METHOD FOR DESIGNING WIRE-SPACER IN FUEL ASSEMBLY OF LIQUID METAL REACTOR AND WIRE-SPACER PRODUCED THEREBY

摘要

A method for designing a wire-spacer in a fuel assembly of a liquid metal reactor and a wire-spacer manufactured by the same are provided to accurately predict a practical thermo hydraulic behavior. A method for designing a wire-spacer in a fuel assembly of a liquid metal reactor includes the steps of: selecting a target function and a design parameter(S10); determining a design range(S20); setting a design point by a DOE(Design Of Experience)(S30); calculating the target function value of the step(S10) for the design point set at the step(S30)(S40); configuring a surrogate model(S50); searching an optimum point on the surrogate model(S60); and outputting the optimum searching result when the optimum point searched at the step(S60) exists at the design region of the step(S20)(S80).
