Diesel Generators - Manual Operation of DG 1-3 OP J-6B:VI R35 Page 3 of 20 UNIT 1
- 5. PRECAUTIONS AND LIMITATIONS 5.1 Paralleling the DG to startup power defeats both second level UV relays. REFER TO TS 3.3.5.
5.2 REFER TO the following for DG 1-3 operability requirements:
- TS 3.8.3, "Diesel Fuel Oil, Lube Oil, Starting Air, and Turbocharger Air Assist"
- STP M-9A3, "Diesel Engine Generator 1-3 Routine Surveillance Test" 5.3 When ANY of the following conditions exists, DG 1-3 is declared INOPERABLE and the appropriate TS actions are performed:
- Paralleling DG 1-3 to any off-site power source
- DG 1-3 Mode Sel switch is in "MANUAL" AND DG 1-3 is NOT running NOTE: Extended operation of DG 1-3 below 0.65 MW can expose the engine to undesirable conditions that may be detrimental to engine performance and component life.
5.4 DG 1-3 should not be operated for extended periods (one hour or longer) below 0.65 MW:
- If DG 1-3 is operated below 0.65 MW for at least one hour but less than ten hours, then the DG should be operated at or above 1.30 MW for at least one hour.
- If DG 1-3 is to be operated for more than ten hours at or below 0.65 MW, the DG should be loaded to at least 1.3 MW for more than one hour at the end of each 10-hour period.
5.5 Do not operate DG 1-3 below rated speed with the field energized. Excessive field currents and rotor temperatures may occur.
5.6 When paralleling DG 1-3, pick up load (0.50 MW) as soon as possible (less than 15 seconds) after the breaker is closed. This will prevent the DG breaker from tripping on directional power (DIR PWR).
5.7 There should be fuel oil in the priming tank. If not, it should be filled using the magnetic pump, and the problem documented in a notification.
5.8 The fuel oil pressure should increase to above 40 psig within 60 seconds of engine start.
Gauge response is about 15 seconds.
5.9 Normal shutdown of DG 1-3 requires DC control power. If shutting down DG 1-3 without control power becomes necessary, manually operate the trip lever on the northwest corner of the engine, forward of the fuel oil filters.

Diesel Generators - Manual Operation of DG 1-3 OP J-6B:VI R35 Page 4 of 20 UNIT 1 5.10 Do not violate the following limits during normal steady-state operation:
- Maximum continuous generator current: 451 amperes
- Maximum stator temperature: 240°F
- Minimum lube oil pressure: 60 psig
- Maximum lube oil temperature: 195°F
- Maximum jacket water temperature: 185°F
- Power factor: 1.0 to 0.8 lag
- Load: 2.60 MW at 0.8 power factor 5.11 Do not operate more than one DG at a time paralleled to any transformer (startup or unit auxiliary) in MODE 1, 2, 3, or 4. REFER TO SR 3.8.1.3, Note 3.
5.12 DGs are highly responsive to the starting of large motor loads, such as a 12kV pump, a condensate and booster pump set, or the No. 2 Heater Drain Pump. If the MVAR output is not reduced prior to starting such loads, a DG could exceed its kVA rating. If, while a DG is paralleled and at full load, a large motor load is to be started, first reduce MVAR output to 0.5 MVAR or less until after the load has been started.Ref 7.2 5.13 Prior to paralleling DG 1-3 to the bus, the DG 1-3 Mode Sel switch on VB4 shall be verified in "MANUAL".
5.14 Control power selection (EQD Panel):
- In MODES 1-4: DG 1-3 shall have its normal DC source energized and selected. If the backup source is selected, DG 1-3 is considered INOPERABLE and either DG 1-3 or 1-1 must be selected to MANUAL to prevent making Battery 1-3 INOPERABLE.
- In MODES 5, 6, and DEFUELED: Preferred alignment is for DG 1-3 to have its normal DC source energized and selected. If cross-tie capability exists (i.e., capability of supplying power to the battery charger aligned to DG 1-3 DC source), DG 1-3 and Battery 1-3 can still be considered OPERABLE with the backup source selected.
5.15 Day tank level columns respond very slowly to a level change. When manually filling the tank, use caution to avoid overflowing the day tank.
5.16 Crankcase exhausters should be operating while the engine is running. If not, DG 1-3 is still OPERABLE, but a notification shall be initiated and repairs made in a timely fashion. If crankcase exhausters are not running, DG 1-3 may experience more oil leakage from the block than normal.
5.17 If the lubricating oil temperature is below 90°F, DG 1-3 should not be started unless engineering has evaluated the condition.
5.18 Starting air header and turbo air header pressures should be monitored:

