d address the following items. 2.1 Fire Hazards The fire hazards should be identified specifically, typically by fire area. The fire hazards for a plant undergoing decommissioning may be significantly different from those for an operating plant, and they may change as decommissioning progresses. The fire hazards analysis should consider the potential for increased combustible loading from sources such as equipment laydown areas, waste accumulation and storage areas, and materials necessary to support decontamination and dismantlement activities. Hot work involving open flames or sparks is also likely to increase during decommissioning. Other fire hazards may include temporary structures and support systems (e.g., electrical, heating, and ventilation) that may affect the fire hazards in the plant. 2.2 Physical Plant Configuration and Condition The fire hazards analysis should describe the layout, configuration, and condition of the plant fire areas and should be updated to reflect any significant changes that occur through the various decommissioning phases. Dismantlement of or modifications to facility structures and the deactivation, modification, or removal of plant systems may affect fire protection program elements. 2.3 Fire Protection Program Elements The fire hazards analysis should describe the administrative controls, physical protection features (fire detection, suppression systems, and fire barriers), smoke exhaust systems, emergency response capabilities, and any other pertinent elements of the administrative and physical fire protection program that protect against the identified fire hazards. 2.4 Radiological Hazards and Systems Important to Safety The fire hazards analysis should identify the radiological hazards by fire area and, as appropriate, identify the SSCs, such as the plant ventilation systems, necessary to prevent or mitigate the release of radioactive materials in a fire. Consideration should be given to the control of runoff from fire
