Level RO SRO Tier # 1 Group # 1 K/A # 000007 (CE/E02)EK2.2 Importance Rating 3.5 K/A Statement EK2.2: Knowledge of the interrelations between the (Reactor Trip Recovery) and the following: Facilitys heat removal systems, including primary coolant, emergency coolant, the decay heat removal systems, and relations between the proper operation of these systems to the operation of the facility.

Proposed Question: RO 1 Rev: 0 Given:

Plant is at 100% power SG ILR 1111, Steam Generator 1 Downcomer Level, fails high Crew has entered OP-901-201, Steam Generator Level Control Malfunction Upon a reactor trip, Main Feed Pump A speed will reduce automatically. This design feature was added to reduce the differential pressure across the ____(1)____ valves.

Upon subsequent entry into OP-902-001, Reactor Trip Recovery procedure, the Main Feed Pump A speed controller (FW IHIC1107) will be controlled in the _____(2)_____

mode.

(1) (2)

A. Main Feed Regulating automatic B. Main Feed Isolation automatic C. Main Feed Regulating manual D. Main Feed Isolation manual Revision 0 Facility: Waterford 3 Page 1 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: D Explanation: (Optional)

A. Incorrect: The main feed regulating valve is plausible because it also receives a close signal on MSIS and a reactor trip override (RTO), but is not the reason the design feature was added. Main Feed Pump A speed controller will swap to auto upon the reactor trip for 5 seconds. Because there is a level deviation in this instance the controller will swap back to manual.

B. Incorrect. Part 1 is correct. Main Feed Pump A speed controller will swap to auto upon the reactor trip for 5 seconds. Because there is a level deviation in this instance the controller will swap back to manual.

C. Incorrect. The main feed regulating valve is plausible because it also receives a close signal on MSIS and a reactor trip override, but is not the reason the design feature was added. Part 2 is correct.

D. CORRECT: On a reactor trip override (RTO), FWCS will swap the Main Feed Pump speed controllers to auto and drive them to minimum speed if the controller was in manual. If the controller was in manual due to a level deviation, which in this case it is, the controller will still swap to auto but will return to manual after 5 seconds. As stated in the basis for TS 3.7.6.1, this design feature is to ensure rapid closure of a MFIV on a MSIS by ensuring DP across the valve is reduced.

Level RO SRO Tier # 1 Group # 1 K/A # 000008 AA2.15 Importance Rating 3.9 K/A Statement AA2.15: Ability to determine and interpret the following as they apply to the Pressurizer Vapor Space Accident: ESF control board, valve controls, and indicators.

Proposed Question: RO 2 Rev: 0 The plant was at 100% power when Pressurizer Safety Valve, RC-317A, failed open.

The crew tripped the reactor and initiated SIAS and CIAS.

The following conditions exist:

RCS pressure is 1340 psia and stable Reactor Coolant Pumps have been secured CET is 556°F, Thot is 550°F, Tcold is 543°F (all stable)

Pressurizer level is 70% and rising Quench Tank pressure is 20 psig QSPDS indicates reactor head level 1 voided Steam Generator (SG) 1 and 2 pressures are 980 psia and stable SG 1 and 2 levels are 60% WR and slowly lowering The expected temperature indication of the Pressurizer Relief Line is ____(1)____ °F.

The crew ______(2)______ throttle close Train B High Pressure Safety Injection flow control valves.

(1) (2)

A. 258 will not B. 228 will not C. 258 will D. 228 will Revision 0 Facility: Waterford 3 Page 3 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: A Explanation: (Optional)

A. CORRECT: Quench tank pressure is 20 psig. This pressure must be changed to absolute pressure to determine relief line temperature. The saturation temperature for 35 psia is 258°F. The crew should not close HPSI flow control valves because subcooled margin based on CET is less than 28F The applicant will determine that a leak exists in the pressurizer steam space. Pressurizer level will rise in this event due to RCS voiding and HPSI flow should not be throttled based solely on pressurizer level.

