Fire detection should alarm and annunciate in the control room and alarm locally. Hose stations and portable extinguishers should be readily accessible. Floor drains should be provided to prevent water accumulation from damaging safety- related equipment (see Regulatory Position C.4.a.(9)). Provisions should be made for manual control of the ventilation system to facilitate smoke removal if required for manual firefighting operation (see Regulatory Position C.4.d). 1. New Fuel Area Hand portable extinguishers should be located within 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 limited to a minimum in the new fuel area. The storage area should be provided with a drainage system to preclude accumulation of water. The storage configuration of new fuel should always.be so maintained as to preclude criticality for any water density that might occur during fire water application. m. Spent Fuel Pool Area Protection for the spent fuel pool area should be provided by local hose stations and portable extinguishers. Automatic fire detection should be provided to alarm and annunciate in the control room and to alarm locally. n. Radwaste and Decontamination Areas Fire barriers, automatic fire suppression and detection, and ventilation controls should be provided unless the fire hazard analysis can demonstrate that such protection is not necessary. 0.
