Q1 - NRC recommended changes to Rev 1 Notes:

Rev 1 Notes are acceptable, however format/style below should be considered for future question submittals. Also, spell out RTR the first time used, and correct spelling of the word Reactor or Trip the Rector A. Incorrect. OP-2202.002 directs using AFW pump 2P-75 to feed the SGs. Plausible because EFAS is manually actuated during SPTAs, at Step 8.A (Contingency Actions), because FW will not be maintaining SG levels. However, during implementation of OP-2202.002, operators will secure 2P-7A/B and start 2P-75 to feed the SGs.

B. Incorrect. OP-2202.002 directs using AFW pump 2P-75 to feed the SGs. Plausible because EFAS is manually actuated during SPTAs, at Step 8.A (Contingency Actions), because FW will not be maintaining SG levels. However, during implementation of OP-2202.002, operators will secure 2P-7A/B and start 2P-75 to feed the SGs.

C. Correct. Based on OP-2202.002, Step 12.A (Contingency Actions), the operators are directed to start and commence SG feed with AFW pump 2P-75 using 2202.010, Standard Attachments, Attachment 46, EFW Flow.

D. Incorrect. OP-2202.002 directs using AFW pump 2P-75 to feed the SGs. Plausible because OP-2203.027, Loss of Main Feedwater Pump AOP, does direct attempting to restart tripped MFP (Step 3.B - Contingency Actions) and then if Reactor power greater than 4% and feedwater cannot be restored, then trip the Reactor and go to SPTAs. Since the stem indicates that the CRS has directed a Reactor trip, if can be assumed that MFP B was not able to be started and feedwater restored using a Main Feedwater Pump.

Question:

Consider the following:

- Unit 2 is operating at 60% power

- "A" MFP has been tagged out for bearing replacement

- Annunciator 2K03 A-11 "FEED PUMP TRIP" is in alarm for "B" MFP

- CRS directs tripping the Reactor

- SPTAs have been completed

- Control Room has been informed that "B" MFP was tripped inadvertently by maintenance personnel

- OP-2202.002, Reactor Trip Recovery EOP, has been entered Upon completion of OP-2202.002, S/G levels will be maintained at 60% by ______________________ .

A. 2P-7A Emergency Feedwater Pump B. 2P-7B Emergency Feedwater Pump C. 2P-75 Auxiliary Feedwater Pump D. 2P-1B Main Feedwater Pump Answer:

C. Correct Notes:

S/G levels will lower rapidly with a loss of both feed pumps ("A" OOS and "B" Tripped) the ACA will direct entry into Loss of Feed Pump AOP. Step 3 contingency actions does direct placing the tripped MFP (do not know reason why it tripped) in service or Trip the Rector (which is the action given in stem as directed by the CRS). SPTAs are entered and direct actuating EFW due to the lowering S/G levels (this will start both "A" and "B" EFW pumps). At the completion of SPTAs, all safety functions will be satisfied and RTR will be entered. RTR will restore S/G levels by placing AFW pump (2P-75) in service and securing both EFW pumps.

C. Correct: based on OP-2202.002 step 12.A A. B. and D. Incorrect due to procedural guidance to place the AFW pump in service to restore S/G levels OP-2202.002 step 12.A

- "A" and "B" Emergency Feedwater (EFW) pumps are running on recirculation Terminate/Throttle criteria has NOT been met for High Pressure Safety Injection [HPSI] due to _________________ .

A. Pressurizer level is too low B. Containment pressure is too high C. Feedwater flow to the S/Gs is too low D. Margin To Saturation (MTS) is too low Answer:

A. Correct Notes:

Containment is in a "Harsh Environment" condition (>200°F) which changes the values used to determine HPSI Terminate/Throttle criteria. (numbers to be used are bracketed) pressurizer level is required to be 50% or greater with the given conditions. Containment pressure is not included in the criteria to terminate HPSI. Steam Generator levels are adequate for HPSI termination. Margin to Saturation is greater than 30 degrees F which meets HPSI termination criteria.

Description:

Knowledge of the operational implications of the following concepts as they apply to Reactor Coolant Pump Malfunctions: - Natural circulation in a nuclear reactor power plant Question:

Consider the following:

- Unit 2 has been tripped from 100% power

- Reactor Coolant Pumps (RCPs) have been secured due to a power issue

- SPTAs are complete

- OP-2203.013, Natural Circulation AOP, is being implemented OP-2203.013 directs maintaing Margin to Saturation (MTS) ______ or greater to minimize reactor vessel head voiding. The Reactor Coolant System (RCS) is determined to be void free if Pressurizer level ____________ with Pressurizer spray in service.

A. 30°F; goes up B. 30°F; is stable C. 50°F; goes up D. 50°F; is stable Answer:

D. Correct Notes:

The Natural Circulation AOP requires a higher MTS [>50°F] step 5 and has the operator verify stable pressurizer level when Pzr spray is in service to check the RCS is void free. The Reactor Coolant Pumps malfunctioned due to a power issue and were secured. The operational implication is that the operators must recognize that while in the Natural Circulation AOP, the MTS minimum value is 50 degrees F. The operators must also know that head voiding is a concern while on natural circulation. So the question asks the operator how to recognize if the RCS is void free during natural circulation conditions by monitoring the Pressurizer level effects while Pressurizer spray is in service.

Description:

Knowledge of the operational implications of the following concepts as they apply to Loss of Reactor Coolant Makeup: - Relationship between charging flow and PZR level Question:

(REFERENCE PROVIDED)

Consider the following:

- Unit 2 is operating at 100% power

- Annunciator 2K12 B-3 "HEADER FLOW LO" comes into alarm

- Charging Header Flow (2FIS-4863) is reading 15 gpm

- Letdown Flow (2FIS-4802) is reading 26 gpm

- Pressurizer level is 60.0%

Assuming no further changes in charging or letdown flow and NO operator action, the first backup Charging Pump (CCP) would reach its auto start setpoint in approximately ______ minutes.

A. 7 B. 9.5 C. 11 D. 15 Answer:

C. Correct Notes:

Student should know that Pzr level setpoint is 60% at 100% power. Pzr level would decrease by 15 gpm with the stated conditions. 15 gpm in [from charging] minus (26 gpm out [from letdown] plus 4 gpm out [from controlled Bleedoff] ) equals -

15 gpm from the primary. Pzr level is 53.5 gallons per percent. 53.5 gal/% x 3.1% = 165.85 gallons required to be lost from the system to reach the 1st CCP auto start setpoint. [165.85 gals / 15 gpm = 11.06 minutes]

A. Incorrect: Number is based on using the VCT gallons per percent and accounting for RCP controlled Bleedoff flow: 15 gpm in [form charging] minus [(26 gpm out [from letdown] plus 4 gpm out [from controlled Bleedoff] )] = -15 gpm from the primary. VCT level is 33.8 gallons per percent. 33.8 gal/% x 3.1% = 104.78 gallons required to be lost from the system to reach the 1st CCP auto start setpoint.

[104.78 gals / 15 gpm = 6.98 minutes B. Incorrect: Number is based on using the VCT gallons per percent and not accounting for RCP controlled Bleedoff flow: 15 gpm in [form charging] minus [(26 gpm out [from letdown] ] = -11 gpm from the primary. VCT level is 33.8 gallons per percent. 33.8 gal/% x 3.1% = 104.78 gallons required to be lost from the system to reach the 1st CCP auto start setpoint. [104.78 gals / 11 gpm = 9.5 minutes D. Incorrect: Number is based on using the Pzr gallons per percent and not accounting for RCP controlled Bleedoff flow: 15 gpm in [form charging] minus (26 gpm out [from letdown] = -11 gpm from the primary.

Description:

Knowledge of the reasons for the following responses as they apply to the Loss of Component Cooling Water: - The automatic actions (alignments) within the CCWS resulting from the actuation of the ESFAS Question:

The PURPOSE for the CCW/ACW Return Isolation Valves (2CV-1543-1/2CV-1542-2) to automatically A. open on a Main Steam Isolation Signal (MSIS) to ensure cooling to the RCP seals is maintained B. open on a Main Steam Isolation Signal (MSIS) to cross-tie Loop 1 and Loop 2 Service Water returns C. close on a Main Steam Isolation Signal (MSIS) to separate Loop 1 and Loop 2 Service Water returns D. close on a Main Steam Isolation Signal (MSIS) to isolate seismic Category 1 piping from seismic Category 2 piping Answer:

D. Correct Notes:

D. Correct: MSIS and SIAS will CLOSE the inlets and outlets to CCW system to separate it from the Service Water system. SW provides cooling to components that are not safety related and therefore not seismic category 1. MSIS separates the seismic category 1 piping from the seismic category 2 piping.

