The Fuel Incident Notification and Analysis System (FINAS) is jointly operated by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organization for Economic Co-operation and Development (OECD/NEA). The system is an important tool for international exchange of operating experience from nuclear fuel cycle facilities. FINAS reports contain information about events of safety significance that have occurred at nuclear fuel cycle facilities and describe the root causes and lessons learned from the events. This publication provides a summary of the operating experience feedback from the events reported to FINAS since it was launched in 1992. The publication has a focus on the root causes, lessons identified, and corrective actions taken to prevent the occurrence of similar events. Reference to other publications that cover nuclear fuel cycle facilities' events as well as a description of the operating experience programmes of these facilities is included. The publication is intended to be used by nuclear fuel cycle facilities' operators, regulators, and designers.
