Note:

1.

Ensure that at least two topics from every applicable K/A category are sampled within each tier of the RO and SRO-only outlines (i.e., except for one category in Tier 3 of the SRO-only outline, the Tier Totals in each K/A category shall not be less than two). (One Tier 3 Radiation Control K/A is allowed if the K/A is replaced by a K/A from another Tier 3 Category).

2.

The point total for each group and tier in the proposed outline must match that specified in the table. The final point total for each group and tier may deviate by +/-1 from that specified in the table based on NRC revisions. The final RO exam must total 75 points and the SRO-only exam must total 25 points.

3.

Systems/evolutions within each group are identified on the associated outline; systems or evolutions that do not apply at the facility should be deleted with justification; operationally important, site-specific systems/evolutions that are not included on the outline should be added. Refer to Section D.1.b of ES-401 for guidance regarding the elimination of inappropriate K/A statements.

4.

Select topics from as many systems and evolutions as possible; sample every system or evolution in the group before selecting a second topic for any system or evolution.

5.

Absent a plant-specific priority, only those K/As having an importance rating (IR) of 2.5 or higher shall be selected. Use the RO and SRO ratings for the RO and SRO-only portions, respectively.

6.

Select SRO topics for Tiers 1 and 2 from the shaded systems and K/A categories.

7.

The generic (G) K/As in Tiers 1 and 2 shall be selected from Section 2 of the K/A Catalog, but the topics must be relevant to the applicable evolution or system. Refer to Section D.1.b of ES-401 for the applicable K/As.

8.

On the following pages, enter the K/A numbers, a brief description of each topic, the topics importance ratings (IRs) for the applicable license level, and the point totals (#) for each system and category. Enter the group and tier totals for each category in the table above; if fuel handling equipment is sampled in a category other than Category A2 or G* on the SRO-only exam, enter it on the left side of Column A2 for Tier 2, Group 2 (Note #1 does not apply). Use duplicate pages for RO and SRO-only exams.

9.

For Tier 3, select topics from Section 2 of the K/A catalog, and enter the K/A numbers, descriptions, IRs, and point totals (#) on Form ES-401-3. Limit SRO selections to K/As that are linked to 10 CFR 55.43.

Note:

1.

Ensure that at least two topics from every applicable K/A category are sampled within each tier of the RO and SRO-only outlines (i.e., except for one category in Tier 3 of the SRO-only outline, the Tier Totals in each K/A category shall not be less than two). (One Tier 3 Radiation Control K/A is allowed if the K/A is replaced by a K/A from another Tier 3 Category).

2.

The point total for each group and tier in the proposed outline must match that specified in the table. The final point total for each group and tier may deviate by +/-1 from that specified in the table based on NRC revisions. The final RO exam must total 75 points and the SRO-only exam must total 25 points.

3.

Systems/evolutions within each group are identified on the associated outline; systems or evolutions that do not apply at the facility should be deleted with justification; operationally important, site-specific systems/evolutions that are not included on the outline should be added. Refer to Section D.1.b of ES-401 for guidance regarding the elimination of inappropriate K/A statements.

4.

Select topics from as many systems and evolutions as possible; sample every system or evolution in the group before selecting a second topic for any system or evolution.

5.

Absent a plant-specific priority, only those K/As having an importance rating (IR) of 2.5 or higher shall be selected. Use the RO and SRO ratings for the RO and SRO-only portions, respectively.

6.

Select SRO topics for Tiers 1 and 2 from the shaded systems and K/A categories.

7.

The generic (G) K/As in Tiers 1 and 2 shall be selected from Section 2 of the K/A Catalog, but the topics must be relevant to the applicable evolution or system. Refer to Section D.1.b of ES-401 for the applicable K/As.

8.

On the following pages, enter the K/A numbers, a brief description of each topic, the topics importance ratings (IRs) for the applicable license level, and the point totals (#) for each system and category. Enter the group and tier totals for each category in the table above; if fuel handling equipment is sampled in a category other than Category A2 or G* on the SRO-only exam, enter it on the left side of Column A2 for Tier 2, Group 2 (Note #1 does not apply). Use duplicate pages for RO and SRO-only exams.

9.

For Tier 3, select topics from Section 2 of the K/A catalog, and enter the K/A numbers, descriptions, IRs, and point totals (#) on Form ES-401-3. Limit SRO selections to K/As that are linked to 10 CFR 55.43.

