[0002] The high-temperature gas-cooled reactor fuel handling system performs the function of replacing fuel without stopping the reactor, which is a key system for ensuring the long-term safe and stable operation of the high-temperature gas-cooled reactor. The high-temperature gas-cooled reactor uses fuel balls with graphite as the base body. After use, the fuel balls need to be distributed using a distribution resistance device, so as to distribute the enriched fuel balls for continued use and distribute the spent fuel balls for disposal. However, the distribution efficiency of the distribution resistance device in the related art is low, which affects the overall operation efficiency of the high-temperature gas-cooled reactor.

[0003] The inventor found that the fuel balls take a long time to measure the burnup in the burnup measurement device of the distribution resistance device. However, the distribution resistance device in the related art can only accommodate one fuel ball for burnup measurement at a time, resulting in low distribution efficiency of the distribution resistance device for multiple fuel balls.

[0031] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0032] A dispensing positioning device 100 according to an embodiment of the present application is described below with reference to the drawings.

[0033] As Figures 1-8 shown, the distribution positioning device 100 of the embodiment of the present application comprises a housing 1, a first rotor 2 and a second rotor 3.

[0034] The housing 1 defines a detection chamber 101 and a distribution chamber 102, which are opposite in the axial direction of the housing 1. The housing 1 further comprises a plurality of feeding ports 121, each of which is in communication with the detection chamber 101, and a first discharging port 131 and a second discharging port 132, which are both in communication with the distribution chamber 102.

[0035] The first rotor 2 comprises a plurality of feeding through holes 2111 for accommodating fuel balls, which are spaced apart in the circumferential direction of the first rotor 2. The first rotor 2 is rotatably arranged in the detection chamber 101 about the axis of the housing 1, so that the plurality of feeding through holes 2111 can be in one-to-one correspondence with the plurality of feeding ports 121. In other words, the first rotor 2 rotates about the axial direction of the housing 1, when the feeding through hole 2111 of the first rotor 2 rotates to a position corresponding to the feeding port 121, the feeding through hole 2111 is in communication with the feeding port 121, and the fuel balls from the outside can enter the feeding through hole 2111 through the feeding port 121; when the feeding through hole 2111 of the first rotor 2 rotates to a position offset from the feeding port 121, the feeding through hole 2111 is not in communication with the feeding port 121, and the fuel balls from the outside are blocked by the housing 1 and cannot enter the feeding through hole 2111.

[0036] The second rotor 3 comprises a discharging passage 30, and the first rotor 2 is rotatably arranged in the distribution chamber 102 about the axial direction of the housing 1, so that one of the plurality of feeding through holes 2111 can be in communication with one of the first discharging port 131 and the second discharging port 132 through the discharging passage 30. In other words, the first rotor 2 can rotate relative to the second rotor 3, the discharging passage 30 rotates to a position corresponding to the feeding through hole 2111, the discharging passage 30 is in communication with the feeding through hole 2111, and the fuel balls in the feeding through hole 2111 can enter the discharging passage 30. The rotation of the second rotor 3 makes the discharging passage 30 communicate with one of the first discharging port 131 and the second discharging port 132, so that the fuel balls are discharged from the one of the first discharging port 131 and the second discharging port 132. Alternatively, the second rotor 3 can rotate about the axial direction of the housing 1 relative to the first rotor 2, and the discharging passage 30 can directly communicate the feeding through hole 2111 and one of the first discharging port 131 and the second discharging port 132, so that the fuel balls are discharged from the one of the first discharging port 131 and the second discharging port 132. Among them, the first discharging port 131 is used to discharge the spent fuel balls, and the second discharging port 132 is used to discharge the enriched fuel balls.

[0037] The specific implementation process of the distribution positioning device 100 of the embodiment of the present application is described below with reference to the accompanying drawings.

[0038] The first rotor 2 rotates, and the plurality of feeding ports 121 are in communication with the plurality of feeding through holes 2111 one by one, so that the plurality of fuel balls from the outside fall into the plurality of feeding through holes 2111 respectively. After the plurality of fuel balls enter the plurality of feeding through holes 2111 one by one, the first rotor 2 rotates again to misalign the plurality of feeding ports 121 and the plurality of feeding through holes 2111, so that the fuel balls from the outside cannot enter the shell 1. The plurality of fuel balls entering the plurality of feeding through holes 2111 respectively are detected by the external burnup measuring device respectively, so as to distribute the spent fuel balls and the enriched fuel balls. After the detection is completed, the first rotor 2 and the second rotor 3 rotate relatively, so that the fuel balls in one feeding through hole 2111 are in communication with one of the first discharge port 131 and the second discharge port 132 through the discharge channel 30, so as to discharge the fuel balls from the one of the first discharge port 131 and the second discharge port 132. After the fuel balls are discharged, the first rotor 2 and the second rotor 3 rotate relatively again, so that the fuel balls in another feeding through hole 2111 are in communication with one of the first discharge port 131 and the second discharge port 132 through the discharge channel 30, so as to discharge the fuel balls from the one of the first discharge port 131 and the second discharge port 132. The above operation is repeated until the fuel balls in the plurality of feeding through holes 2111 are all discharged from the shell 1.