A. Incorrect: MSIS will close 2CV-1543-1 and 2CV-1542-2. These valves are normally open to provide SW return flow from the CCW Heat Exchangers and the Main Chiller condensers to the SW return header. SW provides cooling to the CCW Heat Exchangers which provides cooling to the RCP seals.

B. Incorrect: MSIS will close 2CV-1543-1 and 2CV-1542-2. Loop 1 and Loop 2 Service Water returns are crosstied during an MSIS actuation via the Emergency Cooling Pond return valves.

C. Incorrect: MSIS will close 2CV-1543-1 and 2CV-1542-2, so the first half of the answer is correct. But Loop 1 and 2 Service Water return headers will still be crossed tied with these return valves closed via the Emergency Cooling Pond return valves.

A. These conditions would cause two Reactor trip circuit breakers to open AND NO Reactor trip B. These conditions would cause four Reactor trip circuit breakers to open AND a Reactor trip C. These conditions would cause only the #1' CEA MG Set output contactor to open AND NO Reactor trip D. These conditions would cause the #1 and #2 CEA MG Set output contactors to open AND a Reactor trip Answer:

D. Correct Notes:

D. Correct: These conditions would cause the 'A' and 'B' CEA MG Set output contactors to open AND a Reactor Trip.

A. Incorrect: These pressure transmitters are independent of the pressure transmitters that feed RPS and Reactor trip breakers would not open initially but all 8 circuit breakers eventually would trip open due to LPD and DNBR trips.

B. Incorrect: Same reason as above C. Incorrect 2 out of 4 ATWS pressure transmitters failing high will give a full output opening both disconnect contactors causing a Reactor trip

Consider the following:

- A Steam Line Break has occurred on the B Steam Generator (S/G) outside Containment

- Main Steam Isolation (MSIS) has automatically actuated

- OP-2205.005, Excess Steam Demand EOP, has been entered

- B Steam Generator (S/G) level indicates 0 (zero) wide range

- RCS Tcold has been stabilized at 398oF using the A S/G

- RCS Thot has been stabilized at 400oF using the A S/G

- Average CET temperature indicates 400oF In accordance with OP-2202.010, Standard Attachments, to prevent pressurized thermal shock (PTS) from causing brittle fracture of the Reactor Vessel, RCS pressure should be reduced below ________ psia using ______ spray.

A. 1540 ; Aux B. 1540 ; Main C. 1800 ; Aux D. 1800 ; Main Proposed Answer: __B:__1540; Main__

Explanation:

A. Correct pressure but incorrect spray. With the rupture outside containment but upstream of the MSIV, RCPs would still be running and Main spray is available and it would be used by procedure.

B. Correct pressure and correct spray. Using OP-2202.10, Standard Attachments, Attachment 1, P-T Limits, the second bullet states Use 200oF MTS line for PTS limit for uncontrolled RCS cooldown below 500oF Tcold. With conditions given in the stem, this line is the one to be used.

The bullet also directs use of RCS Thot in forced circulation to determine RCS MTS. Given in the stem, Thot is stabilized at 400oF. Using line B on the graph, 400oF RCS temperature correlates to 1540 psia. Since RCPs would still be running, use of Main spray is correct.

C. Incorrect pressure and incorrect spray. 1800 psia is plausible because it is the value that correlates to 400oF RCS temperature if the applicant incorrectly uses dashed curve D, PRI/SEC S/G DP LIMIT. Since RCPs would still be running, Aux spray is incorrect.

D. Incorrect pressure and correct spray. 1800 psia is plausible because it is the value that correlates to 400oF RCS temperature if the applicant incorrectly uses dashed curve D, PRI/SEC S/G DP LIMIT. Since RCPs would still be running, Main spray is correct.

- Unit 2 has tripped due to high Containment Building pressure

- Containment Building pressure is 24 psia and trending up

- Annunciator 2K01 B-7 LO RELAY TRIP for 2A1 is in alarm

- Neither.

- A Steam Generator.

- B Steam

- SPTAs have been completed RCS cooling would be accomplished from the Control Room by starting ________Condensate Pump because _______________.

A. A (2P-2A); there is no control power for the B pump B. B (2P-2B); the MFIW signal cannot be overridden for the A pump C. C (2P-2C); the MFIW signal cannot be overridden for the D pump D. D (2P-2D); there is no control power for the B pump Proposed Answer: __D_

Explanation:

Distracters A and C are not correct because condensate pumps A and C are both powered by 2A1, which has a lockout on the bus and the second part of the distracter is not needed. For distracter B although it is correct that the MFIW signal cannot be overridden for the A pump (second part is true) the B pump has no DC control power because of (ANO put in reason here)and therefore cannot be started from the control room.

This makes D the only correct answer for both parts and involves knowledge of the interlocks and features from the control room ANO please verify this is correct!

Consider the following:

- Unit 2 has tripped due to high Containment Building pressure

- Containment Building pressure is 24 psia and trending up

- Annunciator 2K01 B-7 "LO RELAY TRIP" for 2A1 is in alarm

- Neither Emergency Feedwater (EFW) pump is available

- "A" Steam Generator (S/G) Level is 200" (WR) and trending down

- "B" Steam Generator (S/G) Level is 21% (NR) and trending down slowly

- SPTAs have been completed RCS cooling would be accomplished by starting ______ Condensate Pump from the Control Room.

A. "A" (2P-2A)

B. "B" (2P-2B)

C. "C" (2P-2C)

D. "D" (2P-2D)

Answer:

D. Correct Notes:

D. Correct: For the given conditions, a SIAS, CCAS, EFAS, CSAS, and a MSIS are all present. The CSAS and MSIS signals, along with the MFWIS, will isolate feed and steam to/from the containment to minimize the energy release into containment. OP-2202.009, Functional Recovery EOP, would be entered due to 2 events in progress (ESD and Loss of Feedwater) Normally the EFW pumps would supply feedwater for RCS heat removal but they are unavailable. AFW pump is powered from 2A1 is unavailable. The Functional would direct over riding the MFWIS signal on either the "B" or "C" condensate pumps by opening the control power breakers. This action makes the "B" and "C" Condensate Pumps unavailable to be started from the Control Room. "A" Condensate Pump is not available due to 2A1 being locked out. So the only remaining option is to start "D" Condensate pump from the Control Room.

A. Incorrect: "A" Condensate pump is unavailable because 2A1 is locked out.

B. Incorrect: "B" Condensate pump is unavailable because it has not control power. The action in the EOP to open "B" and "C" Condensate Pump control power breakers made "B" unavailable for start from the Control Room.

C. Incorrect: "C" Condensate Pump is unavailable because 2A1 is locked out.

Description:

Ability to determine and interpret the following as they apply to the Loss of Vital AC Instrument Bus: - ESF system panel alarm annunciators and channel status indicators Question:

Consider the following:

- Unit 2 is at 100% power

- Annunciator 2K01-F10, "2RS1 INVERTER TROUBLE" comes into alarm

- Annunciator 2K01-J10, "DIST PNLS 2RS1/2RS3 GROUND" comes into alarm

- 2RS-1, 120 Vital AC Bus, voltage is reading 0 volts on SPDS As the RO you are asked by the CRS to verify status of ESFAS channels at Panel 2C03. Based on the above plant status, you expect _______________.

A. only Trip Path-1 status lights to be out B. only Trip Path-2 status lights to be out C. Trip Path-1 and Trip Path-3 status light to be out D. Trip Path-2 and Trip Path-4 status lights to be out Answer:

C. Correct Notes:

2RS-1 powers the RED train (channel 1) components. Each Logic Matrix has 2 individual 12v power supply, powered by a different vital bus. A failure of 2RS-1 would cause one side of the AB Logic Matrix ladder, which would cause the AB1 and AB3 Logic Matrix relays to de-energized. This causes the AB1 contact in the Trip Path-1 circuit to open which de-energizes the Trip Path-1 circuit and makes the indication light on 2C03 go out. The AB3 contact will also open in the Trip Path-3 circuit, which causes the Trip Path-3 circuit to de-energized and the status light on 2C03 will go out.

- All other systems and components operate as designed

- The CRS has entered OP-2203.037, Loss of 125 VDC AOP In accordance with OP-2203.037, the CRS would direct placing ALL points on EITHER _________________________ in bypass to prevent ________________________.

A. channel 1 (2C23-1) OR channel 2 (2C23-2); inadvertent Reactor trip B. channel 1 (2C23-1) OR channel 3 (2C23-3); inadvertent Reactor trip C. channel 1 (2C23-1) OR channel 2 (2C23-2); inadvertent actuations if the Reactor were to trip D. channel 1 (2C23-1) OR channel 3 (2C23-3); inadvertent actuations if the Reactor were to trip Answer:

D. Correct Notes:

D. Correct: The loss of 125VDC AOP will direct bypassing all points in either Channel 1 or Channel 3 to prevent inadvertent actuations of Green train components. If this action were not performed and the Reactor were to trip, both red train Vital AC buses would be de-energized causing actuations on the ESFAS actuations that come in when the parameter is low.

