n devices. b. Inspection, testing and maintenance of installed fire protection systems. Fire protection systems include passive fire protection systems such as fire barrier components and fire barrier seals; and active fire protection systems such as fire alarm systems, fire suppression systems, and fire water supply systems. c. Controls for identification, prioritization and timely correction of fire protection impairments, informing fire protection staff of the impairment, and establishing compensatory measures for the duration of the impairment, including control of hazardous work activities (e.g., hot work) during system impairments. d. Control of fire area boundaries/barriers, including the maintenance of these structures as the facility is modified or dismantled during decommissioning. 3.7 Control of Structures, Enclosures, and External Areas The fire protection program should address fire hazards created by the construction and location of temporary enclosures and structures. Temporary structures should not present a fire exposure hazard to plant structures containing radioactive materials, radioactive contamination, or contaminated waste material accumulation or storage areas. The fire protection program should identify controls to protect structures containing radioactive materials from an exposure fire. The fire hazard presented by transient combustibles, including stored materials, debris, vegetation, and near-by or co-located structures, should be considered. 4. Physical Fire Protection Features Physical fire protection features (e.g., barriers, detection, and suppression) will change with changing hazards as a plant is permanently shut down and decommissioned. The fire hazards analysis should specify the physical fire protection features necessary to minimize the potential for a fire to result in the release or spread of radioactive materials. 4.1 Fire Detection and Alarms Systems Revision 4 - October 2003 48 Detection systems in operating reactor