B. Incorrect. Quench tank pressure is 20 psig. This pressure must be changed to absolute pressure to determine relief line temperature. The saturation temperature for 35 psia is 258°F. The distractor is the saturation temperature for 20 psia. Second part is correct.

C. Incorrect. First part is correct. Second part is plausible because pressurizer level is rising rapidly and water solid operations should be avoided unless minimum subcooling (28F) cannot be maintained.

D. Incorrect: Quench tank pressure is 20 psig. This pressure must be changed to absolute pressure to determine relief line temperature. The saturation temperature for 35 psia is 258°F. The distractor is the saturation temperature for 20 psia. Second part is plausible because pressurizer level is rising rapidly and water solid operations should be avoided unless minimum subcooling (28F) cannot be maintained.

Proposed Question: RO 3 Rev: 0 Given:

Small Break LOCA has occurred and the crew has diagnosed to OP-902-002, LOCA Recovery Procedure Pressurizer pressure is 1690 PSIA and slowly lowering Containment pressure is 17.4 psia and slowly rising Containment temperature is 210°F Which of the following ESFAS signal(s) will have been generated?

A. MSIS only B. SIAS and CIAS only C. SIAS, CIAS, and MSIS only D. SIAS, CIAS, MSIS, and CSAS Revision 0 Facility: Waterford 3 Page 5 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect. MSIS is present due to containment pressure above 17.1 PSIA. SIAS and CIAS occur at 1684 PSIA or 17.1 PSIA in containment. Applicant must be aware that PZR pressure is above SIAS and CIAS setpoint but SIAS and CIAS are still in due to containment pressure.

B. Incorrect. SIAS and CIAS occur at 1684 PSIA or 17.1 PSIA in containment. MSIS is also present due to containment pressure above 17.1 PSIA.

C. CORRECT: SIAS, CIAS, and MSIS all actuate at a containment pressure of 17.1 PSIA. A harsh environment exists in containment, the applicant must determine that the containment pressure instruments are not affected by containment temperature above 200°F. Many instruments in containment are affected by the harsh environment, but the pressurizer pressure nor containment pressure instruments that initiate ESFAS signals are affected. The applicant may determine that the instruments are affected and determine the wrong ESFAS initiations. Waterford does not use containment humidity in any of its procedures.

D. Incorrect. CSAS does not occur until 17.7 PSIA.

B. Spent Fuel Pool temperature will lower since CC-134 A, CCW A Dry Cooling Tower Bypass failed open.

C. Spent Fuel Pool temperature will rise since CC-135 A, CCW A Dry Cooling Tower Isolation, failed closed.

D. Spent Fuel Pool temperature is controlled in automatic since the Train B CC-620 control switch is in CONTROL.

Revision 0 Facility: Waterford 3 Page 15 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: A Explanation: (Optional)

A. CORRECT: CC-620 Fuel Pool HX Temperature control valve goes closed on low CCW surge tank level on either side. CC-620 has closed since CC-200A has closed due to the level switch failure. CC-620 is interlocked with C-200A. This will cause Spent fuel pool temperature to rise due to no CCW flow to the Spent Fuel Pool HX.

B. Incorrect: CC-134 A does open if this level switch fails, but ACCW Pump A will auto start and control CCW Train A temperature. SFP temperature rises because of CC-620 closing. The applicant may assume that there is greater flow to the SFP HX since the bypass around the heat exchanger has opened.

C. Incorrect. CC-135 A does close if this level switch fails, but ACCW Pump A will auto start and control CCW Train A temperature. SFP temperature rises because valve CC-620 closes.

D. Incorrect. Even with the Train B control Switch for CC-620 in Control, CC-620 will still close due to the failure of the Train A level switch. CC-620 has an A and B solenoid valve in series.

A. natural circulation conditions are 1101 being met B. at least one RCP is running 907 C. at least one RCP is running 1101 D. natural circulation conditions are 907 being met Revision 0 Facility: Waterford 3 Page 21 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect: At least one RCP operating is required before cooling and depressurizing the isolated SG using the feed and bleed method. Natural circulation conditions are verified in this ORP, but is not a prerequisite for feeding and bleeding a SG. The note before step 50 indicates that RCS boron concentration will lower by 0.6% for each 1% drop in steam generator NR level.

