A method for constructing and controlling a turbulence form of a fluid inside a reactor pressure vessel. The method comprises: step S1, obtaining related data of vortexes, a temporal distribution characteristic, a spatial distribution characteristic and a power spectral density of turbulence in an inlet area of each fuel assembly, and a turbulence energy spectrum; step S2, obtaining a water gap change situation of each fuel assembly, and on the basis of the water gap change situation of each fuel assembly, determining whether a three-dimensional flow field model of each fuel assembly needs to be corrected, until a water gap of each fuel assembly does not change; step S3, obtaining a reactor core nuclear power fluctuation amplitude value between fuel assemblies; and step S4, determining whether the reactor core nuclear power fluctuation amplitude value falls within a target range, and if the reactor core nuclear power fluctuation amplitude value does not fall within the target range, changing a three-dimensional structure inside a reactor pressure vessel until the reactor core nuclear power fluctuation amplitude value falls within the target range. The method for constructing and controlling a turbulence form of a fluid inside a reactor pressure vessel can eliminate or ameliorate the nuclear power fluctuation of a reactor core, reduce the wear of grids of the reactor core, and ensure the safety of reactor operation.

The value-taking analysis method comprises: acquiring at least one preset default value of a target signal, and failure association data capable of representing actions correspondingly executed by a control system after the target signal fails (S10); on the basis of the failure association data, performing influence degree analysis processing on each preset default value, so as to obtain a discovery difficulty score, an influence degree score and a redundancy degree score (S20); and on the basis of the discovery difficulty score, the influence degree score and the redundancy degree score which correspond to each preset default value, determining a total score corresponding to each preset default value, and determining a settable default value of the target signal on the basis of all total scores (S30). The value-taking analysis method and the terminal device can help a worker to rationally evaluate the rationality of each preset default value of a control signal, and recommend the most rational default preset value to the worker as a recommended value of a default value.
