Description

Technical Field

[0001] This invention relates to the field of nuclear fuel reprocessing technology, and more specifically, to a system for the transfer of radioactive waste resin. Background Technology

[0002] In spent fuel reprocessing plants, the water in spent fuel storage pools is mostly purified using ion exchange resins. When the exchange capacity of the ion exchange resin decreases, the resin bed fails to achieve the required purification effect, or the pressure difference across the exchange column reaches a certain value, the resin needs to be replaced. Therefore, waste resin is one of the main low- and intermediate-level radioactive wastes generated in reprocessing facilities.

[0003] With the continuous development of nuclear energy, the demand for spent fuel reprocessing plants is also increasing. Because the location and form of waste resin storage tanks in reprocessing plants differ significantly from those in nuclear power plants, the previous waste resin transportation systems used in nuclear power plants are not suitable for nuclear fuel reprocessing facilities. For example, using vacuum suction requires waste resin storage tanks to be located near transfer tank trucks, with an elevation difference generally not exceeding 10 meters. If the elevation difference is too high, intermediate tanks are needed for transfer and suction, increasing the complexity of the entire system. However, the elevation difference in spent fuel reprocessing facilities typically exceeds 15 meters. Furthermore, since waste resin storage tanks are mostly located in underground equipment rooms, personnel cannot directly inspect them, making pumping or other moving equipment unsuitable for transporting waste resin.

[0004] In view of the above technical problems, this invention is hereby introduced. Summary of the Invention

[0005] The main objective of this invention is to provide a maintenance-free waste resin conveying system suitable for the transfer of radioactive waste resin in spent fuel reprocessing plants.

[0006] To achieve the above objectives, this invention provides a radioactive waste resin transfer system, comprising a transfer device, a feeding unit, and a discharging unit. The transfer device includes a tank truck shielded container, which receives waste resin from the feeding unit and transfers it to the discharging unit. The feeding unit includes: a first waste resin collection tank containing waste resin; a first ejector that draws waste resin from the collection tank into the tank truck shielded container; and a first pump that provides first motive water to the ejector. This invention employs a purely mechanical ejector structure, achieving maintenance-free resin transport.

[0007] The following are further optimizations of the above solution by the present invention:

[0008] Furthermore, the feeding unit includes a first water storage tank, from which the first power water originates, and after use, the first power water flows back to the first water storage tank.

[0009] Furthermore, the transfer device also includes a second jet injector. The first pump provides the second jet injector with second motive water, which comes from the first water storage tank. After passing through the tank truck's shielded container, the second motive water is pumped and transported to the first water storage tank.

[0010] Furthermore, the unloading unit includes a second pump and a second waste resin collection tank. The second pump provides third power water to the second ejector, which then transports the waste resin to the second waste resin collection tank.

[0011] Furthermore, the unloading unit also includes a second water storage tank, which provides a third source of motive water. This third motive water is pumped and transported to the second water storage tank after passing through the tank truck's shielding container. By designing the water storage tank and related pipelines and valves, the motive water for the waste resin is recycled during the loading and unloading process, thereby effectively reducing the amount of radioactive wastewater generated in the process.

[0012] Furthermore, the transfer system includes a first pipe and a second pipe, and the feeding unit and the transfer device are connected through the first pipe and the second pipe.

[0013] Furthermore, the transfer system includes a third pipe and a fourth pipe, with the third pipe connected to deionized water and the fourth pipe connected to compressed air.

[0014] Furthermore, the transfer device includes a fifth pipe for conveying waste resin, the feeding device includes a sixth pipe for conveying waste resin, and the unloading device includes a seventh pipe for conveying waste resin. Deionized water and compressed air are used to clean any one or more of the first, second, fifth, sixth, and seventh pipes.

[0015] Furthermore, the transfer system includes multiple valves, which enable the opening and closing of any one or more of the first, second, third, fourth, fifth, sixth, and seventh pipelines.

[0016] Furthermore, the first pump is a centrifugal pump.

[0017] Furthermore, the second pump is a screw pump.

[0018] According to another aspect of the present invention, a transfer method for a waste resin transfer system is also provided, wherein the waste resin transfer system is any of the transfer systems described above, and the transfer method includes the following steps:

[0019] Feeding unit docking step S1: Connect the feeding unit to the transfer device;

[0022] Power water recovery step S4: Provide second power water to the second jet injector, and transport the first power water and the second power water to the first water storage tank through the second jet injector;

[0023] Loading quantity judgment step S5: Check whether the resin loading quantity in the tank truck shielding container meets the requirements. If it does not meet the requirements, repeat the first resin transfer step S3 and the kinetic water recovery step S4.