B. Incorrect. Step 50 of OP-902-007 directs the crew to verify at least one RCP operating before cooling and depressurizing the isolated SG using the feed and bleed method. If the crew were to use a 1% drop in RCS boron concentration for each 0.6% drop in steam generator level they would come up with this wrong answer.

C. CORRECT: Step 50 of OP-902-007 directs the crew to verify at least one RCP operating before cooling and depressurizing the isolated SG using the feed and bleed method. The note before step 50 indicates that RCS boron concentration will lower by 0.6% for each 1% drop in steam generator NR level.

D. Incorrect. Step 50 of OP-902-007 directs the crew to verify at least one RCP operating before cooling and depressurizing the isolated SG using the feed and bleed method. If the crew were to use a 1% drop in RCS boron concentration for each 0.6% drop in steam generator level they would come up with this wrong answer.

A. RCS Pressure Control B. RCS Heat Removal C. Containment Isolation D. Containment Temperature and Pressure Control Revision 0 Facility: Waterford 3 Page 23 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: D Explanation: (Optional)

A. Incorrect. RCS pressure Control can be met by LPSI and HPSI pumps providing flow > OP-902-009 Appendix 2 curves. This is implied by the last bullet in the conditions given.

B. Incorrect. RCS Heat Removal. Although S/G 2 level is lowering the final bullet implies that that EFAS-2 actuated per design and EFW is operating per design. The level given would not be low enough yet for EFW to feed S/G 2. Operators are trained to evaluate this safety function as SAT if EFW is automatic and working as designed. Tc can also be implied to be lowering during the blowdown phase of an excess steam demand. The conditions given imply that information.

C. Incorrect. CVC-101, Letdown Stop Valve, is not a containment isolation valve. This valve gets an automatic closure signal on a high Regen HX outlet temperature and is located just upstream of the CVC inside containment isolation valve, CVC-103.

D. CORRECT: At least one Containment Spray pump must be providing > 1750 gpm of flow to meet the CT&PC safety function.

Proposed Question: RO 17 Rev: 0 Given:

Power is 100%

A level switch malfunction has caused the B Dry Cooling Tower to isolate and bypass.

The Control Room has entered OP-901-510, Component Cooling Water (CCW) System Malfunction A Loss of Coolant Accident occurs. Plant conditions are:

Pressurizer pressure is 1600 psia and slowly lowering Containment pressure is 17.3 psia and stable CCW heat exchanger B outlet temperature is 105 ºF If ACCW basin temperature is 80 ºF, ACC-126B, ACC Hdr B CCW HX Outlet Temp Control valve, will be ____(1)____ . This occurs to ______(2)______.

(1) (2)

A. open conserve ultimate heat sink water supply B. closed conserve ultimate heat sink water supply C. open ensure proper component cooling in the Wet mode D. closed ensure proper component cooling in the Wet mode Revision 0 Facility: Waterford 3 Page 33 of 150

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: B Explanation: (Optional)

A. Incorrect: ACC-126B will go closed (ACCW flow will stop) because its setpoint is automatically increased to 115 ºF on SIAS when ACCW basin temperature is >74 ºF.

Normally, a setpoint of 95 ºF would cause the valve to open. Second part is correct.

B. CORRECT: The loss of the Dry Cooling Tower (DCT) will cause CCW temp to rise steadily. SIAS and an ACCW basin temperature of >74 ºF will automatically increase ACC-126B's setpoint from a nominal 95ºF to 115ºF. Another function of ACC-126B is for the valve to remain closed unless the ACCW basin temperature is above 74 ºF this is to ensure proper cooling of Essential Chillers in Wet mode. Even though this interlock is met, ACC-126B will not open until the new setpoint of 115ºF is reached.

TS 3.7.4 bases state that ACCW basin temperature and level limitations are based on a 30-day cooling water supply.