A. Incorrect: The Reactor will not inadvertently trip because the Inverters swap to Alternate Source when the Charger trips.

B. Incorrect: The Reactor will not inadvertently trip because the Inverters swap to Alternate Source when the Charger trips.

C. Incorrect: The Loss of 125V DC AOP instructs the operators to bypass all point on Channel 1 or Channel 3. Channel 2 is powered from the DC train that still has power.

A. open; open B. open; closed C. closed; open D. closed; closed Answer:

A. Correct Notes:

A Safety Injection Actuation (SIAS) occurs when RCS pressure drops below 1650#. The SIAS will start the LPSI pumps and open the injection MOVs to the RCS. The LPSI pump recirc flowpath is aligned to the RWT, if a Recirc Actuation Signal (RAS) occurred the LPSI pump is tripped and the recirc flowpath valves would go closed, isolating the LPSI recirc flowpath from the RWT. A RAS is not actuated based on the time given [15 minutes] the RWT holds enough inventory to supply the ECCS pumps for 30 minutes during a DBA. The given conditions does not indicate a DBA in progress [RCS pressure 1400#

and slowly trending down] therefore the LPSI recirc flowpath valves to the RWT are open.

Answer:

A. Correct Notes:

A: Correct. An Inadvertent SIAS will cause the SW to ACW Supply Isolation Valves to close. These valves have to be overridden and opened to prevent a Turbine Runback and is directed early on in the AOP.

B: Incorrect. SIAS does not automatically close the CCW isolation valves to the containment building.

These will not have to be opened during an Inadvertent SIAS condition.

C. Incorrect. The inside Containment Sump Suction Isolation Valves are normally open and do not receive an SIAS. They do receive a RAS and the Inadvertent RAS AOP directs overridding and closing these valves during an Inadvertent RAS. This action is done in the Inadvertent RAS AOP to prevent draining the RWT to the Containment Sump.

D. Incorrect. The Containment Spray Pumps do not receive a SIAS and will not have to be secured during an Inadvertent SIAS.

Q38_R1: NRC comments Upon further review of the question and KA, the proposed question is not a good match to the KA.

The KA is asking for knowledge of the effect of a loss or malfunction of ESFAS on the fuel. The question, as proposed, is asking for knowledge of the design requirements of a system that is actuated by an ESFAS signal in response to a design basis LOCA (where the system design is to provide for core cooling that is indirectly related to the KA).

A better KA match would be a question that asks what would be the effect of failure of the ESFAS to generate an actuation signal(s) whose purpose is to protect the fuel.

For example - feel free to develop another question Which ESFAS signal(s), if not generated, would have the effect of more extensive core damage?

A. Only SIAS B. SIAS and CIAS C. CIAS and CSAS D. EFAS, SIAS and RAS The Lesson Plan should be the one used to teach ESFAS and the Reference should be STM 2-70, ESFAS.

Knowledge of CSS design feature(s) and/or interlock(s) which provide for the following: - Automatic swapover to containment sump suction for recirculation phase after LOCA (RWST low-low level alarm)

Question:

Consider the following:

- Unit 2 has tripped due to a Design Based Accident (DBA) LOCA

- One (1) hour has elapsed The suction source for the running Emergency Core Cooling Systems (ECCS) pumps is aligned to ____________________

and adequate core heat removal would be verified using _______________ .

A. Refueling Water Tank (RWT); Exhibit 2, HPSI Flow Curve B. Refueling Water Tank (RWT); Exhibit 3, LPSI Flow Curve C. Containment sump; Exhibit 2, HPSI Flow Curve D. Containment sump; Exhibit 3, LPSI Flow Curve Answer:

C. Correct Notes:

The RWT inventory will be transferred into the containment building in approximately 30 minutes following the Design Based Accident (DBA) LOCA. When RWT level reaches 6% (RAS actuation setpoint) the ECCS suction header automatically swaps to the containment sump. The LPSI pumps will trip on the RAS to prevent pump damage and cavitation of the HPSI and Spray pumps due to the LPSI high flowrate. LPSI pumps cannot be restarted unless RAS is reset or leads are lifted.

Exhibit 2 shows the expected flow for given RCS pressure that is required for Inventory and Heat Removal.

Consider the following:

- Unit 2 is recovering from a complete loss of feedwater event

- 2P-7B is out of service for maintenance

- "A" S/G level 12% trending down

- "B" S/G level 19% trending down

A. damaging the feed ring; throttling the injection valves B. damaging the feed ring; controlling pump speed C. overcooling the RCS; throttling the injection valves D. overcooling the RCS; controlling pump speed Answer:

B. Correct Notes:

With S/G level <49%, the feed ring is uncovered and the water will flash to steam. There is a possibility of collapsing the feed ring when cold feed water is restored. The EOP direct controlling feedwater flow to <150 gpm to minimize the chance of feed ring damage. 2P-7A is the steam driven EFW pump and its S/G feed injection valves are not throttlable. The EOP directs controlling pump speed to control feed rate. This scenario also assumes 2P-7B is out of service and not available to start. 2P-7B is normally the first choice when restoring feedwater in a loss of feedwater event.

Q44_R1 (NRC proposed changes to Rev1)

Proposed Question:

Consider the following:

- Unit 2 has completed a plant startup and is raising power

- Current power is 5% and trending up

- "A" and "C" Condensate Pumps (2P-2A and 2P-2C) are running

A. automatically maintain Steam Generator levels at setpoint; place B Main Feedwater pump (2P-1B) in service B. automatically maintain Steam Generator levels at setpoint; attempt to restart A Main Feedwater pump (2P-1A)

C. require manual operator action to restore Steam Generator levels to setpoint; place B Main Feedwater pump (2P-1B) in service D. require manual operator action to restore Steam Generator levels to setpoint; attempt to restart A Main Feedwater pump (2P-1A)

Proposed Answer: __C.__

Explanation:

C. Correct. The FWCS will open the MFRV's to try and restore level, but 2P-75 will not provide enough flow to restore SG level at 5% power. Per the Contingency Actions in OP-2203.027, it will only provide enough flow for 4% power. Therefore, manual operator action is required to restore levels to setpoint. In OP-2203.027, the Contingency Actions for Check at least ONE

MFW pump operating, the steps are lettered, not bulleted. Therefore, the actions have to be performed in order. The first action is to attempt to place the standby MFW pump in service.

Therefore, B Main Feedwater pump (2P-1B) would be placed in service.

A. Incorrect. Although OP-2203.027 requires placing 2P-1B in service first, the FWCS, with the feedwater supply from 2P-75, would not be able to automatically control level.

B. Incorrect. The FWCS, with 2P-75, would not be able to automatically control level. In addition, attempting to start the tripped MFP is the second prioritized action in OP-2203.027, Contingency Action 3.

D. Incorrect. Although manual operator action is required, the action cited from OP-2203.027 is the secondary action.

Q48_R1 (NRC proposed changes to Rev1)

Original comments stated that question was classified as unsatisfactory because of its faulted 2x2 logic (an applicant could get the correct answer without having knowledge to answer both parts of the question). Revision 1 provided by the licensee did not address this issue.

A question in the correct format is proposed as follows:

Proposed Question:

Consider the following:

- Unit 2 has tripped from 100% power due to a large break LOCA

- Annunciator 2K09 B-3 "2A4 L.O. RELAY TRIP" is in alarm

- Containment pressure is 25 psia and trending up

- Annunciator 2K06 A-1 "2P-35A FAILURE ON ESFAS" is in alarm OP-2203.012F, Annunciator Corrective Actions for 2K06 A-1 __(1)_____ "A" Containment Spray pump (2P-35A) to be started without assessment because (2) .

________(1)_________ (2)_____________

A. directs EDG #1 is supplying power to its safety bus B. directs the Core Heat Removal safety function is not met C. prohibits EDG #1 is supplying power to its safety bus D. prohibits the Core Heat Removal safety function is not met Proposed Answer: __B__

Explanation:

B. Correct: To determine the correct answer, the applicant has to determine the effects of the 2A4 bus lockout during the LOCA. With the LOCA, ESFAS would start both EDGs. The 2A4 bus lockout prevents EDG #2 and offsite power from supplying this bus. EDG #1 has started, but with offsite power available, offsite power will continue to supply power to bus 2A3.