[0024] Feed pipe cleaning S6: Rinse any one or more of the first, second, fifth, and sixth pipes with deionized water;

[0025] First purging step S7: Use compressed air to purge any one or more of the first, second, third, and fourth pipes;

[0026] Unloading start-up step S8: Connect the tank truck shielding container to the unloading unit;

[0027] Unloading and water filling step S9: Fill the tank truck shielded container with water to enhance the flowability of waste resin;

[0028] Second resin transfer step S10: Transfer the waste resin in the tank truck shielded container to the second waste resin collection tank;

[0029] Residual Amount Judgment Step S11: Check whether the residual amount of waste resin in the tank truck shielding container meets the requirements. If it does not meet the requirements, repeat the unloading and water filling step S9 and the second resin transfer step S10.

[0030] Unloading pipe cleaning step S12: Rinse any one or more pipes from the first, second, fifth, and seventh pipes with deionized water;

[0031] Second purging step S13: Purge any one or more of the first, second, fifth, and seventh pipes with compressed air.

[0032] By applying the technical solution of this invention, at least the following beneficial effects are achieved:

[0033] 1. The waste resin transfer system of this invention, based on the layout characteristics of spent fuel reprocessing plants, uses an ejector as the power equipment for waste resin transfer.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0047] This invention proposes a radioactive waste resin transfer system suitable for spent fuel reprocessing plants. The system uses a maintenance-free jet injector to transport the waste resin.

[0048] like Figures 1-2As shown, the radioactive waste resin transfer system includes a transfer device A, a feeding unit B, and a discharging unit C. The transfer device A includes a tank truck shielded container 29, which receives waste resin from the feeding unit B and transfers it to the discharging unit C. The feeding unit B includes a first waste resin collection tank 17, a first ejector 21, and a first pump 27. The first waste resin collection tank 17 contains waste resin, which is drawn into the tank truck shielded container 29 by the first ejector 21. The first pump 27 provides first motive water to the first ejector 21. The first pump 27 in the feeding unit B provides first motive water to the first ejector 21. After the first ejector 21 forms a negative pressure, it draws and transports the waste resin from the first waste resin collection tank 17 into the tank truck shielded container 29. This invention uses a purely mechanical ejector structure, achieving maintenance-free resin transport.

[0049] To compensate for the low resin transfer efficiency of the ejector and the large amount of wastewater generated by the ejector's suction function, a water storage tank is installed in feed unit B to recycle the motive water. For example... Figure 1 As shown, the feeding unit B includes a first water storage tank 19. The first motive water originates from the first water storage tank 19 and is returned to the first water storage tank 19 after use. By setting up the first water storage tank 19, the problem of a large amount of wastewater generated during the jet ejector's suction function is solved, as the conveying efficiency gradually decreases with increasing height difference. The first water storage tank 19 significantly reduces the wastewater volume and enables the reuse of motive water, thus meeting the requirement of using jet ejectors to convey radioactive waste resin in spent fuel reprocessing facilities.

[0050] The transfer device A also includes a second ejector 10. A first pump 27 provides a second motive force water to the second ejector 10, which originates from a first water storage tank 19. After passing through the tank truck shielding container 29, the second motive force water is pumped and transported to the first water storage tank 19. The first pump 27 can be a centrifugal pump or other types of pumps. The centrifugal pump in the feeding unit B provides motive force water to the ejector inside the tank truck. The ejector creates a negative pressure, which, in conjunction with the filter 6 inside the tank truck shielding container 29, pumps the water inside the tank truck shielding container 29 and transports it to the water storage tank of the feeding unit B.

[0051] The transfer system includes a first pipe 11 and a second pipe 12. The feeding unit B and the transfer device A are connected via the first pipe 11 and the second pipe 12, which are flexible metal hoses. The transfer system also includes a third pipe and a fourth pipe. The third pipe is connected to deionized water D; the fourth pipe is connected to compressed air E. Additionally, the transfer device A includes a fifth pipe for conveying waste resin, and the feeding device includes a sixth pipe for conveying waste resin. After the waste resin loading rate meets the requirements, deionized water D and compressed air E are used to clean and purge any one or more of the first pipe 11, second pipe 12, fifth pipe, and sixth pipe. At this point, the waste resin loading process is complete. The tanker shielded container 29, loaded with a certain quantity of radioactive waste resin, travels to the unloading unit C.

