Description

Technical Field

[0001] The invention relates to the technical field of radiation shielding, and in particular to a highly sealed shielding automated sample introduction system for a radioactive sample surface chemical morphology analysis test. Background Art

[0002] As advanced pressurized water reactors are put forward higher requirements in terms of safety, the influence of the chemical environment of irradiated water in the reactor on key structural materials has received more and more attention, especially the adverse effect on the integrity of zirconium alloy cladding (material). The environment in which the zirconium alloy cladding is in is extremely harsh when it is in service in the reactor. It not only needs to withstand the influence of high temperature and high pressure complex water chemical environment, but also is affected by α, β, γ irradiation and neutron irradiation. Under these conditions, the microstructure and chemical form of the zirconium alloy cladding material change, resulting in a decrease in its corrosion resistance, accelerated corrosion of the material, and then caused the failure of the material. Therefore, the study of the corrosion performance of zirconium alloy cladding materials in the harsh environment of nuclear reactors, especially the study of the influence of the chemical environment of irradiated water in the reactor on the surface chemical form of zirconium alloy materials, is of great significance to avoid or slow down the corrosion rate of zirconium alloy cladding materials and ensure the safety of reactors.

[0003] At present, the research on the influence of irradiated water chemical environment on the surface chemical morphology of zirconium alloy materials is mainly carried out by heavy ion irradiation or gamma irradiation simulating in-pile irradiation. However, the influence of irradiation and water chemical environment under actual working conditions in the reactor on material corrosion is far more complicated than the influence of a single irradiation condition on material corrosion. Therefore, the study on the influence of in-pile irradiated water chemical environment on the surface chemical morphology of zirconium alloy materials is a must for the study of the corrosion performance of zirconium alloy materials in the harsh environment of nuclear reactors. Since the corrosion samples after in-pile irradiation are extremely radioactive, in order to ensure the safety of analysts and the environment, it is necessary to carry out specific shielding modification according to the characteristics of the surface chemical morphology analysis equipment, and establish a matching analysis method according to the characteristics of the modified system structure to obtain accurate and stable test data. Therefore, it is necessary to design and manufacture a high-sealing shielded automatic sampling system for surface chemical morphology analysis experiments of radioactive samples according to the structural characteristics of the existing material surface chemical morphology analysis equipment - X-ray photoelectron spectrometer (hereinafter referred to as XPS) and the requirements for radioactive sample analysis, and establish a supporting analysis method to effectively complete the XPS surface chemical morphology analysis test of radioactive samples after irradiation in the in-pile water chemical environment, obtain the corrosion behavior law data of zirconium alloy cladding materials under the in-pile service conditions of high temperature, high pressure and strong radiation field, while ensuring the safety of personnel and the environment during the test.

[0004] Existing shielding devices, such as the X-ray radiation shielding building proposed in the patent with publication number CN105604353A, can effectively reduce the energy of X-rays through multiple shielding corners in pedestrian passages, and then use lead doors to attenuate the radiation energy to meet the standard. The quality of lead doors is strong and it is easy to open. There is no need to open the shielding door frequently, which saves time and effort. Multiple lead doors and shielding corners work together to achieve a good shielding effect. However, it is mainly aimed at X-ray flaw detection equipment used inside to prevent its radiation from being externalized, and its radiation source is weak and fixed.

[0005] There is also a radiation item shielding transfer system proposed in the patent with publication number CN116798672A, which can better avoid human involvement in the transfer process and improve safety. However, for the analysis of radioactive items, it is necessary to take them out of the shielding box and expose them, which still has the risk of radiation leakage. At present, there is no protective shielding sampling device for radioactive sample detection. Summary of the invention

[0016] Preferably, the detection system is provided with an instrument sampling port for receiving the pre-treated sample.

[0017] Preferably, it also includes a monitoring system for detecting sample transportation and sample preparation, and the monitoring system includes a camera arranged in the first shielding box.

[0018] A method for using a high-sealing shielded automated sampling system for a radioactive sample surface chemical morphology analysis test comprises the following steps:

[0019] S1: Place the sample in the sample basket of the shielding transport container and transfer it to the first shielding box via a transport trolley;

[0020] S2: transport the sample basket to the sample operation table to pre-treat the sample;

[0021] S3: The pretreated sample is sent to the instrument sampling port through the transmission track and detected by the detection system.