C. Incorrect: First part: Plausible because initially, the loss of the DCT will cause ACC-126B to throttle open and maintain 95 ºF CCW temperature. On SIAS ACCW flow will stop due to a setpoint increase on ACC-126B. Second part: Plausible because a CCW temperature of 102 ºF will cause the Essential Chillers to swap from CCW to ACCW cooling (Wet Mode) to ensure proper cooling, but this is not the reason why ACC-126B closes.

D. Incorrect: First part is correct. Second part is plausible because ACC-126B does not need to be open for ACCW to supply cooling water to the Essential Chiller.

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect: First part is correct. OP-901-201, SG Level Control Malfunction, directs tripping the FWPT with a speed controller malfunction (in this case 3900 rpm indicates a speed controller malfunction). This will initiate a reactor cutback and allow the remaining FWPT to restore SG levels. However, in this case the low SG level RPS setpoint has been exceeded and the reactor must be manually tripped.

B. Incorrect: The pre-trip alarms should be prioritized because these alarms signify SG level is close to a reactor trip setpoint. OP-901-201, SG Level Control Malfunction, directs tripping the FWPT with a speed controller malfunction. This will initiate a reactor cutback and allow the remaining FWPT to restore SG levels. However, in this case the low SG level RPS setpoint has been exceeded and the reactor must be manually tripped.

C. CORRECT: The pre-trip alarms should be prioritized because these alarms signify SG level is close to a reactor trip setpoint. SG level of 26% NR means the reactor should have automatically tripped (ATWS). The correct action is to manually trip the reactor.

D. Incorrect: FWPT low flow alarm is an important alarm and it may prompt action to trip the reactor, however, unlike the SG Lo level pre-trip alarms, it is not a direct indication of approaching an RPS trip setpoint. Second part is correct.

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: D Explanation: (Optional)

A. Incorrect: First part is plausible because an undervoltage on the BT will only open the 3A-to-2A BT breaker but an overcurrent condition will open both BT breakers.

Second part is plausible because given that TCB 9 is removed; a loss on MG A (upon the loss of 3A safety bus) appears to affect CEDMCS power and cause a reactor trip, but it does not. MG B will continue to supply power to all CEAs.

B. Incorrect: First part is plausible because an undervoltage on the BT will only open the 3A-to-2A BT breaker but an overcurrent condition will open both BT breakers.

Second part is correct.

C. Incorrect: First part is correct. Second part is plausible because given that TCB 9 is removed; a loss on MG A (upon the loss of 3A safety bus) appears to affect CEDMCS power and cause a reactor trip, but it does not. MG B will continue to supply power to all CEAs.

D. CORRECT: An overcurrent condition will open both BT breakers. Loss of one safety bus will not directly cause a reactor trip. OP-901-310 provides adequate guidance to mitigate this event.

A. CORRECT: OP-903-066, Electrical Breaker Alignment Check, allows for both Offsite electrical trains to be supplied by the same 230KV bus (i.e. East or West) and still maintain electrical separation and operability. EDG B would be the only inoperable power source. TS 3.8.1.1.b requires restoration within 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months .

B. Incorrect. Plausible because west trains are normally associated with safety train A and TS 3.8.1.1.c requires restoration of either power source within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

C. Incorrect. Plausible because the applicant may determine that train separation does not exist and therefore both offsite electrical circuits are inoperable. TS 3.8.1.1.d has an action to restore an inoperable EDG within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months . This action is preceded by "with one EDG inoperable, in addition to Action b or c above". The applicant may determine that action d covers inoperability in addition to action c.

D. Incorrect. Plausible because the applicant may determine that train separation does not exist and therefore both offsite electrical circuits are inoperable. The applicant may determine that TS 3.8.1.1 does not address one EDG and both offsite circuits being inoperable simultaneously and therefore TS 3.0.3 would apply.

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect. Part 1 is correct. Matching SGFP A's output is plausible since this would match both pump discharge pressures, but as soon as, SGFP B controller is placed in auto the pump would drive itself to its own auto input signal.

B. Incorrect. The speed governor control switch is initially used to manually raise SGFP speed to 3900 rpm. Once the local controls are placed in auto, speed control is transferred to the speed controller (the control switch no longer has any effect on speed). Matching SGFP A's output is plausible since this would match both pump discharge pressures, but as soon as, SGFP B controller is placed in auto the pump would drive itself to its own auto input signal.

