On this page: Publication Information AbstractDownload complete document NUREG/CR-7197, Final Report (PDF – 16.44 MB)Publication Information **Manuscript Completed:** February 2015**Date Published:** April 2016 **Prepared by:** Kevin McGrattan Scott Bareham National Institute of Standards and Technology Engineering Laboratory; Fire Research Division Gaithersburg, MD 20899 David Stroup, NRC Project Manager **Prepared for**: Division of Risk Analysis Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Availability Notice Abstract This report documents an experimental program to explore the heat release rate and burning behavior of electrical enclosures commonly found in nuclear power plants. Electrical enclosures are a potential source of fire in nuclear power plants because they contain both combustible materials and live electrical circuits. These fires have the potential to disrupt power, instrumentation, and control in the plant. Key parameters affecting fire in an enclosure include its size, openings, electrical voltage, and combustible load.