Procedure OP-2203.012F, ACA for 2K06 A-1, Step 2.3.1, directs the start of 2P-35A without assessment. The basis for this is provided in procedure COPD-032, Section 9.3. With offsite powered to a bus supplying a component that failed to automatically actuate, it directs that one attempt to start the component be attempted. This is because the safety function that the component addresses is not being fulfilled. With no Containment Spray pumps running, the Containment Heat Removal safety function is not being met. See the Note prior to Step 2.2 in procedure OP-2203.012F, ACA for 2K06 A-1.

A. Incorrect: It is true that starting 2P-35A is directed, but it is not because EDG #1is supplying power to its safety bus. Offsite power is being supplied to the safety bus.

C. Incorrect: Due to the situation, an attempted start of 2P-35A is directed. In addition, the electrical supply to the Red Train safety bus is offsite power.

D. Incorrect: Due to the situation, an attempted start of 2P-35A is directed. It is plausible that an assessment could be required prior to meeting the safety function. For example, if EDG #1 was supplying its safety bus, even with the Containment Heat Removal safety function not met, an assessment would be required per procedure COPD-032, Section 9.3, second bullet.

Description:

Knowledge of D.C. Electrical System design feature(s) and/or interlock(s) which provide for the following: -

Breaker interlocks, permissives, bypasses and cross-ties Question:

Consider the following:

- Unit 2 is operating at 100% power

- DC control power has been lost to the 2A2 non-vital 4160 V bus Which of the following would describe the operation of the breakers on 2A2?

A. Breakers would trip open and operation would only be possible by local manual means B. Breakers would be able to be operated remotely but automatic trip functions would not be functional C. Breakers will remain in their "as is" condition and operation would only be possible by local manual means D. Automatic breaker trips would remain functional but remote operation of breakers would not be possible Answer:

C. Correct Notes:

C. Correct: 125 VDC power provides the motive power for remote breaker operations and permissives, and breaker bypass interlocks. This would prevent any remote manual operations and automatic breaker cycles.

A. Incorrect: Tripping breakers open requires 125 VDC power B. Incorrect: There are no remote operations without DC control power D. Incorrect: For both reasons above

Form ES-401-5 Written Exam Question Worksheet 62

Comments on Question 49, Revision 1 The change did not address the concern.

The basis for the proposed correct answer says that the loss of 125 VDC control power prevents any remote manual operations. Based on Answer Cs wording, local manual means must be available as the only option for operating the affected breakers.

When the wording of distracter B is reviewed, it says Breakers would be able to be operated remotely.. Is operating a breaker by local manual means, considered remotely? An applicant could argue if this is vague that operating the breaker by local manual means can be completed outside the Control Room, so it is remote. If there is a specific site definition for remotely that will ensure that distracter B is not correct, it needs to be documented in the question notes. If there isnt a basis, the next best thing would be to modify distracter B to say Breakers would be able to be manually operated remotely,..

The goal is to have all the terms clear so that there is no room to argue that there are two correct answers.

A. rise; manually throttle B. rise, manually close C. lower, manually throttle D. lower, manually close Answer:

A. Correct Notes:

A. Correct. Second stage heating comes from Main Steam. When the RSLLV fails full open, it causes more Main Steam flow to go to the second stage heating coil, which causes MSR outlet temperature to go up. Attachment F contains instructions to throttle the RSLLV to prevent large temperature mismatches on the Low Pressure Turbine inlets.

B. Incorrect. Fully closing the RSLLV will isolate steam to the 2nd stage heating coil for the MSR causing Low Pressure Turbine inlet temperature to go to low and would cause a temperature mismatch.

C. Incorrect. Low pressure turbine inlet temperature would go up, not go down.

D. Incorrect. Low pressure turbine inlet temperature would go up, not go down.

B. Correct Notes:

The LRW/BMS Process Radiation Monitor, 2RITS-2330, provides an automatic closure of 2CV-2330A and/or 2CV-2330B.

This automatic feature occurs on a high alarm that is determined by the Unit 2 Liquid Radwaste Release Permit (OP-2104.014, Supp 1). Going to PULSE Cal will raise the detector radiation output above the alarm setpoint causing the valves to go closed. Testing of this interlock will prevent discharging liquid waste above the design limits.

Question 64_R0 (NRC recommendations)

Revised Question:

Consider the following:

• Unit 2 is operating at 97% power

• OP-2106.009, Supplement 3, Turbine Generator Valve Stroke Test surveillance is in progress OP-2106.009 directs placing first stage pressure feedback in service because first stage pressure feedback ____(1)____. If first stage pressure feedback is NOT placed in service, when stroking a high pressure turbine control valve closed the reactor coolant system temperature initially ____(2)____.

A. (1) will open the other high pressure turbine control valves to compensate for the closure of the tested high pressure turbine control valve (2) increases B. (1) will open the other high pressure turbine control valves to compensate for the closure of the tested high pressure turbine control valve (2) remains the same C. (1) will lock the other high pressure turbine control valves in place and uses steam bypass valves to compensate for closure of the tested high pressure turbine control valve (2) increases D. (1) will lock the other high pressure turbine control valves in place and uses steam bypass valves to compensate for closure of the tested high pressure turbine control valve (2) remains the same Comments: Per procedure 2106.009, first stage pressure feedback opens the other high pressure turbine control valves to maintain turbine load NEAR pre-test values. Due to stroke time, the opening of the other high pressure turbine control valves is slightly delayed. Therefore the RCS temperature will initially increase due to the lower steam demand versus steam supply, resulting in less heat transfer in the steam generators and a high reactor coolant system temperature. This makes answer A correct. Distractor B is incorrect but plausible if the candidate does not take into account the delayed response of the other high pressure turbine control valves. Distractors C and D are incorrect because first stage pressure feedback opens the other control valves, not steam dumps, but is plausible because the procedure has instructions for using steam dumps to maintain the power level constant while reducing turbine load.

Description:

Knowledge of the physical connections and/or cause-effect relationships between the MT/G System and the following systems: - RCS, during steam valve test Question:

Consider the following:

- Unit 2 is operating at 97% power

- OP-2106.009, Supplement 3, Turbine Generator Valve Stroke Test surveillance is in progress OP-2106.009 directs placing first stage pressure feedback in service because first stage pressure feedback

______________. If first stage pressure feedback is NOT placed in service, when stroking a high pressure turbine control valve CLOSED the RCS temperature initially ______________.

A. will open the other high pressure turbine control valves to compensate for the closure of the tested high pressure turbine control valve; increases B. will open the other high pressure turbine control valves to compensate for the closure of the tested high pressure turbine control valve; remains the same C. will lock the other high pressure turbine control valves in place and uses steam bypass valves to compensate for closure of the tested high pressure turbine control valve; increases D. will lock the other high pressure turbine control valves in place and uses steam bypass valves to compensate for closure of the tested high pressure turbine control valve; remains the same Answer:

A. Correct Notes:

A. Correct. Per procedure OP-2106.009, first stage pressure feedback opens the other high pressure turbine control valves to maintain turbine load NEAR pre-test values. Due to stroke time, the opening of the other high pressure turbine control valves is slightly delayed. Therefore the RCS temperature will initially increase due to the lower steam demand versus steam supply, resulting in less heat transfer in the steam generators and a high RCS temperature.

B. Incorrect. Plausible if the candidate does not take into account the delayed response of the other high pressure turbine control valves.

C. Incorrect. First stage pressure feedback opens the other control valves, not steam dumps but is plausible because the procedure has instructions for using steam dumps to maintain the power level constant while reducing turbine load.

Description:

Emergency Procedures/Plan - Knowledge of the organization of the operating procedures network for normal, abnormal, and emergency evolutions.

Question:

Abnormal operating procedures (AOPs), and Emergency operating procedures (EOPs) will give direction to "GO TO" another AOP, EOP or normal operating procedure (NOP).

Which of the following describes the term "GO TO"?

A. Continue with the controlling procedure and perform the procedure that you are directed to "GO TO" in conjunction with it B. Complete the controlling procedure and then enter the procedure that you were directed to "GO TO" C. Immediately exit the controlling procedure and then enter the procedure that you were directed to "GO TO" D. Exit the controlling procedure when plant conditions allow, then enter the procedure that you were directed to "GO TO" Answer:

C. Correct Notes:

ANO-2 EOP/AOP User Guide uses the term "GO TO" to depart from the current procedure or step in the procedure and enter either another step in the current procedure or a different procedure altogether. It is used when the current procedure or step is not working and will help the implementer with plant conditions and direct entry into a procedure that will help.

Question 75_R0 (NRC recommendations)

Revised Question:

Consider the following:

• Unit 2 is operating at 100% power

• An Annunciator check is being performed for the shift turnover checklist

• Alarm panels 2K01 through 2K07 do not alarm

• OP-2203.042, Loss of Annunciators AOP, has been entered In accordance with OP-2203.042, the operators would ______.