[0022] Preferably, it further comprises a lifting device and a lifting device. In the step S1, after the shielded transport container is lifted into the first shielded box by the lifting device, the shielded transport container is then transferred by the lifting device, and the sample basket in the shielded transport container is taken out through the glove operation hole. Preferably, in the step S1, after the shielded transport container is lifted into the first shielded box by the lifting device, the shielded transport container is then transferred by the lifting device, and the sample basket in the shielded transport container is taken out through the glove operation hole.

The whole system adopts a high-sealing design to prevent radioactive materials from leaking into the environment. The combination of the auxiliary transport transmission system and the control system realizes the automation of the whole process from storage, transportation to pretreatment and detection of samples, reduces manual intervention and improves work efficiency.

The circulation purification system and the air intake and exhaust filtration system ensure the cleanliness of the detection environment and reduce the influence of external factors on the test results. Negative pressure maintenance and control of dissolved oxygen content in the air help to provide a stable and suitable environment for detection, thereby ensuring the consistency and accuracy of the data. The design of the shielded transport container and the use of the transport trolley simplify the sample transfer process and reduce the risk of sample damage.

[0025] While effectively shielding the radiation of samples during the testing process, the system reduces the interference of the environment on the sample preparation and testing process. It ensures the cleanliness of the testing environment through the air inlet and exhaust filtration system and the circulating purification system, ensuring the consistency of the testing environment for batch testing, which is conducive to improving the accuracy and stability of the test.

[0045] Example 1

[0046] A highly sealed shielded automated sample loading system for a radioactive sample surface chemical morphology analysis test, comprising a first shielding box 1 for shielding radiation during sample transportation and detection, and a second shielding box 2 arranged outside the first shielding box 1 for shielding radiation during sample detection, wherein the first shielding box 1 is provided with an auxiliary transport system for transporting samples and a control system for controlling sample loading and detection outside the second shielding box 2;

[0047] The control system includes a pre-processing control system for pre-processing and preparing samples and a detection control system 3 for controlling the detection system 14 to detect the samples;

[0048] The auxiliary transport transmission system includes a shielded transport system for transporting samples to the first shielded box 1 and an auxiliary transport system for sending samples in and out of pretreatment.

[0049] In this embodiment, the second shielding box 2 includes a detection system 14 for detecting samples, a circulation purification system 15 for controlling the dissolved oxygen content of water in the air in the first shielding box 1, and an air inlet and exhaust filtration system for maintaining the negative pressure of the first shielding box 1 and filtering solid particles.

[0050] In this embodiment, the detection system 14 is an XPS analysis device.

[0051] In this embodiment, the first shielding box 1 has an internal space size of 1150×650×1000 (mm), and its lining is made of 3mm 304 stainless steel plate welded by argon arc welding, and is integrally embedded in the second shielding box 2; a sealed double-cover docking interface for docking with the transfer trolley 4 is reserved at the bottom, a sealed docking hatch is arranged on the rear side, and docking with the hatch of the injection pause room of the equipment (XPS), and two sets of single-station glove operation holes 12 are arranged at the corresponding positions on the front side, and the glove operation holes 12 are compressed and sealed with O-rings to ensure that the sealing of the first shielding box 1 reaches the nuclear secondary sealing (according to EJ / T 1096-1999 standard, the leakage rate is ≤2.5×10 -3 / h); the front sealing cover of the glove operation hole 12 is made of 110mm thick carbon steel, and the gloves used are lead-containing chloroprene rubber shielding gloves specially used for nuclear industry γ.

[0052] In this embodiment, the second shielding box 2 is welded as a whole with a 110mm carbon steel plate to achieve radioactive shielding of α rays and a small amount of β and γ rays; the observation window 21 is sealed with an O-ring, the inspection door is sealed with a sealing strip, and the through hole is sealed with a KF40 flange welding and an O-ring. The overall sealing reaches the nuclear level 3 sealing (according to EJ / T 1096-1999 standard, the leakage rate is ≤1×10 -2 / h).

[0053] In this embodiment, the air inlet and exhaust filtration system includes an exhaust valve 17 and an air inlet valve 20 respectively connected to the first shielding box 1. The exhaust valve 17 and the air inlet valve 20 are also provided with an inlet and outlet dry pump 16 for providing negative pressure, and a filter 18 and a special exhaust pipe 19 for filtering solid particles.

[0054] In this embodiment, the detection system 14 is provided with an instrument sample inlet 13 for receiving the pre-treated sample.

[0055] In this embodiment, a monitoring system for detecting the sample transfer and sample preparation conditions is also included, and the monitoring system includes a camera 10 disposed in the first shielding box 1 .