[0039] The distribution positioning device 100 of the embodiment of the present application simultaneously performs burnup detection on the plurality of fuel balls in the plurality of feeding through holes 2111 by arranging the plurality of feeding through holes 2111 capable of accommodating fuel balls on the first rotor 2. Then, the relative rotation of the first rotor 2 and the second rotor 3 enables the fuel balls of different types (i.e., spent fuel balls and enriched fuel balls) in the plurality of feeding through holes 2111 to be discharged from the first discharge port 131 or the second discharge port 132 one by one through the discharge channel 30, so as to realize the detection and distribution operation of the fuel balls. Compared with the related art, the distribution positioning device 100 of the embodiment of the present application can simultaneously perform burnup detection on the plurality of fuel balls, thereby reducing the burnup detection time of the plurality of fuel balls. Therefore, the distribution positioning device 100 of the embodiment of the present application improves the distribution efficiency of the fuel balls.

[0040] Therefore, the distribution positioning device 100 of the embodiment of the present application has the advantage of high distribution efficiency.

[0041] In order to make the present application easier to be understood, the axial direction of the surrounding wall 11 is taken as an example, and the distribution positioning device 100 of the embodiment of the present application is further described below.

[0042] As Figures 1-8As shown, the shell 1 comprises a surrounding wall 11, a partition plate 14, a first end cover 12 and a second end cover 13, the surrounding wall 11 comprises a first end and a second end opposite in the up-down direction, wherein the first end is the upper end and the second end is the lower end. The first end cover 12 is connected with the first end, the second end cover 13 is connected with the second end, and the partition plate 14 is connected with the inner wall surface of the surrounding wall 11. The first end cover 12, the surrounding wall 11 and the partition plate 14 define a detection chamber 101, and the first rotor 2 is rotatably arranged in the detection chamber 101 around the axial direction of the surrounding wall 11. The second end cover 13, the surrounding wall 11 and the partition plate 14 define a distribution chamber 102, and the second rotor 3 is rotatably arranged in the distribution chamber 102 around the axial direction of the surrounding wall 11. The partition plate 14 is provided with a discharging channel 141, and the feeding through hole 2111 and the discharging channel 30 can communicate through the discharging channel 141.

[0043] After the fuel balls in the plurality of feeding through holes 2111 are detected, the plurality of feeding through holes 2111 are rotated to a position communicated with the discharging channel 141, so that the fuel balls are first discharged into the discharging channel 141, thereby emptying the feeding through hole 2111. The second rotor 3 is rotated to make the discharging channel 141 communicated with one of the first discharging port 131 and the second discharging port 132 through the discharging channel 30, so that the fuel balls are discharged from the one of the first discharging port 131 and the second discharging port 132, and the distribution of the fuel balls is completed. In the process of distributing the fuel balls, the corresponding feeding through hole 2111 of the fuel balls can be communicated with the feeding port 121 again, so that the fuel balls outside can enter the feeding through hole 2111 for burnup detection, and the distribution operation of the fuel balls being distributed is not affected, thereby further improving the distribution efficiency of the distribution positioning device 100.

[0044] Further, the discharging channel 141 is a plurality of discharging channels 141, and the plurality of discharging channels 141 are spaced apart in the circumferential direction of the surrounding wall 11. In other words, after the plurality of fuel balls are detected, all the fuel balls are discharged into the corresponding plurality of discharging channels 141, and then the second rotor 3 is rotated to distribute the fuel balls one by one in the plurality of discharging channels 141. In the process of distributing the plurality of fuel balls, the plurality of feeding through holes 2111 can be entered by the plurality of fuel balls for burnup detection again, thereby further improving the distribution efficiency of the distribution positioning device 100.

[0045] In some embodiments, the dispensing positioning device 100 of the present embodiments further comprises a first rotating shaft and a second rotating shaft, the first end cover 12 is provided with a first shaft hole, one end of the first rotating shaft is connected with the first rotor 2 through the first shaft hole, and the other end of the first rotating shaft is connected with a first driving device, for example, the first driving device is an electric motor. The second end cover 13 is provided with a second shaft hole, one end of the second rotating shaft is connected with the second rotor 3 through the second shaft hole, and the other end of the second rotating shaft is connected with a second driving device, for example, the second driving device is an electric motor.

