ustibles expected to be used in normal operations such as refueling, maintenance, and modifications; (2) Continuity of combustible contents, furnishings, building materials, or combinations thereof in configurations conducive to fire spread; (3) Exposure fire, heat, smoke, or water exposure, including those that may necessitate evacuation from areas that are required to be attended for safe shutdown; (4) Fire in control rooms or other locations having critical safety-related functions; (5) Lack of adequate access or smoke removal facilities that impede fire extinguishment in safety-related areas; (6) Lack of explosion-prevention measures; (7) Loss of electric power or control circuits; (8) Inadvertent operation of fire suppression systems. The fire hazards analysis should verify that the NRC fire protection program guidelines have been met. The analysis should list applicable elements of the program, with explanatory statements as needed to identify location, type of system, and design criteria. The analysis should identify and justify any deviations from the regulatory guidelines. Justification for deviations from the regulatory guidelines should show that an equivalent level of protection will be achieved. Deletion of a protective feature without compensating alternative protection measures will not be acceptable, unless it is clearly demonstrated that the protective measure is not needed because of the design and arrangement of the particular plant. c. Fire Suppression System Design Basis (1) Total reliance should not be placed on a single fire suppression system. Appropriate backup fire suppression capability should be provided. (2) A single active failure or a crack in a moderate-energy line (pipe) in the fire suppression system should not impair both the primary and backup fire suppression capability. For example, neither the failure of a fire pump, its power supply or controls, nor a crack in a moderate-energy line in the fire suppression system, should
