Problems solved by technology

[0003] There are hundreds of fuel assembly simulants in the mixing test in the lower chamber. In the past, only one conductance electrode was arranged for each fuel assembly simulant. The damage rate of the conductance electrode in the test was as high as 10%, resulting in bad points in the test. whole

Abstract

The invention discloses a method and system for post-processing the data of a reactor lower chamber mixing test. The invention intends to measure the transient measurement solution of two main and standby conductance electrodes in a plurality of fuel assembly simulation bodies during a reactor lower chamber mixing test After the concentration of the test data is obtained, a complete set of post-processing method for the test data can be established. According to this method, the damaged conductivity electrode can be completely and accurately identified, and it can be judged as a bad point. This method can also accurately calculate the background average concentration of the conductivity electrode. , and in the wave peak stage, the most stable time period can be found for calculating the average concentration of the wave peak, which provides input data for the calculation of the mixing factor in the lower chamber mixing test of the reactor.

Description

technical field [0001] The invention relates to the field of mixing tests in the lower chamber of a reactor, in particular to a method and system for post-processing data of the mixing test in the lower chamber of a reactor. Background technique [0002] The mixing test in the lower chamber of the reactor is a hydraulic test, and the mixing factor in the lower chamber of the reactor is obtained by injecting KCL solution into a certain loop. During the mixing test, it is necessary to measure the KCL solution concentration in the simulated body of the fuel assembly, and the instrument for measuring the concentration once is a conductivity electrode. The lower chamber mixing factor provides data input for reactor thermal-hydraulic and safety analysis. [0003] There are hundreds of fuel assembly simulants in the lower chamber mixing test. In the past, only one conductivity electrode was arranged for each fuel assembly simulant. The damage rate of the conductivity electrode in ...
