NOT OBTAINED NOTE:
Adverse CNMT values should be used whenever CNMT pressure is greater than 4 psig or CNMT radiation is greater than 10-
~ R/hr.
1 Check SI Pumps ALL STOPPED Return to procedure and step in effect.
2 Verify Normal And Excess Letdown Isolation Valves CLOSED Manually close valves.
~ Letdown orifice valves (AOV-200A, AOV-200B, and AOV-202)
~ Loop B cold leg to REGEN Hx (AOV-427)
~ Excess letdown isolation valve (AOV-310) 3 Reset CI:
- a. Operate CI reset key switch
- b. Verify annunciator A-26, CNMT ISOLATION - EXTINGUISHED
- b. Perform the following:
- 1) Reset SI.
- 2) Operate CI reset key switch.

NOT OBTAINED 4 Verify Adequate SW Flow:
a.
Check at least two SW pumps-RUNNING
- b. Dispatch AO to establish normal shutdown alignment (Refer to Attachment SD-1)
- a. Manually start SW pumps as power supply permits (258 kw each).
IR less than two SW pumps
- running, THEN perform the following:
- 1) Ensure SW isolation.
- 2) Dispatch AO to establish normal shutdown alignment (Refer to Attachment SD-1) 3)

- a. Verify non-safeguards busses energized from offsite power o
Bus 13 normal feed -
CLOSED a.
Perform the following:
- 1) Close non-safeguards bus tie breakers:
-OR-o Bus 15 normal feed - CLOSED
- b. Verify SW isolation valves to turbine building - OPEN
~ 'MOV-4613 and MOV-4670
~ MOV-4614 and MOV-4664
~ Bus 13 to Bus 14 tie
~ Bus 15 to Bus 16 tie 2)
WHEN bus 15 restored, THEN reset control room lighting.
- b. Manually align valves.
- c. Verify at least two air compressors
- RUNNING
- d. Check IA supply:
o Pressure
- GREATER THAN 60 PSIG o
Pressure STABLE OR=-
INCREASING
- c. Manually start air compressors as power supply permits (75 kw each).
IF air compressors can NOT be started, THEN dispatch AO to locally reset compressors as necessary.
- d. Perform the following:
- 1) Continue attempts to restore IA (Refer to AP-IA.1, LOSS OF INSTRUMENT AIR).
- 2) Continue with Step 6.
WHEN IA restored, THEN do Steps 5e and f.

Establish Charging Flow:
- a. Charging pumps - ANY RUNNING
- b. Align charging pump suction to RWST:
o LCV-112B -
OPEN o
LCV-112C -
CLOSED
- a. Perform the following:
- 1) IF CCW flow is lost to any RCP thermal barrier OR any RCP gl seal outlet temperature offscale high, THEN dispatch AO with RWST area key to locally close seal injection needle valves to affected RCP.
~ RCP A, V-300A
~ RCP B, V-300B
- 2) Ensure HCV-142 demand at OX.
- 3) Start one charging pump.
- b. IF LCV-112B can NOT be opened, THEN perform the following:
- 1) Verify charging pump A NOT running and place in PULL STOP.
- c. Charging flow - ESTABLISHED
- 2) Dispatch'O to locally open manual charging pump suction from RWST (V-358 located in charging pump room).
3)
WHEN V-358 open, THEN direct AO to close V-268 to isolate charging pumps B and C from VCT (V-268 located in charging pump room).
- c. Start additional charging pumps as necessary.

Increase Charging Flow To
- Restore PRZR Level IP charging flow at maximum, THEN manually operate SI pumps as necessary.
IP PRZR level can NOT be restored, THEN go to E-l, LOSS OF REACTOR OR SECONDARY COOLANT, Step l.
8 Check PRZR Level:
- a. Level - INCREASING
- b. Level - GREATER THAN 13X [40X adverse CNMT]
- a. Return to Step 7.
- b. Return to Step 8a.
