Management of operational documentation ASN considers that the operational documentation is still not fully adequate in 2021. This has been a recurring fundamental problem for several years now. In 2021, the inspections again found numerous events for which the root causes included documentary problems. The weak points identified vary in nature (documentation not concise enough, not explicit, incomplete or non-existent) and have consequences for a wide range of activities, including control activities (periodic tests, lock-outs and administrative closures, alignment) and maintenance work (technical inspections, maintenance work on equipment, requalifications, local control actions). These weak points are to a large extent related to organisational malfunctions in the documentation creation and update process and they potentially compromise the documentary support line of defence. The Operating Experience Feedback process All the NPPs have implemented a formal organisation and dedicated tools to oversee and coordinate internal and external Operating Experience Feedback (OEF). The inspections targeted on OEF management underlined the overall engagement by the management of the NPPs on this subject. All those persons encountered, including outside contractors, showed a good level of involvement in the process. Weak points however persist on certain key aspects of this process, such as the incorporation of OEF into the activities preparation phases, or the transmission of difficulties encountered in the field (the quality of the debriefings fluctuates considerably from one discipline to another). ASN also finds that the annual process reviews conducted by the sites are extremely pertinent, with the actors involved well able to identify weaknesses in OEF management.
