ram requirements, including consideration of potential hazards associated with postulated fires, with building layout and systems design. (2) Design and maintenance of fire detection, suppression, and extinguishing systems. (3) Fire prevention activities. (4) Training and manual firefighting activities of plant personnel and the fire brigade. (5) Pre-fire planning. On sites where there is an operating reactor and construction or modification pf other units is underway, the superintendent of the operating plant should have the lead responsibility for site fire protection. (NOTE: NFPA 6, "Recommendations for Organization of Industrial Fire Loss Prevention," contains useful guidance for the organization and operation of the entire fire loss prevention program.) b. Fire Hazard Analysis The overall fire protection program should allow the plant to maintain the ability to perform safe shutdown functions and minimize radioactive releases to the environment in the event of a fire. A major element of this program should be the evaluation of potential fire hazards throughout the plant and the effect of postulated fires on safety-related plant areas. Fire initiation should be postulated at the location that will produce the most severe fire, assuming an ignition source is present at that point. Fire development should consider the potential for involvement of other combustibles, both fixed and transient, in..the fire area. Where automatic suppression systems are installed, the effects of the postulated fire sho~ld be evaluated with and without actuation of the automatic suppression system. (1) A detailed fire hazard analysis should be made during initial plant design to reflect the proposed construction arrangement, materials, and facilities. This analysis should be revised periodically as design and construction progress and before and during major plant modifications. (2) The fire hazard analysis should be a systematic study of (a) all elements of the fire protection program
