f contaminated liquid and gaseous release d. Due to potential limits on containment accessibility during and post-fire, the fire hazards analysis should evaluate the effects of postulated fires on the integrity of containment, the primary coolant system, and safe shutdown systems assuming no action is taken to suppress the fire. 8.1.2 Control Room Complex Revision 4 - October 2003 32 Redundant systems important to safety are in close proximity in the control room areas and there is a significant hazard present from cables and other electrical equipment in the area. Therefore, fire protection in the control room is extremely important to the protection of these systems. Specific consideration in reviewing control room fire protection include: a. Separation by fire barriers from the effects of fires in adjacent areas. b. Interior finishes (e.g., carpeting) should be non-combustible or of limited combustibility as established by testing (see Section C.7.1.3). c. Fire detection as well as manual and automatic suppression capability should be provided as described in Regulatory Guide 1.189, including protection of equipment important to safety from inadvertent operation or failure of the suppression systems. Cable raceways under raised floors should be reviewed to determine if adequate fire detection and suppression are provided for potential fires in these areas. d. Ventilation systems should provide for smoke control and removal and habitability of the control room under fire and post-fire conditions should be addressed in the fire protection. Revision 4 - October 2003 33 8.1.3 Cable Spreading Room Cable spreading rooms should provide for adequate separation of redundant systems. If adequate separation is not possible, an alternative, dedicated, or backup shutdown capability should be provided. The layout and protection of cable spreading rooms should, at a minimum, meet the criteria in Regulatory Guide 1.189. 8.1.4 Plant Computer Rooms Computer rooms should be
