がある。Here, absorption analysis is a method in which the target i8 liquid is irradiated with monochromatic light, the amount of light absorbed is determined from the intensity of the transmitted light, and the concentration is thereby measured.As an analytical method, the principle is simple.
It has the advantage of being easy to handle. However, since it accounts for the attenuation due to the absorption of incident light, it is not very suitable for trace measurement, and it has drawbacks such as the inability to measure transmitted light if light is absorbed by substances other than the analyte (solvent and impurities). There is.

感であるという欠点がある。On the other hand, fluorescence analysis is a method in which atoms are excited by excitation light.
This method measures the fluorescence emitted when molecules return to their ground state and determines the concentration of a substance from the intensity of the fluorescence.The analytical sensitivity is generally one to two orders of magnitude better than that of absorption spectroscopy, making it suitable for trace analysis. It is known. However, compared to absorption spectrometry, it is more sensitive to sample conditions, such as energy transfer to the solvent and impurities during the process of generating fluorescence, resulting in non-radiative relaxation, and the degree of relaxation changing depending on the solution temperature. There is a drawback.

光分析法が適切といえる。In general, absorption spectrometry is appropriate when the solution to be analyzed has high transparency and the substance to be analyzed has a high degree of α, while fluorescence analysis is appropriate under other conditions.

数の分析法を簡単に選択できるものでなかった。Fluorescence analysis and absorption analysis are widely used as methods for analyzing the concentration of sensitive substances, but when dealing with samples containing nuclear materials, there is a problem of radiation exposure, and humans must directly handle the samples. In addition, special measures must be taken for processing the sample after analysis. Furthermore,
When analyzing solutions containing F, p, (JF fission products) and cladding, such as reprocessed solutions, it is difficult to uniquely determine the analytical method, and it is difficult to uniquely determine the analytical method, and it is difficult to uniquely determine the analytical method. It is necessary to use different analytical methods, but in the past it was not possible to easily select multiple analytical methods using a single device.

生ずることが予想される。Furthermore, when glass material is used for the thread path that transmits excitation light, fluorescence, and transmitted light, if it is used for a long time in a radiation environment, the glass material deteriorates and its transmittance decreases, causing errors in measured values. It is expected that this will occur.

インライン分析が可能である。Side fluorescence is obtained from the side surface, and transmitted light for absorption analysis is obtained from the surface that has passed through the sample, so that the analysis light can be selected depending on the condition of the sample. The sample cell is installed in the middle of a branch pipe that takes the sample from the pipe through which the sample to be analyzed flows and returns the sample after analysis.
Inline analysis is possible.

排除できる。In the present invention, it is possible to process nuclear materials directly into the sample cell in an in-line manner for analysis, and it is also possible to select the light-based analysis method most suitable for the state of the sample from among surface fluorescence, side fluorescence, and absorption. This also eliminates the influence of reduced transmittance of the optical fiber.

, 212.213 reflection mirror and 221°222.22
The three combinations of condenser lenses are replaced by one condenser mirror 231, 232, and 233, respectively. That is, the surface fluorescence condensing mirror 231 captures and condenses the surface fluorescence from the sample cell 5, changes the optical path, and sends it to the surface fluorescence optical fiber 101. For this reason, the surface fluorescence condensing mirror 23
Reference numeral 1 designates an asymmetric spherical mirror, and a small diameter hole 24 is placed in the center of the mirror on the axis connecting the excitation light reflecting mirror 20 and the sample cell 5 for the passage of excitation light. The side fluorescence condensing mirror 232 and the light absorption condensing mirror 233 are also asymmetric spherical mirrors, but do not have small diameter holes. By using the condensing mirrors 231, 232, and 233, it is possible to reduce the light intensity loss caused by each analytical light passing through the lenses 221°, 222, and 223 in FIG. It is possible to delete certain lenses. Lens materials are generally glass materials and are susceptible to radiation.
Since the surfaces of the condensing mirrors 231, 232, and 233 are made by metal vapor deposition, they are more resistant to radiation than glass.

This is because the temperature of the non-transmissive cell material 27 is measured by the temperature detection unit 28, and the temperature of the solution in the sample cell 5 is detected using the external conduction rate of the non-transmissive cell material 27, since this affects the absorption analysis. . The temperature detection unit 28 is the temperature detection optical fiber 15
It is connected to temperature detector 1G via. In concentration analysis, it is sufficient to create a temperature detection line in advance.
次に第５図を用いて、本濃度分析装置における放射線の

る。First, what must be corrected in concentration analysis is
This is a decrease in the transmittance of the excitation light optical fiber 9, the sample cell 5, and each of the analysis light optical fibers 101, 102, and 103. As for the optical fibers, the optical fiber damage monitoring optical fiber 18 is installed so as to be routed in almost the same way as the excitation light optical fiber and each analysis light optical fiber. By comparing the transmittance of the optical fiber damage monitoring optical fiber 18 in its initial state with no radiation damage and the transmittance after it has been used in a radiation environment, it is possible to measure how much radiation damage has occurred. From this loss A1, a pumping light optical fiber 9. Each analytical light optical fiber 101. io2

Since the damage can be calculated using the optical fiber 18 for monitoring optical fiber damage, the degree of damage to the sample cell 5 can be corrected more accurately using this value.
