Appendix D NUREG 1021 Revision 9
2013 NRC Scenario 1 Scenario Outline Form ES-D-1 The following notation is used in the ES-D-2 form Time column:
IOA designates Immediate Operator Action steps
- designates Continuous Action steps The crew will assume the watch having been pre-briefed on the Initial Conditions, the plan for this shift and any related operating procedures.
EVENT 1: Lower Power to Conduct Turbine Valve Testing The crew will lower power from 100% to less than 90% in accordance with GOP-4B, Power Operation MODE 1 - Descending.
EVENT 2: B SG Level Transmitter Fails HIGH On cue from the Examiner, B SG level transmitter will fail HIGH, requiring manual control of the B SG Feedwater Regulating Valve to maintain/restore SG level to between 60% and 65% and prevent a reactor trip.
The crew will enter AOP-401.11, Steam Generator Level Control and Protection Channel Failure, and remove the channel from service.
The CRS will refer to Tech Specs 3.3-1, Item 13 (Action 6) and 3.3-3, Items 5, 6c (Action 24) to determine that the protection bistables for the failed channels must be placed in the TRIPPED condition with 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
EVENT 3: Turbine 1st Stage Pressure Transmitter Fails LOW On cue from the Examiner, PT-446 (Selected turbine first stage pressure transmitter) will fail LOW. The failure causes a Tave - Tref mismatch resulting in rods inserting at the maximum speed.
The crew will enter AOP-401.7, Turbine First Stage Pressure Channel Failure.
The RO will place rod control in manual and maintain Tave within 1 degree of Tref. The RO will then select the operable 1st stage pressure channel for control. The RO may restore automatic rod control after the operable channel is selected.
The BOP will control B Steam Generator NR level and change the Steam Dump Mode to Steam Pressure.
EVENT 4: Running EHC pump trips on overload (Backup pump does not start in auto)
On cue from the Examiner, the running EHC pump will trip and the backup pump will not start in auto.
The BOP will recognize the condition from annunciator XCP-631 1-4, EHC PP A Motor Ovrld, or determine the cause of the event, and take corrective action by starting the backup EHC pump to prevent turbine stop valves from closing.
Appendix D NUREG 1021 Revision 9
2013 NRC Scenario 1 Scenario Outline Form ES-D-1 EVENT 5: A SGTL On cue from the Examiner, a steam generator tube leak will begin. The tube leak on the SG A will initiate and stabilize at 12 GPM. The crew will respond to indications of RCS inventory loss/rising secondary-side radiation and enter AOP-112.2, Steam Generator Tube Leak Not Requiring SI. The crew will estimate SGTL as greater than the TS limit and the CRS will enter TS 3.4.6.2.c. The RO will stabilize PZR level by increasing charging and minimizing letdown. The CRS will direct a shutdown to HOT STANDBY in accordance with the requirements of AOP-112.2 since the shutdown rate specified by that procedure is greater than that specified by the TS.
EVENT 6: A SGTR On cue from the Examiner, a steam generator tube rupture will occur. The crew will recognize the increase in tube leakage greater than the capacity of the charging pumps. The crew will trip the reactor/turbine and implement EOP-1.0 (E-0), Reactor Trip/Safety Injection Actuation. The crew will transition to EOP-4.0 (E-3), Steam Generator Tube Rupture. In EOP-4.0 (E-3), isolate the A SG and cool down and depressurize the RCS to terminate break flow.
EVENT 7: B SG Pressure Transmitter PT-2010 Fails HI Event 7 is triggered automatically after the reactor trip. The BOP may identify the PT-2010 indicates 1300 psig and/or the B SG Power Operated Relief Valve (PORV) indicates open. The operator will place the controller to manual and close the PORV.
If the failure is not identified the crew may transition to EOP 3.0 (E-2), Faulted Steam Generator Isolation, to isolate the SG.
CRITICAL TASKS:
It is a critical task to Isolate B SG PORV prior to B SG Pressure less than 460 psig.
