WEAR EVALUATION SUPPORT METHOD, WEAR DEVELOPMENT ESTIMATION SUPPORT METHOD AND INSPECTION SUPPORT METHOD FOR CONTROL ROD CLUSTER GUIDE PIPE, AND PROGRAM AND SYSTEM THERFOR

摘要

PROBLEM TO BE SOLVED: To provide a wear evaluation support method, a wear development estimation support method, and an inspection support method for control rod cluster guide pipe, and program and system therefor, capable of supporting inspection based on technical rationality while ensuring high soundness in the function of a nuclear reactor. SOLUTION: This system 1, to which these methods are applicable, is provided with a calculating means 3 for calculating a wear length based on a picked-up image in which a wear target part of a guide plate 853 for guiding the control rod cluster 72 in the control rod cluster guide pipe 85 is imaged, and a preset means 4 of presetting a control wear length for evaluating a calculated value of the wear length based on a maximum wear length, and is constituted so as to support evaluation or the like of wear condition of the control rod cluster guide pipe.
