidation ability and is not easy to rust. For another example, the conductive mesh basket 10 can be made of metal nickel, which has good conductivity and anti-oxidation ability.

[0062] In some embodiments, the electrolysis device includes a glove box, which includes a reaction chamber, and the electrolytic cell, cathode and anode 100 are all located in the reaction chamber. The reaction chamber is a sealed chamber, so that impurities such as dust and water vapor can be prevented from entering the reaction chamber, thereby reducing the impact of external factors on the electrolysis process.

[0063] In one embodiment, an inert gas is provided in the reaction chamber. The specific type of the inert gas is not limited, for example, it can be argon, so that an inert environment can be provided to prevent the cathode, anode 100 and other components from being oxidized in a high temperature environment.

[0064] In some embodiments, the electrolysis device includes an electrochemical workstation, and the cathode and anode 100 are both connected to the electrochemical workstation.
