otal containment requirements such as ventilation and control of contaminated liquid and gaseous release. (b) Inside noninerted containment one of the fire protection means stated in Positions C.5.b.1 and C.5.b.2 or the following fire protection means should be provided: separation of cables and equipment and associated nonsafety circuits of redundant trains by a noncombustible radiant energy shield having a minimum fire rating of one-half hour. For new applications, fire protection must be provided for redundant shutdown systems in containment that will ensure, to the extent practicable, that one shutdown division will be free of fire damage.238 (c) In primary containment, fire detection systems should be provided for each fire hazard. The type of detection used and the location of the detectors should be the most suitable for the particular type of fire hazard identified by the fire hazard analysis. A general area fire detection capability should be provided in the primary containment as backup for the above described hazard detection. To accomplish this, suitable smoke or heat detectors compatible with the radiation environment should be installed. (d) Standpipe and hose stations should be inside PWR containments and BWR containments that are not inerted. Standpipe and hose stations inside containment may be connected to a high quality water supply of sufficient quantity and pressure other than the fire main loop if plant-specific features prevent extending the fire main supply inside containment. For BWR drywells, standpipe and hose stations should be placed outside the drywell with adequate lengths of hose, no DRAFT Rev. 4 - April 1996 9.5.1-54 longer than 30 m (100 ft) , to reach any location inside the drywell with an 239 effective hose stream. The containment penetration of the standpipe system should meet the isolation requirements of General Design Criterion 56 and should be seismic Category and Quality Group B. (e) The reactor coolant pumps should be
