<P>PROBLEM TO BE SOLVED: To provide a reactor in-core structure diagnosis system which can promptly and easily conduct and evaluate irradiation induced intergranular segregation for evaluating the irradiation-assisted stress corrosion cracking (IASCC) sensitivity of a reactor in-core structures that are irradiated with neutrons. Ž<P>SOLUTION: The system for in-reactor diagnosis equipment includes: an input unit 1 as a chemical component input means, into which chemical components contained in a material to be diagnosed in a region to be evaluated that is associated with the equipment in the reactor irradiated with neutrons are input; a neutron irradiation condition input means into which doses, speeds and temperatures of neutron irradiation applied to the material to be diagnosed are input and a material physical property data input means into which material physical property data on the material to be diagnosed are input; an arithmetic unit 2 as an analysis means for analyzing the irradiation-induced intergranular segregation of the material to be diagnosed for the equipment in the reactor, on the basis of the data from the input unit 1 as the chemical component input means, the neutron irradiation condition input means and the material physical property data input means; a display 3 as an analysis result displaying means for displaying the analysis results of the irradiation-induced intergranular segregation; and a recorder 5 as an analysis result storing means for storing the analysis results of the irradiation-induced intergranular segregation.
