NOT OBTAINED NOTE:
o If either ECA-3.2, SGTR WITH LOSS OF REACTOR COOLANT - SATURATED RECOVERY DESIRED or ES-1.3, TRANSFER TO COLD LEG RECIRCULATION is in effect, this procedure should not be performed.
o 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 RHR Normal Cooling-NOT IN SERVICE Refer to AP-RHR.l, LOSS OP RHR.
2 Check RWST Level GREATER THAN 284 Ensure SI system aligned for cold leg recirculation using Steps 1
through 13 of ES-1.3, TRANSPER TO COLD LEG RECIRCULATION.
3 Verify SI Flow:
a.
SI line loop A and B flow indicators -
CHECK POR PLOW b.
RCS pressure
- LESS THAN 250 psig [465 psig adverse CNMT]
c.
RHR loop flow indicator -
CHECK POR PLOW
- a. Manually start SI pumps and align valves.
b.
Go to Step 4.
- c. Manually start RHR pumps and align valves.

RESPONSE
NOT OBTAINED CAUTION IF ANY PRZR PORV OPENS BECAUSE OF HIGH PRZR PRESSURE, IT SHOULD BE CLOSED AFTER PRESSURE DECREASES TO LESS THAN 2335 PSIG (REFER TO STEP 4b).
4 Check PRZR PORVs And Block Valves:
a.
Power to PORV block valves-AVAILABLE b.
PORVs -
CLOSED
- a. Restore power to block valves unless block valve was clo'sed to isolate an open PORV:
~ MOV-515, MCC C position 6C
~ MOV-516, MCC D position 6C
- b. IF PRZR pressure less than 2335 psig, THEN manually close PORVs.
IF any PORV can NOT be closed, THEN manually close its block valve.
- c. Block valves - AT LEAST ONE OPEN d.
Rx vessel head vent valves-CLOSED c.
Open one block valve unless it was closed to isolate an open PORV.
- d. Manually close valves.
