CVCS Letdown may be controlling Pressurizer level between 25% and 50%.
d.
Train B Component Cooling System may be in service, e.
Pressurizer heaters may be controlling Pressurizer pressure between 2200 psig and 2300 psig.
CAUTION 3.0 in the event of an emergency not covered by an approved written pro:edure, I operating personnel have the authority to take action to minimize personnel injury or damage to the facility and to protect the public health and safety. Such actions shall be documented by the operating personnel.
i NOTE 3.0 l l
a.
! If any electrical component will not operate from the specified location, attempts should be made to control it per Attachment Vill, IX, X, or XI.
b.
Due to the potential for electrical shorts due to fire, each component that is operated remotely should be checked periodically to ensure that i
it is in the desired position, c.
During the cooldown phase, attempts to repair support equipment will continue. This procedure was written for the worst case. If control of a piece of equipment is regained from the Main Control Board or Motor L
! Control Center, it may be operated from that location utilizing the proper attachment.
i 3.0 OPERATOR ACTIONS 3.1 l Monitor LI-3631 A, CST LEVEL, and fill the CST when needed as follows:
I a.
If power is available to XMC1 A4X, fill the CST from Domineralized Water per SOP-208, Condensate System.

FEP-3.1 ATTACHMENT XI PAGE 1 OF 2 REVISION 3 REMOTE OPERATION OF VALVES FROM 480V MOTOR CONTROL C NOTE 1 MVG-8133B is a Power Lockout valve. Power Lockout valves require both Power Lockout and Valve Motor starter relays to be actuated simultaneously fo remote operation. MVG-81338 starter relays are located in XMC1DB2Y 06EH and XMC1DB2Y 15CD.
1.
Locate the Motor Control Center Cubicle (s) for the valve to be operated.
2.
Position the breaker (s) to OFF(RESET).
- 3. Open the cubicle door (s).
4.
Remove the control power fuse for motor starter with fuse pullers.
5.
Locate the two motor starter relays in the appropriate cubicle.
6.
Place a clamp-on ammeter around one of the following:
a.
One heavy wire connected between the top of the motor starter relays and the circuit breaker,
- b. One field motor lead.
7.
Perform Step 7.a for digital ammeters or Step 7.b for analog ammeters as follows:
a.
When using digital ammeters, perform the following:
- 1) Ensure switch on face of meter is in C posrtion.
- 2) Depress and hold the red pushbutton on the meter side.
- 3) Verify the display lights up. i
- b. I When using analog ammeters, perform the following.
- 1) Ensure meter pointer is unloclw tswitch to left).
- 2) Set Meter Scale to 0-6A.
FEP 3.1 ATTACHMENT XI PAGE 2 OF 2 REVISION 3 8.
Close the circuit breaker (s).
9.
If applicable, actuate the Power Lockout relay contactor and hold.
l l
l NOTE 10 a.
Starting current for large valves may cause the ammeter to indicate full l scale. Current should stabilize on scale within one to two seconds the nominal value of running current listed for the valve on Attachment Xill.
I
- b. While the motor is running, the meter will read low.
c.
When the valve is at the end of its travel, the motor stalls at close to five times its running current.
10.
Actuate the desired motor starter contactor (left contactor to close the val right contactor to open the valve) by depressing through the appropriate slot with a screwdriver blade.
11.
Observe current on the ammeter for the following:
a.
If current remains high, release contactor; valve is in the required position already. ;
b.
If low, release contactor when current begins to rise sharply.
12.
If applicable, release the Power Lockout relay contactor.
- 13. Re-open the circuit breaker (s).
14.
Remove the ammeter and close the cubicle door (s).
