Heat Release Rates of Electrical Enclosure Fires (HELEN-FIRE)

This report documents an experimental program to quantify 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.