[0052] The tanker truck shielded container 29 carrying waste resin travels to the plant where the waste resin unloading unit C is located. After connecting with the waste resin unloading unit C through the first pipe 11 and the second pipe 12, the waste resin unloading process begins.

[0053] The unloading unit C includes a second pump 38 and a second waste resin collection tank 37. The second pump 38 is a screw pump or other type of pump. The screw pump in the unloading unit C fills the tank truck shielding container 29 with water to increase the flowability of the waste resin. The second pump 38 provides third-stage motive water to the second ejector 10, through which the waste resin is transported to the second waste resin collection tank 37. The negative pressure created by the second ejector 10 draws the waste resin from the tank truck shielding container 29 and transports it to the second waste resin collection tank 37 of the unloading unit C.

[0054] In order to realize the recycling of power water, the unloading unit C also includes a second water storage tank 36. The second water storage tank 36 provides third power water. After passing through the tank truck shielding container 29, the third power water is pumped and transported to the second water storage tank 36.

[0055] The unloading device includes a seventh pipe for conveying waste resin. After the amount of waste resin residue in the shielded container meets the requirements, deionized water D and compressed air E are used to clean and purge any one or more pipes among the first pipe 11, the second pipe 12, the fifth pipe, and the seventh pipe. At this point, the waste resin unloading process ends.

[0056] The transfer system includes multiple valves, which enable the opening and closing of any one or more of the following pipelines: the first pipeline 11, the second pipeline 12, the third pipeline, the fourth pipeline, the fifth pipeline, the sixth pipeline, and the seventh pipeline.

[0057] The waste resin transfer system of this invention utilizes an ejector as the power source for waste resin transfer, taking into account the layout characteristics of spent fuel reprocessing plants. The ejector is characterized by its simple structure and maintenance-free operation, making it suitable for use in equipment rooms inaccessible to personnel. The waste resin transfer system employs a purely mechanical structure, such as the ejector, thus eliminating the need for maintenance in the resin transport system.

[0058] Meanwhile, by designing and installing water storage tanks and related pipeline valves, the kinetic water used in the loading and unloading processes of waste resin is recycled, thereby effectively reducing the amount of radioactive wastewater generated in the process. The waste resin transfer system of this invention includes the following steps:

[0059] Feeding unit B docking step S1: Connect feeding unit B to transfer device A;

[0060] Centrifugal pump start-up step S2: Fill the centrifugal pump with water and supply the first power water to the first ejector 21;

[0061] First resin transfer step S3: Transfer the waste resin from the first waste resin collection tank 17 to the tank truck shielded container 29 in the transfer device A;

[0062] Power water recovery step S4: Provide second power water to the second jet injector 10, and transport the first power water and the second power water to the first water storage tank 19 through the second jet injector 10;

[0063] Loading quantity judgment step S5: Check whether the resin loading quantity in the tank truck shield container 29 meets the requirements. If it does not meet the requirements, repeat the first resin transfer step S3 and the kinetic water recovery step S4.

[0064] Feed pipe cleaning S6: Rinse any one or more of the first pipe 11, second pipe 12, fifth pipe, and sixth pipe with deionized water D;

[0065] First purging step S7: Use compressed air E to purge any one or more of the first pipe 11, the second pipe 12, the third pipe, and the fourth pipe;

[0066] Unloading start-up step S8: Connect the tank truck shielding container 29 to the unloading unit C;

[0067] Unloading and water filling step S9: Fill the tank truck shielding container 29 with water to enhance the flowability of waste resin;

[0068] Second resin transfer step S10: Transfer the waste resin in the tank truck shielded container 29 to the second waste resin collection tank 37;

[0069] Residual amount judgment step S11: Check whether the residual amount of waste resin in the tank truck shield container 29 meets the requirements. If it does not meet the requirements, repeat the unloading and filling water step S9 and the second resin transfer step S10.

[0070] Unloading pipe cleaning step S12: Rinse any one or more pipes from the first pipe 11, the second pipe 12, the fifth pipe, and the seventh pipe with deionized water D;

[0071] Second purging step S13: Use compressed air E to purge any one or more of the first pipe 11, the second pipe 12, the fifth pipe, and the seventh pipe.