A. maintain steady state plant conditions.

B. perform a one (1) hour rapid plant shutdown.

C. perform a two (2) hour normal plant shutdown.

D. trip the plant and enter the SPTAs.

Comments: The original question asked what the CRS would do, which does not provide a good legal basis for the question and answers, so the revised question ties the answers to what the procedure would direct based on the initial conditions, which provides the necessary legal basis.

Question:

Consider the following

- Unit 2 is at 100% power

- No annunciators will alarm on Annunciator panels 2K01 thru 2K12

- OP-2203.042, Loss of Annunciators AOP, has been entered Per OP-2203.042, the required action is to _______________.

A. immediately commence a plant shutdown due to the inability to monitor the plant B. maintain steady state plant conditions due to the inability to monitor the plant C. immediately commence a plant shutdown due to the loss of COLSS D. maintain steady state plant conditions due to the loss of COLSS Answer:

B. Correct Notes:

2K01 thru 2K12 are all the annunciators on the front panels.

B. Correct: Plant maneuvers are not recommended or required without remote monitoring capability (annunciators) steady state plant operation is preferred.

A. Incorrect: An immediate plant shutdown is not directed by the AOP. A plant maneuver could be required per Tech Specs, but not in this case.

C. Incorrect: An immediate plant shutdown is not directed by the AOP. A plant maneuver could be required per Tech Specs, but not in this case.

D. Incorrect. The AOP does require the plant to be maintained at steady state plant conditions, but COLSS is not lost, just the ability to continuously monitor COLSS. The required action is for the operators to continuously monitor COLSS on the plant computer.

Question 75_R1 (NRC recommendations)

Revised Question:

Consider the following:

- Unit 2 downpower is planned for surveillance testing

- Annunciator check is being performed for the shift turnover checklist

- Alarm panels 2K01 through 2K07 do not alarm

- OP-2203.042, Loss of Annunciators AOP, has been entered In accordance with OP-2203.042, the operators would ________. The fault __________

propagate to other alarm panels.

A. not perform the downpower; could B. not perform the downpower; could not C. use alternate indications to perform the downpower; could D. use alternate indication to perform the downpower; could not Answer: A Comments: The original question asked what the CRS would do, which does not provide a good legal basis for the question and answers, so the revised question ties the answers to what the procedure would direct based on the initial conditions, which provides the necessary legal basis. Also, by altering the stem to include a downpower, it provides the opportunity to test the applicants on whether or not the downpower could continue, which the AOP does not allow, except in the case of exceeding Technical Specification limits.

Since the downpower is for a surveillance, there is no indication of exceeding a Technical Specification limit, so the downpower would not be performed. The procedure does allow operators to downpower using alternate indications if a limit is exceeded, so this makes distractors C and D plausible but incorrect. The second piece is a caution from the AOP, which states that fault may propagate from 2K01 through 2K12, making answer A correct. Distractor B is plausible if the applicant cannot remember if the alarms are all on the same circuit.

Description:

Ability to determine and interpret the following as they apply to a small break LOCA: - Whether PZR water inventory loss is imminent Question:

(REFERENCE PROVIDED)

Consider the following:

- Unit 2 is operating at 100% power

- "C" HPSI pump (2P-89C) is OOS for maintenance

- "C" CCP (2P-36C) is aligned to Green

- ATC reports Containment parameters are trending up (pressure, temperature, radition, and humidity)

- Pressurizer level is 60%

- Volume Control Tank (VCT) level is 72%

3 minutes later:

- Pressurizer level is 59%

- VCT level is 71%

Unit 2 now trips due to a Loss of Offsite Power (LOOP)

- Annunciator 2K08 C-2 "ENGINE/EXCITER SHUTDOWN" for #1 EDG is in alarm

- CBOT reports "B" HPSI pump is running without discharge pressure

- RCS Leakrate does not change post trip Based on conditions above, the Reactor Coolant System (RCS) inventory (Pressurizer level) ________ recover (trend up) and after performing SPTAs, the CRS would diagnose entry into _________________________________.

A. would; OP-2203.016, Excess RCS Leakage B. would; OP-2202.003, Loss of Coolant Accident C. would not; OP-2203.016, Excess RCS Leakage D. would not; OP-2202.003, Loss of Coolant Accident Answer:

B. Correct Notes:

The leakrate is based on 55.3 gallons per percent in the pressurizer x 1% change in level = 55.3 gallons 33.8 gallons per percent in the VCT x 1% change in level = 33.8 gallons, 55.3 + 33.8 = 89.1 gallons / 3 minutes (time frame the leakrate data was taken) = 29.7 gallon/minutes RCS leakage. SIAS would be actuated due to the RCS leakage and with the loss of offsite power (LOOP) and the #1 EDG not supplying the bus (exciter shutdown) only Green Train components will be available for makeup sources. With the "C" HPSI (swing) pump OOS and the failure of the "B HPSI pump the 2 CCPs (with a capacity of 44 gpm each) would be available to makeup to the Pressurizer (the "B" LPSI pump would be running but RCS pressure would Form ES-401-5 Written Exam Question Worksheet 92

Data for 2014 NRC RO/SRO Exam 30-Jan-14 be to high for injection (RCS makeup > RSC leakage) therefore Pressurizer level would trend up at approximately 1% /

minute. With a leakrate of 29.7 gpm entry conditions for OP-2203.016, Excess RCS Leakage. Exhibit 8 will direct the CRS to diagnose LOCA due to a RCS leak with a LOOP.

A. Incorrect. Pressurizer level would be trending up, but it is incorrect to diagnose Excess RCS leakage AOP. Per Exhibit 8 of Standard Attachments, when an AOP is combined with a LOOP, the associated EOP is diagnosed, which is the LOCA EOP.

Plausible because the Excess RCS Leakage AOP could be diagnosed coming out of Standard Post Trip Actions B. Correct. Pressurizer level would be recovering and per Standard Attachments Exhibit 8, Excess RCS Leakage AOP plus a LOOP EOP results in a diagnosis of the LOCA EOP.

C. Incorrect. Per the calculation above, Pressurizer level would be recovering not going down. Plausible because the candidate could calculate the wrong leakrate.

D. Incorrect. Per the calculation above, Pressurizer level would be recovering not going down. Plausible because the candidate could calculate the wrong leakrate.

Consider the following:

- Unit 2 has tripped from 100% power

- RCS pressure is 1800 psia and lowering

- Containment pressure is trending up

- Containment High Range Radiation Monitors are in alarm and rising

- Containment Low Range Radiation Monitors are reading 10 mr/hr and stable

- 'A' SG level is 18%

C. Correct Notes:

A. Incorrect. LOCA EOP would not be diagnosed in this scenario because the Containment Low Range Radiation Monitors are reading normal and stable and 'A' SG pressure is lowering. The Containment High Range Radiation Monitors are in alarm and rising, which could distract the applicant, but the coaxial cables for these radiation monitors have been susceptible to thermally induced currents which make them read false high during an ESD. Plausible because all the other indications are consistent with a LOCA.

B. Incorrect. LOCA EOP would not be diagnosed in this scenario because the Containment Low Range Radiation Monitors are reading normal and stable and 'A' SG pressure is lowering. The Containment High Range Radiation Monitors are in alarm and rising, which could distract the applicant, but the coaxial cables for these radiation monitors have been susceptible to thermally induced currents which make them read false high during an ESD. Plausible because all the other indications are consistent with a LOCA.

Form ES-401-5 Written Exam Question Worksheet 94

Data for 2014 NRC RO/SRO Exam 30-Jan-14 C. Correct. ESD EOP diagnosis is correct based on lowering RCS pressure, Containment Low Range Radiation Monitors stable, and 'A' SG pressure trending down. MSIS actuates at 751 psia. Both Steam Generators will be fed by EFW until 751 psia is reached. At that point, the EFAS initiation logic would isolate EFW flow to the affected SG 'A'. SG 'B' would continue to be fed by EFW.

D. Incorrect. ESD EOP diagnosis is correct based on lowering RCS pressure, Containment Low Range Radiation Monitors stable, and 'A' SG pressure trending down. MSIS actuates at 751 psia. Both Steam Generators will be fed by EFW until 751 psia is reached. At that point, the EFAS initiation logic would isolate EFW flow to the affected SG 'A'. SG 'B' would continue to be fed by EFW. So what makes this distractor incorrect is that 'A' SG would not be fed with pressure less than 751 psia.

Plausible because 'A' SG would be fed until 751 psia is reached and then it would be isolated by the EFAS initiation logic.

