N2 - 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.