SUMMARY

- NRC #1

1.

Control rods are used to raise power from 2% to 8% OP L-3, Secondary Plant Startup, step 6.28. ATC operator complies with 1 step pull and wait procedural requirement while monitoring relevant controls and diverse indicators. Shift Foreman provides reactivity oversight.

2.

S/G Blowdown RM-23 fails high resulting in only a partial blowdown isolation. The crew responds, manually isolating the unactuated sample isolation valves and realigning blowdown discharge to the Equipment Drain Receiver, following the guidance of AR PK11-17, SG BLOW DOWN HI RAD. Shift Foreman enters ECG 39.3.B, Radioactive Liquid Effluent Monitoring Instrumentation, for Steam Generator Blowdown Tank (RM-23) inoperable.

3.

Charging Pump CCP 1-2 trips on over current. The crew responds by entering OP AP-17, Loss of Charging to restore normal charging and letdown. Shift Foreman enters Tech Spec 3.5.2.A, ECCS - Operating, for one ECCS train inoperable.

4.

PT-507, Steam Generator Header Pressure Transmitter, slowly fails low causing Group I dumps to close.

Crew diagnoses the failure 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 to normal bands.

5.

MFP 1-1 trips on high vibration. Both MDAFW pumps start initially, but trip on overcurrent. The crew enters AR PK09-12, Main Feedwater Pump Trip, and follow the guidance of OP AP-15, Loss of Feedwater Flow, Section B: Single Operating MFP Trips, starting the TDAFW pump, tripping the turbine, and inserting rods in manual to reduce power to 2%. Shift Foreman enters Tech Spec 3.7.5.D, AFW System, for two AFW trains inoperable.

6.

S/G 1-1 Safety lifts causing uncontrollable depressurization of S/G 1-1. Shift Foreman directs board operators to trip the reactor and initiate Safety Injection once reactor trip has been verified. The crew enters EOP E-0, Reactor Trip or Safety Injection. The safety valve reseats 45 seconds after Safety Injection initiates. The crew throttles AFW to control the cooldown as they work their way towards SI termination.

7.

CCP 1-1 fails due to a sheared shaft 30 seconds after SI actuation. The board operator identifies the condition based on low motor amps and flow.

8.

Board operators also identify PCV-455C in mid-position. The valve will not close and must be isolated using the associated block valve 8000B (S1CT-1) Close the block MOV upstream of the stuck open PORV before performing step 8 of EOP E-0).

9.

Once termination criteria has been met, the crew transitions to EOP E-1.1, SI Termination. A SBLOCA occurs immediately following the shutdown of Safety Injection Pump 1-2. The crew performs the final critical task of reinitiating Safety Injection (S1CT-2) Reinitate SI before a severe challenge to the Core Cooling Critical Safety Function develops (magenta path on F-0.2 Core Cooling).

The scenario is terminated once ECCS pumps have been restarted.

SUMMARY

- NRC #2

1.

Generator Voltage Regulator trips due to a loss of sensing voltage. The crew responds by entering AR PK14-22, GENERATOR VLTG REG TRIP and determine the voltage regulator is now operating in manual mode. Annunciator guidance is followed to maintain a lagging power factor.

2.

Letdown Hx Inlet Valve, CVCS-8152 fails 90% closed causing letdown to divert to the Pressurizer Relief Tank. AR PK04-21, LETDOWN PRESS / FLOW TEMP comes into alarm, directing the crew to isolate Normal Letdown and place Excess Letdown in service per OP B-1A:IV, CVCS - Excess Letdown - Place In Service and Remove From Service. Alternately, the crew may elect to enter OP AP-18, Letdown Line Failure, which provides equivalent guidance. Shift Foreman enters TS 3.6.3.A - Containment Isolation Valves, for one containment isolation valve inoperable.

3.

A 0.12 g seismic event results in a rupture of RWST, causing level to lower rapidly. The crew identifies RWST level lowering by monitoring level indications on VB-2 or by evaluating AR PK06-20, PPC Select which identifies RWST level is below the alarm setpoint. Field operators report a crack in the RWST extending down to approximately the 50% level. The Shift Foreman enters TS 3.5.4.B - Refueling Water Storage Tank (RWST) for borated water volume less than the required minimum of 455,300 gallons

(~94%).

