Description

Technical Field

[0001] This invention relates to the field of radiation monitoring technology for nuclear facilities, and in particular to an online monitoring device for multiple nuclides in gaseous effluents based on modular integration. Background Technology

[0002] Nuclear facilities, especially nuclear power plants, continuously release gaseous effluents containing trace amounts of radionuclides into the environment during normal operation. Rigorous and precise monitoring of these gaseous effluents is crucial for assessing the environmental impact of nuclear facility operations and ensuring public health and safety. Key radionuclides requiring monitoring in gaseous effluents include tritium (H-3), carbon-14 (C-14), radioactive iodine, aerosols, and various radioactive inert gases (such as Ar-41, Kr-85, and Xe-133). Currently, monitoring of gaseous effluents primarily relies on two technical approaches: offline laboratory analysis and on-site radiation monitoring systems. Offline laboratory analysis involves periodically collecting gas samples and sending them to a laboratory for complex processes including chemical separation, sample preparation, and analysis using analytical instruments to measure radionuclide activity. On-site radiation monitoring systems, through the KRT continuous monitoring system, are used to monitor the gamma dose rate or total radioactivity level of gaseous effluents from chimneys in real time. However, both of these technical approaches have significant systemic drawbacks. Laboratory analysis relies on sampling and laboratory analysis, which is time-consuming and complex. On-site monitoring can only achieve gamma dose rate or total radioactivity analysis, but cannot quantify radionuclides. Currently, there is no integrated system or equipment capable of simultaneous, fully automated, and online monitoring of multiple radionuclides in gaseous effluents from nuclear power plants and other nuclear facilities. Summary of the Invention

[0020] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention.

In other embodiments, well-known mechanisms and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0021] This invention provides a modularly integrated online monitoring device for multiple nuclides in gaseous effluents. The monitoring device adopts a modular integrated design structure, integrating complex fluid control, sample processing, and sample measurement modules into the same cabinet, thereby reducing the equipment footprint and realizing system integration and space compactness for multi-nucleon monitoring. This improves the technical problems of low monitoring efficiency and difficulty in achieving simultaneous multi-nucleon monitoring in existing nuclear facility gaseous effluent monitoring technologies.

[0022] Please see Figures 1 to 5 This invention provides a modularly integrated online monitoring device for multiple nuclides in gaseous effluents. The device includes a cabinet 100, an aerosol and iodine monitoring module 200, a tritium and carbon-14 monitoring module 300, an inert gas β monitoring module 400, and an inert gas γ nuclide monitoring module 500. The cabinet 100 serves as the integrated physical carrier of the monitoring device, housing and protecting the various monitoring modules. The cabinet 100 can be a rectangular, square, or cylindrical structure of any shape. Specifically, in this embodiment, the cabinet 100 is a standard industrial cabinet structure, integrating the monitoring modules within it to reduce the device's footprint, lower system complexity, and ensure long-term operational reliability in the harsh environment of the nuclear industry. The cabinet 100's outer shell is made of 304 stainless steel and undergoes anti-corrosion treatment, such as spraying anti-corrosion paint. The interior of the cabinet 100 can be divided into three main integration areas along the length of the cabinet 100 according to the installation and integration requirements of functional modules: the first integration area 110, the second integration area 120, and the third integration area 130. Each integration area has at least one cabinet door on the side wall of the cabinet 100. Multiple cabinet doors can also be set according to functional needs. The structure design of multiple cabinet doors allows operators to open only the cabinet door corresponding to the target area for operation, improving maintenance efficiency and maintenance convenience.

