Risk Informed In-Service-Inspection Activities within the European Network for Inspection and Qualification

The European Network for Inspection Qualification (ENIQ) was established in 1992 in response to increasing recognition of the importance of qualification of non-destructive inspection systems used in in-service inspection programs for nuclear power plants. ENIQ has established a Task Group on Risk (TGR) to work towards developing best practice for risk-informed in-service inspection methodologies, with the objective of increasing the safety of European nuclear power plants. In March 2005 TGR published a European framework document for risk-informed in-service inspection. More recently, TGR has been working at producing more detailed recommended practices and discussion documents on several RI-ISI related issues. TGR has published reports on following topics: The role of ISI within the philosophy of defense-in-depth; The verification and validation of structural reliability models to be used in RI-ISI programs; The use of expert panels in RI-ISI; The applicability of RI-ISI to the reactor pressure vessel; and RI-ISI updating. Work is ongoing to develop documents on other RI-ISI related issues. In addition, TGR has been active in initiating international projects, such as the JRC-OECD/NEA coordinated RI-ISI benchmark exercise (RISMET), and a project on the relationship between inspection qualification and RI-ISI. This paper describes the activities and publications of TGR to date.
