Turnover: Unit was down powered due to an oil leak on the 2B Main Feedwater Pump. Oil leak has been repaired and the 2B Main Feedwater Pump was just started. 2A AFW pump has been DOS for four hours, expected to be returned to service in one hour. The crew is to perform an up power to 100%.

Scenario Event Description NRC Scenario I St. Lucie The Unit will be turned over to the Crew at 45% power. 2C Charging Pump is out of service for repack.
Both Main Feedwater Pumps are running and the Crew is to perform an up power to 100%.
During the up power the DEH system will swap to Turbine manual. No alarm is annunciated with this failure. The up power is to be conducted with the Turbine in manual control.
As the up power progresses, the non-selected Pressurizer level controller LIC-1 11 QY fails low. All heaters will be lost, the B side 4.16 Pressruizer heater breaker tripping open and unable to be re-closed. Key #98 will be required to be taken to the level position to regain only the A side Pressurizer heaters. SRO is to evaluate T.S. on loss of heaters. (T.S. 3.4.3)
Containment Cooler HVS-1C trips and is not recoverable. Containment cooler HVS-1D will not start. The Crew is required to monitor Containment temperature to ensure temperature is maintained less than 120°F. SRO is to evaluate T.S. on loss of one train of Containment cooling. (T.S. 3.6.2.1)
H IC-i 110 Letdown controller fails causing full letdown flow. The RO is to take manual control of the letdown flow controller to re-gain control of letdown flow. When flow control is re-gained, the letdown line in the containment will leak resulting in a SBLOCA. Pressurizer level will not be maintainable and the Crew should manually trip the Unit.
Upon Unit trip the B side will not swap to the SU transformers and the 2B Diesel will not automatically start. The SNPO will be required to locally start the 2B Diesel Generator.
Upon the Unit trip the 2A MFW recirc. valve will not open. This will result in the 2A MFW tripping on low flow. Eventually AFAS will actuate but MV-09-1 1 2C AFW to 2A SG does not open. MV-09-12 2C AFW to 2B SG opens to 70 gpm flow but then the valve motor breaker trips. 28 AFW pump does not start on AFAS but can be manually started. AFAS lockout will occur on the A side due FW pressure when B side pressurizes. Due to the small break LOCA this scenario makes starting the 2B Diesel and restoring feedwater critical.
2-EOP-03, LOCA should be implemented to mitigate the small break (150 gpm) from the letdown line. If the crew has difficultly establishing feedwater they may elect to enter 2-EOP-15, Functional Recovery which is acceptable but may delay the recovery actions. The scenario may be terminated when feedwater is restored to at least one SG, the RCS is being cooled down and depressurized while maintaining subcooling.

Scenario Event Description NRC Scenario 2 St. Lucie Unit is at 100% power with 2A AFW pump OOS to repair an oil leak. It is expected to be back in service within one hour. The 2C Charging pump is out of service for repack.
The 2A Heater Drain Pump has a severe shaft seal leak and must be removed from service. The crew will perform a down power to approximately 90% to remove the pump from service.
Boric Acid flow control valve FCV-2210Y fails closed and cannot be opened. The crew will implement the Off Normal procedure and use the emergency borate valve to continue the down power.
During the down power the 2A Charging pump will trip on low oil pressure. The SRO will need to make a T.S. 3.1.2.4 & 3.5.2 a2 calls due to one Charging pump operable. If the crew has not started the 2B Charging pump for the down power, procedure requires letdown to be isolated. Charging and Letdown ONP should be implemented and Charging and letdown should be placed back in service if secured. If 2B Charging pump was started prior to the loss of 2A Charging pump, letdown bias will need to be adjusted to maintain Pressurizer level on setpoint.
As the down power progresses the 2A DEH pump trips. The 2B DEH pump does not automatically start and should be manually started.
Containment Pressure PT-07-2B fails high. The SRO should refer to T.S. 3.3.1 and 3.3.2 and implement ONP for loss of Tech. Spec. Instrumentation.
A major steam leak in the Containment will develop. The crew should manually trip the Unit prior to any automatic trip. As the leak progresses and a MSIS is received the 2B MSIV does not close. The MSIV can be closed manually from the Control Room.
AFAS lockout will occur but the 2B AFW pump will continue to feed the faulted S/G through MV-09-10.
The crew should manually terminate AFW flow to the 2B S/G by stopping the 2B AFW pump.
Implementation of 2-EOP-05 Excess Steam Demand should be implemented. Termination of scenario should be when the 2B S/G is isolated lAW 2-EOP-99 Appendix R and RCS temperature and pressure are under control.