4.

Vibrations on MFP 1-2 rise to 2.5 mil which corresponds to a ODM limit, requiring predesignated Unit 1 shutdown at 6 MW/min. A ramp is commenced following the guidance of OP AP-25, Rapid Load Reduction or Shutdown.

5.

A 0.20 g seismic aftershock results in 100% DBA LOCA.

6.

The crew enters E-0, Reactor Trip or Safety Injection, performing their immediate actions. A reactor trip fails to automatically actuate (ATWS); manual Rx Trip control switches are ineffective as well. Control board operators perform their respective response actions: ATC drives control rods inward and BOP manually opens control rod breakers 13D/E on VB5 (S2CT-1) Initiate reactor trip prior to performance of E-0, step 2).

7.

With the reactor tripped, the crew continues on, checking for actuation of emergency safeguards equipment and diagnosing conditions consistent with a large break LOCA (high containment pressure, loss of pressurizer pressure and level, loss of subcooling, high containment sump levels). The crew identifies RCP trip criteria are met, and with Shift Foreman concurrence, trip all four RCPs. Shift Foreman directs the BOP Operator to complete Appendix E, ESF AUTO ACTIONS, SECONDARY AND AUXILIARIES STATUS, and continues on in E-0. Train A of Phase A, Containment Isolation, fails to actuate, requiring board operators to manually align the associated inside containment isolation valves.

SUMMARY

8.

The Shift Foreman continues through E-0 diagnostic steps, and transitions to E-1, Loss of Reactor or Secondary Coolant. Functional restoration status trees are checked and crew identifies transition criteria for FR-P.1, Response to Imminent Pressurized Thermal Shock. Conditions will be met for exiting the procedure at the first step.

When RWST level reaches 33%, the crew transitions immediately to E-1.3, Transfer to Cold Leg Recirculation, and performs the required alignment steps. When RWST suction valve SI-8980 is isolated, ECCS recirculation flow is lost due to sump blockage. The crew transitions to ECA-1.3, Sump Blockage either directly, or by way of ECA-1.1, Loss of Emergency Coolant Recirculation, where they secure all running ECCS pumps (S2CT-2, Stop all running ECCS pumps with suction aligned to the containment recirc sump by the completion of ECA-1.3, step 5).

The scenario is terminated once Critical Task S2CT-2 is complete.

SUMMARY

- NRC #3

1.

Startup Transformer 1-1 Load Tap Changer control power supply fails. Crew responds per AR PK20-04, SU TRANSF 11, 12, OR 21 LOCAL ANNUN, and manually controls transformer voltage. Shift Foreman enters TS 3.8.1.A, AC Sources - Operating for one required offsite circuit inoperable.

2.

Letdown heat exchanger temperature element TE-130 fails high, causing actual letdown temperature to lower. AR PK04-21, LETDOWN PRESS / FLO TEMP comes into alarm, directing the crew to take manual control of letdown temperature (TCV-130), to restore temperature to normal range. Alternately, the crew may elect to follow the guidance of OP AP-5, Malfunction of Eagle 21 Protection or Control Channel.

3.

Shift Manager reports a confirmed Grid Control Center backdown order due to grid instability. Unit 1 is directed to shed 150 MW within 15 minutes. The Shift Foreman determines an appropriate ramp rate to meet the backdown order requirement (may assign this task to reactor operator) and implements OP AP-25, Rapid Load Reduction or Shutdown. The ATC determines an initial boration based on the Reactivity Handbook and advises the Shift Foreman of his recommendation. The BOP enters the programmed ramp into the turbine control system. The reactivity evolutions are implemented sequentially, with the Shift Foreman providing oversight.

4.

DRPI power failure due to normal supply breaker tripping open near the end of the ramp. Ramp is placed on hold, rods are taken to manual, and Tave is matched within 1.5 oF (if required) per AR PK03-21, DRPI FAILURE / ROD BOTTOM. The Shift Foreman enters TS 3.1.7.B - Rod Position Indication for more than one DRPI per group inoperable.

5.

A main steamline break develops downstream of the Main Steam Isolation Valves, outside containment.

