Application of CFAST software to simulate the location of fire sprinklers in nuclear power plant and specification discussion

CFAST software is one of the most mature regional model software which can be applied to simulate the detailed situation in the room of nuclear power plant when fire is occurred, so as to obtain the parameter changes of concerns in the fire room. This paper is to explore the rationality and conservation of the current specification to draw a corresponding conclusion in accordance with the extents of influences on the fire sprayer glass bulb burst time from the different heights, via setting four groups of fire sprayers positions by regarding nuclear power plant motor-driven pump room as the simulation area, and using CFAST software simulation fire sprayer height, according to the corresponding provisions required by the Design Specification of Automatic Spraying Fire-extinguishing System on the distances between the fire sprayer and roof.
