Its application in the nuclear industry is closely related to the PRA (Probabilistic Risk Assessment) results of individual power plants. Of special interest is the issue of Regularity Guide 1.178 by NRC in the year of 1997. In that Guide, an individual power plant is allowed to apply to NRC for the relief of the originally required tedious ISI procedure and replace it with an appropriate RI-ISI (Risk-Informed In-Service Inspection) plan. Once approved by NRC after careful review of the RI-ISI plan, the plant owner can perform more cost-efficient in-service inspection while still maintain the required plant safety. In fact, many nuclear power plants in the USA have applied to NRC for approvals of such RI-ISI plans. The purpose of the present study is to collect the RI-ISI knowledge and information from the USA side and introduce some related concepts to the domestic nuclear engineers. An academic research related to the RI-ISI will be carried out as well. In the research, probabilistic fracture analysis will be performed to calculate the (potential) failure probabilities of nuclear components or piping segments. The results will be used in conjunction with an individual power plant’s PRA results to construct a so-called “risk matrix.” Decision can then be made for an appropriate RI-ISI plan for the individual power plant. Experience gained from the above academic analysis will be combined with the knowledge absorbed from the collected foreign literatures. Suggestions will be made for the future employment of RI-ISI once AEC decides to adopt the RI-ISI policy.風險告知決策在役檢測機率風險評估機率失效分析核能管路Risk-Informed Decision MakingRisk-Informed In-Service InspectionProbabilistic Risk AssessmentProbabilistic Fracture AnalysisNuclear Piping
