2-20. EMERGENCY PROCEDURES.
The 300K Water Storage and Distribution System provides sufficient water storage and pumping capacity to allow
isolation and redirection of water flow around failed components without a severe drop in operational capacity.
a. 350 Gpm Pump (P1) Failure. Refer to figure 2-24.
Shut down 350 gpm pump P1 Refer to the applicable TM.
Close gate valves V1 and V2.
If closed, open gate valves V3 and V4.
Start and operate 125 gpm pump P2. Refer to the applicable TM.
Continue to operate water system using 125 gpm pump.
b 125 Gpm Pump (P2) Failure. Refer to figure 2-24.
Shut down 125 gpm pump P2 Refer to the applicable TM.
Close gate valves V3 and V4.
If closed, open gate valves V1 and V2.
Start and operate 350 gpm pump P1 Refer to the applicable TM.
Continue to operate water system using 350 gpm pump.
c. Component Failure. Refer to figure 2-24. In the event of a hose, coupling, tank or valve rupture, the failed
component must be isolated as soon as possible to stop the loss of water.
To prevent injury to personnel, do not attempt to grab whipping hose.
(1) If ruptured hose is whipping, shutdown all water pumps.
To prevent damage to the equipment, water system must be shut down if isolating failed component(s) will
block water flow to or from either 350 gpm pump connection kit
(2) Close nearest upstream and downstream control valves to stop water flow through failed component
(3) If failed component is located in one of the 125 gpm pump connection kits, shutdown the 125 gpm pump
and start the 350 gpm pump. Refer to the applicable TMs.
Continue operation with failed component isolatedfrom system.