C. CORRECT: Once the local speed controls are placed in auto, speed control is transferred to the speed controller (Manual/Auto station) and the controller is used to manually adjust speed. A note prior to step 6.3.24 of OP-003-033 provides three methods that can be used to minimize feedwater flow perturbations. Matching speed controller output to its own input is one of those methods.

D. Incorrect. Once the local speed controls are placed in auto, speed control is transferred to the speed controller and the controller is used to manually adjust speed. Part 2 is correct.

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: A Explanation: (Optional)

A. CORRECT: RCS inventory control safety function requires the RCS to be > 28°F subcooled. The tech guide for standard post trip actions states that this verification for subcooling is to validate pressurizer level indication as being representative of total RCS inventory. (no voiding in the head). This question is TIER 3 because the inventory control SFSC and immediate action is required for any transient involving a reactor trip. This question is comprehensive since the applicant is required to know the reason for subcooled margin requirement in RCS inventory control, which can only be found in the Tech guide.

B. Incorrect. 30°F is plausible since this is the setpoint of the subcooled margin Lo annunciator on CP-8. Part 2 is correct.

C. Incorrect. Part 1 is correct. The crews will use the RCP operating curves to determine if RCPs are required to be secured. Although, the subcooled margin Lo annunciators are used to clue them that the RCP operating curves have been exceeded.

2015 NRC Exam RO Written Exam Worksheet Proposed Answer: A Explanation: (Optional)

A. CORRECT: The BOP must check the main turbine tripped by verifying both governor valves and throttle valves are closed. OI-038-000, EOP Operations Expectations/Guidance procedure, states that the sub steps listed for stopping steam admission to main turbine are listed in a preferred order. If one of the contingency actions results in tripping the main turbine, it is not necessary or desired to perform the remaining contingency steps. Tripping the main turbine using the turbine trip and think pushbuttons is listed before the contingency step for closing both MSIVs. This question is TIER 3 because this step is performed before any optimal recovery procedure entry and the guidance to answer the second portion correctly is contained in the EOP Operations Expectations/Guidance procedure.

B. Incorrect. Verifying only the governor valves are closed does not comply with the minimum requirements of OP-902-000 to check the main turbine is tripped. The sub steps listed for stopping steam admission to the main turbine are listed in a preferred order as stated in OI-038-000. An attempt must be made to trip the main turbine first by using the trip pushbuttons.

C. Incorrect. Part 1 is correct. The sub steps listed for stopping steam admission to the main turbine are listed in a preferred order as stated in OI-038-000. An attempt must be made to trip the main turbine first by using the trip pushbuttons before closing both MSIVs..

A. Incorrect. Part 1 is correct. A steam generator tube rupture event is plausible since it is an event that the RCS will lose inventory and both the ADV and HPSI is procedurally operated.

B. Incorrect. Determining that the automatic actuation channel is operable is plausible since the operator could restore the ADV auto function simply by placing the controller back to auto. In this instance, nothing is wrong with the auto actuation inputs. A steam generator tube rupture event is plausible since it is an event that the RCS will lose inventory and both the ADV and HPSI is procedurally operated.

C. CORRECT: The basis for TS 3.7.1.7 states that At greater than 70% rated thermal power, one high pressure safety injection train and one ADV, in automatic, are capable of mitigating the SBLOCA event. The basis also states that the action for automatic control of an ADV must be entered if the automatic controls for auto actuation are placed in manual.

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect. This step is performed to eliminate boron precipitation in the vessel, the applicant could determine that SI flows are the initiating parameters since they would be affected by boron precipitation. Two hours from the event is plausible because two hours is the minimum time required to align hot and cold leg injection. The two hour requirement ensures that borated water injected to the hot leg is not entrained in the steam being released through the break.

B. Incorrect. Part 1 is correct. Two hours from the event is plausible because two hours is the minimum time required to align hot and cold leg injection. The two hour requirement ensures that borated water injected to the hot leg is not entrained in the steam being released through the break.