NOTE
- The purpose of placing the Pressurizer on recirculation is to keep the Pressurizer and RCS boron concentration within 25 ppm when changing RCS boron concentration.
- From measured data, the estimated time in minutes to correct a greater than or equal to 25 ppm boron mismatch by operating 6 Backup Heater Banks may be determined as follows:
- Time (in mm.) to correct mismatch = [(Pzr ppm - RCS ppm) -
25ppm]x3
- 1. To place the Pressurizer on recirculation:
A. PLACE all available Backup Heater Bank control switches to ON.
B. Slowly REDUCE the AUTO setpoint on PlC-i 100X or PlC-i bOY, the selected Pressurizer Pressure controller, to maintain normal operating pressure.
C. OBSERVE HIC-1100, Pressurizer Spray output and PCV-1100E / hOOF, Pressurizer Spray Valve position indication to verify Main Spray flow.
NOTE Normally, the required number of Backup Bank heaters in service is dependent upon:
- 1. The magnitude of thermal losses from the system, including leakage to the Quench Tank.
- 2. The number of heater elements out of service.
The normal configuration is to have enough Backup Bank heaters in service to keep the Proportional Bank heaters at approximately 50% output.

ST. LUCIE PLANT QPS-539 OPERATIONS DEPARTMENT POLICY Rev. I Date 06/02/09 RCS COOLDOWN GUIDANCE Page lof2 THIS POLICY HAS BEEN COMPLETELY REWRITTEN The purpose of this guidance is to precisely control the plant during RCS cooldowns.
The limit, at which the RCS is cooled, is determined by the plant configuration (e.g., RCPs in operation, number of SOs available, status of subcooling, etc). The method of cooldown will be determined by the availability of condenser vacuum, SBCS, ADVs, and Safety Injection flow rate. When cooling down the RCS:
The US will:
- 1. Direct the RCO to commence a cooldown of the RCS using ADVs or SBCS.
- 2. Give the RCO a limit (e.g., Do not exceed 100°F in any one hour period).
The RCQ will:
- 1. Document RCS T-cold (the starting point will always be 532°F post trip). Document and report RCS T-cold and cooldown rate to the US every 10 minutes.
- 2. Commence a cooldown of the RCS. Ensure that the limits of Figure 1A or 1 B are being restored or maintained.
- 3. Using SBCS for recovery of subcooling or during a Steam Generator Tube Rupture cooldown to T-hot less than 510°F:
- a. Place the SBCS in manual operation.
- b. Fully open PCV-8801. If PCV-8801 is unavailable, use the next available SBCS valve.
- 4. Using ADVs for recovery of subcooling or during a Steam Generator Tube Rupture cooldown to 5 10°F:
- a. Place an ADV on each Steam Generator in service, preferably in Auto-Manual (if available) or Manual-Manual.
- b. For Unit 1, open the ADV on each Steam Generator to 50% open.
- c. For Unit 2, fully open one ADV on each Steam Generator.
46
ST. LUCIE PLANT OPS-539 OPERATIONS DEPARTMENT POLICY Rev. I Date 06/02/09 RCS COOLDOWN GUIDANCE Page 2of2
- 5. Once subcooling is restored or the cooldown limit is being approached, adjust the position of the ADVs or SBCS to ensure that the cooldown limit-will not be exceeded.
The objective here is not to cool down 100°F in a few minutes and then stop the cool down for the remainder of the hour. After the initial opening, ADVs or SBCS should be adjusted to achieve a rate of 100°F/hour, based on each 10 minute plot. Continued lowering of steam flow may be necessary if ECCS flow is present. If after the first 10 minutes the rate is still >100°F/hour, then adjust ADVs or SBCS to 75% open.
If after the next 10 minute plot it is still >100°F/hour, then adjust ADVs or SBCS to 50%
open and so on until a balance is achieved between steaming and ECCS flow.
If ECCS flow alone in contributing to RCS cool down at >100°F/hour, then steaming should be secured.
- 6. Once 510°F T-hot is reached for a Steam Generator Tube Rupture cooldown, adjust the position of ADVs or SBCS to ensure that the cooldown limit will not be exceeded.
The RCS temperature will be stabilized when the Excessive Steam Demand has terminated, or the Steam Generator has blown dry.
The US will:
The RCO will:
- 1. Determine the saturation pressure for the lowest RCS T-cold (if this wasnt performed prior to dry-out, the ADV[s] will be opened first then the saturation pressure will be determined).
- a. For Unit 1: open the ADV on the non-faulted Steam Generator to 100% open, in manual, then adjust the auto setpoint to the saturation pressure for the lowest RCS T-cold and place it in auto.
- b. For Unit 2: open one ADVs on the non-faulted Steam Generator tolOO% open, in manual, then adjust the auto setpoint to the saturation pressure for the lowest RCS T-cold and place it in auto. Open the second ADV on the non-faulted Steam Generator to 100% open, in manual, then adjust the auto setpoint to the saturation pressure for the lowest RCS T-cold and place it in auto.

