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 mixing test data of a lower chamber of a reactor. In a reactor lower chamber mixing test, after instantaneously measuring the solution concentration by using a main conductive electrode and a standby conductive electrode in a plurality of fuel assembly simulators to obtain test data, a set of complete test data post-processing methodis established; according to the method, the damaged conductive electrode can be completely and accurately identified and judged as a defective point, the background average concentration of the conductive electrode can be accurately calculated, the most stable time period can be found in the wave crest stage to be used for calculating the wave crest average concentration, and input data are provided for calculating the cross-mixing factor for the cross-mixing test of the lower chamber 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 circuit. 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 ...
