Nuclear Risk-Based Inspection Methodology for passive components (NURBIM)

Project ID: FIKS-CT-2001-00172
Funded under: FP5-EAECTP C


Inspection and maintenance of nuclear power plants (NPPs) is a prerequisite for safe operation but represents a significant burden for plant operators in Europe. If the European nuclear industry is to remain competitive and maximise its contribution to the reduction of global warming, then more focussed inspection and maintenance schedules are needed that will reduce costs and outage times, while maintaining or increasing plant safety. The conclusions of EURIS were that this could be best achieved through a `Risk Based Management Philosophy¿. The objective of the project NURBIM (Nuclear Risk Based Inspection Methodology) is to further pursue the recommendations of EURIS and subsequent work of ENIQ TG4 in order to develop improved procedures to identify where the highest likelihood of damage/failure is located in plant and, then, to provide quantitative measures of the associated risks. Within this context, risk is defined in terms of a consequence and the probability of incurring those consequences. Such a risk-based approach would, through the focusing of resources, lead to increased safety, reliability and availability of the overall plant. The NURBIM project will focus on the definition of best practice methodologies for performing risk-based analyses and establishing a set of criteria that can help Regulatory bodies in Europe to accept risk-based inspection (RBI) as a valid tool for managing plant safety.
