Expanding the use of operating experience in fire PRA

Nowlen, Steven P.

Under traditional fire PRA methods, operating experience was used primarily to support statistical analysis of fire frequencies for specific plant locations and/or specific classes of fire ignition sources. While this application of the data continues, recent efforts to improve fire PRA methods, tools, and data are drawing more widely on insights from operating experience. This paper will describe some of the ways in which operating experience is being used to support fire PRA development activities.
