Abstract

Nuclear power plants create a demanding environment for fire fighting and simultaneous process control. The special features of fire situations complicate on-line decision making. They are also problematic from the viewpoint of probabilistic fire analysis. The paper introduces a study, the general goal of which, on one hand, is to enhance knowledge concerning the demands of the control of fire situations and, on the other, to support the human reliability analysis (HRA) relating to NPP fires. The aim of the current phase of the study, described in the paper, has been to gain, with the help of expert interviews, more understanding of the nature and problems of NPP fire situations and of the organizational support of the control of fire situations. In addition, characteristic problems and the way of taking account of human aspects in carrying out the probabilistic safety assessment (PSA) related to fire have been discussed with the interviewees. The experts, 15 persons who represented Loviisa and Olkiluoto nuclear power plants, Radiation Protection Centre (STUK) and Technical Research Centre of Finland (VTT), had different perspectives on fire situations and probabilistic fire analysis. They were representatives of control room shift supervisors, simulator instructors, plant and communal fire brigades, plant fire experts and experts of deterministic fire analysis and probabilistic fire safety assessment. The interviews were designed and carried out on the basis of the integration of psychology and reliability analysis. The paper introduces a summary of the preliminary results of the interviews by presenting the experts' points of view on a general level.
