ILO NRC Initial Exam Scenario 1 Narrative Summary Initial conditions establish Reactor Power at 71%, necessary to best facilitate the RR Pump uncontrolled speed increase malfunction >10% (Malfunction 1). The CRS will be directing crew actions per the GOP, which produces a Normal activity for BOP to start a HFP, and a Reactivity maneuver for the RO to increase power (10-15%) with RR flow.
After a short brief the CRS will direct ATC to commence raising power with recirc flow. The ATC will raise power with recirc flow until he reaches the recirc speed oscillation region (49%-54%) for both recirc pumps. ATC will report conditions and obtain permission to split recirc speeds to raise each RR Pump through the speed oscillation region. He will then increase speed on each RR Pump until it is clear of the oscillation region.
When directed, BOP will start the East HFP per the GOPs direction.
After the East HFP is started reactor power will again be raised with recirc flow. When RRMG Set speed is 58%,
the RR speed control malfunction will be automatically initiated. ATC will take immediate action to lock the scoop tube, if not already locked, and trip RRMG B due to a > 10% speed change. The CRS will direct crew response via AOP 20.138.03, Uncontrolled Recirc Flow Change.
This will result in single-loop operation and entry into AOP 20.138.01, Recirc Pump Trip and require CRS to comply with TS LCOs. Depending on where the crew is on the power to flow map, they will probably find themselves in the Exit Region. NOTE: The operating Recirc Pump Speed will be 58% and it will be in the desired single loop speed range of 50 - 75%. With OPRMs operable they should monitor for instability and exit the region as soon as possible. The best way to accomplish this is to raise speed on the operating Recirc Pump until out of the Exit Region.
In response to a Loss of Heater Drains resulting from the transient, the CRS will also direct BOP to evaluate the effects on Feedwater Heating and determine Loss of Feedwater Heating AOP applicability.
A malfunction will result in spurious auto-initiation and injection by RCIC. It is expected that the BOP will trip RCIC under CRS direction. This establishes conditions which will later require manual re-start of RCIC, if selected for level-control post LOCA. CRS will evaluate and comply with TS LCOs, and should coordinate with support personnel to control/protect unaffected ECCS equipment.
An electrical fault on the 345kV distribution system will result in an interruption of Division 2 electrical power, a coincidental loss of feedwater, and Rx Scram (either manual or automatic). The Division 2 EDGs will re-energize the ESF Buses. The crew will enter AOPs 20.300.345kv, Loss of 345 Kv, and 20.000.21, Reactor Scram. After Scram Reports, the CRS will enter EOP 29.100.01, RPV Control, Sheet 1 (Level 3).
The loss of feedwater/scram will challenge RPV Level Control, which will be complicated by the LOCA, a loss of all Heater Feed Pumps and two Condenser Pumps, an auto start failure of HPCI, a loss of power to the Standby Feedwater discharge valve, and the earlier trip of RCIC.
Options available to restore RPV level include manual start of HPCI, re-starting RCIC, or opening the discharge valve and restoring Standby Feedwater (either manually or electrically after resetting overloads). If HPCI is manually started it will isolate after ~1 minute. When the only SBFW Pump (A) is started, the discharge valve will fail to open (N2103-F001). The valve will lose power shortly after receiving the open signal.
The only available high pressure injection sources available will be CRD A Pump, SLC A Pump, and RCIC, when re-started.
A Recirc leak will require the CRS to direct EOP actions to recover RPV level and protect the primary containment from overpressure. EOPs 29.100.01, RPV Control and Primary Containment Control, Sheets 1 & 2 will be entered on high drywell pressure. Most typically the ATC will be tasked with containment sprays, and BOP assigned to restore and maintain level.
When the CRS directs the ATC to, Verify EECW is initiated, isolated from the drywell, and restore cooling to CRD, the ATC will discover the P4400-F606B failed to isolate. He will report and close the valve.
At ~100" RPV Water Level, the BOP will report that RPV Water Level cannot be maintained >TAF. This will prompt the CRS to brief the crew for Emergency Depressurization.
At TAF (0 core level), the crew will Emergency Depressurize (EOP C-2) (CT) in accordance with 29.100.01, RF/ED/SC, Sheet 3. BOP will be directed to open 5 SRVs, ADS preferred. The crew will then brief and develop a plan for water level recovery, while the plant is being monitored during depressurization.
Appendix D, 38 of 39
When LP sources inject and water level is restored >TAF, the crew will coordinate removal of injection systems to maintain RPV Water Level 173 - 214". (CT)
When level is recovered and stabilized, ATC will spray the Torus and Drywell to control Primary Containment Pressure. (CT)
The scenario will be terminated when the plant is stabilized, and evaluation activities are complete.

