  1. IDA cognitive model for the analysis of nuclear power plant operator response under accident conditions. Part I : Problem solving and decision making model.

    Article - En anglais

    This paper is the first of a series of papers describing IDA which is a cognitive model for analyzing the behaviour of nuclear power plant operators under accident conditions.

    The domain of applicability of the model is a relatively constrained environment where behaviour is significantly influenced by high levels of training and explicit requirement to follow written procedures.

    IDA consists of a model for individual operator behaviour and a model for control room operating crew expanded from the individual model.

    The model and its derivatives such as an error taxonomy and data collection approach has been designed with ultimate objective of becoming a quantitative method for human reliability analysis (HRA) in probabilistic risk assessment (PRA).

    The present paper gives a description of the main components of IDA such as memory structure, goals, and problem solving and decision making strategies.

    It also identifies factors that are at the origin of transitions between goals or between strategies.

    These factors cover the effects of external conditions and psychological state of the operator.

    The description is generic at first and then made specific to the nuclear power plant environment and more precisely to abnormal conditions.
