[0002] During the nuclear fuel cycle, the measurement of nuclear materials runs through the entire nuclear fuel cycle. The total amount of each key measurement material must be accurately measured to ensure the absolute safety of nuclear materials and prevent illegal transfer of nuclear materials. The calorimetric method is used to determine the total amount of nuclear materials in radioactive materials with higher accuracy and precision than other non-destructive analysis techniques. Calorimetry usually uses a highly sensitive and highly automated calorimeter. When nuclear materials undergo radioactive decay, they emit rays of various energies.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the nuclear fuel cycle, the measurement of nuclear materials runs through the entire nuclear fuel cycle. The total amount of each key measurement material must be accurately measured to ensure the absolute safety of nuclear materials and prevent illegal transfer of nuclear materials. The calorimetric method is used to determine the total amount of nuclear materials in radioactive materials. The accuracy and precision are higher than other non-destructive analysis techniques. For some non-uniformly distributed materials, calorimetry is the only effective measurement method. In recent years, due to the rapid development of modern science and technology, especially the rapid development of materials science and electronic technology, extremely accurate measurement and control devices, excellent constant temperature systems and highly sensitive temperature measurement tools have been provided. Therefore, highly sensitive and highly automated calorimeters continue to emerge, making calorimetry and thermodynamics flourish. In the nuclear fuel cycle, the mass or activity of radioactive materials can be determined by measuring the thermal effect of nuclear materials (mainly materials of α and β nuclides).

[0036] When nuclear materials undergo radioactive decay, they emit rays of various energies. These rays are absorbed by the measuring cup of the calorimeter and converted into heat energy. The change in the temperature of the measuring cup is reflected by the thermopile signal of the detection device, so that the thermal power can be obtained. If the unknown source contains only one radioactive nuclide, the power generated can be given by the following formula:

[0037] W u =mP

[0038] Where:

[0039] W u is the power (W) emitted by the unknown heat source;

[0040] m is the mass of the radionuclide (g);

[0041] P is the specific power of the radionuclide (W / g).

[0042] From the above formula, it can be seen that the total mass of radioactive material can be calculated based on the thermal power of the sample, the abundance of radionuclides and the specific power.

[0043] In the actual calorimetry process, in order to accurately measure the radioactive source, choosing high-accuracy and high-precision measuring instruments and methods is the fundamental way to reduce errors. Therefore, accurate calibration and calibration of the calorimeter and other measuring instruments used can improve the accuracy of the measurement results and the reliability of the formulated treatment measures. The calibration of the instrument generally uses an isotope standard heat source, especially an isotope standard heat source, which has the characteristics of high thermal power stability due to the isotope decay not being disturbed by the external environment, making it an excellent measuring tool for calibration. However, during calibration, the thermal power of the isotope standard heat source must be determined first. Related technology In the process of determining the thermal power of the isotope heat source, the process technology is complex and the process cost is high.

[0044] In view of the shortcomings of the above-mentioned related technologies, an embodiment of the present invention provides a calorimeter calibration method, which can improve the reliability of the calorimeter calibration of the radiation source. In order to illustrate the technical solution of the present invention, a specific embodiment is used for description below.

[0045] Figure 1 The embodiment of the present invention provides a schematic diagram of the implementation process of a calorimeter calibration method.

[0047] Here, the embodiment of the present application uses an electric heating simulation device to simulate a standard sample of a radiation source, sets the thermal power of the electric heating simulation device by electric heating, thereby simulating the thermal power of different radiation sources, and uses a calorimeter to calibrate the thermal power of the simulated radiation source.

[0048] The electric heating simulation device can be a heating wire wound around a heating rod, well insulated, connected to a voltage-regulated adjustable DC power supply, and the thermal power of the radiation source can be adjusted by adjusting the voltage and current of the voltage-regulated adjustable DC power supply. The electric heating simulation device can be packaged in a sealed shell, such as a stainless steel shell, to increase durability.

[0049] In one embodiment, the thermal power of the electric heating simulation device can be changed between 0.1W and 1W, and a thermal power can be set at intervals of 0.1W.

[0050] The embodiment of the present application simulates the thermal effect of a radiation source through the electric heating thermal effect of an electric heating simulation device. The material is simple, there is no radioactive hazard, and the safety of calibration workers is guaranteed.

[0053] The potential difference measured by the calorimeter was determined at various heat powers of the electric heating simulation device.

[0054] S103, calibrating the calorimeter based on a plurality of correspondences between thermal powers and potential differences.

[0055] According to the corresponding relationship between multiple thermal powers and potential differences, the radiation sources with different powers can be simulated and calibrated to improve the reliability of the calibration of the radiation source by the calorimeter.

[0056] After the calibration is completed, when the radioactive source sample is measured using the calorimeter, the thermal power of the radioactive source sample can be determined based on the calibration result and the measured potential difference.

[0057] The embodiment of the present application sets multiple thermal powers of an electric heating simulation device, and the electric heating simulation device is placed in the calorimetric container of the calorimeter.

Based on the correspondence between the multiple thermal powers and the potential difference, the calorimeter is calibrated. The present application simulates the thermal effect of the radiation source through the electric heating thermal effect of the electric heating simulation device, without radioactive hazards, to ensure the safety of the calibration staff. In addition, by setting multiple thermal powers of the electric heating simulation device, radiation sources of different powers can be simulated and calibrated, thereby improving the credibility of the calibration of the radiation source by the calorimeter.

[0061] Here, the calorimeter calibration curve can be drawn based on the potential difference corresponding to multiple thermal powers, such as Figure 2 As shown, Figure 2 It is the calorimetric calibration curve of the electric heating simulation device with different thermal powers. Figure 2 The curve shown can be used to calibrate the calorimeter. After calibration, when using the calorimeter to measure the radioactive source sample, Figure 2 The curve shown in Figure 1 determines the thermal power corresponding to the potential difference measured by the calorimeter, which is the thermal power of the radioactive source sample being measured.

After a certain period of time, the temperature of the absorber does not change, and the calorimeter reaches thermal equilibrium. At this time, the potential difference measured by the calorimeter is obtained, and the measured value is accurate, which can improve the accuracy of calibration.

[0069] According to the calorimeter circuit diagram, the electric heating simulation device is connected to the calorimetric circuit.

The electric power curve is drawn to fit the one-to-one correspondence between the power and the potential difference of the thermoelectric element.