C. CORRECT: Step 50 of OP-902-002 requires the crew to evaluate the need for hot and cold leg injection based on Pressurizer level, Reactor vessel level and RCS subcooling. OP-902-002 Tech guide states that hot and cold injection must be performed within three hours of the event to prevent boric acid precipitation in the core.

D. Incorrect. Step 50 of OP-902-002 requires the crew to evaluate the need for hot and cold leg injection based on Pressurizer level, Reactor vessel level and RCS subcooling. Since this step is performed to eliminate boron precipitation in the vessel, the applicant could determine that SI flows are the initiating parameters. Part 2 is correct.

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: D Explanation: (Optional)

A. Incorrect. Transitioning to OP-901-212 (Rapid Down Power) is plausible because leakage has increased. If primary to secondary leakage is small and pressurizer level can be maintained the crew is expected to remain in OP-901-202. However, in this case, leakage is in excess of Charging pump capacity and EOP entry is warranted. Part 2 is plausible because the step to de-pressurize the RCS lists several criteria; <930 psia is one of those criteria and the reason to minimize leakage is correct. However, TGOP-902-007 pg. 29 says that the requirement to maintain RCP NPSH takes precedence over the strategy to equalize primary and secondary pressures.

B. Incorrect. Part 1 is correct. Maintaining RCP NPSH takes precedence over the strategy to equalize primary and secondary pressures (TGOP-902-007 pg. 29).

C. Incorrect. Leakage is in excess of Charging pump capacity and EOP entry is warranted. Part 2 is correct.

D. CORRECT: A leak rate of 95 gpm is in excess of Charging pump capacity. EOP entry would be warranted and OP-902-007 would be diagnosed. Both OP-902-007 and OP-901-202 have similar steps to cooldown and de-pressurize the RCS. No indication is given that the plant is on natural circulation therefore RCP operation must be assumed and depressurizing to 1150 psia would maintain RCP NPSH requirements. Maintaining RCP NPSH takes precedence over the strategy to equalize primary and secondary pressures (TGOP-902-007 pg. 29).

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: B Explanation: (Optional)

A. Incorrect. Plausible because this is the desired response if all CCW is lost to the RCPs. The applicant could determine that CC-200A and 727 are closed and there is not enough time to gag open CC-200A and CC-727 within 3 minutes. Part 2 is correct.

B. CORRECT: Per step 18 of OP-901-511, Loss of instrument Air: If the loss of instrument air is expected to last longer than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months , then actions must be taken within 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months . The applicant will determine that since the flow lost annunciator is clear to the RCPs that are running, CCW flow must still exist. By procedure, the CRS will direct gagging open CC-200A and CC-727 before they fail closed.

C. Incorrect. Part 1 is correct. OP-901-510 deals with CCW malfunctions but does not provide guidance for a loss of instrument air and nitrogen accumulators to CCW valves.

D. Incorrect. Plausible because this is the desired response if all CCW is lost to the RCPs. The applicant could determine that CC-200A and CC-727 are closed and there is not enough time to gag them open within 3 minutes. The guidance to trip the Reactor Coolant Pumps on a loss of CCW is located in OP-901-510 but is the wrong response.

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect: The CP-2 digital meter is fed by the same input as the PMC (pulse counter). In this case (slipped rod) the pulse counter will not see the change in rod position since the rod had no motion demand and it did not drop to the bottom of the core. Part 2 is correct.

B. Incorrect: Part 1 is correct. PMC indication although erroneous would be expected to read 150 inches and therefore not an indication malfunction.

C. CORRECT: CPC indication is fed from safety grade RSPT indication which provides actual rod position. All indications reported by the ATC with the exception of the PMC indication are consistent with a rod misalignment.

D. Incorrect: The CP-2 digital meter is fed by the same input as the PMC (pulse counter). In this case (slipped rod) the pulse counter will not see the change in rod position since the rod had no motion demand and it did not drop to the bottom of the core.