SCENARIO
SUMMARY
- NRC #1
- 1. Volume Control Tank (VCT) level channel LT-112 fails low, causing a continuous (and erroneous) makeup signal. The crew diagnoses the level channel failure by comparing other VCT parameters, and by using OP AP-19, Malfunction of the Reactor Makeup Control System. The makeup system is secured, and makeup is accomplished (if needed) using manual mode (or enabling the auto mode for short periods).
- 2. Auxiliary Building Supply Fan S-31 loses power and crew responds per AR PK15-17, AUX & FHB VENT PWR FAILURE. Auxiliary Building Ventilation System, ABVS, which was operating in Buildings and Safeguards, swaps to Safeguards only. Crew verifies automatic shutdown of Supply E-1 as well as auto-swap to Safeguards only alignment for the ABVS. Shift Foreman enters TS 3.7.12.B, Auxiliary Building Ventilation System (ABVS) for one ABVS train inoperable.
- 3. Steam Generator Header Pressure Transmitter, PT-507, fails high over 5 minutes causing actual temperature to lower. Crew identifies malfunction noting increase in steam flow and lowering Tcold, and takes manual control of HC-507. OP AP-5, Malfunction of Eagle 21 Protection or Control Channel is used to address the failure and return primary and secondary plant parameters to normal bands.
- 4. ASW Pump 1-1 trips due to a seized shaft. Standby ASW Pump 1-2 fails to start as the result of a fault at the breaker (SF6 pressure fault). The Shift Foreman implements OP AP-10, Loss of Auxiliary Salt Water and cross-ties to the Unit 2 ASW system via the ASW cross-tie valve FCV-601. Shift Foreman enters T.S.
3.0.3 for two trains of ASW inoperable on Unit 1.
- 5. An earthquake occurs, causing a 750 gpm leak to ramp in on loop 4 hot leg. The crew determines the leak is substantial in size based on a rapid drop in pressurizer level. The Shift Foreman directs a reactor and safety injection.
- 6. The crew enters EOP E-0, Reactor Trip or Safety Injection. Train B of Safety Injection fails to actuate, requiring the crew to perform numerous manual alignments and pump starts as part of Appendix E.
- 7. Charging Injection Supply Valve, CVCS-1-8803A fails to open on SI as well. The crew must open 8803A or its parallel equivalent, CVCS-1-8803B in order to meet the requirements of S1CT-1, Manually actuate at least one train of SIS actuated safeguards before transition out of EOP E-0.***
- 8. The seismic event damages the RWST, resulting in a large fissure that terminates close to the bottom of the tank. The crew briefly enters E-1, Loss of Reactor or Secondary Coolant prior to transitioning to E-1.3, Transfer to Cold Leg Recirculation when RWST level reaches 33%, which happens quickly due to the leaking RWST. With the Containment Recirc Sump Level less than 92%, the crew is forced into EOP ECA-1.1, Loss of Emergency Coolant Recirculation. The fissure location causes the RWST to continue to drain, requiring the crew to perform the second critical task S1CT2 - Stop ECCS pumps aligned to the RWST before insufficient level results in ECCS pump cavitation.***
The scenario is terminated once the crew has implemented Appendix W, RCS Makeup from VCT.

Note: The App G required minimum flow should be between 410-490 gpm, depending on how long the crew took to get here. The remaining CCP or the remaining SI pump will most probably not be capable of this flowrate (alone), so no pumps are expected to be shut down per step 16 RNO.

o (16.a) Checks RVLIS level and determines it is adequate based on number of running RCPs (SPDS screen).
o (16.b) Checks subcooled margin and determines it is NOT adequate; goes to RNO to reduce ECCS.
o (16.b RNO) Determines App G minimum flow requirement, based on time since trip (see above; most likely, can't shut down a pump).
o (15B RNO) Determines that stopping either the last CCP or SI PP will go below that minimum, and does not stop any pumps.

