based on the largest calculated demand, including system demand and hose stream flow. Regulatory Guide 1.189, Position 3.2.1, NFPA 22, "Standard for Water Tanks for Private Fire Protection," and NFPA 24, "Standard for the Installation of Private Fire Service Mains and Their Appurtenances," provide additional guidance for fire protection water supplies. Common water supplies that serve multiple plants or multiple systems including fire, sanitary water, service water, and/or the ultimate heat sink, must be capable of meeting fire demands under all expected conditions without negative impact on safety functions. Revision 4 - October 2003 24 6.2.2 Fire Pumps Fire pumps should have suitable redundancy and capacity (at least two 100% capacity pumps) to meet the fire flow demands calculated for the system. Specific design criteria are provided in Regulatory Guide 1.189, Position 3.2.2. NFPA 20, "Standard for the Installation of Centrifugal Fire Pumps," provides additional guidelines for fire pump installations. 6.2.3 Fire Mains An underground yard fire main loop should be installed to furnish calculated fire water flow demands, including those for manual suppression. Sectionalizing capability and other design considerations should be provided as described in Regulatory Guide 1.189, Position 3.2.3. NFPA 24 provides additional guidance and references other applicable design codes and standards developed by such organizations as the American National Standards Institute (ANSI) and the American Water Works Association (AWWA). 6.3 Automatic Fire suppression Automatic suppression should be installed as determined by the fire hazards analysis and as necessary to protect redundant systems or components necessary for safe shutdown . Automatic fire suppression systems should be selected on the basis of the hazard. Automatic systems should be designed and installed in accordance with appropriate NFPA standards as follows: • Sprinkler systems - NFPA 13 • Water spray systems -
