- 6. 0 DISCUSSION This procedure is designed to shutdown the plant from outside the Control Room by using the Remote Shutdown Panel and/or manual oper'ations in the plant.
Activation of the Remote Shutdown Panel transfer switches bypass the Main Control Room devices and transfer the components control power to alternate supply or thru new fuses.
This transfer should be made prior to manual operation of system because most auto signals to these systems are bypassed.
x Evacuation of the Main Control Room should only occur after reasonable efforts have been utilized including use of respiratory equipment.
Upon
-leaving the Control Room, the Reactor shall be scrammed and the MSIVs and main steam line drains closed.
All other functions shall take place outside the Control Room.
An Operator/STA should be stationed at the TSC to monitor plant parameters on DCS/PMS and SPDS.
He should be equipped -to communicate with the Remote Shutdown Panels.
If the TSC is also uninhabitable, he should go to the EOF and establish communications to the Remote Shutdown Panels.
RCIC system shall be utilized to control Reactor water level. If RCIC is unavailable HPCI should cycle automatically to provide adequate core cooling.
Reactor pressure shall be controlled with the Safety/Relief Valves.
As pressure increases to a relief set point, the valve will open with the exception of the three relief valves controlled from the Remote Shutdown Panel.
Mhen these three valves are transferred,to the EMERG position, their relief function is bypassed.
These valves will only auto open off their safety setting.
All other valves will open off their safety setting only if their relief function is inoperable.
If pneumatic supply is unavailabl'e to SRV's from Remote Shutdown
- Panel, ADS valves can be operated individually from Upper or Lower Relay Rooms using keylock switches.
RHR-Suppression-Pool Cool.ing shall-be used to maintain the suppression
.pool less-than-maximum-design temperatures.
The~other loop of RHR can be:.
manually operated if the loop normally, controlled on the remote shutdown panel 'is unavailable.

and/or-HPCI-opei ati on.
l In bringing the plant to cold shutdown',
the three (3) Safety/Relief Valves on the Remote Shutdown Panel shall be used sequentially to distribute heat load (not exceeding 100'F/hr cooldown rate) until pressure is low enough to establish RHR Shutdown Cooling.
If RHR Shutdown Cooling i's unavailable, cooling can be accomplished using the alternate cooling method per ON-149-001 from outside the Control Room.