SCENARIO
SUMMARY
- NRC #2
- 1. Crew performs timed stroke test of SI Pump 1-1 suction valve 8923A per STP V-3L10A, Exercising Valve SI-8923A, Safety Injection Pump 1 Suction Valve. The valve strokes closed, but does not respond when the crew attempts to re-open it per the test procedure. The Shift Foreman notes already in Tech Spec for CCP 1-1 out of service. May contact Maintenance for assistance.
- 2. FT-128 (charging flow) fails low, causing actual charging flow to rise. The crew responds per OP AP-5, Malfunction of Eagle 21 Protection or Control Channel. FCV-128 and HC-459D are taken to manual, and charging flow is monitored using alternate indications (RCP seals, Pzr level, VCT level, etc) for the remainder of the scenario. OP AP-17, Loss of Charging, Section B (Charging System Equipment Malfunctions), may also be used to respond to the failure. TS 3.3.4.A, Remote Shutdown Systems, is implemented.
- 3. Accumulator 1-3 develops a 100 gpm leak, bringing in AR PK02-10, ACUM LEVEL HI-LO for level below 60.8%. Shift Foreman enters TS 3.5.1.B, Accumulators, when level falls below 52%.
- 4. A 120 gpm RCS leak on loop 3 ramps in over the next 3 minutes, requiring entry in OP AP-1, Excessive Reactor Coolant System Leakage. Pressure and level are stabilized once CCP 1-2 is started and letdown isolated. VCT level cannot be maintained at the current leak rate, however, and the crew determines a plant shutdown is required. Shift Foreman enters TS 3.4.13.A, RCS Operational Leakage.
- 5. CCP 1-2 trips and charging is no longer able to keep up with the leak. Shift Foreman directs a Reactor Trip and Safety Injection. The crew enters EOP E-0, Reactor Trip or Safety Injection and performs their immediate actions.
- 6. Loop 3 ruptures on the Safety Injection, with a 4.5 inch SBLOCA ramping in over the next 2 minutes.
- 7. Bus H is lost on a differential trip during the transfer to Startup and MDAFW Pp 1-3 fails to Autostart, leading to the critical task of starting MDAFW Pp 1-3 (S2CT-1) Establish at least 435 gpm AFW flow to the steam generators prior to exiting EOP E-0.***
- 8. SIP 1-2 is lost with the loss of bus H. Non-ECCS Charging Pump CCP 1-3 begins to cavitate and eventually trips, resulting in a total loss of all high and intermediate head injection. The crew proceeds through E-0, noting that RCPs must remaining running when pressure falls below 1300 psig due to a lack of running ECCS CCPs and SIPs. The crew determines the RCS is not intact and transitions to E-1, Loss of Reactor or Secondary Coolant. A loss of subcooling and lowering RVLIS level eventually results in a magenta path on the core cooling critical safety function, and the crew transitions to FR-C.2, Response to Degraded Core Cooling. Following the guidance of FR-C.2, the crew will perform the critical task of temporarily recovering the core:
(S2CT-2) Depressurize Steam Generators to inject SI Accumulators to re-flood the core before a RED path develops on Core Cooling Critical Safety Function.***
The scenario is terminated once Accumulators have injected enough volume to clear the MAGENTA path on CORE COOLING

- 4. Main Turbine Stop Valve #2 closes, causing a secondary transient, bringing PK 08-12, TURB LOAD REJECTION C-7A into alarm. Power lowers approximately 10%. Crew may perform a diagnostic brief to identify the cause of the excursion. The crew identifies various indications that the stop valve is fully closed such as deviations in steam flow, temperature, Triconex display, as well as activation of PK04-06, PROTECTION CHANNEL ACTIVATED for 1 out of 4 Turb Stm Stop Vlvs Clsd. Power is stabilized per Shift Foremans direction.
- 5. Loop 4 Feedwater Reg Valve, FCV-540, fails full open. The crew identifies the malfunction and attempts to take manual control, but is unsuccessful. Shift Foreman directs manual reactor trip before S/G 1-4 level reaches the auto trip point of 90%.
- 6. On the trip, the feedline header to S/G 1-4 fails catastrophically, causing S/G 1-4 to depressurize into containment.
- 7. Bus G fails to transfer to startup resulting in a loss of power to the TDAFW LCVs and an inability to throttle flow. Feed flow from the pump is isolated during recovery actions as part of critical task S3CT-1 (see page 4, below).
- 8. Feedwater Isolation Valve FCV-441 fails open, requiring manual isolation at VB-3. (Part of critical task S3CT-1, see page 4, below).

SCENARIO
SUMMARY
- NRC #3 Crew enters EOP E-0, Reactor Trip or Safety Injection and performs their immediate actions. E-0 diagnostic steps direct the crew to E-2, Faulted Steam Generator Isolation to perform the critical task of isolating the feedline break. (S3CT-1) Manually isolate feedline break before Containment wide range level reaches 94 feet, resulting in a magenta path on the Containment safety function status tree. ***
Once isolated, the Shift Foreman verifies SI termination criteria has been met and transitions to E-1.1, SI Termination, performing the critical task of sequentially reducing ECCS flow and realigning the plant to a pre-SI configuration. (S3CT-2) Terminate ECCS flow before overfill of the RCS results in a rupture of the pressurizer relief tank (PRT). ***
The scenario is terminated once normal charging/letdown is aligned in E-1.1, ready to perform step 15.

