uel Areas Portable hand fire extinguishers should be located near this area. Also, hose stations should be located outside but within hose reach of this area. Automatic fire detection should alarm and annunciate in the control room and alarm locally. Combustibles should be kept to a minimum in the new fuel area. The storage area should be provided with a drainage system to prevent accumulation of water. The storage configuration of new fuel should always be maintained to preclude criticality for any water density that might occur during fire-water application. 6.2.2 Spent Fuel Areas Local hose stations and portable fire extinguishers should provide protection for the spent fuel pool. Automatic fire detection should alarm and annunciate in the control room and alarm locally. RG 1.191 provides additional guidelines for fire protection of spent fuel areas for permanently shutdown reactors where removal of the spent fuel to an independently licensed storage facility is incomplete. 6.2.3 Radwaste Building, Radwaste Storage Areas, and Decontamination Areas Radioactive waste buildings, storage areas, and decontamination areas should be separated from other areas of the plant by fire barriers having at least 3-hour ratings. Automatic sprinklers should be used in all areas where combustible materials are located. Alternatively, manual hose stations and portable extinguishers (handheld and large-wheeled units sized according to the hazards) are acceptable. Automatic fire detection should annunciate and alarm in the control room and alarm locally. Ventilation systems in these areas should be capable of being isolated to prevent the release of radioactive materials DG-1359, Page 98 to other areas or the environment. Water from firefighting activities should drain to liquid radwaste collection systems. Materials that collect and contain radioactivity, such as spent ion exchange resins, charcoal filters, and HEPA filters, should be stored in closed metal tanks or containers that