B. OP-2202.007, Loss of Offsite Power EOP; Volume Control Tank (VCT)

C. OP-2202.008, Station Blackout EOP; Quench Tank (QT);

D. OP-2202.008, Station Blackout EOP; Volume Control Tank (VCT)

Answer:

C. Correct Notes:

The student should recognize a Station Blackout is in progress (due to the LOOP, AACDG OOS and neither EDG starting)

The CRS would diagnose the Station Blackout EOP using Standard Attachments Exhibit 8, Diagnosis Flow Chart. Without power to the non-vital buses, there would be no Instrument Air pressure and the CBO flowpath to the VCT would isolate (valves fail close) which will align CBO to the QT through the CBO relief valve.

A. Incorrect. Because neither EDG could be started during SPTAs and the AAC DG is unavailable, both 2A3 and 2A4 are de-energized. This meets the entry conditions for the SBO EOP. Plausible because a LOOP does exist in the stem of the question.

B. Incorrect. Because neither EDG could be started during SPTAs and the AAC DG is unavailable, both 2A3 and 2A4 are de-energized. This meets the entry conditions for the SBO EOP. Plausible because a LOOP does exist in the stem of the question.

C. Correct. Because neither EDG could be started during SPTAs and the AAC DG is unavailable, both 2A3 and 2A4 are de-energized. This meets the entry conditions for the SBO EOP. Without power to the non-vital buses, there would be no Instrument Air pressure and the CBO flowpath to the VCT would isolate (valves fail close) which will align CBO to the QT through the CBO relief valve.

Form ES-401-5 Written Exam Question Worksheet 96

Data for 2014 NRC RO/SRO Exam 30-Jan-14 D. Incorrect. Without power to the non-vital buses, there would be no Instrument Air pressure and the CBO flowpath to the VCT would isolate (valves fail close) which will align CBO to the QT through the CBO relief valve. Plausible because CBO is aligned to the VCT prior to the power failure and the power failure results in CBO being realigned to the QT.

Consider the following:

- Unit 2 is operating at 100% power

- 2D02 Green Battery disconnect has been opened for maintenance

- Battery charger, 2D-32B, is in service

- Now 2D-32B the output breaker trips open The CRS would diagnose entry into ______________________________ and Pressurizer level would be maintained by cycling a Coolant Charging Pump (CCP) due to ______________ letdown isolation valve failing closed.

A. OP-2202.001, Standard Post Trip Action EOP; 2CV-4820-2, inside containment B. OP-2202.001, Standard Post Trip Action EOP; 2CV-4823-2 outside containment C. OP-2203.037, Loss of 125V DC AOP; 2CV-4820-2, inside containment D. OP-2203.037, Loss of 125V DC AOP; 2CV-4823-2, outside containment Answer:

D. Correct Notes:

With the Green Battery disconnected from its bus [2D02] the battery charger is supplying all green DC loads. When the chargers breaker trips open, a loss of green DC will occur. The unit will stay on line and the Loss of DC AOP would be entered. The outside containment letdown isolation valve [2CV-4823-2] is air operated and the air supply is controlled by a green DC solenoid. When green DC is lost, the valve will fail closed isolating letdown and cause Pzr level to be maintained by cycling CCPs.

A. Incorrect. The Unit does not trip automatically nor is it an action required by the AOP to trip the Reactor and go to SPTAs upon a loss of Green DC. Plausible because a loss of Green DC does automatically open 2 trip circuit breakers but this does not cause a Reactor trip.

B. Incorrect. The Unit does not trip automatically nor is it an action required by the AOP to trip the Reactor and go to SPTAs upon a loss of Green DC. Plausible because a loss of Green DC does automatically open 2 trip circuit breakers but this does not cause a Reactor trip.

C. Incorrect. The Loss of DC AOP is entered but the Letdown Isolation valve inside containment does not automatically close upon a loss of Green DC. Plausible because letdown does isolate on a loss of Green DC, but it is the Letdown Isolation valve outside containment that closes not the valve inside containment.

A. Correct Notes:

Aligns with T.S. 3.7.4.1 bases for the minimum indicated ECP level of 5.2 feet. This requirement is based on soundings and includes measurement, calculation and other uncertainties (equivalent to 0.15 ft) to ensure a minimum contained water volume of 70 area-feet crediting operator action to initiate makeup to ECP upon loss of Dardanelle Reservoir. The additional water added to the ECP during the time between first swapping the returns to the ECP and then later swapping the suctions to the ECP will maintain the ECP >70 area-feet and provide adequate supply of water for a 30 day supply of cooling water to ECCS components to operate without exceeding their design base temperature.

Comments on Q81_R1 There are a couple follow-on comments:

1) Text was added indicating that this question will now have a reference provided (the word REFERENCE is misspelled, by the way). The reference needs to be clearly identified on the Worksheet and needs to be sent to NRC (if we dont already have it) so we can review it prior to accepting the question as satisfactory. The reference will also need to be included in the revised question file when the exam is submitted again.

2) On answer B, revise it to say Demonstrate the operability of the remaining offsite AC circuit. The word offsite is used in the Technical Specifications text (LCO 3/4.8.1, Action c.1).

3) There are still some minor edits that were identified on the worksheet we sent to you as comments for R0 on January 26th.

Comments on Q82_R1 The changes made addressed BTLs markups. It is satisfactory from that perspective.

The question is SRO level of knowledge, but it isnt clear how this ties to the K/A statement.

The question doesnt appear to test knowledge of the LCOs or Safety Limits. If applying the AOP is implementing a Surveillance Requirement driven by the LCO Action Statement for one CEA inoperable, then the tie could be established. With the given references, this isnt clear.

If the tie to the KA can be established, enhance the Notes and submit as R2.

Description:

Ability to determine and interpret the following as they apply to the Emergency Boration: - Whether boron flow and/or MOVs are malfunctioning, from plant conditions Question:

Consider the following:

- Unit 2 is operating at 100% power

- Annunciator 2K12 B-2 "HEADER PRESS LO" for the Coolant Charging Pumps (CCPs) comes into alarm

- Annunciator 2K12 B-3 "HEADER FLOW LO" for the CCPs comes into alarm

- Volume Control Tank (VCT) level is 58% and lowering

- The WCO reports a rupture in the CCP suction header downstream of the RWT supply valve, 2CV-4950-2 and check valve

- OP-2203.036, Loss of Charging AOP, has been entered and the CRS directs tripping the Unit

- The ATC reports 3 CEAs did not fully insert on the trip and reactor power is 0.2% and steady

- SPTAs have been completed The CRS would diagnose _____________________________ and Emergency Boration would be accomplished by A. OP-2202.009, Functional Recovery EOP; aligning CCP discharge to the #1 HPSI header B. OP-2202.009, Functional Recovery EOP; lowering RCS pressure and starting a HPSI pump C. OP-2203.032, Emergency Boration AOP; aligning CCP discharge to the #1 HPSI header D. OP-2203.032, Emergency Boration AOP; lowering RCS pressure and starting a HPSI pump Answer:

B. Correct Notes:

With the given conditions entering Functional Recovery and depressurizing the RCS to allow using HPSI to emergency borate is correct. The location of the charging suction header rupture is unisoable from the rest of the system rendering all CCPs incapable of adding inventory to the RCS. With >1 CEA not fully inserted and reactor power >.1% and stable requires the addition of boron to meet shutdown margin. The Emergency Boration AOP does contain direction to depressurize and use a HPSI pump but it is not addressed on the exhibit 8 as an option to enter post SPTAs with the reactivity safety function not met. Standard Attachment Exhibit 1, Emergency Boration, would have been attempted during SPTA's, but would have not have been successful. Emergency Boration AOP is not one of the procedures that can be diagnosed coming out of SPTAs.

Comments on Q84_R1 From S. Hedger:

In Revision 1 to the question, the K/A statement has changed. It changed from 069 Loss of Containment Integrity, K/A A2.02, to K/A G2.1.1. In looking at this, and Question 83, I suspect that a swap of the A2 and G K/As for these was completed. However, it this isnt something that has been negotiated, it is captured here for follow up.

The question has been revised to test an additional area of knowledge that is SRO-only in nature. Therefore, this is now a SRO-only question. There is no justification for the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> time requirement being plausible, but it is better than the previous options. It is satisfactory.

From B. Larson:

ES-401-4, Record of Rejected KAs, Rev 1, does NOT contain an entry for changing the KA for this question. The change from an A2 to a Generic affects the Category Points for Tier 1, Group

2. Without a more detailed review, it appears as if now there is only 1 question for Tier 1, Group 2 which is not acceptable. Note 1 on the ES-401-2 form states Ensure that at least two topics from every applicable K/A category are sampled within each tier of the RO and SRO-only outlines. This needs to be resolved.