SCENARIO
SUMMARY
- NRC #4
- 1. AR PK17-06, DIESEL 12 LUBE OIL SYSTEM alarms due to low lube oil temperature on D/G 1-2. When dispatched, the Turbine Watch confirms the input on a local annunciator alarm panel and reports current lube oil temperature = 91oF. Annunciator guidance and Maintenance recommendations are followed to start the diesel to increase lube oil temperature, but the diesel fails to start (over crank condition) bringing in AR PK17-01, DEISEL 12 FAIL TO START. Shift Foreman enters TS 3.8.1.B, AC Sources - Operating, for one D/G inoperable.
- 2. Regen Hx Isolation Valve, LCV-459, drifts to mid-position causing letdown orifice valve 8149C to close.
Shift Foreman enters OP AP-18, Letdown Line Failure. Excess Letdown is established per OP B-1A:IV CVCS - Excess Letdown - Place In Service and Remove From Service.
- 3. SSPS failure results in Turbine Driven AFW (TDAFW) Pump Steam Supply Isolation Valve, FCV-95, failing open causing the TDAFW Pump to start. S/G levels rise and RCS temperature lowers, causing control rods to step out in response. FCV-95 cannot be closed and the crew must isolate the TDAFW Pump by either closing the LCVs to the individual S/Gs or by closing steam supply valves FCV-37 and FCV-38 to leads 1 and 2 respectively. Shift Foreman implements TS 3.7.5.B, AFW System for one AFW train inoperable.
- 4. Crew responds to AR PK14-21, MAIN TRANSF. A nuclear operator is dispatched to investigate local alarms and reports back that NO cooling fans or oil pumps are running on Main Bank C Transformer.
Shift Foreman enters OP AP-25, Rapid Load Reduction or Shutdown and directs a 50 MW/min power reduction while Maintenance and field Operators attempt to restore transformer cooling.
- 5. At approximately 60% power, the plant experiences a Main Transformer Unit Trip due to a fault in the main transformer. D/G 1-1 (no reset) and 1-3 (resettable from Control Room) fail as a result of their associated shutdown relays activating, however all buses successfully transfer to Start-up power. The Turbine trips as expected, but the reactor trip breakers remain closed. (AR PK14-01, UNIT TRIP; AR PK12-11 TURBINE TRIP, AR PK04-11 REACTOR TRIP INITIATE)
- 6. Reactor power is still greater than 50% and the crew identifies the ATWS condition. EOP FR-S.1, Response to Nuclear Power Generation / ATWS, is entered, either directly or from the step 1, response not obtained column of EOP E-0, Reactor Trip or Safety Injection. Attempts to trip the reactor from the Control Room are unsuccessful and Auto-rod motion has failed. The crew performs the critical task of adding negative reactivity by manually driving rods (S4CT-1) Insert negative reactivity into the core so that power is less than 5%.*** The crew continues working through FR-S.1 until field operators are able to locally open the reactor trip breakers.
- 7. The reactor is verified subcritical and the crew transitions to EOP E-0, Reactor Trip or Safety Injection.
EOP E-0.1 Reactor Trip Response is entered once the need for a Safety Injection has been ruled out.
Shortly after verifying primary and secondary parameters are stable, Startup Feeder Breaker 52VU12 trips open and cannot be closed. The crew transitions to EOP ECA-0.0, Loss of All Vital AC Power and performs the critical task of starting D/G 1-3 (S4CT-4) Energize at least one vital AC bus and restore RCP seal cooling before RCP shut down seals activate.***
The scenario is terminated once RCP seal cooling has been re-established.

Description:
12kV Start-Up Feeder Breaker Trip Time Position Applicants Actions or Behavior Note: The Loss of ALL AC develops when the 12kV Start-Up Feeder Breaker trips open. Bus G is de-energized due to event 1 rendering D/G 1-2 inoperable. Shutdown relays activated on D/G 1-1 (no reset) and 1-3 (resettable from the Control Room) during the transfer to Startup earlier in the scenario. Bus F and both diesels failed to start.
ALL Diagnosis of the Loss of AC is made using one or more of the following:
- Many alarms occur, mostly associated with equipment power problems
- All of the vital and non-vital bus white power available lights are out (VB4 and VB5, lower panel, near each mimic bus)
SRO/ATC * (1) Re-verifies reactor trip (trip bkrs open (VB2 upper left), rods on bottom (VB2 upper left DRPI panel), NIs decreasing (CC1 left).
- (2) Re-verifies turbine trip (stop valves closed) (CC3 HMI or VB2 RPS indicator lamps)