[0023] The aerosol and iodine monitoring module 200 is an independent unit integrating sampling, filtering, and detection functions. It is used to continuously collect and measure radioactive aerosols (such as Cs-137 and Co-60) and radioactive iodine (such as I-131) in gaseous effluents in real time. The aerosol and iodine monitoring module 200 is integrated and installed in the first integration area 110. The aerosol and iodine monitoring module 200 includes an aerosol and iodine treatment module 210, an aerosol detection module 220, and an iodine detection module 230. The aerosol and iodine treatment module 210 is connected to both the aerosol detection module 220 and the iodine detection module 230. Specifically, the aerosol and iodine treatment module 210 includes an automatic paper-feeding filter device and an activated carbon adsorption box. The automatic paper-feeding filter device continuously captures aerosol particles using filter paper and is coupled to the aerosol detection module 220. The aerosol detection module 220 employs a high-resolution cadmium zinc telluride (CZT) detector to perform gamma-ray spectrometry analysis on aerosol samples on filter paper in the automatic paper feeding filter device, enabling the identification and activity measurement of nuclides such as Cs-137 and Co-60. An activated carbon adsorption box is used to adsorb gaseous radioactive iodine and is coupled to the iodine detection module 230, which uses a lanthanum bromide (LaBr3) detector to measure the iodine isotopes (such as I-131) adsorbed by the activated carbon box. The aerosol and iodine treatment module 210 also includes a gas pump and a flow path switching valve, which can control the gas effluent to flow separately or simultaneously to the aerosol trapping channel, the iodine adsorption channel, or other detection channels according to measurement requirements.

[0024] The tritium and carbon-14 monitoring module 300 is located in the second integrated area 120 and is used for the fully automated conversion and measurement of samples from gaseous to measurable liquid states, facilitating the detection of tritium (H⁻³) and carbon-14 (C⁻¹⁴), which are difficult to measure directly. The tritium and carbon-14 monitoring module 300 includes a tritium and carbon-14 sample processing module 310, a tritium detection module 320, and a carbon-14 detection module 330. The tritium and carbon-14 sample processing module 310 is connected to the aerosol and iodine treatment module 210, using purified gas filtered by aerosol and iodine as the sample gas. The tritium and carbon-14 sample processing module 310 includes a high-temperature catalytic oxidation furnace, a semiconductor refrigeration condenser, and an alkaline absorption device, used to convert gaseous tritium (HTO vapor) and organic carbon (containing C⁻¹⁴) into water tritide (HTO) and carbon dioxide (¹⁴CO₂), respectively. Subsequently, HTO is condensed into liquid water and collected using a semiconductor refrigeration condenser (-80°C); carbon dioxide is absorbed by sodium hydroxide (NaOH) solution. After the above treatment, gaseous tritium (HTO vapor) and carbon-14 (in...) are... 14The tritium (CO2 form) is converted into a measurable liquid form. The tritium detection module 320 and the carbon-14 detection module 330 are connected to the tritium and carbon-14 sample processing modules 310, respectively. The liquid sample condensed by the semiconductor refrigeration condenser and the liquid sample absorbed by the sodium hydroxide solution are respectively transported to the tritium detection module 320 and the carbon-14 detection module 330 through pipelines. Both the tritium detection module 320 and the carbon-14 detection module 330 are β-array liquid scintillation detectors. The processed liquid sample is injected into the β-array liquid scintillation detector for measurement. The β-array detector uses coincidence counting technology, which can effectively reduce the background.

[0025] An inert gas β monitoring module 400 is located in the third integration area 130. This module is used to separate, enrich, and measure various inert gas nuclides, including radioactive krypton (e.g., Kr-85) and xenon (e.g., Xe-133, Xe-135). The inert gas β monitoring module 400 includes a krypton-xenon processing module 410, a radioactive krypton detection module 420, and a radioactive xenon detection module 430. The krypton-xenon processing module 410 is connected to the aerosol and iodine processing module 210 and is used to separate radioactive krypton and radioactive xenon nuclides. Specifically, the krypton-xenon processing module 410 utilizes a combination of cryogenic adsorption (e.g., using a cold trap at liquid nitrogen temperature with 100-mesh activated carbon particles as the adsorption medium) and gas chromatography to achieve effective Kr / Xe separation. The radioactive krypton detection module 420 and the radioactive xenon detection module 430 are respectively connected to the krypton-xenon processing module 410. The radioactive krypton detection module 420 uses a plastic scintillation fiber (PSF) detector to perform β-count measurements on the separated krypton sample, enabling quantitative analysis of Kr-85 activity concentration. The radioactive xenon detection module 430 integrates a PIPSBox silicon detector and a high-resolution cadmium zinc telluride (CZT) detector. The PIPSBox silicon detector is used for β-count measurements on the separated xenon sample, while the high-resolution CZT detector is used for gamma-ray detection. The two work together to effectively reduce background interference and achieve high-sensitivity identification and measurement of multiple xenon isotopes such as Xe-131m, Xe-133, and Xe-135. The inert gas gamma nuclide monitoring module 500 is located in the second integration area 120. The inert gas gamma nuclide monitoring module 500 is connected to the aerosol and iodine treatment module 210. It is used to perform accurate qualitative and quantitative analysis and measurement of multiple nuclides (such as Cs-137, Co-60, etc.) in the high-resolution gamma spectrum of gas samples, and to provide cross-validation means for the radioactive krypton detection module 420 and the radioactive xenon detection module 430.