[REFERENCE PROVIDED]

Consider the following:

- Unit 2 is operating at 100% power

- Channel 1 Pressurizer (PZR) pressure transmitter (NR), 2PT-4601-1, has failed LOW

- CBOT bypasses ONLY point 5 (PZR pressure - HIGH)

Failure of another PZR pressure (NR) transmitter would cause a Reactor trip on ____________. This trip could of been prevented by applying Tech Spec 3.3.1.1 _______________ to bypass additional points in Channel 1.

A. Linear Heat Rate (LPD) and Departure form Nucleate Boiling Ratio (DNBR); Action 2 B. Linear Heat Rate (LPD) and Departure form Nucleate Boiling Ratio (DNBR); Action 3 C. Pressurizer pressure LOW; Action 2 D. Pressurizer pressure LOW; Action 3 Answer:

A. Correct Notes:

With one channel failed low (PZR pressure channel 1) LPD and DNBR will also be in a tripped condition on channel 1.

T.S.3.3.1.1 action b requires points 3, 4, and 5 in either tripped or bypass within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Without placing points 3 and 4 in bypass for channel 1 the reactor trip logic is in a 2 out of 4 logic with 1 point already tripped, therefore it would only take 1, more PZR pressure channel to fail low (which would also trip LPD and DNBR for that channel) to cause a reactor trip.

which initially directs the operators to ___________.

A. OP-2203.003, CEA Malfunctions AOP; insert Reg Group 5 CEAs in Manual Group to clear the alarm B. OP-2203.003, CEA Malfunctions AOP; ensure rod motion has stopped and notify I&C to perform troubleshooting on CEA Reg Group 5 C. OP-2105.009, CEDM Control System Operation; insert Reg Group 5 CEAs in Manual Group to clear the alarm D. OP-2105.009, CEDM Control System Operation; ensure rod motion has stopped and notify I&C to perform troubleshooting on CEA Reg Group 5 Answer: C Comments: Previous comment was that the question did not ask an SRO level of knowledge, so the proposed revision above changes the stem and answers to make the applicant choose the procedure that would be used to make the question SRO level. Per alarm response procedure OP-2203.012J, if the alarm is in due to improper reg group overlap, the direction is to reposition the group to clear the alarm using OP-2105.009, making answer C correct. The use of the CEA Malfunction AOP as a response to this event is plausible because of the groups getting out of sequence. However, this is not listed as an entry condition to the AOP, therefore

distractor A and B are plausible but incorrect. Notifying I&C to perform troubleshooting is listed as a step in the AOP, making distractors B and D plausible but incorrect. Troubleshooting would likely be performed due to the sequence problem, but it is not listed in the procedure, and would be performed after the operators insert Reg Group 5 to clear the alarm.

Question:

Consider the following:

- Unit-2 is operating at 100% power

- Annunciator 2K12 G-5 "VCT 2T4 LEVEL LO LO" comes into alarm

- 2LIS-4857, VCT level on 2C09 reads 68%

- 2LR-4857, VCT chart recorder on 2C09 reads 68% and steady

- It has been determined 2LT-4861 has failed low

- RCS Tave 578°F and trending down

- Pressurizer level is 59% and trending down slowly The Control Room staff would determine there is a ______________________ event in progress and the CRS would initiate actions referencing ____________________________________ .

A. dilution; EN-OP-115, Conduct of Operations B. boration; EN-OP-115, Conduct of Operations C. dilution; EN-OP-111, Operational Decision Making Issue (ODMI) Process D. boration; EN-OP-111, Operational Decision Making Issue (ODMI) Process Answer:

B. Correct Notes:

Due to the false low VCT level signal, CV-4873-1, VCT outlet, would automatically close and 2CV-4950-2, CCP suction source from the RWT would automatically open aligning an Emergency Boration flowpath to the RCS. Once aligned, reactor temperature will trend down, reactor power will maintain somewhat constant due to steam demand not changing (MTG is controlled in manual). The CRS should recognize this and secure CCPs (or take manual control of the VCT and RWT valves and realign CCP suction to the VCT) referencing EN-OP-115, Conduct of Operations, Section 5.4, Manual Control of Automatic Systems.

A. Incorrect. Based on the above note, there is a boration in progress, not a dilution.

B. Correct. Based on the above note, there is a boration in progress and the CRS would use the guidance in EN-OP-115 to manual control of the failed automatic system and restore the proper suction source to the Charging Pumps.

C. Incorrect. Based on the above note, there is a boration in progress, not a dilution.

D. Incorrect. There is a boration in progress, but EN-OP-111 does not contain the guidance to take manual control of an automatic system that is malfunctioning. Plausible because the operators will use the guidance in EN-OP-111 to create an ODMI for this malfunction, but that will be performed at a later time.

1. Q77 - question is no longer a MODIFIED, it is NEW. Update and submit Rev 2 with explanation added for Rev 2. Changed to NEW question and changed to Rev 2.

2. Q78 - there are two copies of Rev 1, and they have different Notes and different Rev Dates. Change the Rev 1 dated 1/30/2014 to Rev 2 and add a description of Rev 2 to the Historical Comments. Changed the Rev. 1 dated 1/30/14 to Rev 2 and updated historical comments.

3. Q81 - For B change circuit to circuits. This was identified but missed. Changed circuits to circuit and changed to Rev 3.

4. Q84 - need to verify the Revision numbers. There are two Rev 1s with different answers. (Pages 2 and 3 of 10). How is it possible to have 2 different sets of answers yet the Rev Date blocks are identical? Deleted one of the Rev 1s.

5. Q85 - There are two Rev 1s with different Rev Dates. Is Rev 1 dated 1/30/2014 actually Rev 2? If so, update and add comment in the Historical Comments. Updated to Rev 2 and added historical comments.

6. Q93 - we sent Recommendations to Rev 1: no Rev 2 was returned. Deleted Rev. 1 dated 10/22/13. Created new Rev. 2 incorporating NRC comments.

Notes:

1. On several questions, the second page of the latest revision of worksheet is out of place

- its been the last page of the file. Caused by the way the pdf documents were merged together. Are in the correct order in our book and will be in next electronic transmission.

2. Have your team start looking at the RO questions, starting with Q1, and check all files for proper revision numbers (so we can track the pedigree of each question) and check that the worksheet pages are in the proper order (first page or two of the file should be the worksheet for the latest rev of the question, and then previous rev(s) worksheets. RO questions 1-50 are completed and are starting on 50-75.

3. Files should be in chronological order - for example: If the K/A was changed for Rev 0 question, then file should be Rev 1 (new question), Rev 1 reference material, then Rev 0 question, then Rev 0 reference material. As we are completing step 2 above, we are copying the reference material and putting it with each rev in chronological order.

4. Make sure we accurately identify all questions that were used on last 2 NRC exams, and all questions with Reference Provided. We have went back and identified all questions that were on the past 2 NRC exams and all questions with Reference Provided.

February 18, 2014 SRO Exam (continued)

1. Q88 - file is missing Rev 0 worksheet. We have the Rev 0 worksheet ready to scan when next electronic document is sent.

2. Q89 - file has 2 Rev 1s, dated 1/22 and 1/30. At first glance, I dont see any differences between the two worksheets. Either ensure they are the same and delete one of them (and then change Rev 3 to Rev 2) or find out if they are different, then change one of them to Rev 2 (with a comment as to what was changed in Historical Comments). Also, the second page of the Rev 3 worksheet was the last page of the file. Deleted Rev 1 dated 1/22. Will correct order of scanned documents when next electronic doc is sent.

3. Q90 - second page of Rev 2 worksheet was the last page of the file. Will correct the order of scanned docs when next electronic doc is sent.

4. Q91 - confirm NO reference provided. File has 2 Rev 1s dated 1/22 and 1/30. The only difference I see is that the one dated 1/30 has a Rev 1 entry in the Historical Comments section. Either ensure they are the same and delete one of them (leave Rev 2 as Rev 2) or find out if they are different, then change one of them to Rev 2 (with a comment as to what was changed in Historical Comments) and then change Rev 2 to Rev 3. Also, the second page of the Rev 2 worksheet was the last page of the file. Deleted Rev 1 dated 1/22.

5. Q92 - second page of Rev 1 worksheet was the last page of the file. Will correct order of scanned docs when next electronic doc is sent.

6. Q93 - [file contains 2 Rev 0s, both with the same Rev Date: (10/22/2013). The question is clearly different on each rev. The one worksheet with Rev 0 written on top of the worksheet was the version that was submitted with the Draft Exam. That would make one of the Rev 0s actually Rev 1, and then Rev 1 would be Rev 2. In addition, we have comments we sent on Rev 1 (which is probably actually Rev 2).] - comments sent to Clay via email. Deleted Rev. 1 dated 10/22/13. Created new Rev. 2 incorporating NRC comments.

