- '., WP2760P 0-0055P C.13A HOT SHUTOOWN FROM SHUTDOWN PANEL WITH A FIRE IN THE CONTROL ROOM i
1.0 SYMPTOMS 1
.1 1 Control Room becomes untenable due to a fire in the Control Room.
) .2 Off-Site power may or may not be available.
i l
1 2.0 RESPONSE NOTE:
The methodology used in this procedure is patterned after the Abnormal Transient Operating Guidelines
( ATOG) for a loss of of f-site power. The objective of this procedure is to prevent overcooling of the RCS, establish inventory control, and establish primary to secondary heat transfer. The major
.('
L operator actions are:
- a. De-energize the EMOV PSV-21511.
.j c. Establish AFW to "B' OTSG.
Then reestablish feed 3 to "A" OTSG.
1
- e. Reestablish plant air.
! f. Assure main steam isolation.
- g. Isolate and start the Diesel Generator as required.
Once these steps are performed, RC Pump Seal Injection will be established. This will assure control over the plant.

NOTE: -
The Senior Control Room Operator directs shutdown of the plant from the Shutdown Panel (H250) and serves .
as the central point for communications with all operators.
( .1 Direct an operator to the 480 Volt West Switchgear Room to perform Enclosure 4.4. He will act as the Control Operator. -

.5 Commence Enclosure 4.8, Senior Control Room Operator Sign-Off Sheet.
.4 Control Room Operator:
NOTE:
The Control Operator deenergizes the EMOV, CRO, and I -
4160 Volt equipment necessary to achieve hot l7g~ ~
shutdown and deenergizes the unnecessary 4160 Volt equipment.
, .1 Evacuate the Control Room.
.2 Proceed to the 480 Volt West Switchgear Room.

.8 Shift Supervisor information:
$ This section is intended to provide the Shift Supervisor with additional J information and reminders and does not contain any mandatory actions for j shutdown of the plant.
j .1 HPI Cooling 1
j This procedure is based on cooling the plant through natural circulation cooling. If high pressure injection cooling were 1 needed or if the "A" HPI pump fails, the Makeup Pump can be f
transferred to the "A" power train a'id operated from the shutdown panel. An operator would need to be sent to the Makeup Pump area
, to position the selector switch and line up cooling water in i accordance with A.15 " Makeup, Purification, and Letdown System.".