[0026] Please see Figure 2 and Figure 5In one embodiment of the present invention, the monitoring device further includes a buffer tank 600. The aerosol and iodine treatment module 210 is connected to the tritium and carbon-14 sample treatment module 310, the krypton-xenon treatment module 410, and the inert gas gamma nuclide monitoring module 500 via the buffer tank 600. Specifically, the buffer tank 600 serves as a gas sample distribution and pressure stabilization hub, used to receive purified gas after aerosol filtration and iodine adsorption, for storing and stabilizing the airflow, ensuring that the airflow pressure and flow rate entering the subsequent monitoring modules remain stable.

[0027] In one embodiment of the present invention, the aerosol detection module 220 preferably employs a zinc-cadmium telluride detector, as it can operate at room temperature without liquid nitrogen cooling, has a compact structure, and is suitable for long-term online monitoring in this integrated system. In scenarios requiring extremely high energy resolution, a high-purity germanium (HPGe) gamma spectrometer can also be used. High-resolution detectors are used for continuous or periodic gamma spectral analysis of radioactive aerosol samples, exhibiting good energy resolution and enabling accurate qualitative and quantitative analysis of multiple radionuclides in aerosols. In another embodiment, the aerosol detection module 220 can also employ a high-purity germanium gamma spectrometer for continuous or periodic gamma spectral analysis of radioactive aerosol samples. In other embodiments, the aerosol detection module 220 can also employ other types of high-resolution energy spectral gamma detectors, but this is not a limitation.

[0028] In one embodiment of the present invention, the inert gas gamma nuclide monitoring module 500 preferably employs a high-purity germanium detector (HPGe detector) because of its excellent energy resolution, enabling precise nuclide identification and quantification of inert gas nuclides with complex energy spectra (such as Ar-41, Xe-131m, Xe-133, Xe-133m, Xe-135, etc.). Simultaneously, the monitoring results of Xe-131m, Xe-133, Xe-133m, Xe-135, etc., can be compared and cross-validated with the results of the radioactive xenon detection module 430. In specific implementations, data from the radioactive xenon detection module 430 is preferably used as the reported data.

[0029] Please see Figure 1 and Figure 5 In one embodiment of the present invention, the monitoring device further includes a cleaning module 700, which is installed in the second integration area 120 and connected to the tritium detection module 320 and the carbon-14 detection module 330. The cleaning module 700 is used to perform a cleaning procedure on the sample flow path and measurement chamber of the tritium detection module 320 and the carbon-14 detection module 330 after each measurement process or when a preset cycle is reached, to prevent cross-contamination and background accumulation caused by sample residues, and to ensure the accuracy of data from long-term continuous monitoring.

[0030] Please see Figure 1In one embodiment of the present invention, the cabinet 100 further includes a high-voltage area 140 and a low-voltage area 150, with a physical distance of not less than 30 cm between the high-voltage area 140 and the low-voltage area 150. Specifically, in this embodiment, the high-voltage area 140 is located above the second integrated area 120, and the low-voltage area 150 is located above the first integrated area 110. By spatially separating the high-voltage lines and maintaining a certain physical distance between them, the electromagnetic coupling effect can be reduced, ensuring the accuracy of data acquisition and the stability of signal processing when the monitoring device performs multi-nucleoside online monitoring of gaseous effluents.

