ES-301 Administrative Topics Outline Form ES-301-1 Facility: Columbia Date of Examination: February 2013 Examination Level: RO SRO Operating Test Number: 1 Administrative Topic Type Describe activity to be performed (See Note) Code*
Determine if APRM indication is greater than reactor power as calculated from Main Turbine Bypass Valve position and Reactor Feedwater temperature (2.1.25 RO 3.9). Given the positions of the four Main Turbine Bypass Valves, Reactor Feedwater Conduct of Operations M, R temperature and house loads, calculate current reactor power by plotting the values on the Core Thermal Power Versus Bypass Valve Position graph in PPM 3.1.2 and summing the values. Compare the results to the APRM reading to determine if APRM indications are greater than reactor power.
Use procedures to assign operators to the positions required to meet minimum crew compliment (2.1.5 RO 2.9). Provided a list of the On-Coming crew Conduct of Operations N, R operators and the PQD Viewer duty areas, assign operators to positions to meet the requirements for the minimum crew compliment.
Use electrical prints to determine why RHR-P-2C did not start following a manual initiation (2.2.41 RO Equipment Control M, R 3.5). Given a set of initial conditions, explain which contacts prevent starting RHR-P-2C using the ARM
& DEPRESS pushbutton.
Use radiological survey maps to determine the minimum and maximum stay times until radiation Radiation Control D, R, P exposure limits are reached (2.3.4 RO 3.2). Given year-to-date exposure and work instructions, refer to radiological survey maps to determine work area radiation levels and calculate the time at which a
radiation exposure limit will be reached.

ES-301 Administrative Topics Outline Form ES-301-1 Facility: Columbia Date of Examination: February 2013 Examination Level: RO SRO Operating Test Number: 1 Administrative Topic Type Describe activity to be performed (See Note) Code*
Determine if a MODE change is allowed during a plant startup (2.1.23 SRO 4.4). With a plant startup in progress, the SRO candidate is provided a list of Conduct of Operations D, R plant conditions and required to determine if a MODE change is allowed. The candidate must recognize that HPCS is inoperable and LCO 3.0.4 is not applicable.
Use procedures to project On-Coming Crews watch manning, and verify qualifications meet the minimum requirements (2.1.5 SRO 3.9). Provided the list of Conduct of Operations N, R operators scheduled for the new crew starting a series of nightshifts and PQD Viewer areas, the SRO candidate must determine that the minimum qualifications are not satisfied.
Maintain control of equipment status by issuing a Fire Protection System Impairment (2.2.14 SRO 4.3).
During the performance of a surveillance, two Main Equipment Control M, R Control Room Halon Tanks have been reported to have UNSAT pressures. The SRO candidate must determine that a Fire Protection System Impairment is required to track the equipment status, and complete the Impairment.
The SRO Candidate is tasked with reviewing a request to initiate blowdown from the Circulating Water and Plant Service Water systems (2.3.6 SRO Radiation Control D, P, R 3.8). Given parameters associated with CW and TSW blowdown, the SRO candidate must determine that the minimum instrumentation required to initiate blowdown is not available, and should not be
allowed.
The SRO Candidate is given that a UE was previously declared due to a credible threat security Emergency event. The situation then escalates and the SRO has D, R Procedures/Plan to determine that an Emergency Plan upgrade is required, the applicable EAL and then fill out the required Classification Notification Form.

NRC EXAM SCENARIO #1 Initial conditions: The plant is operating at 100% power. TSW-P-1A is tagged out for motor replacement. The reactivity brief and task preview for the shifts scheduled activities have been completed.
Shift Directions: Per the Reactivity Control Plan, reduce reactor power with flow to 90%. Concurrent with the power reduction, perform OSP-MS-M701, Bypass Valves Test.
Event Timeline Event Type* Event Description No.
1 T=0 R (ATC) Power reduction to 90% by lowering RRC flow.
R (CRS) 2 T=0 C (BOP) Perform OSP-MS-M701, Main Turbine Bypass Valves Test. BV3 fails to open, requiring BPVs to be declared inoperable (Tech Spec).
3 T = 20 I (ATC) RFW-LI-606A (the selected NR instrument) fails downscale (Tech Spec).
I (CRS) 4 T = 35 I (BOP) Fire in the Turbine Building resulting in degrading Control Air header pressure. Both standby CAS compressors fail to auto start on low header pressure, and must be manually started to restore header pressure.
5 T = 45 M (All) Loss of CAS-C-1A and CAS-C-1B.
A manual rector scram is required prior to MSIV closure.
6 T = 55 M (All) A Steam LOCA develops inside containment when the MSIVs close.
7 T = 60 C (BOP) When Drywell pressure reaches 1.68 psig, RHR-P-2A will automatically start with an overcurrent condition. The output breaker will fail to trip and cause C (CRS) a lockout on SM-7. DG-1 must be emergency tripped.
8 T = 65 C (BOP) RHR-P-2B fails to auto start. RHR-P-2B has a sheared shaft when manually started. Initiate Drywell sprays with SW-B through RHR-B using PPM 5.5.2 C (CRS) after Drywell temperature reaches 285°F, but before Drywell temperature reaches 330°F (Critical Task).
Secure Drywell sprays when Drywell pressure drops to LT 12 psig and before it drops to -0.5 psig (Critical Task).