7. Q94 - (Rev 2 is a new question based on a new K/A. Was this K/A discussed with NRC examiner? We had sent comments on Rev 1 to make the question acceptable - why was the K/A changed? Also, the notes for Rev 2 in the Historical Comments section doesnt identify that a new K/A was selected. Was this new K/A added to the written exam outline and included on the ES-401-4, Record of Rejected K/As?) This question is Q95, not Q94. We need Rev 2 of Q94. Also, there are 2 Rev 1s in the file, dated 1/22 and 1/30. The one dated 1/30 has a note in Historical Comments and the other doesnt.

Questions 94 and 95 corrected in Exam bank. Kept Rev 1 dated 1/30.

8. Q96 - file has 2 Rev 2s, appear to be the same. File has 2 Rev 1s, dated 1/30 and 1/22, and questions are clearly different. Need to resolve revision status with remarks updated accordingly in the Historical Comments section. Deleted Rev 1 dated 1/22. This question was never submitted.

9. Q98 - file is missing Rev 1 and Rev 0. Will include all revs when next electronic doc is sent.

10. Q99 - page 2 of worksheet was the last page in the file. Correct order in book, will be in correct order when next electronic doc is sent.

11. Q100 - page 2 of worksheet was the last page in the file. Also, file is missing Rev 1 worksheet. Will include rev 1 in next electronic doc sent. Correct order in book, will be correct order when next electronic doc is sent.

12. Q83- Incorporated Rev 0 changes. No changes needed per Rev 1 comments from Larson and Hedger.

a. Rev 0 was Unsat due to K/A mismatch. How does question address operational implication of natural circ? See R0 comments.

2. Q7

a. Rev 0 identified question as Unsat since part 2 of all answers are unique. That is still true on Rev 3. What value is there in asking part 1 of the question?

b. Why did you put on a Main Steam Isolation Signal (MSIS) back into all answers?

3. Q10

a. First bullet in stem - refers to 80 gpm tube leak, then next bullet says SG Tube Rupture. Would it be more accurate to call the 80 gpm leak a rupture?

4. Q11

a. In stem, the word Demand is misspelled (Deman).

b. In stem, the step in 2202.005 is 14, not 12. I have Rev 14 of the EOP. It is step 12 in the ESD Tech Guide, which is Rev 13. Im guessing the EOPs and their Tech Guides are kept at the same revision so update question stem to step 14 and update References EOP-2202.005 Basis Document to Rev 14.

c. Since the question is referencing a step in 2202.005, add 2202.005 to References.

d. Also, since the step is in quotation marks, change to WHEN RCS TC less than 510°F, THEN reduce number of running RCPs as follows:

e. Also, delete Emergency Operating Procedure after step 14 of

f. Change Taxonomy from H to F. LOD is still 4.

g. In Notes, should be greater than three

5. Q12

a. How did validation go for this question? Im wondering what the value of the 2nd part of the answer is since all answers are different for part 1.

b. In stem, change RCS cooling to RCS heat removal

c. Also, change Pump to pump after Condensate.

d. Should we add as last bullet CRS has entered OP-2202.009, Functional Recovery EOP?

6. Q14

a. Recommend deleting ONE (1) in your database - no revision required.

Rev 4 Question Technical Review RO Draft Written Exam 2 February 23, 2014

1. Q43

a. Rev 2 - Notes say With no operator action, SG levels would continue to rise until the HLO setpoint of 82% level was reached. At that point, the HLO signal goes around the Master controller and straight to the individual component controllers Is this correct? The answer C says operator action IS required to prevent a HLO from occurring. If the HLO signal goes around the Master controller, why is operator action required? Also, OP-2106.007 says if the controller is in manual, HLO signals can NOT perform their function.

b. Is the stem correct to say prevent a HLO from occurring or should it say minimize moisture carryover?

2. Q44

a. Is it normal for 2P-75 to be running for the conditions given in the stem (startup completed, raising power, current power 5% and trending up)? If so, when is 2P-75 procedurally secured?

b. A - Part 1 states the FCS will automatically raise 1B speed and SG levels will be maintained at setpoint, but part 2 says to place 1B in service how can part 1 be true if 1B isnt in service? Not plausible. Also, the Notes for A discuss 2P-75, not raising 1B speed. Why not use a 2x2 question format? Part 1 is either automatically maintain SG levels at setpoint OR require manual operator action to restore SG levels to setpoint. Part 2 is either place B Main Feedwater pump (2P-1B) in service OR attempt to restart A Main Feedwater pump (2P-1A).

(This is what the Examiner proposed to Revision 1.)

3. Q45

a. Comment to Rev 1 wasnt addressed: What is significance of 15 minutes after trip? Is it a carryover from Rev 0? If left in the question, does it have the possibility of confusing the applicants?

b. Comment to Rev 1 wasnt addressed: Why is 150 gpm plausible for A and C?

4. QQ47

a. For you database - recommend putting bus at end of stem and remove from each answer, adding commas after bus in A and B (like C and D), and Notes should identify at least one major load for each distractor. Rev not required.

b. Adding the voltage of the bus could be considered cueing (applicant could reduce incorrect choices by half just knowing RCPs are 6900 V). Revision not required.

c. Not just related to this question, but why did you remove question numbers from the ES-401-2? How do you relate a K/A to a specific question?

5. Q48

a. Changed LOD=3 and Taxonomy changed to H. No revision required.

6. Q49

a. Comments were provided on Rev 1 - were they addressed? Comments:

The change did not address the concern.

The basis for the proposed correct answer says that the loss of 125 VDC control power prevents any remote manual operations. Based on Answer Cs wording,

Rev 4 local manual means must be available as the only option for operating the affected breakers.

When the wording of distracter B is reviewed, it says Breakers would be able to be operated remotely.. Is operating a breaker by local manual means, considered remotely? An applicant could argue if this is vague that operating the breaker by local manual means can be completed outside the Control Room, so it is remote. If there is a specific site definition for remotely that will ensure that distracter B is not correct, it needs to be documented in the question notes.

If there isnt a basis, the next best thing would be to modify distracter B to say Breakers would be able to be manually operated remotely,..

The goal is to have all the terms clear so that there is no room to argue that there are two correct answers.

b. Answers are adequate, but more complicated than necessary for LOD=2 knowledge.

c. If the question or format is changed, then swap C and D for shortest to longest. This will change right answer from C to D

Question Technical Review SRO Draft Written Exam 2 Generic Question:

1. Why do most of the SRO-only questions have RO lesson plans identified? Are there SRO lesson plan numbers available?

1. Q76

a. Will a 1% change in PZR level cause a change in Letdown? Concern is that the PZR level control system will automatically adjust to a lowering level so the info in the question stem would not be accurate. PZR level would not be 59% in 3 minutes if the level control system responds as designed.

b. The value used for Volume vs Level for the PZR is not correct. Per the ref, it is 53.5 gal/%, not 55.3. This affects the leakrate calculation (29.1 gpm vs 29.7) but doesnt affect the correct answer since it is still within the capacity of available CCPs.

c. The Notes section states SIAS would be actuated due to the RCS leakage - is this true? With two available CCPs (B & C) after the Reactor trip, how will pressure lower enough to initiate an SIAS with only a 29.1 gpm leak?

d. Explanation for C is incorrect - the second half should state that is it plausible because the applicant may not recognize Excess Leakage plus LOOP is LOCA EOP.

2. Q:88

a. Question on Rev 0 asked why just A spray pump since procedure says both.

Note on Rev 1 says Only the A Spray pump inadvertently starts in this scenario. B Spray pump is not running. How does the applicant know this?

3. Q:90

a. This is the second question that tests Excess RCS Leakage AOP combined with a LOOP = LOCA EOP.

4. Q92

a. Not having a procedure for this event could be an Appendix B violation. Make sure this gets submitted for evaluation after the exam is completed. Does ANO still think this question should be used on the written exam?

5. Q95

a. Comment on Rev 0 stated COPD-030 could be correct and identified page 10, Section 4.5, 11th bullet. Rev 1 Notes says COPD-030 not correct but identified Section 5, Step 5.5. What about Section 4.5, 11th bullet since it specifically identifies transients? Could the applicant argue this bullet also makes Answer B as correct? Also, recommend adding the applicable AOP to the Notes section to directly relate given conditions in the stem do constitute entry into an AOP, thus making COPD-030, Step 5.5 more applicable.

6. Q98

a. FYI - changed LOD to 4. Also, Notes dont appear to have been updated. No revision required but updates should be made to your database.

7. Q99

a. FYI - changed LOD to 3. No revision required.

8. Q100

a. Second bullet - Rev 0 identified Owners should be Owner but not corrected. If okay with ANO, no revision is required but you should correct in your database.
