ABSTRACT
An international empirical HRA (human reliability analysis) study has been launched in 2007, with the Halden Research Institute and several HRA experts participating and debating [1]. The method designed and used for Human Reliability Analysis in EDF’s PSA (probability and safety assessment) is MERMOS (in French: ‘‘méthode d’évaluation de la réalisation des missions opérateurs pour la sûreté’’); it is a second generation HRA method [2] [3]. A team from EDF has participated to this international study with the
MERMOS method: indeed it was an opportunity for EDF to make MERMOS more widely understood and to compare different HRA methods through the implementation of common examples. Some first insights have been presented in a paper for PSAM 9: how to describe potential failure and its influencing factors in a given situation [4].
