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 protected with fire barriers and fire protection systems as described in Regulatory Guide 1.189. 8.1.5 Switchgear Rooms Specific fire protection considerations for review of switchgear rooms include: a. Fire separation of switchgear rooms containing equipment important to safety from the remainder of the plant, including redundant switchgear. b. Fire protection systems including detection and suppression should be installed. Automatic fire suppression systems and/or manual suppression capability should be designed with appropriate consideration for the fire and operational hazards present, including consideration of the effects of inadvertent system operation or failure. 8.1.6 Remote Shutdown Areas Areas providing remote shutdown capability should be separated from the control room complex by barriers having a minimum fire rating of 3 hours. Panels providing remote shutdown capability should be electrically isolated from the control room complex so that a fire in either area will not affect shutdown capability from the other area. The general area housing remote panels important to safety should be provided with automatic fire detectors that alarm locally and alarm and annunciate in the control room. Combustible materials should be controlled and limited to those required for operation. Portable extinguishers and manual hose stations should be readily available in the general area. Locations containing remote shutdown panels must be habitable for under fire and post- fire conditions that require their use. Habitability should also be addressed for remote shutdown panels protected by or adjacent to areas with gaseous fire suppression systems. 8.1.7 Station Battery Rooms Battery rooms important to safety should be protected against fires and explosions.