Appendix D NRC EXAM SCENARIO #1 FORM ES-D-1 The scenario starts with Columbia at 100% power. TSW-P-1A is tagged out for motor replacement.
After the crew takes the shift, power is to be lowered to 90% for economic dispatch request from BPA. The crew will lower power with RRC flow.
At the same time, the BOP operator will perform BPV surveillance test, OSP-MS-M701. When the third bypass valve is tested, it will not open. The CRS will refer to Tech Specs and enter TS 3.7.6.
After Tech Specs are referenced, RFW-LI-606A will fail downscale. The crew will swap FWLC channels from Channel A to Channel B. Tech Spec again will be referenced.
The next event is a fire in the Aux Boiler Room, Turbine Building 441 elevation East side. The fire will cause a rupture in the Control Air System. CAS pressure will slowly drop. ABN-FIRE and ABN-CAS will be entered. The Standby CAS compressors will not auto start but may be started manually. When started, CAS pressure will start to recover.
Due to a failed fire hose that occurs during firefighting efforts, CAS-C-1A and CAS-C-1B become wetted and will trip.
With only one CAS compressor running, CAS pressure will again begin to drop. Firefighting efforts will put the fire out.
When it is determined that a complete loss of air is apparent, the crew will insert a manual scram (should be prior to MSIVs going closed which would cause an automatic scram).
When the MSIVs close, a Steam LOCA inside containment will occur causing a High Drywell Pressure signal at 1.68 psig.
When RHR-P-2A starts on high Drywell pressure, it will have an overcurrent fault. The breaker on SM-7 will not open, and a lockout on SM-7 will occur. The crew will emergency trip DG-1 which will be running with no Service Water.
Additionally, RHR-P-2B will not auto start on high Drywell pressure but may be manually started. When it is started the shaft will shear and the pump will develop no discharge pressure.
The crew will realize that both RRC pumps are running without RCC flow (RRC pumps tripped off on the high drywell pressure signal). When the stop pushbutton for RRC-P-1A is depressed it will not stop the pump. The crew will open one of the supply breakers to stop RRC-P-1A.
Wetwell pressure will rise to 2 psig and the crew will want to spray the Wetwell but will realize both RHR spray systems are not operational.
Drywell/Wetwell pressure and Drywell temperature will continue to rise. The crew will perform PPM 5.5.2, RHR/SW Crosstie Lineup.
Wetwell sprays will be initiated (GT 2 psig Wetwell pressure). Drywell Sprays will be initiated when Drywell temperature reaches 285°F or Wetwell pressure reaches 12 psig. (Note: After MSIVs close it takes 5 minutes and 15 seconds to get to 285°F DW/T, 6 minutes and 15 seconds to get to 12 psig WW/P, and 12 minutes to get to 330°F DW/T) (Critical Task).
LO001750 Rev. 0 Page 3 of 29
Appendix D NRC EXAM SCENARIO #1 FORM ES-D-1 Drywell Sprays will be secured when Drywell Pressure drops to LT 12 psig and before Drywell Pressure drops to LT -
0.5 psig (Critical Task).
The scenario will be terminated when drywell sprays have been secured.

