Embodiment 1

[0058] Such as figure 1 As shown, this embodiment discloses a sample analysis method of a spent fuel reprocessing plant, which includes:

[0059] Establish sample analysis tasks for samples according to sample analysis requirements. Sample analysis tasks include automatic analysis tasks and non-automatic analysis tasks;

[0060] Complete the automatic analysis task of the sample first, and then complete the non-automatic analysis task of the sample.

[0061] In some embodiments, before the sample analysis task is established for the sample, the method of this embodiment further includes: classifying the sample type according to the radioactive level of the sample, and the sample type includes a high-radioactive sample 10, a medium-radioactive sample 20, and a low-radioactive sample 30 (including very low level samples).

[0062] In this example, the radioactive level of the high-level sample is greater than or equal to n×10 9 Bq / L(n6 Bq / L(n9 Bq / L(n6 Bq / L (n<10).

Abstract

The invention discloses a spent fuel post-treatment plant sample analysis method. The method comprises the following steps: establishing sample analysis tasks for a sample according to sample analysis requirements, wherein the sample analysis tasks comprise an automatic analysis task and a non-automatic analysis task; and firstly completing the automatic analysis task of a sample, and then completing the non-automatic analysis task of the sample. The invention also discloses a spent fuel post-treatment plant sample analysis system. The system comprises a transceiving unit, automatic analysis equipment and a non-automatic analysis unit; the transceiving unit is used for receiving the sample and distributing the sample according to a sample analysis task; the automatic analysis equipment is used for receiving the samples distributed by the transceiving unit and automatically analyzing the samples so as to complete an automatic analysis task of the samples; and the non-automatic analysis unit is used for receiving the sample distributed by the transceiving unit and carrying out non-automatic analysis on the sample so as to complete a non-automatic analysis task of the sample. The method and the system solve the problems of low analysis efficiency, low sample utilization rate, poor safety and the like.

Description

technical field [0001] The invention belongs to the field of nuclear technology, and in particular relates to a sample analysis method and system of a spent fuel reprocessing plant. Background technique [0002] The nuclear fuel reprocessing plant mainly stores, shears, dissolves and chemically separates spent fuel discharged from nuclear power plants, extracts and recovers useful products, and properly handles and safely disposes of radioactive waste generated during the process. The analysis laboratory of the post-processing plant is mainly responsible for the analysis of the chemical composition, activity concentration, element composition and content, isotope and physical properties of various material samples in the post-processing process, providing timely and reliable analysis for the operation of the post-processing process As a result, the process is ensured to operate safely, stably, and efficiently, and qualified products are obtained. Since the samples of the po...
