Allow speed on MFP B to decrease (if SIC-509C is in auto) or decrease speed demand (if SIC-509C is in manual).
(2) Continue to lower speed on MFP B until the vibration alarm clears or 5100 rpm is reached.

- Reduce Turbine Load at approximately 3% RTP per minute (approx 36 MWe) up to 5% RTP (approx 60 MWe).
- Borate AFD within the doghouse.
- All rod withdrawals will be approved by the SS.
- Approval for each reactivity is not necessary as long as manipulations are made within the boundaries established in this briefing (I.e. turbine load adjustment up to 60 MWe, etc.
- A crew update should be performed at approximately every 100 MWe power change.
- If manpower is available, peer checks should be used for all reactivity changes.
OPERATIONAL LIMITS
- Maintain Tavg within +/- 6°F of Tref. IF TAVGfTREF mismatch >6°F and not trending toward a matched condition or if Tavg ~ 551°F, then trip the reactor.
- If load reduction due to a loss of vacuum, every effort should be made to maintain the steam dumps closed. (Permissive C-g ~24.92" Hg).
INDUSTRYOE
- Shift supervision must maintain effective oversight and exercise conservative decision making.
- Correction of significant RCS Tavg deviations should only be via secondary plant control manipulations and not primary plant control manipulations (i.e., do not withdraw control rods or dilute).

Time Position Applicant's Action or Behavior SS Enters 19011-C, ES-1.1 SI Termination.
OATC 1. Initiate the following:
UO
- Continuous Actions and Foldout Page .
- Critical Safety Function Status Trees per 19200-C, F-O CRITICAL SAFETY FUNCTION STATUS TREE.
SS 2. Initiate NMP-EP-110, EMERGENCY CLASSIFICATION AND DETERMINATION AND INITIAL ACTION.
CREW CAUTIONS If offsite power is lost after SI reset, action is required to restart the following equipment if plant conditions require their operation.
- RHR Pumps
- SI Pumps
- Post-LOCA Cavity Purge Units
- Containment Coolers in low speed (started in high speed on a UV signal)
- ESF Chilled Water Pumps (If CRI is reset)
OATC 3. Reset SI.
OATC 4. Verify only one CCP - RUNNING.
Note to examiner: It is expected both CCPs will be running, usually the crew will stop CCP A.