Appendix D NRC EXAM SCENARIO #2 FORM ES-D-1 The scenario starts with Columbia at approximately 75% power. HPCS-P-1 is OOS due to shaft replacement.
After shift turnover reactor power will be lowered with core flow to 70% to support a control rod set.
During the control rod set, one of the previously moved control rods will begin to drift out of the core. The ATC operator will recognize this and take actions to insert the control rod, which will insert. When the insert pushbutton is released, the control rod will again begin to drift out of the core. The ATC operator will again insert the control rod and the crew will take action to isolate that rod. Tech Spec will be referenced.
After Tech Specs have been referenced a SGT-B high temperature alarm will occur due to a strip heater failing to de-energize. The BOP operator will respond and start SGT-B per and then start SGT-A which will cause temperature to drop. Tech Specs will be referenced.
The next event is a failure of IBD-FN-1A. The BOP operator will respond to annunciators and report the failure of IBD-FN-1A and refer to ARPs. He will note that IBD-FN-1B should have auto started but did not and start IBD-FN-1B.
The next event is an Operating Basis Earthquake which results in a trip of one of the two operating Reactor Feedwater Pumps, RFW-P-1A. During verification of automatic actions the ATC operator will find that the automatic runback of the Reactor Recirculation Pumps did not occur. Manual actions to lower RRC pumps to 30 Hz will be successful.
After the plant stabilizes, the Turbine Building watch will contact the Control Room and inform them that the reason RFW-P-1A tripped was a rupture of the control oil system and that there is a leak in the control oil system on RFW-P-1B. Ten seconds later RFW-P-1B will trip. The crew should attempt to insert a manual scram prior to the automatic scram at +13 inches.
When the Main Turbine trips and the electrical plant transfers to the Startup Transformer, the startup breakers associated with SM-1, SM-2 and SM-3 will not auto close. This results in a loss of all operating Condensate Pumps, closure of the MSIVs, a loss of CRD and a trip of the Control Air Systems Air Compressors. The crew will take action to establish RPV level control with the RCIC system, and restart CRD pumps (HPCS-P-1 is OOS at the beginning of the scenario). Pressure control will be on SRVs at 800 - 1000 psig.
An aftershock will result in a rupture of the RHR-A suction line from the suppression pool causing flooding in the A-RHR room. The crew will take action per EOP PPM 5.3.1 (Secondary Containment Control). During verification of automatic actions the crew will recognize that the cross connect valve between RHR-A room and the RCIC pump room, FDR-V-607, failed to automatically close (due to a failed R1 sump level switch). Prior to reaching Maximum Safe Operating Value in the RCIC pump room, the crew will manually close FDR-V-607 with the control switch which is located on back panel H13-P632.
Makeup to the Suppression Pool cannot be performed due to HPCS being OOS.
The crew should initiate an Emergency Depressurization per PPM 5.1.3, RPV Depressurization, before Suppression Pool water level drops to 19 feet 2 inches.
The scenario will be terminated when an Emergency Depressurization has been performed and RPV level is being returned to +13 to +54 level band.

NOTE: It takes about five minutes after trigger actuation to get the RHR-A Pump Room High Level EOP entry alarm and BISI. The R1 sump high level alarm does not annunciate due to failed level switch which also causes FDR-V-607 not to auto close.
BOP Acknowledges RHR A PUMP ROOM WATER LEVEL HIGH annunciator and BISI and reports EOP entry into PPM 5.3.1 (Secondary Containment Control).
Refers to ARP:
May contact the RWCR Operator to verify sump pumps FDR-P-1A and FDR-P-1B operating.
Refers CRS to ABN-FLOODING.

Appendix D NRC EXAM SCENARIO #3 FORM ES-D-1 Columbia is at 95% power due to economic dispatch. BPA has just requested Columbia return to 100%. Additionally, OSP-HPCS/IST-Q701 is in progress and will be continued after shift turnover.
The ATC will raise reactor power with RRC flow to achieve 100% power.
The BOP operator will perform the HPCS surveillance. As full flow test conditions are established, the Min Flow valve for HPCS-P-1 fuses will clear. The crew should back out of the surveillance and secure HPCS-P-1. Tech Specs will be referenced and HPCS will be declared inoperable.
The next event is a trip of CRD-P-1B on low suction pressure. ABN-CRD will be entered and both suction filters will be placed into service. CRD-P-1A will be started.
The next event is a grid disturbance that results in multiple annunciators and ASD Channel 1B1 tripping causing RRC-P-1B to run back to 51 Hz. The crew will lower RRC-P-1A speed to match loop flows.
Another grid disturbance will result in a lockout on SH-5 and then SH-6 which results in a loss of both RRC pumps. Per immediate actions of ABN-RRC-LOSS a manual reactor scram will be inserted.
The crew will recognize a hydraulic ATWS condition exists. The crew will take manual control of HPCS and will inhibit ADS. RCIC-V-1 will be closed to prevent RCIC initiation at -50 (which would cause the Main Turbine to trip).
Standby Liquid Control will be initiated and when initiated, SLC flow will be only 18 gpm due to relief valves lifting.
PPM 5.5.6 will be performed to prevent the MSIVs from closing when RPV level is lowered.
PPM 5.5.1 will be performed to make all ECCS injection valves throttleable.
The crew will stop and prevent injection into the RPV and establish an Lowered Level of -65 with RPV level being maintained between -80 and -140.
PPM 5.5.11 will be performed to insert control rods.
Control rods will go in after RPV level has been lowered and is being controlled -80 to -140.
When all control rods are inserted the crew will stop SLC injection and return RPV level back to +13 to +54 level band.
The scenario will be terminated when RPV level has been returned to normal.
