the effects of fire should request an exemption or deviation as appropriate. 8. Fire Protection of Areas Important to Safety Several areas within a nuclear power plant present unique hazards or design issues relative to fire protection and safe shutdown. This section provides guidelines for the review of fire protection in these areas. More detailed guidelines are provided in Regulatory Guide 1.189. 8.1 Areas Related to Power Operation 8.1.1 Containment Regulatory Guide 1.189 provides specific guidelines on the protection of fire hazards and equipment important to safety in containment. Specific considerations include: a. Separation and other fire protection features of redundant systems in close proximity (e.g., electrical penetration areas and reactor coolant system instrumentation locations). b. Fire protection of containment hazards including lube oils, hydraulic oils, cables, electrical cabinets, and combustible filter media. Refueling and maintenance activities introduce additional transient hazards (e.g., contamination control materials, chemicals, hot work, and scaffolds) that should be evaluated and protected. c. Automatic fire detection and suppression capability inside containment should be described and evaluated in the fire hazard analysis. Manual suppression capability (e.g., standpipes and hose stations) should also be provided and designed to appropriate standards. The design should allow fire suppression attack internal to containment while maintaining containment integrity. Operation of the fire protection systems should not compromise the integrity of the containment or other systems important to safety. Fire protection actions in containment area should function in conjunction with total containment requirements such as ventilation and control of contaminated liquid and gaseous release d. Due to potential limits on containment accessibility during and post-fire, the fire hazards analysis should evaluate the effects of postulated fires on the
