The paper presents a method developed for the analysis of the management of NPP fire situations from the point of view of the control room. The way of analysis helps in gaining more understanding of fire situations as a context of operators' judgment and decision-making. The focus of the analysis is on the safety-critical significance of the way of forming an idea of the relevant matters of the situation and of the organizational support to making the assessments. The application of the method to particular fire situations makes it possible to identify the case-specific risk-informed ways of acting. The method offers a framework for the integration of the multidisciplinary expertise related to NPP fire situations. It can be used to support the management of fire situations and to improve the realism of fire risk analyses.
