systems, and components important to safety. Thus, a fire involving one success path of safe shutdown equipment may constitute an exposure fire for the redundant success path located in the same area, and a fire involving combustibles other than either redundant success path may constitute an exposure fire to both redundant trains located in the same area. Fire Area — The portion of a building or plant that is separated from other areas by rated fire barriers adequate for the fire hazard. Fire Barrier — Components of construction (walls, floors, and their supports), including beams, joists, columns, penetration seals or closures, fire doors, and fire dampers that are rated by approving laboratories in hours of resistance to fire, that are used to prevent the spread of fire. Fire Brigade — A team of on-site plant personnel that have been qualified and equipped to perform manual fire suppression activities. Fire Hazard — The existence of conditions that involve the necessary elements to initiate and support combustion, including in situ or transient combustible materials, ignition sources (e.g., heat, sparks, open flames), and an oxygen environment. Fire Hazard Analysis — An analysis used to evaluate the capability of a nuclear power plant to perform safe shutdown functions and minimize radioactive releases to the environment in the event of a fire. The analysis includes the following features:  Identification of fixed and transient fire hazards.  Identification and evaluation of fire prevention and protection measures relative to the identified hazards.  Evaluation of the impact of fire in any plant area on the ability to safely shut down the reactor and maintain shutdown conditions, as well as to minimize and control the release of radioactive material. Fire Protection Feature — Administrative controls, emergency lighting, fire barriers, fire brigade personnel, and other features provided for fire protection purposes.