ILO NRC Initial Exam Scenario 2 Narrative Summary Initial conditions establish Reactor Power at 100%, with a plan to shift the operating divisions of CCHVAC to support maintenance. The crew will have briefed this activity prior to entering the simulator. The CCHVAC shift in accordance with SOP 23.413, Control Center HVAC is a Normal activity for BOP.
A Control Rod Drift (Out of the core), which will raise reactor power to ~ 102%. This event will be identified and responded to by the ATC (ARP 3D80, CONTROL ROD DRIFT). Subsequent actions will be directed by the CRS from AOP 20.106.07, Control Rod Drift after restoring power to 100%. The CRS will review and take actions per TS.
A Seismic Event will occur, and be followed by a subsequent aftershock. The CRS will initially direct BOP response actions per the Acts of Nature AOP 20.000.01, Act of Nature, Earthquake. When the BOP starts the MDCT Fans, per the AOP, MDCT Fan B will trip. The CRS will review and take actions per TS.
A resultant condenser vacuum leak will be identified by lowering Main Condenser vacuum, at which time the CRS will direct actions per AOP 20.125.01, Loss of Condenser Vacuum. The CRS will direct ATC to lower power via Rapid Power Reduction (SOP 23.623, Reactor Manual Control System, Section 9.7). The Manual Runback pushbutton, on P603, malfunctions and ATC must take individual manual control of both Recirc Controllers to accomplish the Recirc Runback. BOP attempts to restore vacuum by operation of various Off-Gas System components and controls under CRS direction.
Continually lowering Main Condenser vacuum is expected to result in a manual scram
( 2.5 psia), prior to a main turbine trip. The Mode Switch will be taken to Shutdown and all rods will insert. After Scram Reports, the CRS will enter EOP 29.100.01, RPV Control, Sheet 1 (Level 3) and AOP 20.000.21, Reactor Scram. The crew controls RPV Water Level 173 - 214.
A second seismic event (aftershock) results in failure of both Div 1 and 2 RPV Level instrumentation reference legs and Floodup Level indication. This causes a loss of all RPV level indication. The BOP will determine that, RPV Level CANNOT be determined. NOTE: Main Turbine, RFPs, HPCI, RCIC, and SBFW will all have Level 8 trips.
The CRS enters (EOP C-4) EOP 29.100.01, RF/ED/SC, Sheet 3 (RPV Flooding). Flooding will be complicated during the depressurization phase when one of the preferred SRVs (R) fails to open. BOP is expected to identify this failure and take action to open an alternate valve.
Appendix D, 38 of 39
The CRS will direct defeat 29.ESP.19 or BOP to depress and hold N2103-F001 pushbutton, to defeat the SBFW L8.
The CRS will direct Low Pressure ECCS Systems to be started in preparation for injection, when reactor pressure decreases to within their injection capability.
The scenario will be terminated after RPV Flooding conditions are established.

The plant has been operating for 403 days. Reactor Power is currently 100% of RTP with Control Rods at the 100% Rod Line following rod pattern adjustment. The N. Turbine Lube Oil Vapor Extractor is out of service for motor replacement. APRM #1 has failed downscale and is bypassed. I&C is working on the APRM failure. The shift is to remove the North TBCCW Pump from service for lubrication and outboard motor bearing replacement. The shift is also to perform 27.109.01, Turbine Steam Valves Test and will lower power to 93%.
NOTE: Pre-job Briefing for the reactor power decrease and Turbine Steam Valves Test is to be conducted prior to entering the simulator. (Suggested time 30 minutes prior to beginning the scenario.)

Initial conditions establish Reactor Power at 100% with the N. Turbine Lube Oil Vapor Extractor out of service for motor replacement. The crew plans to shift the operating TBCCW Pumps to remove the North for scheduled maintenance. The crew will have briefed this activity prior to entering the simulator. The TBCCW shift is in accordance with SOP 23.128, TBCCW System and is a Normal activity for BOP.
Power will be lowered to 93% in accordance with GOP 22.000.03, Power Operation 25% to 100% to 25%, to support the performance of surveillance 27.109.01, Turbine Steam Valves.
APRM #2 Fails High. ATC will evaluate alarms and report the failure. The CRS will evaluate and direct bypassing the APRM. The ATC will bypass the APRM per 23.605, APRM System, Section 6.4. An operator will be directed to the Relay Room to investigate and report all indications. The CRS will evaluate the failure and apply Tech Specs. (Tracking LCO)
SRV G will fail open. BOP will perform immediate actions to close the SRV. He should repeatedly depress the OPEN and then the Close pushbuttons, observing plant response, between cycles of the pushbuttons. The CRS will enter AOP 20.000.25, Failed SRV. After several attempts, the SRV will close. The SRV will fail open a second time, and the BOP and CRS will repeat the previous actions. The CRS should declare the SRV inoperable and take actions per the AOP Enclosure A (remove fuses) to ensure the SRV remains closed. The CRS will review and take actions per TS.
The CRD Flow Control Valve will begin oscillating, resulting in oscillating flow. The ATC will observe and report. The CRS will enter AOP 20.106.03, CRD Flow Control Valve Failure. The crew takes action by placing the valve controller in manual. The valve/flow will stop oscillating, and ATC will manually adjust CRD flow as necessary.
The Main Turbine trips, but RPS fails to actuate resulting in a failure to scram (ATWS). RPV Water Level decreases rapidly to below Level 1, and the MSIVs close. ATC reports Failure to Scram, and the crew enters the EOPs on Scram Condition and Rx power cannot be determined to be <3%. After Scram Reports, the CRS directs actions from 29.100.01 Sheet 1A, RPV Control-ATWS. ATC performs FSQ 1-8 actions (unsuccessful). The success path for the ATWS is manual rod insertion and level-power control.
The BOP inhibits ADS, and if time allows before MSIV closure, he bypasses and restores Drywell Pneumatics. When directed, he controls level 0-50 inches on Core Level (to maintain power low) until SLC is injected and rods are inserted. He maintains pressure 900-1050 psig using Low-Low Set.
When ATC reports FSQ 1-8 is complete, the CRS directs SLC initiation. ATC initiates SLC, but the first pump trips. He starts the other pump, reports the events, and gives his Standard SLC Report, also reports that the first pump tripped. He then attempts to drift rods and then drives rods.
When 29.ESP.10 defeats are installed, ATC resets ARI and drains the SDV per 29.ESP.03, Scram-Reset-Scram, Section 4.0, so the reactor can be re-scrammed. When the SDV is drained (3D94 clear), the reactor is re-scrammed (using ARI), and all rods are fully inserted.
The scenario may be terminated after all rods are in.