[0056] A method for using a high-sealing shielded automated sampling system for a radioactive sample surface chemical morphology analysis test comprises the following steps:

[0057] S1: placing the sample in the sample basket 6 of the shielding transport container 5 and transferring it to the first shielding box 1 via the transport trolley 4;

[0058] S2: transporting the sample basket 6 to the sample operation table 9 to pre-treat the sample;

[0059] S3: The pretreated sample is sent to the instrument sampling port 13 through the transmission track 8 and detected by the detection system 14 .

[0060] In this embodiment, in step S1, after the shielded transfer container 5 is lifted by the lifting device 41, the shielded transfer container 5 is lifted into the first shielding box 1 by the lifting device 41, and then the shielded transfer container 5 is transferred by the lifting device 7, and the sample basket 6 in the shielded transfer container 5 is taken out through the glove operation hole 12.

[0061] The specific operation method is that the analyst automatically pushes the automated transfer cart 4 from the hot chamber to the test site, manually operates the cart to find the position, and automatically opens the top plate after determining that it is at the docking position with the first shielding box 1. The shielding transfer container 5 is pressed and sealed with the docking hole at the bottom of the first shielding box 1 by the lifting device 41, and then the shielding transfer container sealing cover is lifted and transferred to the designated position by the automatic lifting device 7 in the first shielding box 1. Finally, the sample basket 6 containing the radioactive corrosion sample is pushed into the first shielding box 1 by the lifting device. Then, the lifting device 7 is operated by the operating control system to clamp the fixed basket 6 pushed into the first shielding box 1 and transfer it to the sample operation table 9 in the first shielding box 1 through the transmission track 8. The operator removes the sample in the sample basket 6 on the sample operation table 9 through the glove operation hole 12 and performs pretreatment before sample analysis. After the pretreatment, the sample is fixed on the XPS sample tray for standby use. Subsequently, the instrument inlet 13 door of the analysis equipment XPS14 built into the second shielding box 2 is opened; the instrument inlet 13 located at the rear side of the first shielding box 1, which is docked with the hatch of the pause room inlet, is opened. The operator manipulates the clamp through the glove operation hole 12 to send the XPS sample tray into the pause room through the instrument inlet 13, and finally closes the hatch of the pause room inlet, closes the docking hatch, and XPS14 automatically evacuates the sample tray. After the vacuum degree of the pause room is less than 1E-7mbar, the sample tray is transferred to the analysis room inside the analysis equipment XPS, and after the vacuum degree of the analysis room is less than 5E-9mbar, it is prepared for further analysis. During the above process, the first shielding box 1 and the second shielding box 2 are always maintained in a negative pressure state, and the radioactive waste gas generated in the process is filtered by the nuclear grade filter 18 and enters the special exhaust duct 19.

[0062] The analysis method was established through the XPS operating software Avantage and then the analysis program was executed to obtain the chemical morphology spectrum of the surface of the zirconium alloy after corrosion. It can be seen that the main components of the surface of the zirconium alloy after corrosion are C, O, and Zr, among which Zr mainly exists in the form of ZrO and ZrO2, with relative contents of 0.66% and 4.73% respectively.

[0063] Working principle and usage;

[0064] By adopting this technical solution, by setting the first shielding box 1 and the second shielding box 2, the radiation of the radioactive sample during the transportation and detection process is effectively isolated, and the operator is protected from radiation damage. The whole system adopts a high-sealing design to prevent radioactive substances from leaking into the environment. The combination of the auxiliary transport transmission system and the control system realizes the automation of the whole process from storage, transportation to pretreatment and detection of samples, reduces manual intervention and improves work efficiency. Through the design of the glove operation hole 12 and the observation window 21, the operator can handle and detect the sample in a safe environment without direct contact with the radioactive material. The circulation purification system 15 and the air intake and exhaust filtration system ensure the cleanliness of the detection environment and reduce the influence of external factors on the test results. Negative pressure maintenance and control of dissolved oxygen content in the air help to provide a stable and suitable environment for detection, thereby ensuring the consistency and accuracy of the data. The design of the shielded transport container 5 and the use of the transport trolley 4 simplify the sample transfer process and reduce the risk of sample damage. The system integrates multiple functional modules such as sample pretreatment, transfer, and detection, making the entire analysis process smoother and more compact. The setting of the camera 10 allows the operator to monitor the sample transfer and sample preparation in real time, so as to find and solve problems in time.
