f drills, and level of offsite fire department support should continue commensurate with the hazards during the decommissioning activities. When the nuclear safety and the radioactive release criteria of Chapter 1 of NFPA 805 no longer apply to the power block, a plant industrial fire brigade and the provisions of Sections 5.3.5.2, 5.3.5.3, and 5.3.5.4 of NFPA 805 will no longer be needed. 6.8 Fire Detection and Alarms The licensee should maintain the fire detection and alarm systems described in the approved NFPA 805 licensing basis to provide a reliable means of detecting a fire, providing notification to a constantly attended location, and alerting the industrial fire brigade and plant personnel of the pending condition. During decommissioning activities, the licensee should determine whether fire detection or alarm systems should be installed or removed as required to protect SSCs to meet the nuclear safety performance criteria described in Regulatory Position C.6.1 of this guide or commensurate with the changes in fire hazards and the potential release of hazardous and radiological materials to the environment. The design of fire detection and alarm systems should meet Section 3.8 of NFPA 805. 6.9 Fire Confinement and Fire Barriers Because of plant changes during decommissioning conditions and activities, the licensee should evaluate the need for fire barriers and fire area boundaries to isolate fire hazards; aid in the ability to DG-1370, Page 24 effectively contain, fight, and control a fire; protect plant personnel evacuation routes; and minimize the spread of radioactive contamination. Fire barriers identified to be maintained should meet Section 3.11 of NFPA 805 for the design of passive fire protection features. 6.10 Life Safety Egress and evacuation routes should be established and maintained. The changing plant configurations during decommissioning activities should be considered when determining the adequacy of egress routes and emergency lighting