[0031] Please see Figure 1 and Figure 4 In one embodiment of the present invention, the monitoring device further includes an industrial air conditioner 800, which is installed in the third integrated area 130 within the cabinet 100 and connected to the second integrated area 120 and the first integrated area 110. The industrial air conditioner 800 can adjust the internal temperature of the cabinet 100 in real time, ensuring that the high-precision detection instruments inside the cabinet always operate in an optimal temperature environment, effectively preventing energy spectrum drift or measurement errors caused by temperature fluctuations.

[0032] Please see Figure 2 In one embodiment of the present invention, the monitoring device further includes a UPS power supply 900, which is installed in the lower part of the third integrated area 130. The UPS power supply 900 is electrically connected to the aerosol and iodine monitoring module 200, the tritium and carbon-14 monitoring module 300, the inert gas β monitoring module 400, and the inert gas γ nuclide monitoring module 500, respectively. The UPS power supply 900 is an online uninterruptible power supply system, used to provide continuous and stable power protection for each monitoring module when the main power supply is interrupted or abnormal, ensuring continuous system operation and data integrity.

[0033] Please see Figure 1 In one embodiment of the present invention, the cabinet 100 further includes a slide rail 1000. The tritium and carbon-14 sample processing module 310 are slidably connected to the cabinet 100 via the slide rail 1000 and are configured to be at least partially slidable outside the cabinet 100. This allows operators to smoothly pull the module out of the cabinet 100 for operation without disassembling a large number of fixing screws or moving the entire device. This enables routine maintenance, reagent replacement, pipeline cleaning, and troubleshooting to be carried out directly in an open space, significantly reducing the technical threshold and labor intensity of maintenance personnel, and significantly reducing maintenance complexity and downtime.

[0034] Please see Figure 1 and Figure 5In one embodiment of the present invention, the monitoring device further includes a purging module 1100, which is connected to the krypton-xenon processing module 410. The purging module 1100 is used to purge the krypton-xenon processing module 410 and its downstream radioactive krypton detection module 420 and radioactive xenon detection module 430 with high-purity nitrogen after each measurement process or at a preset cycle, to remove residual gases, prevent cross-contamination between different batches of samples, and ensure the accuracy and reliability of long-term monitoring data.

[0035] Further, please refer to Figure 1 In one embodiment of the present invention, lead shielding bodies are respectively provided on the exterior of the tritium detection module 320 and the carbon-14 detection module 330. The independently provided lead shielding bodies effectively isolate the detectors of each detection module in terms of physical space and radiation shielding, ensuring the independence of each measurement channel, eliminating the risk of crosstalk between channels, and making the measurement data of each nuclide more accurate and reliable. At the same time, the lead shielding bodies absorb or attenuate background radiation from the external environment, preventing it from entering the detector interior, thereby effectively reducing the detector's background count and noise level.

[0036] The monitoring device of this invention also includes conventional functional modules and systems such as a reagent module, a measurement and control system, and a flow control system (including a flow pump and a multi-way switching valve). The reagent module is used to store necessary reagent solutions such as alkaline absorption solution, scintillation solution, carrier reagent, and eluent required for multi-nucleoside measurement. The flow control system includes a high-precision syringe pump and a multi-way switching valve, configured to distribute the same sample or different samples to different flow paths. The measurement and control system includes a programmable logic controller (PLC) and an industrial computer. The PLC is configured to execute automated processes, and the industrial computer is configured to perform data interaction. It should be noted that in this embodiment, the reagent module, measurement and control system, and flow control system are all integrated in the integration area within the cabinet 100.

[0037] This invention proposes a modularly integrated online monitoring device for multiple radionuclides in gaseous effluents. The device divides the cabinet into three integration zones, integrating aerosol and iodine monitoring modules, tritium and carbon-14 monitoring modules, and inert gas β and inert gas γ nuclide monitoring modules into their respective zones. This achieves integrated system detection of multiple key radionuclides, including aerosols, iodine, tritium, carbon-14, and radioactive inert gases (such as Kr, Xe, and Ar). The compact layout of this monitoring device enables integrated operation and control, allowing for online monitoring of various radionuclides in gaseous effluents from nuclear power plants and other nuclear facilities, thus improving monitoring efficiency. This addresses the technical problem of the lack of integrated systems for monitoring radionuclides in gaseous effluents at existing nuclear power plants.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
