ALTERNATE SHUTDOWN 6oO PURPOSE AND DISCUSSION:
This procedure provides instructions for placing the plant in a safe condition when operations cannot safely be conducted from the Control Room due to a fire in the Control Room and/or Cable Spreading Room The Reactor, Turbine, and Reactor Coolant Pumps are manually tripped prior to leaving the Control Room, if possible, or locally from the Reactor Trip Switchgear, Turbine front standard, and 6i9KV Switchgeari A heat sink is provided by automatic steam dump to the Condenser and/or to atmosphere Level is maintained in the'S/Gs by manual control of auxiliary feedwater valves with flow furnished by the AFW Pumps~ Pressurizer level and pressure are maintained by manual control of Pressurizer heaters, auxiliary spray valves, and letdown valves, and are monitored at the Hot Shutdown Panel+
Isolation switches located in the Reactor Auxiliary Building Electrical Equipment Room, Turbine Building Switchgear Room, Diesel Generator Rooms, and Reactor Auxiliary Building are manually selected to the ISOLATE position to prevent inadvertant operation of vital equipment due to possible electrical malfunction in the unattended Control Room A copy of this procedure will be posted at each manned operating station required for plant shutdown from outside the Control Room~ A listing of isolation switches will be posted on each of the following panels, MCCs, and distribution buses Load Centers lA2, 1B2, 1A5, 1B9, lAB, 1A6, 1B6 2~ Isolation Panels lA, 1B, IAB 3~ MCC lA5, 1A6, 1B5, 1B&