The crew identifies the need to isolate the Main Steam Isolation Valves and perform a safety injection (SI) based on pressurizer pressure and level lowering rapidly. Shift Foreman directs a reactor trip and SI and enters EOP E-0, Reactor Trip or Safety Injection.

6.

All four main steam isolation valves fail open. The crew transitions to EOP E-2, Faulted Steam Generator Isolation, and then to EOP ECA-2.1, Uncontrolled Depressurization of All Steam Generators. The crew performs the critical tasks of stopping the uncontrolled cooldown (S3CT-1) Stop uncontrolled cooldown before a severe challenge (magenta path ) develops on F-0.4 RCS Integrity by minimizing feedflow and then terminating safety injection (S3CT-2) Terminate SI prior to rupture of PRT.

Steam Generator Level below 15% narrow range in 1 of 4 loops after a power level dependent time delay, normally generates a reactor trip signal to protect against a loss of heat sink. For this scenario, power remains above 50%, so the time delay = 0.

Once the S/G has reached dry out conditions, it is no longer capable of RCS heat removal.

Furthermore, the S/G is susceptible to structural damage as the result of thermal shock once feedwater is re-established from the Auxiliary Feedwater System.

SUMMARY

- NRC #4

1.

Power Range Nuclear Instrument NI-41 slowly fails high causing inward rod motion. Crew diagnoses failure, and once motion is deemed unwarranted, takes rods to manual. Failure is addressed per OP AP-5, Malfunction of Eagle 21 Protection or Control Channel, which removes the failed channel from service and directs the Shift Foreman to address Tech Specs 3.3.1.D,E,S,T Reactor Trip System Instrumentation; ECG 37.2 Axial Flux Difference (AFD) monitoring, and ECG 37.3 (Quadrant Power Tilt Ratio Alarms).

2.

PT-403, RCS Wide Range Pressure Transmitter, fails low. The crew responds to PK05-07, Subcooling Margin Lo/Lo-Lo and PK05-09, RVLIS Lo Lvl RVLIS/SCMM Trouble, identifying the affected instrumentation. Shift Foreman addresses TS 3.3.3.A, Post Accident Monitoring Instrumentation

3.

A saltwater leak develops in the SW quadrant of the condenser, bringing in AR PK12-05, COND PPS DISCH HDR CATION CONDT'Y HI. The crew determines cation conductivity is elevated and the Shift Foreman enters OP AP-20, Condenser Tube Leak, which calls for a 25 MW/min ramp to 50%. The crew immediately implements OP AP-25, Rapid Load Reduction or Shutdown to commence the ramp.

4.

Annunciator AR PK10-06, CNDS & CNDS BSTR PPS comes into alarm due to rising bearing temperatures on Condensate Booster Pump Set (CBP) 1-3. Reactor operators identify rapidly rising bearing temperatures using plant process computer trends. The crew manually starts CBP 1-2 and secures CBP 1-3 to prevent motor damage.

(Note: Malfunction is designed to trip CBP 1-3 if crew has not shut the pump down within 15 seconds of bearing temperature reaching 280oF. The Autostart of CBP 1-2 has been disabled and will require a manual start).

5.

A 0.15 seismic event results in Main Feed Reg valve FCV-510 failing closed. S/G 1-1 level can not be maintained. S/G 1-1 Low Level trip has been disabled and the crew must manually trip the reactor (S4CT-1) Manually trip the reactor before S/G 1-1 reaches dry out conditions.

6.

A 600 gpm tube rupture develops on S/G 1-2 when the reactor trips. The crew enters EOP E-0, Reactor Trip or Safety Injection, and identifies the rupture based on various radiation alarms, rising counts on RM-72, and the inability to maintain RCS pressure and pressurizer level following the trip.

7.

Both auto and manual Safety Injection (SI) actuation signals fail and the crew must manually start and align SI actuated equipment (S4CT-2) Manually align at least one train of SIS actuated safeguards before transition out of EOP E-0.

(continued on next page)

SUMMARY

- NRC #4

8.

The crew transitions to EOP E-3, Steam Generator Tube Rupture, and where they perform the critical task of isolating S/G 1-2 (S4CT-3) Isolate the ruptured steam generator from the intact steam generators prior to commencing cooldown of the RCS.*** Depressurization of the RCS is commenced following the cooldown. Pressurizer spray valves fail to operate and a PORV must be used. When the crew attempts to stop the depressurization, both the PORV and associated block valve fail to operate in the closed direction, and the Shift Foreman transitions to EOP ECA-3.1, SGTR with Loss of Reactor Coolant - Subcooled Recovery Desired.