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: B Explanation: (Optional)

A. Incorrect. 14 HG Vacuum requires taking action to protect the main condenser by isolating steam inputs to the condenser. This is done after the reactor is tripped which should occur when approaching 20 Hg Vacuum. Correct procedure implementation strategy.

B. CORRECT: The Main Turbine trip setpoint for lo vacuum is 20 Hg Vacuum. OP-901-220 requires tripping the reactor at this point to prevent intentionally putting the primary through a loss of load transient which would result in potentially quick opening all 6 Steam Bypass Valves and directing high energy steam into the condenser when vacuum is already challenged. In most cases, the offnormal procedures are exited or suspended while performing OP-902-000. OP-901-220 specifically states to implement the procedure concurrently with OP-902-000.

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: C Explanation: (Optional)

A. Incorrect. OP-901-210 provides no guidance for responding to a hydrogen gas leak in the main generator. The first step in the Excessive Generator Hydrogen Gas Leakage section of the offnormal will direct the crew to make a plant page to secure hot work or open flames in the TGB. The reason for this action is indicated in the Warning prior to step 1.

B. Incorrect. OP-901-210 provides no guidance for responding to a hydrogen gas leak in the main generator. The offnormal is plausible since the main turbine was manually tripped. Part 2 is correct.

C. CORRECT: (W3 OE, CR-WF3-2008-1165) OP-901-211 provides the guidance for responding to lowering hydrogen pressure in the Main Generator. The crew is required to trip the turbine at 34 psig in the Main Generator.

Level RO SRO Tier # 3 Group # 4 K/A # 2.4.35 Importance Rating 4.0 K/A Statement 2.4.35 Knowledge of local auxiliary operator tasks during an emergency and the resultant operational effects.

Proposed Question: SRO 25 Rev: 0 Given:

A reactor trip has occurred

The crew is performing Standard Post Trip actions per OP-902-000 and power to the Moisture Separator Re-heater (MSR) Control panel is not available.

The BOP will direct the auxiliary operator to isolate the Moisture Separator Re-heaters by ____(1)____ valves. This action is required to _____(2)_____ .

(1) (2)

A. manually closing temperature control prevent overcooling the valve isolation RCS B. failing closed air operated prevent overcooling the temperature control RCS C. failing closed air operated prevent over-temperature control pressurization of the MSR D. manually closing temperature control prevent over-valve isolation pressurization of the MSR Revision 0 Facility: Waterford 3 Page 49 of 50

2015 NRC Exam SRO Written Exam Worksheet Proposed Answer: B Explanation: (Optional)

A. Incorrect. OI-038-000, EOP Operations/Expectations procedure directs the crew to isolate the MSR by isolating the air and opening the petcock to all 5 inch and 10 inch valves. MOV isolation valves are located on the same line as the AOVs but are automatically closed by the AOV limit switches. Part 2 is correct.

B. CORRECT: OI-038-000, EOP Operations/Expectations procedure states If power to the MSR control panel is not available, then the Control Room should direct the NAO to isolate the MSR. The NAO should isolate the air and open the petcock to all 5 inch and 10 inch valves. This guidance is not located in EOPs and is applicable during all events. Therefore this question is Tier 3.

C. Incorrect. Part 1 is correct. These actions will eliminate steam to the MSR thereby it is plausible to consider that closing the valves will prevent over-pressurization of the MSR.

D. Incorrect. OI-038-000, EOP Operations/Expectations procedure directs the crew to isolate the MSR by isolating the air and opening the petcock to all 5 inch and 10 inch valves. MOV isolation valves are located on the same line as the AOVs but are automatically closed by the AOV limit switches. This action will eliminate steam to the MSR thereby it is plausible to consider that closing the valves will prevent over-pressurization of the MSR.

ES-401 Record of Rejected K/As Form ES-401-4 Tier / Randomly Reason for Rejection Group Selected K/A 1/1 000022/AA1.07 W3 does not have an excess letdown system. Randomly selected another K/A from the AA1 section of 000022.

Question Randomly selected 000022 AA1.01, CVCS letdown and

6 charging.

