State RCP trip Requirement during a SD LOCA (include adverse containment numbers)
PZR level <7% (28% if adverse) - OR - RCS subcooling <40F - OR - RCP seal DP <220# - OR - RCP seal leak off less than required
State Mode 4 T.S. action Statement for loss of ECCS
With no ECCS subsystem OPERABLE because of the inoperability of either the centrifugal charging pump or the flow path from the refueling water storage tank, restore at least one ECCS subsystem to OPERABLE status within 1 hour or be in COLD SHUTDOWN within the next 20 hours.
State Rx trip criteria for loss of SCCW
If at least one pump can not be started then trip the Rx
State how to control SCCW pump amps when on 1 pump
Throttle the running pump discharge valve
State Rx trip criteria for loss of IA
If a loss of plant control occurs then trip the Rx
State when SA header can be restored
When SA # is >95# then open SA-V-92/93
State entry to GSU Trouble
ISO NE notifies Seabrook of a Kp7 or higher
Florida TPDC notifies Seabrook of a Kp7 or higher (TPDC will notify at a 6 but entry is not required)
State GSU trouble Rx trip Criteria
Hot spot winding temp >110C and GSU oil temp alarm limit is exceeded
- OR -
DC Neutral Ground Current limit is exceeded
State Load reduction Criteria for GSU trouble
Hot Spot Winding Temp >100C
- AND -
GSU Oil Temp High reset

State Rx trip Criteria on high SG pressure
1150#
State actions if H2 pressure is not normal and seal oil pumps are not working
Trip Rx (turbine)
State indications of CBS check valves leakage
Suction pressure/temp high
High heat up rate in suction line (6F/min = gross failure)
State NRC notification for loss of RHR cooling
8 HRs per 10 CFR 50.72
State alternate method for sweeping air out of lines in the RHR system
fill vessel above -71”
Run a RHR pump at greater than 2285 GPM
State vessel level where a RHR pump can be started
-83.5” and stable or rising
State the rate of decrease for cavity level if the seal is leaking
2”/min with transfer valve closed
- OR -
1”/min with transfer valve open
For a loss of SF pool level state the preferred order of make up
Gravity feed from the RWST
Gravity Feed from CST
Fire Protection
State normal level of SFP and Bottom of skimmer
Normal: 25.4’
Bottom: 25.1’
State caution for restoring SFP cooling during an ECCS actuation
If in ECCS recirc mode with only 1 train the PCCW system may be 120F and restoration to the SFP should be delayed for up to 4hrs
State basis for having CRFRM
Keep the CR <5Rem to CROs for up to 30 days
State EFW TS 3.7.1.2 action d
With three auxiliary feedwater pumps inoperable, immediately initiate corrective action to restore at least one auxiliary feedwater pump to OPERABLE status as soon as possible.
State Rx trip criteria for Turbine Building Flooding
If water level can not be maintained below the grating --> Trip the Rx When immediate actions are complete --> Place all CW pump CS in PTL Close MSIVs and bypass valves
State required rate of down power in Turbine building flooding
25%/hr
State required SW flow to EDG HX
900GPM on ocean
1800 GPM on CT
State Rx trip criteria for degraded vital AC
If power can not be restored to at least one AC Bus –> trip the Rx Go to ECA-0.0
State impact on plant control on a loss Vital DC Bus
Remote control capability is removed, local action is required
State HELB alarm set point
120F
State HELB Valves

Per OP 9.2 state what NOTES do
NOTES contain administrative or advisory information which supports operator action
Per OP 9.2 state what CAUTIONS do
CAUTIONS contain information about potential hazards to personnel or equipment. They also advise on actions or transitions which may become necessary depending on changes in plant conditions
State operator action on a status tree orange or red path
indications should be validate using hardwires
State direct entry into the EOPs