The scenario is terminated once the cooldown to Cold Shutdown in ECA-3.1 has been commenced or verified.

CT / TCOA note: SGTR was evaluated against Time Critical Operator Actions (TCOAs) # 2 (SGTR); initial power level and supporting equipment conditions differ significantly from the conditions used in this scenario. For these reasons, the S/G TCOAs will remain critical (a critical task, per WOG), but TCOA time limits will not be applied to this scenario.

RCPs are susceptible to catastrophic failure and a loss of reactor coolant flow if left running in the absence of adequate bearing cooling flow. If the reactor is at power at the time of the accident, the immediate effect of loss of coolant flow is a rapid increase in the coolant temperature. This increase could result in DNB with subsequent fuel damage if the reactor is not tripped promptly.

• FSAR Accident Analysis, Section 15.2.5 - Partial Loss of Forced Ractor Coolant Flow (S5CT-2) Establish a secondary heat sink as indicated by:

WR level rising Core Exit Thermocouple temperatures lowering Prior to reaching bleed and feed criteria which is defined as wide range S/G level in any three S/Gs less than 18% [26%] AND narrow range S/G level in all four S/Gs less than 15% [25%] narrow range.

A loss of all feedwater transient is characterized by a depletion of secondary inventory and eventual degradation of secondary heat transfer capability.

As secondary heat transfer capability degrades, core decay heat generation will increase RCS temperature and pressure causing loss of RCS inventory similar in nature to a small break loss of coolant accident. Failure to restore a secondary heat sink when it is possible to do so constitutes a significant reduction of safety margin beyond that irreparably introduced by the scenario.

SUMMARY

- NRC #5

1.

Pressurizer Pressure Control Valve PCV-474 drifts open and must be isolated using the associated 8000-A block valve. Shift Forman enters TS 3.4.11.B Pressurizer Power Operated Relief Valves (PORVs) - for one PORV inoperable for reasons other than excessive seat leakage.

2.

Running ASW Pump 1-1 experiences a ground on 4 kV Bus F. The crew follows the guidance of AR PK18-23, 4KV BUS F GROUND OC ALARM, and shuts down ASW pump 1-1 after starting the 1-2 pump. Shift Forman enters TS 3.7.8.A, Auxiliary Saltwater (ASW) System for one train inoperable.

3.

Low Stator Coil Cooling Water flow causes a turbine runback. The crew responds per AR PK14-19, STATOR WTR CLG SYSTEM, and OP AP-25, Rapid Load Reduction or Shutdown. The low flow condition clears quickly (approximately 925 MW), and the crew stabilizes the plant.

4.

In-service Seal Injection Filter 1-1 plugs, reducing flow to RCP seals and bringing in AR PK04-22, RCP Seal Inj Fltr Delta-P Hi. Reactor Operators verify CCP seal cooling is still being maintained by CCW and ATC operator throttles RCP seal injection hand control valve, HCV-142, as needed to maintain pressurizer level. Shift Foreman establishes bands for pressurizer level and confirms field operators have been dispatched to swap seal injection filters.

5.

A spurious actuation of Train A, Phase B results in the isolation of CCW Header C. The crew responds per AR PK01-08, CCW HEADER C, or alternately, OP AP-11, Section E: Loss of CCW Flow to RCPs, which calls for tripping the reactor and then tripping all four RCPs. (S5CT-1) Trip all four Reactor Coolant Pumps (RCPs).

6.

The crew enters E-0, Reactor Trip or Safety Injection and performs their immediate actions. On the trip, 4 kV bus F trips on differential. DRPI loses power, but crew is able to determine the reactor has tripped based on diverse indications (lowering reactor power and reactor trip breakers open). MDAFW Pump 1-3 is also lost due to the bus failure. Both main feedpumps trip and the TDAFW pump trips on overspeed leading to Loss of Heat Sink condition. The crew transitions to EOP FR-H.1, Response to Loss of Secondary Heat Sink. With the condenser available, Main Feed is used to restore a secondary side heat sink (S5CT-2) Establish a secondary heat sink.

The scenario is terminated once Critical Task S5CT-2 is complete.
