This invention belongs to the field of nuclear reactor target safety design, specifically relating to a method and system for calculating the internal pressure of a target based on the amount of tellurium compound. The method first determines the required core data; based on the mass and density of the tellurium compound, the effective volume of iodine vapor inside the target is calculated, where the effective volume is the internal volume of the target minus the volume occupied by the tellurium compound; based on the mass of the tellurium compound, the tellurium element mass fraction, and the number of iodine molecules generated per unit mass of tellurium element, the total amount of iodine vapor is calculated; based on the ideal gas law, the internal pressure of the target is calculated using the total amount of vapor, the gas constant, the operating temperature, and the effective volume. This invention establishes a dynamic correlation between the amount of tellurium compound and the effective volume, clarifies the mass conversion relationship between Te and the tellurium compound, and constructs a high-precision I-131 target internal pressure calculation model, possessing significant engineering application value and theoretical innovation significance.

The identification device (2) is provided with a plurality of detection elements (5) (D [1]-D [M]; and M is a natural number of 2 or more), and an identification unit (11). The plurality of detection elements (5) (D [1]-D [M]) react with different types of substances among the plurality of substances released from the generation source (T), and output a detection value of a magnitude corresponding to the amount of the reacted substance. The identification unit (11) refers to information indicating the relationship between the order of the plurality of detection elements (5) sorted according to the magnitude of each detection value when the plurality of detection elements (5) detect a substance released from a generation source (T) of a known type, and the type of the known generation source (T). On the basis of information indicating the order of the plurality of detection elements (5) when the substance is detected by the plurality of detection elements (5), the type of the source (T) of the substance is identified.

The purpose of the present invention is to provide a method for more accurately quantifying a test substance in a measurement system in which the amount of the test substance is increased or decreased in a measurement device when measuring a sample. A quantification method for quantifying a substance to be detected in a sample containing the substance to be detected, the method being characterized by comprising: (1) a step for measuring the same sample a plurality of times using a measurement device to obtain a plurality of quantitative values for the substance to be detected in the sample; and (2) a step for calculating, from the plurality of quantitative values, an increase / decrease amount of the test substance by the measurement device, and correcting at least one of the plurality of quantitative values by means of the increase / decrease amount to obtain a real quantitative value of the test substance.
