This research is supported by a case study: during an assessment of safety and radiation protec-tion management of nuclear power plant maintenance outages, conducted by IRSN, (a French public institute, i.e. the technical support organization that supports the nuclear safety authority (ASN)), IRSN experts have used the knowledge of accidents to conduct an organizational diagnosis. %G English %L irsn-03573055 %U https://irsn.hal.science/irsn-03573055 %~ SHS %~ IRSN %~ UNIV-NANTES %~ INSTITUT-TELECOM %~ CNRS %~ UNIV-ANGERS %~ UNIV-LEMANS %~ UNIV-UBS %~ EC-NANTES %~ IFREMER %~ LEMNA %~ UNAM %~ IMTA_SSG %~ IMT-ATLANTIQUE %~ INSTITUTS-TELECOM %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022 %~ NU-CENTRALE %~ PSNEXP %~ SHOT
