- 3. The OATC is controlling SIG levels and the steam dumps for the cooldown.
INITIATING CUES:
- 1. The CRS instructs you to depressurize the NC system to 1905 PSIG and to block the low steam pressure Main Steam Isolation signals and the pressurizer low pressure Sit signals per steps 10 and 11 of ES-0.2. The CRS asks you to ensure you are maintaining NC pressure under your control.

UNSAT LI I NC-29 (Pzr Spray Ctrl Frm Loop B)
LI I NV-39A (NV Supply To Loop D Isol)

Applicant determines that valve controllers for 1 NC-27 and 1 NC-29 show 0% demand. Applicant determines that INV-39A green CLSD light is lit and red OPEN light is dark. Applicant determines that 1 NV 32B green CLSD light is dark, and depresses the green CLOSE pushbutton and verifies the green CLSD light is lit and red OPEN light is dark.
This step is critical because all the valves listed need to be closed to use NV aux spray.

STANDARD:
SAT Applicant depresses the red OPEN and green CLOSE pushbuttons as UNSAT necessary to throttle I NV-37A to depressurize the NC system..
Applicant monitors pressUrizer pressure decreasing toward 1905 PSIG.
This step is critical because INV-37A must be throttled open in order to decrease primary system pressure.
COMMENTS:
CAUTION if PZR pressure increases to greater than 1955 PSIG, then Main Steam Isolation and PZR low pressure SII circuits will automatically unblock.