[0046] In some embodiments, as shown in Figure 1 and Figure 5 , the first rotor 2 comprises a first rotating disc 21 and a plurality of ball pushing plates 22, the first rotating disc 21 is rotatably arranged in the detection chamber 101 around the axial direction of the surrounding wall 11, the outer edge of the first rotating disc 21 comprises a plurality of protrusions 211, the plurality of protrusions 211 are spaced apart in the circumferential direction of the surrounding wall 11, and adjacent protrusions 211 and the surrounding wall 11 define a feeding through hole 2111. The plurality of ball pushing plates 22 are arranged one by one on the plurality of protrusions 211. In other words, the ball pushing plates 22 are arranged at positions corresponding to the feeding through holes 2111 on the first rotating disc 21, and the ball pushing plates 22 can provide better support for the fuel balls during the rotation of the first rotor 2, so that the first rotor 2 can move the fuel balls more sensitively.

[0047] In some embodiments, as shown in Figure 2 , the shell 1 further comprises a baffle 15, the baffle 15 is connected with the inner wall of the detection chamber 101, and the baffle 15 is located between the first rotor 2 and the partition plate 14. The baffle 15 is provided with a plurality of ball falling holes, the ball falling holes are spaced apart in the circumferential direction of the surrounding wall 11, and the plurality of ball falling holes and the plurality of ball falling channels 141 are in one-to-one correspondence. The baffle 15 is also provided with a plurality of chip removal holes 153, and the chip removal holes 153 correspond to the plurality of feeding through holes 2111 in the inner-outer direction.

[0048] In other words, the baffle 15 is arranged between the partition plate 14 and the first rotor 2, so that the fuel balls receive support from the baffle 15 after entering the detection chamber 101. And the baffle 15 is provided with a plurality of chip removal holes 153, so that the broken balls and chippings can fall from the baffle 15 through the chip removal holes 153 when the first rotor 2 pushes the fuel balls to rotate, thereby avoiding the broken balls and chippings from blocking the first rotor 2 and causing the first rotor 2 to jam. Therefore, the sensitivity of the dispensing positioning device 100 of the present embodiments is improved.

[0049] In addition, the baffle 15 is provided with a plurality of ball falling holes corresponding to the ball falling channels 141, so that the baffle 15 will not affect the fuel balls after detection from entering the ball falling channels 141.

[0050] In some embodiments, as shown in Figure 6 andFigure 7 As shown, the baffle 15 further comprises an inner baffle 151 and an outer baffle 152, both of which are arranged in the detection chamber 101 and opposite to each other in the inner-outer direction. The outer edge of the inner baffle 151 is provided with a plurality of first notches 1511 which are spaced apart in the circumferential direction of the enclosing wall 11. The outer edge of the outer baffle 152 is provided with a plurality of second notches 1521 which are spaced apart in the circumferential direction of the enclosing wall 11, and the plurality of first notches 1511 and the plurality of second notches 1521 correspond to each other in the inner-outer direction. Adjacent first notches 1511 and second notches 1521 form a falling ball hole, and the outer edge of the inner baffle 151 and the inner edge of the outer baffle 152 have a gap therebetween, which forms a chip removal hole 153. In other words, the annular gap is formed between the inner baffle 151 and the outer baffle 152, so that the first rotating path has a discharge port for allowing the broken balls and chips to fall, thereby further improving the chip removal capability, and the rotation of the first rotor 2 is not blocked by the broken balls and chips, thereby further improving the sensitivity of the dispensing positioning device 100 of the embodiment of the present application.

[0051] In some embodiments, as shown in Figure 5 As shown, a plurality of ball pushing plates 22 are arranged on the first rotating disc 21 adjacent to one side of the partition plate 14, and one end of the ball pushing plate 22 is connected to the first rotating disc 21, and the other end of the ball pushing plate 22 is inserted into the gap. When the chips and broken balls accumulate on the gap, they are not easy to fall off. By using the ball pushing plate 22 to cut the chip pile when moving, the chips and broken balls are easy to fall off through the gap, thereby improving the chip removal capability and avoiding the dispensing positioning device 100 of the embodiment of the present application from blocking the balls when dispensing the fuel balls, thereby ensuring the dispensing efficiency of the fuel balls.

[0052] Further, as shown in Figure 5As shown, each push ball plate 22 includes a first section 221, a second section 222 and a third section 223, one of the first section 221 and the second section 222 is used to push the fuel ball when the first rotor 2 rotates. The first section 221 and the third section 223 are spaced apart in the circumferential direction, and the first section 221 is adjacent to one of the feed-through holes 2111, the third section 223 is adjacent to another of the feed-through holes 2111 adjacent to the one of the feed-through holes 2111, and the second section 222 is located between the first section 221 and the third section 223. The size of the first section 221 in the inner-outer direction decreases in the direction away from the third section 223, and the size of the third section 223 in the inner-outer direction decreases in the direction away from the first section 221. In other words, the first section 221 and the third section 223 are both sharp ends adjacent to one end of the feed-through holes 2111, so that one of the first section 221 and the third section 223 can better push the debris and broken balls in its moving path into the chip removal hole 153 in the process of pushing the fuel ball, avoiding the influence of the debris and broken balls on the rotation of the first rotor 2.