[0072] The specific operating procedures are as follows: Figures 1-3 As shown, the waste resin transfer tanker connects to the waste resin feeding unit B via the first pipe 11 and the first pipe 12. Then, valves 17 (26), 16 (25), 12 (20), 14 (23), 18 (28), 4 (7), 1 (3), 9 (15), and 10 (16) are opened. After the centrifugal pump is filled with water, it is started. Valve 15 (24) is opened, and the resin in the first waste resin collection tank 17 is transported to the tanker's shielded container 29 via the first ejector 21. When the level gauge 2 displays the set value, valve 15 (24) is closed first, then the centrifugal pump is stopped, and finally all other valves are closed. Then, dewatering is performed. Valve 17 (26), 13 (22), 18 (28), 6 (9), 3 (5), 9 (15), 11 (18), and 5 (8) are opened. After the centrifugal pump is filled with water, it is started. Valve 15 (24) and 16 (25) are opened to pump water from the first water storage tank to the second ejector 10. The second ejector 10 is used to pump water from the tanker truck's shielded container 29, and the pumped water is returned to the first waste resin collection tank 17. Once the level gauge 2 reading stabilizes, first close the fifteenth valve 24, then turn off the centrifugal pump, and finally close all other valves. The level gauge 2 is used to check whether the resin loading in the tanker truck's shielded container 29 meets the requirements.

[0073] If the requirements are not met, refill the resin and remove water until the requirements are met. Then, clean the pipeline by opening valves 13 (seventh), 9 (sixth), 15 (ninth), and 16 (tenth) to introduce deionized water (D) to flush the first pipeline (11) and the second pipeline (12), and drain the flushing water into the first waste resin collection tank (17). After flushing, close all valves. Finally, purge with compressed air (E) by opening valves 14 (eighth), 9 (sixth), 15 (ninth), and 16 (tenth) to purge and empty the pipeline. After purging, close all valves. This completes the resin loading process.

[0074] A transfer tanker truck carrying a certain amount of radioactive waste resin drove to the unloading unit C plant.

[0075] After the waste resin tanker shielded container 29 is connected to the waste resin unloading unit C through the first pipe 11 and the second pipe 12, the waste resin unloading process begins. Before unloading, water needs to be filled into the tanker shielded container 29 to enhance resin flowability. The 24th valve 35, 25th valve 39, 19th valve 30, 4th valve 7, 1st valve 3, 22nd valve 33, and 23rd valve 34 are opened, and the screw pump is started to fill the tanker shielded container 29 with water from the second water storage tank 36. When the high-level switch 1 is triggered, the screw pump is turned off, and all valves are closed. Then, the 24th valve 35, 25th valve 39, 2nd valve 4, 6th valve 9, 22nd valve 33, and 23rd valve 34 are opened, and the screw pump is started to pump water from the second water storage tank 36 to the inlet of the second ejector 10. The pressurized water creates a partial vacuum inside the ejector, sucking up the waste resin from the tanker shielded container 29 and transporting it to the second waste resin collection tank 37 of the unloading unit C. After unloading, shut off the screw pump and then close all valves. If there is a large amount of residual waste resin in the tank truck shielding container 29, continue to fill the tank truck shielding container 29 with water and then unload again. Continue until the remaining amount meets the requirements. Then, perform pipeline cleaning by opening valves 31 (20th), 9 (6th), 33 (22nd), and 34 (23rd) to introduce deionized water D from the plant for pipeline flushing. After flushing, close all valves. Finally, perform compressed air purging by opening valves 32 (21st), 9 (6th), 33 (22nd), and 34 (23rd) to introduce compressed air E from the plant for pipeline purging. After purging, close all valves. The waste resin unloading process is now complete.

[0076] This invention solves the problems of low resin transfer efficiency and large wastewater volume generated by ejectors by setting up a water storage tank and combining it with the corresponding process flow, so that the power water can be recycled.

[0077] In summary, it can be seen from the above description that the embodiments of the present invention achieve the following technical effects:

[0078] 1. The waste resin transfer system of this invention, based on the layout characteristics of spent fuel reprocessing plants, uses an ejector as the power equipment for waste resin transfer. The ejector is characterized by its simple structure and maintenance-free operation, making it suitable for use in equipment rooms inaccessible to personnel for maintenance. The waste resin transfer system adopts a purely mechanical structure such as an ejector, making the resin conveying system maintenance-free.

[0079] 2. By setting up water storage tanks and related pipeline valves, the kinetic water for the loading and unloading of waste resin is recycled, thereby effectively reducing the amount of radioactive wastewater generated in the process.

[0080] 3. Deionized water (D) and compressed air (E) were used to clean and purge the pipelines, ensuring their cleanliness.
