Abstract
The U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Reactor Regulation (NRR), Division of Systems Safety and Analysis (DSSA), Plant Systems Branch (SPLB), Fire Protection Engineering and Special Projects Section, has developed quantitative methods, known as “Fire Dynamics Tools” (FDT s ), to assist regional fire protection inspectors in performing fire hazard analysis (FHA). These methods have been implemented in spreadsheets and taught at the NRC’s quarterly regional inspector workshops. FDT were developed using state-of-the-art fire dynamics equations and correlations that were preprogrammed and locked into Microsoft Excel ® spreadsheets. These FDT s will enable the inspector to perform quick, easy, first-order calculations for the potential fire scenarios using today’s state-of-the-art principles of fire dynamics. Each FDT s spreadsheet also contains a list of the physical and thermal properties of the materials commonly encountered in nuclear power plants. This NUREG-series report addresses the technical bases for FDT s , which were derived from the principles developed primarily in the Society of Fire Protection Engineers (SFPE) Handbook of Fire Protection Engineering, National Fire Protection Association (NFPA) Fire Protection Handbook, and other fire science literature. The subject matter of this report covers many aspects of fire dynamics and contains descriptions of the most important fire processes. A significant number of examples, reference tables, illustrations, and conceptual drawings are presented in this report to expand the inspector’s appreciation in visualizing and retaining the material and understanding calculation methods.Page Last Reviewed/Updated Thursday, March 29, 2012
