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.