[0053] In some embodiments, as shown in Figure 1 and Figure 8 As shown, the second rotor 3 includes a second rotating disc 31 and a third rotating disc 32, the second rotating disc 31 and the third rotating disc 32 are opposite in the circumferential direction of the enclosing wall 11, the second rotating disc 31 includes a first ball inlet hole 311 and a second ball inlet hole 312, the first ball inlet hole 311 and the second ball inlet hole 312 are spaced apart in the circumferential direction of the enclosing wall 11, the second rotating disc 31 includes a first ball outlet hole 321 and a second ball outlet hole 322, the first ball outlet hole 321 and the second ball outlet hole 322 are spaced apart in the circumferential direction of the enclosing wall 11. A first discharge pipe 33 and a second discharge pipe 34, one end of the first discharge pipe 33 communicates with the first ball inlet hole 311, the other end of the first discharge passage 30 communicates with the first ball outlet hole 321, one end of the second discharge pipe 34 communicates with the second ball inlet hole 312, the other end of the second discharge passage 30 communicates with the second ball outlet hole 322. In other words, the first discharge pipe 33 and the second discharge pipe 34 form a discharge passage 30.

[0054] When the fuel balls in the discharge channel 141 are spent fuel balls, the second rotor 3 rotates, connecting the first inlet hole 311 to the discharge channel 141 and the first outlet hole 321 to the first outlet port 131. The spent fuel balls in the discharge channel 141 enter the first outlet pipe 33 through the first inlet hole 311 and are discharged through the first outlet hole 321 and the first outlet port 131. When the fuel balls in the discharge channel 141 are enriched fuel balls, the second rotor 3 rotates, connecting the second inlet hole 312 to the discharge channel 141 and the second outlet hole 322 to the second outlet port 132. The enriched fuel balls in the discharge channel 141 enter the second outlet pipe 34 through the second inlet hole 312 and are discharged through the second outlet hole 322 and the second outlet port 132. The rotation of the second rotor 3 controls the first discharge pipe 33 to connect the discharge channel 141 and the first discharge port 131, or the second discharge pipe 34 to connect the discharge channel 141 and the second discharge port 132, so that spent fuel balls or enriched fuel balls are discharged from the corresponding first discharge port 131 or second discharge pipe 34, thereby completing the distribution operation. Therefore, the structure is simple and the operation is convenient.

[0055] In some embodiments, such as Figure 8 As shown, the first discharge pipe 33 is inclined, and the first inlet hole 311 and the first outlet are spaced apart circumferentially in the enclosure wall 11. The second discharge pipe 34 is also inclined, and the second inlet hole 312 and the second outlet are spaced apart circumferentially in the enclosure wall 11. In other words, both the first discharge pipe 33 and the second discharge pipe 34 are inclined. When the fuel balls in the discharge channel 141 fall into one of the first discharge pipe 33 and the second discharge pipe 34, that pipe can slow down the falling speed of the fuel balls and prevent them from being damaged.

[0056] In some embodiments, such as Figure 8 As shown, there are multiple first ball inlet holes 311 and multiple second ball inlet holes 312. The multiple first ball inlet holes 311 are spaced apart circumferentially on the second turntable 31, and the multiple second ball inlet holes 312 are spaced apart circumferentially on the second turntable 31, with the multiple first ball inlet holes 311 and multiple second ball inlet holes 312 being staggered circumferentially on the second turntable 31. There are also multiple first ball outlet holes 321 and multiple second ball outlet holes 322. The multiple first ball outlet holes 321 are spaced apart circumferentially on the third turntable 32, and the multiple first ball outlet holes 321 and multiple second ball outlet holes 322 are spaced apart circumferentially on the third turntable 32, with the multiple first ball outlet holes 321 and multiple second ball outlet holes 322 being staggered circumferentially on the third turntable 32.

[0057] The first discharge pipes 33 are a plurality of first discharge holes 321 and a plurality of first discharge holes 311 one-to-one correspondence, a plurality of first discharge pipe 33 in the circumferential direction of the wall 11 will be separated, and a plurality of first discharge pipe 33 one-to-one correspondence of the first discharge hole 321 and the first discharge hole 311 is communicated. The second discharge pipe 34 is a plurality of second discharge holes 312 and a plurality of second discharge holes 322 one-to-one correspondence, a plurality of second discharge pipe 34 in the circumferential direction of the wall 11 will be separated, and a plurality of second discharge pipe 34 one-to-one correspondence of the second discharge hole 312 and the second discharge hole 322 is communicated.