It is critical to terminate Safety Injection prior to the A steam generator reaching the level of the steamline to preclude failure of the steam line. This level, including tolerances, is 87% NR in the EOP network.
It is a critical task to stop RCPs if RCS pressure is < 1418 psig and before WR 33% RVLIS.
TERMINATION:
The scenario can be terminated after the crew has closed the SG PORV and Safety Injection has been terminated.

IOA designates Immediate Operator Action steps
- designates Continuous Action steps The crew will assume the watch having been pre-briefed on the Initial Conditions, the plan for this shift and any related operating procedures.
The turbine startup has been stabilized at 39% and GOP-4A, Power Operation (Mode 1 - Ascending) has been completed to Step 3.12.k.
EVENT 1: Increase Power Power has been stabilized at 40% power and a second Main Feedwater Pump has been placed in service by the off-going crew. The turnover directs the crew to increase power to 48% in accordance with GOP-4A continuing at step 3.13b. (0.5%/minute)
EVENT 2: PRNIS Channel N-44 Fails HIGH On cue from the Examiner, PRNIS Channel N-44 fails High. The RO will respond to alarms and uncontrolled rod motion by performing the immediate actions of AOP-401.10, Power Range Channel Failure; placing rod control in MANUAL. The crew should restore Tave if necessary. The BOP will remove the channel from service and the CRS will enter Technical Specification 3.3.1.
EVENT 3: Emergency Feedwater Pump Suction Pressure Transmitter PT-3635 Fails LOW On cue from the Examiner PT-3635 fails Low. The RO will respond to the alarm. The CRS will diagnose the problem as the failure of PT-3635. He will refer to Tech Specs and determine the failed channel must be placed in Bypass and restored to service within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
EVENT 4: Feedwater Pump Master Speed Controller Fails LOW On cue from the Examiner, the Feedwater Pump Master Speed Controller will fail low causing main feed pump speed to decrease. The BOP will respond to alarms and lowering SG level by controlling FWP Speed IAW AOP-210.3, Feedwater Pump Malfunction and/or Main Control Board Annunciators, SG A(B)(C) STF>FWF Mismatch (XCP-624 4-3(5-3)(6-3)) or SG A (B) (C) LVL DEV XCP-624 1-5(2-5)(3-5).
EVENT 5: RCP A Vibration On cue from the Examiner, RCP A vibration will begin. The crew will respond to alarms/indication and enter XCP-617 1-3. The Crew will trip the reactor and stop the RCP based on shaft vibration greater than or equal to 20 mils or greater than or equal to 15 mils and increasing at greater than one mil per hour. The Crew will then implement EOP-1.0.
Appendix D NUREG 1021 Revision 9
2013 NRC Scenario 2 Scenario Outline Form ES-D-1 EVENT 6: Small-Break LOCA After EOP-1.0 (E-0) the crew will enter EOP 1.1 (ES-0.1), Reactor Trip Recovery. A LOCA will be initiated from the RCP seal package. When SI actuates automatically or manually (PZR level cant be maintained > 8% or loss of adequate subcooling) the crew will transition back to EOP-1.0 (E-0).
After the Safety Injection Actuation MVG- 8801A and MVG-8801B will fail to open causing a complete loss of the high head injection function. The A SW Booster Pumps will also fail to start. The crew will perform the alternative actions of manually opening MVG- 8801 A and B and manually starting the A Service Water Booster Pump.
The crew will implement EOP-2.0 (E-1), Loss of Reactor or Secondary Coolant. When RCS pressure is less than 1418 psig and SI flow is indicated on FI-943, CHG LOOP B CLD/HOT LG FLOW GPM then ALL running RCPs will be stopped.
CRITICAL TASKS:
It is critical that the two remaining RCPs be secured after RCS pressure lowers to less than 1418 psig and high head injection is established to lower the rate of inventory loss. They must be tripped before WR RVLIS level indicates 33% (50% void fraction for 2 RCPs). At this level significant core uncover would occur upon tripping the RCPs.