1/1 00055/ 2.2.39 W3 does not have one hour TS actions for a Station Blackout. Tech Specs are not addressed when in EOP Question space. Randomly selected a different K/A under

14 Equipment Control (2.2.37) while remaining in the SBO area.

1/2 00036/ 2.4.1 W3 has no EOP entry or immediate action steps for a fuel handling accident. W3 has an offnormal procedure Question for guidance upon a fuel handling accident. Randomly

22 selected a different K/A under the Emergency Procedures section (2.4.11) while remaining in the fuel accident area.

1/2 00059/ AK 1.05 Calculation of offsite doses due to a release from the LWM system is not performed by a LO at W3, therefore, Question no guidance exist in any operations procedures.

23 Randomly selected an Emergency or Plant Evolution from Tier 1/Group 2 limited to those not used in the original outline, then randomly selected a K/A from the AK1 area. Randomly selected 037 Steam Generator tube leakage AK1.01 1/2 CE/A16 AK3.1 A question could not be developed for this K/A that was supported by written guidance. The W3 RCS leak Question offnormal does not go into the level of detail to support

27 this K/A. Randomly selected a different K/A for RCS leakage while staying in the AK3 area. Randomly selected CE/A16 AK3.3.

2/1 003 A1.01 A question could not be developed for this K/A. The RCP off-normal does not have specific guidance that Question would support a test question. The W3 off-normal has

28 guidance to get Engineering input on high vibration and actions to be taken if the SM/CRS determines that the vibration is valid. There is no trigger points nor expected mil values for the RO to take actions based on RCP vibration. Randomly selected a different K/A for the RCP system while staying in the A1 area. Randomly selected 003 A1.09

2/1 062 A2.08 A question could not be developed or modified for this K/A that would deviate enough from questions Question developed from the previous two exams. Randomly

46 selected a different K/A for the AC electrical distribution system while staying in the A2 area. The allotment of 4 questions from the previous two exams has already been used. Randomly selected 062 A2.09 2/1 064 A2.16 A question could not be developed for this K/A that was supported by written guidance. W3 has a procedure for Question full load testing of the EDG but no guidance in the

49 surveillance procedure to take if a loss of offsite power occurred during this testing. Randomly selected a different K/A for the EDG system while staying in the A2 area. Randomly selected 064 A2.09.

2/1 076 K4.06 The W3 Auxiliary Component Cooling Water (ACCW)

Question system does not have an interlock or design feature that

53 will separate trains. The W3 component cooling water system will separate trains and isolate safety and non safety systems. We refer to our ACCW system as the Service Water system as represented in the K/A catalog.

Randomly selected a different K/A for the Service Water system while staying in the K4 area. Randomly selected 076 K4.02 2/2 041 K4.11 The W3 SDS system does not input to nor receive an Question input from the Tave/Tref program. Randomly select a

61 system from Tier 2/ Group 2 not previously used.

Randomly selected a new K4 K/A from this system.

Randomly selected 016 K4.03.

2/2 068/ K 5.04 Could not develop a question for Biological hazards of radiation and the resulting goal of ALARA for LWM Question release without selecting a theory question. Operations

63 procedures also have no written guidance for this subject. Randomly selected a K/A from Tier 2/Group 2 system not previously used while remaining in the K5 area. Randomly selected 001 K5.08

2/2 071 K3.04 W3 does not have written guidance on a loss or Question malfunction of the waste gas disposal system having an

64 affect on ventilation systems. The Gaseous Waste Management (GWM) system will isolate on high radiation but will not affect a ventilation system. Due to this, we were unable to develop a question that met the K/A. Randomly selected a different K/A for the Waste Gas Disposal system while staying in the K3 area.

Randomly selected 071 K3.05 3/4 2.4.22 W3 does not have written guidance on the bases for prioritizing safety functions during emergency Question operations. Could not develop a question with an

73 adequate LOD without having the RO prioritize safety functions in our functional recovery procedure (SRO knowledge). Randomly selected a K/A from section 2.4 ensuring not to use a 2.4 K/A already selected on this outline. Randomly selected 2.4.12 Knowledge of general operating crew responsibilities during emergency operations