Scenario Event Description NRC Scenario 5 St. Lucle The unit will be turned over to the crew at 30% power. The 2B Main Feedwater Pump is out of service to replace the oil cooler, The crew will increase power to approximately 45%.
A loss of the 2B Component Cooling water pump will require the crew to swap the AB electrical to the B side to take T.S. credit for the 2C Component Cooling water pump.
Selected Pressurizer Level LT 111 OX fails high requiring the RO to swap level channels.
Acoustic monitor for PORV 1474 wIll annunciate and fall high. The crew will determine this failure Is only Instrument failure and not a leaking PORV. The SRO is to evaluate T.S. for accident monitoring.
A loss of the 2A Sups Vital bus Inverter will occur during the up power. Numerous secondary alarms and loss of instrumentation will occur. The alternate dump valves on the heaters will open in addition to loss of DEH turbine control. The Vital bus can be re-energized from the alternate source. Plant stabilization will be required due to secondary perturbation.
A LOOP combined with a loss of feedwater will occur. The 2B Diesel will not start and the 2A Diesel output breaker will not close. The output breaker can be closed from the RTGB. The 2C AFW pump will trip on AFAS or manual start and cannot be restarted. The 2A AFW pump MV-09-9, 2A AFW pump to 2A SG, will not open. The crew is expected to crosstle the 2A AFW pump to feed the 2B SG.
The Crew will probably enter 2-EOP-09. LOOP, LOFC prior to entering 2-EOP-06 due to AFAS-2 actuating approximately 15 mInutes after the trip and AFAS-1 actuating approximately 20 minutes after the trip.

Scenario Event Description NRC Scenario 8 St. Lucle UnIt 2 The crew assumes the shift at 2-3% power. The 2C Charging pump is out of service to replace shaft seals. The crew will be instructed to raise power and place the unit on line.
Shortly after turnover, CIS RM-26-4-2 fails high. This is a T.S. SRO call and the channel must be bypassed lAW 2-ONP-99.01.
As the RO is withdrawing CEAs one CEA In the group will not move. I/C should be notified to investigate.
The individual CEA movement issue will be resolved and that CEA will be realigned with its group. If the CEA movement issue is not noticed prior to misaligned greater than 7 inches this should be a T.S. call.
A spurious opening of the 2A2-2A3 Tie Breaker will cause the 2A3 4.16KV bus to de-energize. As designed, the bus will be de-onergtzed for about 10 seconds and then the 2A Diesel Generator closes onto the bus. The spurious opening of the tie breaker will be resolved and the breaker will be manipulated to parallel with the gild. When the 2A3 bus is tied back to the grid, the 2A Diesel Generator will be shut down. When 2A3 bus Is reenergized, MCC 2A8 will fail to energize (not required for scenario). This will require a Tech Spec call by the SRO. MCC 2A8 can be re-energized after the Tech Spec call. Pressurizer heaters, charging and letdown will have to be restored. Additional manipulations of the SBVS, CR ventilation and SBCS DCS input will also have to be manipulated (not necessary to continue).
CCW header B will rupture causing the surge tank to lower. The N header should Isolate, however HCV 14-10 falls to close. The Operator should recognize this and manually close HCV-14-10. CCW can then be restored to the RCPs via the A header.
A SGTL occurs on the 2B Steam Generator followed by a SGTR. This will require a Reactor shutdown.
When the unit is tripped a Main Steam Safety valve on the 2A Steam Generator opens and fails to close until 500 psia steam pressure on the generator. MSIS fails to actuate at 700 psia and must be manually actuated. The crew should exit EOP-01 to EOP-15 due to a dual event (ESD and SGTR). NOTE:
Operations management written guidelines state if a MSSV falls to reseat when designed the Steam Generator Is considered faulted until the MSSV is gagged.
Upon SIAS the 2A HPSI pump fails to start. It can be manually started. This is a critical step due to the rupture of the B CCW header, the 2B HPSI pump is considered inoperable.
The exercise can be terminated when the 2A Steam Generator is isolated. A cool down is in progress using the 26 Steam Generator.

INSTRUCTIONS CONTINGENCY ACTIONS CAUTION If there is a conflict between isolating a S/G with indications of SIG tube leakage or isolating a S/G with an unisolable steam leak, Then the S/G with the ESD should be isolated. At least ONE S/G must remain available for heat removal.
El 2. Determine If SGTR Present If a SGTR has occurred as indicated by ANY of the following,
- SIG activity
- Main steam piping radiation
- SIG level change when NOT feeding
- SIG blowdown activity
- ONE SIG level rising faster than the other with feed and steaming rates being essentially the same for BOTH o Feedflow mismatch between S/Gs
- Steam flow vs. feed flow mismatch in a S/G PRIOR to the trip Then IDENTIFY and ISOLATE the MOST affected SIG.