It is critical that high head Safety Injection be established by opening MVG-8801 (A or B) prior to NR RVLIS < 34% or CETs > 725°F.
TERMINATION:
The scenario will terminate when EOP-2.0 (E-1) is complete and the crew transitions to EOP-2.1 (ES-1.2), Post-LOCA Cooldown and Depressurization or at the discretion of the Examiner.

IOA designates Immediate Operator Action steps
- designates Continuous Action steps The crew will assume the watch having been pre-briefed on the Initial Conditions, the plan for this shift and any related operating procedures.
The scenario involves a plant startup so GOP-3, Reactor Startup from Hot Standby to Startup (Mode 3 to Mode 2), is being implemented. Step 3.13 has been completed and the reactor is critical in Mode 2. The secondary plant has been warmed with the turbine on turning gear.
The scenario starts on step 3.14. Power will be raised to the Point of Adding Heat.
EVENT 1: Normal Power Increase The RO will increase Reactor Power to the Point of Adding Heat and the crew will transition to GOP-4A, Power Operation (Mode 1 - Ascending). GTP-702 Attachment II G, Operational Mode Change Plant Startup - Entering Mode 1, is complete.
EVENT 2: A MDEFW Pump Trip On cue from the Examiner at approximately 1-3% power the A MDEFW will trip.
In accordance with XCP-622 1-3, MD EFP A Trip EFW flow must be reduced to below 400 gpm. The EFW flow requirement is approximately 180 gpm/percent so power is limited to approximately 2% using the B MDEFW unless the crew decides to use the TDEFW Pump.
The BOP will throttle EFW flow to the S/Gs using the B MDEFW IAW SOP-211, Emergency Feedwater System.
The CRS will evaluate the failure and determine that the A MSEFW Pump is inoperable and Tech Spec 3.7.1.2 applies. The action statement requires that be returned to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

Bearing temperatures will increase until the pump is stopped or an auto trip occurs. The operators will start the C CWP and verify proper operation.
EVENT 5: Charging Pump Sheared Shaft NOTE: The BOP will be called to the HVAC so the RO will perform the required actions.
The A Charging Pump shaft will shear. The RO will align and start the C Charging pump on the A Header. Permission to start the Charging Pump will be granted by a SS role player in the booth.
EVENT 6: Two Dropped Rods On cue from the Examiner, one rod will drop to the fully inserted position. The RO will take immediate actions IAW AOP-403.6, Dropped Control Rod. A second rod will drop 60 seconds after the first. IAW AOP-403.6, Dropped Control Rod, the RO will trip the Reactor and implement EOP-1.0 (E-0) Reactor Trip/Safety Injection Actuation.
EVENT 7: Steam Space LOCA A steam space LOCA will be automatically triggered on the Reactor Trip. Safety Injection will initiate on Low RCS Pressure. The crew will transition from EOP-1.0 (E-0) to EOP-2.0 (E-1).
EVENT 8: Containment penetration valves XVA9312 A & B fail to close on Phase A This event is the result of the Safety Injection Actuation. The BOP must close at least one Phase A isolation valve in the unisolated line (RMA-2 Sample Isolation Valves) during the conduct of EOP-1.0, Attachment 3 - SI Equipment Verification.
EVENT 9: The running Charging Pump will trip on the SI and will not restart This event is the result of the Safety Injection Actuation. One Charging pump was previously faulted. The running charging pump will trip on the SI and cannot be restarted. The sequence to restore charging flow is dependent on previous actions:
If the B Charging pump was running, the C charging pump must be racked-up and started.
If the C Charging pump was running, the B charging pump can be manually started from the MCB.
The crew will transition to EOP-2.0 (E-1), Loss of Reactor or Secondary Coolant, based on containment conditions. The crew will later transition to EOP-2.1 (ES-1.2), Post-LOCA Cooldown and Depressurization.
